about using more variable-width fonts, + + +27 +0:01:06,000 --> 0:01:08,000 +which would probably go a long way to + + +28 +0:01:08,000 --> 0:01:11,000 +making Emacs look pretty fancy once people + + +29 +0:01:11,000 --> 0:01:13,000 +sort out the alignment issues. + + +30 +0:01:13,000 --> 0:01:15,000 +It looks like core Emacs will probably + + +31 +0:01:15,000 --> 0:01:18,000 +change slowly in terms of functionality and documentation, + + +32 +0:01:18,000 --> 0:01:21,000 +but starter kits and configuration give people + + +33 +0:01:21,000 --> 0:01:22,000 +a great way to experiment. + + +34 +0:01:22,000 --> 0:01:24,000 +Speaking of starter kits, + + +35 +0:01:24,000 --> 0:01:27,000 +Doom Emacs seems to be growing in popularity. + + +36 +0:01:27,000 --> 0:01:28,000 +It got a big boost thanks to DoomCasts and + + +37 +0:01:28,000 --> 0:01:32,000 +DistroTube videos. So if you're curious, + + +38 +0:01:32,000 --> 0:01:35,000 +go ahead and check those out. + + +39 +0:01:35,000 --> 0:01:37,000 +And for general Emacs topics, + + +40 +0:01:37,000 --> 0:01:38,000 +there have been a ton of other great videos + + +41 +0:01:38,000 --> 0:01:42,000 +from Protesilaos Stavrou, Mike Zamansky, System Crafters, + + +42 +0:01:42,000 --> 0:01:45,000 +and other folks.

You find + +0:03:05.920,0:03:09.040 +something + +0:03:06.640,0:03:10.239 +that's interesting. You add it to your + +0:03:09.040,0:03:11.680 +Emacs configuration. You + +0:03:10.239,0:03:13.519 +barely understand anything that's going + +0:03:11.680,0:03:14.800 +on. You know that it's supposed to be + +0:03:13.519,0:03:17.200 +Emacs Lisp. + +0:03:14.800,0:03:19.440 +"I hardly know Emacs and I + +0:03:17.200,0:03:21.440 +know even less what is Lisp supposed to be." + +0:03:19.440,0:03:22.800 +But you paste it in and it does what you + +0:03:21.440,0:03:26.959 +want it to do, and you say + +0:03:22.800,0:03:29.280 +"Great, I'll move on to my work now." So + +0:03:26.959,0:03:30.879 +that's how I got started. I had + +0:03:29.280,0:03:33.440 +a very spartan + +0:03:30.879,0:03:35.200 +setup for Emacs, which a lot of you must + +0:03:33.440,0:03:36.000 +know... The first time you launch Emacs, + +0:03:36.000,0:03:39.599 +you have this feeling that you're jumping 20 + +0:03:37.840,0:03:43.680 +years back in time, as far as the + +0:03:39.599,0:03:45.920 +user interface is concerned. But + +0:03:43.680,0:03:46.959 +as you get to spend more time with Emacs... + +0:03:46.959,0:03:50.959 +Some would call it Stockholm syndrome + +0:03:49.120,0:03:53.360 +insofar as you can't see + +0:03:50.959,0:03:54.640 +how spartan the entire thing is, but it + +0:03:53.360,0:03:58.400 +actually is + +0:03:54.640,0:04:00.400 +a lovely prison so to speak. + +0:03:58.400,0:04:01.680 +That's how I got started eight years + +0:04:00.400,0:04:04.319 +ago. I just wanted + +0:04:01.680,0:04:05.519 +to find a way to do my research properly. + +0:04:04.319,0:04:07.280 +I wanted to have a + +0:04:05.519,0:04:08.959 +tool that I could use to write my notes + +0:04:07.280,0:04:11.680 +in plain text, because I was already + +0:04:08.959,0:04:14.560 +fairly averse to + +0:04:11.680,0:04:16.320 +Microsoft solutions when it + +0:04:14.560,0:04:19.359 +came to taking notes. + +0:04:16.320,0:04:20.880 +So yeah, I got started in emacs.

I believe they're pretty + +0:16:28.000,0:16:32.079 +pretty good. + +0:16:29.600,0:16:33.199 +There was another question.

Okay. So that's a very good + +0:17:28.240,0:17:33.840 +question. I believe + +0:17:30.400,0:17:35.840 +alphapapa is in the chat right now. + +0:17:33.840,0:17:37.760 +As myself a new lisp developer for + +0:17:35.840,0:17:38.320 +org-roam, i'd really recommend you to look into + +0:17:38.320,0:17:42.799 +his package developers' guide because you + +0:17:40.640,0:17:44.559 +have a list of all the softwares that + +0:17:42.799,0:17:45.760 +are extremely useful to be using when + +0:17:44.559,0:17:48.000 +you're getting started. + +0:17:45.760,0:17:50.000 +If you're looking into a first + +0:17:48.000,0:17:52.640 +step for how to develop + +0:17:50.000,0:17:53.520 +elast package, i'd really advise you to + +0:17:52.640,0:17:56.559 +look into edebug. + +0:17:53.520,0:17:58.000 +It's one word, edebug, + +0:17:56.559,0:17:58.400 +and you have a section in the manual for this, + +0:17:58.400,0:18:01.919 +because for me, it was the key step to + +0:18:00.799,0:18:04.320 +getting to + +0:18:01.919,0:18:05.679 +develop good packages. It was + +0:18:04.320,0:18:06.160 +understanding basically what the code did + +0:18:06.160,0:18:09.919 +and having us something like a + +0:18:08.960,0:18:11.760 +REPL (read-evaluate-print-loop) + +0:18:09.919,0:18:13.360 +that allows you to step through the code + +0:18:11.760,0:18:13.919 +and see exactly which states the + +0:18:13.360,0:18:16.000 +variables are at which at this point in the + +0:18:16.000,0:18:20.080 +program.

Yeah, I see one + +0:18:24.400,0:18:28.240 +or two more. + +0:18:26.160,0:18:30.080 +So there's one.

I mentioned + +0:18:36.480,0:18:40.320 +that Emacs, for me, was my gateway + +0:18:38.080,0:18:41.360 +into free software and the freedom of + +0:18:40.320,0:18:43.840 +Emacs was that + +0:18:41.360,0:18:44.960 +you could maybe... First and foremost, + +0:18:43.840,0:18:47.840 +compared to + +0:18:44.960,0:18:48.400 +other software, was that you had + +0:18:47.840,0:18:51.039 +behind Emacs, + +0:18:48.400,0:18:52.400 +Elisp, which allows you to read the code, + +0:18:51.039,0:18:53.039 +read whatever is going on in the + +0:18:52.400,0:18:54.640 +background. + +0:18:53.039,0:18:56.160 +Surely, if you go deep enough, you'll + +0:18:54.640,0:18:58.000 +end up on + +0:18:56.160,0:18:59.679 +C functions that you might not be able to + +0:18:58.000,0:19:02.000 +read if you do not have the experience. + +0:18:59.679,0:19:03.520 +But for Org Mode, which was my gateway + +0:19:02.000,0:19:06.400 +into Emacs, + +0:19:03.520,0:19:08.240 +most of it is written in Elisp, and all + +0:19:06.400,0:19:10.080 +the commands have a very verbose + +0:19:08.240,0:19:13.440 +name, like something simple as + +0:19:10.080,0:19:15.840 +org go to next subtree or + +0:19:13.440,0:19:16.880 +org go to a parent subtree. You know, things + +0:19:15.840,0:19:20.240 +like this. + +0:19:16.880,0:19:22.799 +It's so elegant.

"What's the + +0:21:06.880,0:21:10.159 +most recent Emacs package or tool that + +0:21:08.960,0:21:14.480 +you've discovered + +0:21:10.159,0:21:17.600 +that you've added to your repertoire?") + +0:21:14.480,0:21:20.320 +Very interesting question. + +0:21:17.600,0:21:20.799 +The thing is, + +0:21:20.799,0:21:23.919 +when you've spent as long as I have on + +0:21:22.320,0:21:25.120 +Emacs--and I know that I've only spent + +0:21:23.919,0:21:28.799 +eight years and some of you + +0:21:25.120,0:21:30.000 +might have spent maybe 10, 20, maybe even + +0:21:28.799,0:21:32.799 +more years on Emacs-- + +0:21:30.000,0:21:35.120 +but for me, I believe the the coolest + +0:21:32.799,0:21:38.200 +neat trick that I found in Emacs was + +0:21:35.120,0:21:40.080 +a mode which is called beacon-mode. + +0:21:40.080,0:21:43.679 +It's something that allows + +0:21:42.559,0:21:45.120 +you to show + +0:21:43.679,0:21:46.960 +when you're jumping between buffers or + +0:21:45.120,0:21:49.760 +when you're dropping between windows, + +0:21:46.960,0:21:51.520 +it shows exactly where your point is in + +0:21:49.760,0:21:53.840 +that buffer by making + +0:21:51.520,0:21:55.440 +a slight ray of light which looks like a + +0:21:53.840,0:21:57.760 +beacon, hence the name. + +0:21:55.440,0:21:59.520 +It really helps you navigate buffers + +0:21:57.760,0:22:01.760 +because it always shows in a very + +0:21:59.520,0:22:03.520 +visual way where your point is. + +0:22:01.760,0:22:04.640 +I'll get a chance to show this to + +0:22:03.520,0:22:08.720 +you later today + +0:22:04.640,0:22:08.720 +when i'll be presenting my other talks. + +0:22:10.159,0:22:16.880 +(Amin: AWesome. + +0:22:13.840,0:22:20.159 +We have one question + +0:22:16.880,0:22:20.880 +from Jonas, the maintainer + +0:22:20.159,0:22:24.720 +from Magit. + +0:22:20.880,0:22:26.880 +He asks, "When you touched your + +0:22:24.720,0:22:29.600 +webcam, that blew a fuse at my place. + +0:22:26.880,0:22:29.600 +How did you do that?") + +0:22:29.760,0:22:32.960 +Well, I'm very sorry, Jonas, that it + +0:22:31.600,0:22:36.000 +happened to you, but i'll make sure not + +0:22:32.960,0:22:36.000 +to touch my webcam again. + +0:22:36.960,0:22:43.919 +(Amin: Do we have any other questions?) + +0:22:41.600,0:22:45.840 +I have to trust you on this one. + +0:22:43.919,0:22:46.960 +I'm really sorry.

sheet + +0:00:09.599,0:00:14.320 +music in emacs + +0:00:10.880,0:00:18.400 +using lily pond and maybe also convince + +0:00:14.320,0:00:18.400 +you to use emacs for writing your scores + +0:00:18.640,0:00:22.240 +so i'll start with an overview of the + +0:00:20.400,0:00:24.400 +syntax for those who are new to using + +0:00:22.240,0:00:26.800 +text based notation +

+0:00:40.480,0:00:46.800 +so what is lillipond lillipond is + +0:00:44.079,0:00:50.000 +a file format and music engraving system + +0:00:46.800,0:00:52.640 +for producing high quality sheet music + +0:00:50.000,0:00:55.120 +it translates texture representations of + +0:00:52.640,0:00:57.760 +music to graphical objects + +0:00:55.120,0:01:00.000 +so it's similar to latex in that its + +0:00:57.760,0:01:01.600 +input format describes the visual + +0:01:00.000,0:01:03.520 +layouts of the score + +0:01:01.600,0:01:05.119 +using commands to define musical + +0:01:03.520,0:01:07.760

+so on and so forth + +0:01:19.119,0:01:23.119 +it's also fully extensible like emacs + +0:01:21.600,0:01:25.600 +allowing users to extend + +0:01:23.119,0:01:26.640 +and override lilipon's functionalities + +0:01:25.600,0:01:29.840 +using the scheme + +0:01:26.640,0:01:31.600 +scripting language it can be used for + +0:01:29.840,0:01:34.479 +early in contemporary music +

+0:01:38.479,0:01:43.119 +lily pond ships with imax lisp libraries + +0:01:41.040,0:01:45.920 +including a major mode for editing lily + +0:01:43.119,0:01:45.920 +pawn files + +0:01:47.360,0:01:50.560 +so the input files are similar to source + +0:01:50.000,0:01:52.560 +files + +0:01:50.560,0:01:54.079 +they contain expressions formed with + +0:01:52.560,0:01:55.840 +curly braces + +0:01:54.079,0:02:00.159 +comments that start with the percent + +0:01:55.840,0:02:00.159 +sign and the code is indented + +0:02:00.240,0:02:05.600 +nodes are entered using lowercase + +0:02:02.159,0:02:08.800 +letters and rests with the letter r + +0:02:05.600,0:02:11.039 +in this case the lowercase r or r4 + +0:02:08.800,0:02:14.000 +is the equivalence of a crotchet or + +0:02:11.039,0:02:16.160 +quarter note rest + +0:02:14.000,0:02:18.480 +durations are entered using numbers and + +0:02:16.160,0:02:20.959 +dots after the note name + +0:02:18.480,0:02:22.640 +and if you do not specify 1 the previous + +0:02:20.959,0:02:24.560 +duration is used + +0:02:22.640,0:02:27.360 +you can also tie notes together using + +0:02:24.560,0:02:30.000 +the tilde symbol + +0:02:27.360,0:02:32.080 +in fact you can input chords lyrics + +0:02:30.000,0:02:33.920 +embellishments and a lot more + +0:02:32.080,0:02:36.160 +so i encourage you to read the menu for + +0:02:33.920,0:02:39.680 +more information + +0:02:36.160,0:02:42.000 +now let's switch to a terminal window + +0:02:39.680,0:02:43.840 +so with lillipond installed let's create + +0:02:42.000,0:02:50.560 +a test file with the extension + +0:02:43.840,0:02:52.400 +ly and open it in emacs + +0:02:50.560,0:02:54.800 +at the top of the file is the version + +0:02:52.400,0:02:57.440 +statement which tells lillipond which + +0:02:54.800,0:03:00.959 +version to use when compiling the file + +0:02:57.440,0:03:03.680 +here i'm using version 2.20.0 + +0:03:00.959,0:03:04.159 +i've added the clef and time signature + +0:03:03.680,0:03:07.440 +so + +0:03:04.159,0:03:07.440 +let's add some notes + +0:03:09.280,0:03:14.560 +okay i'm going to close this now and + +0:03:12.400,0:03:19.760 +compile the file by running + +0:03:14.560,0:03:25.040 +lily pawns followed by the file name + +0:03:19.760,0:03:25.040 +okay so now let's view the outputs + +0:03:27.360,0:03:32.239 +okay so here's a more complex example + +0:03:29.760,0:03:34.080 +for randomizing node sequences + +0:03:32.239,0:03:36.239 +the idea is to create new reading + +0:03:34.080,0:03:37.760 +materials each time the code blocks are + +0:03:36.239,0:03:40.640 +evaluated + +0:03:37.760,0:03:41.840 +so as usual we begin with a header i've + +0:03:40.640,0:03:45.200 +added the title + +0:03:41.840,0:03:47.920 +and composer then we add the node + +0:03:45.200,0:03:50.879 +sequences to use in the composition + +0:03:47.920,0:03:51.200 +in this case s n is a note name just + +0:03:50.879,0:03:54.400 +like + +0:03:51.200,0:03:54.959 +a b c d and so on and stands for snare + +0:03:54.400,0:03:58.239 +drum + +0:03:54.959,0:03:58.239 +the percussion instruments + +0:03:58.879,0:04:04.080 +now here's a function that's going to + +0:04:00.720,0:04:06.560 +shuffle the notes in the table + +0:04:04.080,0:04:08.799 +and finally we expand the notes inside + +0:04:06.560,0:04:10.799 +the lillypawn source block + +0:04:08.799,0:04:13.680 +so whatever the function returns is + +0:04:10.799,0:04:16.479 +expanded inside the drums block + +0:04:13.680,0:04:19.120 +now let's press ctrl c ctrl c to view + +0:04:16.479,0:04:19.120 +the results + +0:04:20.079,0:04:26.800 +okay and if i run this again it should + +0:04:23.280,0:04:26.800 +create a new composition + +0:04:26.840,0:04:31.360 +great you can also audition a piece + +0:04:29.680,0:04:34.320 +using the midi command + +0:04:31.360,0:04:36.560 +which creates a midi file of the score + +0:04:34.320,0:04:39.040 +note also that the ob library + +0:04:36.560,0:04:40.400 +sorry the ob lillypoint library comes + +0:04:39.040,0:04:42.560 +with two modes + +0:04:40.400,0:04:43.440 +the one i'm using now is called arrange + +0:04:42.560,0:04:45.440 +mode + +0:04:43.440,0:04:47.120 +and is useful for assembling complete + +0:04:45.440,0:04:49.360 +scores + +0:04:47.120,0:04:51.199 +the basic mode on the other hand allows + +0:04:49.360,0:04:53.360 +you to mix text and music + +0:04:51.199,0:04:55.440 +by embedding lily pawn snippets and + +0:04:53.360,0:04:57.840 +export them using typical org mode + +0:04:55.440,0:04:57.840 +commands + +0:05:00.240,0:05:04.320 +now to demonstrate the basic mode in + +0:05:02.320,0:05:05.120 +action i'm going to export this document + +0:05:04.320,0:05:08.240 +to a pdf + +0:05:05.120,0:05:10.639 +file in this case the + +0:05:08.240,0:05:11.919 +filehead argument is required so you + +0:05:10.639,0:05:15.280 +have to provide one + +0:05:11.919,0:05:15.280 +and include the file name + +0:05:15.600,0:05:20.479 +again you can run the code and view the + +0:05:17.919,0:05:20.479 +results + +0:05:22.160,0:05:30.080 +here it is so now let's + +0:05:25.840,0:05:30.080 +export this to pdf file + +0:05:33.680,0:05:41.440 +and here it is what it generates + +0:05:39.680,0:05:44.000 +now i'm going to show you the workflow i + +0:05:41.440,0:05:46.160 +used to produce music books in emacs + +0:05:44.000,0:05:48.000 +combining lily pond and latex for a + +0:05:46.160,0:05:50.160 +perfect marriage + +0:05:48.000,0:05:53.039 +i begin by sketching first draft of the + +0:05:50.160,0:05:55.039 +manuscript using pencil and paper + +0:05:53.039,0:05:57.440 +then i move to emacs to input the notes + +0:05:55.039,0:06:00.080 +in a git repository + +0:05:57.440,0:06:01.360 +this is a typical source file it begins + +0:06:00.080,0:06:03.199 +with a stylesheet + +0:06:01.360,0:06:05.440 +where i set variables and layout + +0:06:03.199,0:06:07.039 +settings although in general there's no + +0:06:05.440,0:06:09.280 +need for tweaking the layout + +0:06:07.039,0:06:11.199 +unless you have specific requirements to + +0:06:09.280,0:06:13.360 +do so + +0:06:11.199,0:06:15.520 +the easiest way to compile the file from + +0:06:13.360,0:06:19.280 +max is by pressing ctrl c + +0:06:15.520,0:06:21.199 +ctrl l so let's do this now + +0:06:19.280,0:06:23.759 +and the compilation buffer will tell you + +0:06:21.199,0:06:26.000 +if there were any errors in the file + +0:06:23.759,0:06:28.560 +now to automate the process of compiling + +0:06:26.000,0:06:31.280 +several files and building the pdf + +0:06:28.560,0:06:32.560 +i use gnu make so all i have to do is + +0:06:31.280,0:06:36.000 +open the shell + +0:06:32.560,0:06:37.840 +and run the make command and don't worry + +0:06:36.000,0:06:40.720 +i'll provide a link to the source code + +0:06:37.840,0:06:40.720 +on the last slide + +0:06:41.600,0:06:46.000 +as i moved forward with the project i + +0:06:43.600,0:06:48.720 +found at least two things missing + +0:06:46.000,0:06:50.479 +one i had no access to a metronome at + +0:06:48.720,0:06:52.960 +least not from the editor + +0:06:50.479,0:06:55.919 +so i built one for casual use and made + +0:06:52.960,0:06:58.000 +it available in the melpa repository + +0:06:55.919,0:06:59.039 +i also missed bar numbers in the source + +0:06:58.000,0:07:00.880 +file this + +0:06:59.039,0:07:03.199 +is useful when going back and forth + +0:07:00.880,0:07:04.479 +between input and output files without + +0:07:03.199,0:07:06.720 +getting lost + +0:07:04.479,0:07:08.479 +so i wrote a command for toggling bar + +0:07:06.720,0:07:10.000 +numbers which i hope you can see on the + +0:07:08.479,0:07:12.080 +left + +0:07:10.000,0:07:14.160 +also some expressions are difficult or + +0:07:12.080,0:07:17.039 +slow to write on the keyboard + +0:07:14.160,0:07:19.199 +accents and tuplets for example so i use + +0:07:17.039,0:07:20.160 +template expansion extensively for this + +0:07:19.199,0:07:23.280 +purpose + +0:07:20.160,0:07:23.280 +mainly yes snippets + +0:07:23.440,0:07:28.080 +so what do i think well i think + +0:07:25.680,0:07:31.039 +lillypond can be a sharp paradigm shift + +0:07:28.080,0:07:32.720 +but people used to gui alternatives but + +0:07:31.039,0:07:34.639 +the results are impressive + +0:07:32.720,0:07:36.960 +and you don't have to dive too deeply to + +0:07:34.639,0:07:38.880 +start using lillypod + +0:07:36.960,0:07:40.720 +likewise the ability to extend the + +0:07:38.880,0:07:42.400 +software i think is especially appealing + +0:07:40.720,0:07:45.199 +for music professionals +

talking about getting started + +0:00:06.240,0:00:11.200 +with Emacs today. + +0:00:08.960,0:00:13.040 +I have been an Emacs user for a long + +0:00:11.200,0:00:15.360 +time. First of all, thanks and a huge + +0:00:13.040,0:00:18.400 +welcome to the conference + +0:00:15.360,0:00:22.400 +from me and + +0:00:18.400,0:00:24.720 +and on behalf + +0:00:22.400,0:00:26.080 +and back to the other people that + +0:00:24.720,0:00:29.920 +have been helping to organize. + +0:00:26.080,0:00:30.480 +It's been amazing just to be involved + +0:00:30.480,0:00:35.120 +with that and just, kind of, see + +0:00:32.480,0:00:35.120 +backstage. + +0:00:36.399,0:00:42.960 +So I've used a lot of different editors + +0:00:39.680,0:00:45.440 +in my time. That's + +0:00:42.960,0:00:48.399 +about 25 years as a professional + +0:00:45.440,0:00:48.399 +software engineer. + +0:00:52.399,0:00:56.160 +And most of that time I've been using + +0:00:53.920,0:01:00.960 +Emacs. I'll talk a little bit in a minute + +0:00:56.160,0:01:04.479 +(if I can ever find my slides) + +0:01:00.960,0:01:07.200 +about how I got into Emacs + +0:01:04.479,0:01:10.240 +but I think if you've used Emacs and a + +0:01:07.200,0:01:12.640 +lot of other editors for a long time, + +0:01:10.240,0:01:14.960 +something that you notice right away is that + +0:01:15.200,0:01:18.560 +you get good with it in a way that stays + +0:01:17.520,0:01:20.799 +meaningful. + +0:01:18.560,0:01:24.840 +You learn new things. Those things + +0:01:20.799,0:01:27.600 +stick with you. You learn how to + +0:01:27.600,0:01:30.720 +make it do new tricks and then + +0:01:30.720,0:01:36.799 +keep doing those tricks. + +0:01:33.759,0:01:39.439 +I want to mention that this + +0:01:36.799,0:01:41.439 +conference--oops, + +0:01:39.439,0:01:45.600 +this talk isn't about + +0:01:41.439,0:01:47.520 +how to adjust your + +0:01:45.600,0:01:50.000 +configuration specifically. I don't have + +0:01:47.520,0:01:51.520 +a bunch of good code samples in here. + +0:01:50.000,0:01:54.399 +There are other great talks at the + +0:01:51.520,0:01:57.600 +conference, particularly Andrew's, + +0:01:54.399,0:01:59.920 +that I looked at, that looked + +0:01:57.600,0:02:01.600 +like they might be more aimed at that + +0:01:59.920,0:02:02.240 +"hey, I'm just getting started with Emacs, + +0:02:02.240,0:02:07.200 +what are some things to try to make + +0:02:05.280,0:02:08.879 +it more comfortable for me starting?" This + +0:02:07.200,0:02:09.759 +is about how to think about the problem + +0:02:08.879,0:02:12.959 +space. + +0:02:09.759,0:02:14.080 +Hopefully, a good warm up as we + +0:02:12.959,0:02:17.200 +start thinking about some of the + +0:02:14.080,0:02:20.000 +lightning talks a little later on. + +0:02:17.200,0:02:22.400 +I'm just gonna quickly make sure I + +0:02:20.000,0:02:24.080 +can see my IRC buffer in case I run into + +0:02:22.400,0:02:25.680 +time. I didn't get my stopwatch started + +0:02:24.080,0:02:29.680 +for this one. + +0:02:25.680,0:02:32.879 +So all right, let's dive in. + +0:02:29.680,0:02:33.840 +We assume that we want to install + +0:02:32.879,0:02:36.560 +packages + +0:02:33.840,0:02:38.319 +and maybe configure some features. This + +0:02:36.560,0:02:39.120 +is particularly from the perspective of + +0:02:38.319,0:02:40.800 +where we're working + +0:02:39.120,0:02:42.160 +with a bunch of people on a team and we + +0:02:40.800,0:02:44.800 +want to get something done. + +0:02:42.160,0:02:46.560 +Some of us probably already have mature + +0:02:44.800,0:02:49.280 +Emacs workflows. + +0:02:46.560,0:02:50.319 +Others are installing it for the first + +0:02:49.280,0:02:53.519 +time. + +0:02:53.519,0:02:59.280 +So the first question is, you know, + +0:02:56.879,0:03:00.879 +in that context: what's the value + +0:02:59.280,0:03:02.840 +proposition? Why should I mess with my + +0:03:00.879,0:03:05.599 +machine, my mature Emacs + +0:03:02.840,0:03:07.440 +configuration, and impose my + +0:03:05.599,0:03:10.239 +ideas over the way somebody else is + +0:03:07.440,0:03:12.800 +learning Emacs? Well, + +0:03:10.239,0:03:13.840 +it can be.. I'm off my slides here a + +0:03:12.800,0:03:16.400 +little bit. + +0:03:13.840,0:03:16.959 +It can be a little bit + +0:03:16.400,0:03:20.400 +tricky + +0:03:16.959,0:03:21.440 +to learn Emacs. One thing that + +0:03:20.400,0:03:24.720 +helps us a lot + +0:03:21.440,0:03:26.239 +is if people that we're working with + +0:03:24.720,0:03:28.080 +can tell us, kinda, keystroke for + +0:03:26.239,0:03:30.480 +keystroke at times, what to do and + +0:03:28.080,0:03:32.400 +explain what everything is doing. + +0:03:30.480,0:03:35.840 +Using the same packages can really + +0:03:32.400,0:03:39.840 +help us working together on a project. + +0:03:35.840,0:03:40.720 +Speaking from my personal + +0:03:39.840,0:03:42.959 +experience, + +0:03:40.720,0:03:45.040 +it took me decades to get to the point + +0:03:42.959,0:03:46.720 +where I was excited to program in Emacs + +0:03:45.040,0:03:47.840 +Lisp. I've programmed in a lot of programming + +0:03:46.720,0:03:51.200 +languages, + +0:03:47.840,0:03:53.680 +but Lisp wasn't on my list. I looked at + +0:03:51.200,0:03:56.319 +my config that I was copy-pasting around + +0:03:53.680,0:03:57.519 +from generation after generation of + +0:03:56.319,0:03:59.519 +.emacs file or + +0:03:57.519,0:04:00.799 +recrafting it from hand and from Internet + +0:03:59.519,0:04:03.519 +searches, + +0:04:00.799,0:04:05.680 +to get the things that I needed when + +0:04:03.519,0:04:07.680 +I would quickly go install Emacs at some + +0:04:05.680,0:04:10.959 +new job or contract, + +0:04:07.680,0:04:13.680 +and + +0:04:10.959,0:04:15.280 +be able to to quickly get through that + +0:04:13.680,0:04:17.440 +workflow that caused me to install the + +0:04:15.280,0:04:20.560 +program. + +0:04:17.440,0:04:23.440 +You know, just + +0:04:20.560,0:04:25.199 +little simple one-liners that that + +0:04:23.440,0:04:27.120 +got committed to memory over decades + +0:04:25.199,0:04:28.880 +eventually just led me to a sort of "hey what's going on + +0:04:27.120,0:04:31.680 +here." And I credit + +0:04:28.880,0:04:33.520 +Jeff Goff, my good friend who died + +0:04:31.680,0:04:37.759 +earlier in 2020, + +0:04:33.520,0:04:39.280 +for my lifelong love of Emacs. + +0:04:37.759,0:04:40.800 +Perhaps EriK and I will talk about that + +0:04:39.280,0:04:41.360 +a little bit more in another talk we + +0:04:40.800,0:04:43.280 +have + +0:04:41.360,0:04:44.400 +scheduled, but Jeff was a huge + +0:04:43.280,0:04:47.280 +influenceo on us + +0:04:44.400,0:04:48.720 +in a number of ways and a huge + +0:04:47.280,0:04:50.720 +contributor to the Raku programming + +0:04:48.720,0:04:54.000 +language + +0:04:50.720,0:04:54.000 +which is very cool. + +0:04:54.840,0:05:01.039 +So, understanding how + +0:04:58.880,0:05:03.120 +to make a good decision about splitting + +0:05:01.039,0:05:03.680 +up configuration in a way to share it + +0:05:03.120,0:05:05.600 +across + +0:05:03.680,0:05:07.600 +people with really different uses of + +0:05:05.600,0:05:09.360 +Emacs... That's actually a + +0:05:07.600,0:05:11.039 +complicated topic and I want to + +0:05:09.360,0:05:12.639 +sort of back off and stare at it for a + +0:05:11.039,0:05:15.840 +second. + +0:05:12.639,0:05:18.720 +I think Emacs is about people, so that + +0:05:15.840,0:05:22.000 +means it's about community. + +0:05:18.720,0:05:24.960 +And community means we're going to + +0:05:22.000,0:05:29.120 +invite disagreement. + +0:05:24.960,0:05:32.160 +In fact, that disagreement + +0:05:29.120,0:05:33.280 +isn't necessarily a road-block to our + +0:05:32.160,0:05:35.680 +project. In fact, + +0:05:33.280,0:05:37.759 +some of the work that a community + +0:05:35.680,0:05:39.680 +project can invite us to do + +0:05:37.759,0:05:40.960 +is to get closer to each other by + +0:05:39.680,0:05:42.080 +inviting those disagreements, by + +0:05:40.960,0:05:43.280 +learning from them--learning from + +0:05:42.080,0:05:46.880 +different people's + +0:05:43.280,0:05:49.120 +styles and from how they argue, + +0:05:46.880,0:05:50.400 +and thinking about why they have that + +0:05:49.120,0:05:53.680 +perspective and + +0:05:50.400,0:05:55.360 +what technical benefits that + +0:05:53.680,0:05:56.720 +perhaps radical point of view might + +0:05:55.360,0:05:59.039 +carry away. Some people are really + +0:05:56.720,0:06:01.919 +aggressive arguers, and others + +0:05:59.039,0:06:03.120 +are very passive and really + +0:06:01.919,0:06:06.240 +couch their ideas + +0:06:03.120,0:06:08.080 +in distancing terms, to say, "well + +0:06:06.240,0:06:12.479 +probably, this is a good idea" or + +0:06:08.080,0:06:15.520 +"please double check me." + +0:06:12.479,0:06:17.120 +Those don't always necessarily indicate + +0:06:15.520,0:06:18.479 +how certain a person is, because we're + +0:06:17.120,0:06:19.520 +different. We have different ways of + +0:06:18.479,0:06:23.380 +communicating + +0:06:19.520,0:06:24.560 +ideas like certainty or excitement. + +0:06:23.380,0:06:26.560 +[Music] + +0:06:24.560,0:06:30.000 +When we think about a bunch of really + +0:06:26.560,0:06:33.280 +diverse programmers approaching Emacs, + +0:06:30.000,0:06:36.479 +probably one of our our first really big + +0:06:33.280,0:06:39.759 +challenges is just + +0:06:36.479,0:06:41.120 +to pick what we're going to go + +0:06:39.759,0:06:44.000 +after.

It's because + +0:12:49.200,0:12:53.920 +it could be, if we cared for it to be. + +0:12:51.440,0:12:55.680 +It's quite a threatening product + +0:12:55.680,0:12:59.440 +from the perspective of how many problem + +0:12:57.440,0:13:01.519 +spaces it can address, how many types of + +0:12:59.440,0:13:04.399 +users it can satisfy, + +0:13:01.519,0:13:05.600 +the things that we can do to make + +0:13:04.399,0:13:07.839 +it robust in those + +0:13:05.600,0:13:09.760 +environments.

make actually occur + +0:01:25.960,0:01:30.720 +[Music] + +0:01:28.479,0:01:33.439 +the other editing paradigm is where we + +0:01:30.720,0:01:36.000 +escape to a higher level + +0:01:33.439,0:01:36.479 +and now the characters that we type are + +0:01:36.000,0:01:39.040 +not + +0:01:36.479,0:01:41.600 +they don't actually appear on the screen + +0:01:39.040,0:01:44.799

+about this + +0:02:05.360,0:02:11.440 +text in terms of these + +0:02:08.800,0:02:13.120 +textual entities and this textual + +0:02:11.440,0:02:15.920 +language + +0:02:13.120,0:02:18.319 +this is

+0:02:30.480,0:02:35.200 +to go back out to the referential level + +0:02:33.200,0:02:37.280 +enter to go down to ground level + +0:02:35.200,0:02:39.599 +and escape to go up to the referential + +0:02:37.280,0:02:39.599 +level + +0:02:40.160,0:02:48.239 +now in vim the nouns + +0:02:44.879,0:02:50.959 +in this world of text all + +0:02:48.239,0:02:51.519 +share the same referential plane which + +0:02:50.959,0:02:54.319 +we call + +0:02:51.519,0:02:54.959 +normal mode so in normal mode all of the + +0:02:54.319,0:02:57.360 +nouns + +0:02:54.959,0:02:58.959 +of the world of text are available + +0:02:57.360,0:03:00.959 +whether it's words or sentences or + +0:02:58.959,0:03:04.400 +paragraphs + +0:03:00.959,0:03:08.319 +and they all share this same + +0:03:04.400,0:03:11.120 +referential plane and there's uh + +0:03:08.319,0:03:12.720 +they sort of compete for space on the + +0:03:11.120,0:03:15.760 +keyboard + +0:03:12.720,0:03:17.680 +um so an alternative uh + +0:03:15.760,0:03:19.280 +way to structure these modes is instead + +0:03:17.680,0:03:21.840 +of having a single mode where all the + +0:03:19.280,0:03:24.959 +nouns coexist + +0:03:21.840,0:03:30.400 +peacefully or otherwise you instead + +0:03:24.959,0:03:33.040 +have a dedicated mode for every noun + +0:03:30.400,0:03:35.440 +so in that case what happens is because + +0:03:33.040,0:03:37.280 +your modal spaces are now much smaller + +0:03:35.440,0:03:38.720 +you're just talking about words or + +0:03:37.280,0:03:42.560 +paragraphs or + +0:03:38.720,0:03:45.760 +lines or something the keys that you use + +0:03:42.560,0:03:48.560 +can be much more targeted + +0:03:45.760,0:03:50.400 +and you can use the same keystrokes in + +0:03:48.560,0:03:52.000 +in all of your modes and they would have + +0:03:50.400,0:03:53.280 +the same ideas behind them but + +0:03:52.000,0:03:55.519 +they would have different effects + +0:03:53.280,0:03:57.519 +depending on which context you're using + +0:03:55.519,0:03:59.120 +so it's the same keystrokes different + +0:03:57.519,0:04:01.360 +contexts + +0:03:59.120,0:04:02.480 +and the advantage of that is it's often + +0:04:01.360,0:04:05.519 +easier + +0:04:02.480,0:04:09.040 +to change context than it is to + +0:04:05.519,0:04:12.080 +learn new key bindings so let's see + +0:04:09.040,0:04:13.680 +an example of how that works we go into + +0:04:12.080,0:04:14.000 +character mode and if you look at the + +0:04:13.680,0:04:15.439 +mode + +0:04:14.000,0:04:18.720 +line at the bottom of the screen there + +0:04:15.439,0:04:21.519 +you'll see that we're in character mode + +0:04:18.720,0:04:23.919 +and now when we move up down left and + +0:04:21.519,0:04:28.479 +right we're moving by character + +0:04:23.919,0:04:30.240 +we can also transform the text and + +0:04:28.479,0:04:32.400 +the transformations occur in terms of + +0:04:30.240,0:04:34.320 +character + +0:04:32.400,0:04:35.520 +you can also go into word mode and in + +0:04:34.320,0:04:38.560 +word mode + +0:04:35.520,0:04:40.000 +the transformations that you do are on + +0:04:38.560,0:04:42.320 +words + +0:04:40.000,0:04:43.440 +and you try you your movement is also in + +0:04:42.320,0:04:45.600 +terms of words + +0:04:43.440,0:04:46.560 +so that's the level of granularity that + +0:04:45.600,0:04:49.520 +you have + +0:04:46.560,0:04:50.720 +you could also go to line mode and when + +0:04:49.520,0:04:53.759 +you're in line mode + +0:04:50.720,0:04:54.240 +you go up and down by line and you can + +0:04:53.759,0:04:57.520 +move + +0:04:54.240,0:04:59.120 +lines up and down left and right and so + +0:04:57.520,0:05:00.880 +on + +0:04:59.120,0:05:02.800 +and the transformations you do are in + +0:05:00.880,0:05:07.600 +terms of lines + +0:05:02.800,0:05:07.600 +you could also go to window mode where + +0:05:08.400,0:05:12.400 +now the objects that you're referring to + +0:05:10.639,0:05:15.759 +are windows and you can + +0:05:12.400,0:05:17.520 +move spatially amongst the windows or + +0:05:15.759,0:05:20.850 +make do transformations on the windows + +0:05:17.520,0:05:22.840 +using the same keystrokes + +0:05:20.850,0:05:25.360 +[Music] + +0:05:22.840,0:05:28.720 +um + +0:05:25.360,0:05:32.800 +so let's go to + +0:05:28.720,0:05:35.280 +um right and so um the one of the things + +0:05:32.800,0:05:36.880 +the the principles that play here is + +0:05:35.280,0:05:38.000 +something called the rumpelstiltskin + +0:05:36.880,0:05:40.720 +principle which is something + +0:05:38.000,0:05:42.320 +that's known in computer science which + +0:05:40.720,0:05:43.759 +is that if you can name something then + +0:05:42.320,0:05:46.720 +you have that you have power + +0:05:43.759,0:05:48.560 +then you have power over it so this is + +0:05:46.720,0:05:50.479 +kind of an adaptation of that principle + +0:05:48.560,0:05:52.320 +which says that if you can + +0:05:50.479,0:05:54.000 +name something and if you can talk about + +0:05:52.320,0:05:55.360 +it then it's a noun + +0:05:54.000,0:05:56.960 +[Music] + +0:05:55.360,0:05:58.960 +in your editing language and if it's a + +0:05:56.960,0:06:01.520 +noun then it has + +0:05:58.960,0:06:02.319 +it's a mode so if we can talk about it + +0:06:01.520,0:06:05.039 +it's a noun + +0:06:02.319,0:06:06.479 +if it's a noun then it's a mode and one + +0:06:05.039,0:06:07.039 +of the things we've been talking a lot + +0:06:06.479,0:06:10.800 +about + +0:06:07.039,0:06:14.240 +is modes so in fact + +0:06:10.800,0:06:17.280 +uh by this principle modes also + +0:06:14.240,0:06:19.039 +should be a mode + +0:06:17.280,0:06:21.120 +you should have a mode that can reason + +0:06:19.039,0:06:22.080 +in terms of modes as objects just like + +0:06:21.120,0:06:23.759 +you have + +0:06:22.080,0:06:26.560 +modes where you can reason in terms of + +0:06:23.759,0:06:28.800 +words or lines as objects + +0:06:26.560,0:06:30.479 +and so let's do that let's go to mode + +0:06:28.800,0:06:34.000 +mode + +0:06:30.479,0:06:36.080 +when you go to mode mode you see that uh + +0:06:34.000,0:06:37.919 +the objects that are depicted here are + +0:06:36.080,0:06:40.960 +the modes that are + +0:06:37.919,0:06:44.880 +that are present in the buffer + +0:06:40.960,0:06:46.400 +which we knew about um because the + +0:06:44.880,0:06:48.720 +style of editing that we had in this + +0:06:46.400,0:06:50.479 +buffer was the vim style of editing + +0:06:48.720,0:06:52.400 +where there's an insert mode at the + +0:06:50.479,0:06:53.039 +ground level and a normal mode that you + +0:06:52.400,0:06:57.280 +can escape + +0:06:53.039,0:07:00.479 +to you insert enter the ground level + +0:06:57.280,0:07:02.880 +enter to the insert mode and escape to + +0:07:00.479,0:07:03.680 +normal mode and when you look at the + +0:07:02.880,0:07:06.160 +mode mode + +0:07:03.680,0:07:09.680 +representation you see that in fact that + +0:07:06.160,0:07:09.680 +is the structure that's depicted + +0:07:10.479,0:07:14.080 +but in different situations you might + +0:07:12.720,0:07:16.080 +find + +0:07:14.080,0:07:17.680 +that you that these modes are not the + +0:07:16.080,0:07:19.360 +ones that you want you want something + +0:07:17.680,0:07:20.880 +more tailored for the specific + +0:07:19.360,0:07:23.050 +application + +0:07:20.880,0:07:24.240 +for instance if you're editing + +0:07:23.050,0:07:27.360 +[Music] + +0:07:24.240,0:07:30.880 +lisp code uh or or code in general but + +0:07:27.360,0:07:32.960 +list code is a particular example + +0:07:30.880,0:07:34.000 +you might want to take advantage of the + +0:07:32.960,0:07:37.599 +structure of + +0:07:34.000,0:07:40.960 +the code and for lisp code in particular + +0:07:37.599,0:07:44.240 +we have a mode called symax mode + +0:07:40.960,0:07:46.720 +which is able to reason + +0:07:44.240,0:07:47.919 +about your code in terms of its tree + +0:07:46.720,0:07:50.560 +structure + +0:07:47.919,0:07:51.120 +so you can use the same keystrokes hkl + +0:07:50.560,0:07:53.440 +goes + +0:07:51.120,0:07:54.960 +left right up and down but you also have + +0:07:53.440,0:07:58.080 +other keystrokes that are more + +0:07:54.960,0:08:01.520 +specialized to the application + +0:07:58.080,0:08:06.160 +and you can run the code and + +0:08:01.520,0:08:06.160 +we'll see that happen here in a minute + +0:08:06.960,0:08:12.240 +and you can make changes to it really + +0:08:10.080,0:08:16.080 +quickly + +0:08:12.240,0:08:16.080 +and see the effects of those changes + +0:08:18.000,0:08:21.360 +and you're doing this all in a mode + +0:08:19.440,0:08:23.199 +that's convenient for + +0:08:21.360,0:08:25.039 +this particular application which is + +0:08:23.199,0:08:28.960 +editing lisp code + +0:08:25.039,0:08:31.039 +and that is in this case symmex mode + +0:08:28.960,0:08:32.640 +so typically when you're editing code + +0:08:31.039,0:08:34.800 +like this you'd want to be + +0:08:32.640,0:08:36.640 +in insert mode actually typing out the + +0:08:34.800,0:08:38.320 +code + +0:08:36.640,0:08:40.959 +and then you'd want to escape to simex + +0:08:38.320,0:08:42.159 +mode rather than normal mode + +0:08:40.959,0:08:44.080 +and then you could escape again and + +0:08:42.159,0:08:46.720 +you'd end up in normal mode + +0:08:44.080,0:08:48.000 +so this if we go to mode mode we see is + +0:08:46.720,0:08:51.040 +depicted + +0:08:48.000,0:08:52.800 +as this tower where insert is at the + +0:08:51.040,0:08:54.800 +bottom and normal is at the top but + +0:08:52.800,0:08:57.200 +symmex mode is in between + +0:08:54.800,0:08:58.800 +the two you could also change that if + +0:08:57.200,0:09:00.640 +you like if you don't want cmx mode to + +0:08:58.800,0:09:03.760 +be there you could just + +0:09:00.640,0:09:05.600 +move it to the top and now you find some + +0:09:03.760,0:09:06.160 +mixes at the top and you enter down to + +0:09:05.600,0:09:07.600 +normal + +0:09:06.160,0:09:10.480 +you can see it on the status bar at the + +0:09:07.600,0:09:13.839 +bottom there enter to insert + +0:09:10.480,0:09:16.480 +escape to normal escape to symmex and + +0:09:13.839,0:09:19.380 +in fact you can even add more modes if + +0:09:16.480,0:09:21.519 +you don't like the existing ones + +0:09:19.380,0:09:23.839 +[Music] + +0:09:21.519,0:09:25.440 +and now we have an additional mode here + +0:09:23.839,0:09:27.519 +we have window mode it goes down to + +0:09:25.440,0:09:30.320 +symmex goes down to normal + +0:09:27.519,0:09:33.600 +enter the insert escape to normal escape + +0:09:30.320,0:09:37.600 +to smx escape the window + +0:09:33.600,0:09:41.760 +um so we've talked okay so another thing + +0:09:37.600,0:09:45.360 +actually to note here is that in editing + +0:09:41.760,0:09:46.720 +modes um + +0:09:45.360,0:09:48.399 +if you look at the mode line at the + +0:09:46.720,0:09:50.640 +bottom of the screen + +0:09:48.399,0:09:51.519 +you'll see that we are currently in this + +0:09:50.640,0:09:54.560 +buffer + +0:09:51.519,0:09:57.600 +we are currently in line mode + +0:09:54.560,0:09:58.720 +and i'm going to hit enter now and + +0:09:57.600,0:10:01.519 +you'll see that when i hit + +0:09:58.720,0:10:02.160 +enter nothing is happening it's still in + +0:10:01.519,0:10:05.120 +line mode + +0:10:02.160,0:10:07.200 +if you'd escape it's still in line mode + +0:10:05.120,0:10:10.640 +and you can find out the reason for that + +0:10:07.200,0:10:12.800 +by taking another meta jump out of this + +0:10:10.640,0:10:15.279 +and you'll see that in fact the reason + +0:10:12.800,0:10:17.360 +is that we're currently in line mode + +0:10:15.279,0:10:19.519 +and line mode is the only one available + +0:10:17.360,0:10:21.760 +in this tower + +0:10:19.519,0:10:24.880 +for editing the modes that are in + +0:10:21.760,0:10:26.560 +operation in your ground level + +0:10:24.880,0:10:28.320 +and in fact line mode is all you need + +0:10:26.560,0:10:30.320 +here because this is just + +0:10:28.320,0:10:32.079 +uh the nature of how these modes are + +0:10:30.320,0:10:35.040 +laid out is + +0:10:32.079,0:10:36.399 +in in rows and so line mode is the most + +0:10:35.040,0:10:37.680 +appropriate thing here + +0:10:36.399,0:10:39.740 +but you could change it to something + +0:10:37.680,0:10:40.959 +else if you like + +0:10:39.740,0:10:44.160 +[Music] + +0:10:40.959,0:10:44.560 +and then now we've seen two towers we've + +0:10:44.160,0:10:48.079 +seen + +0:10:44.560,0:10:53.680 +the vim tower and we've seen + +0:10:48.079,0:10:56.959 +also the symex tower the the lisp tower + +0:10:53.680,0:10:58.880 +and it turns out that because we've been + +0:10:56.959,0:11:01.519 +talking about towers now + +0:10:58.880,0:11:02.800 +by the rumpelstiltskin principle towers + +0:11:01.519,0:11:06.399 +also + +0:11:02.800,0:11:09.279 +um can be talked about + +0:11:06.399,0:11:11.200 +and therefore they also are a mode so + +0:11:09.279,0:11:14.640 +how do we go to tower mode + +0:11:11.200,0:11:18.560 +and the way we go tower mode is we do + +0:11:14.640,0:11:18.560 +we go in a slightly different direction + +0:11:19.200,0:11:23.120 +and we find that we are now in tower + +0:11:20.800,0:11:23.120 +mode + +0:11:23.360,0:11:29.279 +and we see that there are many towers + +0:11:27.440,0:11:32.640 +available so we're now + +0:11:29.279,0:11:36.240 +we're we're seeing several possible + +0:11:32.640,0:11:39.120 +towers that we have written + +0:11:36.240,0:11:41.440 +um to be available and for use in + +0:11:39.120,0:11:44.000 +different buffers and you can edit them + +0:11:41.440,0:11:46.320 +on the fly for instance let's enter this + +0:11:44.000,0:11:46.320 +tower + +0:11:46.630,0:11:49.920 +[Music] + +0:11:48.000,0:11:51.519 +and now you see that in the bottom of + +0:11:49.920,0:11:52.480 +the in the mode line you see that we're + +0:11:51.519,0:11:54.240 +going + +0:11:52.480,0:11:56.480 +across all of these different modes that + +0:11:54.240,0:11:58.800 +were in the tower + +0:11:56.480,0:12:00.399 +and you could escape and you could even + +0:11:58.800,0:12:00.880 +move things around you could put window + +0:12:00.399,0:12:02.399 +mode + +0:12:00.880,0:12:04.079 +all the way at the bottom right above + +0:12:02.399,0:12:06.880 +insert mode + +0:12:04.079,0:12:09.839 +let's see that happen there it is window + +0:12:06.880,0:12:13.040 +is right above insert + +0:12:09.839,0:12:14.240 +so on and the tower always reflects your + +0:12:13.040,0:12:15.760 +current position + +0:12:14.240,0:12:17.600 +so if you're in buffer mode here and you + +0:12:15.760,0:12:19.120 +go down to line mode + +0:12:17.600,0:12:22.240 +when you go back to mode mode you see + +0:12:19.120,0:12:22.240 +that we are in line mode + +0:12:22.480,0:12:26.160 +but in practice you wouldn't have a + +0:12:24.000,0:12:28.959 +tower this elaborate because + +0:12:26.160,0:12:29.440 +you'd rather have several smaller towers + +0:12:28.959,0:12:33.360 +you + +0:12:29.440,0:12:36.639 +enter that you alternate between + +0:12:33.360,0:12:39.839 +um okay so one + +0:12:36.639,0:12:42.240 +other thing of interest here is that + +0:12:39.839,0:12:43.839 +when you're in tower mode + +0:12:42.240,0:12:45.920 +if you look at the status line at the + +0:12:43.839,0:12:49.200 +bottom there we are currently + +0:12:45.920,0:12:49.839 +in buffer mode while we are in tower + +0:12:49.200,0:12:51.600 +mode + +0:12:49.839,0:12:53.519 +and tower mode actually isn't a mode + +0:12:51.600,0:12:53.920 +really neither is mode mode they're + +0:12:53.519,0:12:58.000 +really + +0:12:53.920,0:13:00.959 +referential planes or meta planes + +0:12:58.000,0:13:03.120 +um in any case you can see that we're in + +0:13:00.959,0:13:04.560 +buffer mode and we can take a meta jump + +0:13:03.120,0:13:07.120 +out of this to confirm + +0:13:04.560,0:13:08.000 +that buffer mode is the only mode + +0:13:07.120,0:13:10.560 +available + +0:13:08.000,0:13:11.200 +when we're editing towers because that's + +0:13:10.560,0:13:14.240 +the one + +0:13:11.200,0:13:15.200 +we need given that our towers are + +0:13:14.240,0:13:21.839 +represented + +0:13:15.200,0:13:21.839 +in individual buffers + +0:13:23.200,0:13:26.320 +right so let's uh let's see where we're + +0:13:26.000,0:13:28.240 +at + +0:13:26.320,0:13:30.160 +trump's still skin principle we talked + +0:13:28.240,0:13:32.240 +about mode mode + +0:13:30.160,0:13:33.920 +um we talked about the strange loop + +0:13:32.240,0:13:37.820 +application of + +0:13:33.920,0:13:39.600 +ground level modes in meta levels + +0:13:37.820,0:13:42.240 +[Music] + +0:13:39.600,0:13:43.199 +and yeah we saw the different towers and + +0:13:42.240,0:13:46.639 +in fact + +0:13:43.199,0:13:49.839 +you can we're currently in + +0:13:46.639,0:13:49.839 +vim tower + +0:13:50.720,0:13:54.720 +where you can go to emacs tower and now + +0:13:53.120,0:13:55.760 +with a single keystroke you can + +0:13:54.720,0:13:59.040 +alternate + +0:13:55.760,0:14:02.399 +between e-max + +0:13:59.040,0:14:05.519 +and vim which are represented which are + +0:14:02.399,0:14:07.839 +modeled as towers + +0:14:05.519,0:14:07.839 +um + +0:14:09.279,0:14:11.920 +okay so + +0:14:13.360,0:14:17.040 +so there's uh the one thing that we've + +0:14:15.360,0:14:18.160 +sort of alluded to is that there are two + +0:14:17.040,0:14:20.480 +directions + +0:14:18.160,0:14:22.399 +that you can travel in when you're going + +0:14:20.480,0:14:25.120 +through this framework + +0:14:22.399,0:14:32.560 +one lev one direction is uh and we'll + +0:14:25.120,0:14:32.560 +visualize it with uh like so + +0:14:33.760,0:14:37.040 +there's two directions you can travel + +0:14:35.120,0:14:38.399 +and you can either go sideways or you + +0:14:37.040,0:14:40.399 +can go up and down + +0:14:38.399,0:14:41.680 +if you go sideways you're changing your + +0:14:40.399,0:14:45.440 +perspective + +0:14:41.680,0:14:47.360 +so normal mode word mode line mode + +0:14:45.440,0:14:49.120 +window mode and so on are all different + +0:14:47.360,0:14:51.680 +perspectives on your under on your + +0:14:49.120,0:14:53.040 +ground editing experience + +0:14:51.680,0:14:55.519 +and the other direction you can travel + +0:14:53.040,0:14:57.920 +in is up or down which takes you + +0:14:55.519,0:14:59.600 +through meta levels so you go from the + +0:14:57.920,0:15:01.920 +ground level editing experience + +0:14:59.600,0:15:03.440 +up to mode mode and then up to the tower + +0:15:01.920,0:15:07.040 +plane and so on + +0:15:03.440,0:15:10.800 +or uh yeah and so on + +0:15:07.040,0:15:14.880 +um yeah so this all sounds + +0:15:10.800,0:15:18.160 +very complex but the truth is + +0:15:14.880,0:15:21.519 +it's not really that complicated + +0:15:18.160,0:15:22.959 +even though it feels that way the reason + +0:15:21.519,0:15:26.480 +it isn't that complicated + +0:15:22.959,0:15:28.800 +is because no matter how many levels + +0:15:26.480,0:15:30.160 +up or down you go and no matter where + +0:15:28.800,0:15:32.399 +you are + +0:15:30.160,0:15:34.079 +whether you're in at the ground level + +0:15:32.399,0:15:36.000 +editing the actual text + +0:15:34.079,0:15:37.600 +or whether you're at a meta level some + +0:15:36.000,0:15:39.279 +unknown meta level and you don't know + +0:15:37.600,0:15:42.320 +where you are + +0:15:39.279,0:15:44.399 +no matter where you are the way in which + +0:15:42.320,0:15:47.519 +you interact with it + +0:15:44.399,0:15:52.000 +is the same at every level + +0:15:47.519,0:15:55.440 +and that is the great power of um + +0:15:52.000,0:15:58.720 +this approach is that + +0:15:55.440,0:16:00.880 +all of the different levels um are the + +0:15:58.720,0:16:03.839 +same + +0:16:00.880,0:16:05.759 +and in fact the complexity of the whole + +0:16:03.839,0:16:08.720 +is exactly identical to the + +0:16:05.759,0:16:10.000 +complexity of each part so if you know + +0:16:08.720,0:16:12.959 +how to edit words + +0:16:10.000,0:16:13.440 +in the ground level buffer and you know + +0:16:12.959,0:16:15.839 +how to move + +0:16:13.440,0:16:16.720 +lines around using line mode then you + +0:16:15.839,0:16:19.519 +know how to edit + +0:16:16.720,0:16:22.800 +any aspect of your editing experience at + +0:16:19.519,0:16:23.310 +any level + +0:16:22.800,0:16:26.240 +so + +0:16:23.310,0:16:28.480 +[Music] + +0:16:26.240,0:16:28.480 +um + +0:16:30.079,0:16:33.839 +so this is a pre-release demo this + +0:16:32.000,0:16:36.880 +doesn't exist on melpa +

a 10 + +0:00:06.240,0:00:11.759 +minute time slot at the imax conf + +0:00:08.559,0:00:13.519 +and i will show you a quick uh walk + +0:00:11.759,0:00:17.039 +through my gtd + +0:00:13.519,0:00:19.520 +system in order mode so + +0:00:17.039,0:00:20.640 +let's start with capturing we want to + +0:00:19.520,0:00:24.080 +capture + +0:00:20.640,0:00:27.279 +what we do here so the idea + +0:00:24.080,0:00:29.599 +is i press f6 and i say i want to make a + +0:00:27.279,0:00:33.120 +small project because this video + +0:00:29.599,0:00:35.120 +will be a small project so the thing is + +0:00:33.120,0:00:38.239 +record a video + +0:00:35.120,0:00:42.000 +for imax imx + +0:00:38.239,0:00:45.920 +conf 2020 + +0:00:42.000,0:00:49.360 +video is recorded edited + +0:00:45.920,0:00:52.160 +and uploaded and we can also + +0:00:49.360,0:00:53.680 +set the timeline because we want to + +0:00:52.160,0:00:56.640 +upload it and the time + +0:00:53.680,0:00:59.440 +the deadline for uploads is we know it + +0:00:56.640,0:01:02.719 +already the 14th of november + +0:00:59.440,0:01:03.600 +so let me put this in here see this is + +0:01:02.719,0:01:05.760 +done + +0:01:03.600,0:01:07.600 +and now because it's a project i mean i + +0:01:05.760,0:01:09.280 +could say just one task to record a + +0:01:07.600,0:01:12.159 +video but it's + +0:01:09.280,0:01:27.840 +too much so let's split it down in a few + +0:01:12.159,0:01:27.840 +small tasks so the next one + +0:01:40.400,0:01:46.159 +so you see i've just typed a few + +0:01:43.439,0:01:46.640 +quick tasks we can see them if we look + +0:01:46.159,0:01:49.360 +in the + +0:01:46.640,0:01:49.360 +capture file + +0:01:50.240,0:01:54.479 +so you see there's my project entry and + +0:01:52.399,0:01:56.799 +there are all my tasks and since it's a + +0:01:54.479,0:02:00.240 +project i can now + +0:01:56.799,0:02:02.479 +make it easy i just indent every task by + +0:02:00.240,0:02:02.479 +one + +0:02:05.360,0:02:09.840 +and then + +0:02:14.480,0:02:16.800 +so + +0:02:18.560,0:02:27.360 +okay so you see we have one + +0:02:23.120,0:02:30.080 +project here and this one we refile now + +0:02:27.360,0:02:30.080 +to our + +0:02:34.840,0:02:41.680 +backlog + +0:02:36.160,0:02:41.680 +so if we look in our backlog + +0:02:42.000,0:02:51.840 +you see my project with all the tasks + +0:02:45.599,0:02:51.840 +so now next one + +0:02:52.480,0:02:56.720 +and i pretend now i'm doing a weekly + +0:02:55.040,0:03:00.959 +review + +0:02:56.720,0:03:00.959 +see makes me + +0:03:01.040,0:03:07.120 +and i already did some things and now + +0:03:04.080,0:03:10.319 +the point where i am + +0:03:07.120,0:03:14.319 +is schedule tasks with no date + +0:03:10.319,0:03:14.319 +those are all those tasks so i have a + +0:03:15.200,0:03:19.040 +weekly review help but that says okay + +0:03:17.519,0:03:22.080 +show me everything + +0:03:19.040,0:03:25.280 +that i need to schedule plan + +0:03:22.080,0:03:27.760 +so schedule this class we do + +0:03:25.280,0:03:27.760 +everything + +0:03:30.879,0:03:34.640 +so everything is scheduled now + +0:03:35.040,0:03:42.000 +and we can check off that and so on + +0:03:38.239,0:03:44.959 +we can i have a plan + +0:03:42.000,0:03:46.879 +for every day that's my free plan i + +0:03:44.959,0:03:50.239 +press f6 + +0:03:46.879,0:03:53.439 +and i say pp plan + +0:03:50.239,0:03:57.360 +private things you see there is the + +0:03:53.439,0:04:01.120 +first day 12th of november german + +0:03:57.360,0:04:03.200 +and now i can + +0:04:01.120,0:04:04.239 +look at what i have to do today you see + +0:04:03.200,0:04:07.040 +my my uh + +0:04:04.239,0:04:09.360 +agenda view is very long and i just want + +0:04:07.040,0:04:14.000 +to focus on a few tasks so + +0:04:09.360,0:04:16.720 +i copied them to my + +0:04:14.000,0:04:16.720 +daily plan + +0:04:22.639,0:04:29.919 +i just want to show you so i have a + +0:04:25.680,0:04:33.919 +daily plan for every day and that means + +0:04:29.919,0:04:37.680 +this one is what i see + +0:04:33.919,0:04:41.360 +and this one is gone + +0:04:37.680,0:04:43.600 +so now let's pretend we are working on + +0:04:41.360,0:04:44.960 +the first refine the requirements for + +0:04:43.600,0:04:48.320 +the video + +0:04:44.960,0:04:51.520 +and we had a look and uh okay + +0:04:48.320,0:04:53.520 +i can mark this task as done here + +0:04:51.520,0:04:54.840 +because i knew the requirements the main + +0:04:53.520,0:04:57.759 +ct + +0:04:54.840,0:05:01.199 +done format + +0:04:57.759,0:05:05.199 +is 720p + +0:05:01.199,0:05:09.440 +webm codec + +0:05:05.199,0:05:10.960 +so this one is done and i can mark it + +0:05:09.440,0:05:14.560 +off here + +0:05:10.960,0:05:17.600 +as well so now i have marked it

+0:06:39.039,0:06:44.639 +and then i have a video ready and then + +0:06:42.400,0:06:50.639 +let's pretend i did the upload + +0:06:44.639,0:06:55.280 +as well done radio uploaded + +0:06:50.639,0:06:58.319 +cc so i can say everything now is done + +0:06:55.280,0:06:59.199 +save it so tomorrow i see what i did + +0:06:58.319,0:07:02.560 +yesterday + +0:06:59.199,0:07:06.000 +and

+0:07:12.639,0:07:16.960 +the the final step of my weekly review + +0:07:15.199,0:07:19.199 +if you see the + +0:07:16.960,0:07:21.599 +if you see there's a final step that + +0:07:19.199,0:07:24.160 +says select finish tasks and make a bulk + +0:07:21.599,0:07:26.560 +archive action so if you look at my + +0:07:24.160,0:07:27.440 +uh imax coin thing okay the project is + +0:07:26.560,0:07:31.360 +done as well + +0:07:27.440,0:07:34.880 +project ct done + +0:07:31.360,0:07:38.160 +and then what i can do is now see + +0:07:34.880,0:07:41.680 +a weekly review helper + +0:07:38.160,0:07:44.720 +finish tasks and i could + +0:07:41.680,0:07:48.639 +make a bike + +0:07:44.720,0:07:50.639 +operation that says archive everything + +0:07:48.639,0:07:52.720 +but at the moment i don't need to do + +0:07:50.639,0:07:56.720 +that because we have + +0:07:52.720,0:08:00.080 +a tree structure so it's cxa i have this + +0:07:56.720,0:08:02.800 +task away and the task is done so that's + +0:08:00.080,0:08:06.080 +it that's my system you see from + +0:08:02.800,0:08:08.000 +capturing tasks to scheduling tasks to + +0:08:06.080,0:08:09.759 +putting it on the daily plan + +0:08:08.000,0:08:11.120 +performing it and at the end when + +0:08:09.759,0:08:13.199 +everything is done + +0:08:11.120,0:08:14.879 +and the next weekly review they will go +

on + +0:01:19.680,0:01:23.360 +presentation on gtd because that would + +0:01:22.640,0:01:25.680 +be + +0:01:23.360,0:01:27.920 +well other people have done it better + +0:01:25.680,0:01:30.320 +than

+decide what to do if + +0:01:35.600,0:01:39.119 +it could be actionable or not if it's + +0:01:37.200,0:01:40.799 +actionable it could be a project + +0:01:39.119,0:01:42.159 +or it could be a single action which you + +0:01:40.799,0:01:45.759 +could delegate + +0:01:42.159,0:01:48.079 +or soon or schedule or just do + +0:01:45.759,0:01:49.680 +do it if it's not actionable you could + +0:01:48.079,0:01:51.759 +just throw it away + +0:01:49.680,0:01:53.600 +incubate it for later or move it into + +0:01:51.759,0:01:56.079 +your files + +0:01:53.600,0:01:56.079 +reference + +0:01:57.520,0:02:00.240 +over here + +0:02:01.920,0:02:08.959 +you can see the global bindings + +0:02:05.119,0:02:11.599 +or or gtd those are the the actions that + +0:02:08.959,0:02:12.319 +the functions i have made available this + +0:02:11.599,0:02:14.000 +is + +0:02:12.319,0:02:15.760 +in progress there's more to come some + +0:02:14.000,0:02:17.360 +stuff is probably missing but + +0:02:15.760,0:02:22.400 +it's grown mostly from my own personal + +0:02:17.360,0:02:25.520 +use so far so it doesn't have things + +0:02:22.400,0:02:27.200 +and the bottom right you can see the + +0:02:25.520,0:02:28.560 +agenda + +0:02:27.200,0:02:31.599 +one thing i wanted to do with this + +0:02:28.560,0:02:32.959 +package was leverage org mode as much as + +0:02:31.599,0:02:36.319 +possible + +0:02:32.959,0:02:40.160 +so i tried to not reinvent + +0:02:36.319,0:02:43.599 +the wheel as much as i could that meant + +0:02:40.160,0:02:45.599 +reusing the agenda you can see here + +0:02:43.599,0:02:47.920 +a couple of the things that are made + +0:02:45.599,0:02:49.760 +available or kind of + +0:02:47.920,0:02:54.160 +custom customized or configure it for + +0:02:49.760,0:02:54.160 +you some of the opinions that or gtd has + +0:02:54.319,0:02:57.840 +up here for instance you can see a + +0:02:56.400,0:03:01.040 +delegated action + +0:02:57.840,0:03:03.200 +so a delegated action is + +0:03:01.040,0:03:04.720 +as someone to whom it's delegated it's + +0:03:03.200,0:03:06.080 +my parents in this case + +0:03:04.720,0:03:08.239 +it has the name of the action ask + +0:03:06.080,0:03:11.599 +parents what gift they want + +0:03:08.239,0:03:14.800 +it's marked as the tag as the state + +0:03:11.599,0:03:17.280 +of wait because i'm waiting + +0:03:14.800,0:03:18.080 +and it is scheduled because you should + +0:03:17.280,0:03:20.239 +ping people + +0:03:18.080,0:03:21.840 +or check on the status status of a task + +0:03:20.239,0:03:25.680 +when you're waiting for it so you don't + +0:03:21.840,0:03:27.599 +forget about it or it gets lost forever + +0:03:25.680,0:03:30.560 +i have a scheduled action to give a talk + +0:03:27.599,0:03:33.440 +that's what i'm doing right now + +0:03:30.560,0:03:35.599 +and i have an incubated action which is + +0:03:33.440,0:03:36.640 +also scheduled to make money through the + +0:03:35.599,0:03:38.640 +lottery this is a + +0:03:36.640,0:03:41.120 +thing to take a look at for you know + +0:03:38.640,0:03:42.560 +later decide later what i want to do + +0:03:41.120,0:03:44.560 +it might be actionable it might not be i + +0:03:42.560,0:03:46.239 +just i don't know right now or i didn't + +0:03:44.560,0:03:49.280 +know when i + +0:03:46.239,0:03:52.319 +processed it so i incubated it + +0:03:49.280,0:03:53.200 +underneath we have all the things that + +0:03:52.319,0:03:56.799 +are + +0:03:53.200,0:03:56.799 +direct actions for me to take + +0:03:59.360,0:04:03.200 +all right you see a little bit of the + +0:04:01.439,0:04:04.080 +preparation seeps through the actual + +0:04:03.200,0:04:05.519 +talk + +0:04:04.080,0:04:07.920 +so i have here two i have a single + +0:04:05.519,0:04:09.840 +action of a steal the android uh andreas + +0:04:07.920,0:04:12.879 +gtd configuration + +0:04:09.840,0:04:15.840 +and an action to read the gtd book it's + +0:04:12.879,0:04:15.840 +part of a project + +0:04:16.320,0:04:23.840 +so most of the day-to-day operation with + +0:04:21.680,0:04:26.000 +with this package should come through + +0:04:23.840,0:04:29.600 +just having the agenda open + +0:04:26.000,0:04:31.199 +and having having it be your your source + +0:04:29.600,0:04:31.919 +for the information you need to know so + +0:04:31.199,0:04:34.960 +that you can + +0:04:31.919,0:04:35.440 +do the right thing so let's take a look + +0:04:34.960,0:04:37.440 +at + +0:04:35.440,0:04:39.600 +what's underneath all of this really + +0:04:37.440,0:04:42.320 +quickly + +0:04:39.600,0:04:43.360 +we have there's three primary files um + +0:04:42.320,0:04:45.759 +we have the inbox + +0:04:43.360,0:04:46.400 +i'm gonna process it in a second because + +0:04:45.759,0:04:48.880 +there's + +0:04:46.400,0:04:50.000 +two things here one thing to cancel like + +0:04:48.880,0:04:51.919 +an action to + +0:04:50.000,0:04:53.919 +not take it's nothing and then something + +0:04:51.919,0:04:54.479 +i will just put into org roam just so + +0:04:53.919,0:04:58.960 +you can + +0:04:54.479,0:05:00.240 +see that there is the incubate file + +0:04:58.960,0:05:02.000 +you can see here make money through the + +0:05:00.240,0:05:04.800 +lottery + +0:05:02.000,0:05:06.560 +captured refiled here and scheduled to + +0:05:04.800,0:05:10.000 +so it would show up in the agenda + +0:05:06.560,0:05:13.039 +right at a given time and on the right + +0:05:10.000,0:05:14.560 +you have the actionable file and this is + +0:05:13.039,0:05:15.919 +the one that has the most information + +0:05:14.560,0:05:18.960 +because + +0:05:15.919,0:05:20.560 +where most things should go so + +0:05:18.960,0:05:22.720 +i have the single actions they all go + +0:05:20.560,0:05:24.479 +underneath here and so + +0:05:22.720,0:05:26.240 +this is marked as next because it's an + +0:05:24.479,0:05:28.240 +action for me to take + +0:05:26.240,0:05:29.600 +uh delegated is marked as weight it is + +0:05:28.240,0:05:31.199 +not an action for me to take it's an + +0:05:29.600,0:05:32.400 +action for somebody else to take but it + +0:05:31.199,0:05:37.919 +is scheduled because + +0:05:32.400,0:05:38.400 +i may wanna i can check in at some point + +0:05:37.919,0:05:39.759 +uh + +0:05:38.400,0:05:43.120 +things that are scheduled like give a + +0:05:39.759,0:05:44.960 +talk do not have a to-do or next or wait + +0:05:43.120,0:05:46.400 +state because they are not bound that + +0:05:44.960,0:05:48.080 +way they are time-bound + +0:05:46.400,0:05:50.320 +so they will show up in the agenda when + +0:05:48.080,0:05:53.840 +the time comes i shouldn't act on them + +0:05:50.320,0:05:55.280 +or i can't act on them beforehand + +0:05:53.840,0:05:56.880 +you can see here i have two projects a + +0:05:55.280,0:05:58.880 +test project and i will + +0:05:56.880,0:06:00.080 +do something with this in a second and + +0:05:58.880,0:06:01.919 +then there's this + +0:06:00.080,0:06:04.000 +package make a gte package there's a + +0:06:01.919,0:06:07.520 +project here for me to create this back + +0:06:04.000,0:06:09.759 +it's made a bunch of actions and + +0:06:07.520,0:06:11.440 +i'm going to show you two things here + +0:06:09.759,0:06:14.639 +one is + +0:06:11.440,0:06:16.400 +since i was trying to leverage org mode + +0:06:14.639,0:06:20.479 +as much as possible + +0:06:16.400,0:06:24.080 +i didn't try to create very clever + +0:06:20.479,0:06:27.199 +operations because org mode has a lot of + +0:06:24.080,0:06:29.600 +very powerful tools already + +0:06:27.199,0:06:31.039 +so there's automations i could i can add + +0:06:29.600,0:06:34.240 +but i thought it might be + +0:06:31.039,0:06:35.680 +better to leave more things into the + +0:06:34.240,0:06:38.000 +hands of the user + +0:06:35.680,0:06:39.199 +so here in this case this test project + +0:06:38.000,0:06:42.479 +we can just archive + +0:06:39.199,0:06:45.680 +right that's just + +0:06:42.479,0:06:46.840 +control c control x control a is the org + +0:06:45.680,0:06:51.440 +archive + +0:06:46.840,0:06:51.440 +action save this + +0:06:52.000,0:06:56.160 +so now if i if we go to the you know + +0:06:54.479,0:06:59.440 +this will create an archive file + +0:06:56.160,0:07:00.560 +which will have this this information + +0:06:59.440,0:07:03.840 +for later perusal + +0:07:00.560,0:07:05.360 +brutal if you're interested that's + +0:07:03.840,0:07:07.199 +that's one thing if we go back to the + +0:07:05.360,0:07:10.479 +agenda for a second + +0:07:07.199,0:07:14.080 +um you can see + +0:07:10.479,0:07:16.479 +these things here uh org so by the way + +0:07:14.080,0:07:19.120 +uh this this parents here with the org + +0:07:16.479,0:07:22.319 +agenda property this is what shows here + +0:07:19.120,0:07:23.680 +right and here if i finish read the gtd + +0:07:22.319,0:07:27.680 +book + +0:07:23.680,0:07:31.919 +i mark it as done now refresh + +0:07:27.680,0:07:34.720 +you'll see that another item shows up + +0:07:31.919,0:07:37.280 +and that is where org edna comes in when + +0:07:34.720,0:07:39.759 +an action is marked as done in a project + +0:07:37.280,0:07:41.360 +the net the next to do action is + +0:07:39.759,0:07:43.759 +automatically marked as next so your + +0:07:41.360,0:07:46.400 +agenda is automatically updated + +0:07:43.759,0:07:48.400 +this was one of the nice things for me + +0:07:46.400,0:07:50.400 +because i didn't want to have to + +0:07:48.400,0:07:51.919 +open my file go find the action mark it + +0:07:50.400,0:07:53.440 +as done find the next one mark it as + +0:07:51.919,0:07:57.280 +next and so forth + +0:07:53.440,0:07:58.960 +so i didn't want to bother with it + +0:07:57.280,0:08:00.960 +um oh actually you know what let me show + +0:07:58.960,0:08:04.080 +you something else + +0:08:00.960,0:08:07.120 +this uh simple + +0:08:04.080,0:08:07.840 +project i don't need this timestamp to + +0:08:07.120,0:08:09.680 +be here but + +0:08:07.840,0:08:13.039 +i like having a capture timestamp here + +0:08:09.680,0:08:15.919 +so i'm gonna make one up + +0:08:13.039,0:08:16.879 +so this is the most convenient thing + +0:08:15.919,0:08:17.919 +that i think + +0:08:16.879,0:08:20.720 +this is one of the most convenient + +0:08:17.919,0:08:22.960 +things that i get out of is binding + +0:08:20.720,0:08:24.400 +the next really convenient thing is the + +0:08:22.960,0:08:27.440 +way this gets processed + +0:08:24.400,0:08:30.080 +let me show you this um + +0:08:27.440,0:08:31.440 +when you process the the entire inbox + +0:08:30.080,0:08:33.440 +what you see is + +0:08:31.440,0:08:34.560 +the items one at a time so you can work + +0:08:33.440,0:08:36.320 +with them + +0:08:34.560,0:08:38.320 +you can see at the bottom where you can + +0:08:36.320,0:08:40.320 +work with them without being distracted + +0:08:38.320,0:08:42.399 +you can see at the bottom the the list + +0:08:40.320,0:08:45.120 +of things you can do which are all the + +0:08:42.399,0:08:45.760 +decisions you can take from gtd right in + +0:08:45.120,0:08:48.959 +this case + +0:08:45.760,0:08:50.959 +this is one to throw out so press t you + +0:08:48.959,0:08:52.320 +have the option to make modifications to + +0:08:50.959,0:08:55.200 +this if you want to + +0:08:52.320,0:08:56.240 +if you have any reason to store it then + +0:08:55.200,0:08:58.160 +you finish editing + +0:08:56.240,0:09:00.080 +you can add a tag if you want to because + +0:08:58.160,0:09:02.720 +this might still be interesting + +0:09:00.080,0:09:03.920 +and then enter and it's done so + +0:09:02.720,0:09:06.959 +important knowledge + +0:09:03.920,0:09:10.880 +i'm going to hit a for archive it + +0:09:06.959,0:09:12.160 +and then um i'm gonna start looking at + +0:09:10.880,0:09:17.839 +orgrom + +0:09:12.160,0:09:17.839 +so this is uh important knowledge + +0:09:20.800,0:09:24.640 +i have to get to this that's it i've + +0:09:23.519,0:09:27.920 +captured it + +0:09:24.640,0:09:30.959 +uh it is done i uh + +0:09:27.920,0:09:34.080 +go back to buffer + +0:09:30.959,0:09:35.360 +and i can market control c then + +0:09:34.080,0:09:37.279 +there's no archiving because this is + +0:09:35.360,0:09:38.800 +just knowledge there's no + +0:09:37.279,0:09:40.320 +tagging it's just knowledge but then the + +0:09:38.800,0:09:41.040 +simple project i want to show you this + +0:09:40.320,0:09:42.800 +because + +0:09:41.040,0:09:44.640 +there's some automation that's pretty + +0:09:42.800,0:09:48.839 +helpful so + +0:09:44.640,0:09:50.000 +in the simple project i have my first + +0:09:48.839,0:09:53.920 +action + +0:09:50.000,0:09:55.360 +second action third action + +0:09:53.920,0:09:56.720 +and you see this is all i'm writing i'm + +0:09:55.360,0:10:00.000 +not adding any of the states any of the + +0:09:56.720,0:10:00.000 +tags they're going to be added by + +0:10:00.399,0:10:05.839 +so um here i can add a + +0:10:04.320,0:10:07.360 +i can add a tag if i want to this + +0:10:05.839,0:10:09.920 +project i don't care + +0:10:07.360,0:10:11.279 +right now but you know i leave the tags + +0:10:09.920,0:10:11.920 +to the user so they're not super + +0:10:11.279,0:10:15.440 +relevant + +0:10:11.920,0:10:19.279 +to me as a package + +0:10:15.440,0:10:19.600 +provider and this is where we are this + +0:10:19.279,0:10:21.200 +is + +0:10:19.600,0:10:23.519 +the whole thing so now if we go back to + +0:10:21.200,0:10:27.600 +the agenda + +0:10:23.519,0:10:30.720 +i have a first action right and + +0:10:27.600,0:10:32.959 +if i go to the actionable file and now + +0:10:30.720,0:10:34.079 +see i have a simple project that has my + +0:10:32.959,0:10:36.880 +first action as next + +0:10:34.079,0:10:38.079 +second option to do third action as to + +0:10:36.880,0:10:41.360 +do + +0:10:38.079,0:10:42.880 +uh so what i've you know + +0:10:41.360,0:10:47.200 +as you can see i hope what i've tried to + +0:10:42.880,0:10:50.880 +do is take all of the kind of + +0:10:47.200,0:10:52.560 +all the tedium out of working with + +0:10:50.880,0:10:54.880 +with emacs and org mode when working + +0:10:52.560,0:10:57.200 +with your actions so you could focus on + +0:10:54.880,0:10:58.640 +what you want to do what you need to do + +0:10:57.200,0:10:59.279 +what you care about and the package + +0:10:58.640,0:11:04.079 +would + +0:10:59.279,0:11:04.079 +take care of the rest so + +0:11:04.880,0:11:08.000 +the last thing i wanted to take a quick + +0:11:06.240,0:11:08.640 +look at was some of the the tests + +0:11:08.000,0:11:11.120 +there's + +0:11:08.640,0:11:13.440 +the code is available here but you can + +0:11:11.120,0:11:14.800 +see the code + +0:11:13.440,0:11:16.880 +you on see the code on github if you + +0:11:14.800,0:11:18.720 +want um + +0:11:16.880,0:11:20.320 +i've had some trouble writing good tests + +0:11:18.720,0:11:22.000 +for this because org mode was written at + +0:11:20.320,0:11:26.000 +a time before + +0:11:22.000,0:11:29.200 +testing was quite as important + +0:11:26.000,0:11:31.440 +i think or valued quite the same way + +0:11:29.200,0:11:34.320 +let's put it this way + +0:11:31.440,0:11:34.959 +and as a result a number of things + +0:11:34.320,0:11:37.200 +actually + +0:11:34.959,0:11:38.240 +it might also be a feature of emacs at + +0:11:37.200,0:11:40.560 +the time i don't know + +0:11:38.240,0:11:42.480 +but a lot of things in order mode aren't + +0:11:40.560,0:11:45.519 +very testable and so + +0:11:42.480,0:11:49.440 +what i ended up doing was just having an + +0:11:45.519,0:11:53.360 +actual directory in which i + +0:11:49.440,0:11:55.279 +actually um with files + +0:11:53.360,0:11:57.120 +right so like i don't have much mocking + +0:11:55.279,0:11:58.639 +i can do i can't just do a bunch of fake + +0:11:57.120,0:12:01.200 +files fake directories + +0:11:58.639,0:12:03.360 +so i actually go through the process + +0:12:01.200,0:12:05.040 +actually create files and then actually + +0:12:03.360,0:12:08.839 +have emacs pointing at this + +0:12:05.040,0:12:10.240 +directory to process and get the + +0:12:08.839,0:12:12.240 +information + +0:12:10.240,0:12:13.920 +so i have to define the key to test that + +0:12:12.240,0:12:18.160 +gets bounded properly + +0:12:13.920,0:12:19.839 +i have to set the capture templates um + +0:12:18.160,0:12:21.839 +other capture templates are how you know + +0:12:19.839,0:12:25.600 +things get added i have a wrapper + +0:12:21.839,0:12:27.279 +control uh or gtd capture essentially is + +0:12:25.600,0:12:29.920 +a wrapper around the capture that + +0:12:27.279,0:12:32.000 +makes sure the inbox is there and then + +0:12:29.920,0:12:35.920 +captures to the inbox + +0:12:32.000,0:12:35.920 +right and + +0:12:36.240,0:12:41.519 +making sure the items show in the agenda + +0:12:39.360,0:12:42.639 +when i'm done with the with processing + +0:12:41.519,0:12:45.519 +was a little bit + +0:12:42.639,0:12:46.800 +tricky i had a bug and i had to to fix + +0:12:45.519,0:12:49.600 +it so i just wrote this + +0:12:46.800,0:12:50.480 +this test but it's uh it's pretty + +0:12:49.600,0:12:51.839 +convenient + +0:12:50.480,0:12:54.000 +now to have that because it gives me a + +0:12:51.839,0:12:55.040 +bunch of sanity so again i have a + +0:12:54.000,0:12:56.000 +capture and this is + +0:12:55.040,0:12:58.480 +i wanted to be able to do this + +0:12:56.000,0:12:59.680 +automatically but ojtd but or capture + +0:12:58.480,0:13:02.079 +itself + +0:12:59.680,0:13:03.200 +is not super testable right now so the + +0:13:02.079,0:13:04.480 +way it's + +0:13:03.200,0:13:07.519 +the way you test it is just by + +0:13:04.480,0:13:09.279 +programmatically calling it which + +0:13:07.519,0:13:10.639 +is not exactly what i wanted because i + +0:13:09.279,0:13:13.200 +wanted something more like + +0:13:10.639,0:13:15.519 +the user action but i'll you know what i + +0:13:13.200,0:13:17.040 +can get + +0:13:15.519,0:13:19.360 +and then i can i'll just insert these + +0:13:17.040,0:13:21.760 +words into the buffer and then + +0:13:19.360,0:13:23.519 +i'll finalize the capture then i have + +0:13:21.760,0:13:26.160 +another i have a test package here + +0:13:23.519,0:13:29.920 +called with simulated input which + +0:13:26.160,0:13:33.040 +um basically calls this and then enters + +0:13:29.920,0:13:34.800 +these uh these user actions right so + +0:13:33.040,0:13:39.040 +like the letter s + +0:13:34.800,0:13:41.360 +control c c and then return and that is + +0:13:39.040,0:13:42.480 +uh you know choosing a single action + +0:13:41.360,0:13:45.360 +then finishing the edit + +0:13:42.480,0:13:46.480 +and then adding zero and not adding tags + +0:13:45.360,0:13:48.639 +you + +0:13:46.480,0:13:50.320 +as you can tell there's a strong layer + +0:13:48.639,0:13:53.760 +of disconnect between the tests + +0:13:50.320,0:13:56.160 +and what they represent that's a work in + +0:13:53.760,0:13:56.160 +progress + +0:13:56.560,0:14:02.320 +um so i have like four tests + +0:13:59.680,0:14:03.680 +it's not a lot but i want to i intend to + +0:14:02.320,0:14:05.040 +add more as i keep on adding more + +0:14:03.680,0:14:09.519 +behavior + +0:14:05.040,0:14:13.680 +and i would like this to be eventually + +0:14:09.519,0:14:13.680 +a sane starting point for gt + +0:14:14.320,0:14:18.720 +there's there's a lot of people like + +0:14:16.079,0:14:20.959 +like andre i like reiner like + +0:14:18.720,0:14:22.160 +i mean if you search for org mode and + +0:14:20.959,0:14:25.279 +gtd you'll find + +0:14:22.160,0:14:27.600 +a lot of blog entries a lot of + +0:14:25.279,0:14:29.360 +entries a lot of articles that explain + +0:14:27.600,0:14:31.199 +how to connect it together how to think + +0:14:29.360,0:14:34.320 +that way how to use all the tools that + +0:14:31.199,0:14:34.320 +orgmod makes available + +0:14:34.880,0:14:40.320 +and hopefully this package is a way to + +0:14:38.399,0:14:41.040 +get started without having to write too + +0:14:40.320,0:14:45.839 +much + +0:14:41.040,0:14:45.839 +of your own code um + +0:14:45.920,0:14:48.720 +then eventually you can move away from + +0:14:47.279,0:14:50.000 +the package if you want if you realize + +0:14:48.720,0:14:52.000 +that you are developing different + +0:14:50.000,0:14:54.160 +opinions and you don't want to + +0:14:52.000,0:14:55.519 +if gtd doesn't work this way for you if + +0:14:54.160,0:14:57.839 +you have a different way + +0:14:55.519,0:14:59.279 +it is a better fit for the way you want + +0:14:57.839,0:15:02.720 +to organize your life + +0:14:59.279,0:15:05.920

right so you are now muted okay good + +0:00:22.720,0:00:26.960 +to go now so + +0:00:24.160,0:00:28.240 +hello again everyone so i hope you had + +0:00:26.960,0:00:30.880 +well quite a lot of talks + +0:00:28.240,0:00:32.000 +ever since the last one i did and all + +0:00:30.880,0:00:35.040 +more interesting + +0:00:32.000,0:00:36.559 +uh one after the other so um + +0:00:35.040,0:00:38.239 +you know i'm a bit in a bit of a weird + +0:00:36.559,0:00:39.760 +spot right now because i'm supposed to + +0:00:38.239,0:00:40.239 +be presenting to you as you can see on + +0:00:39.760,0:00:42.879 +my screen + +0:00:40.239,0:00:44.960 +one big-ass awk file multiple tiny ones + +0:00:42.879,0:00:48.160 +finally the end of the debate + +0:00:44.960,0:00:49.760 +and it sounds about as clickbaity + +0:00:48.160,0:00:51.280 +as you can possibly get with those + +0:00:49.760,0:00:54.000 +topics and by the way + +0:00:51.280,0:00:55.760 +uh credit where credit is due the title + +0:00:54.000,0:00:57.039 +is not mine it's actually from bastian + +0:00:55.760,0:01:00.719 +gary the current old + +0:00:57.039,0:01:03.199 +maintainer and yeah i wanted to + +0:01:00.719,0:01:04.879 +talk to you a little bit today about + +0:01:03.199,0:01:07.600 +this question because + +0:01:04.879,0:01:09.040 +if you are used to going on our slash + +0:01:07.600,0:01:09.600 +emacs you know the subreddit that we + +0:01:09.040,0:01:11.840 +have + +0:01:09.600,0:01:13.200 +if you go on i can use often you know + +0:01:11.840,0:01:16.000 +it's a question that + +0:01:13.200,0:01:17.520 +you see pop-up every once in a while + +0:01:16.000,0:01:20.640 +should i be using + +0:01:17.520,0:01:24.159 +one big file or should i be using + +0:01:20.640,0:01:24.799 +a lot of tiny files and i believe you + +0:01:24.159,0:01:27.600 +know + +0:01:24.799,0:01:29.520 +we've got defenders on both sides if i + +0:01:27.600,0:01:32.479 +just show you one examples + +0:01:29.520,0:01:35.280 +so we have carl voigt okay so he's one + +0:01:32.479,0:01:37.920 +of the organizers for the conference + +0:01:35.280,0:01:40.000 +he hears the guy who probably has the + +0:01:37.920,0:01:42.000 +biggest augment files + +0:01:40.000,0:01:43.759 +right now in all the people i know and + +0:01:42.000,0:01:44.479 +god knows i know plenty of people use + +0:01:43.759,0:01:46.880 +old mode + +0:01:44.479,0:01:48.320 +but if you just look at this line i hope + +0:01:46.880,0:01:51.360 +it's not too small you just + +0:01:48.320,0:01:56.719 +make it a little larger but + +0:01:51.360,0:02:01.759 +carl basically has a file with 126 + +0:01:56.719,0:02:04.560 +000 lines and i'm just going to pause + +0:02:01.759,0:02:06.399 +and try to have you imagine how large a + +0:02:04.560,0:02:08.399 +file it actually is + +0:02:06.399,0:02:10.000 +just think about all of these lines + +0:02:08.399,0:02:12.080 +being tasked in your days + +0:02:10.000,0:02:13.200 +think about all those lines being about + +0:02:12.080,0:02:14.400 +little thoughts + +0:02:13.200,0:02:17.200 +you know that you've had throughout the + +0:02:14.400,0:02:19.680 +day or project that you were working on + +0:02:17.200,0:02:20.720 +and it's massive and you know one of the + +0:02:19.680,0:02:23.920 +problem that + +0:02:20.720,0:02:27.680 +uh calvoit actually approaches on + +0:02:23.920,0:02:30.160 +this topic is that it takes him roughly + +0:02:27.680,0:02:32.400 +20 seconds to get his old agenda going + +0:02:30.160,0:02:35.680 +which is a massive amount of time + +0:02:32.400,0:02:37.720 +i mean we have very fast computers now + +0:02:35.680,0:02:39.200 +you know ever since e-max was created in + +0:02:37.720,0:02:42.319 +1976 + +0:02:39.200,0:02:43.440 +computers i have no idea how much faster + +0:02:42.319,0:02:47.760 +they've gotten + +0:02:43.440,0:02:49.599 +and yet you know for earth 1000 lines + +0:02:47.760,0:02:51.120 +emac seems to be choking and it's + +0:02:49.599,0:02:52.720 +certainly not reasonable in a way to + +0:02:51.120,0:02:55.360 +have to wait 20 seconds + +0:02:52.720,0:02:57.040 +just for your entire file to be passed + +0:02:55.360,0:02:58.480 +so basically what i want to do + +0:02:57.040,0:03:00.879 +and by the way i forgot to do the + +0:02:58.480,0:03:02.879 +presentation but i'm leova i did this + +0:03:00.879,0:03:05.519 +before for those who were around + +0:03:02.879,0:03:06.640 +and i um help maintain a software which + +0:03:05.519,0:03:08.560 +is called orgrom + +0:03:06.640,0:03:09.840 +and that's the expertise that i have on + +0:03:08.560,0:03:11.760 +the topic + +0:03:09.840,0:03:13.599 +actually if you go online i do have a + +0:03:11.760,0:03:15.440 +github page i will make sure that you + +0:03:13.599,0:03:18.640 +have all the links available afterwards + +0:03:15.440,0:03:20.720 +but i do publish my init files + +0:03:18.640,0:03:22.319 +and you can see if you scroll at the + +0:03:20.720,0:03:23.200 +bottom i have a little demonstration + +0:03:22.319,0:03:25.519 +which shows you + +0:03:23.200,0:03:27.440 +the fancy things that i can do with my + +0:03:25.519,0:03:28.159 +old mood setup and that might be even + +0:03:27.440,0:03:30.720 +interesting + +0:03:28.159,0:03:32.319 +in lights of the talk you've just had + +0:03:30.720,0:03:34.080 +about gtd stuff because + +0:03:32.319,0:03:36.159 +the first one is about how i end all my + +0:03:34.080,0:03:39.680 +projects the second one is about + +0:03:36.159,0:03:40.000 +the flow from a task uh as i work on it + +0:03:39.680,0:03:41.519 +so + +0:03:40.000,0:03:43.120 +i won't spend too much time on this but + +0:03:41.519,0:03:45.440 +basically that's my expertise + +0:03:43.120,0:03:46.959 +i have spent eight years working with + +0:03:45.440,0:03:48.959 +working with org mode + +0:03:46.959,0:03:50.720 +three of them actually thinking about + +0:03:48.959,0:03:54.080 +writing packages + +0:03:50.720,0:03:55.680 +and the thing is if i go into a little + +0:03:54.080,0:03:57.760 +bit of details and obviously it's only a + +0:03:55.680,0:04:00.720 +lighting talk so i won't have time to + +0:03:57.760,0:04:01.840 +actually go really in depth about it but + +0:04:00.720,0:04:03.599 +there is something + +0:04:01.840,0:04:05.200 +in the ultimate libraries which is + +0:04:03.599,0:04:07.000 +called org elements + +0:04:05.200,0:04:08.319 +and you have the name right there org + +0:04:07.000,0:04:11.439 +element.el + +0:04:08.319,0:04:12.319 +dot el being for e-lisp file and as you + +0:04:11.439,0:04:14.799 +can see + +0:04:12.319,0:04:16.239 +the page it's on the work wiki so it's + +0:04:14.799,0:04:19.280 +accessible by everyone + +0:04:16.239,0:04:23.759 +but it's basically the api that + +0:04:19.280,0:04:26.400 +org mode uses to pass all mode files + +0:04:23.759,0:04:27.199 +so for those who don't know passing + +0:04:26.400,0:04:29.360 +means basically + +0:04:27.199,0:04:30.880 +checking a file checking all the content + +0:04:29.360,0:04:32.880 +of the file and extracting all the + +0:04:30.880,0:04:34.960 +information that we need from that file + +0:04:32.880,0:04:36.560 +and as you can imagine you all have + +0:04:34.960,0:04:38.240 +augmented files in your mind + +0:04:36.560,0:04:39.840 +well you know they can be fairly complex + +0:04:38.240,0:04:41.759 +you know you can have properties + +0:04:39.840,0:04:43.040 +you can have contextual information like + +0:04:41.759,0:04:45.199 +if you write a line + +0:04:43.040,0:04:46.560 +which starts at column zero which means + +0:04:45.199,0:04:48.000 +at the left + +0:04:46.560,0:04:49.680 +you know it doesn't have the same + +0:04:48.000,0:04:52.639 +meaning whether or not it is + +0:04:49.680,0:04:54.160 +before the beginning of a headline or if + +0:04:52.639,0:04:55.199 +it is after the beginning of a red line + +0:04:54.160,0:04:57.759 +you know it's going to be + +0:04:55.199,0:04:58.960 +relatively different hierarchically + +0:04:57.759,0:05:01.759 +speaking + +0:04:58.960,0:05:02.639 +and so the problem when it comes to the + +0:05:01.759,0:05:05.759 +question of + +0:05:02.639,0:05:08.560 +many files versus one big file or + +0:05:05.759,0:05:09.600 +few big files is that we always have to + +0:05:08.560,0:05:12.880 +keep in mind + +0:05:09.600,0:05:15.680 +what org elements want you to do + +0:05:12.880,0:05:17.440 +and the thing is there are plenty of + +0:05:15.680,0:05:18.400 +problems when it comes to passing file + +0:05:17.440,0:05:21.360 +the first one + +0:05:18.400,0:05:22.160 +being obviously that emacs is a single + +0:05:21.360,0:05:24.880 +thread + +0:05:22.160,0:05:26.400 +process or has some threading + +0:05:24.880,0:05:28.639 +capabilities we're not going to go into + +0:05:26.400,0:05:32.400 +the details right now that's not my goal + +0:05:28.639,0:05:35.919 +but it makes it incredibly hard to + +0:05:32.400,0:05:39.280 +parallelize uh passing processes as + +0:05:35.919,0:05:42.320 +we currently with the current technology + +0:05:39.280,0:05:44.080 +and so you'd have to imagine that if you + +0:05:42.320,0:05:46.479 +have a very large files if you go back + +0:05:44.080,0:05:49.199 +to the example of carl voice from before + +0:05:46.479,0:05:50.000 +100 000 lines that means that you have + +0:05:49.199,0:05:52.320 +to scan + +0:05:50.000,0:05:53.759 +through every single line basically + +0:05:52.320,0:05:56.080 +because sometimes let's just say that + +0:05:53.759,0:05:59.440 +you have a property drawer for instance + +0:05:56.080,0:06:03.520 +which tells you oh okay uh this tree + +0:05:59.440,0:06:05.120 +has the tag foo so the problem is there + +0:06:03.520,0:06:08.720 +are multiple ways for you + +0:06:05.120,0:06:11.840 +to define a tag okay so you can use the + +0:06:08.720,0:06:14.000 +usual way which is about wrapping in + +0:06:11.840,0:06:16.160 +columns the tag at the end of a heading + +0:06:14.000,0:06:17.360 +so for instance if i i'm not going to + +0:06:16.160,0:06:18.240 +switch to emac that's going to waste too + +0:06:17.360,0:06:21.039 +much time + +0:06:18.240,0:06:21.520 +but that's one way to say your time but + +0:06:21.039,0:06:23.520 +say + +0:06:21.520,0:06:25.360 +you have tag inheritance which means + +0:06:23.520,0:06:28.160 +that when you have a parent with a tag + +0:06:25.360,0:06:29.520 +you also want the child to inherit the + +0:06:28.160,0:06:32.400 +tag so if you have + +0:06:29.520,0:06:33.680 +first heading with the typhoo you have + +0:06:32.400,0:06:37.520 +the first subheading + +0:06:33.680,0:06:39.680 +and the tag foo is implied now imagine + +0:06:37.520,0:06:41.039 +having to do that with a file that is + +0:06:39.680,0:06:44.160 +completely nested + +0:06:41.039,0:06:47.280 +a file that has maybe 9 10 + +0:06:44.160,0:06:49.039 +11 levels of depth to it + +0:06:47.280,0:06:51.039 +it's mind-bogglingly complicated for the + +0:06:49.039,0:06:52.639 +software to do that knowing that i've + +0:06:51.039,0:06:55.919 +told you about tags + +0:06:52.639,0:06:58.639 +but any property can be inheritable + +0:06:55.919,0:07:00.240 +anything like priorities even though why + +0:06:58.639,0:07:03.759 +would you do this + +0:07:00.240,0:07:05.599 +you can have groups you can all this and + +0:07:03.759,0:07:07.199 +as someone who went through the trouble + +0:07:05.599,0:07:08.560 +of optimizing his old agenda so + +0:07:07.199,0:07:11.280 +basically if we go back to the + +0:07:08.560,0:07:12.160 +gifts gifs oh god we've already had this + +0:07:11.280,0:07:14.479 +discussion + +0:07:12.160,0:07:16.400 +between the git and magit and now i've + +0:07:14.479,0:07:18.080 +started jeff and gif and i only have one + +0:07:16.400,0:07:19.599 +more minute left to do so so let's just + +0:07:18.080,0:07:23.599 +say i'm going to say gif + +0:07:19.599,0:07:26.880 +just to spice people so if you go on + +0:07:23.599,0:07:29.120 +the way i organize my agenda what i did + +0:07:26.880,0:07:30.960 +in order to keep my agenda build time + +0:07:29.120,0:07:33.440 +under two seconds + +0:07:30.960,0:07:35.520 +is that i've rewritten a whole lot of + +0:07:33.440,0:07:36.560 +codes to be able to pass my organ gender + +0:07:35.520,0:07:40.080 +files + +0:07:36.560,0:07:41.360 +so the thing is i'm going to be talking + +0:07:40.080,0:07:43.440 +more about this later + +0:07:41.360,0:07:44.479 +i only have let's say one minutes to + +0:07:43.440,0:07:47.440 +conclude + +0:07:44.479,0:07:48.479 +so as you've gathered i'm not going to + +0:07:47.440,0:07:51.039 +be giving you the answer + +0:07:48.479,0:07:53.440 +right now i'm going to be talking about + +0:07:51.039,0:07:55.680 +orgrum a little later which is about + +0:07:53.440,0:07:57.759 +following the principle of having many + +0:07:55.680,0:08:01.120 +small files + +0:07:57.759,0:08:02.960 +but as someone who has been using + +0:08:01.120,0:08:04.879 +one large file to manage my life you + +0:08:02.960,0:08:08.319 +know i'm sitting on the fence + +0:08:04.879,0:08:10.560 +i do not know which one is the best + +0:08:08.319,0:08:12.240 +but i hope that my presentation has + +0:08:10.560,0:08:15.199 +given you a little id + +0:08:12.240,0:08:15.520 +of what goes on behind the principles + +0:08:15.199,0:08:16.560 +and + +0:08:15.520,0:08:18.560 +you also need to think about the + +0:08:16.560,0:08:19.120 +philosophy behind the organization of + +0:08:18.560,0:08:21.039 +your notes + +0:08:19.120,0:08:23.280 +but i hope to be approaching this topic + +0:08:21.039,0:08:25.360 +with you in about + +0:08:23.280,0:08:27.520 +two hours or so maybe one hour actually + +0:08:25.360,0:08:28.960 +so i'm actually finished i've decided to + +0:08:27.520,0:08:31.520 +leave you two minutes of questions + +0:08:28.960,0:08:32.880 +so uh if someone could feed me the + +0:08:31.520,0:08:34.399 +question that might be best + +0:08:32.880,0:08:36.240 +because i don't want oh actually i can + +0:08:34.399,0:08:39.919 +just open the year + +0:08:36.240,0:08:40.800 +i can just open it give me a second okay + +0:08:39.919,0:08:43.039 +ah + +0:08:40.800,0:08:43.839 +just loading up huh i might stop showing + +0:08:43.039,0:08:46.959 +my screen + +0:08:43.839,0:08:47.519 +that might make it easier so i mean if + +0:08:46.959,0:08:49.360 +you can make + +0:08:47.519,0:08:52.000 +myself big now on the screen that would + +0:08:49.360,0:08:55.839 +be splendid yeah sure + +0:08:52.000,0:08:58.720 +thank you so uh where are we + +0:08:55.839,0:09:00.160 +question 12. okay so what's better one + +0:08:58.720,0:09:02.160 +big file + +0:09:00.160,0:09:03.120 +i did is it did a job to tell me that i + +0:09:02.160,0:09:04.240 +haven't answered the question because + +0:09:03.120,0:09:06.320 +someone just + +0:09:04.240,0:09:08.080 +asked me the question well personally if + +0:09:06.320,0:09:08.560 +i were to give you a quick answer in + +0:09:08.080,0:09:11.600 +like + +0:09:08.560,0:09:13.920 +20 seconds personally i think it's a + +0:09:11.600,0:09:15.680 +question that is contextually based + +0:09:13.920,0:09:17.839 +do you want something that is efficient + +0:09:15.680,0:09:21.200 +as far as optimization is concerned + +0:09:17.839,0:09:23.440 +then you need to think about + +0:09:21.200,0:09:24.640 +this and personally for all the + +0:09:23.440,0:09:26.640 +organization that i do + +0:09:24.640,0:09:27.760 +all this stuff all the to-do's that i + +0:09:26.640,0:09:30.080 +handle + +0:09:27.760,0:09:31.519 +i like to do this in one simple big file + +0:09:30.080,0:09:33.760 +because you benefit from all the + +0:09:31.519,0:09:36.320 +refiling capabilities of log mode + +0:09:33.760,0:09:37.200 +so i would do that but for knowledge + +0:09:36.320,0:09:40.080 +management + +0:09:37.200,0:09:41.279 +for note-taking and all this well i'd + +0:09:40.080,0:09:42.959 +much rather follow the + +0:09:41.279,0:09:44.480 +orgrom way of doing things which is + +0:09:42.959,0:09:48.240 +about having many + +0:09:44.480,0:09:50.000 +small files okay i'm not getting any + +0:09:48.240,0:09:52.080 +more questions i'm not sure if there is + +0:09:50.000,0:09:53.040 +one on ise that could be fed to me + +0:09:52.080,0:09:56.399 +otherwise i'm + +0:09:53.040,0:09:57.040 +happy to to uh pass over to the next uh + +0:09:56.399,0:09:59.360 +speaker + +0:09:57.040,0:10:01.360 +and by the way just before i finish your + +0:09:59.360,0:10:04.399 +world is a lie it's not a three-piece + +0:10:01.360,0:10:06.520 +suit i'm wearing jeans below so i hope + +0:10:04.399,0:10:09.610 +that satisfies your curiosity + +0:10:06.520,0:10:09.610 +[Music] + +0:10:10.640,0:10:15.040 +okay there's one more question appearing + +0:10:12.640,0:10:17.680 +but otherwise one big file to have + +0:10:15.040,0:10:19.760 +everything so i'm putting you on the + +0:10:17.680,0:10:21.040 +spot i believe it was such a short talk + +0:10:19.760,0:10:23.600 +you know the problem is + +0:10:21.040,0:10:24.720 +i just wanted to give you a little + +0:10:23.600,0:10:26.959 +answer + +0:10:24.720,0:10:27.920 +a little you know path of thinking on + +0:10:26.959,0:10:29.839 +this topic + +0:10:27.920,0:10:31.600 +but obviously it's a topic i could be + +0:10:29.839,0:10:33.200 +spending 40 minutes on but + +0:10:31.600,0:10:35.120 +i'm going to be drained you're going to + +0:10:33.200,0:10:35.680 +be drained nobody's going to be happy if + +0:10:35.120,0:10:37.920 +i do this + +0:10:35.680,0:10:37.920 +so + +0:10:39.440,0:10:42.880 +and someone asked me if i switch between + +0:10:41.200,0:10:46.560 +british and french accents + +0:10:42.880,0:10:48.480 +so a little a little secret for you um + +0:10:46.560,0:10:49.760 +when i'm stressed i tend to relate to a + +0:10:48.480,0:10:53.760 +french accent + +0:10:49.760,0:10:56.160 +so you can measure the amount of stress + +0:10:53.760,0:10:58.880 +that i'm feeling during this talk + +0:10:56.160,0:11:00.560 +with the amount of h's that i drop and + +0:10:58.880,0:11:02.720 +the amount of uh + +0:11:00.560,0:11:04.399 +sheer fright that you can see sometimes + +0:11:02.720,0:11:07.200 +in my eyes when i'm thinking about what + +0:11:04.399,0:11:07.200 +to say next + +0:11:08.240,0:11:11.360 +all right sir so i mean do you believe + +0:11:10.880,0:11:14.240 +we can + +0:11:11.360,0:11:15.519 +leave it at that and uh i'll be you + +0:11:14.240,0:11:17.040 +people will see plenty more with me + +0:11:15.519,0:11:20.000 +later on anyway + +0:11:17.040,0:11:20.640 +right um so looking at the schedule i + +0:11:20.000,0:11:23.920 +think + +0:11:20.640,0:11:27.120 +your talk has until like 202 meaning + +0:11:23.920,0:11:28.000 +like five or six minutes from now oh + +0:11:27.120,0:11:30.000 +right + +0:11:28.000,0:11:31.680 +yeah so if you do like to take like one + +0:11:30.000,0:11:33.920 +or two questions to add two more + +0:11:31.680,0:11:37.040 +questions by all means + +0:11:33.920,0:11:38.320 +okay so uh someone has asked me what is + +0:11:37.040,0:11:40.640 +the emacs icon + +0:11:38.320,0:11:42.880 +icon sorry see another french accent + +0:11:40.640,0:11:44.880 +here uh in my status bar + +0:11:42.880,0:11:46.640 +uh oh sorry i'm not sharing anymore uh i + +0:11:44.880,0:11:49.200 +might just share again just so that + +0:11:46.640,0:11:53.120 +everyone can catch a glimpse of that + +0:11:49.200,0:11:54.880 +uh there we go allow + +0:11:53.120,0:11:56.240 +so it should be so if you could make me + +0:11:54.880,0:11:56.959 +small again i'm in i'm not sure if it's + +0:11:56.240,0:12:00.480 +going to do it + +0:11:56.959,0:12:01.839 +by itself but i do have a little icon + +0:12:00.480,0:12:04.480 +here in my status bar + +0:12:01.839,0:12:05.760 +which is basically a way to interact + +0:12:04.480,0:12:07.279 +with all protocol + +0:12:05.760,0:12:09.120 +uh i'm not going to look for it right + +0:12:07.279,0:12:10.800 +now but it's uh + +0:12:09.120,0:12:12.399 +it's a browser extension that is + +0:12:10.800,0:12:15.680 +developed by one of my friends + +0:12:12.399,0:12:16.160 +over at ranger whose name is v phone and + +0:12:15.680,0:12:18.240 +uh + +0:12:16.160,0:12:19.680 +it's very useful i'm someone who uses a + +0:12:18.240,0:12:22.320 +lot of uh + +0:12:19.680,0:12:23.040 +of uh all protocols and by the way i + +0:12:22.320,0:12:25.279 +used to teach + +0:12:23.040,0:12:27.279 +english okay to high schoolers and they + +0:12:25.279,0:12:29.600 +were supremely worried + +0:12:27.279,0:12:30.800 +when i show them my status line and they + +0:12:29.600,0:12:34.000 +so kill + +0:12:30.800,0:12:36.560 +and explore in my status line so as + +0:12:34.000,0:12:37.839 +fellow emacs users you know that + +0:12:36.560,0:12:40.880 +obviously kill + +0:12:37.839,0:12:44.320 +means to kill a selection of text and + +0:12:40.880,0:12:47.279 +keep it inside your clipboard + +0:12:44.320,0:12:48.320 +but for my students who you know they + +0:12:47.279,0:12:51.600 +were very worried + +0:12:48.320,0:12:53.600 +about what their professor was up to + +0:12:51.600,0:12:55.120 +doing his nights + +0:12:53.600,0:12:56.560 +so let's see if we've got more questions + +0:12:55.120,0:12:57.920 +so i'm showing you the questions on the + +0:12:56.560,0:13:00.560 +rainbow so let's see if + +0:12:57.920,0:13:01.920 +we've got more so people are posting a + +0:13:00.560,0:13:03.920 +lot of questions now + +0:13:01.920,0:13:06.399 +so how do you feel about archiving files + +0:13:03.920,0:13:09.360 +in old mode and how can that work in + +0:13:06.399,0:13:10.240 +so one of the thing when we think about + +0:13:09.360,0:13:13.920 +optimization + +0:13:10.240,0:13:16.240 +is yes archiving done trees + +0:13:13.920,0:13:17.920 +is a good idea because it means that if + +0:13:16.240,0:13:18.720 +we go back to the org element the way it + +0:13:17.920,0:13:20.399 +works + +0:13:18.720,0:13:22.079 +and we'll get into technical details + +0:13:20.399,0:13:24.079 +afterwards i'm giving a presentation + +0:13:22.079,0:13:26.880 +about all grown technical suspect + +0:13:24.079,0:13:28.399 +aspects sorry so i'll have a chance to + +0:13:26.880,0:13:31.360 +expand a little more on this + +0:13:28.399,0:13:32.160 +but basically all elements need to uh + +0:13:31.360,0:13:35.279 +every time + +0:13:32.160,0:13:38.320 +it sees a to do it has to consider it + +0:13:35.279,0:13:40.000 +even though it is a done to do why + +0:13:38.320,0:13:41.839 +because let's say for instance that in + +0:13:40.000,0:13:45.519 +your agenda you want to activate + +0:13:41.839,0:13:48.959 +log mode which is going to show the + +0:13:45.519,0:13:49.519 +tasks which are done now you could be + +0:13:48.959,0:13:51.440 +clever + +0:13:49.519,0:13:53.360 +and say oh okay the old agenda does not + +0:13:51.440,0:13:54.880 +need to show don items so it's not going + +0:13:53.360,0:13:56.959 +to look for them + +0:13:54.880,0:13:58.720 +but the problem is that all elements is + +0:13:56.959,0:13:59.519 +always called it always needs to pass + +0:13:58.720,0:14:01.839 +the buffer + +0:13:59.519,0:14:03.519 +you know uh nicodego as you who is the + +0:14:01.839,0:14:05.040 +french developer who's worked a whole + +0:14:03.519,0:14:07.440 +lot on all elements + +0:14:05.040,0:14:08.399 +has gone through a lot of trouble to + +0:14:07.440,0:14:11.600 +optimize all + +0:14:08.399,0:14:13.279 +elements but the problem is + +0:14:11.600,0:14:14.720 +there's just so much that we can do with + +0:14:13.279,0:14:18.560 +a concurrent process + +0:14:14.720,0:14:21.120 +and right now it leaves somewhat + +0:14:18.560,0:14:22.079 +uh you know things to be desired but + +0:14:21.120,0:14:24.800 +we're working on it + +0:14:22.079,0:14:25.839 +and one more time i feel like i spent + +0:14:24.800,0:14:28.000 +half of this talk + +0:14:25.839,0:14:29.360 +teasing my next talks but i'll be + +0:14:28.000,0:14:31.279 +talking more about this + +0:14:29.360,0:14:32.639 +in my future talks in about one to two + +0:14:31.279,0:14:34.959 +hours + +0:14:32.639,0:14:36.079 +so continuing with questions how big are + +0:14:34.959,0:14:37.760 +my org files + +0:14:36.079,0:14:39.839 +so in the background i'm just going to + +0:14:37.760,0:14:40.720 +check how many lines i have in my main + +0:14:39.839,0:14:42.959 +file + +0:14:40.720,0:14:44.079 +so in my own file so the one i told you + +0:14:42.959,0:14:47.279 +about where i keep all + +0:14:44.079,0:14:50.720 +my to do gtd stuff i have + +0:14:47.279,0:14:54.000 +38 000 lines which is + +0:14:50.720,0:14:57.040 +you know it's sizable definitely + +0:14:54.000,0:14:58.480 +but i do archive a lot of stuff + +0:14:57.040,0:15:00.880 +so that might be a slight difference + +0:14:58.480,0:15:02.079 +between uh my myself and carl voight + +0:15:00.880,0:15:04.880 +even though i don't remember if they + +0:15:02.079,0:15:06.639 +actually archive stuff + +0:15:04.880,0:15:08.480 +so does it not consume more resources + +0:15:06.639,0:15:10.839 +and time to load multiple files + +0:15:08.480,0:15:12.560 +files than a large file or the same + +0:15:10.839,0:15:15.839 +content now + +0:15:12.560,0:15:19.279 +theoretically yes having many files + +0:15:15.839,0:15:22.240 +open concurrently is slightly slower + +0:15:19.279,0:15:24.160 +than having one main file opened + +0:15:22.240,0:15:25.279 +now the problem is for those of you who + +0:15:24.160,0:15:27.199 +have large files + +0:15:25.279,0:15:29.360 +you may have noticed that when you are + +0:15:27.199,0:15:32.560 +scrolling in a very large file + +0:15:29.360,0:15:34.480 +it starts taking quite a bit of time why + +0:15:32.560,0:15:35.920 +it's because you know in old mode you + +0:15:34.480,0:15:38.959 +have a lot of content + +0:15:35.920,0:15:40.959 +that is hidden so when you have + +0:15:38.959,0:15:43.040 +the view mode which hides as much stuff + +0:15:40.959,0:15:43.600 +as possible means meaning that you only + +0:15:43.040,0:15:45.360 +see + +0:15:43.600,0:15:46.880 +the top heading and i'm checking the + +0:15:45.360,0:15:49.360 +time i mean don't worry i'm i'm finished + +0:15:46.880,0:15:49.360 +on this one + +0:15:50.240,0:15:53.360 +when you're hiding a whole lot of stuff + +0:15:52.160,0:15:54.720 +you know orgmo + +0:15:53.360,0:15:56.959 +needs to keep track or i should say + +0:15:54.720,0:15:58.160 +emacs needs to keep track of which areas + +0:15:56.959,0:16:00.560 +of text to show + +0:15:58.160,0:16:02.320 +and which areas of text to hide and the + +0:16:00.560,0:16:04.480 +problem is that when you're hiding stuff + +0:16:02.320,0:16:06.320 +let's say you're moving from line the + +0:16:04.480,0:16:08.639 +first heading to the second heading + +0:16:06.320,0:16:09.839 +but you've got like 10 000 lines between + +0:16:08.639,0:16:11.519 +those two headings + +0:16:09.839,0:16:13.680 +well he max needs to compute the + +0:16:11.519,0:16:15.680 +difference between the two passages + +0:16:13.680,0:16:17.040 +and that takes quite a lot of time and + +0:16:15.680,0:16:18.560 +in that that's my + +0:16:17.040,0:16:20.560 +why you might realize that it's a little + +0:16:18.560,0:16:21.199 +choppy when you start scrolling in large + +0:16:20.560,0:16:22.560 +files + +0:16:21.199,0:16:24.480 +anyway i could be answering questions + +0:16:22.560,0:16:25.120 +about org mode for literally two hours + +0:16:24.480,0:16:26.720 +straight + +0:16:25.120,0:16:28.639 +so i'm gonna end it over to the next + +0:16:26.720,0:16:31.759 +speakers and i'll be seeing + +0:16:28.639,0:16:33.440 +seeing you guys a little later thank you + +0:16:31.759,0:16:36.959 +very much leo + +0:16:33.440,0:16:39.839 +oh thank you yes bye + +0:16:36.959,0:16:39.839 +bye + diff --git

+0:00:00.320,0:00:05.920 +um so hi i'm joe corneli + +0:00:03.280,0:00:06.879 +uh this is work i did with ray puzio and + +0:00:05.920,0:00:10.559 +cameron smith + +0:00:06.879,0:00:11.599 +um and they're the main protagonists in + +0:00:10.559,0:00:14.960 +this story they + +0:00:11.599,0:00:17.840 +are uh researchers who've been working + +0:00:14.960,0:00:20.160 +on theoretical biology um so in a + +0:00:17.840,0:00:23.760 +typical project they may use manxima + +0:00:20.160,0:00:24.800 +and julia their work for biology physics + +0:00:23.760,0:00:27.199 +and computer science + +0:00:24.800,0:00:29.439 +computer science and the latest work in + +0:00:27.199,0:00:30.800 +progress is on branching processes for + +0:00:29.439,0:00:34.719 +cancer modeling so + +0:00:30.800,0:00:37.360 +how can um emacs possibly help + +0:00:34.719,0:00:38.399 +let's let's have a look uh moving code + +0:00:37.360,0:00:39.680 +and data between these different + +0:00:38.399,0:00:42.000 +programs by hand is + +0:00:39.680,0:00:43.200 +annoying on separate workflows for + +0:00:42.000,0:00:44.399 +writing up notes and preparing + +0:00:43.200,0:00:46.000 +publications + +0:00:44.399,0:00:48.640 +is perhaps even more annoying all of + +0:00:46.000,0:00:52.000 +it's time consuming and error-prone + +0:00:48.640,0:00:53.760 +um so what about maybe using jupiter + +0:00:52.000,0:00:55.199 +uh we found something called script of + +0:00:53.760,0:00:58.399 +scripts and it solves some of those + +0:00:55.199,0:01:01.120 +problems because you can use + +0:00:58.399,0:01:02.640 +maximum and julia together but we were + +0:01:01.120,0:01:05.199 +quite happy to explore emacs based + +0:01:02.640,0:01:05.840 +solutions being emax enthusiasts and we + +0:01:05.199,0:01:07.760 +even + +0:01:05.840,0:01:09.200 +got cameron to be enthusiastic about + +0:01:07.760,0:01:11.600 +doing emacs so that + +0:01:09.200,0:01:12.400 +went nice so just here's a little + +0:01:11.600,0:01:15.360 +feature grid + +0:01:12.400,0:01:16.400 +of emacs org versus just sort of your + +0:01:15.360,0:01:19.040 +generic + +0:01:16.400,0:01:20.960 +um tools that are in a different more + +0:01:19.040,0:01:21.520 +general ecosystem so as you can see it's + +0:01:20.960,0:01:23.360 +quite + +0:01:21.520,0:01:25.520 +feature complete you've got your maximo + +0:01:23.360,0:01:27.119 +mode julia mode you can use both of them + +0:01:25.520,0:01:28.720 +inside of org mode + +0:01:27.119,0:01:30.240 +you can present things with word tree + +0:01:28.720,0:01:33.280 +slide you can set up a + +0:01:30.240,0:01:33.680 +wiki inside of orgrome this is one i + +0:01:33.280,0:01:35.759 +found + +0:01:33.680,0:01:37.759 +rather recently you can even use + +0:01:35.759,0:01:38.799 +compatibly with orgrome something called + +0:01:37.759,0:01:41.520 +log seek + +0:01:38.799,0:01:42.159 +which is in the browser um so that's + +0:01:41.520,0:01:44.320 +nice + +0:01:42.159,0:01:45.840 +um you can do real-time collaborative + +0:01:44.320,0:01:47.840 +editing um + +0:01:45.840,0:01:49.280 +either in a kind of pairing style or in + +0:01:47.840,0:01:51.520 +a more etherpad style + +0:01:49.280,0:01:54.159 +obviously you can manage your references + +0:01:51.520,0:01:55.759 +you can typeset whatever you want um you + +0:01:54.159,0:01:57.439 +can publish work in progress on a blog + +0:01:55.759,0:01:58.159 +and the fern is another one of these + +0:01:57.439,0:02:00.560 +external + +0:01:58.159,0:02:01.360 +org mode tools it's not actually any mac + +0:02:00.560,0:02:03.680 +but works with + +0:02:01.360,0:02:04.399 +org mode stuff and you know so we're + +0:02:03.680,0:02:06.640 +good to go + +0:02:04.399,0:02:08.000 +uh with all of that so what does that + +0:02:06.640,0:02:09.679 +look like well here's + +0:02:08.000,0:02:11.599 +a little example from before they were + +0:02:09.679,0:02:12.800 +doing um + +0:02:11.599,0:02:14.560 +before we started really thinking + +0:02:12.800,0:02:15.599 +seriously about this stuff so this is + +0:02:14.560,0:02:17.440 +just maxima + +0:02:15.599,0:02:19.280 +well maximo doesn't have a long running + +0:02:17.440,0:02:20.160 +process by default if you've ever used + +0:02:19.280,0:02:22.480 +python + +0:02:20.160,0:02:23.920 +uh you have something called sessions uh + +0:02:22.480,0:02:24.959 +they don't have that for maxim at least + +0:02:23.920,0:02:27.599 +not by default + +0:02:24.959,0:02:29.360 +um so how what was the workaround + +0:02:27.599,0:02:32.480 +there's this thing called uh + +0:02:29.360,0:02:34.879 +solve for you here and um + +0:02:32.480,0:02:36.319 +that shows up down below again in these + +0:02:34.879,0:02:37.360 +angle brackets which you've seen maybe + +0:02:36.319,0:02:40.480 +in someone else's talk + +0:02:37.360,0:02:41.920 +uh which means go to the previous uh + +0:02:40.480,0:02:43.920 +thing that was named soul for you + +0:02:41.920,0:02:45.280 +and do that all over again so they do + +0:02:43.920,0:02:47.440 +that over again + +0:02:45.280,0:02:49.519 +and here's the little maxima code for + +0:02:47.440,0:02:50.560 +defining you saw so you've now defined + +0:02:49.519,0:02:51.920 +you saw + +0:02:50.560,0:02:54.000 +and then you can use it in the next + +0:02:51.920,0:02:56.560 +expression you get out a nice juicy + +0:02:54.000,0:02:57.200 +zero at the end but it's a little bit a + +0:02:56.560,0:02:58.959 +little bit + +0:02:57.200,0:03:00.640 +like cartridge in a pear tree to have to + +0:02:58.959,0:03:02.560 +redefine everything every time + +0:03:00.640,0:03:04.159 +so this is clearly at the level of work + +0:03:02.560,0:03:06.879 +around um maybe just + +0:03:04.159,0:03:07.920 +one more time going looking through that + +0:03:06.879,0:03:11.599 +um + +0:03:07.920,0:03:13.760 +that stuff um + +0:03:11.599,0:03:15.280 +sorry so uh looking through that stuff + +0:03:13.760,0:03:17.200 +this is we're going to need something + +0:03:15.280,0:03:19.599 +like that probably for stitching + +0:03:17.200,0:03:20.319 +maxima and julie julia together so it's + +0:03:19.599,0:03:21.680 +good to + +0:03:20.319,0:03:23.920 +look a little bit about how that might + +0:03:21.680,0:03:25.680 +work so first of all you can cache + +0:03:23.920,0:03:26.480 +results so if you wanted to save the + +0:03:25.680,0:03:28.480 +date + +0:03:26.480,0:03:29.920 +out of block one at a certain time and + +0:03:28.480,0:03:32.239 +then use + +0:03:29.920,0:03:33.280 +use it again later so at the time when i + +0:03:32.239,0:03:34.640 +ran this code + +0:03:33.280,0:03:36.720 +you can see i've got two slightly + +0:03:34.640,0:03:38.560 +different time stamps down below one's + +0:03:36.720,0:03:40.319 +the cached result and the other was the + +0:03:38.560,0:03:42.640 +result of reevaluating + +0:03:40.319,0:03:43.760 +the block so you can move things around + +0:03:42.640,0:03:46.000 +um and that's + +0:03:43.760,0:03:47.280 +that's going to be useful but you know + +0:03:46.000,0:03:48.080 +that's not really the main problem the + +0:03:47.280,0:03:50.799 +main problem is + +0:03:48.080,0:03:51.440 +making maxima long running so kind of + +0:03:50.799,0:03:53.920 +the + +0:03:51.440,0:03:56.400 +core of this talk is a new observant + +0:03:53.920,0:03:59.280 +facility which is a general purpose + +0:03:56.400,0:04:00.560 +way to do that kind of thing which + +0:03:59.280,0:04:04.239 +involves a very simple + +0:04:00.560,0:04:05.360 +change to obcor uh so we'll give a quick + +0:04:04.239,0:04:08.480 +overview of that and show + +0:04:05.360,0:04:11.760 +an example um so here's the example + +0:04:08.480,0:04:13.040 +um a very simple sort of silly example + +0:04:11.760,0:04:14.640 +uh what does it mean to have a long + +0:04:13.040,0:04:15.920 +running process here i've set this + +0:04:14.640,0:04:18.560 +display2d + +0:04:15.920,0:04:19.440 +to be false um which just means that + +0:04:18.560,0:04:22.320 +things are going to come + +0:04:19.440,0:04:23.040 +come across in 1d and then i ask it to + +0:04:22.320,0:04:25.199 +expand + +0:04:23.040,0:04:27.280 +uh something and i get latex by default + +0:04:25.199,0:04:28.639 +so so that's what it means is i've sent + +0:04:27.280,0:04:30.240 +something in and it's going to come + +0:04:28.639,0:04:32.080 +across in one view which is great + +0:04:30.240,0:04:34.560 +um maybe you'll also notice that there's + +0:04:32.080,0:04:36.720 +no semicolon if you're a maxima fan + +0:04:34.560,0:04:38.400 +um and things are coming across as tech + +0:04:36.720,0:04:40.320 +so those were some little bonus features + +0:04:38.400,0:04:41.040 +and i'll show you how that works later + +0:04:40.320,0:04:45.440 +so + +0:04:41.040,0:04:48.880 +um the change to obcor is as follows uh + +0:04:45.440,0:04:51.520 +um we uh actually this should say uh + +0:04:48.880,0:04:52.479 +instead of stream here it should say um + +0:04:51.520,0:04:54.800 +servant + +0:04:52.479,0:04:56.160 +sorry uh we tried an experimental + +0:04:54.800,0:04:58.160 +version what's called stream so now it's + +0:04:56.160,0:05:01.520 +called servant but all it does is it + +0:04:58.160,0:05:02.639 +overrides uh or babel execute laying for + +0:05:01.520,0:05:05.919 +arbitrary laying + +0:05:02.639,0:05:07.840 +if you have um a servant + +0:05:05.919,0:05:09.759 +in your in your params so that's the + +0:05:07.840,0:05:11.919 +change that hasn't been + +0:05:09.759,0:05:13.759 +pushed out or sent as a patch to anybody + +0:05:11.919,0:05:16.960 +but it's a pretty minor change + +0:05:13.759,0:05:19.080 +um here's an overview without the code + +0:05:16.960,0:05:20.720 +of just a high level overview of + +0:05:19.080,0:05:22.160 +observant.el so + +0:05:20.720,0:05:24.479 +it stores information about these + +0:05:22.160,0:05:26.080 +processes in a hash table + +0:05:24.479,0:05:27.600 +it can do pre-processing and + +0:05:26.080,0:05:29.759 +post-processing + +0:05:27.600,0:05:30.720 +um it does all these things it stores + +0:05:29.759,0:05:32.479 +the output + +0:05:30.720,0:05:34.080 +i mentioned here that in principle we + +0:05:32.479,0:05:35.280 +could store lots of output and have a + +0:05:34.080,0:05:36.560 +kind of browsable + +0:05:35.280,0:05:38.880 +history although we don't do that + +0:05:36.560,0:05:40.639 +presently um but that's what observant + +0:05:38.880,0:05:41.440 +does is it does what you might expect + +0:05:40.639,0:05:45.440 +and here's the + +0:05:41.440,0:05:48.160 +here's the maxima kind of um + +0:05:45.440,0:05:49.600 +on-ramp uh to get maxima brought in so + +0:05:48.160,0:05:51.360 +you have to obviously have a maximum + +0:05:49.600,0:05:54.960 +process you can call + +0:05:51.360,0:05:57.840 +um put hash uh this is the preprocessing + +0:05:54.960,0:05:58.960 +thing i mentioned adding in some tech um + +0:05:57.840,0:06:01.520 +and adding in + +0:05:58.960,0:06:03.120 +uh or deleting rather a substring and + +0:06:01.520,0:06:03.759 +here here is why you delete the + +0:06:03.120,0:06:06.960 +substring + +0:06:03.759,0:06:08.240 +is because um maxima thinks it's a good + +0:06:06.960,0:06:10.080 +idea to tell you false + +0:06:08.240,0:06:11.759 +once you once you run check on things + +0:06:10.080,0:06:13.680 +you've got to delete that back out to + +0:06:11.759,0:06:16.960 +get something kind of coherent out of it + +0:06:13.680,0:06:19.280 +but so this is how to set up maximal um + +0:06:16.960,0:06:20.000 +that's enough really of the demo is not + +0:06:19.280,0:06:21.919 +really a demos for + +0:06:20.000,0:06:23.600 +show and tell but uh this is an + +0:06:21.919,0:06:25.440 +experience report i wanted to talk about + +0:06:23.600,0:06:28.080 +the experience of doing this + +0:06:25.440,0:06:30.160 +so some some negatives like we tried to + +0:06:28.080,0:06:33.199 +get emacs jupiter working + +0:06:30.160,0:06:36.000 +prior to prior to working on the um + +0:06:33.199,0:06:37.919 +observant and we couldn't get it doing + +0:06:36.000,0:06:40.160 +everything we wanted despite a bit of + +0:06:37.919,0:06:41.840 +heavy lifting and debugging and stuff so + +0:06:40.160,0:06:42.880 +that's not not finished that was a bit + +0:06:41.840,0:06:45.360 +difficult + +0:06:42.880,0:06:47.759 +um on the other hand working on + +0:06:45.360,0:06:48.479 +observing was fun and pretty lightweight + +0:06:47.759,0:06:50.400 +and easy + +0:06:48.479,0:06:52.400 +um we got some experience co-editing + +0:06:50.400,0:06:54.479 +things with these real-time tools + +0:06:52.400,0:06:55.919 +obviously the stack is somewhat work in + +0:06:54.479,0:06:58.000 +progress um + +0:06:55.919,0:07:00.800 +so i just wanted to give a shout out to + +0:06:58.000,0:07:03.919 +crdt which was really fun + +0:07:00.800,0:07:07.039 +and champion was making bug fiction + +0:07:03.919,0:07:08.960 +bug fixes for that as we go similarly + +0:07:07.039,0:07:10.160 +for fern and log seek the maintainers + +0:07:08.960,0:07:12.960 +were really responsive + +0:07:10.160,0:07:14.560 +um and so that was nice we did try to + +0:07:12.960,0:07:15.840 +get emacs running in the browser + +0:07:14.560,0:07:16.880 +thinking it would be really nice for + +0:07:15.840,0:07:19.520 +people who + +0:07:16.880,0:07:21.120 +um didn't want to install it to get a + +0:07:19.520,0:07:23.120 +chance to just try it + +0:07:21.120,0:07:24.479 +uh but actually browsers capture things + +0:07:23.120,0:07:27.120 +like uh control n + +0:07:24.479,0:07:28.479 +and so that's that was a bit annoying + +0:07:27.120,0:07:29.759 +but we did get lots of great feedback + +0:07:28.479,0:07:31.599 +and interaction with people including + +0:07:29.759,0:07:33.759 +around this conference so thank you + +0:07:31.599,0:07:35.599 +to those who we've had discussions with + +0:07:33.759,0:07:37.680 +um + +0:07:35.599,0:07:38.639 +so future work okay so maybe you + +0:07:37.680,0:07:41.039 +remember i didn't + +0:07:38.639,0:07:42.400 +give a talk a few years back on arcana + +0:07:41.039,0:07:44.479 +so what what + +0:07:42.400,0:07:45.919 +might this have to do with org mode and + +0:07:44.479,0:07:47.039 +that's always the question one asks + +0:07:45.919,0:07:48.720 +about arcata + +0:07:47.039,0:07:50.319 +well so arcana one of the things it does + +0:07:48.720,0:07:51.680 +is transclusions and so that could be + +0:07:50.319,0:07:54.000 +actually very helpful + +0:07:51.680,0:07:55.520 +in connection with this combined notes + +0:07:54.000,0:07:56.479 +and write-up workflow so you might have + +0:07:55.520,0:07:58.400 +a + +0:07:56.479,0:08:00.800 +forward mode uh and some of these + +0:07:58.400,0:08:03.199 +results we got back as raw results + +0:08:00.800,0:08:03.919 +could go right into your write up in a + +0:08:03.199,0:08:07.520 +kind of + +0:08:03.919,0:08:09.039 +convenient way at a level above um + +0:08:07.520,0:08:11.280 +transparently a level above the notebook + +0:08:09.039,0:08:13.440 +so you'd have the notebook alongside the + +0:08:11.280,0:08:15.599 +write-up in that case + +0:08:13.440,0:08:16.800 +which is a sort of variation on the + +0:08:15.599,0:08:19.120 +literate programming + +0:08:16.800,0:08:20.000 +workflow this is speculative who knows + +0:08:19.120,0:08:22.080 +the other thought is + +0:08:20.000,0:08:23.520 +it just relates to the idea of network + +0:08:22.080,0:08:24.800 +programming so we can imagine these + +0:08:23.520,0:08:26.639 +networks of + +0:08:24.800,0:08:28.800 +computational nodes maybe sitting inside + +0:08:26.639,0:08:31.199 +of orgrome calling each other + +0:08:28.800,0:08:32.560 +um and you would want to maintain some + +0:08:31.199,0:08:34.959 +kind of model of that + +0:08:32.560,0:08:36.640 +process and a sort of general question + +0:08:34.959,0:08:38.320 +is how do we have a remote control for + +0:08:36.640,0:08:40.240 +long-running processes you could do that + +0:08:38.320,0:08:42.479 +in lisp or closure but + +0:08:40.240,0:08:44.080 +maybe we could have something a little + +0:08:42.479,0:08:45.839 +bit like that here + +0:08:44.080,0:08:48.080 +um so conclusions what have we actually + +0:08:45.839,0:08:50.080 +addressed well uh we addressed uh + +0:08:48.080,0:08:51.600 +accessing any long-running process with + +0:08:50.080,0:08:52.959 +a simple or mode interface + +0:08:51.600,0:08:54.880 +obviously we're not the only people to + +0:08:52.959,0:08:56.880 +think about notebooks but we think that + +0:08:54.880,0:08:58.880 +emacs has some advantages + +0:08:56.880,0:09:01.120 +related to reproducible research and + +0:08:58.880,0:09:01.680 +interdisciplinary collaboration so let's + +0:09:01.120,0:09:03.120 +just + +0:09:01.680,0:09:04.880 +say that we think something is + +0:09:03.120,0:09:07.200 +reproducible if it's actually teachable + +0:09:04.880,0:09:09.279 +to someone new and they can do it + +0:09:07.200,0:09:11.680 +org mode seems very useful for that many + +0:09:09.279,0:09:14.399 +of the other talks have touched on this + +0:09:11.680,0:09:16.000 +interdisciplinary collaboration is great + +0:09:14.399,0:09:17.839 +this was an interdisciplinary + +0:09:16.000,0:09:19.680 +collaboration on some level but + +0:09:17.839,0:09:21.600 +what about you know future work for + +0:09:19.680,0:09:22.320 +bringing in scenario planners simulation + +0:09:21.600,0:09:24.480 +scientists + +0:09:22.320,0:09:25.519 +and local farmers and building something + +0:09:24.480,0:09:27.200 +that they can all + +0:09:25.519,0:09:29.200 +use that's more than the sum of the + +0:09:27.200,0:09:30.720 +parts so a little + +0:09:29.200,0:09:32.160 +future work for everybody else here so + +0:09:30.720,0:09:33.120 +we think science should be widely + +0:09:32.160,0:09:34.560 +teachable + +0:09:33.120,0:09:36.720 +shareable semi-automated + +0:09:34.560,0:09:40.399 +transdisciplinary and real time + +0:09:36.720,0:09:43.279 +like emacs conf so you can get in touch + +0:09:40.399,0:09:44.560 +uh via these methods and the code which + +0:09:43.279,0:09:45.200 +is very much early stage work in + +0:09:44.560,0:09:46.640 +progress + +0:09:45.200,0:09:48.800 +as this was meant to be an experience + +0:09:46.640,0:09:49.920 +report not a it's all done here it is + +0:09:48.800,0:09:51.680 +polished report + +0:09:49.920,0:09:53.360 +um it's also online if you'd like to + +0:09:51.680,0:09:54.560 +have a look so that's the end of the + +0:09:53.360,0:09:55.279 +talk and i don't know if there's time + +0:09:54.560,0:09:57.440 +for questions + +0:09:55.279,0:10:00.240 +or not but um i'm at your disposal now + +0:09:57.440,0:10:04.079 +thank you you are now unmuted + +0:10:00.240,0:10:07.120 +um many thanks for the tough job + +0:10:04.079,0:10:08.880 +uh let's see we have about i think four + +0:10:07.120,0:10:10.880 +minutes four questions + +0:10:08.880,0:10:12.320 +um and we have a couple of questions on + +0:10:10.880,0:10:14.240 +the pad would you like to read them + +0:10:12.320,0:10:16.560 +yourself or should i read them to you + +0:10:14.240,0:10:18.079 +uh just for sake of easy management why + +0:10:16.560,0:10:21.279 +don't you read them out if that's okay + +0:10:18.079,0:10:22.240 +yeah sure uh so they ask have you looked + +0:10:21.279,0:10:25.440 +into trying + +0:10:22.240,0:10:33.760 +sage math i've long uh long wanted + +0:10:25.440,0:10:36.959 +nothing org files + +0:10:33.760,0:10:39.279 +right and i and i wrote the answer that + +0:10:36.959,0:10:42.079 +we should be possible because one can + +0:10:39.279,0:10:42.079 +call it from a command + +0:10:44.839,0:10:48.640 +okay + +0:10:46.399,0:10:50.079 +and i see there's another sagemath + +0:10:48.640,0:10:52.100 +question that you seem to have answered + +0:10:50.079,0:10:54.880 +as well so i guess i won't repeat that + +0:10:52.100,0:10:56.959 +[Music] + +0:10:54.880,0:11:00.640 +there's let's not forget about embedded + +0:10:56.959,0:11:03.680 +calc in emacs + +0:11:00.640,0:11:05.040 +so so the first demos actually were with + +0:11:03.680,0:11:06.640 +calc so that's that's + +0:11:05.040,0:11:07.839 +useful uh although i think it was a + +0:11:06.640,0:11:08.240 +different kind of a different command + +0:11:07.839,0:11:11.839 +line + +0:11:08.240,0:11:13.839 +well that was the next calc yeah + +0:11:11.839,0:11:15.680 +so sure there is there is calc so that + +0:11:13.839,0:11:19.120 +would be calculus and + +0:11:15.680,0:11:21.839 +calc is already in org mode yeah + +0:11:19.120,0:11:21.839 +yeah yeah + +0:11:25.680,0:11:29.839 +um still looking for questions + +0:11:39.760,0:11:44.320 +okay i think that's about it i don't see + +0:11:41.760,0:11:47.440 +any questions on the ether pad + +0:11:44.320,0:11:50.480 +and let's see + +0:11:47.440,0:11:50.480 +anything on irc + +0:11:53.040,0:11:56.720 +um nothing but phrases and everyone + +0:11:55.760,0:11:59.120 +thanking you + +0:11:56.720,0:12:00.240 +thank you all right you're welcome + +0:11:59.120,0:12:02.880 +thanks a lot uh + +0:12:00.240,0:12:06.800 +we'll see you guys around then cheers + +0:12:02.880,0:12:06.800 +and see you around + diff --git

+welcome to readme driven design in emacs + +0:00:06.560,0:00:10.800 +by adam aard + +0:00:08.400,0:00:12.559 +if you're a programmer you're accustomed + +0:00:10.800,0:00:13.759 +to putting a readme file at the root of + +0:00:12.559,0:00:16.400 +your project + +0:00:13.759,0:00:17.600 +and it's usually a markdown file but if + +0:00:16.400,0:00:20.720 +you use an org + +0:00:17.600,0:00:22.560 +more an org mode file instead you can + +0:00:20.720,0:00:24.400 +take advantage of the great features + +0:00:22.560,0:00:25.920 +that org mode provides including + +0:00:24.400,0:00:28.000 +literate programming + +0:00:25.920,0:00:31.840 +which lets you generate your source code + +0:00:28.000,0:00:34.719 +and markdown documentation dynamically + +0:00:31.840,0:00:37.120 +i want to walk you through a little bit + +0:00:34.719,0:00:39.440 +of what this looks like + +0:00:37.120,0:00:41.280 +when you start a project especially if + +0:00:39.440,0:00:43.320 +if you use something like github you + +0:00:41.280,0:00:47.039 +begin with an automatically generated + +0:00:43.320,0:00:50.239 +readme.md file so just delete that + +0:00:47.039,0:00:51.920 +and instead create a readme.org file + +0:00:50.239,0:00:54.800 +starting with an empty org file like you + +0:00:51.920,0:00:56.559 +see here you can begin + +0:00:54.800,0:00:59.440 +by recording important information about + +0:00:56.559,0:01:01.920 +your project goals you can add diagrams + +0:00:59.440,0:01:03.520 +code snippets to-do lists time tracking + +0:01:01.920,0:01:05.360 +and much more + +0:01:03.520,0:01:07.760 +i'm going to drop in some documentation + +0:01:05.360,0:01:10.840 +that i r that i've written about + +0:01:07.760,0:01:12.240 +about my project here so you can kind of + +0:01:10.840,0:01:15.280 +see + +0:01:12.240,0:01:17.119 +what this would look like + +0:01:15.280,0:01:20.320 +so as you can see i have a title and a + +0:01:17.119,0:01:23.840 +description and then a sub section + +0:01:20.320,0:01:25.520 +as well as some code snippets + +0:01:23.840,0:01:28.240 +and you can see that orgmo does a great + +0:01:25.520,0:01:31.280 +job of formatting lists and + +0:01:28.240,0:01:33.920 +code sections diagrams and so forth + +0:01:31.280,0:01:35.040 +it's good or it's as good or better than + +0:01:33.920,0:01:37.520 +markdown + +0:01:35.040,0:01:38.880 +but when you use it in the emacs you can + +0:01:37.520,0:01:40.479 +do a lot more + +0:01:38.880,0:01:43.360 +for example you can dynamically create + +0:01:40.479,0:01:45.200 +diagrams using graphviz + +0:01:43.360,0:01:46.560 +from a text description so if you go to + +0:01:45.200,0:01:49.439 +this source block here + +0:01:46.560,0:01:51.439 +and hit control c control c you'll see + +0:01:49.439,0:01:55.439 +that we generate a + +0:01:51.439,0:01:59.200 +diagram dynamically you can run + +0:01:55.439,0:02:00.799 +so you can run these code snippets in + +0:01:59.200,0:02:03.040 +place and get the results + +0:02:00.799,0:02:06.640 +to show up inside of your your file + +0:02:03.040,0:02:06.640 +which is a really powerful paradigm + +0:02:08.000,0:02:11.520 +but most important most importantly for + +0:02:10.640,0:02:14.800 +the + +0:02:11.520,0:02:17.200 +purposes my purpose is here + +0:02:14.800,0:02:19.520 +orgmo provides you the ability to do + +0:02:17.200,0:02:21.440 +literate programming + +0:02:19.520,0:02:23.200 +so take a quick look at this diagram + +0:02:21.440,0:02:25.360 +that i generated here + +0:02:23.200,0:02:27.520 +and gives you a quick overview of what i + +0:02:25.360,0:02:31.200 +mean by literate programming + +0:02:27.520,0:02:33.920 +and how i'm using it you can see + +0:02:31.200,0:02:34.720 +that we start with a readme.org file on + +0:02:33.920,0:02:36.879 +top + +0:02:34.720,0:02:37.920 +at this point we can do one of two + +0:02:36.879,0:02:41.280 +things + +0:02:37.920,0:02:42.720 +tangle or weave tangle is used to + +0:02:41.280,0:02:46.319 +describe the process of + +0:02:42.720,0:02:47.599 +generating source code while weave + +0:02:46.319,0:02:49.840 +is the process of generating + +0:02:47.599,0:02:51.920 +documentation these are terms that + +0:02:49.840,0:02:53.840 +donald knuth used + +0:02:51.920,0:02:55.519 +and he's the one that came up with the + +0:02:53.840,0:02:59.920 +idea of literate programming + +0:02:55.519,0:03:01.519 +in the early 1980s + +0:02:59.920,0:03:04.480 +but this is really all that there is to + +0:03:01.519,0:03:06.400 +it you just + +0:03:04.480,0:03:07.840 +who are simply using literate illiterate + +0:03:06.400,0:03:10.319 +source file + +0:03:07.840,0:03:11.680 +in this case the readme.org to generate + +0:03:10.319,0:03:15.680 +the rest of the project + +0:03:11.680,0:03:15.680 +the rest of the project files basically + +0:03:17.120,0:03:22.640 +so let's dig in to the details of how + +0:03:20.959,0:03:24.560 +this works + +0:03:22.640,0:03:26.159 +and i hope you hopefully you'll see how + +0:03:24.560,0:03:28.959 +cool this is + +0:03:26.159,0:03:31.120 +so returning to the file here let's + +0:03:28.959,0:03:32.080 +assume we have enough documentation now + +0:03:31.120,0:03:34.159 +that we want to get started + +0:03:32.080,0:03:35.519 +coding so maybe we'll just start with + +0:03:34.159,0:03:38.159 +like a hello world + +0:03:35.519,0:03:41.519 +app just so we can make sure that our + +0:03:38.159,0:03:47.120 +environment is set up correctly + +0:03:41.519,0:03:49.519 +so let's get started with a code block + +0:03:47.120,0:03:50.319 +so i created a little snippet to help me + +0:03:49.519,0:03:52.239 +add + +0:03:50.319,0:03:53.599 +a source block for literate programming + +0:03:52.239,0:03:56.959 +quickly + +0:03:53.599,0:03:58.799 +and there's not much to it + +0:03:56.959,0:04:01.599 +but there is some important annotations + +0:03:58.799,0:04:04.080 +here so there's + +0:04:01.599,0:04:05.200 +excuse me there's a there's a property + +0:04:04.080,0:04:09.360 +called tangle + +0:04:05.200,0:04:13.280 +and that takes a value of a file name + +0:04:09.360,0:04:16.560 +and then there's also a no web property + +0:04:13.280,0:04:16.560 +called no export + +0:04:18.880,0:04:22.000 +and basically + +0:04:23.759,0:04:28.639 +basically the no export will explain + +0:04:26.800,0:04:32.080 +that a little bit + +0:04:28.639,0:04:33.919 +more later um it has has to do with how + +0:04:32.080,0:04:37.600 +the tangling + +0:04:33.919,0:04:39.280 +is uh done in the tangle step versus the + +0:04:37.600,0:04:41.199 +weave step and i'll explain that a + +0:04:39.280,0:04:45.199 +little bit more but the tangle + +0:04:41.199,0:04:48.320 +field just simply tells tells uh + +0:04:45.199,0:04:50.320 +emacs where it needs to generate the + +0:04:48.320,0:04:53.280 +main.go file and where it needs to put + +0:04:50.320,0:04:53.280 +it on the file system + +0:04:55.360,0:04:59.040 +uh you'll you'll notice that we we're + +0:04:57.680,0:05:01.440 +going to use go + +0:04:59.040,0:05:02.160 +that's just the language that i've been + +0:05:01.440,0:05:05.360 +using + +0:05:02.160,0:05:07.360 +the most lately uh but + +0:05:05.360,0:05:08.400 +this programming strategy is language + +0:05:07.360,0:05:12.080 +agnostic + +0:05:08.400,0:05:14.720 +you could use any language or any mix + +0:05:12.080,0:05:16.560 +of languages you could create some files + +0:05:14.720,0:05:19.520 +in python some files and go + +0:05:16.560,0:05:21.520 +some files in in lisp or whatever you + +0:05:19.520,0:05:24.720 +want + +0:05:21.520,0:05:28.000 +and so but let's + +0:05:24.720,0:05:29.440 +uh let's create just a little hello + +0:05:28.000,0:05:32.320 +world + +0:05:29.440,0:05:33.520 +let's use another snippet here to + +0:05:32.320,0:05:36.560 +generate + +0:05:33.520,0:05:39.840 +the basics of a go program + +0:05:36.560,0:05:39.840 +so i'm just going to print + +0:05:40.240,0:05:42.960 +hello world + +0:05:44.960,0:05:48.240 +so that's and then + +0:05:48.560,0:05:55.280 +let's make it a section in our + +0:05:52.320,0:05:56.400 +file so now you can see we've got this + +0:05:55.280,0:05:59.600 +snippet + +0:05:56.400,0:06:01.600 +um when you have a source block in + +0:05:59.600,0:06:02.880 +inside of org mode you can easily pop + +0:06:01.600,0:06:04.960 +into a + +0:06:02.880,0:06:07.680 +language specific buffer by typing + +0:06:04.960,0:06:10.240 +control c single quote + +0:06:07.680,0:06:12.160 +so you can see now i have a a go a + +0:06:10.240,0:06:14.240 +buffer that's in go mode + +0:06:12.160,0:06:15.520 +and gives you all the ability to edit + +0:06:14.240,0:06:18.800 +like you would + +0:06:15.520,0:06:20.800 +normally if you hit ctrl c + +0:06:18.800,0:06:22.639 +single quote again then it goes back and + +0:06:20.800,0:06:25.280 +any changes you + +0:06:22.639,0:06:26.160 +make would will be updated there but you + +0:06:25.280,0:06:28.000 +can do quite a bit + +0:06:26.160,0:06:29.199 +just inside of here too there's quite a + +0:06:28.000,0:06:32.400 +bit of + +0:06:29.199,0:06:32.400 +language specific + +0:06:33.360,0:06:36.880 +functionality just in place and so you + +0:06:35.440,0:06:38.080 +don't always have to go over to a + +0:06:36.880,0:06:42.319 +separate buffer + +0:06:38.080,0:06:44.319 +but it's a it's a nice option sometimes + +0:06:42.319,0:06:46.720 +but now that you have the code in here + +0:06:44.319,0:06:48.560 +you're going to want to run it + +0:06:46.720,0:06:50.240 +but right now it just lives here in this + +0:06:48.560,0:06:52.160 +documentation + +0:06:50.240,0:06:53.840 +so you need to get a copy of it into a + +0:06:52.160,0:06:57.440 +separate file + +0:06:53.840,0:07:01.360 +and that's the tangle process that you + +0:06:57.440,0:07:03.360 +you need to follow there so i'm gonna + +0:07:01.360,0:07:05.280 +drop in a little bit more doc a little + +0:07:03.360,0:07:08.960 +bit more + +0:07:05.280,0:07:08.960 +documentation really quick here + +0:07:12.240,0:07:21.520 +okay all right so just kind of as a + +0:07:17.360,0:07:24.800 +kind of as a side note i like to follow + +0:07:21.520,0:07:26.639 +this process uh whenever having whenever + +0:07:24.800,0:07:28.880 +i have an operation to perform i + +0:07:26.639,0:07:31.680 +i'd like to document it here with a + +0:07:28.880,0:07:33.280 +snippet that can be executed in line + +0:07:31.680,0:07:34.639 +then i don't have to leave org mode and + +0:07:33.280,0:07:36.800 +i don't have to try to remember what i + +0:07:34.639,0:07:38.960 +did later so instead of just + +0:07:36.800,0:07:40.319 +trying to do an operation the first time + +0:07:38.960,0:07:41.680 +i do something i take the + +0:07:40.319,0:07:43.440 +take the time to figure out what it is + +0:07:41.680,0:07:44.879 +and document it and so then it's + +0:07:43.440,0:07:48.400 +recorded + +0:07:44.879,0:07:49.120 +and so here we find that to do a tangle + +0:07:48.400,0:07:51.680 +operation + +0:07:49.120,0:07:52.560 +you run the command or babel tangled + +0:07:51.680,0:07:55.840 +which is a + +0:07:52.560,0:07:59.199 +e-list command so if you hit ctrl c + +0:07:55.840,0:08:00.080 +ctrl c to run it in place you get the + +0:07:59.199,0:08:02.720 +result + +0:08:00.080,0:08:03.759 +of main dot go which basically is + +0:08:02.720,0:08:07.680 +telling us that + +0:08:03.759,0:08:11.039 +we've tangled one file called main.go + +0:08:07.680,0:08:14.000 +and you can see that that's true + +0:08:11.039,0:08:14.400 +if you go to the file system and you + +0:08:14.000,0:08:17.840 +look + +0:08:14.400,0:08:20.960 +so now in uh in our demo directory + +0:08:17.840,0:08:22.479 +we have a readme.org we have that png + +0:08:20.960,0:08:23.440 +that we generated but we also have a + +0:08:22.479,0:08:26.080 +main.go + +0:08:23.440,0:08:27.759 +and if you if you visit that file you'll + +0:08:26.080,0:08:29.280 +see that it's just the source code that + +0:08:27.759,0:08:31.039 +was in our documentation which is + +0:08:29.280,0:08:32.880 +exactly what we expected and what we + +0:08:31.039,0:08:36.000 +wanted so that's good + +0:08:32.880,0:08:36.000 +so if we return to + +0:08:36.560,0:08:39.919 +to where we are at + +0:08:41.120,0:08:44.640 +now we're we're at the point where we + +0:08:42.959,0:08:45.760 +have a file on the file system so now we + +0:08:44.640,0:08:48.959 +need + +0:08:45.760,0:08:53.600 +um now we need to build it and to + +0:08:48.959,0:08:57.040 +run it so let's follow the same + +0:08:53.600,0:08:58.720 +philosophy where let's document + +0:08:57.040,0:09:00.160 +these operations that we're going to + +0:08:58.720,0:09:03.920 +perform + +0:09:00.160,0:09:03.920 +so i'm dropping in a + +0:09:04.560,0:09:11.200 +a build instruction section and a run + +0:09:07.839,0:09:11.200 +instruction section + +0:09:13.360,0:09:17.839 +so as you can see here we have a little + +0:09:15.279,0:09:20.000 +a bash source block + +0:09:17.839,0:09:22.000 +and another batch source block this one + +0:09:20.000,0:09:25.440 +compiles the go build command is what + +0:09:22.000,0:09:26.880 +compiles a file and then + +0:09:25.440,0:09:29.519 +the file that gets generated should be + +0:09:26.880,0:09:29.519 +called demo + +0:09:30.080,0:09:34.000 +and uh so we just run it here so if if i + +0:09:32.959,0:09:37.839 +type control c + +0:09:34.000,0:09:40.640 +control c we get an empty results block + +0:09:37.839,0:09:41.360 +when you compile things no news is good + +0:09:40.640,0:09:44.399 +news + +0:09:41.360,0:09:46.560 +so it means there's no errors so + +0:09:44.399,0:09:48.000 +presumably we've created an executable + +0:09:46.560,0:09:51.440 +that's called demo + +0:09:48.000,0:09:54.560 +so let's uh + +0:09:51.440,0:09:57.519 +let's look again at the file system and + +0:09:54.560,0:09:57.519 +regenerate + +0:10:02.480,0:10:07.200 +yep and what we have here is a demo + +0:10:05.760,0:10:07.760 +executable which is exactly what we + +0:10:07.200,0:10:12.079 +wanted + +0:10:07.760,0:10:14.160 +so let's go back + +0:10:12.079,0:10:16.079 +so now we should be able to run it so + +0:10:14.160,0:10:20.320 +ctrl c ctrl c + +0:10:16.079,0:10:20.320 +and we get hello world as a result + +0:10:20.399,0:10:26.560 +which was exactly what we were expecting + +0:10:23.440,0:10:30.240 +so that's already pretty cool + +0:10:26.560,0:10:30.240 +you can you can do that much + +0:10:30.839,0:10:34.560 +um but + +0:10:33.040,0:10:37.839 +that's really just kind of the tip of + +0:10:34.560,0:10:41.040 +the iceberg to uh to really + +0:10:37.839,0:10:43.440 +kind of um + +0:10:41.040,0:10:46.160 +use the more impressive features of + +0:10:43.440,0:10:49.519 +literate programming we need to uh + +0:10:46.160,0:10:49.519 +we need to do a little bit more + +0:10:49.920,0:10:55.519 +so or at least + +0:10:53.200,0:10:56.480 +at least really to get the full benefit + +0:10:55.519,0:10:59.120 +of it then + +0:10:56.480,0:10:59.120 +we need to do + +0:10:59.600,0:11:06.320 +add some sections that will cause uh + +0:11:02.959,0:11:06.720 +emacs to have to to tangle or assemble + +0:11:06.320,0:11:09.760 +this + +0:11:06.720,0:11:13.120 +this file from different pieces so + +0:11:09.760,0:11:16.720 +imagine that we wanted to take this file + +0:11:13.120,0:11:19.120 +and maybe kind of templatize it + +0:11:16.720,0:11:21.279 +so using literature programming syntax + +0:11:19.120,0:11:24.399 +this angle bracket syntax + +0:11:21.279,0:11:29.360 +let's say that we want to create an in + +0:11:24.399,0:11:32.399 +imports section + +0:11:29.360,0:11:35.040 +in a functions section + +0:11:32.399,0:11:36.240 +and then maybe just a main section and + +0:11:35.040,0:11:37.920 +we'll get rid of this + +0:11:36.240,0:11:39.760 +so now you see we've created something + +0:11:37.920,0:11:42.000 +that looks a little bit like a + +0:11:39.760,0:11:42.880 +like a template or a scaffolding or + +0:11:42.000,0:11:46.000 +outline + +0:11:42.880,0:11:48.399 +for what what our file is going to be it + +0:11:46.000,0:11:50.800 +looks a little bit like pseudocode + +0:11:48.399,0:11:52.399 +and what we're going to have literate + +0:11:50.800,0:11:54.800 +programming do + +0:11:52.399,0:11:56.639 +is dynamically insert those things into + +0:11:54.800,0:12:00.079 +those slots + +0:11:56.639,0:12:03.200 +so the first thing we need to do + +0:12:00.079,0:12:08.079 +is so let's create a section + +0:12:03.200,0:12:09.519 +maybe called say hello so we want + +0:12:08.079,0:12:12.720 +we want to add some functionality that + +0:12:09.519,0:12:15.680 +makes our program say hello + +0:12:12.720,0:12:17.600 +so using a different snippet that i have + +0:12:15.680,0:12:20.800 +for creating something + +0:12:17.600,0:12:24.079 +that i call like a literate section + +0:12:20.800,0:12:26.000 +um basically we create a + +0:12:24.079,0:12:27.839 +another source block that's almost the + +0:12:26.000,0:12:31.040 +same as the one for the file but it's + +0:12:27.839,0:12:31.680 +it just has a few differences so say we + +0:12:31.040,0:12:34.160 +want to + +0:12:31.680,0:12:36.639 +drop code into the import section and we + +0:12:34.160,0:12:39.120 +want it to be in go + +0:12:36.639,0:12:40.720 +here we use the same noed no web no + +0:12:39.120,0:12:43.200 +export syntax + +0:12:40.720,0:12:44.560 +but then we've added this no web refs + +0:12:43.200,0:12:48.240 +imports + +0:12:44.560,0:12:51.120 +and this ties that slot + +0:12:48.240,0:12:53.760 +basically to this reference it tells + +0:12:51.120,0:12:56.880 +emacs that when you tangle + +0:12:53.760,0:12:58.240 +we want to stick whatever's in here in + +0:12:56.880,0:13:02.079 +that spot + +0:12:58.240,0:13:03.279 +so you skip the tangle file name section + +0:13:02.079,0:13:04.240 +because you're not actually creating a + +0:13:03.279,0:13:06.160 +file name you're + +0:13:04.240,0:13:07.680 +you're putting information into an + +0:13:06.160,0:13:10.720 +existing file + +0:13:07.680,0:13:13.680 +so here we would just add the fmt + +0:13:10.720,0:13:13.680 +for the imports + +0:13:14.399,0:13:22.240 +so let's add another section for uh + +0:13:18.839,0:13:25.519 +functions and let's create a + +0:13:22.240,0:13:30.240 +let's just create a function called + +0:13:25.519,0:13:32.839 +say hello that + +0:13:30.240,0:13:34.000 +doesn't have any arguments no return + +0:13:32.839,0:13:35.760 +types + +0:13:34.000,0:13:37.440 +all it does is kind of pretty much the + +0:13:35.760,0:13:39.199 +same thing as we did before + +0:13:37.440,0:13:41.360 +just print something but let's just say + +0:13:39.199,0:13:45.760 +hello + +0:13:41.360,0:13:49.519 +emacs comp this time + +0:13:45.760,0:13:51.040 +okay so now we have a function and now + +0:13:49.519,0:13:52.720 +the function won't do anything unless we + +0:13:51.040,0:13:56.000 +invoke it so let's do + +0:13:52.720,0:13:59.920 +one last literate section + +0:13:56.000,0:14:03.519 +called main make that go + +0:13:59.920,0:14:06.399 +source block and then let's + +0:14:03.519,0:14:06.399 +just invoke + +0:14:06.560,0:14:13.360 +that that function + +0:14:10.320,0:14:15.600 +so now you can see that we've got + +0:14:13.360,0:14:17.199 +our scaffolding scaffolding kind of + +0:14:15.600,0:14:20.079 +outline and then we have + +0:14:17.199,0:14:21.360 +the sections that we want to get tangled + +0:14:20.079,0:14:25.440 +or inserted + +0:14:21.360,0:14:27.199 +so i i've kind of used this syntax + +0:14:25.440,0:14:28.560 +it's it's kind of borrowed from + +0:14:27.199,0:14:30.320 +literature programming a little bit with + +0:14:28.560,0:14:32.480 +a plus equals so really it's just saying + +0:14:30.320,0:14:35.760 +that i want to append + +0:14:32.480,0:14:37.600 +this item into the import section so + +0:14:35.760,0:14:39.839 +it's really just to make a little bit + +0:14:37.600,0:14:41.519 +more clear what's going on + +0:14:39.839,0:14:43.519 +when you generate documentation you + +0:14:41.519,0:14:46.160 +won't see these + +0:14:43.519,0:14:49.360 +these these particular property + +0:14:46.160,0:14:51.440 +annotations and so you won't know + +0:14:49.360,0:14:53.839 +immediately that this section goes in + +0:14:51.440,0:14:55.440 +the imports area and so i usually put + +0:14:53.839,0:14:57.760 +a little bit of documentation on top + +0:14:55.440,0:15:01.120 +there so that it's easy to see + +0:14:57.760,0:15:03.040 +and you would probably if this was very + +0:15:01.120,0:15:06.399 +complicated you'd put some + +0:15:03.040,0:15:07.360 +documentation above to explain what you + +0:15:06.399,0:15:10.320 +were doing + +0:15:07.360,0:15:10.320 +maybe right here + +0:15:11.519,0:15:15.040 +you could you could picture yourself + +0:15:13.279,0:15:17.440 +maybe explaining + +0:15:15.040,0:15:18.079 +a complicated algorithm or something up + +0:15:17.440,0:15:21.120 +here + +0:15:18.079,0:15:22.959 +and having a nice way to document it + +0:15:21.120,0:15:25.600 +so now that we've got that here in the + +0:15:22.959,0:15:27.040 +documentation we need to figure out + +0:15:25.600,0:15:29.920 +we need to make sure that it's going to + +0:15:27.040,0:15:33.519 +tangle properly so your best friend + +0:15:29.920,0:15:35.680 +at this point is is uh + +0:15:33.519,0:15:38.240 +is a keyboard shortcut that lets you + +0:15:35.680,0:15:38.959 +preview the tangled operation so if you + +0:15:38.240,0:15:42.560 +say control + +0:15:38.959,0:15:45.120 +c control v control v + +0:15:42.560,0:15:46.480 +it will create a new buffer with the + +0:15:45.120,0:15:49.360 +tangled + +0:15:46.480,0:15:50.639 +contents and so you can see here that + +0:15:49.360,0:15:53.199 +the fmt + +0:15:50.639,0:15:54.720 +import went to the right place that + +0:15:53.199,0:15:56.160 +function went to the right place the + +0:15:54.720,0:15:58.480 +function invocation went to the right + +0:15:56.160,0:16:01.279 +place and so we're feeling good + +0:15:58.480,0:16:02.800 +you can nest these things many layers + +0:16:01.279,0:16:04.800 +deep + +0:16:02.800,0:16:07.199 +actually so like if you came into the + +0:16:04.800,0:16:10.160 +say hello function you could add + +0:16:07.199,0:16:10.160 +more sections + +0:16:10.560,0:16:13.759 +you know and it gets and it'll go + +0:16:12.160,0:16:15.680 +through and it'll + +0:16:13.759,0:16:16.959 +keep track of all that and tangle it for + +0:16:15.680,0:16:18.320 +you so you really get a lot of freedom + +0:16:16.959,0:16:19.600 +and flexibility for how you want to + +0:16:18.320,0:16:22.320 +document things + +0:16:19.600,0:16:25.839 +by doing this so now that we've + +0:16:22.320,0:16:28.639 +previewed it and we feel good about it + +0:16:25.839,0:16:31.440 +we need to uh we need to tangle so we + +0:16:28.639,0:16:34.480 +get the file on the file system + +0:16:31.440,0:16:37.199 +so ctrl c ctrl c and + +0:16:34.480,0:16:37.920 +get just main.go comes back again + +0:16:37.199,0:16:40.959 +control c + +0:16:37.920,0:16:43.839 +control c and no errors come back + +0:16:40.959,0:16:45.600 +and then if we did this right when we + +0:16:43.839,0:16:47.199 +when we run this we should get hello + +0:16:45.600,0:16:51.199 +emacs comp so ctrl c + +0:16:47.199,0:16:54.800 +ctrl c hello emacs comp + +0:16:51.199,0:16:57.120 +so i uh + +0:16:54.800,0:16:58.240 +i think that's pretty pretty cool + +0:16:57.120,0:17:00.160 +actually so we've got + +0:16:58.240,0:17:02.399 +kind of the breadcrumbs of the process + +0:17:00.160,0:17:05.520 +we've gone through to get to this point + +0:17:02.399,0:17:08.000 +this initial this initial + +0:17:05.520,0:17:09.919 +document that has some tangling in it we + +0:17:08.000,0:17:12.799 +have documentation for how to tangle + +0:17:09.919,0:17:14.079 +how to build how to run it's we've + +0:17:12.799,0:17:17.760 +really built a nice + +0:17:14.079,0:17:20.160 +foundation for + +0:17:17.760,0:17:21.439 +moving forward on our project and a nice + +0:17:20.160,0:17:23.280 +way of breaking things out and + +0:17:21.439,0:17:27.120 +documenting further + +0:17:23.280,0:17:30.559 +the last piece that we need to + +0:17:27.120,0:17:34.799 +take care of is the weave that i + +0:17:30.559,0:17:38.640 +that's i showed you in the diagram above + +0:17:34.799,0:17:41.760 +so one more time we'll drop in + +0:17:38.640,0:17:42.400 +some documentation so this time on how + +0:17:41.760,0:17:44.400 +to weave + +0:17:42.400,0:17:47.520 +so it's really just an export function + +0:17:44.400,0:17:49.280 +it's not there's not a separate weave + +0:17:47.520,0:17:50.640 +command going on here we're just going + +0:17:49.280,0:17:52.799 +to export + +0:17:50.640,0:17:55.200 +what we've got here into a markdown + +0:17:52.799,0:17:57.440 +format so we're using org + +0:17:55.200,0:17:58.880 +gfm export to markdown which is the + +0:17:57.440,0:18:02.160 +github style + +0:17:58.880,0:18:05.440 +markdown you can use the other just + +0:18:02.160,0:18:10.320 +more standard type as well so hit ctrl c + +0:18:05.440,0:18:15.280 +ctrl c now you see we've got a readme + +0:18:10.320,0:18:17.440 +file and if you look + +0:18:15.280,0:18:19.120 +in the file system we've got that right + +0:18:17.440,0:18:23.120 +there and so + +0:18:19.120,0:18:29.840 +if you go to something like ghostwriter + +0:18:23.120,0:18:29.840 +and open that file + +0:18:31.679,0:18:35.520 +now you can see that it's generated some + +0:18:34.559,0:18:38.320 +documentation + +0:18:35.520,0:18:39.679 +it puts a index at top at the top i + +0:18:38.320,0:18:42.000 +usually just + +0:18:39.679,0:18:43.679 +i usually turn that off it's easy to do + +0:18:42.000,0:18:44.559 +that by putting a property at the top of + +0:18:43.679,0:18:46.880 +your + +0:18:44.559,0:18:48.559 +your org file but some people like to + +0:18:46.880,0:18:50.799 +have an index + +0:18:48.559,0:18:52.160 +but here you can see that it's generated + +0:18:50.799,0:18:55.200 +pretty nicely and + +0:18:52.160,0:18:56.880 +formatted snippets well + +0:18:55.200,0:18:58.240 +put the diagram in there and then it's + +0:18:56.880,0:19:01.039 +preserved + +0:18:58.240,0:19:02.799 +it's preserved this literate programming + +0:19:01.039,0:19:04.960 +syntax + +0:19:02.799,0:19:06.480 +which is important because that's how we + +0:19:04.960,0:19:07.200 +want to view the documentation that's + +0:19:06.480,0:19:10.559 +what the no + +0:19:07.200,0:19:13.360 +exports um + +0:19:10.559,0:19:14.000 +property was was trying to maintain so + +0:19:13.360,0:19:16.080 +that + +0:19:14.000,0:19:18.400 +no exports means when you export do not + +0:19:16.080,0:19:20.559 +try to tangle so that's + +0:19:18.400,0:19:22.240 +hopefully that makes more sense now but + +0:19:20.559,0:19:26.080 +now you can see all the documentation + +0:19:22.240,0:19:29.919 +and i think it demonstrates a + +0:19:26.080,0:19:33.520 +pretty useful feature that's inside of + +0:19:29.919,0:19:35.039 +emacs and and hopefully + +0:19:33.520,0:19:39.840 +hopefully you'll have as much fun using + +0:19:35.039,0:19:39.840 +that as i have + +0:19:39.919,0:19:43.600 +so thanks + diff --git

the the + +0:00:35.680,0:00:40.079 +reason of the talk today and the reason + +0:00:38.960,0:00:42.719 +i'm here today + +0:00:40.079,0:00:44.000 +is to talk about my experience in moving + +0:00:42.719,0:00:47.200 +from jekyll uh + +0:00:44.000,0:00:49.200 +static website generator to org mode and + +0:00:47.200,0:00:52.079 +the reason + +0:00:49.200,0:00:53.039 +i move to work mode is to have better + +0:00:52.079,0:00:56.800 +support for + +0:00:53.039,0:00:58.399 +literary programming on the websites + +0:00:56.800,0:01:00.480 +at the university of trento where we + +0:00:58.399,0:01:04.720 +make available the content for the + +0:01:00.480,0:01:08.000 +the students okay so + +0:01:04.720,0:01:10.080 +first of all what is a static website + +0:01:08.000,0:01:11.360 +generator it is basically a tool which + +0:01:10.080,0:01:15.360 +allows you to + +0:01:11.360,0:01:17.439 +generate html files out of text files + +0:01:15.360,0:01:19.280 +containing basically two types of + +0:01:17.439,0:01:23.119 +information metadata + +0:01:19.280,0:01:26.159 +and content metadata is let's say a + +0:01:23.119,0:01:28.560 +set of key pairs describing the the + +0:01:26.159,0:01:30.000 +content of the file such as the title + +0:01:28.560,0:01:31.759 +author + +0:01:30.000,0:01:34.560 +tags and so on and so forth and the + +0:01:31.759,0:01:37.040 +content is what you actually want to to + +0:01:34.560,0:01:38.880 +get published on the on the internet in + +0:01:37.040,0:01:41.439 +the html file + +0:01:38.880,0:01:44.240 +and usually the content is written in + +0:01:41.439,0:01:44.240 +some kind of + +0:01:44.560,0:01:49.759 +markup language such as markdown or + +0:01:47.520,0:01:53.200 +possibly + +0:01:49.759,0:01:55.759 +org mode and well jackie is a very + +0:01:53.200,0:01:58.719 +popular website uh + +0:01:55.759,0:01:59.840 +a static website generator it is written + +0:01:58.719,0:02:03.280 +in a ruby + +0:01:59.840,0:02:06.840 +and what it does it it it systematically + +0:02:03.280,0:02:09.440 +let's say transforms all the input files + +0:02:06.840,0:02:11.599 +by making the content into + +0:02:09.440,0:02:14.000 +html and systematically applying a + +0:02:11.599,0:02:17.120 +template in order to generate the + +0:02:14.000,0:02:19.840 +html files which you can then deploy + +0:02:17.120,0:02:22.160 +on your server of choice to make them + +0:02:19.840,0:02:26.160 +available on the on the internet + +0:02:22.160,0:02:28.480 +and one of the features uh most + +0:02:26.160,0:02:30.239 +well i would say all static website + +0:02:28.480,0:02:32.560 +generators have + +0:02:30.239,0:02:34.879 +is a debt of being able to let's say + +0:02:32.560,0:02:38.400 +collect the metadata information + +0:02:34.879,0:02:39.440 +uh of the files being part of your of + +0:02:38.400,0:02:45.280 +your project + +0:02:39.440,0:02:47.840 +and the reason they do that is because + +0:02:45.280,0:02:49.280 +you sometimes want to generate pages + +0:02:47.840,0:02:53.200 +based on the content + +0:02:49.280,0:02:56.239 +of your um of your projects + +0:02:53.200,0:02:59.040 +such as for instance the the list of + +0:02:56.239,0:03:00.400 +posts you have recently published or + +0:02:59.040,0:03:03.840 +maybe the list of tags + +0:03:00.400,0:03:07.280 +uh you uh have defined for your post and + +0:03:03.840,0:03:09.760 +so on and so forth so so + +0:03:07.280,0:03:12.400 +dracula gives the possibility of + +0:03:09.760,0:03:15.760 +generating this kind of dynamic + +0:03:12.400,0:03:18.800 +content by using liquid which is a + +0:03:15.760,0:03:21.840 +templating language which + +0:03:18.800,0:03:24.879 +looks like these + +0:03:21.840,0:03:26.879 +so basically you you have all the + +0:03:24.879,0:03:29.120 +constructs you can + +0:03:26.879,0:03:29.920 +expect in a programming language this + +0:03:29.120,0:03:33.360 +for instance + +0:03:29.920,0:03:37.440 +is a fourth cycle which + +0:03:33.360,0:03:39.599 +iterates over all the post or the + +0:03:37.440,0:03:41.040 +files in a specific directory of the + +0:03:39.599,0:03:45.040 +jacket project + +0:03:41.040,0:03:48.400 +and for each post it takes the the title + +0:03:45.040,0:03:51.840 +and the url and generates a link + +0:03:48.400,0:03:55.200 +okay so dracule is + +0:03:51.840,0:03:57.760 +nice and sweet but over the years + +0:03:55.200,0:03:59.519 +i started using more and more + +0:03:57.760,0:04:02.959 +systematically + +0:03:59.519,0:04:05.439 +or mode to write all my files and i + +0:04:02.959,0:04:07.439 +moved from markdown to word mode i am a + +0:04:05.439,0:04:09.680 +long time emacs user so i've been using + +0:04:07.439,0:04:12.799 +imax for 30 years now so + +0:04:09.680,0:04:15.280 +or mode is a more recent discovery + +0:04:12.799,0:04:16.239 +but it is a very nice uh let's say + +0:04:15.280,0:04:19.680 +discovery i + +0:04:16.239,0:04:22.320 +i made and the reason i like org mode + +0:04:19.680,0:04:23.600 +is because for instance you can write + +0:04:22.320,0:04:26.639 +formulas using + +0:04:23.600,0:04:30.320 +mac jacks and you can generate diagrams + +0:04:26.639,0:04:32.240 +or plots with new plots and + +0:04:30.320,0:04:34.080 +also important is the fact that you have + +0:04:32.240,0:04:35.919 +the possibility of let's say publishing + +0:04:34.080,0:04:39.520 +your documents + +0:04:35.919,0:04:40.400 +to multiple ends backhands such as pdf + +0:04:39.520,0:04:43.600 +or + +0:04:40.400,0:04:47.199 +maybe a review presentations or + +0:04:43.600,0:04:50.479 +or html and this is all made possible + +0:04:47.199,0:04:52.560 +by bubble which is + +0:04:50.479,0:04:54.639 +exactly what we just saw in the the + +0:04:52.560,0:04:57.440 +previous talk + +0:04:54.639,0:04:59.520 +namely the possibility of executing a + +0:04:57.440,0:05:02.560 +snippet of code + +0:04:59.520,0:05:06.400 +embedded in in your pages + +0:05:02.560,0:05:09.600 +um and our model can also be used + +0:05:06.400,0:05:10.720 +within let's say jackie and in fact + +0:05:09.600,0:05:15.199 +there is a + +0:05:10.720,0:05:18.880 +a nice gem a nice library called jackie + +0:05:15.199,0:05:19.680 +org which allows you to use org modifies + +0:05:18.880,0:05:22.880 +directly + +0:05:19.680,0:05:26.560 +into jekyll but when you start using + +0:05:22.880,0:05:30.560 +org mode when i started using + +0:05:26.560,0:05:34.240 +mode i realized i could move + +0:05:30.560,0:05:36.840 +all my workflow to or my publishing + +0:05:34.240,0:05:39.520 +workflow to image + +0:05:36.840,0:05:41.600 +and and and in fact + +0:05:39.520,0:05:42.880 +org mode is also static website + +0:05:41.600,0:05:46.240 +generator because + +0:05:42.880,0:05:50.880 +it has got the possibility of publishing + +0:05:46.240,0:05:53.840 +um projects made of org mode files + +0:05:50.880,0:05:55.759 +and one of the nice things about let's + +0:05:53.840,0:05:56.479 +say that the publishing features of work + +0:05:55.759,0:05:58.880 +mode + +0:05:56.479,0:05:59.840 +is that it allows you to define in the + +0:05:58.880,0:06:03.199 +org publish + +0:05:59.840,0:06:06.479 +project a list of the components + +0:06:03.199,0:06:07.520 +which are part of your project and in a + +0:06:06.479,0:06:10.479 +sense it is + +0:06:07.520,0:06:12.400 +also more flexible than jackie lee's + +0:06:10.479,0:06:12.880 +because it also allows you for instance + +0:06:12.400,0:06:15.120 +to + +0:06:12.880,0:06:17.440 +let's say publish a single file rather + +0:06:15.120,0:06:20.080 +than having to recompile everything + +0:06:17.440,0:06:23.919 +every time you want to publish your + +0:06:20.080,0:06:25.840 +your project to your website however + +0:06:23.919,0:06:27.120 +there are some short comments i would + +0:06:25.840,0:06:29.520 +say or some some + +0:06:27.120,0:06:30.400 +areas of improvement improvement let me + +0:06:29.520,0:06:32.720 +say + +0:06:30.400,0:06:33.600 +the first is that let's say support for + +0:06:32.720,0:06:36.639 +templating + +0:06:33.600,0:06:39.280 +is not so obvious as it is let's say + +0:06:36.639,0:06:40.560 +in jackie or even though there are some + +0:06:39.280,0:06:44.560 +let's say + +0:06:40.560,0:06:46.160 +nice extensions such as argo t html + +0:06:44.560,0:06:48.400 +for instance which allows you to use + +0:06:46.160,0:06:51.840 +templates and + +0:06:48.400,0:06:54.080 +more important to me was the fact that + +0:06:51.840,0:06:55.520 +apparently there is little support for + +0:06:54.080,0:06:58.240 +the creation of dynamic + +0:06:55.520,0:06:59.360 +content so i was very curious and very + +0:06:58.240,0:07:02.800 +keen to use + +0:06:59.360,0:07:05.440 +or mode for let's say publishing my blog + +0:07:02.800,0:07:08.720 +and my the the courses at the university + +0:07:05.440,0:07:11.440 +but then uh i had to find a way + +0:07:08.720,0:07:13.599 +to let's say being able to publish these + +0:07:11.440,0:07:16.000 +dynamic pages finding some kind of + +0:07:13.599,0:07:16.720 +replacement so to speak for uh the + +0:07:16.000,0:07:19.759 +liquid + +0:07:16.720,0:07:20.160 +the liquid engine and and the solution + +0:07:19.759,0:07:24.160 +was + +0:07:20.160,0:07:27.280 +that at hand actually because + +0:07:24.160,0:07:30.800 +basically i realized i could use bubble + +0:07:27.280,0:07:32.720 +for exactly this purpose so rather than + +0:07:30.800,0:07:35.759 +using bubble for generating + +0:07:32.720,0:07:37.919 +plots or let's say my other computation + +0:07:35.759,0:07:41.039 +or whatever i was using them for + +0:07:37.919,0:07:42.080 +i realized they could use bubble to + +0:07:41.039,0:07:45.120 +generate + +0:07:42.080,0:07:48.960 +html which could be let's say + +0:07:45.120,0:07:52.720 +uh then published uh uh + +0:07:48.960,0:07:53.680 +in the project so uh so all i needed to + +0:07:52.720,0:07:56.240 +do then + +0:07:53.680,0:07:58.319 +was defining some kind of functions some + +0:07:56.240,0:08:01.840 +kind of code in order to read + +0:07:58.319,0:08:02.400 +all the org mode uh the metadata of all + +0:08:01.840,0:08:05.759 +the + +0:08:02.400,0:08:09.680 +opmod files of my web project so that + +0:08:05.759,0:08:13.280 +i could let's say then publish uh + +0:08:09.680,0:08:17.440 +generate the dynamic content and + +0:08:13.280,0:08:17.440 +this is a snippet taken from + +0:08:18.080,0:08:24.800 +one of my html projects + +0:08:21.759,0:08:27.599 +which basically shows the way in which + +0:08:24.800,0:08:29.360 +i generate the um the list of posts on + +0:08:27.599,0:08:32.560 +my on my page it is uh + +0:08:29.360,0:08:34.320 +exactly how the the liquid that we saw + +0:08:32.560,0:08:35.680 +in a couple of a couple of slides + +0:08:34.320,0:08:39.200 +earlier that looks like + +0:08:35.680,0:08:42.320 +uh in inner mode + +0:08:39.200,0:08:46.720 +and basically what i'm doing i'm using i + +0:08:42.320,0:08:49.680 +wrote a ruby script which + +0:08:46.720,0:08:51.040 +reads all the metadata so this uh + +0:08:49.680,0:08:53.440 +highlighted code + +0:08:51.040,0:08:54.240 +basically loads the script which is + +0:08:53.440,0:08:56.800 +stored + +0:08:54.240,0:08:58.320 +externally and then it collects all the + +0:08:56.800,0:09:00.880 +metadata from the + +0:08:58.320,0:09:02.240 +org mode files in the current uh in the + +0:09:00.880,0:09:04.800 +current directory + +0:09:02.240,0:09:06.480 +and then the the following the the code + +0:09:04.800,0:09:09.839 +you can see here + +0:09:06.480,0:09:12.959 +basically iterate over all the + +0:09:09.839,0:09:16.399 +past red the at the previous step + +0:09:12.959,0:09:19.519 +and it generates um + +0:09:16.399,0:09:22.959 +a list with the title and uh + +0:09:19.519,0:09:27.440 +and the urls and so basically + +0:09:22.959,0:09:30.240 +replicating what jackie does so + +0:09:27.440,0:09:32.399 +okay so there are some some other things + +0:09:30.240,0:09:33.200 +i have to to deal with in order to let's + +0:09:32.399,0:09:36.480 +say + +0:09:33.200,0:09:39.200 +accommodate my workflow and but that was + +0:09:36.480,0:09:40.240 +relatively easy in the sense that one of + +0:09:39.200,0:09:43.279 +the + +0:09:40.240,0:09:45.360 +uh problem one of the issue i had to + +0:09:43.279,0:09:48.480 +solve was that of let's say having + +0:09:45.360,0:09:51.040 +a common navigation on all my + +0:09:48.480,0:09:51.920 +pages uh but that was easily solved + +0:09:51.040,0:09:54.959 +using + +0:09:51.920,0:09:56.000 +uh the include feature so i basically + +0:09:54.959,0:09:57.839 +made available + +0:09:56.000,0:10:00.560 +and include with all the navigation + +0:09:57.839,0:10:01.839 +which is uh embedded in all the pages of + +0:10:00.560,0:10:04.959 +my websites + +0:10:01.839,0:10:06.160 +uh through the could include and another + +0:10:04.959,0:10:08.560 +nice feature which + +0:10:06.160,0:10:09.760 +jackie las is the possibility of + +0:10:08.560,0:10:12.800 +previewing + +0:10:09.760,0:10:13.200 +a website before deploying it and but + +0:10:12.800,0:10:16.079 +then + +0:10:13.200,0:10:17.839 +emacs also has got a node which allows + +0:10:16.079,0:10:21.200 +you to + +0:10:17.839,0:10:24.320 +launch a web server and in fact + +0:10:21.200,0:10:26.959 +i wrote a quick ack + +0:10:24.320,0:10:28.000 +which allows you to which allows to + +0:10:26.959,0:10:31.519 +basically + +0:10:28.000,0:10:34.720 +invoke a node on a on our + +0:10:31.519,0:10:37.920 +mode project and start a local preview + +0:10:34.720,0:10:43.680 +and then use rsync + +0:10:37.920,0:10:43.680 +in order to deploy the the website + +0:10:44.839,0:10:48.720 +um + +0:10:46.240,0:10:51.200 +five minutes left okay okay more than + +0:10:48.720,0:10:53.200 +enough okay + +0:10:51.200,0:10:55.440 +thanks thank you thank you very much i'm + +0:10:53.200,0:10:56.480 +nearly done so then i can take some some + +0:10:55.440,0:11:00.560 +questions + +0:10:56.480,0:11:03.680 +so okay just to give you maybe + +0:11:00.560,0:11:06.480 +a slightly more in-depth uh + +0:11:03.680,0:11:07.200 +view of what the pages look like so + +0:11:06.480,0:11:11.120 +these are + +0:11:07.200,0:11:14.720 +one of the pages or the source files + +0:11:11.120,0:11:18.480 +of one of the websites it is + +0:11:14.720,0:11:20.399 +in literate programming so basically uh + +0:11:18.480,0:11:22.640 +you see there is some metadata here i + +0:11:20.399,0:11:26.640 +mean this is a regular old mod file + +0:11:22.640,0:11:29.920 +and this part here + +0:11:26.640,0:11:31.519 +basically defines some common options + +0:11:29.920,0:11:35.920 +for publication + +0:11:31.519,0:11:41.120 +and these two includes here + +0:11:35.920,0:11:44.480 +put some extra html in the head part and + +0:11:41.120,0:11:48.079 +the navigation and here as you can see + +0:11:44.480,0:11:50.160 +is the code generating the + +0:11:48.079,0:11:52.240 +the list in chronological order it is + +0:11:50.160,0:11:53.839 +slightly more complex than the example i + +0:11:52.240,0:11:56.240 +made in the slide + +0:11:53.839,0:11:57.839 +because uh there is some more + +0:11:56.240,0:11:59.760 +elaboration to + +0:11:57.839,0:12:01.839 +uh to do including putting some + +0:11:59.760,0:12:05.120 +javascript to identify + +0:12:01.839,0:12:08.160 +according to let's say the the tags + +0:12:05.120,0:12:11.200 +so to go back to the to the presentation + +0:12:08.160,0:12:13.600 +um so the okay so + +0:12:11.200,0:12:14.560 +i i managed this migration uh a few + +0:12:13.600,0:12:17.680 +months ago + +0:12:14.560,0:12:20.399 +and then uh all my workflow is within + +0:12:17.680,0:12:23.079 +with old mode and within imax and um + +0:12:20.399,0:12:24.240 +i'm very happy with it because it's + +0:12:23.079,0:12:26.800 +simplified + +0:12:24.240,0:12:28.480 +uh quite a bit let's say my public + +0:12:26.800,0:12:31.839 +publication process + +0:12:28.480,0:12:34.240 +and uh one of the advantages so another + +0:12:31.839,0:12:36.959 +advantage so the first advantage is that + +0:12:34.240,0:12:38.160 +everything is in ork mode and dmax + +0:12:36.959,0:12:41.680 +second advantage + +0:12:38.160,0:12:44.880 +is that everything is based on the + +0:12:41.680,0:12:47.760 +standard machinery provided by orb mode + +0:12:44.880,0:12:50.079 +so in a sense it is kind of let's say + +0:12:47.760,0:12:53.040 +more robust with respect to + +0:12:50.079,0:12:54.320 +dependencies and possible errors and so + +0:12:53.040,0:12:56.639 +on and so forth + +0:12:54.320,0:12:58.240 +and um and the fact that the old mode + +0:12:56.639,0:13:00.880 +allows you to publish + +0:12:58.240,0:13:03.839 +a single file in a project is is also + +0:13:00.880,0:13:07.839 +very interesting because + +0:13:03.839,0:13:11.040 +it allows to let's say be more robust to + +0:13:07.839,0:13:14.079 +problems you might introduce when + +0:13:11.040,0:13:14.959 +you're changing when i'm changing the + +0:13:14.079,0:13:16.880 +setup + +0:13:14.959,0:13:18.320 +and another interesting thing which i + +0:13:16.880,0:13:21.519 +realized that i + +0:13:18.320,0:13:23.600 +uh i could have is that + +0:13:21.519,0:13:24.880 +in a sense the specification of the + +0:13:23.600,0:13:27.360 +website + +0:13:24.880,0:13:28.480 +is uh can be embedded in the website + +0:13:27.360,0:13:30.800 +itself + +0:13:28.480,0:13:31.839 +so in a sense this is some kind of let's + +0:13:30.800,0:13:35.120 +say self + +0:13:31.839,0:13:37.200 +the command it's a real set documenting + +0:13:35.120,0:13:38.560 +uh what i'm actually doing so for + +0:13:37.200,0:13:42.800 +instance + +0:13:38.560,0:13:42.800 +uh here on my + +0:13:43.199,0:13:48.240 +website you can see let's say the + +0:13:46.399,0:13:51.519 +specification of the + +0:13:48.240,0:13:52.320 +of the of the project which is uh loaded + +0:13:51.519,0:13:55.519 +from my + +0:13:52.320,0:13:56.320 +initialization file but then it is also + +0:13:55.519,0:13:59.440 +published + +0:13:56.320,0:14:01.360 +together with my home page and it leaves + +0:13:59.440,0:14:05.360 +with the repository where + +0:14:01.360,0:14:08.079 +i keep all the sources of my website + +0:14:05.360,0:14:09.839 +which is kind of nice because it + +0:14:08.079,0:14:14.079 +basically isolates + +0:14:09.839,0:14:16.880 +everything in a single in a single place + +0:14:14.079,0:14:18.000 +okay so there are some examples i'm + +0:14:16.880,0:14:20.320 +showing them + +0:14:18.000,0:14:21.760 +more because of the let's say source + +0:14:20.320,0:14:25.519 +code which + +0:14:21.760,0:14:26.160 +you can grab from the git repositories + +0:14:25.519,0:14:28.399 +if you are + +0:14:26.160,0:14:30.079 +interested of course i'm also available + +0:14:28.399,0:14:32.959 +to provide some + +0:14:30.079,0:14:34.480 +support and help if you are interested + +0:14:32.959,0:14:37.760 +in this kind of stuff + +0:14:34.480,0:14:38.560 +the the next step for me will be that of + +0:14:37.760,0:14:41.600 +let's say trying + +0:14:38.560,0:14:45.199 +making this kind of machinery available + +0:14:41.600,0:14:47.120 +for more general use at the moment + +0:14:45.199,0:14:48.800 +if you are interested in trying out my + +0:14:47.120,0:14:49.839 +suggestion is let's say grabbing the +

the 15 + +0:00:02.480,0:00:05.279 +minutes and i'll take five minutes of + +0:00:03.919,0:00:07.520 +question at the end + +0:00:05.279,0:00:09.200 +so hello again i suppose you're starting + +0:00:07.520,0:00:10.719 +to get pretty familiar with me and my + +0:00:09.200,0:00:12.480 +start right now so + +0:00:10.719,0:00:14.719 +right now we're getting into the nitty + +0:00:12.480,0:00:17.039 +gritty we started today + +0:00:14.719,0:00:18.480 +i told you about how i'd ventured from + +0:00:17.039,0:00:20.800 +being a user + +0:00:18.480,0:00:22.080 +to being a maintainer and right now i'm + +0:00:20.800,0:00:24.240 +going to get the chance to + +0:00:22.080,0:00:25.279 +actually tell you more about the project + +0:00:24.240,0:00:28.480 +that i'm maintaining + +0:00:25.279,0:00:30.560 +which is called org rome + +0:00:28.480,0:00:32.320 +so even if i it would have had a better + +0:00:30.560,0:00:33.840 +impact if i'd + +0:00:32.320,0:00:35.520 +didn't scroll the page but you know + +0:00:33.840,0:00:37.120 +sadly i'm out of tea + +0:00:35.520,0:00:39.600 +it's getting late in europe and i'm + +0:00:37.120,0:00:43.360 +starting to get tired + +0:00:39.600,0:00:46.160 +so what i'm gonna do during this talk + +0:00:43.360,0:00:48.079 +is just to do real survey for people who + +0:00:46.160,0:00:50.480 +do not know what orgrom is about + +0:00:48.079,0:00:52.320 +some of you might might have you know + +0:00:50.480,0:00:54.879 +whilst browsing reddit + +0:00:52.320,0:00:56.480 +found a topic about orgrom and thought + +0:00:54.879,0:00:57.199 +to yourself oh that looks interesting + +0:00:56.480,0:00:59.680 +but + +0:00:57.199,0:01:01.039 +you know i have my own workflow and i + +0:00:59.680,0:01:03.199 +get it don't need to change anything + +0:01:01.039,0:01:05.680 +about it you know i'm completely fine + +0:01:03.199,0:01:07.520 +using my very very large file or i'm + +0:01:05.680,0:01:10.960 +completely fine having my + +0:01:07.520,0:01:14.560 +database of notes which is i've been + +0:01:10.960,0:01:17.759 +accruing for like 10 20 30 years or so + +0:01:14.560,0:01:20.080 +so what i want to do during this talk + +0:01:17.759,0:01:20.960 +is both to present to you what orgrom is + +0:01:20.080,0:01:23.439 +about + +0:01:20.960,0:01:24.000 +if you are in this group of people who + +0:01:23.439,0:01:25.600 +do not + +0:01:24.000,0:01:27.520 +know what algorithm is about but would + +0:01:25.600,0:01:30.560 +like to know more but + +0:01:27.520,0:01:33.360 +also for people who have close to no + +0:01:30.560,0:01:35.040 +experience with emacs and org mode and + +0:01:33.360,0:01:36.880 +was just found their way you know they + +0:01:35.040,0:01:39.840 +wanted to find the system to + +0:01:36.880,0:01:41.439 +write their notes basically and you know + +0:01:39.840,0:01:42.960 +they discovered this little tool which + +0:01:41.439,0:01:44.479 +is called orgrome + +0:01:42.960,0:01:46.240 +and they'd like to know more about this + +0:01:44.479,0:01:49.360 +so i've got 13 + +0:01:46.240,0:01:53.360 +minutes to convince you to use hologram + +0:01:49.360,0:01:56.799 +so if we go in a very broad strokes + +0:01:53.360,0:01:59.759 +what is orgram orgrom + +0:01:56.799,0:02:00.320 +is a way for you to manage backlinks + +0:01:59.759,0:02:03.439 +inside + +0:02:00.320,0:02:07.040 +old mode and the keyword + +0:02:03.439,0:02:10.080 +in what i've just said is links now + +0:02:07.040,0:02:12.879 +there is a principle behind orgrom + +0:02:10.080,0:02:14.239 +which is called the zettelgasten method + +0:02:12.879,0:02:15.440 +which you can see written right there + +0:02:14.239,0:02:18.000 +it's a german word + +0:02:15.440,0:02:19.280 +which means a slit box if you remember + +0:02:18.000,0:02:22.080 +in old libraries + +0:02:19.280,0:02:23.440 +you had actually i believe if i scroll i + +0:02:22.080,0:02:26.640 +should have an example of this + +0:02:23.440,0:02:28.879 +yes so this is a slip box basically in + +0:02:26.640,0:02:30.560 +all libraries you used to have all the + +0:02:28.879,0:02:31.599 +references to the books that the library + +0:02:30.560,0:02:34.720 +used to have + +0:02:31.599,0:02:36.080 +inside those boxes and they're called + +0:02:34.720,0:02:38.480 +slim boxes because you can + +0:02:36.080,0:02:41.200 +insert stuff into the boxes and you can + +0:02:38.480,0:02:44.720 +remove stuff out of the boxes + +0:02:41.200,0:02:48.000 +now basically if i try + +0:02:44.720,0:02:49.360 +to summarize as simply as i may what the + +0:02:48.000,0:02:52.800 +zettel cast method + +0:02:49.360,0:02:56.560 +is about it's about having a way + +0:02:52.800,0:02:59.920 +to work with your notes which considers + +0:02:56.560,0:03:02.000 +elements of knowledge as atoms + +0:02:59.920,0:03:04.159 +so as something that is individual like + +0:03:02.000,0:03:06.640 +a single file + +0:03:04.159,0:03:07.440 +and you consider that in order to build + +0:03:06.640,0:03:10.560 +knowledge + +0:03:07.440,0:03:11.120 +you have to combine atoms together so + +0:03:10.560,0:03:14.720 +that + +0:03:11.120,0:03:17.519 +when you have one atom another atom + +0:03:14.720,0:03:18.879 +if you link them together you have a + +0:03:17.519,0:03:22.000 +complex + +0:03:18.879,0:03:24.000 +thought or a complex molecule + +0:03:22.000,0:03:25.360 +okay don't quote me on the chemistry by + +0:03:24.000,0:03:26.879 +the way i shall remind you i'm an + +0:03:25.360,0:03:28.239 +english major i have no idea what i'm + +0:03:26.879,0:03:31.360 +talking about + +0:03:28.239,0:03:32.000 +so how does it work as far as a + +0:03:31.360,0:03:35.280 +note-taking + +0:03:32.000,0:03:37.599 +system is concerned and to do so + +0:03:35.280,0:03:39.760 +i'm just going to switch really quickly + +0:03:37.599,0:03:43.040 +to my emacs if i + +0:03:39.760,0:03:44.959 +may so i'm just going to screenshot + +0:03:43.040,0:03:47.840 +onto my mac just give me a second to get + +0:03:44.959,0:03:52.080 +the windows all right +

+0:03:56.000,0:04:01.680 +i need to figure this out + +0:03:58.840,0:04:03.120 +okay so everything is frozen right now + +0:04:01.680,0:04:04.720 +just to tell you so you're gonna have to + +0:04:03.120,0:04:06.159 +deal with my lovely voice + +0:04:04.720,0:04:07.920 +uh i mean can you confirm that if i + +0:04:06.159,0:04:09.840 +switch to a new ttr you can still hear +

your + +0:07:38.800,0:07:41.039 +folder + +0:07:39.520,0:07:43.280 +where all your notes are going to be + +0:07:41.039,0:07:44.000 +living so you have here and i hope you + +0:07:43.280,0:07:47.039

+0:07:51.120,0:07:54.240 +as you might have garnered by the fact + +0:07:52.960,0:07:57.039 +that it finishes by + +0:07:54.240,0:07:57.599 +that org is that it is just an old mod + +0:07:57.039,0:08:00.800 +file + +0:07:57.599,0:08:03.520 +so i can create a heading + +0:08:00.800,0:08:05.280 +i can create another heading and + +0:08:03.520,0:08:05.599 +everything works as you would expect it + +0:08:05.280,0:08:08.879 +to + +0:08:05.599,0:08:10.400 +it is completely it's just an awkward + +0:08:08.879,0:08:13.759 +file at the end of the day + +0:08:10.400,0:08:15.840 +so now what can we do with this + +0:08:13.759,0:08:16.800 +now i've told you about links and you do + +0:08:15.840,0:08:19.520 +know that + +0:08:16.800,0:08:20.080 +org mode has links so what we're going + +0:08:19.520,0:08:22.479 +to do + +0:08:20.080,0:08:23.440 +is that we're going to create a new file + +0:08:22.479,0:08:26.240 +so we're going to go back + +0:08:23.440,0:08:28.000 +to our directory and what i'm going to + +0:08:26.240,0:08:28.879 +do is that we have a special commands + +0:08:28.000,0:08:31.199 +actually let me just + +0:08:28.879,0:08:32.240 +show you my command i might help you a + +0:08:31.199,0:08:35.360 +little bit + +0:08:32.240,0:08:36.479 +see what i'm doing uh wait which is the + +0:08:35.360,0:08:39.680 +buffer + +0:08:36.479,0:08:41.039 +uh log mode yes exlog so now on the + +0:08:39.680,0:08:43.120 +right side of the monitor you'll be able + +0:08:41.039,0:08:45.040 +to see the command that i'm using + +0:08:43.120,0:08:46.640 +if you don't mind in order to have as + +0:08:45.040,0:08:48.480 +much realistic as possible i'm going to + +0:08:46.640,0:08:50.720 +make it a little bit shorter + +0:08:48.480,0:08:52.320 +smaller i should say is it not too small + +0:08:50.720,0:08:54.720 +yeah i believe it's good + +0:08:52.320,0:08:55.760 +so what i'm going to do is i'm going to + +0:08:54.720,0:08:57.920 +run a command + +0:08:55.760,0:08:59.200 +in orgrome which allows me to create a + +0:08:57.920,0:09:02.320 +new note + +0:08:59.200,0:09:04.720 +so i'm going to use my keybinding which + +0:09:02.320,0:09:06.800 +is not this one definitely + +0:09:04.720,0:09:08.000 +and i'm going to create a new file which + +0:09:06.800,0:09:09.839 +is in a + +0:09:08.000,0:09:11.680 +great tradition of examples in + +0:09:09.839,0:09:15.519 +programming i'm going to call + +0:09:11.680,0:09:17.600 +foo right so at the bottom + +0:09:15.519,0:09:18.720 +in the bottom buffer i should say you + +0:09:17.600,0:09:21.760 +are seeing the file + +0:09:18.720,0:09:22.720 +foo which is as you can see here a + +0:09:21.760,0:09:24.640 +capture buffer + +0:09:22.720,0:09:25.839 +just like you would have in blog mode + +0:09:24.640,0:09:28.560 +now what i'm going to do + +0:09:25.839,0:09:29.200 +is that i'm going to validate this file + +0:09:28.560,0:09:32.560 +and now + +0:09:29.200,0:09:36.240 +you see that we are in the file foo + +0:09:32.560,0:09:39.440 +and the good thing is that i can start + +0:09:36.240,0:09:42.160 +writing without having to worry + +0:09:39.440,0:09:43.760 +about anything else and i was thinking i + +0:09:42.160,0:09:46.160 +was going to say to say that i'm + +0:09:43.760,0:09:47.680 +showing off about my typing skills but i + +0:09:46.160,0:09:50.959 +did make mistakes so + +0:09:47.680,0:09:53.760 +well nobody's perfect right so now we do + +0:09:50.959,0:09:55.519 +have this view file and we're going to + +0:09:53.760,0:09:56.800 +go back to the index so let's go back to + +0:09:55.519,0:09:58.560 +the directory + +0:09:56.800,0:10:00.000 +we're going to refresh the file as you + +0:09:58.560,0:10:00.560 +can see we have a file which is called + +0:10:00.000,0:10:03.360 +foo + +0:10:00.560,0:10:04.399 +and we have the index so now what i'm + +0:10:03.360,0:10:06.480 +going to do + +0:10:04.399,0:10:07.760 +is that i'm going to insert a link to + +0:10:06.480,0:10:09.920 +this file + +0:10:07.760,0:10:11.360 +so we're going to run another orgrim + +0:10:09.920,0:10:14.160 +command which you can see here + +0:10:11.360,0:10:15.279 +orgrim inset and i'm going to insert a + +0:10:14.160,0:10:17.279 +link to the file + +0:10:15.279,0:10:18.959 +foo and as you can see it has now + +0:10:17.279,0:10:21.920 +appeared now what i'm going to do + +0:10:18.959,0:10:23.040 +i'm going to save the file and now i'm + +0:10:21.920,0:10:24.480 +going to show you + +0:10:23.040,0:10:26.720 +the little thing i told you about + +0:10:24.480,0:10:27.680 +backlinks before so i'm afraid i'm going + +0:10:26.720,0:10:29.680 +to have to hide + +0:10:27.680,0:10:30.880 +the commands for now but don't worry + +0:10:29.680,0:10:33.760 +i'll be back + +0:10:30.880,0:10:34.320 +and i'm going to show you the side + +0:10:33.760,0:10:35.839 +buffer + +0:10:34.320,0:10:38.079 +so it is the buffer that you see on the + +0:10:35.839,0:10:40.000 +right side of your screen + +0:10:38.079,0:10:42.560 +and right now it's telling you that + +0:10:40.000,0:10:45.440 +index does not have any backlink + +0:10:42.560,0:10:46.320 +which is normal but if we follow the + +0:10:45.440,0:10:49.200 +link + +0:10:46.320,0:10:50.560 +fu now you see something different on + +0:10:49.200,0:10:52.160 +the right side so as you can see on the + +0:10:50.560,0:10:53.360 +left side we're back insta inside the + +0:10:52.160,0:10:55.600 +file foo + +0:10:53.360,0:10:56.560 +but on the right side we have something + +0:10:55.600,0:11:00.160 +showing up + +0:10:56.560,0:11:03.519 +one backlink in the file index + +0:11:00.160,0:11:04.399 +in under the heading heading you have + +0:11:03.519,0:11:07.680 +the file + +0:11:04.399,0:11:08.720 +sorry the link foo and you can just open + +0:11:07.680,0:11:10.720 +the link + +0:11:08.720,0:11:12.640 +and you will be brought exactly where it + +0:11:10.720,0:11:16.240 +is so + +0:11:12.640,0:11:17.600 +okay so that was one thing now just + +0:11:16.240,0:11:19.360 +to make sure that you've understood + +0:11:17.600,0:11:20.320 +properly i'm going to go back to the + +0:11:19.360,0:11:23.920 +index + +0:11:20.320,0:11:25.440 +i'm going to create a second file + +0:11:23.920,0:11:27.680 +so now i'm going to use a command that + +0:11:25.440,0:11:30.800 +is slightly different so let me just uh + +0:11:27.680,0:11:32.480 +show you the commands on the right + +0:11:30.800,0:11:33.839 +i'm going to run the command orgrim + +0:11:32.480,0:11:37.519 +insert and i'm going to + +0:11:33.839,0:11:39.600 +end to enter a file which is called bar + +0:11:37.519,0:11:41.440 +so again at the bottom you can see that + +0:11:39.600,0:11:45.920 +i have a new file bar + +0:11:41.440,0:11:49.760 +i'm going to validate this file + +0:11:45.920,0:11:52.959 +okay i'm going to save index.org + +0:11:49.760,0:11:54.320 +and now if we go in bar and if i show + +0:11:52.959,0:11:55.920 +you + +0:11:54.320,0:11:58.240 +the links on the side you can see that + +0:11:55.920,0:12:00.480 +exactly the same we have a link + +0:11:58.240,0:12:02.639 +now just to make the pictures complete + +0:12:00.480,0:12:05.200 +inside the file bar i'm going to insert + +0:12:02.639,0:12:06.959 +a link to foo i'm going to save i'm + +0:12:05.200,0:12:07.920 +going to go to the file foo and now on + +0:12:06.959,0:12:11.120 +the right side + +0:12:07.920,0:12:13.839 +you can see that we have two backlinks + +0:12:11.120,0:12:14.720 +now you're gonna tell me yeah thank you + +0:12:13.839,0:12:17.760 +leo but + +0:12:14.720,0:12:20.320 +what's the point well the thing is + +0:12:17.760,0:12:22.160 +it might sound it might seem very simple + +0:12:20.320,0:12:24.160 +but i've just shown you + +0:12:22.160,0:12:26.160 +but programmatically it's a little hard + +0:12:24.160,0:12:28.000 +to do like we have to + +0:12:26.160,0:12:30.079 +look into your files to make sure that + +0:12:28.000,0:12:32.240 +every time you link your file + +0:12:30.079,0:12:34.079 +somewhere else we need to track + +0:12:32.240,0:12:37.920 +everything down + +0:12:34.079,0:12:39.519 +and now as simple as orgrum might be + +0:12:37.920,0:12:42.240 +looking to you + +0:12:39.519,0:12:43.279 +the thing is what we try to do with + +0:12:42.240,0:12:45.920 +orgrum + +0:12:43.279,0:12:46.399 +is to make sure that your collection of + +0:12:45.920,0:12:50.320 +notes + +0:12:46.399,0:12:54.079 +remains consistent whatever we do + +0:12:50.320,0:12:56.880 +an example for instance like right now + +0:12:54.079,0:12:58.000 +i've told you about a file named foo and + +0:12:56.880,0:13:01.120 +the file name + +0:12:58.000,0:13:03.920 +bar let's say that for whatever reason + +0:13:01.120,0:13:04.720 +you decide to rename your file foo to + +0:13:03.920,0:13:08.079 +something + +0:13:04.720,0:13:11.040 +very original let's just say bar + +0:13:08.079,0:13:12.320 +so we actually have a way in emacs in + +0:13:11.040,0:13:14.560 +orgrim i should say + +0:13:12.320,0:13:15.680 +when you modify the title at the top of + +0:13:14.560,0:13:18.880 +the file + +0:13:15.680,0:13:20.320 +so we get foo i've modified it with baz + +0:13:18.880,0:13:22.000 +you can see at the bottom that right now + +0:13:20.320,0:13:22.519 +we haven't saved and we are still in the + +0:13:22.000,0:13:26.079 +file + +0:13:22.519,0:13:29.360 +fu.org i'm going to save + +0:13:26.079,0:13:32.560 +and now what you see is + +0:13:29.360,0:13:35.360 +a new name for the file but you may ask + +0:13:32.560,0:13:36.880 +wait a second in the other file we had a + +0:13:35.360,0:13:38.880 +link to this file + +0:13:36.880,0:13:40.560 +does it mean that it's broken does it + +0:13:38.880,0:13:43.440 +means does it mean sorry + +0:13:40.560,0:13:43.920 +that we cannot access the file anymore + +0:13:43.440,0:13:46.959 +but + +0:13:43.920,0:13:48.000 +when we go there beginning to go in the + +0:13:46.959,0:13:50.399 +index + +0:13:48.000,0:13:52.079 +so obviously the actual description of + +0:13:50.399,0:13:54.320 +the link hasn't been updated + +0:13:52.079,0:13:55.680 +but if i show you what goes on under the + +0:13:54.320,0:13:57.440 +hood by showing you + +0:13:55.680,0:14:00.000 +what is fontify what is behind the + +0:13:57.440,0:14:02.320 +content of the link + +0:14:00.000,0:14:04.079 +actually it didn't work and that's why + +0:14:02.320,0:14:04.639 +you never present live folks because + +0:14:04.079,0:14:05.920 +otherwise you're + +0:14:04.639,0:14:08.880 +just going to show problems with the + +0:14:05.920,0:14:12.079 +software and that's not good + +0:14:08.880,0:14:15.120 +so something must have gone on obviously + +0:14:12.079,0:14:17.120 +but generally speaking the file should + +0:14:15.120,0:14:18.959 +have been updated + +0:14:17.120,0:14:21.279 +damn i'm showing you bugging my software + +0:14:18.959,0:14:25.040 +that's not very professional now is it + +0:14:21.279,0:14:28.079 +basically to come back to the main id + +0:14:25.040,0:14:28.880 +what we try to do with orgrom is to make + +0:14:28.079,0:14:32.639 +sure that + +0:14:28.880,0:14:35.279 +everything remains consistent we + +0:14:32.639,0:14:37.360 +really much love the system of + +0:14:35.279,0:14:38.720 +organization that is behind this little + +0:14:37.360,0:14:40.240 +castle method + +0:14:38.720,0:14:41.600 +now i was going at this point of the + +0:14:40.240,0:14:42.639 +presentation basically i wanted to go + +0:14:41.600,0:14:45.199 +back to firefox + +0:14:42.639,0:14:46.880 +and show you more stuff but it's likely + +0:14:45.199,0:14:48.959 +that it's going to crash again + +0:14:46.880,0:14:50.240 +so i'm not going to tempt the devil and + +0:14:48.959,0:14:51.680 +i'm just going to continue talking to + +0:14:50.240,0:14:54.800 +you like that + +0:14:51.680,0:14:58.160 +so the zettelkasten method + +0:14:54.800,0:15:01.839 +is a very organic way + +0:14:58.160,0:15:04.959 +to write notes and if you think + +0:15:01.839,0:15:06.639 +i i believe as all mode users + +0:15:04.959,0:15:08.000 +we share quite a lot of features and i'm + +0:15:06.639,0:15:09.600 +out of time i'm just going to take one + +0:15:08.000,0:15:12.320 +more minute to answer this question + +0:15:09.600,0:15:14.560 +that i'm asking myself anyway but if + +0:15:12.320,0:15:16.079 +you're anything like me + +0:15:14.560,0:15:18.240 +you've you've been through many + +0:15:16.079,0:15:18.959 +iterations of your workflow inside of + +0:15:18.240,0:15:20.959 +mode + +0:15:18.959,0:15:22.959 +do i keep all my professional stuff + +0:15:20.959,0:15:24.399 +under one heading or do i create a + +0:15:22.959,0:15:25.920 +separate file for this + +0:15:24.399,0:15:28.000 +you know those types of questions on + +0:15:25.920,0:15:30.639 +which you could ponder for + +0:15:28.000,0:15:31.360 +many many hours at night generally when + +0:15:30.639,0:15:34.560 +you have a + +0:15:31.360,0:15:36.959 +tight deadline to be following but + +0:15:34.560,0:15:38.240 +what i've discovered by using orgrim for + +0:15:36.959,0:15:40.720 +taking notes about + +0:15:38.240,0:15:41.360 +my academic projects or by taking notes + +0:15:40.720,0:15:44.880 +on + +0:15:41.360,0:15:47.440 +you know anything worth writing about + +0:15:44.880,0:15:49.199 +is that not having to worry about the + +0:15:47.440,0:15:52.399 +structure if you files + +0:15:49.199,0:15:56.079 +just having to worry about atoms + +0:15:52.399,0:15:58.480 +and links it does wonder + +0:15:56.079,0:16:00.639 +for the way you think about problems it + +0:15:58.480,0:16:04.800 +does wonder about your creativity + +0:16:00.639,0:16:07.519 +and it does wonder about your ability to + +0:16:04.800,0:16:08.800 +take your thoughts put them on a paper + +0:16:07.519,0:16:10.399 +and generally you know during this + +0:16:08.800,0:16:13.120 +process you realize oh maybe i do not + +0:16:10.399,0:16:16.079 +know this concept as well as i should + +0:16:13.120,0:16:16.800 +but i've never had a system which + +0:16:16.079,0:16:19.839 +brought me + +0:16:16.800,0:16:21.440 +as much serendipity as this system + +0:16:19.839,0:16:24.880 +and for those who don't know serendipity + +0:16:21.440,0:16:28.800 +the ability to come up with novel ideas + +0:16:24.880,0:16:32.240 +on the spot contextually so + +0:16:28.800,0:16:34.959 +this was just a little primer on what + +0:16:32.240,0:16:36.000 +orgrom and the zettelkasten is about in + +0:16:34.959,0:16:38.000 +about + +0:16:36.000,0:16:39.680 +20 minutes i'll be giving you a talk + +0:16:38.000,0:16:40.800 +about the technical aspects of orgrim + +0:16:39.680,0:16:43.040 +which i'm certain + +0:16:40.800,0:16:44.160 +some of you will be very interested in + +0:16:43.040,0:16:46.160 +and + +0:16:44.160,0:16:48.560 +otherwise i do have a youtube channel + +0:16:46.160,0:16:50.720 +where i try to + +0:16:48.560,0:16:52.079 +record videos where i explain to you + +0:16:50.720,0:16:53.839 +what the org + +0:16:52.079,0:16:55.600 +what organ is about what the method is + +0:16:53.839,0:16:57.040 +about and + +0:16:55.600,0:16:58.720 +and i'll just finish on this i'm two + +0:16:57.040,0:17:02.399 +minutes extra time sorry + +0:16:58.720,0:17:04.079 +but um we do know that a lot of people + +0:17:02.399,0:17:04.959 +are interested into orgrim i mentioned + +0:17:04.079,0:17:06.160 +at the very beginning of the + +0:17:04.959,0:17:09.360 +presentation + +0:17:06.160,0:17:10.640 +that a lot of people discovered emacs + +0:17:09.360,0:17:14.640 +and orgrom + +0:17:10.640,0:17:18.400 +and old mode even through orgrom + +0:17:14.640,0:17:20.959 +and we feel that we have a duty to + +0:17:18.400,0:17:22.720 +introduce those people this new pool of + +0:17:20.959,0:17:25.439 +people most of whom are + +0:17:22.720,0:17:27.600 +academics into the world of emacs and + +0:17:25.439,0:17:30.240 +into the water free software + +0:17:27.600,0:17:32.240 +and right now the thing is we're not + +0:17:30.240,0:17:34.080 +doing a particularly good job at writing + +0:17:32.240,0:17:36.160 +manuals i'm just going to try + +0:17:34.080,0:17:37.360 +to stop sharing my screen because i'm + +0:17:36.160,0:17:40.240 +nearly to the end + +0:17:37.360,0:17:41.919 +and just try sharing my firefox windows + +0:17:40.240,0:17:43.120 +if it allows me no it doesn't allow me + +0:17:41.919,0:17:44.160 +which is very good that's why i won't + +0:17:43.120,0:17:47.200 +have to + +0:17:44.160,0:17:50.080 +to screw things up but + +0:17:47.200,0:17:50.880 +uh we know that our manual is not fully + +0:17:50.080,0:17:53.760 +up to date + +0:17:50.880,0:17:54.480 +but believe me one of the key focus + +0:17:53.760,0:17:56.960 +right now + +0:17:54.480,0:17:57.840 +is making sure that within two to three + +0:17:56.960,0:17:59.679 +months + +0:17:57.840,0:18:02.559 +we have a good tutorial for people to + +0:17:59.679,0:18:03.840 +join and we have good videos for people + +0:18:02.559,0:18:04.640 +to get introduced to the topics we're + +0:18:03.840,0:18:06.320 +covering + +0:18:04.640,0:18:07.679 +and that's me done so thank you so much + +0:18:06.320,0:18:09.840 +for listening and now i'll be taking + +0:18:07.679,0:18:12.880 +some questions + +0:18:09.840,0:18:17.679 +thank you very much leo oh thank you + +0:18:12.880,0:18:19.440 +cheers we have i think about two minutes + +0:18:17.679,0:18:20.880 +four questions and i see a lot of them + +0:18:19.440,0:18:23.120 +on the pad + +0:18:20.880,0:18:24.320 +would you take them sure so yep i'm + +0:18:23.120,0:18:27.600 +scrolling i'm scrolling + +0:18:24.320,0:18:30.000 +uh getting things done that's aldrich uh + +0:18:27.600,0:18:31.679 +still scrolling okay olgram oh wow okay + +0:18:30.000,0:18:33.600 +so we do have quite a lot of questions + +0:18:31.679,0:18:34.799 +so please excuse me if i'm answering + +0:18:33.600,0:18:35.760 +your questions really fast but i just + +0:18:34.799,0:18:38.080 +want to make sure that i cover + +0:18:35.760,0:18:40.240 +as much ground as possible so what is + +0:18:38.080,0:18:41.039 +the functionality of all chrome unlinked + +0:18:40.240,0:18:43.200 +references + +0:18:41.039,0:18:45.200 +so basically when you have a file that + +0:18:43.200,0:18:48.000 +is not linked anywhere + +0:18:45.200,0:18:49.520 +this function allows you to see uh let's + +0:18:48.000,0:18:51.200 +say we have a file emacs + +0:18:49.520,0:18:53.200 +and we've talked about emacs in another + +0:18:51.200,0:18:57.440 +note but we haven't created a link + +0:18:53.200,0:18:59.520 +what this command do is that it + +0:18:57.440,0:19:00.720 +looks into your folder for every mention + +0:18:59.520,0:19:03.840 +of emacs that is not + +0:19:00.720,0:19:05.039 +linked to the note emacs and it prints + +0:19:03.840,0:19:06.480 +all the results in the buffer so that + +0:19:05.039,0:19:07.840 +you know okay i've talked about emacs + +0:19:06.480,0:19:10.480 +here but i didn't create a link + +0:19:07.840,0:19:11.840 +do i want to create a link that's it so + +0:19:10.480,0:19:12.480 +is it possible to use the backlinks + +0:19:11.840,0:19:15.039 +features + +0:19:12.480,0:19:16.400 +in regular old buffers right now no it + +0:19:15.039,0:19:18.080 +is not possible we are + +0:19:16.400,0:19:20.240 +having a very controlled environment + +0:19:18.080,0:19:21.280 +which is i told you about this clipbox + +0:19:20.240,0:19:22.799 +folder before + +0:19:21.280,0:19:24.400 +this is where we keep all the nodes and + +0:19:22.799,0:19:26.080 +the reason why we do this will be more + +0:19:24.400,0:19:27.360 +evident when i go through the technical + +0:19:26.080,0:19:30.720 +presentation + +0:19:27.360,0:19:32.080 +but uh it's because of optimization + +0:19:30.720,0:19:33.760 +so i'll get back to you on that + +0:19:32.080,0:19:35.440 +afterwards um + +0:19:33.760,0:19:37.039 +do you make all group database + +0:19:35.440,0:19:39.760 +accessible across computers + +0:19:37.039,0:19:41.760 +uh no i do not because i'm only using my + +0:19:39.760,0:19:44.559 +laptop but plenty of people have had + +0:19:41.760,0:19:47.039 +a lot of success doing so either by + +0:19:44.559,0:19:47.679 +sharing the files via a sync thing or by + +0:19:47.039,0:19:49.760 +any other + +0:19:47.679,0:19:52.400 +method we have a section in a manual + +0:19:49.760,0:19:53.760 +specifying how to do this uh how do you + +0:19:52.400,0:19:54.880 +discover the tags links to add to your + +0:19:53.760,0:19:56.160 +new algorithm note + +0:19:54.880,0:19:57.679 +there is something that i didn't tell + +0:19:56.160,0:19:58.240 +you about which is called orgrim server + +0:19:57.679,0:20:01.679 +which is a + +0:19:58.240,0:20:04.320 +magnificent way to uh access + +0:20:01.679,0:20:05.360 +visually the nodes that you have in your + +0:20:04.320,0:20:07.840 +in your system + +0:20:05.360,0:20:08.799 +you'll have to go to the orgrom.com + +0:20:07.840,0:20:10.640 +website + +0:20:08.799,0:20:12.080 +and please go on our github page and we + +0:20:10.640,0:20:14.640 +show everything and + +0:20:12.080,0:20:16.000 +um i hope what i've told you has excited + +0:20:14.640,0:20:18.000 +you so please go + +0:20:16.000,0:20:20.080 +uh maybe one more question two more + +0:20:18.000,0:20:21.679 +questions just to make sure uh is it + +0:20:20.080,0:20:23.039 +possible to seamlessly link to other + +0:20:21.679,0:20:23.919 +notes with syntax instead of a + +0:20:23.039,0:20:25.840 +keybinding + +0:20:23.919,0:20:27.120 +yes we are working on this this is a + +0:20:25.840,0:20:28.880 +huge project that we're doing with + +0:20:27.120,0:20:30.960 +orgrim which is called uh + +0:20:28.880,0:20:32.880 +link ux and we're trying to do something + +0:20:30.960,0:20:34.559 +which is very close to rome research + +0:20:32.880,0:20:36.880 +which is the software we're using for + +0:20:34.559,0:20:39.200 +inspiration for orgrom + +0:20:36.880,0:20:41.280 +and uh yes there's there are going to be + +0:20:39.200,0:20:42.640 +ways to do this in the future i'm going + +0:20:41.280,0:20:45.280 +to give you a window of + +0:20:42.640,0:20:46.320 +maybe three to four months and one last + +0:20:45.280,0:20:48.480 +question + +0:20:46.320,0:20:49.440 +uh good on you thank you well thank you + +0:20:48.480,0:20:51.039 +for for this + +0:20:49.440,0:20:53.200 +is there an easy way to export several + +0:20:51.039,0:20:56.960 +selected nodes to say a lattice file + +0:20:53.200,0:20:59.840 +latex yes uh i mean it's old mode + +0:20:56.960,0:21:00.480 +at the very core it is org mode so you + +0:20:59.840,0:21:02.559 +know you don't + +0:21:00.480,0:21:04.000 +if you want to export to latex file you + +0:21:02.559,0:21:06.320 +can you just use the + +0:21:04.000,0:21:08.320 +aux latex library which you can access + +0:21:06.320,0:21:11.760 +by pressing ctrl c ctrl + +0:21:08.320,0:21:12.480 +e for export all right is it uh i + +0:21:11.760,0:21:13.919 +believe i'm + +0:21:12.480,0:21:16.880 +it's all the time i had i mean can you + +0:21:13.919,0:21:19.039 +confirm this + +0:21:16.880,0:21:20.240 +okay so if you have more questions don't +

has talked about like the overall + +0:00:10.559,0:00:15.120 +picture of orgrim and or + +0:00:12.639,0:00:16.240 +uh bibtex or groundbreak tech i will be + +0:00:15.120,0:00:19.199 +talking more about + +0:00:16.240,0:00:20.320 +the research process itself using these + +0:00:19.199,0:00:22.400 +tools + +0:00:20.320,0:00:25.039 +all right so just to introduce that the + +0:00:22.400,0:00:28.080 +research process is really messy + +0:00:25.039,0:00:31.039 +um you're always working in like + +0:00:28.080,0:00:32.960 +piecemeal tasks and things move around + +0:00:31.039,0:00:35.280 +all the time and so + +0:00:32.960,0:00:36.880 +there needs to be a system where you can + +0:00:35.280,0:00:39.360 +organize all these tasks + +0:00:36.880,0:00:41.760 +all these ideas in a way that is + +0:00:39.360,0:00:44.239 +flexible and effective + +0:00:41.760,0:00:44.960 +so my motivation is that research is + +0:00:44.239,0:00:47.120 +hard and + +0:00:44.960,0:00:49.600 +writing about it is even more difficult + +0:00:47.120,0:00:51.120 +and my goal is to add some structure to + +0:00:49.600,0:00:52.800 +this whole madness + +0:00:51.120,0:00:54.480 +so here's a list of some of the stuff + +0:00:52.800,0:00:57.199 +that i've been using since i first + +0:00:54.480,0:01:00.160 +learned about emacs in 2019 + +0:00:57.199,0:01:02.000 +and what i've what i've found useful um + +0:01:00.160,0:01:05.199 +during my res uh like um + +0:01:02.000,0:01:07.920 +within my research process all right so + +0:01:05.199,0:01:10.400 +i've organized org mode for researchers + +0:01:07.920,0:01:12.400 +and scholars within the writing process + +0:01:10.400,0:01:14.320 +into three modules first there's like + +0:01:12.400,0:01:15.759 +the planning aspect of it + +0:01:14.320,0:01:17.680 +then you've got the writing and the + +0:01:15.759,0:01:18.320 +reference management which i will join + +0:01:17.680,0:01:20.560 +together + +0:01:18.320,0:01:21.920 +by looking at the example of doing your + +0:01:20.560,0:01:24.720 +literature review + +0:01:21.920,0:01:26.479 +all right so when we're talking about + +0:01:24.720,0:01:27.360 +planning we're talking about either task + +0:01:26.479,0:01:30.880 +management or + +0:01:27.360,0:01:31.600 +time management with task management + +0:01:30.880,0:01:33.840 +you've got + +0:01:31.600,0:01:36.159 +org modes to do's and tags and + +0:01:33.840,0:01:38.479 +categories these are really powerful + +0:01:36.159,0:01:41.600 +tools that you could use + +0:01:38.479,0:01:44.799 +um in your org files to just um + +0:01:41.600,0:01:47.040 +uh like organize your tasks and + +0:01:44.799,0:01:49.040 +your appointments so there are different + +0:01:47.040,0:01:50.960 +types of to-do's that you can either set + +0:01:49.040,0:01:52.799 +globally in your init file or they can + +0:01:50.960,0:01:55.200 +be file buffer specific + +0:01:52.799,0:01:56.079 +so that means based on context based on + +0:01:55.200,0:01:57.759 +the type of + +0:01:56.079,0:01:59.280 +manuscript you're working on whether + +0:01:57.759,0:02:02.240 +it's like a literate programming + +0:01:59.280,0:02:03.759 +report or your actual thesis slash + +0:02:02.240,0:02:05.840 +dissertation + +0:02:03.759,0:02:07.759 +um also these to-do's are either created + +0:02:05.840,0:02:11.440 +as a set tree like think of them as + +0:02:07.759,0:02:14.800 +headings and sections if you use latex + +0:02:11.440,0:02:15.360 +or inline text which are like org inline + +0:02:14.800,0:02:17.760 +tasks i + +0:02:15.360,0:02:19.120 +like organ line tasks because like i can + +0:02:17.760,0:02:21.520 +add + +0:02:19.120,0:02:22.879 +to do's between two paragraphs and that + +0:02:21.520,0:02:25.360 +way it doesn't show up + +0:02:22.879,0:02:27.280 +in the table of contents when i export + +0:02:25.360,0:02:30.879 +into pdf or html or + +0:02:27.280,0:02:34.319 +anything else all right so this is an + +0:02:30.879,0:02:37.360 +example of buffer specific to do's + +0:02:34.319,0:02:39.120 +and and this is example of like a little + +0:02:37.360,0:02:40.800 +programming report that i was working on + +0:02:39.120,0:02:43.200 +where i was like dealing with + +0:02:40.800,0:02:44.080 +data and like analysis and all of that + +0:02:43.200,0:02:47.519 +stuff and so + +0:02:44.080,0:02:49.440 +i needed um context specific to do's to + +0:02:47.519,0:02:52.080 +use them within this buffer + +0:02:49.440,0:02:54.319 +um and that's how i would organize it + +0:02:52.080,0:02:57.200 +and there's also also another example + +0:02:54.319,0:02:57.920 +of an org inline task where you could + +0:02:57.200,0:03:01.360 +see it + +0:02:57.920,0:03:03.040 +in the middle between the two headings + +0:03:01.360,0:03:04.959 +that way it wouldn't show up in the + +0:03:03.040,0:03:06.480 +table of contents and it would look like + +0:03:04.959,0:03:09.519 +nature within the + +0:03:06.480,0:03:11.920 +text when you export it + +0:03:09.519,0:03:13.280 +oh but i also added a tag of no export + +0:03:11.920,0:03:16.400 +so it won't show up at all + +0:03:13.280,0:03:19.360 +when i export it into like either pdf + +0:03:16.400,0:03:21.599 +which i use all the time all right so + +0:03:19.360,0:03:24.159 +another useful tool + +0:03:21.599,0:03:25.200 +um for the research and just like + +0:03:24.159,0:03:27.920 +general planning + +0:03:25.200,0:03:29.120 +is the org capture um when i first + +0:03:27.920,0:03:32.080 +started with emacs + +0:03:29.120,0:03:34.239 +actually it was for org agenda and i + +0:03:32.080,0:03:35.360 +went crazy with my capture template i + +0:03:34.239,0:03:37.599 +created a template for + +0:03:35.360,0:03:38.640 +everything um because i was just so + +0:03:37.599,0:03:40.720 +excited + +0:03:38.640,0:03:42.400 +but with time i was using less and less + +0:03:40.720,0:03:46.319 +of them so i kept taking them out + +0:03:42.400,0:03:48.239 +and now this is my simplified um + +0:03:46.319,0:03:49.599 +capture templates that i use either for + +0:03:48.239,0:03:52.159 +a general to do + +0:03:49.599,0:03:54.159 +um for a regular appointment a fleeting + +0:03:52.159,0:03:55.200 +note research tasks because like those + +0:03:54.159,0:03:56.959 +are what i focus on + +0:03:55.200,0:03:58.720 +like my bread and butter and then + +0:03:56.959,0:04:00.879 +finally with meetings which i find + +0:03:58.720,0:04:01.680 +sometimes i don't use it as much because + +0:04:00.879,0:04:03.519 +i would just like + +0:04:01.680,0:04:04.879 +have the org file ready instead of + +0:04:03.519,0:04:07.920 +needing to capture + +0:04:04.879,0:04:11.439 +you know open a capture template + +0:04:07.920,0:04:12.400 +right or agenda um that's how i got into + +0:04:11.439,0:04:15.439 +emacs + +0:04:12.400,0:04:16.799 +i needed to um organize my life and i + +0:04:15.439,0:04:19.199 +found emacs and + +0:04:16.799,0:04:20.479 +it's been great ever since um it + +0:04:19.199,0:04:22.720 +populates all your to-do's and + +0:04:20.479,0:04:25.280 +appointments into a singular view so the + +0:04:22.720,0:04:29.120 +default view i think it's a weak view + +0:04:25.280,0:04:31.919 +however i use org super agenda love this + +0:04:29.120,0:04:34.160 +um package and i set up my agenda as a + +0:04:31.919,0:04:37.360 +daily view with just appointments + +0:04:34.160,0:04:38.720 +deadlines and a habit tracker um and + +0:04:37.360,0:04:40.639 +a side note you guys i'm still + +0:04:38.720,0:04:42.320 +struggling with organizing the perfect + +0:04:40.639,0:04:45.360 +agenda so it's a process + +0:04:42.320,0:04:47.919 +and take it easy all right + +0:04:45.360,0:04:50.320 +so this is just an overview of my daily + +0:04:47.919,0:04:52.800 +agenda as you can see they're just like + +0:04:50.320,0:04:55.520 +appointments that i import from gmail + +0:04:52.800,0:04:57.919 +using org gcal + +0:04:55.520,0:04:58.880 +a simple habit tracker of like daily + +0:04:57.919,0:05:00.960 +free writing + +0:04:58.880,0:05:02.800 +as you can see there are a lot of times + +0:05:00.960,0:05:05.199 +where i'm skipping and the asterisk is + +0:05:02.800,0:05:08.479 +the one where i've completed that day + +0:05:05.199,0:05:10.080 +so you know it's a process and then just + +0:05:08.479,0:05:12.639 +like regular deadlines + +0:05:10.080,0:05:14.000 +so what happens is that i have other + +0:05:12.639,0:05:17.120 +to-do's that i have + +0:05:14.000,0:05:17.919 +not scheduled or not added a deadline + +0:05:17.120,0:05:20.560 +but they're just + +0:05:17.919,0:05:22.320 +tasks that keep piling up when i first + +0:05:20.560,0:05:24.880 +started with emacs and org agenda + +0:05:22.320,0:05:26.880 +i had everything in there and it got + +0:05:24.880,0:05:29.680 +overwhelming and then i decided no + +0:05:26.880,0:05:30.800 +i'm not gonna even let them show up so + +0:05:29.680,0:05:33.120 +what i would do + +0:05:30.800,0:05:34.479 +at the beginning of each week or the + +0:05:33.120,0:05:36.800 +night before + +0:05:34.479,0:05:38.000 +um i would sit down look at all my to + +0:05:36.800,0:05:40.720 +to-do's that i have + +0:05:38.000,0:05:42.639 +not assigned yet to a deadline or a + +0:05:40.720,0:05:45.360 +schedule or just a simple + +0:05:42.639,0:05:46.320 +timestamp um and i would organize them + +0:05:45.360,0:05:49.520 +throughout the week + +0:05:46.320,0:05:51.680 +so here's an example of what i did + +0:05:49.520,0:05:53.039 +so on that wednesday from my gmail i had + +0:05:51.680,0:05:55.600 +all these appointments but + +0:05:53.039,0:05:56.560 +one of them is i have a writing group + +0:05:55.600,0:05:58.400 +session + +0:05:56.560,0:05:59.759 +and so i looked at my tasks and i + +0:05:58.400,0:06:02.639 +thought okay then i will just + +0:05:59.759,0:06:03.520 +assign um like for example my emac + +0:06:02.639,0:06:06.319 +slides + +0:06:03.520,0:06:07.280 +or the framework diagram into that + +0:06:06.319,0:06:09.600 +writing session + +0:06:07.280,0:06:10.800 +and all i did was just add an active + +0:06:09.600,0:06:12.960 +timestamp + +0:06:10.800,0:06:14.000 +that is all i needed to do and it went + +0:06:12.960,0:06:17.120 +straight into my + +0:06:14.000,0:06:20.080 +appointment now if i miss that + +0:06:17.120,0:06:21.520 +it won't show up on the next day so if + +0:06:20.080,0:06:24.639 +you put in a deadline + +0:06:21.520,0:06:26.560 +it will show up as an overdue but if you + +0:06:24.639,0:06:29.280 +have no deadline or schedule it will not + +0:06:26.560,0:06:32.960 +show up in your daily org agenda + +0:06:29.280,0:06:35.680 +so just a star + +0:06:32.960,0:06:37.520 +all right another way of accessing your + +0:06:35.680,0:06:40.880 +to do's is that if it's + +0:06:37.520,0:06:42.160 +um file specific org file specific + +0:06:40.880,0:06:44.160 +buffer specific + +0:06:42.160,0:06:46.400 +and so like when we talked about like + +0:06:44.160,0:06:47.680 +whether to have a big ass org file or + +0:06:46.400,0:06:50.720 +like tiny files + +0:06:47.680,0:06:54.560 +it all depends and this isn't the the + +0:06:50.720,0:06:55.759 +um you know the way this depends + +0:06:54.560,0:06:58.400 +because if you're working on like a + +0:06:55.759,0:06:59.680 +dissertation um it's a huge manuscript + +0:06:58.400,0:07:02.880 +you need to like work + +0:06:59.680,0:07:05.759 +on that org file all the time um + +0:07:02.880,0:07:07.680 +then yes it might do should be in that + +0:07:05.759,0:07:08.000 +file specifically because every time if + +0:07:07.680,0:07:09.680 +i'm + +0:07:08.000,0:07:12.479 +if i'm visiting this org file all the + +0:07:09.680,0:07:15.520 +time i should be able to just look at my + +0:07:12.479,0:07:18.639 +tasks from uh within that buffer + +0:07:15.520,0:07:21.599 +and so i use org sidebar to + +0:07:18.639,0:07:22.960 +keep all these specific uh to do's + +0:07:21.599,0:07:26.560 +within that org file + +0:07:22.960,0:07:28.400 +i find it helpful okay + +0:07:26.560,0:07:29.759 +now that we're going into the writing + +0:07:28.400,0:07:33.039 +and reference management + +0:07:29.759,0:07:35.840 +we'll call it a literature review um + +0:07:33.039,0:07:36.639 +and this is something i've built as a + +0:07:35.840,0:07:40.240 +schema + +0:07:36.639,0:07:43.759 +i think that it works for now + +0:07:40.240,0:07:45.919 +um and it requires one outside pack + +0:07:43.759,0:07:47.680 +of outside software which is zotero what + +0:07:45.919,0:07:48.720 +i use it's an open source reference + +0:07:47.680,0:07:51.759 +management + +0:07:48.720,0:07:53.599 +software um it's great + +0:07:51.759,0:07:55.120 +but the things to keep in mind is that i + +0:07:53.599,0:07:58.319 +use two um + +0:07:55.120,0:08:01.039 +plugins that is really needed for when + +0:07:58.319,0:08:03.840 +we work with orgrim bibtex and orgrim + +0:08:01.039,0:08:06.160 +and org mode um and the zap file so + +0:08:03.840,0:08:07.039 +better bibtex organizes your reference + +0:08:06.160,0:08:10.560 +keys + +0:08:07.039,0:08:13.360 +um in um in a way like in a fashion that + +0:08:10.560,0:08:14.240 +works for you so for me all my reference + +0:08:13.360,0:08:17.280 +keys are like + +0:08:14.240,0:08:21.120 +last author and gear um and with zap + +0:08:17.280,0:08:22.319 +file i um i let it like rename all the + +0:08:21.120,0:08:24.400 +pdf files + +0:08:22.319,0:08:26.000 +the same way that i have for my bit of + +0:08:24.400,0:08:29.360 +my bib keys which is like + +0:08:26.000,0:08:33.440 +last name of author and year all right + +0:08:29.360,0:08:37.120 +once you export your entire + +0:08:33.440,0:08:39.440 +library as a bib file then you can work + +0:08:37.120,0:08:42.880 +on it within org mode and emacs + +0:08:39.440,0:08:45.040 +using um the following packages + +0:08:42.880,0:08:47.839 +all right so with orgrim bibtex it + +0:08:45.040,0:08:49.519 +creates an org file for each bib entry + +0:08:47.839,0:08:52.240 +and you have the option of like + +0:08:49.519,0:08:54.880 +templating and doing other stuff with it + +0:08:52.240,0:08:56.240 +and then finally there's like this orb + +0:08:54.880,0:08:58.800 +pdf scraper + +0:08:56.240,0:09:00.240 +i've used it briefly but i think the + +0:08:58.800,0:09:02.880 +potential + +0:09:00.240,0:09:05.920 +with or pdf scraper is if you're gonna + +0:09:02.880,0:09:08.320 +do a bibliometric study or like a + +0:09:05.920,0:09:10.000 +systematic literature view there's + +0:09:08.320,0:09:10.959 +something there but i have to look + +0:09:10.000,0:09:14.399 +through it + +0:09:10.959,0:09:16.880 +anyway so once you create your you know + +0:09:14.399,0:09:18.160 +your reference file of reference x and + +0:09:16.880,0:09:20.240 +you're writing your notes + +0:09:18.160,0:09:22.399 +you can either go like with going + +0:09:20.240,0:09:24.080 +through org mode you're writing + +0:09:22.399,0:09:26.080 +your ideas you're writing your notes + +0:09:24.080,0:09:27.839 +you're assigning tasks + +0:09:26.080,0:09:30.480 +and then there's org transclusion which + +0:09:27.839,0:09:32.240 +i will mention briefly at the end + +0:09:30.480,0:09:35.360 +and ways to extract if you're going to + +0:09:32.240,0:09:36.640 +go through the orgrom + +0:09:35.360,0:09:38.720 +things that you're going to use within + +0:09:36.640,0:09:40.000 +orgrom it's a great way to build your + +0:09:38.720,0:09:42.880 +database you start making the + +0:09:40.000,0:09:44.959 +connections and you can visualize your + +0:09:42.880,0:09:46.240 +notes and like how these references are + +0:09:44.959,0:09:48.839 +linked to each other + +0:09:46.240,0:09:50.240 +through the organ server or or ground + +0:09:48.839,0:09:53.120 +graph + +0:09:50.240,0:09:53.680 +all right this is just notes for later + +0:09:53.120,0:09:56.240 +okay + +0:09:53.680,0:09:57.360 +so this is an example of like an orgram + +0:09:56.240,0:09:59.279 +file that i have + +0:09:57.360,0:10:01.760 +for example if i'm working on adaptation + +0:09:59.279,0:10:02.560 +policy i have these hyperlinks that are + +0:10:01.760,0:10:04.959 +linked to other + +0:10:02.560,0:10:06.640 +concepts and ideas such as either + +0:10:04.959,0:10:08.720 +climate security + +0:10:06.640,0:10:10.560 +um changing global environment so on and + +0:10:08.720,0:10:13.920 +so forth and the backlinks + +0:10:10.560,0:10:15.839 +are other references that talk about + +0:10:13.920,0:10:17.680 +this specific concept + +0:10:15.839,0:10:19.920 +so this is really helpful and then when + +0:10:17.680,0:10:22.160 +you visualize it the picture on the left + +0:10:19.920,0:10:24.160 +which i'm sure looks really small + +0:10:22.160,0:10:25.680 +um you can see the connections that it's + +0:10:24.160,0:10:28.160 +making with other + +0:10:25.680,0:10:29.760 +references so of course this is just + +0:10:28.160,0:10:32.720 +like a buffer + +0:10:29.760,0:10:34.560 +network when you look at the entire + +0:10:32.720,0:10:38.000 +database network it's it's + +0:10:34.560,0:10:41.680 +it's growing okay + +0:10:38.000,0:10:44.079 +so going into organ bidtech + +0:10:41.680,0:10:46.000 +so it utilizes a combination of the or + +0:10:44.079,0:10:46.880 +graph package helmbik tech candidate + +0:10:46.000,0:10:50.079 +completion + +0:10:46.880,0:10:51.440 +and it works with orgrom functionalities + +0:10:50.079,0:10:54.880 +and + +0:10:51.440,0:10:57.440 +other good stuff this is an example + +0:10:54.880,0:10:58.720 +of my orgrim bibtex file all right so + +0:10:57.440,0:11:01.200 +i've created + +0:10:58.720,0:11:02.320 +um the template which i pretty much use + +0:11:01.200,0:11:05.920 +what leo + +0:11:02.320,0:11:08.640 +has uh produced like in his um + +0:11:05.920,0:11:10.160 +tutorial so i think it's it's great it + +0:11:08.640,0:11:12.880 +works well for me + +0:11:10.160,0:11:14.480 +um and what it does is that it works + +0:11:12.880,0:11:17.519 +with your bib file + +0:11:14.480,0:11:19.519 +so if you're in your bib file you have a + +0:11:17.519,0:11:21.040 +sub entry that's called keywords and + +0:11:19.519,0:11:23.120 +usually that's within + +0:11:21.040,0:11:24.560 +a journal article the author would + +0:11:23.120,0:11:27.519 +specify these + +0:11:24.560,0:11:28.160 +keywords um when it gets imported into + +0:11:27.519,0:11:30.399 +zotero + +0:11:28.160,0:11:32.399 +it extracts those keywords and then it + +0:11:30.399,0:11:34.959 +gets populated as an org file + +0:11:32.399,0:11:36.959 +with orgrim bibtex so i always start + +0:11:34.959,0:11:38.560 +with the meta information first and then + +0:11:36.959,0:11:42.480 +i would write my notes + +0:11:38.560,0:11:45.760 +after that this is an example though + +0:11:42.480,0:11:49.120 +for reference of a physical book so + +0:11:45.760,0:11:51.519 +i don't have a pdf file for it um + +0:11:49.120,0:11:53.920 +so what i've figured out like a new idea + +0:11:51.519,0:11:55.760 +for it so if i'm writing notes on it + +0:11:53.920,0:11:57.279 +i would create a property that says + +0:11:55.760,0:11:58.959 +pages um + +0:11:57.279,0:12:00.639 +that way it's easier for you when you go + +0:11:58.959,0:12:02.720 +back to citing + +0:12:00.639,0:12:04.720 +um certain ideas or something that you + +0:12:02.720,0:12:07.839 +have the pages prepared there + +0:12:04.720,0:12:11.279 +it's easier that way okay + +0:12:07.839,0:12:13.040 +org noter which is something i + +0:12:11.279,0:12:14.880 +use a lot especially with journal + +0:12:13.040,0:12:15.600 +articles that have pdfs and stuff like + +0:12:14.880,0:12:19.120 +that + +0:12:15.600,0:12:22.720 +they're really helpful if you are gonna + +0:12:19.120,0:12:23.760 +if you've just started using um emacs + +0:12:22.720,0:12:26.959 +and orgrim + +0:12:23.760,0:12:29.519 +and you have all these pdfs that have + +0:12:26.959,0:12:30.079 +all the annotations and highlighting and + +0:12:29.519,0:12:32.639 +the + +0:12:30.079,0:12:33.200 +all that stuff with org noter you can + +0:12:32.639,0:12:36.720 +just + +0:12:33.200,0:12:39.519 +use the org note or create skeleton + +0:12:36.720,0:12:41.200 +uh command and it will populate all your + +0:12:39.519,0:12:43.760 +notes that have already been + +0:12:41.200,0:12:44.800 +um entered within the pdf file if you're + +0:12:43.760,0:12:48.160 +using an outside + +0:12:44.800,0:12:52.560 +software and creates them like as a neat + +0:12:48.160,0:12:55.920 +org file i i highly recommend + +0:12:52.560,0:12:57.920 +finally org transclusion um + +0:12:55.920,0:13:01.040 +i think this is still in its beta phase + +0:12:57.920,0:13:02.720 +but i've been enjoying it so far + +0:13:01.040,0:13:04.800 +um i'm guessing people know what + +0:13:02.720,0:13:06.480 +translation mean which is sort of like + +0:13:04.800,0:13:09.600 +copy pasting text from + +0:13:06.480,0:13:11.839 +one org file to another this is helpful + +0:13:09.600,0:13:12.959 +i i think i i peeked at a question that + +0:13:11.839,0:13:16.320 +was talking about like + +0:13:12.959,0:13:18.320 +you know linking um to other org files + +0:13:16.320,0:13:20.320 +i think org transclusion could really + +0:13:18.320,0:13:24.399 +work okay it's + +0:13:20.320,0:13:27.760 +equivalent to the include + +0:13:24.399,0:13:29.519 +function within org mode um but i think + +0:13:27.760,0:13:32.560 +so like if you have other files + +0:13:29.519,0:13:34.800 +that you know which region that you + +0:13:32.560,0:13:36.079 +need in another file you could use the + +0:13:34.800,0:13:38.160 +include but with + +0:13:36.079,0:13:39.440 +org transclusion it's great i mean you + +0:13:38.160,0:13:42.720 +just have + +0:13:39.440,0:13:43.360 +um you're just linking one part to the + +0:13:42.720,0:13:45.760 +other + +0:13:43.360,0:13:47.760 +sort of like not refiling but you know + +0:13:45.760,0:13:49.680 +hyperlinking + +0:13:47.760,0:13:51.120 +so this is an example of what org + +0:13:49.680,0:13:53.680 +transclusion looks like + +0:13:51.120,0:13:54.720 +um so the highlighted problem statement + +0:13:53.680,0:13:57.760 +is from another + +0:13:54.720,0:13:58.240 +org file and then what i would do is + +0:13:57.760,0:13:59.760 +just like + +0:13:58.240,0:14:01.440 +link it to there and there was like a + +0:13:59.760,0:14:05.440 +transclusion command + +0:14:01.440,0:14:08.399 +i wish i made another screenshot of it + +0:14:05.440,0:14:09.120 +and so when you invoke org transclusion + +0:14:08.399,0:14:12.079 +mode + +0:14:09.120,0:14:12.480 +it turns um it prints it out like that + +0:14:12.079,0:14:15.120 +so + +0:14:12.480,0:14:16.560 +it's in view mode and then when you want + +0:14:15.120,0:14:18.480 +to edit it will take you back to that + +0:14:16.560,0:14:21.839 +buffer and you can edit the text + +0:14:18.480,0:14:22.720 +however you want all right so thank you + +0:14:21.839,0:14:26.000 +so much + +0:14:22.720,0:14:29.120 +um i wanted to leave room for questions + +0:14:26.000,0:14:32.560 +but special thanks to all the folks that + +0:14:29.120,0:14:33.440 +work on orgrom or ground bibtex orgrim + +0:14:32.560,0:14:36.320 +server or + +0:14:33.440,0:14:38.240 +transclusion and of course alpha papo on + +0:14:36.320,0:14:42.560 +or super agenda and org sidebar + +0:14:38.240,0:14:42.560 +that's how i got into emacs thank you + +0:14:43.440,0:14:47.120 +all right and uh well thank you so yeah + +0:14:45.600,0:14:49.120 +this time i'll be the one asking the + +0:14:47.120,0:14:51.360 +question and not i'm in so + +0:14:49.120,0:14:53.120 +i'm feeling filling big shoes right now + +0:14:51.360,0:14:54.880 +so you'll have to bear with me folks + +0:14:53.120,0:14:56.240 +so thank you so much noora for your + +0:14:54.880,0:14:57.279 +presentation that is incredibly + +0:14:56.240,0:14:58.959 +interesting + +0:14:57.279,0:15:00.800 +so would you mind if i fed you questions + +0:14:58.959,0:15:04.000 +from the charts yeah + +0:15:00.800,0:15:06.160 +go ahead okay so the first one i i've + +0:15:04.000,0:15:07.920 +picked on my end was did you try using + +0:15:06.160,0:15:10.560 +ebib instead of zotero + +0:15:07.920,0:15:12.079 +and if so is it better than zotero in + +0:15:10.560,0:15:14.880 +some ways + +0:15:12.079,0:15:15.680 +i no i have not used eb i've only used + +0:15:14.880,0:15:18.560 +mendeley + +0:15:15.680,0:15:20.320 +and then they got bought by el savior + +0:15:18.560,0:15:23.040 +and so like i was like okay i'm done + +0:15:20.320,0:15:25.120 +i'm going to zotero um there are a lot + +0:15:23.040,0:15:26.240 +of plugins with zotero that you can play + +0:15:25.120,0:15:28.320 +around with + +0:15:26.240,0:15:30.480 +so i can't speak for ebit but definitely + +0:15:28.320,0:15:32.079 +zotero it's been a good experience so + +0:15:30.480,0:15:34.880 +far + +0:15:32.079,0:15:35.360 +yes same i also i also do research on + +0:15:34.880,0:15:38.079 +the site + +0:15:35.360,0:15:39.360 +as i told you english major and yeah i + +0:15:38.079,0:15:41.839 +also do zotero + +0:15:39.360,0:15:43.759 +some people have been using uh a + +0:15:41.839,0:15:44.160 +connector between zotero and emacs which + +0:15:43.759,0:15:46.000 +has + +0:15:44.160,0:15:47.360 +they've had great success with them but + +0:15:46.000,0:15:50.480 +personally i haven't touched + +0:15:47.360,0:15:52.240 +touched it already so yeah + +0:15:50.480,0:15:53.920 +oh go ahead sorry all right so far i + +0:15:52.240,0:15:54.880 +don't have any problems with zotero but + +0:15:53.920,0:15:56.320 +maybe if i + +0:15:54.880,0:15:58.320 +run into something i might check out + +0:15:56.320,0:16:00.240 +ebay in the future + +0:15:58.320,0:16:01.680 +yeah definitely i think zotero is a very + +0:16:00.240,0:16:02.560 +solid project and you know the fact that + +0:16:01.680,0:16:04.959 +it's being used + +0:16:02.560,0:16:06.560 +by people outside of emacs also ensures + +0:16:04.959,0:16:07.680 +that there's quite a lot of packing + +0:16:06.560,0:16:09.759 +behind the software + +0:16:07.680,0:16:11.759 +which is reassuring when your livelihood + +0:16:09.759,0:16:13.519 +depends on your research + +0:16:11.759,0:16:15.600 +right and then i think one more thing + +0:16:13.519,0:16:17.519 +with zotero is that you can create + +0:16:15.600,0:16:18.079 +groups so if you're in a collaborative + +0:16:17.519,0:16:20.160 +project + +0:16:18.079,0:16:22.320 +you can create a reference you know a + +0:16:20.160,0:16:23.759 +library just for your group and i think + +0:16:22.320,0:16:25.279 +that could help because like i + +0:16:23.759,0:16:27.600 +i'm going to be in a project next + +0:16:25.279,0:16:29.839 +semester that requires that + +0:16:27.600,0:16:31.600 +yeah definitely i believe the ability to + +0:16:29.839,0:16:33.839 +have folders inside zotero + +0:16:31.600,0:16:35.360 +makes it incredibly useful to manage + +0:16:33.839,0:16:37.440 +your different projects concurrent + +0:16:35.360,0:16:39.279 +projects + +0:16:37.440,0:16:41.279 +so moving on to the questions do you + +0:16:39.279,0:16:43.440 +have any suggestion on what subjects or + +0:16:41.279,0:16:46.560 +things should be tags or separate organ + +0:16:43.440,0:16:50.320 +files for cross-linking + +0:16:46.560,0:16:52.720 +right um so so far now like i'm having + +0:16:50.320,0:16:55.360 +trouble with like should i be combining + +0:16:52.720,0:16:55.839 +certain concepts together as one like + +0:16:55.360,0:16:59.360 +this is + +0:16:55.839,0:17:00.959 +where the the thought process you know + +0:16:59.360,0:17:02.959 +starts coming to fruit is that when you + +0:17:00.959,0:17:04.880 +start you know combining + +0:17:02.959,0:17:06.480 +ideas together so you won't need a + +0:17:04.880,0:17:09.199 +specific tag + +0:17:06.480,0:17:11.280 +and another one that are like similar in + +0:17:09.199,0:17:12.720 +ideas + +0:17:11.280,0:17:14.799 +i'm not sure if that answers the + +0:17:12.720,0:17:15.919 +question but like so far i've been using + +0:17:14.799,0:17:17.919 +the orgrum + +0:17:15.919,0:17:19.039 +you know the default way which is like + +0:17:17.919,0:17:22.160 +many small + +0:17:19.039,0:17:24.400 +um files and then just + +0:17:22.160,0:17:26.319 +linking them to my like either if i have + +0:17:24.400,0:17:26.959 +a report to write or if i have a like + +0:17:26.319,0:17:32.240 +you know + +0:17:26.959,0:17:35.360 +essay to write + +0:17:32.240,0:17:37.760 +i think you're muted + +0:17:35.360,0:17:38.400 +q and i just i did two stupid things the + +0:17:37.760,0:17:40.640 +first one + +0:17:38.400,0:17:42.320 +was filling up my water the second one + +0:17:40.640,0:17:43.760 +was peeking without actually turning on + +0:17:42.320,0:17:45.760 +my microphone + +0:17:43.760,0:17:47.760 +so let's just hope that nothing is going + +0:17:45.760,0:17:48.320 +to fry in the near vicinity of me right + +0:17:47.760,0:17:49.840 +now + +0:17:48.320,0:17:51.440 +but uh yeah i believe you've answered + +0:17:49.840,0:17:53.200 +the question so don't worry about it i'm + +0:17:51.440,0:17:55.280 +slightly wet right now which is not a + +0:17:53.200,0:17:57.280 +very agreeable feeling but we'll have to + +0:17:55.280,0:17:59.360 +carry on i suppose + +0:17:57.280,0:18:01.600 +another question is there a place where + +0:17:59.360,0:18:04.320 +people are collaborating on research + +0:18:01.600,0:18:06.160 +about emacs so do you want to try to + +0:18:04.320,0:18:08.559 +take this one + +0:18:06.160,0:18:10.559 +um i don't know but i'm definitely + +0:18:08.559,0:18:12.480 +interested in the user experience of + +0:18:10.559,0:18:14.720 +emacs so + +0:18:12.480,0:18:16.400 +if anyone wants to work on that i'm + +0:18:14.720,0:18:18.320 +happy + +0:18:16.400,0:18:19.760 +well you do have a a pretty good + +0:18:18.320,0:18:22.080 +candidate in front of you if i + +0:18:19.760,0:18:22.960 +should say so myself i'm incredibly + +0:18:22.080,0:18:25.039 +interested about + +0:18:22.960,0:18:26.960 +um the ability to do research in emacs + +0:18:25.039,0:18:30.480 +and about the ability to + +0:18:26.960,0:18:32.480 +um preach the floss way + +0:18:30.480,0:18:34.080 +to academia and to the academe + +0:18:32.480,0:18:35.280 +especially because i believe there's + +0:18:34.080,0:18:38.240 +really something + +0:18:35.280,0:18:39.919 +great to be done sorry i'm just looking + +0:18:38.240,0:18:41.840 +at the puddle of water on the side which + +0:18:39.919,0:18:45.039 +is slightly oozing my way + +0:18:41.840,0:18:46.880 +which is not a very good feeling really + +0:18:45.039,0:18:48.320 +but yeah i believe i believe some work + +0:18:46.880,0:18:50.000 +could be done and if people are + +0:18:48.320,0:18:52.320 +interested in the chat right now + +0:18:50.000,0:18:53.440 +i mean do get in touch with us both + +0:18:52.320,0:18:56.480 +neuron and i + +0:18:53.440,0:18:57.280 +are on our slack channel yes i know + +0:18:56.480,0:19:00.080 +slack + +0:18:57.280,0:19:01.919 +the corporate hive mind that it's like + +0:19:00.080,0:19:02.720 +but we've decided with orgrim to use + +0:19:01.919,0:19:05.520 +slack + +0:19:02.720,0:19:06.880 +but you can find us very easily and uh + +0:19:05.520,0:19:07.360 +if you want to talk about these topics + +0:19:06.880,0:19:08.720 +yes + +0:19:07.360,0:19:10.720 +by all means do and we'll be very + +0:19:08.720,0:19:12.640 +interested to answer your questions + +0:19:10.720,0:19:15.520 +so i have a question here says like how + +0:19:12.640,0:19:18.640 +does the view for time blocking works + +0:19:15.520,0:19:22.000 +um i use org super agenda so + +0:19:18.640,0:19:23.200 +um what happens is that my active + +0:19:22.000,0:19:26.960 +timestamps are + +0:19:23.200,0:19:29.200 +only in my gmail or file + +0:19:26.960,0:19:30.080 +so if you use org gcal you have to + +0:19:29.200,0:19:32.559 +specify + +0:19:30.080,0:19:34.320 +a certain org file and when it you know + +0:19:32.559,0:19:35.679 +imports them it imports them as like + +0:19:34.320,0:19:38.400 +active + +0:19:35.679,0:19:40.480 +timestamps and i make sure whenever i + +0:19:38.400,0:19:42.480 +create a to-do or even a research task + +0:19:40.480,0:19:45.039 +that it doesn't have a time stamp on it + +0:19:42.480,0:19:48.480 +because what i want to do is go back + +0:19:45.039,0:19:50.160 +and then move around um these tags + +0:19:48.480,0:19:51.919 +according to my you know either weekly + +0:19:50.160,0:19:52.960 +schedule or monthly or however long you + +0:19:51.919,0:19:56.480 +want to do it + +0:19:52.960,0:19:59.679 +um so yeah only active timestamps or + +0:19:56.480,0:20:03.280 +deadlines um appear in your time grid + +0:19:59.679,0:20:05.440 +so that could work um that's very good + +0:20:03.280,0:20:06.320 +just just to uh interject for a second + +0:20:05.440,0:20:07.840 +about this + +0:20:06.320,0:20:10.720 +you know with orgrim right now we're + +0:20:07.840,0:20:13.039 +mostly uh focused on optimization + +0:20:10.720,0:20:14.720 +but we're hoping to move on to ux very + +0:20:13.039,0:20:16.720 +soon so all those matters about + +0:20:14.720,0:20:18.159 +you know having to do's in your files it + +0:20:16.720,0:20:20.000 +is something that we've been thinking + +0:20:18.159,0:20:20.880 +about with jethro kwan who is my main + +0:20:20.000,0:20:23.280 +commentator + +0:20:20.880,0:20:24.480 +or grow and we'll be working on this in + +0:20:23.280,0:20:26.080 +the coming months so don't worry too + +0:20:24.480,0:20:29.760 +much about it and stay

i tried to rename the file + +0:00:27.439,0:00:31.599 +and it didn't work + +0:00:28.800,0:00:32.559 +well it turns out uh i had two file name + +0:00:31.599,0:00:34.480 +baz so +

this presentation + +0:00:40.239,0:00:44.399 +is that i'm going to oops i didn't stop + +0:00:43.040,0:00:47.520 +my timer just give me + +0:00:44.399,0:00:50.719 +a little second and let's subtract + +0:00:47.520,0:00:52.239 +one minute okay good so + +0:00:50.719,0:00:54.079 +what i'm going to do right now it's a + +0:00:52.239,0:00:56.879 +little different from the previous + +0:00:54.079,0:00:58.239 +talk i've gave you and different even + +0:00:56.879,0:01:00.480 +from what nura gave you + +0:00:58.239,0:01:02.399 +there's like uh scaling the mountain as + +0:01:00.480,0:01:03.359 +far as difficulty is concerned and on + +0:01:02.399,0:01:04.879 +this one + +0:01:03.359,0:01:06.799 +i will be telling you about the + +0:01:04.879,0:01:09.360 +technical aspects of orgrim + +0:01:06.799,0:01:11.119 +because you know i've been telling you + +0:01:09.360,0:01:13.119 +about the general philosophy + +0:01:11.119,0:01:14.560 +of the notes and the general philosophy + +0:01:13.119,0:01:16.159 +of organization + +0:01:14.560,0:01:18.479 +but right now i really want to get into + +0:01:16.159,0:01:22.640 +the nitty gritty about or grow + +0:01:18.479,0:01:25.759 +so if we go in the git repository + +0:01:22.640,0:01:27.920 +this at the very core is all grown and + +0:01:25.759,0:01:28.960 +for some of you who have no experience + +0:01:27.920,0:01:31.280 +whatsoever + +0:01:28.960,0:01:32.880 +uh developing stuff or programming or + +0:01:31.280,0:01:36.000 +anything along those lines + +0:01:32.880,0:01:36.720 +this is how all the development around + +0:01:36.000,0:01:40.000 +the world + +0:01:36.720,0:01:42.159 +is working you have a repository a + +0:01:40.000,0:01:44.399 +git repository where you have all the + +0:01:42.159,0:01:46.399 +files all the libraries you're using + +0:01:44.399,0:01:48.720 +all the programs all the commands + +0:01:46.399,0:01:52.240 +everything is inside your files + +0:01:48.720,0:01:53.759 +and in a way this is the organ project + +0:01:52.240,0:01:55.600 +you can see that we have many files we + +0:01:53.759,0:01:57.040 +have organ buffer capture compat + +0:01:55.600,0:02:00.399 +completion dailies + +0:01:57.040,0:02:02.000 +etc etc so + +0:02:00.399,0:02:04.079 +before we dive a little deeper i just + +0:02:02.000,0:02:04.640 +want to give you a lay of the land so to + +0:02:04.079,0:02:08.160 +speak to + +0:02:04.640,0:02:11.680 +to know where we're heading so + +0:02:08.160,0:02:15.599 +orgro is built on top of old mode + +0:02:11.680,0:02:17.760 +and org mode gives us plenty of tools + +0:02:15.599,0:02:18.800 +to play around with the files i'm moving + +0:02:17.760,0:02:20.080 +the glass i'm + +0:02:18.800,0:02:21.360 +i'm starting to move my hands a little + +0:02:20.080,0:02:22.959 +bit you know when i get excited about + +0:02:21.360,0:02:26.640 +something i move my hand + +0:02:22.959,0:02:29.360 +and then that stuff happens so + +0:02:26.640,0:02:31.360 +in all chrome we have org mode and + +0:02:29.360,0:02:33.360 +augment gives us plenty of tools which + +0:02:31.360,0:02:36.560 +are incredibly useful + +0:02:33.360,0:02:37.440 +for writing stuff so you know we already + +0:02:36.560,0:02:39.440 +have the links + +0:02:37.440,0:02:40.560 +we already have the hierarchy which is + +0:02:39.440,0:02:43.360 +given by having + +0:02:40.560,0:02:43.760 +trees within trees within trees we have + +0:02:43.360,0:02:45.760 +uh + +0:02:43.760,0:02:48.000 +quote blocks we have babel blocks we + +0:02:45.760,0:02:49.680 +have so much stuff we have an arsenal of + +0:02:48.000,0:02:53.519 +tools that have been developed + +0:02:49.680,0:02:56.640 +for the last 15 years and + +0:02:53.519,0:02:59.760 +when you think about it all chrome just + +0:02:56.640,0:03:01.360 +wants to create backlinks but it sounds + +0:02:59.760,0:03:02.239 +something very simple but the problem is + +0:03:01.360,0:03:05.519 +that we need + +0:03:02.239,0:03:06.400 +to play nicely with all of those + +0:03:05.519,0:03:09.360 +intricate + +0:03:06.400,0:03:10.879 +pieces and the fact is it takes quite a + +0:03:09.360,0:03:11.440 +lot of expertise to be able to do so + +0:03:10.879,0:03:14.400 +because + +0:03:11.440,0:03:15.200 +if right now we are in the brain of all + +0:03:14.400,0:03:18.959 +grow + +0:03:15.200,0:03:21.599 +but if i show you the brain of org mode + +0:03:18.959,0:03:23.280 +so this is the brain of org mode and it + +0:03:21.599,0:03:25.519 +looks very simple like this because i + +0:03:23.280,0:03:28.000 +haven't entered the less folder + +0:03:25.519,0:03:29.120 +but i'm just going to enter it i'm going + +0:03:28.000,0:03:32.000 +to + +0:03:29.120,0:03:32.959 +zoom out a little bit don't worry if you + +0:03:32.000,0:03:35.519 +don't see everything + +0:03:32.959,0:03:37.519 +but i just want you to get a fear the + +0:03:35.519,0:03:41.280 +sheer feel of magnitude + +0:03:37.519,0:03:42.640 +that is um org mode so right now we are + +0:03:41.280,0:03:43.760 +in a very small size what i'm gonna do + +0:03:42.640,0:03:47.519 +i'm going to skip + +0:03:43.760,0:03:51.040 +one page okay one two + +0:03:47.519,0:03:52.319 +three we have let's just check how many + +0:03:51.040,0:03:54.640 +lines we have + +0:03:52.319,0:03:56.480 +okay let me just revert to a fairly + +0:03:54.640,0:03:58.560 +readable side + +0:03:56.480,0:03:59.599 +at the bottom you can see that we have + +0:03:58.560,0:04:00.959 +oh it's not showing because it's a + +0:03:59.599,0:04:03.840 +little small okay i'm just going to + +0:04:00.959,0:04:06.959 +resize the window a little bit + +0:04:03.840,0:04:08.720 +it's not showing up give me a second i + +0:04:06.959,0:04:10.159 +can't see how many lines i have okay so + +0:04:08.720,0:04:11.840 +let's do it to get away + +0:04:10.159,0:04:14.000 +i'm going to go back at the beginning of + +0:04:11.840,0:04:16.160 +the buffer and we're going to count + +0:04:14.000,0:04:17.840 +how many lines we have so the bottom in + +0:04:16.160,0:04:18.880 +a midi buffer and the mini buffer is + +0:04:17.840,0:04:22.320 +this area + +0:04:18.880,0:04:25.919 +we have 377 lines + +0:04:22.320,0:04:29.759 +which means 377 + +0:04:25.919,0:04:31.520 +libraries within org mode and mind you + +0:04:29.759,0:04:32.960 +that's not counting all the modules that + +0:04:31.520,0:04:36.240 +we have on the side which + +0:04:32.960,0:04:37.360 +come on top of volt mode now when you + +0:04:36.240,0:04:40.639 +try to think + +0:04:37.360,0:04:44.400 +about something so elemental + +0:04:40.639,0:04:45.520 +as links you have to think about how to + +0:04:44.400,0:04:48.560 +play well + +0:04:45.520,0:04:50.000 +with every single one of these modules + +0:04:48.560,0:04:53.759 +now obviously not + +0:04:50.000,0:04:56.080 +the 370 370. sometimes you know + +0:04:53.759,0:04:57.680 +one module it's not going to do anything + +0:04:56.080,0:04:58.639 +like i'm not sure op car could be doing + +0:04:57.680,0:05:00.080 +anything with it + +0:04:58.639,0:05:03.039 +but it's something that we have to keep + +0:05:00.080,0:05:04.720 +in mind and so + +0:05:03.039,0:05:07.520 +really early on when we started + +0:05:04.720,0:05:10.080 +developing all grown with jethro kwan my + +0:05:07.520,0:05:10.639 +co-maintainer you know we had this idea + +0:05:10.080,0:05:13.520 +that + +0:05:10.639,0:05:14.639 +we wanted to develop something that was + +0:05:13.520,0:05:18.240 +optimized + +0:05:14.639,0:05:20.160 +something that would you know scale very + +0:05:18.240,0:05:21.600 +nicely whether or not you had + +0:05:20.160,0:05:24.560 +you know something that would work as + +0:05:21.600,0:05:27.680 +fast if you had 10 files + +0:05:24.560,0:05:30.880 +or if you had 100 files or if you had + +0:05:27.680,0:05:32.080 +10 000 files and maybe more so the + +0:05:30.880,0:05:34.400 +problem when you do this + +0:05:32.080,0:05:36.320 +and i'm doing some callbacks to the talk + +0:05:34.400,0:05:41.280 +i gave you earlier today about + +0:05:36.320,0:05:44.800 +few small few big files this is many + +0:05:41.280,0:05:45.919 +i got confused few big files versus many + +0:05:44.800,0:05:49.280 +small files + +0:05:45.919,0:05:51.600 +the problem with this is that we need to + +0:05:49.280,0:05:53.680 +think about optimization from the get go + +0:05:51.600,0:05:54.800 +and so one of the decision we took when + +0:05:53.680,0:05:59.199 +we got started + +0:05:54.800,0:06:02.479 +with orgrum is that if i go in my + +0:05:59.199,0:06:04.240 +test repository so that's the one in + +0:06:02.479,0:06:08.000 +which we were right before + +0:06:04.240,0:06:11.600 +we have a file which is called orgrumdb + +0:06:08.000,0:06:14.160 +now if i open it it's not it's a + +0:06:11.600,0:06:15.120 +little garbage because uh it's a binary + +0:06:14.160,0:06:18.560 +but what we have + +0:06:15.120,0:06:21.919 +is a database with which we communicate + +0:06:18.560,0:06:25.120 +via sorry it's an sql database + +0:06:21.919,0:06:28.479 +and what this allows us to do + +0:06:25.120,0:06:31.919 +is we store all the information we need + +0:06:28.479,0:06:34.720 +inside this sql database which allows us + +0:06:31.919,0:06:35.360 +to speed up a lot of the operations that + +0:06:34.720,0:06:37.840 +are + +0:06:35.360,0:06:38.479 +necessary for the functioning of our + +0:06:37.840,0:06:40.240 +ground + +0:06:38.479,0:06:41.759 +so for instance if i go back to the + +0:06:40.240,0:06:43.440 +index file that i had before + +0:06:41.759,0:06:45.680 +let's just go back to who actually this + +0:06:43.440,0:06:47.919 +way you'll see a little more on the side + +0:06:45.680,0:06:48.720 +so you see that on the side we have + +0:06:47.919,0:06:50.319 +whoops + +0:06:48.720,0:06:51.759 +two links i'm not going to click on them + +0:06:50.319,0:06:53.199 +otherwise i'm going to open them but we + +0:06:51.759,0:06:56.319 +have two links + +0:06:53.199,0:06:58.240 +now there are many implementations of + +0:06:56.319,0:07:00.800 +the zettol casten method inside + +0:06:58.240,0:07:02.400 +emacs and inside and with old mode but + +0:07:00.800,0:07:04.639 +what we've decided to do + +0:07:02.400,0:07:05.520 +is that every time you have a link so if + +0:07:04.639,0:07:08.479 +we go to + +0:07:05.520,0:07:09.120 +the index again here at point we have + +0:07:08.479,0:07:12.400 +the link + +0:07:09.120,0:07:14.160 +foo every time we create a link we + +0:07:12.400,0:07:16.800 +update our database + +0:07:14.160,0:07:17.919 +to say okay so we have a link in the + +0:07:16.800,0:07:21.080 +file + +0:07:17.919,0:07:24.319 +index which is leading to the file + +0:07:21.080,0:07:27.840 +fu.org and it is situated + +0:07:24.319,0:07:29.840 +under the heading a heading and + +0:07:27.840,0:07:31.440 +if you check the site buffer you see + +0:07:29.840,0:07:33.120 +that all this all these information + +0:07:31.440,0:07:36.720 +which i just highlighted to you + +0:07:33.120,0:07:36.720 +are present right here + +0:07:42.639,0:07:46.400 +oh well sorry i forgot this thank you + +0:07:45.599,0:07:50.879 +okay + +0:07:46.400,0:07:53.039 +so let's see log okay i'm going to split + +0:07:50.879,0:07:54.960 +actually i'm going to split like this + +0:07:53.039,0:07:56.960 +i'm going to go back there + +0:07:54.960,0:07:58.720 +the problem is that i can't show my + +0:07:56.960,0:08:02.080 +keystrokes at the same time as a machine + +0:07:58.720,0:08:03.599 +i'm showing the site buffer so i'll + +0:08:02.080,0:08:05.199 +keep it right now for your own + +0:08:03.599,0:08:07.039 +discretion anyway getting back to the + +0:08:05.199,0:08:10.160 +talk + +0:08:07.039,0:08:12.720 +so the thing is we have this + +0:08:10.160,0:08:13.520 +sql database and the goal is to keep it + +0:08:12.720,0:08:16.400 +optimized + +0:08:13.520,0:08:17.039 +now why is it better optimized than just + +0:08:16.400,0:08:20.960 +using + +0:08:17.039,0:08:23.520 +orgrom sorry just using default org mode + +0:08:20.960,0:08:24.080 +so in my talk about many big files + +0:08:23.520,0:08:26.879 +versus + +0:08:24.080,0:08:28.080 +a few i keep getting you know you got + +0:08:26.879,0:08:29.120 +what i was saying i'm not going to + +0:08:28.080,0:08:32.240 +repeat it + +0:08:29.120,0:08:35.200 +by the way it is uh 10 to 10. + +0:08:32.240,0:08:36.399 +i'm starting really to be tired now so + +0:08:35.200,0:08:39.279 +uh moving on to + +0:08:36.399,0:08:40.800 +um what did i want to show you so it was + +0:08:39.279,0:08:44.959 +almost yes all the elements + +0:08:40.800,0:08:47.200 +so what i'm going to do i'm going to + +0:08:44.959,0:08:48.399 +see i believe it's org element pass + +0:08:47.200,0:08:51.040 +buffer + +0:08:48.399,0:08:51.920 +so i was telling you about all elements + +0:08:51.040,0:08:53.600 +before + +0:08:51.920,0:08:55.760 +and the main command sorry the main + +0:08:53.600,0:08:58.560 +function that is used by org element + +0:08:55.760,0:08:59.760 +is pass buffer what it does and you can + +0:08:58.560,0:09:01.040 +see the dock string is that it + +0:08:59.760,0:09:03.279 +recursively passed + +0:09:01.040,0:09:04.959 +the buffer and return structure + +0:09:03.279,0:09:06.320 +structure being all the information that + +0:09:04.959,0:09:07.680 +we have in this buffer + +0:09:06.320,0:09:09.600 +so just to show you a little more we're + +0:09:07.680,0:09:10.880 +going to move into a scratch buffer + +0:09:09.600,0:09:12.800 +and what we're going to do is that we're + +0:09:10.880,0:09:16.320 +going to write this command + +0:09:12.800,0:09:17.760 +pass buffer and we're going to check the + +0:09:16.320,0:09:19.600 +output of this command + +0:09:17.760,0:09:22.000 +oh sorry not this one we're going to go + +0:09:19.600,0:09:23.680 +in the index so the index file you have + +0:09:22.000,0:09:25.120 +a title you have a heading you have a + +0:09:23.680,0:09:26.880 +link etc etc + +0:09:25.120,0:09:28.560 +so what i'm going to do i'm going to + +0:09:26.880,0:09:30.800 +evaluate this text + +0:09:28.560,0:09:32.560 +and now at the bottom in the midi buffer + +0:09:30.800,0:09:36.160 +in the mini buffer sorry + +0:09:32.560,0:09:37.600 +you see an ast an abstract + +0:09:36.160,0:09:39.839 +obviously don't remember what the s + +0:09:37.600,0:09:42.720 +stands for semantic + +0:09:39.839,0:09:43.519 +huh interesting anyway a representation + +0:09:42.720,0:09:45.279 +of the data + +0:09:43.519,0:09:47.600 +in a way that is exploitable by a + +0:09:45.279,0:09:49.839 +machine now what i'm going to do + +0:09:47.600,0:09:52.000 +syntax thank you so what i'm going to do + +0:09:49.839,0:09:54.480 +i'm going to paste it inside the buffer + +0:09:52.000,0:09:56.399 +in a way that is humanly readable and + +0:09:54.480,0:09:58.800 +you can see that we have plenty of + +0:09:56.399,0:10:00.560 +information we have a section which + +0:09:58.800,0:10:05.040 +starts at the char + +0:10:00.560,0:10:07.040 +1 which ends at the character 45 + +0:10:05.040,0:10:08.240 +we have the content so he makes scratch + +0:10:07.040,0:10:10.240 +oh actually no + +0:10:08.240,0:10:11.279 +never mind i did something wrong i run + +0:10:10.240,0:10:13.040 +it in the wrong buffer + +0:10:11.279,0:10:14.399 +so actually what i'm going to do we're + +0:10:13.040,0:10:17.519 +going to run this command + +0:10:14.399,0:10:21.120 +with the selected window next + +0:10:17.519,0:10:23.760 +window okay that's a bit of live + +0:10:21.120,0:10:24.640 +elise writing for you right now okay so + +0:10:23.760,0:10:26.240 +now if i + +0:10:24.640,0:10:28.480 +evaluate this and paste the content of + +0:10:26.240,0:10:31.600 +the buffer + +0:10:28.480,0:10:32.399 +it is doing its bidding so now what we + +0:10:31.600,0:10:34.959 +have + +0:10:32.399,0:10:36.720 +we have a section we have the keyword + +0:10:34.959,0:10:38.160 +title which you see right here you have + +0:10:36.720,0:10:39.920 +the value + +0:10:38.160,0:10:41.360 +if we scroll down a little bit we have a + +0:10:39.920,0:10:42.480 +heading which is right here we have the + +0:10:41.360,0:10:44.800 +contents + +0:10:42.480,0:10:46.320 +which should be yes the content is not + +0:10:44.800,0:10:48.079 +listed exactly here but you have a + +0:10:46.320,0:10:50.640 +paragraph which is this + +0:10:48.079,0:10:51.200 +and then you have a link etc etc it is + +0:10:50.640,0:10:53.839 +all + +0:10:51.200,0:10:54.640 +uh parenthesis if you're not used to + +0:10:53.839,0:10:56.320 +e-list + +0:10:54.640,0:10:58.640 +like right now i've selected only the + +0:10:56.320,0:11:00.399 +content of the parenthesis link + +0:10:58.640,0:11:01.680 +i can move like this etcetera etcetera + +0:11:00.399,0:11:03.760 +i'm not it's not a needle + +0:11:01.680,0:11:05.279 +lessons that i'm doing right now but + +0:11:03.760,0:11:08.399 +basically + +0:11:05.279,0:11:09.120 +if we were to use the default tooling of + +0:11:08.399,0:11:10.880 +orgrom + +0:11:09.120,0:11:12.480 +org mode sorry i keep getting too + +0:11:10.880,0:11:14.240 +confused sorry for that + +0:11:12.480,0:11:16.399 +uh it would be extremely slow to do what + +0:11:14.240,0:11:19.760 +we're doing some people + +0:11:16.399,0:11:22.240 +are doing so some implementations of the + +0:11:19.760,0:11:23.040 +zettelkassen method inside emacs have + +0:11:22.240,0:11:26.480 +opted + +0:11:23.040,0:11:27.360 +for this method but the problem is that + +0:11:26.480,0:11:30.160 +we think + +0:11:27.360,0:11:30.560 +that it scales poorly now some other + +0:11:30.160,0:11:33.920 +people + +0:11:30.560,0:11:35.600 +have decided to not do with a database + +0:11:33.920,0:11:37.200 +and what they do is that they use a tool + +0:11:35.600,0:11:38.800 +which is called rip grep + +0:11:37.200,0:11:41.279 +you might know grep which is a tool that + +0:11:38.800,0:11:43.440 +allows you to search + +0:11:41.279,0:11:46.560 +a file the content of a file for a line + +0:11:43.440,0:11:49.680 +so for instance if we open v term here + +0:11:46.560,0:11:51.839 +uh let's see so i've opened the term i + +0:11:49.680,0:11:54.399 +am in this repository what i'm going to + +0:11:51.839,0:11:58.000 +do is that i'm going to + +0:11:54.399,0:12:00.480 +load the content of the file uh + +0:11:58.000,0:12:02.480 +how am i going to do this oh um i need + +0:12:00.480,0:12:06.160 +to move to bash + +0:12:02.480,0:12:08.000 +let's do crap + +0:12:06.160,0:12:09.519 +for the line which links do we did we + +0:12:08.000,0:12:11.600 +have grep foo + +0:12:09.519,0:12:13.760 +inside the file is it three i can + +0:12:11.600,0:12:16.880 +remember okay let's do this + +0:12:13.760,0:12:16.880 +am i working no + +0:12:18.079,0:12:22.800 +let's go for four why is it eight + +0:12:21.279,0:12:24.320 +ah damn it oh you know what i'm just + +0:12:22.800,0:12:28.240 +going to copy the name + +0:12:24.320,0:12:33.279 +up there we go no + +0:12:28.240,0:12:33.279 +ah problem with live presentation always + +0:12:33.680,0:12:36.720 +you know what i'm struggling so i'm + +0:12:34.800,0:12:38.560 +going to drop this point anyway + +0:12:36.720,0:12:40.000 +so grep is a simple tool that allows you + +0:12:38.560,0:12:42.480 +to search the content of a file but + +0:12:40.000,0:12:44.160 +rig grep is a solution that is written + +0:12:42.480,0:12:45.920 +in rust and which is supposed to be + +0:12:44.160,0:12:48.880 +well not supposed which is far more + +0:12:45.920,0:12:50.639 +capable now + +0:12:48.880,0:12:52.320 +i'd like to talk to you about the future + +0:12:50.639,0:12:54.720 +of orgrim right now i've told you about + +0:12:52.320,0:12:58.399 +the general concept which is about using + +0:12:54.720,0:13:01.519 +uh this sql database and about + +0:12:58.399,0:13:03.279 +playing nicely with old mode but + +0:13:01.519,0:13:05.200 +we think that there's something great + +0:13:03.279,0:13:08.320 +that we can do about orgrim + +0:13:05.200,0:13:10.320 +now i've been talking with the a lot of + +0:13:08.320,0:13:10.880 +people who are behind org mode and you + +0:13:10.320,0:13:14.000 +know + +0:13:10.880,0:13:16.880 +they've told us do you think that + +0:13:14.000,0:13:18.320 +orgrom could have something to bring to + +0:13:16.880,0:13:20.160 +old mode let's say + +0:13:18.320,0:13:21.600 +backlinks is there something that we + +0:13:20.160,0:13:25.600 +could be doing to + +0:13:21.600,0:13:27.200 +import backlinks into old mode and + +0:13:25.600,0:13:29.200 +we thought about it with jethro and the + +0:13:27.200,0:13:30.800 +problem is uh + +0:13:29.200,0:13:32.720 +we've always tried to have an + +0:13:30.800,0:13:35.360 +experimental ground a very + +0:13:32.720,0:13:36.320 +uh can a very isolated portion of your + +0:13:35.360,0:13:37.920 +system + +0:13:36.320,0:13:40.320 +where we could track backlinks and + +0:13:37.920,0:13:42.320 +that's why we use um + +0:13:40.320,0:13:44.880 +a slipbox directory so that we only + +0:13:42.320,0:13:47.040 +track backlinks in one specific place + +0:13:44.880,0:13:48.639 +but now because there seems to be so + +0:13:47.040,0:13:50.079 +much interest about the method and we + +0:13:48.639,0:13:52.480 +have so much backing + +0:13:50.079,0:13:53.120 +on uh you know on github we have like + +0:13:52.480,0:13:56.399 +200 + +0:13:53.120,0:13:59.760 +2 600 stars which is mind-boggling to us + +0:13:56.399,0:14:02.399 +because we have so much success but + +0:13:59.760,0:14:03.360 +we have plenty of ideas about the future + +0:14:02.399,0:14:06.000 +one of the key + +0:14:03.360,0:14:08.480 +parts of development being the writing + +0:14:06.000,0:14:09.680 +of an external parser for orgrim + +0:14:08.480,0:14:11.839 +so i've been telling you about org + +0:14:09.680,0:14:15.279 +element org elements runs + +0:14:11.839,0:14:19.519 +inside emacs but what if + +0:14:15.279,0:14:23.600 +we wrote a background process + +0:14:19.519,0:14:25.760 +that could read a file an augment file + +0:14:23.600,0:14:27.440 +extract the same type of data that you + +0:14:25.760,0:14:30.240 +see on your screen right now + +0:14:27.440,0:14:30.959 +so that we could use to update a + +0:14:30.240,0:14:33.279 +database + +0:14:30.959,0:14:34.959 +so that we could use to compute the + +0:14:33.279,0:14:37.360 +links so that we could use it + +0:14:34.959,0:14:39.519 +to show you know orgrim server all the + +0:14:37.360,0:14:41.360 +connections between your nodes + +0:14:39.519,0:14:44.320 +now there is a path of improvement here + +0:14:41.360,0:14:47.360 +that is extremely important to us + +0:14:44.320,0:14:48.639 +but you know that's the technical aspect + +0:14:47.360,0:14:50.079 +and i'm out of time i'm just going to + +0:14:48.639,0:14:51.360 +take one more minute to finish on this + +0:14:50.079,0:14:54.560 +point + +0:14:51.360,0:14:57.680 +but we believe + +0:14:54.560,0:14:58.399 +that orgrim has the potential to be a + +0:14:57.680,0:15:00.639 +think tank + +0:14:58.399,0:15:01.920 +in a way for org mode and the way we + +0:15:00.639,0:15:04.079 +think about + +0:15:01.920,0:15:06.079 +note-taking in general i've stressed a + +0:15:04.079,0:15:10.240 +great deal in my first presentation + +0:15:06.079,0:15:12.480 +sorry the one i did before neura that + +0:15:10.240,0:15:14.639 +all chrome is really great as a way to + +0:15:12.480,0:15:17.600 +think organically about knowledge + +0:15:14.639,0:15:19.279 +and honestly we kind of want to put the + +0:15:17.600,0:15:22.079 +theory into practice with orgrim + +0:15:19.279,0:15:23.440 +we are holding something which has the + +0:15:22.079,0:15:25.120 +potential to be + +0:15:23.440,0:15:27.279 +a great factor of innovation for the + +0:15:25.120,0:15:29.600 +future whether it be or org mode + +0:15:27.279,0:15:31.440 +or even for software in general you know + +0:15:29.600,0:15:34.880 +the way to think about + +0:15:31.440,0:15:37.440 +build nodes of knowledge in a way + +0:15:34.880,0:15:38.240 +and the way to represent all those ids + +0:15:37.440,0:15:40.560 +with the graph + +0:15:38.240,0:15:41.600 +the way to basically have a note-taking + +0:15:40.560,0:15:43.360 +system that + +0:15:41.600,0:15:45.839 +corresponds to the research that + +0:15:43.360,0:15:49.120 +corresponds to the way you think + +0:15:45.839,0:15:51.839 +so yeah i believe we are + +0:15:49.120,0:15:53.519 +really excited about this and if you + +0:15:51.839,0:15:55.360 +want to keep track of the development of + +0:15:53.519,0:15:57.600 +all chrome + +0:15:55.360,0:15:59.279 +i on my youtube channel which is already + +0:15:57.600,0:16:02.639 +linked a little earlier + +0:15:59.279,0:16:04.240 +inside this present inside the pad sorry + +0:16:02.639,0:16:06.079 +i do have a youtube channel where i try + +0:16:04.240,0:16:09.519 +to present novelties + +0:16:06.079,0:16:11.519 +or the new stuff inside um orgrim + +0:16:09.519,0:16:13.360 +but i also be recording videos about the + +0:16:11.519,0:16:15.519 +technical aspects about the direction + +0:16:13.360,0:16:18.000 +that we're taking with orgrim + +0:16:15.519,0:16:18.560 +and if you want to talk with us we are + +0:16:18.000,0:16:22.160 +always + +0:16:18.560,0:16:23.680 +available either on isc channel orgrom + +0:16:22.160,0:16:25.279 +i believe there's a dash between org and + +0:16:23.680,0:16:27.279 +rome but also + +0:16:25.279,0:16:29.440 +on the discourse and i'll be putting all + +0:16:27.279,0:16:31.199 +the links inside the conversation + +0:16:29.440,0:16:32.880 +and that's me done so thank you for + +0:16:31.199,0:16:34.560 +listening and now i'll be taking + +0:16:32.880,0:16:37.360 +three minutes of questions so as to be + +0:16:34.560,0:16:39.920 +right on time + +0:16:37.360,0:16:41.120 +mini thanks for your awesome talk leo + +0:16:39.920,0:16:43.040 +thank you + +0:16:41.120,0:16:44.959 +so i'm just refreshing the page and i'm + +0:16:43.040,0:16:49.279 +going to scroll down to my + +0:16:44.959,0:16:49.279 +talk if i can find the right section + +0:16:49.600,0:16:52.720 +let me just scroll a little bit + +0:16:53.120,0:16:57.120 +uh reproducible emacs no i think it's + +0:16:55.600,0:16:59.279 +slower + +0:16:57.120,0:17:00.639 +god we have so many questions so at the + +0:16:59.279,0:17:01.120 +same time i'm pissed because i can't + +0:17:00.639,0:17:02.639 +find it + +0:17:01.120,0:17:05.360 +but i'm really really impressed by the + +0:17:02.639,0:17:07.760 +number of questions that we had oh yeah + +0:17:05.360,0:17:08.260 +um which is about i think about line 600 + +0:17:07.760,0:17:09.919 +or so + +0:17:08.260,0:17:13.199 +[Music] + +0:17:09.919,0:17:16.400 +yes got it splendid + +0:17:13.199,0:17:18.160 +so um the questions so why not run a + +0:17:16.400,0:17:19.919 +background emacs for passing instead of + +0:17:18.160,0:17:22.559 +implementing a new parser + +0:17:19.919,0:17:24.480 +so i believe we've had this question uh + +0:17:22.559,0:17:27.600 +i was giving a similar talk + +0:17:24.480,0:17:31.679 +earlier this week and this week + +0:17:27.600,0:17:33.280 +i'm not french this week sorry and + +0:17:31.679,0:17:35.679 +someone asked me this question and the + +0:17:33.280,0:17:38.320 +thing is running a background emacs + +0:17:35.679,0:17:40.400 +process you know it sounds great + +0:17:38.320,0:17:41.760 +but it's also very limited because all + +0:17:40.400,0:17:45.520 +the problems we have + +0:17:41.760,0:17:48.160 +about concurrency about threads in emacs + +0:17:45.520,0:17:49.200 +well yes we can forward all our calls to + +0:17:48.160,0:17:51.760 +background emacs + +0:17:49.200,0:17:52.240 +just like uh you know when you export a + +0:17:51.760,0:17:56.400 +file + +0:17:52.240,0:17:57.840 +with uh um sorry + +0:17:56.400,0:17:58.799 +i mean could you mute microphone when + +0:17:57.840,0:18:01.520 +you're speaking it's a little hard for + +0:17:58.799,0:18:03.600 +me to concentrate + +0:18:01.520,0:18:04.640 +that's fine don't worry you are now uh + +0:18:03.600,0:18:06.960 +so um + +0:18:04.640,0:18:07.679 +dammit where was i i'm sorry the + +0:18:06.960,0:18:09.280 +question yes + +0:18:07.679,0:18:11.840 +so basically forwarding all the + +0:18:09.280,0:18:13.039 +questions uh sorry all our queries to uh + +0:18:11.840,0:18:16.000 +background emacs + +0:18:13.039,0:18:17.960 +that is what uh org export is doing like + +0:18:16.000,0:18:20.799 +you have the ability to + +0:18:17.960,0:18:22.080 +asynchronously export latex documents + +0:18:20.799,0:18:24.480 +odt documents from + +0:18:22.080,0:18:26.000 +org mode and it uses a very minimal + +0:18:24.480,0:18:28.240 +version of emacs to do that but the + +0:18:26.000,0:18:30.320 +problem is that we think that it's not + +0:18:28.240,0:18:33.039 +going to scale as well as a true + +0:18:30.320,0:18:34.480 +genuine background process and since we + +0:18:33.039,0:18:36.000 +have been talking a lot + +0:18:34.480,0:18:38.160 +as far as the old mode development is + +0:18:36.000,0:18:40.640 +concerned about + +0:18:38.160,0:18:41.760 +writing a proper parser writing a proper + +0:18:40.640,0:18:43.440 +documentation + +0:18:41.760,0:18:46.000 +for the passing of old mode file and + +0:18:43.440,0:18:48.400 +writing a proper document standard + +0:18:46.000,0:18:50.000 +that says okay this is how the old mode + +0:18:48.400,0:18:52.000 +format works you know to + +0:18:50.000,0:18:55.120 +basically have a way to not fall into + +0:18:52.000,0:18:56.559 +the traps of markdown which has many + +0:18:55.120,0:18:58.480 +many standards + +0:18:56.559,0:19:00.000 +we need to think about this and we + +0:18:58.480,0:19:01.360 +believe that all grown has + +0:19:00.000,0:19:03.120 +the ability to think about these + +0:19:01.360,0:19:04.640 +questions and as a + +0:19:03.120,0:19:06.400 +as a person i'm also really interested + +0:19:04.640,0:19:07.840 +about this so + +0:19:06.400,0:19:10.160 +i can take the question i mean so don't + +0:19:07.840,0:19:11.760 +worry about feeding them to me so how + +0:19:10.160,0:19:13.679 +often does the + +0:19:11.760,0:19:14.799 +db index get updated in order to contain + +0:19:13.679,0:19:17.360 +changes within the + +0:19:14.799,0:19:19.440 +files so we have two ways either we + +0:19:17.360,0:19:22.160 +update as soon as you save a file + +0:19:19.440,0:19:23.600 +or we have a timer which is an idle + +0:19:22.160,0:19:25.600 +timer which waits okay + +0:19:23.600,0:19:26.960 +the user has not imputed inputted + +0:19:25.600,0:19:29.360 +anything in the last + +0:19:26.960,0:19:30.080 +five seconds so it's time to queue a + +0:19:29.360,0:19:33.039 +database + +0:19:30.080,0:19:33.919 +passing a rebuild of the data not a an + +0:19:33.039,0:19:37.120 +incrementation + +0:19:33.919,0:19:38.799 +of the database i should say so + +0:19:37.120,0:19:40.320 +did you ever think of uh i believe i + +0:19:38.799,0:19:42.240 +have one more one more minutes and then + +0:19:40.320,0:19:43.440 +i'll hand it to the other folks + +0:19:42.240,0:19:45.440 +do you ever think of opening up or + +0:19:43.440,0:19:47.200 +designing the sqldb as a general all + +0:19:45.440,0:19:48.160 +speed up tool outside of orgrom so that + +0:19:47.200,0:19:49.919 +other libraries + +0:19:48.160,0:19:51.679 +that do execute complex queries are able + +0:19:49.919,0:19:52.960 +to use it well + +0:19:51.679,0:19:54.640 +a lot of people have been working on + +0:19:52.960,0:19:56.480 +this and i believe alpha papa has been + +0:19:54.640,0:19:57.679 +thinking quite a lot about this you know + +0:19:56.480,0:20:01.120 +all ql + +0:19:57.679,0:20:03.679 +is the ql stands for language + +0:20:01.120,0:20:04.720 +and i i can't remember now what's uh + +0:20:03.679,0:20:08.080 +what's the backend + +0:20:04.720,0:20:10.080 +is for all ql but the idea is relatively + +0:20:08.080,0:20:13.039 +relatively the same you know it's about + +0:20:10.080,0:20:14.880 +finding ways to optimize the way we + +0:20:13.039,0:20:16.640 +store the data about an old mode file + +0:20:14.880,0:20:20.400 +and how we retrieve it + +0:20:16.640,0:20:22.159 +and sql for us seems to seem to be a + +0:20:20.400,0:20:24.240 +good idea now obviously + +0:20:22.159,0:20:26.080 +maybe we could do something about old + +0:20:24.240,0:20:27.360 +mode but the problem is i think a + +0:20:26.080,0:20:30.799 +background process + +0:20:27.360,0:20:32.960 +is not necessarily um in + +0:20:30.799,0:20:34.000 +the core mentality of old mode but it's + +0:20:32.960,0:20:36.080 +definitely a + +0:20:34.000,0:20:37.679 +something that we could suggest uh when + +0:20:36.080,0:20:40.960 +we are a little more mature because well + +0:20:37.679,0:20:41.679 +orgrom was started last february and so + +0:20:40.960,0:20:44.480 +it's a fairly + +0:20:41.679,0:20:45.840 +young project in a way so uh i see + +0:20:44.480,0:20:48.400 +plenty more questions but + +0:20:45.840,0:20:50.559 +i'm out of time folks so i'm not sure uh + +0:20:48.400,0:20:52.559 +the other speaker is probably ready + +0:20:50.559,0:20:54.000 +so what i'll do is i'll probably try to + +0:20:52.559,0:20:55.360 +answer your questions when i get the + +0:20:54.000,0:20:58.960 +time inside the pad + +0:20:55.360,0:21:01.039 +but feel free to ping me on isc + +0:20:58.960,0:21:02.320 +or on the different channels we have + +0:21:01.039,0:21:04.000

+webbery + +0:00:08.480,0:00:12.240 +the essential idea behind org webbering + +0:00:10.559,0:00:13.679 +is to take the power of creating a + +0:00:12.240,0:00:15.360 +website with org mode +

acquire + +0:01:05.360,0:01:07.760 +and place the information in the correct + +0:01:07.040,0:01:10.000 +format + +0:01:07.760,0:01:10.799 +according to your specification + +0:01:10.000,0:01:11.840 +additionally + +0:01:10.799,0:01:14.159 +you can see that the geeksday + +0:01:11.840,0:01:16.000 +announcement is post is pinned + +0:01:14.159,0:01:17.200 +stylization is likewise controlled by + +0:01:16.000,0:01:18.960 +using css + +0:01:17.200,0:01:20.720 +you can add nice subtle color changes on + +0:01:18.960,0:01:23.759 +mouse hover or control the size of the + +0:01:20.720,0:01:26.080 +flexboxes all using standard css + +0:01:23.759,0:01:28.320 +let's examine a simple scenario of using + +0:01:26.080,0:01:30.400 +org webroom + +0:01:28.320,0:01:32.000 +after you have org webbing installed + +0:01:30.400,0:01:33.759 +you'll be able to create a manifest file + +0:01:32.000,0:01:35.680 +that looks something like this + +0:01:33.759,0:01:37.840 +this particular manifest file is an + +0:01:35.680,0:01:39.520 +example offered in the repository under + +0:01:37.840,0:01:41.200 +the assets directory + +0:01:39.520,0:01:42.640 +please feel free to utilize them as a + +0:01:41.200,0:01:44.399 +starting point if you are interested in + +0:01:42.640,0:01:46.320 +using org web ring + +0:01:44.399,0:01:48.640 +as you can see here we are able to place + +0:01:46.320,0:01:50.479 +an rss or atom feed in this file and + +0:01:48.640,0:01:51.920 +specify information about the feed we + +0:01:50.479,0:01:54.640 +wish to produce + +0:01:51.920,0:01:56.159 +for example the total number of items + +0:01:54.640,0:01:57.439 +and the total number of entries per + +0:01:56.159,0:01:59.439 +source item + +0:01:57.439,0:02:00.960 +additionally you're able to filter posts + +0:01:59.439,0:02:02.079 +you feel would not be relevant to your + +0:02:00.960,0:02:04.079 +web ring + +0:02:02.079,0:02:09.840 +we can take this example file and run + +0:02:04.079,0:02:09.840 +the dispatch and see the result + +0:02:13.120,0:02:17.760 +the web ring displays a proper summary + +0:02:15.280,0:02:19.599 +set to a character limit you can specify + +0:02:17.760,0:02:21.520 +additionally all the links in the web + +0:02:19.599,0:02:22.560 +ring are navigable and will open in a + +0:02:21.520,0:02:24.239 +new tab + +0:02:22.560,0:02:25.920 +that way if someone wishes to view the + +0:02:24.239,0:02:30.319 +content they simply need to + +0:02:25.920,0:02:32.879 +click on the title or their source name + +0:02:30.319,0:02:34.800 +now this particular example is not + +0:02:32.879,0:02:37.120 +stylized because we have not given the + +0:02:34.800,0:02:38.720 +website a css file to reference + +0:02:37.120,0:02:40.319 +let's examine what is happening from + +0:02:38.720,0:02:43.040 +behind the scenes a little bit + +0:02:40.319,0:02:43.360 +from inside of the org mode file let's + +0:02:43.040,0:02:46.959 +run + +0:02:43.360,0:02:46.959 +the org web ring function + +0:02:48.800,0:02:54.239 +as you can see it takes that xml file + +0:02:51.280,0:02:56.080 +and processes it into the correct html + +0:02:54.239,0:02:58.080 +you will then be able to embed this org + +0:02:56.080,0:03:00.080 +function into another org file to be + +0:02:58.080,0:03:02.840 +able to display it on your website + +0:03:00.080,0:03:05.440 +pretty neat let's look at an at another + +0:03:02.840,0:03:07.360 +example + +0:03:05.440,0:03:09.519 +on my website we have an example of + +0:03:07.360,0:03:10.800 +using org webbring to reply to another + +0:03:09.519,0:03:12.480 +blog post + +0:03:10.800,0:03:14.640 +what i have here is a post from drew to + +0:03:12.480,0:03:16.239 +vault's blog it is showcased clearly at + +0:03:14.640,0:03:19.040 +the top as a single entry + +0:03:16.239,0:03:20.800 +and you can see it is pinned the pinning + +0:03:19.040,0:03:22.400 +functionality ensures that this post is + +0:03:20.800,0:03:23.120 +moved to the front of the hypothetical + +0:03:22.400,0:03:25.760 +web ring + +0:03:23.120,0:03:27.599 +and guaranteeing its visibility this is + +0:03:25.760,0:03:29.840 +then coupled with a few changes such as + +0:03:27.599,0:03:31.120 +disabling the generation time + +0:03:29.840,0:03:33.280 +which would not be relevant to the +

+language theory and category theory + +0:04:11.360,0:04:13.920 +primarily + +0:04:12.239,0:04:15.840 +it works in essentially the same way as + +0:04:13.920,0:04:17.519 +the org web ring you provide it with a + +0:04:15.840,0:04:20.000 +list of feeds that get parsed + +0:04:17.519,0:04:21.919 +however unlike the web ring the planet + +0:04:20.000,0:04:23.040 +function has no limits on the number of + +0:04:21.919,0:04:24.639 +entries per source + +0:04:23.040,0:04:27.600 +and the display number of posts is + +0:04:24.639,0:04:29.759 +increased significantly + +0:04:27.600,0:04:30.720 +the

+a planet is typically meant to be a + +0:04:35.440,0:04:38.639 +standalone page and not something you + +0:04:37.040,0:04:39.440 +would embed in another page like a web + +0:04:38.639,0:04:41.680 +ring + +0:04:39.440,0:04:43.600 +all this is provided under a single file + +0:04:41.680,0:04:45.280 +in the org web ring package as the code + +0:04:43.600,0:04:48.240 +reuse is quite high + +0:04:45.280,0:04:49.840 +aside from my own website we can view + +0:04:48.240,0:04:52.400 +the org web ring being used in neat + +0:04:49.840,0:04:54.320 +context with varying stylizations + +0:04:52.400,0:04:57.680 +here's a nice example from mikhail + +0:04:54.320,0:05:00.000 +kirilov at w96k.ru + +0:04:57.680,0:05:00.960 +featuring a four symmetrical flexbox + +0:05:00.000,0:05:02.720

to be done simply + +0:06:27.759,0:06:31.520 +from that same manifest file + +0:06:31.600,0:06:35.759 +now taking a moment to examine some of + +0:06:33.919,0:06:37.840 +the org web ring code + +0:06:35.759,0:06:40.160 +you can see it is all done in the same + +0:06:37.840,0:06:43.120 +e-lisp that everybody else is used to + +0:06:40.160,0:06:43.919 +now admittedly my e-lisp is not as +

+0:07:13.680,0:07:20.880 +taking the syntax apart + +0:07:17.120,0:07:24.240 +we're able to see that we can + +0:07:20.880,0:07:27.680 +fetch urls which are then parsed and + +0:07:24.240,0:07:28.479

+0:01:12.960,0:01:17.119 +sex paper links would go to that target + +0:01:15.759,0:01:20.000 +for example this one + +0:01:17.119,0:01:22.720 +is a hyperlink that points to a buffer + +0:01:20.000,0:01:25.040 +with demand paid for cat + +0:01:22.720,0:01:27.040 +and usually but not always after + +0:01:25.040,0:01:29.840 +following the hyperlink we can go back + +0:01:27.040,0:01:30.720 +by just skilling the the current buffer + +0:01:29.840,0:01:34.400 +that the hyperlink + +0:01:30.720,0:01:38.000 +created the target of the hyperlink + +0:01:34.400,0:01:41.360 +but this example here is badly behaved + +0:01:38.000,0:01:43.360 +if we execute it it creates a new frame + +0:01:41.360,0:01:44.640 +and to go back to the previous situation + +0:01:43.360,0:01:50.079 +we have to either + +0:01:44.640,0:01:50.079 +click here or type ctrl x50 + +0:01:52.840,0:01:57.520 +uh + +0:01:54.880,0:02:00.640 +so here are some examples of sex + +0:01:57.520,0:02:03.600 +hyperlinks using standard max functions + +0:02:00.640,0:02:04.880 +this third one is uh badly behaved in a + +0:02:03.600,0:02:08.879 +different way + +0:02:04.880,0:02:09.840 +if executed we the target is created in + +0:02:08.879,0:02:13.840 +the same window + +0:02:09.840,0:02:16.000 +as we are now but it also shows a lot of + +0:02:13.840,0:02:20.840 +garbage here in the aqua area so + +0:02:16.000,0:02:23.280 +the the current frame becomes a bit + +0:02:20.840,0:02:26.160 +messy + +0:02:23.280,0:02:28.319 +and well one of the first things that i + +0:02:26.160,0:02:30.720 +did when i was creating av + +0:02:28.319,0:02:31.680 +many many years ago was that i created + +0:02:30.720,0:02:34.840 +variants + +0:02:31.680,0:02:36.640 +of all these functions that were better + +0:02:34.840,0:02:38.640 +behaved + +0:02:36.640,0:02:40.480 +and they were better behaved in two + +0:02:38.640,0:02:43.040 +senses the obvious one + +0:02:40.480,0:02:43.680 +was that they they all created the + +0:02:43.040,0:02:45.840 +target + +0:02:43.680,0:02:48.720 +in the same window as before so i could + +0:02:45.840,0:02:51.040 +go back by just typing meta k + +0:02:48.720,0:02:52.879 +which is essentially just killed this + +0:02:51.040,0:02:55.200 +buffer + +0:02:52.879,0:02:56.480 +and well but i also implemented + +0:02:55.200,0:02:59.040 +something extra that + +0:02:56.480,0:02:59.840 +are the post back lists for example for + +0:02:59.040,0:03:03.599 +example these + +0:02:59.840,0:03:06.080 +extra arguments here are a postback list + +0:03:03.599,0:03:09.599 +and this extra arguments specify + +0:03:06.080,0:03:13.040 +position and the target buffer + +0:03:09.599,0:03:16.720 +and in this example this this spot + +0:03:13.040,0:03:18.239 +spec list means starting from the from + +0:03:16.720,0:03:20.560 +the beginning of the buffer + +0:03:18.239,0:03:22.239 +search for the first occurrence of this + +0:03:20.560,0:03:24.159 +string + +0:03:22.239,0:03:25.519 +after that after the beginning of the + +0:03:24.159,0:03:28.159 +buffer and then + +0:03:25.519,0:03:29.120 +search for the first occurrence of this + +0:03:28.159,0:03:33.760 +string + +0:03:29.120,0:03:36.560 +after that + +0:03:33.760,0:03:38.799 +eev also defines some hyperlinks that do + +0:03:36.560,0:03:41.280 +not create new buffers + +0:03:38.799,0:03:41.840 +uh here is the first example if i + +0:03:41.280,0:03:45.920 +execute + +0:03:41.840,0:03:46.959 +this one this one is a hyperlink to the + +0:03:45.920,0:03:50.720 +to the result + +0:03:46.959,0:03:52.959 +of running this show comment date uh + +0:03:50.720,0:03:55.040 +but instead of showing the result in the + +0:03:52.959,0:03:58.959 +new buffer the result is shown + +0:03:55.040,0:04:01.840 +here so if execute to this type link + +0:03:58.959,0:04:04.239 +the result of date the output of data is + +0:04:01.840,0:04:06.640 +shown in the echo area and if executed + +0:04:04.239,0:04:06.640 +again + +0:04:07.120,0:04:11.519 +it shows the result again and the result + +0:04:09.519,0:04:15.200 +changes every second + +0:04:11.519,0:04:18.720 +and if so this is a variant + +0:04:15.200,0:04:21.840 +of fine sh + +0:04:18.720,0:04:24.960 +uh find sh0 is the variant that + +0:04:21.840,0:04:28.080 +just shows the output in the echo area + +0:04:24.960,0:04:31.120 +and find sh shows the output in + +0:04:28.080,0:04:31.120 +a new buffer + +0:04:31.759,0:04:37.520 +and here is an example of a hyperlink + +0:04:35.919,0:04:40.000 +that + +0:04:37.520,0:04:41.280 +calls an external program if execute + +0:04:40.000,0:04:43.759 +this + +0:04:41.280,0:04:46.639 +it it calls google chrome to open a + +0:04:43.759,0:04:51.520 +certain url + +0:04:46.639,0:04:55.280 +here it is let's go back to mx + +0:04:51.520,0:04:58.479 +if execute this happening here + +0:04:55.280,0:04:58.880 +it invokes my favorite pdf viewer which + +0:04:58.479,0:05:02.560 +is + +0:04:58.880,0:05:07.440 +xpdf it makes xpdf + +0:05:02.560,0:05:07.440 +open this pdf page it is pdf + +0:05:07.759,0:05:15.199 +in this page and this other arguments + +0:05:10.880,0:05:19.120 +are ignored let me show how it works + +0:05:15.199,0:05:20.160 +here it is this is a an accept from a + +0:05:19.120,0:05:22.639 +book + +0:05:20.160,0:05:23.199 +so page 3 and the pdf corresponds to + +0:05:22.639,0:05:26.400 +page + +0:05:23.199,0:05:29.360 +113 in the book and + +0:05:26.400,0:05:31.759 +this variant here of the hyperlink above + +0:05:29.360,0:05:34.560 +it opens the pdf in a different way + +0:05:31.759,0:05:36.479 +it runs a program called pdf to text on + +0:05:34.560,0:05:39.600 +this pdf here + +0:05:36.479,0:05:42.880 +and max takes the output of + +0:05:39.600,0:05:46.080 +run epd after text on this pdf here + +0:05:42.880,0:05:47.280 +and displays it in a buffer and now this + +0:05:46.080,0:05:50.000 +postback list + +0:05:47.280,0:05:51.280 +is interpreted in a different way this + +0:05:50.000,0:05:54.400 +thing is interpreted + +0:05:51.280,0:05:54.800 +as a as a number of a page and a max + +0:05:54.400,0:05:57.520 +goes + +0:05:54.800,0:05:58.240 +to page three by counting form feeds in + +0:05:57.520,0:06:01.440 +the + +0:05:58.240,0:06:03.039 +converted version of the pdf and then it + +0:06:01.440,0:06:06.319 +searches for this string + +0:06:03.039,0:06:08.479 +and in this three so let's execute this + +0:06:06.319,0:06:10.800 +to see what happens + +0:06:08.479,0:06:13.280 +here it is i opened the same page as + +0:06:10.800,0:06:13.280 +before + +0:06:14.800,0:06:20.720 +it starts with lecture one so + +0:06:18.400,0:06:24.720 +the other hyperlink searched for this + +0:06:20.720,0:06:24.720 +string and for this string here + +0:06:25.520,0:06:30.400 +uh and this thing here is a hyperlink to + +0:06:28.160,0:06:32.720 +video + +0:06:30.400,0:06:34.560 +and when i executed it's going to open + +0:06:32.720,0:06:37.759 +this video here + +0:06:34.560,0:06:41.199 +at this time this time stamp let's see + +0:06:37.759,0:06:46.840 +one two three one + +0:06:41.199,0:06:49.440 +two three that's the way to do + +0:06:46.840,0:06:52.560 +it + +0:06:49.440,0:06:53.680 +and also some hyperlinks that that i + +0:06:52.560,0:06:56.479 +defined + +0:06:53.680,0:06:58.160 +uh they don't work like like usual + +0:06:56.479,0:07:01.440 +hyperlinks they work more + +0:06:58.160,0:07:05.759 +like browser buttons + +0:07:01.440,0:07:05.759 +these buttons that appear in web pages + +0:07:06.240,0:07:11.360 +in the sense that these buttons usually + +0:07:09.120,0:07:13.280 +don't open a new page they usually + +0:07:11.360,0:07:14.960 +just do something to change the current + +0:07:13.280,0:07:18.160 +page + +0:07:14.960,0:07:18.880 +if i execute this the action of this + +0:07:18.160,0:07:22.240 +function + +0:07:18.880,0:07:24.800 +eek is to uh + +0:07:22.240,0:07:25.919 +it interprets this string as a series of + +0:07:24.800,0:07:28.840 +keys and it + +0:07:25.919,0:07:30.319 +acts as if the user had typed all these + +0:07:28.840,0:07:33.680 +keys so + +0:07:30.319,0:07:34.400 +if executed i get a hello in the next + +0:07:33.680,0:07:36.639 +line + +0:07:34.400,0:07:39.440 +if executed again i get another hello + +0:07:36.639,0:07:44.319 +another hello hello hello etc etc + +0:07:39.440,0:07:47.840 +let me undo this mess oops + +0:07:44.319,0:07:51.440 +and here is another kind of button + +0:07:47.840,0:07:54.879 +that defines a new function if i execute + +0:07:51.440,0:07:55.759 +this sex here at this moment though is + +0:07:54.879,0:07:57.919 +not defined + +0:07:55.759,0:08:00.000 +and if i execute this mx is going to + +0:07:57.919,0:08:03.599 +show me a message saying + +0:08:00.000,0:08:05.840 +uh symbols function cell is not defined + +0:08:03.599,0:08:09.520 +something like this + +0:08:05.840,0:08:12.960 +but if i execute the defund + +0:08:09.520,0:08:16.479 +this the action of this function o here + +0:08:12.960,0:08:18.960 +is to run this which opens a certain + +0:08:16.479,0:08:21.840 +directory + +0:08:18.960,0:08:23.039 +let me go back and here is another + +0:08:21.840,0:08:25.840 +button that defines + +0:08:23.039,0:08:26.479 +several functions at the same time if i + +0:08:25.840,0:08:28.879 +execute + +0:08:26.479,0:08:28.879 +this + +0:08:32.320,0:08:36.719 +note that the the result of executing + +0:08:35.599,0:08:38.640 +this expression + +0:08:36.719,0:08:40.080 +is the name of one of the functions that + +0:08:38.640,0:08:42.800 +it defined + +0:08:40.080,0:08:43.360 +that is this one here and let me explain + +0:08:42.800,0:08:46.959 +the + +0:08:43.360,0:08:48.800 +these examples uh one of the functions + +0:08:46.959,0:08:51.839 +that this thing here defined + +0:08:48.800,0:08:54.640 +is called find or git file where + +0:08:51.839,0:08:55.040 +this or gate in the middle of its name + +0:08:54.640,0:08:59.600 +is + +0:08:55.040,0:09:02.640 +exactly this first argument to code cd + +0:08:59.600,0:09:03.120 +and the action of running find or get + +0:09:02.640,0:09:06.399 +file + +0:09:03.120,0:09:09.680 +on a string like this is that + +0:09:06.399,0:09:13.360 +find or get file takes the string + +0:09:09.680,0:09:15.600 +and prepends this string to it + +0:09:13.360,0:09:17.920 +this one here which is the second + +0:09:15.600,0:09:21.760 +argument to called cd + +0:09:17.920,0:09:25.600 +and then it executes find flying + +0:09:21.760,0:09:25.600 +on the result which is this one + +0:09:25.680,0:09:28.800 +and fine flying is my variant of find + +0:09:28.320,0:09:32.080 +file + +0:09:28.800,0:09:36.880 +that supports both spec lists + +0:09:32.080,0:09:39.600 +and this function here that i'm + +0:09:36.880,0:09:41.200 +referring to as a button it also defines + +0:09:39.600,0:09:44.880 +a function called + +0:09:41.200,0:09:46.080 +find audit node here where the or gate + +0:09:44.880,0:09:50.320 +is the same string + +0:09:46.080,0:09:54.160 +as here and this function opens a node + +0:09:50.320,0:09:57.920 +of of an info manual this one + +0:09:54.160,0:10:00.080 +this text here opens this node in the + +0:09:57.920,0:10:03.519 +org manual + +0:10:00.080,0:10:06.800 +it is equivalent to this text here + +0:10:03.519,0:10:08.720 +so in the passage from this line to this + +0:10:06.800,0:10:11.920 +line we prepended + +0:10:08.720,0:10:15.040 +to the node name the name of the manual + +0:10:11.920,0:10:18.160 +here and find node is my variant + +0:10:15.040,0:10:20.399 +of this standard mx function here + +0:10:18.160,0:10:23.200 +but find node also supports post + +0:10:20.399,0:10:23.200 +backlists + +0:10:23.519,0:10:28.640 +eevee also defines some functions that + +0:10:26.640,0:10:30.800 +define shorter hyperlinks to pdfs and + +0:10:28.640,0:10:32.880 +videos + +0:10:30.800,0:10:34.720 +remember that this thing here is a + +0:10:32.880,0:10:37.120 +shorter hyperlink to a + +0:10:34.720,0:10:39.040 +to a file and this thing here is a + +0:10:37.120,0:10:43.200 +shorter hyperlink to a node and + +0:10:39.040,0:10:46.079 +in an mx menu in an info manual + +0:10:43.200,0:10:47.279 +uh if we run this thing here this code + +0:10:46.079,0:10:50.240 +pdf page + +0:10:47.279,0:10:52.880 +this acts like a button that defines a + +0:10:50.240,0:10:56.399 +certain function + +0:10:52.880,0:10:59.040 +and this string this other sex + +0:10:56.399,0:11:00.240 +here defines another function the first + +0:10:59.040,0:11:03.040 +one defines + +0:11:00.240,0:11:05.360 +the function find funcspivac page and + +0:11:03.040,0:11:09.279 +the second one defines the function find + +0:11:05.360,0:11:12.240 +from text when we run the + +0:11:09.279,0:11:13.440 +file when we run findfoxpivotpage it + +0:11:12.240,0:11:17.600 +opens + +0:11:13.440,0:11:20.640 +this pdf here the name is + +0:11:17.600,0:11:23.839 +quite long uh + +0:11:20.640,0:11:26.079 +this example opens this pdf at page 8 + +0:11:23.839,0:11:28.000 +and searches for the string contents + +0:11:26.079,0:11:31.279 +oops sorry in this case + +0:11:28.000,0:11:33.519 +in this case it just ignores this string + +0:11:31.279,0:11:37.360 +here it only considers + +0:11:33.519,0:11:42.640 +the number of the page let's try + +0:11:37.360,0:11:45.200 +ah we got + +0:11:42.640,0:11:46.880 +here it is uh the contents of a book + +0:11:45.200,0:11:50.800 +that is freely + +0:11:46.880,0:11:51.760 +available uh here is another page of the + +0:11:50.800,0:11:55.040 +book + +0:11:51.760,0:11:55.519 +and if we execute the this happening + +0:11:55.040,0:11:58.399 +here + +0:11:55.519,0:11:59.920 +find funk's pivot text it converts the + +0:11:58.399,0:12:03.040 +pdf to text + +0:11:59.920,0:12:05.040 +and it searches for the page eight + +0:12:03.040,0:12:08.079 +in it and then for the string this + +0:12:05.040,0:12:11.839 +string here in page eight + +0:12:08.079,0:12:11.839 +it takes a few seconds + +0:12:12.240,0:12:20.320 +here it is so this is the + +0:12:16.160,0:12:25.040 +ascii version of this contents page + +0:12:20.320,0:12:28.800 +here uh note that this block here + +0:12:25.040,0:12:31.680 +is a kind of an index to that book + +0:12:28.800,0:12:33.600 +uh i have the full index somewhere but + +0:12:31.680,0:12:34.959 +it's very long so i just copied a few + +0:12:33.600,0:12:38.959 +lines here + +0:12:34.959,0:12:42.160 +uh so this is a link to the to set + +0:12:38.959,0:12:45.360 +section one chapter one this is the + +0:12:42.160,0:12:48.959 +section 1.1 + +0:12:45.360,0:12:53.839 +section 1.1.1 and so on + +0:12:48.959,0:12:53.839 +and here is a link to the index + +0:12:54.000,0:13:02.800 +and here is a part of my index + +0:12:58.079,0:13:03.279 +of positions in the video that we just + +0:13:02.800,0:13:05.760 +saw + +0:13:03.279,0:13:07.360 +that i think that are especially + +0:13:05.760,0:13:10.639 +relevant + +0:13:07.360,0:13:12.399 +uh so this i believe + +0:13:10.639,0:13:14.160 +hyperlink is a kind of a button that + +0:13:12.399,0:13:18.560 +defines this function here + +0:13:14.160,0:13:18.560 +find punch and punch into the video + +0:13:18.839,0:13:21.839 +uh + +0:13:27.600,0:13:33.360 +and we can also use this for video + +0:13:31.440,0:13:37.200 +tutorials for example + +0:13:33.360,0:13:40.639 +this is a very good tutorial on on magic + +0:13:37.200,0:13:40.639 +if we execute this + +0:13:40.880,0:13:44.800 +then these functions are going to be + +0:13:42.560,0:13:48.399 +defined and these functions open + +0:13:44.800,0:13:50.079 +this tutorial on magic + +0:13:48.399,0:13:51.839 +these are some of the positions in the + +0:13:50.079,0:13:53.920 +tutorial that i found especially + +0:13:51.839,0:13:55.600 +especially relevant this is a very dense + +0:13:53.920,0:13:56.480 +tutorial i had to take notes of + +0:13:55.600,0:13:59.040 +everything + +0:13:56.480,0:14:00.800 +and i had to watch everything things + +0:13:59.040,0:14:03.440 +several times + +0:14:00.800,0:14:06.480 +and for example this is a link to the + +0:14:03.440,0:14:09.600 +position in the tutorial that explains + +0:14:06.480,0:14:12.880 +uh how in space + +0:14:09.600,0:14:17.600 +space max magic magic + +0:14:12.880,0:14:20.480 +interprets space gs magic status + +0:14:17.600,0:14:22.320 +let's see beginners space gs to initiate + +0:14:20.480,0:14:25.600 +magic's git status + +0:14:22.320,0:14:28.800 +uh you can also do that's it + +0:14:25.600,0:14:32.160 +and here are some examples that i + +0:14:28.800,0:14:34.240 +took from somewhere else the video + +0:14:32.160,0:14:38.800 +tutorials from + +0:14:34.240,0:14:38.800 +ralph koenig about org mode + +0:14:43.519,0:14:47.440 +now let me show how the functions that + +0:14:45.519,0:14:48.720 +define this router hyperlinks are + +0:14:47.440,0:14:51.199 +implemented + +0:14:48.720,0:14:52.480 +the standard ways in max to define + +0:14:51.199,0:14:55.760 +functions that define + +0:14:52.480,0:14:58.320 +other functions would be with macros uh + +0:14:55.760,0:14:59.040 +let's see an example this is a standard + +0:14:58.320,0:15:01.540 +function that + +0:14:59.040,0:15:02.959 +defines new functions + +0:15:01.540,0:15:06.959 +[Music] + +0:15:02.959,0:15:09.040 +and if we execute it one of the res + +0:15:06.959,0:15:10.160 +its result is the last function that it + +0:15:09.040,0:15:13.839 +defined which is + +0:15:10.160,0:15:13.839 +e-grief which is here + +0:15:13.920,0:15:19.360 +it's implemented as a macro we can + +0:15:16.959,0:15:20.880 +look at the result of macro expand which + +0:15:19.360,0:15:23.519 +is going to show + +0:15:20.880,0:15:25.519 +show us the result of of this of the + +0:15:23.519,0:15:28.000 +expansion of this + +0:15:25.519,0:15:28.959 +instead of expanding and executing it + +0:15:28.000,0:15:33.199 +just + +0:15:28.959,0:15:36.000 +expands and shows us the result + +0:15:33.199,0:15:37.600 +here the result is a bit messy is too + +0:15:36.000,0:15:40.959 +big for + +0:15:37.600,0:15:44.240 +humans to understand but we can run + +0:15:40.959,0:15:47.519 +this or this text here that takes that + +0:15:44.240,0:15:50.959 +that result and pretty prints it + +0:15:47.519,0:15:54.000 +so this is the pretty printed version of + +0:15:50.959,0:15:57.600 +uh this macro here + +0:15:54.000,0:16:01.120 +we can see that it defines + +0:15:57.600,0:16:04.399 +several functions here + +0:16:01.120,0:16:04.399 +for example this one + +0:16:06.399,0:16:09.920 +and this just as a curiosity is a link + +0:16:09.360,0:16:13.839 +to + +0:16:09.920,0:16:16.880 +the definition of cld struct + +0:16:13.839,0:16:19.199 +and note that the code is huge uh + +0:16:16.880,0:16:20.079 +well it's very well commented but it's + +0:16:19.199,0:16:23.759 +it has + +0:16:20.079,0:16:26.959 +lots of special cases it has uh + +0:16:23.759,0:16:27.920 +it supports lots of constructions and so + +0:16:26.959,0:16:30.639 +it's huge and + +0:16:27.920,0:16:33.360 +it's very difficult to understand i mean + +0:16:30.639,0:16:35.040 +i found it very difficult to understand + +0:16:33.360,0:16:37.759 +and here's a link to document the + +0:16:35.040,0:16:42.000 +documentation of cld struct + +0:16:37.759,0:16:46.000 +here in the manual for + +0:16:42.000,0:16:50.480 +cl which is a kind of support for some + +0:16:46.000,0:16:53.600 +features of common lisp in the max + +0:16:50.480,0:16:54.639 +so let's compare this standard way of + +0:16:53.600,0:16:56.560 +defining + +0:16:54.639,0:16:58.320 +functions that define new functions + +0:16:56.560,0:17:01.680 +which is with macros + +0:16:58.320,0:17:04.160 +with this i'm going to use a slogan + +0:17:01.680,0:17:06.319 +repeatedly the slogan is i am a very bad + +0:17:04.160,0:17:08.880 +programmer + +0:17:06.319,0:17:10.640 +i'm a very bad programmer so when i was + +0:17:08.880,0:17:12.240 +trying to create functions that would + +0:17:10.640,0:17:14.480 +define new functions + +0:17:12.240,0:17:16.400 +i found it easier to generally generate + +0:17:14.480,0:17:20.559 +this code as text + +0:17:16.400,0:17:23.199 +and then run read and eval in it + +0:17:20.559,0:17:24.640 +the code cd that we saw in the previous + +0:17:23.199,0:17:28.079 +section + +0:17:24.640,0:17:29.039 +we can see the the code that it produces + +0:17:28.079,0:17:31.039 +by + +0:17:29.039,0:17:33.280 +making a copy of this line and + +0:17:31.039,0:17:34.480 +prepending this string here to the name + +0:17:33.280,0:17:36.720 +of the function + +0:17:34.480,0:17:38.400 +so instead of running code cd we run + +0:17:36.720,0:17:41.280 +find code cd + +0:17:38.400,0:17:44.400 +and it creates a new temporary buffer + +0:17:41.280,0:17:47.760 +with the code that + +0:17:44.400,0:17:50.320 +code cd would execute + +0:17:47.760,0:17:53.919 +so it's a series of the fonts and a few + +0:17:50.320,0:17:53.919 +set cues and so on + +0:17:54.080,0:17:59.120 +and this thing is implemented mostly as + +0:17:57.600,0:18:02.160 +a template + +0:17:59.120,0:18:04.160 +uh the lola the + +0:18:02.160,0:18:06.240 +there's an inner function called ee + +0:18:04.160,0:18:08.799 +called cd base that receives just + +0:18:06.240,0:18:10.640 +these two arguments and it says + +0:18:08.799,0:18:14.320 +essentially just runs the function + +0:18:10.640,0:18:16.480 +e template zero on the string here and + +0:18:14.320,0:18:18.559 +the things between curly braces are + +0:18:16.480,0:18:22.559 +substituted by the values + +0:18:18.559,0:18:22.559 +of these arguments here + +0:18:23.600,0:18:28.480 +there's one part of the tutorial here + +0:18:25.919,0:18:31.039 +that explains all these things + +0:18:28.480,0:18:32.559 +uh except for the rationale for some + +0:18:31.039,0:18:35.360 +design decisions + +0:18:32.559,0:18:37.280 +and those design decisions are one of + +0:18:35.360,0:18:37.760 +the many motivations for this talk but + +0:18:37.280,0:18:39.679 +um + +0:18:37.760,0:18:42.640 +we are i'm only going to explain these + +0:18:39.679,0:18:46.799 +things in detail at the end + +0:18:42.640,0:18:46.799 +which is kind of so on + +0:18:48.480,0:18:51.600 +in the beginning i said that the three + +0:18:50.320,0:18:56.000 +main keys of av + +0:18:51.600,0:19:00.080 +are meta e meta k and meta j + +0:18:56.000,0:19:01.520 +let's see now what met what meta j does + +0:19:00.080,0:19:04.640 +uh but i need to start with some + +0:19:01.520,0:19:06.559 +motivation uh the motivation is that we + +0:19:04.640,0:19:08.240 +can define commands with very short + +0:19:06.559,0:19:10.160 +names and actually i became kind of + +0:19:08.240,0:19:13.200 +addicted to that + +0:19:10.160,0:19:15.600 +this is an example of the fund that + +0:19:13.200,0:19:18.000 +defines a comment with a very short name + +0:19:15.600,0:19:21.200 +its name is just one letter e + +0:19:18.000,0:19:21.520 +and i can invoke you invoke it with meta + +0:19:21.200,0:19:24.720 +x + +0:19:21.520,0:19:27.360 +e if i type meta xp + +0:19:24.720,0:19:30.000 +now it opens a latex file that i'm + +0:19:27.360,0:19:30.000 +working on + +0:19:31.130,0:19:35.200 +[Music] + +0:19:32.559,0:19:37.120 +and i create most of my latex files + +0:19:35.200,0:19:39.200 +using + +0:19:37.120,0:19:40.559 +template template-based functions like + +0:19:39.200,0:19:43.760 +the the + +0:19:40.559,0:19:46.559 +implementation of code cd above and + +0:19:43.760,0:19:49.280 +this template-based functions create + +0:19:46.559,0:19:51.280 +files with extension.tag + +0:19:49.280,0:19:53.919 +that start with a series of the fonts + +0:19:51.280,0:19:56.240 +and comments for example + +0:19:53.919,0:19:58.320 +let's look at this example here if i + +0:19:56.240,0:19:59.440 +execute find the attack links with this + +0:19:58.320,0:20:02.159 +argument + +0:19:59.440,0:20:03.440 +uh it's going it's going to do several + +0:20:02.159,0:20:06.880 +things for creating a + +0:20:03.440,0:20:08.320 +file called slash tmp slash forward + +0:20:06.880,0:20:11.200 +attack + +0:20:08.320,0:20:12.400 +and the header of that file is going to + +0:20:11.200,0:20:16.080 +be this + +0:20:12.400,0:20:19.280 +which starts with two and with three + +0:20:16.080,0:20:21.919 +the fonts with functions with very short + +0:20:19.280,0:20:26.240 +names and comments + +0:20:21.919,0:20:26.240 +let's compare with the situation here + +0:20:27.520,0:20:34.640 +in my file 2020 favorite conventions.tag + +0:20:32.799,0:20:37.039 +i have this header here in which i + +0:20:34.640,0:20:39.360 +define six functions with very short + +0:20:37.039,0:20:41.919 +names + +0:20:39.360,0:20:44.799 +and in this case here that is even + +0:20:41.919,0:20:48.000 +explained in the tutorial + +0:20:44.799,0:20:51.520 +this we have mnemonics for + +0:20:48.000,0:20:54.799 +these short names here and c is compile + +0:20:51.520,0:20:57.760 +d is display i mean display the pdf + +0:20:54.799,0:20:58.159 +and e is added in the sense of make a + +0:20:57.760,0:21:02.320 +max + +0:20:58.159,0:21:05.039 +visit that file + +0:21:02.320,0:21:06.480 +okay now i can explain what is meta j + +0:21:05.039,0:21:08.880 +itself + +0:21:06.480,0:21:09.600 +uh we just saw comments with very short + +0:21:08.880,0:21:12.320 +names + +0:21:09.600,0:21:14.840 +and the idea is behind meta j is that we + +0:21:12.320,0:21:16.480 +can define comments with very short + +0:21:14.840,0:21:19.679 +numbers + +0:21:16.480,0:21:22.559 +let me explain this uh + +0:21:19.679,0:21:23.039 +the short explanation for what meta j + +0:21:22.559,0:21:25.360 +does + +0:21:23.039,0:21:27.039 +is that it jumps to set certain + +0:21:25.360,0:21:29.760 +predefined places + +0:21:27.039,0:21:30.799 +in particular a meta j without a numeric + +0:21:29.760,0:21:33.280 +argument + +0:21:30.799,0:21:34.080 +takes us to a buffer with with the basic + +0:21:33.280,0:21:37.679 +help + +0:21:34.080,0:21:39.760 +and a list of the current age of targets + +0:21:37.679,0:21:41.520 +and this is something that is a bit + +0:21:39.760,0:21:44.559 +simpler to understand + +0:21:41.520,0:21:47.919 +if we type meta five meta j + +0:21:44.559,0:21:51.120 +then meta j runs this sex + +0:21:47.919,0:21:55.440 +here that is associated to + +0:21:51.120,0:21:59.039 +the argument five i say that the target + +0:21:55.440,0:22:01.520 +for the argument five is this one + +0:21:59.039,0:22:03.760 +and if the argument is true then the + +0:22:01.520,0:22:07.039 +target associated to the to the true + +0:22:03.760,0:22:09.600 +is this sex here that opens + +0:22:07.039,0:22:10.240 +well this one opens the main tutorial vv + +0:22:09.600,0:22:13.679 +and this one + +0:22:10.240,0:22:15.679 +opens another tutorial + +0:22:13.679,0:22:20.480 +this is a link to one of the tutorials + +0:22:15.679,0:22:22.559 +of ev to the part that explains meta j + +0:22:20.480,0:22:24.559 +i've copied the the main part of the + +0:22:22.559,0:22:28.159 +text here + +0:22:24.559,0:22:31.360 +the header the header that meta j shows + +0:22:28.159,0:22:33.919 +let me show it very quickly here + +0:22:31.360,0:22:36.320 +here is their header and here is their + +0:22:33.919,0:22:39.039 +rest + +0:22:36.320,0:22:40.000 +the header is very beginner friendly and + +0:22:39.039,0:22:42.159 +if you're a beginner + +0:22:40.000,0:22:44.559 +who only knows how to use meta e to + +0:22:42.159,0:22:46.799 +execute and met + +0:22:44.559,0:22:48.240 +this should be okay and meta k to go + +0:22:46.799,0:22:52.320 +back + +0:22:48.240,0:22:55.840 +then you can and should use that header + +0:22:52.320,0:22:55.840 +i mean this header here + +0:22:56.720,0:23:00.799 +as your main starting point and every + +0:22:59.360,0:23:03.679 +time that you feel lost + +0:23:00.799,0:23:04.799 +you can type meta j and to go back to + +0:23:03.679,0:23:07.039 +that header + +0:23:04.799,0:23:08.000 +and you can use its links to navigate to + +0:23:07.039,0:23:11.360 +the documentation + +0:23:08.000,0:23:14.799 +for max nav let me explain that + +0:23:11.360,0:23:15.679 +uh this header here has several ellis + +0:23:14.799,0:23:19.039 +hyperlinks + +0:23:15.679,0:23:22.400 +one here one here + +0:23:19.039,0:23:25.760 +one here one here and so on + +0:23:22.400,0:23:29.280 +uh these ones are links to the + +0:23:25.760,0:23:30.880 +to the intros which are the tutorials + +0:23:29.280,0:23:32.480 +find if you quick enter in the main + +0:23:30.880,0:23:35.760 +tutorial and find ev + +0:23:32.480,0:23:36.720 +keys intro is a kind of tutorial that is + +0:23:35.760,0:23:39.520 +an index of + +0:23:36.720,0:23:39.520 +the main keys + +0:23:40.000,0:23:43.279 +and after that we have an explanation of + +0:23:42.559,0:23:46.799 +what some + +0:23:43.279,0:23:50.240 +numeric prefixes do so if we type + +0:23:46.799,0:23:53.200 +met one method j the effect of that is + +0:23:50.240,0:23:54.640 +exactly the same as executing this and + +0:23:53.200,0:23:58.080 +we can execute this + +0:23:54.640,0:23:58.080 +with meta e also + +0:24:00.159,0:24:06.960 +meta tube meta j runs this sex and + +0:24:03.679,0:24:10.559 +i can also execute it with meta e + +0:24:06.960,0:24:14.240 +here it is it's this uh + +0:24:10.559,0:24:18.400 +intro this uh + +0:24:14.240,0:24:22.960 +sandbox tutorial and + +0:24:18.400,0:24:22.960 +here is another sandbox tutorial + +0:24:24.640,0:24:28.720 +let me go back and then the + +0:24:27.039,0:24:30.880 +documentation says that + +0:24:28.720,0:24:31.760 +that header the header that is beginner + +0:24:30.880,0:24:33.679 +friendly + +0:24:31.760,0:24:35.520 +is followed by a section that is very + +0:24:33.679,0:24:37.600 +beginner unfriendly + +0:24:35.520,0:24:40.240 +that contains a series of the fonts like + +0:24:37.600,0:24:40.240 +these ones + +0:24:40.400,0:24:44.640 +here the last line of the header is this + +0:24:43.440,0:24:46.720 +comment here + +0:24:44.640,0:24:48.559 +and then we have several defense like + +0:24:46.720,0:24:51.440 +this + +0:24:48.559,0:24:53.840 +let me explain how these things work + +0:24:51.440,0:24:57.360 +technically what happens when we type + +0:24:53.840,0:24:57.840 +meta j without any arguments is that it + +0:24:57.360,0:25:00.960 +runs + +0:24:57.840,0:25:04.640 +eu jump with argument neil and then + +0:25:00.960,0:25:06.480 +this runs 5 e jumps + +0:25:04.640,0:25:08.000 +when i run meta j with a numeric + +0:25:06.480,0:25:11.120 +argument for example + +0:25:08.000,0:25:14.400 +with argument 5 it runs a jump + +0:25:11.120,0:25:17.679 +5 and e jump five + +0:25:14.400,0:25:20.400 +uh concatenates this five one + +0:25:17.679,0:25:21.679 +to make a name of a function this + +0:25:20.400,0:25:24.320 +function here + +0:25:21.679,0:25:24.720 +and it executes this function e jump + +0:25:24.320,0:25:28.880 +five + +0:25:24.720,0:25:31.919 +you jump uh dash five + +0:25:28.880,0:25:35.520 +and eu jump dash five is + +0:25:31.919,0:25:39.360 +executes find ev equity intro + +0:25:35.520,0:25:41.440 +if i execute just meta j + +0:25:39.360,0:25:43.919 +the section that shows the current age + +0:25:41.440,0:25:47.120 +on targets + +0:25:43.919,0:25:48.159 +has a line for e job five this is that + +0:25:47.120,0:25:52.159 +is exactly the + +0:25:48.159,0:25:52.159 +thing that i was explaining before + +0:25:52.400,0:25:59.520 +so we can use meta j to navigate the + +0:25:54.840,0:26:03.440 +tutorials and we can copy the links + +0:25:59.520,0:26:06.799 +sorry we can copy links to the to + +0:26:03.440,0:26:06.799 +tutorials to our notes + +0:26:07.919,0:26:14.880 +oh sorry this has some typos + +0:26:11.840,0:26:18.080 +for example if i execute this + +0:26:14.880,0:26:20.640 +i go to a section of this tutorial here + +0:26:18.080,0:26:24.320 +that explains the main keys of ev + +0:26:20.640,0:26:26.240 +and these things are hyperlinks i can + +0:26:24.320,0:26:27.440 +mark a hyperlink like this it is just + +0:26:26.240,0:26:30.559 +plain text and i + +0:26:27.440,0:26:31.760 +can copy it to my notes and the idea is + +0:26:30.559,0:26:33.520 +that every time + +0:26:31.760,0:26:35.520 +every time that i find something that is + +0:26:33.520,0:26:36.240 +interesting i can create a hyperlink to + +0:26:35.520,0:26:38.720 +it + +0:26:36.240,0:26:40.799 +and i can put these links in my notes so + +0:26:38.720,0:26:42.960 +i can navigate back + +0:26:40.799,0:26:45.360 +to all the interesting positions very + +0:26:42.960,0:26:45.360 +quickly + +0:26:48.799,0:26:54.080 +okay next feature if we type meta + +0:26:51.760,0:26:57.039 +uppercase j + +0:26:54.080,0:26:57.039 +uh then + +0:26:57.600,0:27:03.679 +this this is a function that transforms + +0:27:00.080,0:27:06.080 +the current line in a certain way + +0:27:03.679,0:27:07.360 +let me give an example let me isolate + +0:27:06.080,0:27:09.919 +this and let me create + +0:27:07.360,0:27:11.039 +duplicate this line to to make clear + +0:27:09.919,0:27:14.240 +what happens + +0:27:11.039,0:27:16.880 +if i type meta uppercase j here + +0:27:14.240,0:27:17.440 +this line here becomes the fund for a + +0:27:16.880,0:27:21.200 +jump + +0:27:17.440,0:27:24.799 +6 and the target of this e-jump + +0:27:21.200,0:27:28.399 +is exactly this sex here + +0:27:24.799,0:27:28.399 +let me undo this mess + +0:27:28.559,0:27:32.840 +and if the first word in the line is not + +0:27:31.360,0:27:36.240 +a number for example + +0:27:32.840,0:27:39.039 +here let me do the same thing + +0:27:36.240,0:27:41.200 +duplicate the line and type meta + +0:27:39.039,0:27:44.240 +uppercase j + +0:27:41.200,0:27:45.600 +then mat uppercase j converts that to a + +0:27:44.240,0:27:49.440 +defund that defines + +0:27:45.600,0:27:52.720 +a function with a very short name + +0:27:49.440,0:27:56.720 +and this function with a very short name + +0:27:52.720,0:27:59.360 +opens this file here in the directory + +0:27:56.720,0:28:01.360 +with the copy of the the git repository + +0:27:59.360,0:28:04.880 +for org mode + +0:28:01.360,0:28:04.880 +let me undo the mass again + +0:28:05.360,0:28:07.760 +oops + +0:28:09.120,0:28:11.679 +that's it + +0:28:14.640,0:28:21.279 +meta uppercase j is a + +0:28:17.760,0:28:24.559 +particular case of of something that + +0:28:21.279,0:28:25.279 +i use a lot in eevee i have if he has + +0:28:24.559,0:28:28.799 +lots of + +0:28:25.279,0:28:31.780 +comments that sorry key sequences + +0:28:28.799,0:28:33.200 +that are like meta uppercase letter and + +0:28:31.780,0:28:35.279 +[Music] + +0:28:33.200,0:28:37.279 +almost all of them operate on the + +0:28:35.279,0:28:38.880 +current line and transform the current + +0:28:37.279,0:28:42.000 +line in certain way + +0:28:38.880,0:28:45.360 +for example this is a file name + +0:28:42.000,0:28:48.640 +and if i type meta uppercase f here + +0:28:45.360,0:28:50.000 +it becomes a link to that file this is + +0:28:48.640,0:28:53.600 +the name of a month page + +0:28:50.000,0:28:55.760 +and if i type meta uppercase m here + +0:28:53.600,0:28:58.080 +it converts that to the link to a month + +0:28:55.760,0:29:01.679 +page and this is a shell command + +0:28:58.080,0:29:04.960 +and if i type meta uppercase s here + +0:29:01.679,0:29:08.720 +it converts that to a link to a + +0:29:04.960,0:29:11.919 +to find fan shell + +0:29:08.720,0:29:12.960 +and until a few years ago these + +0:29:11.919,0:29:16.159 +functions + +0:29:12.960,0:29:18.080 +with matter uppercase letter were half + +0:29:16.159,0:29:18.880 +of my main ways of creating sex + +0:29:18.080,0:29:21.039 +hyperlinks + +0:29:18.880,0:29:22.399 +with few key strokes in the beginning of + +0:29:21.039,0:29:25.600 +course i had to create my + +0:29:22.399,0:29:28.640 +sex pipelines by typing each character + +0:29:25.600,0:29:31.520 +but uh after some time and decided that + +0:29:28.640,0:29:34.559 +i needed something more efficient + +0:29:31.520,0:29:34.960 +so this is end of part one of the two of + +0:29:34.559,0:29:37.760 +the + +0:29:34.960,0:29:37.760 +presentation + +0:29:38.480,0:29:41.760 +so this is part two of the presentation + +0:29:40.640,0:29:44.320 +and the main theme + +0:29:41.760,0:29:46.320 +here is the standard describe key + +0:29:44.320,0:29:49.200 +function that comes with the max + +0:29:46.320,0:29:50.960 +and my variant of it the thing is that + +0:29:49.200,0:29:53.120 +the standard described key in max + +0:29:50.960,0:29:55.600 +is user friendly but it is hacker + +0:29:53.120,0:29:58.559 +unfriendly well i felt so + +0:29:55.600,0:30:00.799 +and when i tried to complement it by by + +0:29:58.559,0:30:03.120 +writing a hacker friendly version of it + +0:30:00.799,0:30:03.919 +that produced the sex hyperlinks that i + +0:30:03.120,0:30:05.440 +needed + +0:30:03.919,0:30:07.039 +i got something that i found really + +0:30:05.440,0:30:09.679 +lovely and + +0:30:07.039,0:30:12.480 +several of the main designs design + +0:30:09.679,0:30:14.320 +decisions of eev can be seen there + +0:30:12.480,0:30:15.520 +but when i showed my variants to other + +0:30:14.320,0:30:17.760 +people they hated it + +0:30:15.520,0:30:19.360 +they felt that it was totally against + +0:30:17.760,0:30:23.440 +their notions of + +0:30:19.360,0:30:25.760 +user friendliness + +0:30:23.440,0:30:26.799 +okay so let's see the standard describe + +0:30:25.760,0:30:30.159 +key if i run + +0:30:26.799,0:30:32.399 +this hyperlink here i get + +0:30:30.159,0:30:34.399 +this the result of running the scribe + +0:30:32.399,0:30:36.399 +key on the key down + +0:30:34.399,0:30:38.080 +and this is a big buffer with some + +0:30:36.399,0:30:41.360 +things in italics + +0:30:38.080,0:30:43.120 +and some hyperlinks here these + +0:30:41.360,0:30:43.679 +hyperlinks are standard in the sense + +0:30:43.120,0:30:46.240 +that + +0:30:43.679,0:30:47.760 +the targets are not visible and they are + +0:30:46.240,0:30:50.799 +implemented using + +0:30:47.760,0:30:51.200 +buttons in a max lisp this section of + +0:30:50.799,0:30:53.919 +the + +0:30:51.200,0:30:56.240 +mx list manual describes how buttons + +0:30:53.919,0:30:56.240 +work + +0:30:56.799,0:31:03.440 +and the the source code is + +0:31:00.640,0:31:04.240 +quite difficult i mean when i was + +0:31:03.440,0:31:06.559 +starting to + +0:31:04.240,0:31:07.600 +to try to decipher this when i was a + +0:31:06.559,0:31:11.200 +beginner + +0:31:07.600,0:31:12.320 +using max 19.34 i felt that this + +0:31:11.200,0:31:15.519 +described key was + +0:31:12.320,0:31:20.080 +very difficult to understand uh + +0:31:15.519,0:31:22.640 +and i felt that the the designers the + +0:31:20.080,0:31:23.679 +the people who wrote it were sacrificing + +0:31:22.640,0:31:26.159 +too much of the + +0:31:23.679,0:31:30.000 +hacker friendliness that i was expecting + +0:31:26.159,0:31:30.000 +from it to make it beginner friendly + +0:31:31.279,0:31:34.799 +let me explain what are the the problems + +0:31:33.600,0:31:36.559 +with the standard + +0:31:34.799,0:31:38.640 +the describe key if we think that + +0:31:36.559,0:31:41.600 +hyperlinks are things like this + +0:31:38.640,0:31:43.600 +with the target and the text then in the + +0:31:41.600,0:31:47.120 +button hyperlinks of describe key + +0:31:43.600,0:31:49.120 +this three bad things happen first + +0:31:47.120,0:31:51.200 +it is hard to extract the target from + +0:31:49.120,0:31:52.000 +the hyperlink second it is hard to + +0:31:51.200,0:31:54.480 +recreate + +0:31:52.000,0:31:55.440 +a list of code that would go to that + +0:31:54.480,0:31:57.519 +target + +0:31:55.440,0:31:59.840 +and third it is hard to copy the full + +0:31:57.519,0:32:00.640 +hyperlink including the targets to other + +0:31:59.840,0:32:04.399 +buffers + +0:32:00.640,0:32:04.399 +i only knew how to copy the text + +0:32:04.960,0:32:09.039 +when i was trying to decipher what + +0:32:07.279,0:32:11.679 +described key was doing + +0:32:09.039,0:32:12.159 +i created lots of hyperlinks like this + +0:32:11.679,0:32:14.960 +to + +0:32:12.159,0:32:16.159 +inspect the text properties and things + +0:32:14.960,0:32:18.480 +like that + +0:32:16.159,0:32:20.000 +for example in the description of the + +0:32:18.480,0:32:23.600 +key down + +0:32:20.000,0:32:26.559 +here we have a button that points to + +0:32:23.600,0:32:26.559 +simple dotel + +0:32:26.799,0:32:31.600 +the text of that button is simple.l this + +0:32:29.679,0:32:34.320 +hyperlinks goes to the + +0:32:31.600,0:32:35.519 +to the middle of this button hyperlink + +0:32:34.320,0:32:39.120 +here + +0:32:35.519,0:32:41.919 +uh this hyperlink here + +0:32:39.120,0:32:43.279 +goes to the middle of the button of this + +0:32:41.919,0:32:46.240 +button hyperlink + +0:32:43.279,0:32:47.679 +and then inspects its text properties + +0:32:46.240,0:32:51.679 +and then goes to + +0:32:47.679,0:32:53.679 +this section here of the description + +0:32:51.679,0:32:56.159 +so this is a high level description of + +0:32:53.679,0:32:58.000 +the text properties + +0:32:56.159,0:33:00.000 +i mean the text properties that make it + +0:32:58.000,0:33:02.480 +a button and this is a + +0:33:00.000,0:33:04.320 +lower level description of the these + +0:33:02.480,0:33:08.000 +text properties + +0:33:04.320,0:33:11.440 +and the button that points to + +0:33:08.000,0:33:11.919 +forward line sorry the the button that + +0:33:11.440,0:33:14.399 +whose + +0:33:11.919,0:33:16.480 +text is forward line this one is + +0:33:14.399,0:33:19.039 +slightly different + +0:33:16.480,0:33:21.200 +this hyperlink here goes to the middle + +0:33:19.039,0:33:24.559 +of that button + +0:33:21.200,0:33:25.760 +and this hyperlink goes to the mid to + +0:33:24.559,0:33:28.559 +the middle of that button + +0:33:25.760,0:33:29.360 +inspects its text properties and go to + +0:33:28.559,0:33:32.559 +the section + +0:33:29.360,0:33:35.760 +of this button of this help + +0:33:32.559,0:33:36.399 +uh buffer here that describe the the + +0:33:35.760,0:33:39.120 +button + +0:33:36.399,0:33:41.679 +and the lower level view of the text + +0:33:39.120,0:33:45.519 +properties + +0:33:41.679,0:33:47.519 +so i started to with things like this + +0:33:45.519,0:33:50.159 +to understand what these buttons were + +0:33:47.519,0:33:50.960 +doing and i was able to figure out how + +0:33:50.159,0:33:53.120 +these things are + +0:33:50.960,0:33:55.519 +implemented and describe key and then + +0:33:53.120,0:33:57.760 +similar help functions in max + +0:33:55.519,0:34:00.000 +and i discovered that one of the main + +0:33:57.760,0:34:01.360 +lower level functions that a max used + +0:34:00.000,0:34:04.080 +for this + +0:34:01.360,0:34:05.279 +is a function called find function no + +0:34:04.080,0:34:08.240 +select + +0:34:05.279,0:34:09.929 +if i run find function no select on next + +0:34:08.240,0:34:11.200 +line + +0:34:09.929,0:34:14.240 +[Music] + +0:34:11.200,0:34:18.079 +it returns a pair + +0:34:14.240,0:34:20.560 +a cons made of a buffer and a position + +0:34:18.079,0:34:21.679 +so i created functions that would that + +0:34:20.560,0:34:24.320 +would + +0:34:21.679,0:34:25.119 +uh follow this that would open that + +0:34:24.320,0:34:28.320 +buffer + +0:34:25.119,0:34:29.679 +in that position and then this is a + +0:34:28.320,0:34:31.679 +postback list + +0:34:29.679,0:34:33.919 +so we could go to these positions and + +0:34:31.679,0:34:36.000 +then search for this string and another + +0:34:33.919,0:34:40.320 +string and another string and so on + +0:34:36.000,0:34:41.040 +so this goes to the definition of find a + +0:34:40.320,0:34:44.159 +function + +0:34:41.040,0:34:47.919 +and then to a to a string + +0:34:44.159,0:34:49.040 +after it and i use these things to + +0:34:47.919,0:34:51.839 +implement my own + +0:34:49.040,0:34:52.960 +functions that pointed to the same the + +0:34:51.839,0:34:55.440 +same targets + +0:34:52.960,0:34:57.679 +as the button hyperlinks and describe + +0:34:55.440,0:34:57.679 +key + +0:35:00.240,0:35:05.599 +again let me show the comparison this is + +0:35:03.200,0:35:10.480 +the standard describe key + +0:35:05.599,0:35:13.839 +here and this is my variant + +0:35:10.480,0:35:17.680 +uh it creates a buffer with links + +0:35:13.839,0:35:20.960 +with the list hyperlinks about this key + +0:35:17.680,0:35:22.960 +we get this so each one of these + +0:35:20.960,0:35:27.280 +functions is either a blank line + +0:35:22.960,0:35:27.280 +or a or an ellipse hyperlink + +0:35:28.720,0:35:32.880 +here is a slight variant of the of the + +0:35:31.760,0:35:35.920 +function + +0:35:32.880,0:35:38.079 +find e key links above in this variant + +0:35:35.920,0:35:39.280 +the argument is a string that has to be + +0:35:38.079,0:35:42.400 +processed by + +0:35:39.280,0:35:45.280 +read cbd macro to convert it to the + +0:35:42.400,0:35:48.160 +lower level format + +0:35:45.280,0:35:49.040 +and note that these functions here that + +0:35:48.160,0:35:51.440 +i wrote + +0:35:49.040,0:35:53.599 +they display temporary buffers with no + +0:35:51.440,0:35:57.359 +help at all + +0:35:53.599,0:35:58.560 +uh to be honest there's a link to a + +0:35:57.359,0:36:01.680 +tutorial here but + +0:35:58.560,0:36:03.200 +this is a recent edition so let's ignore + +0:36:01.680,0:36:06.640 +this + +0:36:03.200,0:36:08.320 +uh they they display temporary buffers + +0:36:06.640,0:36:09.520 +with no help at all just lots of + +0:36:08.320,0:36:11.599 +hyperlinks + +0:36:09.520,0:36:13.359 +and these hyperlinks can be they are + +0:36:11.599,0:36:15.040 +very hacker friendly in the sense that + +0:36:13.359,0:36:17.520 +they can be followed with + +0:36:15.040,0:36:19.920 +metae they can be copied to other + +0:36:17.520,0:36:23.680 +buffers because they are plain text + +0:36:19.920,0:36:26.240 +because they are just sex + +0:36:23.680,0:36:28.000 +and they can be inspected in the sense + +0:36:26.240,0:36:31.280 +that + +0:36:28.000,0:36:31.280 +for example here + +0:36:32.400,0:36:35.520 +we have a hyperlink to a function that + +0:36:34.079,0:36:37.599 +we + +0:36:35.520,0:36:39.200 +it may be difficult to figure out what + +0:36:37.599,0:36:42.320 +this function does + +0:36:39.200,0:36:45.839 +but we can go to that position and then + +0:36:42.320,0:36:48.240 +type ctrl h f to see the descript + +0:36:45.839,0:36:52.400 +description of this function + +0:36:48.240,0:36:53.890 +and here is a hyperlink to + +0:36:52.400,0:36:56.000 +the does that + +0:36:53.890,0:36:59.920 +[Music] + +0:36:56.000,0:36:59.920 +in my syntax say + +0:37:00.160,0:37:04.480 +and this list of hyperlinks were + +0:37:02.800,0:37:08.000 +generated by + +0:37:04.480,0:37:11.119 +this code here that just just uh + +0:37:08.000,0:37:14.320 +used a back quote to to generate + +0:37:11.119,0:37:14.320 +lists of sex + +0:37:14.640,0:37:21.040 +and i i felt that this function here + +0:37:18.240,0:37:22.160 +uh that just generated this list was + +0:37:21.040,0:37:24.960 +very easy to understand + +0:37:22.160,0:37:28.480 +and to modify so this was hacker + +0:37:24.960,0:37:31.599 +friendly in the way that i wanted + +0:37:28.480,0:37:34.079 +and so i started using this + +0:37:31.599,0:37:36.800 +and this idea of using buffers with sex + +0:37:34.079,0:37:38.720 +fiber links and no help violated + +0:37:36.800,0:37:40.079 +all the notions of user friendliness + +0:37:38.720,0:37:42.000 +that i knew so i was + +0:37:40.079,0:37:46.160 +exploring some something new at that + +0:37:42.000,0:37:49.359 +time and this is the end of part two + +0:37:46.160,0:37:52.240 +part three of this presentation is uh + +0:37:49.359,0:37:54.800 +about the killer features of ev or why + +0:37:52.240,0:37:57.920 +everybody should use av or at least have + +0:37:54.800,0:37:59.280 +eev installed even if they think the tv + +0:37:57.920,0:38:01.440 +is too weird + +0:37:59.280,0:38:03.440 +so this is a very quick listing eevee + +0:38:01.440,0:38:04.240 +has lease hyperlinks which are super + +0:38:03.440,0:38:06.560 +nice + +0:38:04.240,0:38:07.599 +it comes with lots of tutorials the main + +0:38:06.560,0:38:10.800 +one here + +0:38:07.599,0:38:14.079 +explains all the main features + +0:38:10.800,0:38:15.040 +uh there's also a tutorial with that's + +0:38:14.079,0:38:18.079 +an index of + +0:38:15.040,0:38:21.680 +all the other tutorials here + +0:38:18.079,0:38:24.079 +many many many tutorials uh if we forget + +0:38:21.680,0:38:27.280 +everything we can just type meta j + +0:38:24.079,0:38:28.880 +and remember that this this part here is + +0:38:27.280,0:38:30.839 +beginner friendly and the rest is + +0:38:28.880,0:38:32.960 +beginner + +0:38:30.839,0:38:38.079 +unfriendly + +0:38:32.960,0:38:38.079 +there's a tutorial on max list here + +0:38:38.320,0:38:44.640 +it mainly explains how to understand + +0:38:41.920,0:38:46.320 +a lisp code which is much easier than + +0:38:44.640,0:38:47.040 +it's much easier to understand the lisp + +0:38:46.320,0:38:48.800 +code and + +0:38:47.040,0:38:50.160 +then to understand how to program in a + +0:38:48.800,0:38:53.440 +lisp and + +0:38:50.160,0:38:55.920 +most people are only going to need this + +0:38:53.440,0:38:58.240 +uh ev is very easy to install it's in + +0:38:55.920,0:39:00.560 +helper so we just need to do + +0:38:58.240,0:39:03.440 +this thing here and it's very + +0:39:00.560,0:39:03.440 +non-invasive + +0:39:03.520,0:39:08.000 +uh years ago several years ago it was a + +0:39:06.079,0:39:08.960 +very invasive package but then i changed + +0:39:08.000,0:39:13.520 +everything + +0:39:08.960,0:39:16.640 +now uh if we toggle ev mode on and off + +0:39:13.520,0:39:20.000 +what's going to happen is just that the + +0:39:16.640,0:39:21.599 +evk map key map becomes activated or + +0:39:20.000,0:39:24.720 +deactivated + +0:39:21.599,0:39:28.320 +and when we install the evita + +0:39:24.720,0:39:28.640 +i mean when we require the only things + +0:39:28.320,0:39:32.640 +that + +0:39:28.640,0:39:34.480 +happens globally distance here + +0:39:32.640,0:39:36.240 +several functions and variables become + +0:39:34.480,0:39:40.079 +defined all of them have + +0:39:36.240,0:39:43.040 +standard prefixes except for one + +0:39:40.079,0:39:44.480 +three characters are changed in the + +0:39:43.040,0:39:48.640 +standard display table + +0:39:44.480,0:39:52.079 +to make them appear as colored glyphs + +0:39:48.640,0:39:54.160 +the red star and two and the open + +0:39:52.079,0:39:57.839 +double angle brackets and the closed + +0:39:54.160,0:39:57.839 +double angle brackets + +0:39:58.160,0:40:04.560 +and two environment variables are set + +0:40:01.359,0:40:07.599 +and this is a trivial technicality + +0:40:04.560,0:40:10.160 +we just run a def advice + +0:40:07.599,0:40:10.800 +around one function that that is used by + +0:40:10.160,0:40:14.240 +man + +0:40:10.800,0:40:16.720 +justice also + +0:40:14.240,0:40:18.400 +eevee has a very high discoverability + +0:40:16.720,0:40:21.839 +factor + +0:40:18.400,0:40:25.200 +and there's a way to create a very easy + +0:40:21.839,0:40:27.760 +way to create a hyperlink to here + +0:40:25.200,0:40:29.760 +uh i do not have time to show this now + +0:40:27.760,0:40:32.960 +but for example if i'm + +0:40:29.760,0:40:34.480 +here in a tutorial and i think that that + +0:40:32.960,0:40:36.240 +this + +0:40:34.480,0:40:39.520 +section is something interesting and i + +0:40:36.240,0:40:41.200 +want to create a hyperlink to it + +0:40:39.520,0:40:43.040 +i just have to type a certain key + +0:40:41.200,0:40:46.800 +sequence here + +0:40:43.040,0:40:50.400 +and here i got a hyperlink that i can + +0:40:46.800,0:40:52.260 +copy to my notes and this hyperlink goes + +0:40:50.400,0:40:58.240 +to that section + +0:40:52.260,0:41:00.720 +[Music] + +0:40:58.240,0:41:02.319 +we have hyperlinks that point to + +0:41:00.720,0:41:05.839 +specific positions in + +0:41:02.319,0:41:09.119 +pdf documents and nvidia files here + +0:41:05.839,0:41:09.680 +this one opens a pdf and displays it + +0:41:09.119,0:41:13.920 +this one + +0:41:09.680,0:41:16.720 +opens a pdf and converts it to text + +0:41:13.920,0:41:18.400 +and this one opens the video in a + +0:41:16.720,0:41:20.480 +certain position + +0:41:18.400,0:41:22.079 +and we also have a way to control + +0:41:20.480,0:41:25.280 +shell-like programs + +0:41:22.079,0:41:27.440 +uh in my presentation of the last year i + +0:41:25.280,0:41:29.520 +spent one third of the presentation + +0:41:27.440,0:41:31.839 +explaining this and i think that i gave + +0:41:29.520,0:41:35.680 +a very good demonstration there + +0:41:31.839,0:41:38.800 +the demonstration is here + +0:41:35.680,0:41:41.839 +we can go to the web page and go to + +0:41:38.800,0:41:45.440 +this section of the web page + +0:41:41.839,0:41:45.440 +and start by this point + +0:41:47.680,0:41:54.079 +and here we have an explanation and so + +0:41:51.440,0:41:54.079 +on whatever + +0:41:55.920,0:41:59.200 +and i've already mentioned this before + +0:41:58.720,0:42:01.119 +uh + +0:41:59.200,0:42:02.240 +eevee comes with a very nice elise + +0:42:01.119,0:42:04.240 +tutorial + +0:42:02.240,0:42:05.599 +so that's it this is the end of part + +0:42:04.240,0:42:07.359 +three + +0:42:05.599,0:42:09.839 +so this is the last part of my + +0:42:07.359,0:42:10.160 +presentation and it's about the title of + +0:42:09.839,0:42:11.839 +the + +0:42:10.160,0:42:13.599 +the presentation i called the + +0:42:11.839,0:42:16.560 +presentation why + +0:42:13.599,0:42:16.960 +most of the best features in eevee look + +0:42:16.560,0:42:20.480 +like + +0:42:16.960,0:42:20.960 +like five minute hacks uh i've already + +0:42:20.480,0:42:23.920 +run off + +0:42:20.960,0:42:24.800 +out of time so i have to to skip this + +0:42:23.920,0:42:28.720 +first + +0:42:24.800,0:42:31.280 +part here in which i describe how i + +0:42:28.720,0:42:33.440 +was exposed to several different notions + +0:42:31.280,0:42:35.920 +of user friendliness + +0:42:33.440,0:42:37.119 +and how the one that really blew my mind + +0:42:35.920,0:42:41.680 +was the one in + +0:42:37.119,0:42:44.160 +in a certain uh fought environment + +0:42:41.680,0:42:46.560 +uh and let me make the long long story + +0:42:44.160,0:42:49.280 +very very short + +0:42:46.560,0:42:49.680 +uh in all this process i switched from + +0:42:49.280,0:42:52.079 +from + +0:42:49.680,0:42:52.960 +the belief that the user was always + +0:42:52.079,0:42:55.359 +someone else + +0:42:52.960,0:42:57.040 +someone external and that that i always + +0:42:55.359,0:43:00.079 +had to write my programs for + +0:42:57.040,0:43:02.240 +this external user i switched + +0:43:00.079,0:43:03.200 +from from that to the belief that i am + +0:43:02.240,0:43:05.839 +the user + +0:43:03.200,0:43:07.040 +and i can play with the interface that i + +0:43:05.839,0:43:10.079 +want i can + +0:43:07.040,0:43:12.079 +write programs which that + +0:43:10.079,0:43:14.240 +that only i am going to understand i can + +0:43:12.079,0:43:16.079 +experiment with hundreds of interfaces + +0:43:14.240,0:43:18.720 +and then select the best ones + +0:43:16.079,0:43:20.960 +and document them and then share them + +0:43:18.720,0:43:23.520 +with other people + +0:43:20.960,0:43:24.720 +who are also experimenting with + +0:43:23.520,0:43:28.880 +interfaces in their + +0:43:24.720,0:43:31.119 +own ways and so eevee has + +0:43:28.880,0:43:33.440 +lots of things that are user-friendly in + +0:43:31.119,0:43:34.880 +these unusual ways that i've explained + +0:43:33.440,0:43:37.760 +before + +0:43:34.880,0:43:40.319 +and uh and if we disconsider that this + +0:43:37.760,0:43:44.079 +notion of user friendliness is valid + +0:43:40.319,0:43:45.119 +then this implement these things that av + +0:43:44.079,0:43:47.280 +implement they are + +0:43:45.119,0:43:48.800 +user friendly and hacker friendly at the + +0:43:47.280,0:43:51.119 +same time + +0:43:48.800,0:43:51.920 +and let me show one example this is one + +0:43:51.119,0:43:54.640 +this is + +0:43:51.920,0:43:56.640 +one that really took me one only five + +0:43:54.640,0:43:59.599 +minutes to implement + +0:43:56.640,0:44:00.640 +uh at one point a few months ago i + +0:43:59.599,0:44:04.240 +discovered + +0:44:00.640,0:44:05.599 +that sasha chewer's weekly posts about + +0:44:04.240,0:44:08.800 +the max news + +0:44:05.599,0:44:11.440 +had uh were also being posted to a + +0:44:08.800,0:44:14.800 +mailing list that is stored at + +0:44:11.440,0:44:16.319 +lists.we know.org and it's called max + +0:44:14.800,0:44:19.280 +dungeons + +0:44:16.319,0:44:19.760 +uh and i just and i found a way to + +0:44:19.280,0:44:25.440 +create + +0:44:19.760,0:44:28.400 +the links to to the posts in both places + +0:44:25.440,0:44:30.640 +but i had to use a template for that so + +0:44:28.400,0:44:32.560 +what we are seeing here now + +0:44:30.640,0:44:36.640 +is a template with the the default + +0:44:32.560,0:44:39.359 +values so this means that we have not uh + +0:44:36.640,0:44:40.720 +set the year correctly we have not set + +0:44:39.359,0:44:44.240 +the month correctly + +0:44:40.720,0:44:44.720 +or the day correctly but if we run this + +0:44:44.240,0:44:48.960 +text + +0:44:44.720,0:44:53.359 +here uh let me do something else before + +0:44:48.960,0:44:57.280 +if we run this text here + +0:44:53.359,0:45:00.240 +which we change some of these + +0:44:57.280,0:45:00.240 +entries in the + +0:45:00.880,0:45:05.200 +in the template and we get these links + +0:45:04.400,0:45:09.119 +here + +0:45:05.200,0:45:12.160 +they all work for example this one opens + +0:45:09.119,0:45:12.800 +uh the blog post in in session sasha + +0:45:12.160,0:45:16.000 +chewers + +0:45:12.800,0:45:21.280 +site and this one + +0:45:16.000,0:45:23.440 +opens it in the mailing list + +0:45:21.280,0:45:25.760 +and sometimes i want the org source of + +0:45:23.440,0:45:27.280 +that and the easiest way to get the word + +0:45:25.760,0:45:30.480 +source is to + +0:45:27.280,0:45:31.680 +look at this link here that has an + +0:45:30.480,0:45:35.040 +attachment + +0:45:31.680,0:45:38.560 +and if i take this + +0:45:35.040,0:45:42.319 +link here and i take this + +0:45:38.560,0:45:44.480 +stem that points to

well uh hello everyone + +0:00:07.359,0:00:11.519 +i hope uh you're all enjoying the emacs + +0:00:09.840,0:00:14.480 +conf + +0:00:11.519,0:00:15.040 +my name is musa alhassi and i hope + +0:00:14.480,0:00:17.920 +you're + +0:00:15.040,0:00:19.840 +excited to learn about uh powering up + +0:00:17.920,0:00:22.880 +special blocks + +0:00:19.840,0:00:24.800 +um so let's let's first off uh find out + +0:00:22.880,0:00:27.920 +what these special blocks are and + +0:00:24.800,0:00:30.240 +and see what we can uh go from so + +0:00:27.920,0:00:32.719 +uh yesterday i saw a lot of cool talks + +0:00:30.240,0:00:33.200 +and uh people were chatting about how do + +0:00:32.719,0:00:35.520 +you + +0:00:33.200,0:00:37.200 +i know how should you present should you + +0:00:35.520,0:00:38.640 +do it this way or that way and + +0:00:37.200,0:00:41.120 +i thought maybe i should try a different + +0:00:38.640,0:00:42.239 +way uh but but i'm talking about special + +0:00:41.120,0:00:45.039 +blocks and if i + +0:00:42.239,0:00:47.039 +show you an emax then i have to export + +0:00:45.039,0:00:47.840 +the html so you can see what it looks + +0:00:47.039,0:00:50.800 +like + +0:00:47.840,0:00:51.920 +or export to a pdf so you can see what + +0:00:50.800,0:00:54.239 +it looks like + +0:00:51.920,0:00:56.399 +uh so i ended up writing an org reveal + +0:00:54.239,0:00:58.960 +and + +0:00:56.399,0:01:00.879 +joyously this this just works you can + +0:00:58.960,0:01:02.960 +you can just see things here + +0:01:00.879,0:01:04.559 +uh i was worried that i'd have to take + +0:01:02.960,0:01:07.600 +pictures and then you know + +0:01:04.559,0:01:09.760 +uh uh you know insert pings so that that + +0:01:07.600,0:01:12.159 +was a delight + +0:01:09.760,0:01:12.960 +okay uh so special blocks are these + +0:01:12.159,0:01:16.000 +things like + +0:01:12.960,0:01:17.280 +a center small quote uh that's what a + +0:01:16.000,0:01:19.360 +special block is + +0:01:17.280,0:01:20.720 +and with a bit of lisp we can we can + +0:01:19.360,0:01:23.200 +make special blocks + +0:01:20.720,0:01:24.799 +and link types right so uh using a + +0:01:23.200,0:01:26.720 +single interface + +0:01:24.799,0:01:27.840 +um and the interface is going to be + +0:01:26.720,0:01:29.439 +similar to one + +0:01:27.840,0:01:32.560 +many people are familiar with in + +0:01:29.439,0:01:35.840 +particular org babel's + +0:01:32.560,0:01:37.840 +source interface as well as using global + +0:01:35.840,0:01:39.680 +header arguments for link types + +0:01:37.840,0:01:41.200 +and the idea is to write it once and + +0:01:39.680,0:01:44.159 +generate many different kinds + +0:01:41.200,0:01:44.720 +right you write uh an org markup and you + +0:01:44.159,0:01:47.680 +can have + +0:01:44.720,0:01:48.560 +uh html you can have pdf and and + +0:01:47.680,0:01:51.840 +joyously + +0:01:48.560,0:01:53.600 +uh org reveal so that was uh that was an + +0:01:51.840,0:01:56.640 +unexpected delight + +0:01:53.600,0:01:57.840 +um so here is a few that you'll you'll + +0:01:56.640,0:02:01.759 +just see as we + +0:01:57.840,0:02:04.000 +uh in this presentation you know some uh + +0:02:01.759,0:02:05.040 +uh i won't show some of these uh link + +0:02:04.000,0:02:06.799 +only ones + +0:02:05.040,0:02:08.080 +but we'll see a few of these other ones + +0:02:06.799,0:02:09.920 +just to make the uh + +0:02:08.080,0:02:11.520 +presentation look nice so the + +0:02:09.920,0:02:14.000 +presentation is really going to + +0:02:11.520,0:02:15.120 +present these blocks and the mechanism + +0:02:14.000,0:02:18.400 +at the same time + +0:02:15.120,0:02:21.280 +so uh so this no no html was written + +0:02:18.400,0:02:22.000 +look ma no html just pure org mode and + +0:02:21.280,0:02:23.520 +and + +0:02:22.000,0:02:25.840 +you get all these beautiful boxes and + +0:02:23.520,0:02:27.680 +things okay + +0:02:25.840,0:02:29.120 +so the motivation for this is you know + +0:02:27.680,0:02:31.200 +what uh + +0:02:29.120,0:02:32.239 +you're you're online you run into a blog + +0:02:31.200,0:02:33.120 +and you see something you like and + +0:02:32.239,0:02:35.280 +you're like man + +0:02:33.120,0:02:36.640 +you know i wish i could uh you know + +0:02:35.280,0:02:39.519 +produce that + +0:02:36.640,0:02:40.160 +um uh but you you check in the author + +0:02:39.519,0:02:44.239 +wrote raw + +0:02:40.160,0:02:46.800 +html you know plus html everywhere + +0:02:44.239,0:02:47.840 +and uh that's that's you know gonna + +0:02:46.800,0:02:49.680 +obscure + +0:02:47.840,0:02:51.200 +your your real content it's going to be + +0:02:49.680,0:02:54.239 +surrounded by all this uh + +0:02:51.200,0:02:56.400 +styling information that's unfortunate + +0:02:54.239,0:02:58.959 +uh the author decides to use an org + +0:02:56.400,0:03:01.120 +macro all right a bit better + +0:02:58.959,0:03:03.360 +but then what if you decide hey i want + +0:03:01.120,0:03:06.000 +to make a + +0:03:03.360,0:03:07.840 +not pdf great and then the worst of all + +0:03:06.000,0:03:10.159 +the author doesn't give you the source + +0:03:07.840,0:03:10.879 +and then you have to view page source + +0:03:10.159,0:03:13.760 +and + +0:03:10.879,0:03:14.239 +learn cascading style sheets and and you + +0:03:13.760,0:03:16.159 +know + +0:03:14.239,0:03:18.080 +sit in a corner and cry decide to do + +0:03:16.159,0:03:20.959 +other things with your life + +0:03:18.080,0:03:22.640 +so uh we want to give you org users + +0:03:20.959,0:03:26.000 +numerous styles + +0:03:22.640,0:03:27.200 +and uh and an extensible mechanism to + +0:03:26.000,0:03:28.799 +add more of these + +0:03:27.200,0:03:31.200 +aesthetically pleasing styles you know + +0:03:28.799,0:03:34.720 +to have really nice things + +0:03:31.200,0:03:35.599 +look one way in the html and look almost + +0:03:34.720,0:03:39.120 +the same way + +0:03:35.599,0:03:41.680 +in the pdf and other uh back ends and + +0:03:39.120,0:03:42.159 +if by having these newer ones you know + +0:03:41.680,0:03:44.879 +people + +0:03:42.159,0:03:45.519 +might be encouraged to try making new + +0:03:44.879,0:03:47.920 +ones + +0:03:45.519,0:03:49.040 +especially when the interface is uh not + +0:03:47.920,0:03:54.080 +so difficult + +0:03:49.040,0:03:54.080 +uh that's the that's the aim okay + +0:03:54.159,0:03:59.120 +uh so let's let's have a a real story to + +0:03:57.360,0:04:02.319 +motivate this even more + +0:03:59.120,0:04:03.599 +um so here's three friends uh i hope i + +0:04:02.319,0:04:04.640 +don't butcher their names but these + +0:04:03.599,0:04:07.040 +friends are called + +0:04:04.640,0:04:08.720 +amin sasha and corwin and then they're + +0:04:07.040,0:04:12.080 +organizing a conference + +0:04:08.720,0:04:14.239 +uh emacs conf 2020. + +0:04:12.080,0:04:16.479 +so sasha decides to write an org file + +0:04:14.239,0:04:19.199 +and and she would like some feedback + +0:04:16.479,0:04:19.840 +okay and and just uh make it clear + +0:04:19.199,0:04:22.960 +there's no + +0:04:19.840,0:04:27.199 +uh just how easy this looks + +0:04:22.960,0:04:27.199 +let's look at the source for this block + +0:04:27.280,0:04:30.720 +notice it's just the word green then a + +0:04:30.000,0:04:34.560 +colon + +0:04:30.720,0:04:37.759 +than amine uh so no + +0:04:34.560,0:04:38.479 +no div style coloring just just you know + +0:04:37.759,0:04:41.520 +green color + +0:04:38.479,0:04:43.600 +immune a very pleasant uh or markup + +0:04:41.520,0:04:44.960 +so that's that's quite nice put some + +0:04:43.600,0:04:47.840 +bold around it + +0:04:44.960,0:04:49.040 +not not too difficult so hopefully uh + +0:04:47.840,0:04:51.680 +this will be useful to + +0:04:49.040,0:04:52.240 +other people as well so what kind of + +0:04:51.680,0:04:56.639 +feedback + +0:04:52.240,0:04:59.120 +uh would sasha expect to get um so maybe + +0:04:56.639,0:04:59.680 +she would expect top level remarks + +0:04:59.120,0:05:01.759 +visible + +0:04:59.680,0:05:04.400 +in the export you know when she makes an + +0:05:01.759,0:05:07.840 +html she can see right there a big block + +0:05:04.400,0:05:09.840 +right maybe + +0:05:07.840,0:05:11.120 +amin will suggest to sasha please + +0:05:09.840,0:05:12.960 +replace this part + +0:05:11.120,0:05:14.639 +with this other part or replace this + +0:05:12.960,0:05:16.960 +word with this other word + +0:05:14.639,0:05:17.680 +right um this is not really possible + +0:05:16.960,0:05:21.919 +with raw + +0:05:17.680,0:05:24.000 +html or uh yeah or with even latex + +0:05:21.919,0:05:25.360 +you'd have to have multiple arguments + +0:05:24.000,0:05:27.840 +the first argument and then + +0:05:25.360,0:05:28.800 +the replacement argument and it's a bit + +0:05:27.840,0:05:30.960 +clunky + +0:05:28.800,0:05:32.080 +um but with our setup you just write + +0:05:30.960,0:05:34.479 +some text + +0:05:32.080,0:05:36.240 +write hashtag plus replace with and then + +0:05:34.479,0:05:39.440 +write more text and you're good to go + +0:05:36.240,0:05:40.720 +normal uh org markup um + +0:05:39.440,0:05:42.479 +everyone speaks different languages + +0:05:40.720,0:05:45.919 +maybe they want to use a + +0:05:42.479,0:05:48.000 +uh one word or they're arguing about + +0:05:45.919,0:05:49.759 +whether we talk about frames or windows + +0:05:48.000,0:05:50.560 +um so maybe they want to have some + +0:05:49.759,0:05:52.479 +translations + +0:05:50.560,0:05:55.360 +right so there's different kinds of + +0:05:52.479,0:05:59.360 +feedbacks uh let's let's take an example + +0:05:55.360,0:06:02.560 +uh look at what they are okay + +0:05:59.360,0:06:06.160 +uh so for example sasha might write + +0:06:02.560,0:06:08.319 +uh this org mode right here and uh + +0:06:06.160,0:06:09.759 +and then in her html exports you might + +0:06:08.319,0:06:12.080 +see this + +0:06:09.759,0:06:13.840 +and uh her feedback might look really + +0:06:12.080,0:06:14.560 +nicely from anyone who says you know + +0:06:13.840,0:06:16.639 +let's uh + +0:06:14.560,0:06:18.560 +let's do some lisp instead of uh + +0:06:16.639,0:06:20.960 +mathematics let's just do some list + +0:06:18.560,0:06:22.479 +and and corwin says you know let's let's + +0:06:20.960,0:06:25.120 +not be so silly + +0:06:22.479,0:06:27.360 +maybe let's just say 9 a.m and move on + +0:06:25.120,0:06:27.360 +okay + +0:06:28.080,0:06:33.039 +um so amin likes to export to pdf + +0:06:31.360,0:06:34.720 +and so he writes his top-level remarks + +0:06:33.039,0:06:37.600 +using latex that's how + +0:06:34.720,0:06:38.960 +so to get this uh square i mean please + +0:06:37.600,0:06:41.440 +change whatever + +0:06:38.960,0:06:43.120 +he might write like this hashtag you + +0:06:41.440,0:06:46.960 +know plus latex + +0:06:43.120,0:06:50.000 +hashtag plus latex right but then + +0:06:46.960,0:06:50.880 +sasha only exports to p to html uh for + +0:06:50.000,0:06:54.880 +example + +0:06:50.880,0:06:57.199 +um and uh so she doesn't look at the pdf + +0:06:54.880,0:06:58.560 +and she may not see his top-level + +0:06:57.199,0:06:59.440 +feedback you know with those nice + +0:06:58.560,0:07:02.160 +brackets and + +0:06:59.440,0:07:03.120 +and bold right and so she might think + +0:07:02.160,0:07:06.160 +everything's good + +0:07:03.120,0:07:09.039 +right and that can be a bit disastrous + +0:07:06.160,0:07:09.440 +um so maybe sasha will will then uh make + +0:07:09.039,0:07:13.199 +some + +0:07:09.440,0:07:16.160 +of her own feedback all right uh but + +0:07:13.199,0:07:16.560 +and to produce it she might write html + +0:07:16.160,0:07:20.639 +uh + +0:07:16.560,0:07:21.680 +um html commands hashtag plus html to + +0:07:20.639,0:07:24.240 +get that + +0:07:21.680,0:07:25.680 +uh but then amin will make a pdf and + +0:07:24.240,0:07:27.759 +this won't stick out + +0:07:25.680,0:07:30.160 +and then so he might think everything's + +0:07:27.759,0:07:33.520 +okay even even though it's not + +0:07:30.160,0:07:36.240 +um then corwin actually decides hey + +0:07:33.520,0:07:36.800 +uh let me read the exported result and + +0:07:36.240,0:07:38.319 +these + +0:07:36.800,0:07:39.919 +there's all those feedback from two + +0:07:38.319,0:07:42.080 +people who haven't uh + +0:07:39.919,0:07:43.840 +read anything because maybe they were in + +0:07:42.080,0:07:46.400 +a russian and didn't + +0:07:43.840,0:07:48.160 +see the top level feedback and so they + +0:07:46.400,0:07:50.000 +agree hey let's have a uniform org + +0:07:48.160,0:07:53.280 +interface that exports + +0:07:50.000,0:07:54.080 +to both html and pdf make both of us + +0:07:53.280,0:07:57.280 +happy + +0:07:54.080,0:07:58.160 +okay so they decide to use org special + +0:07:57.280,0:08:01.840 +blocks + +0:07:58.160,0:08:04.400 +right um and to set this up they need to + +0:08:01.840,0:08:04.879 +you know maybe read a little bit of lisp + +0:08:04.400,0:08:08.879 +hooks + +0:08:04.879,0:08:10.840 +advice macros to get all of this set up + +0:08:08.879,0:08:12.319 +and then they'll use org as the main + +0:08:10.840,0:08:14.400 +interface okay + +0:08:12.319,0:08:16.479 +it's a lot of work but it's worth it + +0:08:14.400,0:08:19.360 +right maybe + +0:08:16.479,0:08:19.759 +um but then corwin corbin's a bit tears + +0:08:19.360,0:08:22.960 +so + +0:08:19.759,0:08:24.800 +uh corwin maybe doesn't want to write + +0:08:22.960,0:08:26.080 +uh using blocks he thinks they're + +0:08:24.800,0:08:29.360 +overkill and + +0:08:26.080,0:08:31.840 +and sasha wants html and uh and + +0:08:29.360,0:08:32.560 +i mean wants pdf and corwin wants org + +0:08:31.840,0:08:34.240 +reveal + +0:08:32.560,0:08:36.320 +so now they have to reformat all their + +0:08:34.240,0:08:37.120 +code and then they need to use org link + +0:08:36.320,0:08:39.599 +types to + +0:08:37.120,0:08:41.519 +reduce the overkill all right so they + +0:08:39.599,0:08:44.000 +can try to avoid duplication by + +0:08:41.519,0:08:46.800 +factoring things out into self-contained + +0:08:44.000,0:08:50.320 +uh defined functions or defunds + +0:08:46.800,0:08:53.440 +um but now to set up or links + +0:08:50.320,0:08:54.399 +uh we'll have uh to learn a new + +0:08:53.440,0:08:57.040 +interface + +0:08:54.399,0:08:58.000 +org setup link um learn a little bit + +0:08:57.040,0:09:02.160 +about fonts + +0:08:58.000,0:09:05.040 +follow links exports handles + +0:09:02.160,0:09:06.800 +it's so much that's so much but but then + +0:09:05.040,0:09:08.399 +you know the friends they learn a lot + +0:09:06.800,0:09:11.120 +you know they learn about defund all + +0:09:08.399,0:09:12.480 +right so these these words are red + +0:09:11.120,0:09:14.320 +you get a little explanation i think + +0:09:12.480,0:09:16.720 +it's a bit too small for anyone to read + +0:09:14.320,0:09:18.000 +this is lisp documentation right for + +0:09:16.720,0:09:19.680 +defund + +0:09:18.000,0:09:21.600 +advice ad there's some list + +0:09:19.680,0:09:23.600 +documentation right + +0:09:21.600,0:09:25.279 +they learn about destructuring let's so + +0:09:23.600,0:09:26.959 +this is from the dash library + +0:09:25.279,0:09:28.800 +here's all that you know glorious + +0:09:26.959,0:09:29.360 +glorious documentation with examples + +0:09:28.800,0:09:31.680 +sorry + +0:09:29.360,0:09:33.760 +i like that they might make an ad-hoc + +0:09:31.680,0:09:36.000 +mechanism to simulate + +0:09:33.760,0:09:37.040 +arguments for special blocks so + +0:09:36.000,0:09:40.399 +something maybe called + +0:09:37.040,0:09:41.920 +extract arguments and then of course to + +0:09:40.399,0:09:42.480 +make new link types they have to learn + +0:09:41.920,0:09:45.120 +about + +0:09:42.480,0:09:46.480 +org link set parameters and then it's + +0:09:45.120,0:09:49.920 +numerous uh + +0:09:46.480,0:09:50.720 +bits and pieces all right so let's oh + +0:09:49.920,0:09:53.600 +let's uh + +0:09:50.720,0:09:55.040 +close all these ones down and and uh of + +0:09:53.600,0:09:56.080 +course they also need to be uh + +0:09:55.040,0:09:58.720 +comfortable with + +0:09:56.080,0:09:59.920 +uh loops and maps and matching and + +0:09:58.720,0:10:02.560 +string functions + +0:09:59.920,0:10:03.360 +so it's it's a bit of a pain it's a bit + +0:10:02.560,0:10:05.839 +of a pain + +0:10:03.360,0:10:06.560 +um so it's probably not worth it so + +0:10:05.839,0:10:09.360 +maybe i'll just + +0:10:06.560,0:10:10.320 +rush things quickly or do an ad hoc you + +0:10:09.360,0:10:13.680 +know + +0:10:10.320,0:10:15.920 +we have things to do right + +0:10:13.680,0:10:17.839 +so maybe maybe the squad wants to have a + +0:10:15.920,0:10:21.120 +modular + +0:10:17.839,0:10:23.040 +and unified interface so everyone's + +0:10:21.120,0:10:25.279 +comfortable with defunct to define a + +0:10:23.040,0:10:26.480 +function and they say you know what + +0:10:25.279,0:10:29.440 +it would be nice if we could just you + +0:10:26.480,0:10:32.959 +know define simultaneously + +0:10:29.440,0:10:34.880 +both a block and the link type right + +0:10:32.959,0:10:36.000 +and uh that way we have a single + +0:10:34.880,0:10:38.240 +interface + +0:10:36.000,0:10:39.040 +org mode for for these things and it + +0:10:38.240,0:10:42.079 +would be nice was + +0:10:39.040,0:10:43.680 +modular so if i defined a + +0:10:42.079,0:10:45.519 +one kind of block and you defined + +0:10:43.680,0:10:47.600 +another we could compose them + +0:10:45.519,0:10:49.360 +right and then get a you know a nice + +0:10:47.600,0:10:52.320 +bigger block like lego + +0:10:49.360,0:10:54.160 +that would be nice building box okay and + +0:10:52.320,0:10:56.240 +uh this is uh what we + +0:10:54.160,0:10:57.600 +have come up with called death block and + +0:10:56.240,0:11:00.240 +it also has a + +0:10:57.600,0:11:01.760 +long documentation string containing + +0:11:00.240,0:11:04.800 +examples and things + +0:11:01.760,0:11:08.320 +so that way you can try to be useful + +0:11:04.800,0:11:10.880 +okay um so let's let's look at a a + +0:11:08.320,0:11:12.800 +solution to these friends uh trilemma + +0:11:10.880,0:11:14.320 +all right so here's here's a way to + +0:11:12.800,0:11:17.040 +define a block + +0:11:14.320,0:11:19.200 +um it looks it's it doesn't look that + +0:11:17.040,0:11:22.320 +difficult but this is how they can + +0:11:19.200,0:11:25.920 +define a block for um + +0:11:22.320,0:11:27.680 +for uh their top-level feedback right + +0:11:25.920,0:11:28.959 +so let's let's look at the three main + +0:11:27.680,0:11:31.920 +parts together + +0:11:28.959,0:11:33.040 +it's not that uh difficult i hope just + +0:11:31.920,0:11:34.720 +six lines + +0:11:33.040,0:11:36.160 +and that's including a documentation + +0:11:34.720,0:11:39.440 +string and you know + +0:11:36.160,0:11:41.279 +uh new lines and things okay so in line + +0:11:39.440,0:11:42.000 +one we just define the block just like + +0:11:41.279,0:11:44.880 +you define + +0:11:42.000,0:11:46.399 +a function we define a block the flag + +0:11:44.880,0:11:49.680 +the block name is going to be called + +0:11:46.399,0:11:53.360 +feedback it has an author who + +0:11:49.680,0:11:56.160 +right the author has no default + +0:11:53.360,0:11:57.760 +value it has a color and the color has a + +0:11:56.160,0:12:00.560 +default value of red + +0:11:57.760,0:12:01.680 +okay so just just as when you define + +0:12:00.560,0:12:04.880 +functions they + +0:12:01.680,0:12:08.639 +they uh you start by uh define + +0:12:04.880,0:12:10.720 +or def block than the name some + +0:12:08.639,0:12:13.440 +mandatory argument and some optional + +0:12:10.720,0:12:15.760 +arguments okay + +0:12:13.440,0:12:18.480 +then the next stage is well and + +0:12:15.760,0:12:20.880 +definition a documentation you know + +0:12:18.480,0:12:22.880 +uh the people who use this which are + +0:12:20.880,0:12:25.519 +future you or future me you know + +0:12:22.880,0:12:27.839 +uh might want to know what this is all + +0:12:25.519,0:12:30.560 +right so let's get to document this + +0:12:27.839,0:12:32.079 +uh and uh for for corwin who might want + +0:12:30.560,0:12:34.560 +to use uh tooltips + +0:12:32.079,0:12:35.120 +uh when corwin writes feedback whatever + +0:12:34.560,0:12:37.120 +and + +0:12:35.120,0:12:38.639 +emacs they'll see a nice little tooltip + +0:12:37.120,0:12:41.279 +and the tooltip will have + +0:12:38.639,0:12:43.279 +this uh documentation string right so + +0:12:41.279,0:12:45.200 +that'll be nice + +0:12:43.279,0:12:46.480 +okay and then here's the third part the + +0:12:45.200,0:12:49.440 +last three lines are + +0:12:46.480,0:12:49.680 +not not so difficult if the back end is + +0:12:49.440,0:12:52.800 +in + +0:12:49.680,0:12:55.360 +is html the backend is html + +0:12:52.800,0:12:57.440 +please use this template string + +0:12:55.360,0:13:00.639 +otherwise use the other string + +0:12:57.440,0:13:01.279 +okay and for each of these uh string + +0:13:00.639,0:13:03.600 +markers + +0:13:01.279,0:13:04.959 +please put in the color who wrote it and + +0:13:03.600,0:13:07.279 +then the contents + +0:13:04.959,0:13:08.160 +of the special block or the link type + +0:13:07.279,0:13:10.639 +okay + +0:13:08.160,0:13:11.600 +um so that's pretty neat not not so + +0:13:10.639,0:13:14.639 +difficult + +0:13:11.600,0:13:15.519 +so i thought that was kind of cool and + +0:13:14.639,0:13:18.480 +then notice it's + +0:13:15.519,0:13:19.519 +anaphoric it's it's a this this def + +0:13:18.480,0:13:21.760 +block + +0:13:19.519,0:13:22.560 +gives you two new names it gives you a + +0:13:21.760,0:13:25.120 +name called + +0:13:22.560,0:13:26.480 +uh contents and it gives you a name + +0:13:25.120,0:13:29.040 +called back end + +0:13:26.480,0:13:31.040 +right and so even if you're writing a + +0:13:29.040,0:13:32.560 +def block and you intend it to be used + +0:13:31.040,0:13:35.440 +only for links + +0:13:32.560,0:13:37.600 +uh like the uh these colors for example + +0:13:35.440,0:13:38.399 +uh these colors were defined using dev + +0:13:37.600,0:13:41.279 +block + +0:13:38.399,0:13:43.360 +uh and i used them as links right here + +0:13:41.279,0:13:44.880 +and you don't need to worry + +0:13:43.360,0:13:48.160 +where does the text come from in the + +0:13:44.880,0:13:48.959 +link you know if i say red colon bob uh + +0:13:48.160,0:13:50.720 +is it bob + +0:13:48.959,0:13:52.000 +or if i put a description is it the + +0:13:50.720,0:13:54.000 +description so + +0:13:52.000,0:13:56.720 +it's whatever is available will will + +0:13:54.000,0:13:59.199 +become uh the value of contents + +0:13:56.720,0:14:00.320 +and if you're really you know interested + +0:13:59.199,0:14:03.839 +and you want to do some + +0:14:00.320,0:14:04.959 +intricate stuff uh def block also gives + +0:14:03.839,0:14:08.160 +you something called + +0:14:04.959,0:14:09.360 +raw dash contents if you really want to + +0:14:08.160,0:14:11.920 +touch the raw + +0:14:09.360,0:14:12.639 +uh contents with all of the org markups + +0:14:11.920,0:14:16.000 +still there + +0:14:12.639,0:14:18.320 +okay so let's uh let's see + +0:14:16.000,0:14:19.440 +how uh everyone can uh communicate + +0:14:18.320,0:14:22.480 +amongst themselves + +0:14:19.440,0:14:26.000 +using this new interface okay so + +0:14:22.480,0:14:28.399 +uh uh sasha speculates and she how does + +0:14:26.000,0:14:31.440 +she speculate for her organ html + +0:14:28.399,0:14:34.800 +she might just write hey look at that no + +0:14:31.440,0:14:37.519 +no no html nice and and + +0:14:34.800,0:14:39.600 +amin wants to have some green and so he + +0:14:37.519,0:14:42.240 +just says hey here's some color green + +0:14:39.600,0:14:42.959 +and and uh there you go it looks almost + +0:14:42.240,0:14:46.560 +the same + +0:14:42.959,0:14:49.680 +right uh notice that the main argument + +0:14:46.560,0:14:52.480 +is right here def block took an author + +0:14:49.680,0:14:53.920 +and here's the author again and now the + +0:14:52.480,0:14:57.360 +optional argument + +0:14:53.920,0:14:58.000 +uses the org babel source interface you + +0:14:57.360,0:15:00.639 +just say + +0:14:58.000,0:15:01.440 +colon and then a key and then the + +0:15:00.639,0:15:05.040 +argument + +0:15:01.440,0:15:05.519 +quite quite nice and and corwin doesn't + +0:15:05.040,0:15:07.920 +want to + +0:15:05.519,0:15:09.760 +use blocks it's a bit of an overkill and + +0:15:07.920,0:15:12.959 +can just write a + +0:15:09.760,0:15:16.000 +a little um right + +0:15:12.959,0:15:17.440 +so the main argument is now the uh uh + +0:15:16.000,0:15:19.360 +the label of the link + +0:15:17.440,0:15:21.600 +all right and then the description of + +0:15:19.360,0:15:24.959 +the link is the contents + +0:15:21.600,0:15:25.680 +of uh of the feedback so that was quite + +0:15:24.959,0:15:28.079 +nice + +0:15:25.680,0:15:29.360 +so it looks like uh everyone uses the + +0:15:28.079,0:15:32.800 +same interface on the left + +0:15:29.360,0:15:34.480 +and can have varying uh outputs + +0:15:32.800,0:15:36.639 +and it looks i think it looks quite nice + +0:15:34.480,0:15:40.000 +and i hope you do too + +0:15:36.639,0:15:42.160 +um and there's a few more maybe + +0:15:40.000,0:15:43.920 +as you saw in some previous ones we had + +0:15:42.160,0:15:46.800 +text side beside side + +0:15:43.920,0:15:47.440 +right now um or we folded some regions + +0:15:46.800,0:15:49.360 +away + +0:15:47.440,0:15:50.959 +that was quite nice we put some things + +0:15:49.360,0:15:54.000 +in pretty boxes + +0:15:50.959,0:15:57.120 +um uh we had some spoilers at the very + +0:15:54.000,0:15:58.160 +beginning that we we uh hit some text uh + +0:15:57.120,0:15:59.600 +we demoed uh + +0:15:58.160,0:16:01.680 +some texts right you know here's some + +0:15:59.600,0:16:04.480 +org and here's what it looks like + +0:16:01.680,0:16:05.199 +um and and most importantly uh they they + +0:16:04.480,0:16:08.320 +compose + +0:16:05.199,0:16:12.639 +right there's uh uh there's a + +0:16:08.320,0:16:14.720 +a macro called uh uh thread block + +0:16:12.639,0:16:16.160 +uh thread block a thread block call and + +0:16:14.720,0:16:18.000 +it lets you thread the + +0:16:16.160,0:16:20.639 +the contents through a number of blocks + +0:16:18.000,0:16:22.480 +treating them as if they were functions + +0:16:20.639,0:16:23.680 +and so really you can think of a block + +0:16:22.480,0:16:26.560 +as a as a + +0:16:23.680,0:16:27.360 +as a string valued function so that's + +0:16:26.560,0:16:30.959 +pretty neat + +0:16:27.360,0:16:31.759 +i i think and uh thank you for listening + +0:16:30.959,0:16:34.320 +and uh + +0:16:31.759,0:16:34.880 +i i hope you've uh enjoyed this little + +0:16:34.320,0:16:37.600 +uh + +0:16:34.880,0:16:38.160 +happy fun time with uh with the emacs + +0:16:37.600,0:16:40.720 +and friends + +0:16:38.160,0:16:41.759 +and uh i'll i'm i'll happy happily + +0:16:40.720,0:16:43.730 +answer questions + +0:16:41.759,0:16:45.360 +uh right now um + +0:16:43.730,0:16:48.160 +[Music] + +0:16:45.360,0:16:50.480 +so uh someone says why did you put + +0:16:48.160,0:16:53.600 +optional arguments in a separate list + +0:16:50.480,0:16:54.560 +rather than using cl style argument + +0:16:53.600,0:16:58.399 +lists + +0:16:54.560,0:17:01.680 +um so that's a very good question + +0:16:58.399,0:17:04.400 +and i will answer that by + +0:17:01.680,0:17:04.880 +showing you a more involved definition + +0:17:04.400,0:17:08.959 +of + +0:17:04.880,0:17:12.079 +feedback so let's look at a + +0:17:08.959,0:17:12.079 +a more involved one + +0:17:13.039,0:17:19.280 +right right here so for example + +0:17:16.079,0:17:21.760 +this one is called rural mark all right + +0:17:19.280,0:17:23.439 +and uh please let me know if my text is + +0:17:21.760,0:17:26.799 +not sufficiently big + +0:17:23.439,0:17:29.520 +so here is here is why uh we have + +0:17:26.799,0:17:30.720 +two arguments that takes two arguments + +0:17:29.520,0:17:33.360 +uh instead of one + +0:17:30.720,0:17:34.799 +for for its argument list right so you + +0:17:33.360,0:17:37.679 +you have def block + +0:17:34.799,0:17:38.400 +then you have the name right then you + +0:17:37.679,0:17:40.960 +have + +0:17:38.400,0:17:42.880 +the first uh argument list and the + +0:17:40.960,0:17:46.080 +second argument list + +0:17:42.880,0:17:49.280 +the first argument list uh takes the + +0:17:46.080,0:17:51.760 +takes the text right after the begin + +0:17:49.280,0:17:52.320 +right the text right after the begin is + +0:17:51.760,0:17:55.760 +the main + +0:17:52.320,0:17:57.039 +argument okay and then the remaining key + +0:17:55.760,0:18:00.320 +value pairs + +0:17:57.039,0:18:03.280 +are in the second argument list okay + +0:18:00.320,0:18:04.640 +now the reason we have two is because uh + +0:18:03.280,0:18:06.799 +in order to + +0:18:04.640,0:18:08.880 +streamline the interface to account for + +0:18:06.799,0:18:12.320 +both uh special blocks + +0:18:08.880,0:18:13.360 +and or link types uh what we do is we + +0:18:12.320,0:18:16.160 +say hey + +0:18:13.360,0:18:18.000 +uh in the first argument list uh you can + +0:18:16.160,0:18:21.039 +give a name to the first argument + +0:18:18.000,0:18:24.240 +give it a default value and anything + +0:18:21.039,0:18:27.760 +else you provide will become uh + +0:18:24.240,0:18:30.000 +uh part of the i'll co link + +0:18:27.760,0:18:32.000 +information so for example this link we + +0:18:30.000,0:18:34.799 +decided to make its face + +0:18:32.000,0:18:35.840 +angry red um you might want to give + +0:18:34.799,0:18:37.919 +other features to + +0:18:35.840,0:18:39.679 +links so we're trying to streamline the + +0:18:37.919,0:18:42.320 +interface for both + +0:18:39.679,0:18:42.880 +special blocks and org link types and we + +0:18:42.320,0:18:46.240 +thought + +0:18:42.880,0:18:49.840 +this way was quite nice um so + +0:18:46.240,0:18:52.480 +that was the main reason uh someone asks + +0:18:49.840,0:18:55.039 +uh so if if you uh if that's uh if you + +0:18:52.480,0:18:57.600 +need if you have follow-up please ask + +0:18:55.039,0:19:00.559 +someone asks do you intend to try to + +0:18:57.600,0:19:03.600 +upstream this amazing work into org + +0:19:00.559,0:19:04.559 +well i'm glad you like it i i don't know + +0:19:03.600,0:19:06.880 +how to upstream + +0:19:04.559,0:19:08.799 +but but i i will look into it and any + +0:19:06.880,0:19:11.840 +advice or guidance would be + +0:19:08.799,0:19:14.640 +much appreciated um you know + +0:19:11.840,0:19:17.120 +lisp is awesome and just as defunded as + +0:19:14.640,0:19:20.240 +a macro deathblock is a macro and then + +0:19:17.120,0:19:21.919 +source blocks are awesome and then now + +0:19:20.240,0:19:24.080 +maybe we can have arguments and special + +0:19:21.919,0:19:25.280 +blocks and motivate and encourage more + +0:19:24.080,0:19:28.799 +people to uh + +0:19:25.280,0:19:32.559 +to uh learn lisp right + +0:19:28.799,0:19:35.280 +so another person asks + +0:19:32.559,0:19:38.559 +um what is used to produce colorful + +0:19:35.280,0:19:40.400 +boxes around the cursor + +0:19:38.559,0:19:41.840 +i i'm not quite sure if you're asking + +0:19:40.400,0:19:42.559 +are you talking about my cursor right + +0:19:41.840,0:19:47.840 +here + +0:19:42.559,0:19:47.840 +or are you talking about in the slide um + +0:19:48.400,0:19:52.400 +so this this this cursor is some + +0:19:50.559,0:19:55.440 +application called + +0:19:52.400,0:19:57.679 +a stream brush that i had to purchase uh + +0:19:55.440,0:19:59.039 +unfortunately i could not find a a + +0:19:57.679,0:20:02.159 +suitable free one + +0:19:59.039,0:20:03.840 +um and the blocks i can demonstrate some + +0:20:02.159,0:20:05.679 +emacs list but i can open up my emacs if + +0:20:03.840,0:20:06.320 +people like and we can try some things + +0:20:05.679,0:20:09.440 +out + +0:20:06.320,0:20:12.480 +happy to do that uh + +0:20:09.440,0:20:14.880 +you're welcome uh someone asks + +0:20:12.480,0:20:15.520 +a side question about org reveal how do + +0:20:14.880,0:20:17.440 +you get + +0:20:15.520,0:20:19.120 +bespoke or multiple column layouts + +0:20:17.440,0:20:22.559 +without using html + +0:20:19.120,0:20:24.640 +ah excellent question that's what we do + +0:20:22.559,0:20:26.000 +that's that's what this uh project is + +0:20:24.640,0:20:28.960 +about so it's not + +0:20:26.000,0:20:29.440 +org reveal it's it's our fancy parallel + +0:20:28.960,0:20:32.240 +uh + +0:20:29.440,0:20:33.440 +uh block so we have this thing you say + +0:20:32.240,0:20:35.679 +begin parallel + +0:20:33.440,0:20:37.120 +you say how many columns you would like + +0:20:35.679,0:20:39.679 +uh do you want a bar + +0:20:37.120,0:20:40.960 +or not and then you write some text and + +0:20:39.679,0:20:42.480 +then you uh + +0:20:40.960,0:20:44.400 +you get some text and according with the + +0:20:42.480,0:20:47.520 +bar or not right so that's + +0:20:44.400,0:20:50.080 +that's how we achieve that in our slides + +0:20:47.520,0:20:52.559 +so i'm not uh i'm not quite sure where + +0:20:50.080,0:20:52.559 +this was + +0:20:52.880,0:20:55.919 +somewhere here i think + +0:20:59.520,0:21:03.840 +let me try to find this for you + +0:21:06.240,0:21:09.440 +i can't seem to find where the parallel + +0:21:08.320,0:21:12.159 +blocks were + +0:21:09.440,0:21:15.039 +apologies let's move on to the next + +0:21:12.159,0:21:17.760 +question i suppose + +0:21:15.039,0:21:18.400 +uh i'm pretty sure they're here ah there + +0:21:17.760,0:21:21.360 +they are + +0:21:18.400,0:21:22.640 +yes so these these uh were just + +0:21:21.360,0:21:25.440 +instances of using + +0:21:22.640,0:21:26.480 +uh the parallel block and it makes + +0:21:25.440,0:21:29.600 +things parallel + +0:21:26.480,0:21:33.360 +so that's quite nice um another person + +0:21:29.600,0:21:36.720 +asks uh yes + +0:21:33.360,0:21:37.840 +excellent um how does this relate to + +0:21:36.720,0:21:39.360 +banda pandoc + +0:21:37.840,0:21:40.960 +which is used for converting between + +0:21:39.360,0:21:43.919 +markup formats + +0:21:40.960,0:21:44.400 +so all we're doing is we're we're saying + +0:21:43.919,0:21:46.799 +hey + +0:21:44.400,0:21:47.679 +please write org because org is just + +0:21:46.799,0:21:50.400 +fantastic + +0:21:47.679,0:21:51.760 +and we love it and it's the dream and if + +0:21:50.400,0:21:55.039 +you would like to view things + +0:21:51.760,0:21:58.559 +in html or in org reveal or + +0:21:55.039,0:22:02.320 +in pdf that's up to the user so + +0:21:58.559,0:22:05.039 +here is a um oh + +0:22:02.320,0:22:06.080 +made it too small now so here is a an + +0:22:05.039,0:22:08.880 +example + +0:22:06.080,0:22:10.240 +so here's an uh how here's how parallel + +0:22:08.880,0:22:13.120 +is implemented + +0:22:10.240,0:22:14.320 +uh just as a quick example uh not too + +0:22:13.120,0:22:16.880 +long + +0:22:14.320,0:22:18.400 +uh about half of the implementation is + +0:22:16.880,0:22:20.720 +documentation so + +0:22:18.400,0:22:22.720 +uh hopefully that speaks for for how + +0:22:20.720,0:22:25.280 +useful this feature is + +0:22:22.720,0:22:28.080 +uh so we decide if there's a rule or not + +0:22:25.280,0:22:29.760 +um we look for the column break + +0:22:28.080,0:22:31.840 +and really here we're looking at the + +0:22:29.760,0:22:34.960 +back end if the back end is latex + +0:22:31.840,0:22:37.679 +uh please use this uh incantation with + +0:22:34.960,0:22:38.559 +multi columns mini pages what have you + +0:22:37.679,0:22:41.039 +and if the + +0:22:38.559,0:22:41.600 +back end is something else uh please uh + +0:22:41.039,0:22:44.960 +do this + +0:22:41.600,0:22:46.640 +uh div and style and uh other uh + +0:22:44.960,0:22:48.080 +gibberish that we don't really wanna + +0:22:46.640,0:22:51.760 +look at uh so + +0:22:48.080,0:22:55.280 +uh when you pandoc works from org + +0:22:51.760,0:22:58.080 +so it might not work directly since our + +0:22:55.280,0:22:59.679 +interface the way we set it up is when + +0:22:58.080,0:23:01.919 +you try to export + +0:22:59.679,0:23:03.039 +uh we hook in and we do a bunch of + +0:23:01.919,0:23:05.919 +pre-processing + +0:23:03.039,0:23:07.440 +so this this uh def block is a is a + +0:23:05.919,0:23:10.880 +string valued function + +0:23:07.440,0:23:13.919 +and so whenever we see these uh begin + +0:23:10.880,0:23:16.480 +parallel uh when you do an export + +0:23:13.919,0:23:16.960 +i tell emacs hold up look for those + +0:23:16.480,0:23:19.360 +begin + +0:23:16.960,0:23:20.320 +parallels please oh you found them grab + +0:23:19.360,0:23:22.400 +that text + +0:23:20.320,0:23:24.080 +you grabbed it great now please apply + +0:23:22.400,0:23:27.120 +this person's uh function + +0:23:24.080,0:23:29.760 +onto that text and splice in the result + +0:23:27.120,0:23:30.400 +okay so so when you export uh we're + +0:23:29.760,0:23:33.600 +performing + +0:23:30.400,0:23:35.120 +arbitrary computations on your uh uh on + +0:23:33.600,0:23:38.799 +your text + +0:23:35.120,0:23:40.159 +so uh um some people might not find that + +0:23:38.799,0:23:43.039 +comforting to have + +0:23:40.159,0:23:45.039 +arbitrary uh computations happening so + +0:23:43.039,0:23:47.520 +in this article there's a few where + +0:23:45.039,0:23:48.320 +uh we change your text upon export we + +0:23:47.520,0:23:51.760 +translate it + +0:23:48.320,0:23:55.360 +we do other things to it um + +0:23:51.760,0:23:57.360 +so someone says uh if you export to + +0:23:55.360,0:23:58.640 +latex to pdf does that work well with + +0:23:57.360,0:24:00.320 +beamer as well + +0:23:58.640,0:24:02.080 +to create slides with columns for + +0:24:00.320,0:24:05.200 +example for uh + +0:24:02.080,0:24:08.000 +um so uh actually uh + +0:24:05.200,0:24:09.200 +so uh i i made a bunch of these changes + +0:24:08.000,0:24:12.320 +earlier this morning + +0:24:09.200,0:24:14.480 +and it just says latex right here um + +0:24:12.320,0:24:15.360 +so if you want to go to beamer i think + +0:24:14.480,0:24:18.240 +the back end for me + +0:24:15.360,0:24:18.960 +beamer is called well beamer so instead + +0:24:18.240,0:24:21.200 +of a + +0:24:18.960,0:24:22.000 +a p case what we would do is we would + +0:24:21.200,0:24:25.360 +say oh + +0:24:22.000,0:24:29.279 +if it's a latex or it's a beamer + +0:24:25.360,0:24:31.120 +then uh use this uh otherwise + +0:24:29.279,0:24:33.039 +it's not a latex it will simply default + +0:24:31.120,0:24:36.400 +to this one which could be + +0:24:33.039,0:24:39.679 +dangerous for your needs um i think it's + +0:24:36.400,0:24:41.279 +a bad practice to put a underscore but i + +0:24:39.679,0:24:43.679 +did it really quickly because i just + +0:24:41.279,0:24:46.559 +wanted to show you that it works fine in + +0:24:43.679,0:24:47.440 +org reveal contributions are more than + +0:24:46.559,0:24:51.039 +welcome + +0:24:47.440,0:24:52.240 +i i uh happily uh would love any + +0:24:51.039,0:24:56.080 +assistance + +0:24:52.240,0:24:58.640 +um and and i have a uh we have a + +0:24:56.080,0:25:00.159 +list a reference cheat sheet here to to + +0:24:58.640,0:25:02.000 +learn a little bit about lisp if you're + +0:25:00.159,0:25:04.640 +not comfortable or to + +0:25:02.000,0:25:06.400 +ask some questions lots of helpful + +0:25:04.640,0:25:09.440 +people + +0:25:06.400,0:25:11.679 +so there's another question that says uh + +0:25:09.440,0:25:13.120 +does typing in a block mess up with a + +0:25:11.679,0:25:15.679 +syntax highlighting + +0:25:13.120,0:25:17.279 +usually you use a single color inside an + +0:25:15.679,0:25:21.279 +example block for example + +0:25:17.279,0:25:25.279 +ah you found my crutch you found + +0:25:21.279,0:25:27.440 +my crutch um so i so there's + +0:25:25.279,0:25:29.760 +emax's is all encompassing and i'm not + +0:25:27.440,0:25:32.559 +quite sure how fonts work or are + +0:25:29.760,0:25:33.840 +you know i i learned enough to get by i + +0:25:32.559,0:25:37.440 +learned enough to get by + +0:25:33.840,0:25:39.760 +so let me um but here's + +0:25:37.440,0:25:40.799 +here's how links work they're they're a + +0:25:39.760,0:25:42.960 +bit complicated + +0:25:40.799,0:25:43.919 +this this is a bit scary i don't + +0:25:42.960,0:25:47.039 +recommend anyone + +0:25:43.919,0:25:49.840 +uh read it um + +0:25:47.039,0:25:50.559 +but uh actually let me open up an email + +0:25:49.840,0:25:53.600 +and you can + +0:25:50.559,0:25:54.799 +you can see what i see uh so here's an + +0:25:53.600,0:25:56.799 +emacs + +0:25:54.799,0:25:58.400 +all right let's make that a bit bigger + +0:25:56.799,0:26:01.200 +uh let's change this + +0:25:58.400,0:26:01.919 +slightly nope that's worse there you go + +0:26:01.200,0:26:05.760 +so + +0:26:01.919,0:26:09.360 +here's here's some words um so here's + +0:26:05.760,0:26:12.000 +red hello um + +0:26:09.360,0:26:12.400 +but you're worried about uh preserving + +0:26:12.000,0:26:15.679 +uh + +0:26:12.400,0:26:18.480 +uh uh um quantification + +0:26:15.679,0:26:18.880 +so let's make an emax list block all + +0:26:18.480,0:26:22.840 +right + +0:26:18.880,0:26:27.520 +and let's say plus one two ah + +0:26:22.840,0:26:27.520 +where's the fun hello + +0:26:28.000,0:26:34.880 +um bye okay where's the coloring + +0:26:32.080,0:26:36.000 +if we if we zoom in on this on this + +0:26:34.880,0:26:39.200 +begin source block + +0:26:36.000,0:26:42.159 +if we zoom in you can see down here + +0:26:39.200,0:26:43.279 +uh we have our our coloring all right + +0:26:42.159,0:26:46.960 +when we zoom in + +0:26:43.279,0:26:50.080 +if we if we zoom out ah no coloring + +0:26:46.960,0:26:50.880 +zoom in coloring it's about ah no + +0:26:50.080,0:26:53.840 +coloring + +0:26:50.880,0:26:55.679 +let's take off these bad boys and oh + +0:26:53.840,0:26:59.360 +look my coloring's back + +0:26:55.679,0:27:02.320 +so um in a previous + +0:26:59.360,0:27:03.760 +uh iteration of the system i was able to + +0:27:02.320,0:27:06.400 +maintain coloring + +0:27:03.760,0:27:08.559 +uh in this new iteration i am not i + +0:27:06.400,0:27:11.039 +don't know how to do it i haven't uh + +0:27:08.559,0:27:13.279 +had the time to to implement it i spent + +0:27:11.039,0:27:17.279 +a lot of time writing this uh + +0:27:13.279,0:27:19.679 +48 page uh documentation uh with uh + +0:27:17.279,0:27:20.320 +with some fun examples to to to try to + +0:27:19.679,0:27:21.760 +help + +0:27:20.320,0:27:23.760 +people learn so but but i would + +0:27:21.760,0:27:26.240 +appreciate any help or guidance on + +0:27:23.760,0:27:28.000 +how to uh maintain the quantification i + +0:27:26.240,0:27:29.200 +i really would like to keep those colors + +0:27:28.000,0:27:31.840 +in + +0:27:29.200,0:27:32.640 +um musa we have time for maybe one more + +0:27:31.840,0:27:34.960 +question + +0:27:32.640,0:27:37.039 +um one or two more questions and then we + +0:27:34.960,0:27:39.120 +have to move on to the next talk + +0:27:37.039,0:27:40.799 +um but yeah you're more than welcome to + +0:27:39.120,0:27:42.559 +take continue taking the questions via + +0:27:40.799,0:27:45.760 +irc or the pad + +0:27:42.559,0:27:48.480 +okay thank you thank you + +0:27:45.760,0:27:48.880 +let's uh the final question we'll take + +0:27:48.480,0:27:52.320 +is + +0:27:48.880,0:27:54.399 +um should packages implement + +0:27:52.320,0:27:55.840 +interface to one specific format or + +0:27:54.399,0:27:57.279 +attempt to be conclusive to all the + +0:27:55.840,0:27:58.880 +potential output targets + +0:27:57.279,0:28:01.120 +i think you should just make them as you + +0:27:58.880,0:28:02.559 +go and you know add them as you need + +0:28:01.120,0:28:05.600 +them we'll make uh + +0:28:02.559,0:28:07.840 +help requests or things and uh + +0:28:05.600,0:28:09.279 +we can we can share recipes in this uh + +0:28:07.840,0:28:12.799 +document and then + +0:28:09.279,0:28:16.000 +try to add other uh techniques and then + +0:28:12.799,0:28:19.200 +and we can uh use these blocks as a + +0:28:16.000,0:28:22.240 +common uh interface for + +0:28:19.200,0:28:26.000 +for exporting to pdf and other things + +0:28:22.240,0:28:28.399 +and since someone asked here is a um + +0:28:26.000,0:28:30.159 +here is uh what a pdf looks like this is + +0:28:28.399,0:28:33.840 +the same pdf and + +0:28:30.159,0:28:34.960 +uh rendered uh just i made no effort to + +0:28:33.840,0:28:37.840 +make it look good + +0:28:34.960,0:28:38.559 +but it surprisingly does look good so so + +0:28:37.840,0:28:41.600 +uh that was + +0:28:38.559,0:28:44.320 +uh that was nice um that was a + +0:28:41.600,0:28:44.880 +terrible magenta but that is life uh + +0:28:44.320,0:28:47.279 +anyhow + +0:28:44.880,0:28:48.960 +i hope you all enjoyed this talk i hope + +0:28:47.279,0:28:51.679 +you will find um + +0:28:48.960,0:28:52.799 +death block uh useful to you it is + +0:28:51.679,0:28:54.960

uh + +0:00:03.679,0:00:08.000 +do you think that this package can be + +0:00:05.600,0:00:11.760 +included into emacs or + +0:00:08.000,0:00:11.760 +uh empire uh + +0:00:12.320,0:00:18.560 +i think uh it most definitely can is + +0:00:15.360,0:00:21.760 +just a matter of paperwork but + +0:00:18.560,0:00:24.480 +the reason i initially wanted to make it + +0:00:21.760,0:00:25.039 +like a central package is that so that i + +0:00:24.480,0:00:28.720 +can + +0:00:25.039,0:00:31.920 +experiment with it more + +0:00:28.720,0:00:34.320 +like have more freedom to experiment but + +0:00:31.920,0:00:35.680 +eventually i think is a good candidate + +0:00:34.320,0:00:37.920 +for inclusion into + +0:00:35.680,0:00:37.920 +core + +0:00:38.800,0:00:42.640 +and because because currently not in + +0:00:41.200,0:00:44.480 +corey mass there are a couple of + +0:00:42.640,0:00:47.840 +problems with it + +0:00:44.480,0:00:50.960 +mostly in terms of performance + +0:00:47.840,0:00:53.280 +for example like anytime we want to + +0:00:50.960,0:00:54.160 +access the text in a buffer we need to + +0:00:53.280,0:00:57.360 +make + +0:00:54.160,0:01:00.480 +a copy of the text into a string + +0:00:57.360,0:01:03.520 +and then right after reading from that + +0:01:00.480,0:01:05.280 +text we need to free it right away and + +0:01:03.520,0:01:09.040 +that results in a lot of garbage + +0:01:05.280,0:01:11.920 +collection so it would be better + +0:01:09.040,0:01:12.240 +either the treasure could be included in + +0:01:11.920,0:01:15.680 +core + +0:01:12.240,0:01:16.799 +imax or dynamic dynamic model support + +0:01:15.680,0:01:19.439 +can be + +0:01:16.799,0:01:21.920 +augmented with direct text access + +0:01:19.439,0:01:21.920 +somehow + +0:01:24.080,0:01:27.200 +so the second question is will release + +0:01:26.400,0:01:30.320 +performance + +0:01:27.200,0:01:33.040 +be more competitive with cce max + +0:01:30.320,0:01:35.520 +enough so electricity in english is more + +0:01:33.040,0:01:35.520 +attractive + +0:01:35.670,0:01:43.439 +[Music] + +0:01:38.240,0:01:45.840 +i think it's possible but uh yeah + +0:01:43.439,0:01:46.799 +not sure about the amount of effort it + +0:01:45.840,0:01:52.000 +can be + +0:01:46.799,0:01:52.000 +multi-years effort and one thing that + +0:01:52.960,0:02:00.640 +even though gce max can make uh + +0:01:56.479,0:02:00.640 +it is fast enough there's + +0:02:00.719,0:02:05.280 +there's one thing that it uh cannot have + +0:02:03.119,0:02:09.679 +which is that because it's the lisp + +0:02:05.280,0:02:12.480 +it needs the garage collector so + +0:02:09.679,0:02:14.000 +we may experiment experience some kind + +0:02:12.480,0:02:17.360 +of + +0:02:14.000,0:02:19.920 +gcc post if we use live whereas the + +0:02:17.360,0:02:24.720 +currently transistor is written in c + +0:02:19.920,0:02:24.720 +so there's no such latency + +0:02:28.400,0:02:32.400 +the next question is do you think three + +0:02:31.040,0:02:36.080 +sister would be useful + +0:02:32.400,0:02:38.319 +for all buffers i can imagine it being + +0:02:36.080,0:02:39.599 +used to keep a post ast about an arc + +0:02:38.319,0:02:42.560 +buffer + +0:02:39.599,0:02:43.920 +light off element and update it in real + +0:02:42.560,0:02:46.239 +time + +0:02:43.920,0:02:47.760 +yeah actually this is a very interesting + +0:02:46.239,0:02:50.800 +idea + +0:02:47.760,0:02:53.760 +i saw someone started + +0:02:50.800,0:02:55.120 +resistor grammar for all already i don't + +0:02:53.760,0:02:58.159 +have a link right now but + +0:02:55.120,0:03:01.040 +i can look for it + +0:02:58.159,0:03:01.680 +i'll try looking for it and put the link + +0:03:01.040,0:03:05.840 +in + +0:03:01.680,0:03:05.840 +here later + +0:03:09.599,0:03:15.519 +yeah yes someone has written here the uh + +0:03:13.280,0:03:17.040 +and the biggest problem with uh right + +0:03:15.519,0:03:20.560 +now is that it doesn't have + +0:03:17.040,0:03:20.560 +formal grammar so + +0:03:21.360,0:03:24.400 +so the effort + +0:03:22.380,0:03:27.120 +[Applause] + +0:03:24.400,0:03:28.799 +be quite big i think but but once we + +0:03:27.120,0:03:31.519 +have that because the + +0:03:28.799,0:03:33.840 +tree sitter can be run on the web as + +0:03:31.519,0:03:33.840 +well + +0:03:34.239,0:03:38.080 +we can on the web and in many other + +0:03:37.440,0:03:40.720 +places + +0:03:38.080,0:03:41.840 +if we have a grammar for a traditional + +0:03:40.720,0:03:45.680 +grammar for all + +0:03:41.840,0:03:49.680 +we can bring off more + +0:03:45.680,0:03:52.000 +like everywhere that's a very cool + +0:03:49.680,0:03:52.000 +thought + +0:03:56.000,0:04:00.480 +next one is could this be used with + +0:03:58.080,0:04:03.200 +packages like smart parents that aim to + +0:04:00.480,0:04:07.120 +bring structural editing to + +0:04:03.200,0:04:11.360 +non-s expression based languages + +0:04:07.120,0:04:14.720 +yes that is actually one of the + +0:04:11.360,0:04:17.280 +intended use cases initially + +0:04:14.720,0:04:18.880 +it's definitely possible but it's just + +0:04:17.280,0:04:29.840 +that no one has + +0:04:18.880,0:04:29.840 +only started writing the integration yet + +0:04:37.199,0:04:41.919 +and next one + +0:04:40.639,0:04:45.040 +could you show the source that was + +0:04:41.919,0:04:48.479 +matched by the parser in the debug view + +0:04:45.040,0:04:53.440 +in addition to the grammar part matched + +0:04:48.479,0:04:53.440 +uh yeah that's actually um + +0:04:54.960,0:04:59.280 +on my to-do list but i haven't had time + +0:04:57.759,0:05:02.560 +for it yet + +0:04:59.280,0:05:06.560 +so uh if you go to the treesita + +0:05:02.560,0:05:08.800 +website it also has an + +0:05:06.560,0:05:11.840 +online playground where you can input + +0:05:08.800,0:05:11.840 +the code and see the + +0:05:12.000,0:05:16.000 +parse tree in real time and it's + +0:05:14.400,0:05:19.360 +actually + +0:05:16.000,0:05:22.840 +a lot more fancy than what we have in + +0:05:19.360,0:05:25.919 +imax currently so + +0:05:22.840,0:05:27.120 +yeah i just don't have time for it yes + +0:05:25.919,0:05:30.240 +so + +0:05:27.120,0:05:30.240 +some help here would be + +0:05:30.320,0:05:41.730 +very appreciated + +0:05:38.700,0:05:41.730 +[Music] + +0:05:49.919,0:05:54.240 +the next question is will it ever be + +0:05:52.000,0:05:55.280 +possible to write resetter grammars in a + +0:05:54.240,0:05:59.520 +lisp + +0:05:55.280,0:05:59.520 +or will javascript be required + +0:06:00.560,0:06:05.280 +yeah that is already answered in the + +0:06:02.800,0:06:07.600 +part so the + +0:06:05.280,0:06:08.639 +the transcript is actually just used as + +0:06:07.600,0:06:12.160 +a sort of + +0:06:08.639,0:06:14.639 +preprocessor so the + +0:06:12.160,0:06:15.680 +python generator actually works on the + +0:06:14.639,0:06:19.280 +on a json + +0:06:15.680,0:06:20.240 +structure so uh it's definitely possible + +0:06:19.280,0:06:24.240 +to replace + +0:06:20.240,0:06:24.240 +javascript with lists for this + +0:06:29.039,0:06:32.160 +how extensive will the compatibility + +0:06:31.280,0:06:35.360 +between + +0:06:32.160,0:06:35.840 +highlighting grammars for e-max and + +0:06:35.360,0:06:41.039 +those + +0:06:35.840,0:06:41.039 +for veeam nail view + +0:06:44.560,0:06:51.680 +so so right now the + +0:06:48.720,0:06:52.000 +nail vim and emacs used a different set + +0:06:51.680,0:06:55.440 +of + +0:06:52.000,0:06:59.520 +the highlighting queries and + +0:06:55.440,0:07:03.039 +item probably uses another set of + +0:06:59.520,0:07:04.960 +patterns as well i think it makes sense + +0:07:03.039,0:07:07.680 +because + +0:07:04.960,0:07:08.479 +each editor has its own like existing + +0:07:07.680,0:07:11.919 +conventions + +0:07:08.479,0:07:15.599 +for syntax highlighting so + +0:07:11.919,0:07:18.560 +at least in the beginning i don't expect + +0:07:15.599,0:07:21.520 +there is any compatibility between + +0:07:18.560,0:07:21.520 +different editors + +0:07:21.599,0:07:26.639 +but i think in the long run it will be + +0:07:27.280,0:07:31.360 +would it better if there's some kind of + +0:07:29.520,0:07:34.880 +effort to + +0:07:31.360,0:07:37.440 +unify the at least provide the + +0:07:34.880,0:07:39.759 +most common patterns that should work + +0:07:37.440,0:07:39.759 +across + +0:07:42.840,0:07:45.840 +editors + +0:07:51.759,0:07:55.280 +next one is could there be a + +0:07:53.520,0:07:57.919 +standardized approach + +0:07:55.280,0:08:00.319 +to coding automatic refactoring in the + +0:07:57.919,0:08:00.319 +future + +0:08:01.039,0:08:04.160 +so that whichever language mode you're + +0:08:02.639,0:08:12.960 +using you could see many + +0:08:04.160,0:08:16.400 +available refactoring operations + +0:08:12.960,0:08:18.639 +i'm not sure about this because the + +0:08:16.400,0:08:18.639 +like + +0:08:19.919,0:08:23.840 +most of uh refactoring operations are + +0:08:22.240,0:08:26.960 +actually very + +0:08:23.840,0:08:28.720 +like highly specific to a language or at + +0:08:26.960,0:08:32.800 +least to class of + +0:08:28.720,0:08:32.800 +class of languages so + +0:08:33.599,0:08:40.719 +so so maybe it's not like uh one single + +0:08:37.839,0:08:41.519 +approach for all the languages but maybe + +0:08:40.719,0:08:43.760 +uh + +0:08:41.519,0:08:44.959 +one for object-oriented oriented + +0:08:43.760,0:08:49.920 +languages + +0:08:44.959,0:08:49.920 +one for lisp like language for example + +0:08:50.160,0:08:55.839 +maybe one for javascript and typestream + +0:09:02.959,0:09:07.519 +next question is uh i'm completely new + +0:09:05.360,0:09:10.160 +to trisita how do i use it + +0:09:07.519,0:09:11.519 +as an end user is there any easy example + +0:09:10.160,0:09:14.000 +config out there + +0:09:11.519,0:09:15.440 +the organizer otherwise that shows + +0:09:14.000,0:09:18.959 +standard usage + +0:09:15.440,0:09:18.959 +with whatever programming language + +0:09:18.960,0:09:23.920 +[Music] + +0:09:20.480,0:09:23.920 +yeah there's no um + +0:09:27.600,0:09:32.000 +uh actually that uh so the project has + +0:09:30.880,0:09:36.399 +the documentation + +0:09:32.000,0:09:40.720 +site but it's not very expensive yet + +0:09:36.399,0:09:44.000 +i think we need to add more examples + +0:09:40.720,0:09:44.000 +to the documentation + +0:09:48.720,0:09:53.519 +can language major mode authors start + +0:09:51.200,0:09:56.240 +taking advantage of this now + +0:09:53.519,0:09:57.279 +or is it intended to be used as a minor + +0:09:56.240,0:10:00.399 +mode + +0:09:57.279,0:10:01.600 +uh actually it's both so it's intended + +0:10:00.399,0:10:04.480 +to be used + +0:10:01.600,0:10:05.920 +as a minor mode but it's also intended + +0:10:04.480,0:10:09.839 +to + +0:10:05.920,0:10:13.519 +be depended on by the major mode + +0:10:09.839,0:10:13.920 +so basically it it wants to be a minor + +0:10:13.519,0:10:17.200 +mode + +0:10:13.920,0:10:19.839 +that is dependent on by the other + +0:10:17.200,0:10:19.839 +major modes + +0:10:21.839,0:10:29.279 +and by it here i mean the the base + +0:10:25.680,0:10:29.279 +minor mode tree system mode + +0:10:30.839,0:10:37.120 +so uh question + +0:10:34.079,0:10:40.160 +11 is it possible to use this + +0:10:37.120,0:10:43.360 +for refactoring tool + +0:10:40.160,0:10:46.720 +uh yeah but + +0:10:43.360,0:10:47.680 +um like for the kind of refactoring + +0:10:46.720,0:10:52.079 +inside uh + +0:10:47.680,0:10:52.079 +buffer it is uh + +0:10:52.640,0:10:57.040 +it's very doable right now but you need + +0:10:55.040,0:11:01.120 +to write some glue code + +0:10:57.040,0:11:04.000 +but for for the kind of more + +0:11:01.120,0:11:04.399 +extensive refactoring where you want to + +0:11:04.000,0:11:09.120 +touch + +0:11:04.399,0:11:09.120 +uh like all files in a project + +0:11:09.279,0:11:12.839 +there needs there needs to be some kind + +0:11:11.440,0:11:15.920 +of the project + +0:11:12.839,0:11:18.399 +and another project and uh + +0:11:15.920,0:11:19.200 +understanding of the language uh model + +0:11:18.399,0:11:21.120 +system + +0:11:19.200,0:11:22.560 +like how they are laid out in the file + +0:11:21.120,0:11:24.480 +system as well + +0:11:22.560,0:11:26.240 +and with that understanding that there + +0:11:24.480,0:11:29.920 +should be passing of + +0:11:26.240,0:11:30.480 +the files even files on the file system + +0:11:29.920,0:11:34.000 +that + +0:11:30.480,0:11:37.760 +are not yet loaded into emacs + +0:11:34.000,0:11:40.320 +so that sounds like something more + +0:11:37.760,0:11:40.320 +a lot more + +0:11:41.040,0:11:44.560 +a lot more extensive + +0:11:46.320,0:11:50.000 +and it probably probably sounds like + +0:11:49.519,0:11:52.160 +something + +0:11:50.000,0:11:54.560 +something like an id in uh inside your + +0:11:52.160,0:11:57.839 +max already like a replacement for + +0:11:54.560,0:11:57.839 +for lsp + +0:12:07.360,0:12:11.440 +so next question is the that pop-up mx + +0:12:10.480,0:12:14.480 +window + +0:12:11.440,0:12:14.480 +how do you get that + +0:12:15.200,0:12:20.320 +is the custom hem code i wrote a long + +0:12:18.720,0:12:24.800 +time ago + +0:12:20.320,0:12:26.480 +but but right now the best way to + +0:12:24.800,0:12:29.440 +to have something like that is probably + +0:12:26.480,0:12:33.200 +the what is written here like uh + +0:12:29.440,0:12:39.839 +ham boss frame or iv spring + +0:12:33.200,0:12:43.680 +is a lot easier now + +0:12:39.839,0:12:46.320 +is there a folding mode for tree sitter + +0:12:43.680,0:12:48.079 +nowadays there's no folding mode for + +0:12:46.320,0:12:52.000 +three sitters yet + +0:12:48.079,0:12:54.880 +but uh + +0:12:52.000,0:12:58.720 +uh but i think it would better be better + +0:12:54.880,0:12:58.720 +if it's integrated with the + +0:12:59.440,0:13:03.120 +like current currently there are + +0:13:02.079,0:13:04.880 +multiple + +0:13:03.120,0:13:07.200 +i'm not sure they're moving forward + +0:13:04.880,0:13:10.240 +there are like code folding frameworks + +0:13:07.200,0:13:12.800 +inside imax already or some the + +0:13:10.240,0:13:13.920 +code showing packages like third party + +0:13:12.800,0:13:15.680 +packaging + +0:13:13.920,0:13:17.680 +and i think it's better to integrate + +0:13:15.680,0:13:20.000 +with these mods + +0:13:17.680,0:13:22.560 +rather than writing something new + +0:13:20.000,0:13:22.560 +entirely + +0:13:32.399,0:13:36.639 +are there any language major modes that + +0:13:34.800,0:13:40.079 +have integrated already + +0:13:36.639,0:13:42.800 +uh not yet + +0:13:40.079,0:13:43.440 +so the there was a proposed web assembly + +0:13:42.800,0:13:46.839 +mode + +0:13:43.440,0:13:50.000 +but it's a new major mode in terms of + +0:13:46.839,0:13:52.880 +existing major mode there is the + +0:13:50.000,0:13:52.880 +typescript mode + +0:13:53.279,0:13:57.519 +but they're only discussing about + +0:13:55.600,0:14:02.079 +integration + +0:13:57.519,0:14:04.639 +they're not integrated yet + +0:14:02.079,0:14:05.360 +i think i can try writing the + +0:14:04.639,0:14:09.199 +integration + +0:14:05.360,0:14:11.839 +sometimes next month + +0:14:09.199,0:14:12.720 +uh basically what they want right now is + +0:14:11.839,0:14:16.160 +the + +0:14:12.720,0:14:19.199 +syntax highlighting and handling + +0:14:16.160,0:14:22.959 +synthetic highlighting and + +0:14:19.199,0:14:27.760 +code indentation for tsx + +0:14:22.959,0:14:31.839 +which is the embedded react + +0:14:27.760,0:14:31.839 +syntax inside typescript + +0:14:32.160,0:14:40.000 +so it turns out passing these tests + +0:14:36.399,0:14:40.000 +is very troublesome so + +0:14:40.639,0:14:47.040 +so trees that would be a crystal would + +0:14:43.920,0:14:47.040 +be a lot of help there + +0:14:49.920,0:14:59.839 +is there any link to the slides yes + +0:14:53.279,0:14:59.839 +i'll post it in irc later + +0:14:59.920,0:15:04.240 +regarding imax integration we will + +0:15:01.920,0:15:05.440 +always need to be a foreign library or + +0:15:04.240,0:15:09.920 +can it be included + +0:15:05.440,0:15:09.920 +linked directly in compilation + +0:15:10.839,0:15:17.600 +uh if if this is about the + +0:15:14.480,0:15:21.839 +core library itself + +0:15:17.600,0:15:23.440 +then i think it's uh answered it in the + +0:15:21.839,0:15:27.440 +first question + +0:15:23.440,0:15:29.920 +right now is a right now it's a + +0:15:27.440,0:15:30.959 +dynamic model but in the long run it + +0:15:29.920,0:15:34.000 +will better if + +0:15:30.959,0:15:39.839 +it's included in core emacs + +0:15:34.000,0:15:41.360 +for the language definitions themselves + +0:15:39.839,0:15:43.279 +it should be better if they are + +0:15:41.360,0:15:46.639 +distributed uh + +0:15:43.279,0:15:49.199 +separately like that right now so each + +0:15:46.639,0:15:49.680 +uh for each language there will be a + +0:15:49.199,0:15:52.639 +shared + +0:15:49.680,0:15:55.839 +library that will be loaded by the core + +0:15:52.639,0:15:55.839 +library at runtime + +0:16:00.480,0:16:04.240 +so the last question is the python mode + +0:16:02.480,0:16:06.160 +example is pretty good + +0:16:04.240,0:16:07.600 +is that something that one can use + +0:16:06.160,0:16:11.759 +already + +0:16:07.600,0:16:11.759 +yes i'm using it at work right now + +0:16:12.320,0:16:17.360 +i think that's all for that's all the + +0:16:14.639,0:16:17.360 +questions right + +0:16:19.199,0:16:27.839 +you are now unmuted yeah i think that's + +0:16:23.440,0:16:30.399 +all the questions on the pads so far um + +0:16:27.839,0:16:32.399 +so thank you but um there may be more + +0:16:30.399,0:16:36.639 +questions coming on irc + +0:16:32.399,0:16:39.680 +um i'll try to have a look + +0:16:36.639,0:16:40.560 +and we still have about 10 or 15 more + +0:16:39.680,0:16:43.600 +minutes so + +0:16:40.560,0:16:46.880 +um there's no rush to wrap up in case um + +0:16:43.600,0:16:46.880 +anyone has any more questions + +0:16:48.160,0:16:51.360 +uh yeah i just realized that uh i mixed + +0:16:50.880,0:16:54.959 +up the + +0:16:51.360,0:16:56.000 +video editing and i uh lost an entire + +0:16:54.959,0:17:00.880 +session on the + +0:16:56.000,0:17:00.880 +introduction to treesita oh + +0:17:01.120,0:17:05.839 +no worries + +0:17:06.640,0:17:20.079 +you are now muted + +0:17:18.079,0:17:21.679 +sounds like a perfect opportunity for + +0:17:20.079,0:17:24.000 +you to redo the introduction if you'd + +0:17:21.679,0:17:24.000 +like to + +0:17:24.640,0:17:30.000 +uh actually uh forgot a lot of that + +0:17:30.799,0:17:35.760 +and i'm with uh tired now so no i don't + +0:17:33.760,0:17:39.200 +think i can do it + +0:17:35.760,0:17:43.520 +it's uh 30 minutes until my bedtime + +0:17:39.200,0:17:46.640 +oh yeah yeah okay you are now unmuted + +0:17:43.520,0:17:50.480 +so in that case maybe we should + +0:17:46.640,0:17:54.240 +um we should let tona + +0:17:50.480,0:17:56.960 +get started going to bed and um and + +0:17:54.240,0:17:57.840 +i mean then i will figure out what to do + +0:17:56.960,0:17:59.360 +with the time + +0:17:57.840,0:18:02.160 +should we start the next talk early + +0:17:59.360,0:18:05.360 +since it's pre-recorded + +0:18:02.160,0:18:07.919 +um yeah we can do we can do that um + +0:18:05.360,0:18:09.919 +but um yeah tonight it you know right + +0:18:07.919,0:18:10.480 +now it's pretty late there um no worries + +0:18:09.919,0:18:12.720 +but + +0:18:10.480,0:18:13.520 +yeah if you know over the next few days + +0:18:12.720,0:18:16.559 +or weeks + +0:18:13.520,0:18:20.240 +if you would like to um you know + +0:18:16.559,0:18:22.080 +do a quick pre-recording or recording + +0:18:20.240,0:18:24.320 +to add the introduction and then stitch + +0:18:22.080,0:18:26.559 +it in with what you had already sent me + +0:18:24.320,0:18:30.160 +um by all means please do that and i + +0:18:26.559,0:18:33.760 +will upload the edited version + +0:18:30.160,0:18:33.760 +uh yeah yeah i'll try to do that +

to support programming + +0:00:23.359,0:00:25.760 +functionalities for a particular + +0:00:24.960,0:00:27.680 +language + +0:00:25.760,0:00:29.679 +a text editor needs to have some degree + +0:00:27.680,0:00:31.840 +of language understanding + +0:00:29.679,0:00:33.840 +traditionally text editors have relied + +0:00:31.840,0:00:34.960 +very heavily on regular expressions for +

+problematic for a couple of reasons + +0:00:50.559,0:00:54.000 +they're slow and inaccurate they also + +0:00:53.600,0:00:56.800 +make + +0:00:54.000,0:00:57.440 +the code hard to read and write + +0:00:56.800,0:00:59.199 +sometimes + +0:00:57.440,0:01:01.199 +it's because the regular expressions + +0:00:59.199,0:01:04.000 +themselves are very hairy + +0:01:01.199,0:01:05.199 +and sometimes because they are just not + +0:01:04.000,0:01:07.840 +powerful enough + +0:01:05.199,0:01:11.200 +some helper code is usually needed to + +0:01:07.840,0:01:13.280 +pass more intricate language features + +0:01:11.200,0:01:16.159 +that also illustrates the core problem + +0:01:13.280,0:01:18.400 +with regular expressions + +0:01:16.159,0:01:21.119 +in that they are not powerful enough to + +0:01:18.400,0:01:22.640 +pass programming languages + +0:01:21.119,0:01:25.040 +an example feature that regular + +0:01:22.640,0:01:27.520 +expressions cannot handle very well + +0:01:25.040,0:01:28.320 +is string interpolation which is a very + +0:01:27.520,0:01:31.680 +common feature + +0:01:28.320,0:01:34.079 +in many modern programming languages + +0:01:31.680,0:01:35.840 +it would be much nicer if image somehow + +0:01:34.079,0:01:36.479 +had structural understanding of source + +0:01:35.840,0:01:39.439 +code + +0:01:36.479,0:01:39.439 +like ides do + +0:01:39.520,0:01:42.960 +there have been multiple efforts to + +0:01:41.119,0:01:45.280 +bring this kind of programming language + +0:01:42.960,0:01:47.119 +understanding into emacs + +0:01:45.280,0:01:48.640 +there are language specific persons + +0:01:47.119,0:01:50.240 +written in elise + +0:01:48.640,0:01:52.320 +they can be thought of as the next + +0:01:50.240,0:01:54.960 +logical step of the glue code on top + +0:01:52.320,0:01:56.000 +of tribal expressions moving from + +0:01:54.960,0:01:58.079 +partial local + +0:01:56.000,0:01:59.840 +pattern recognition into a full-fledged + +0:01:58.079,0:02:01.439 +parser + +0:01:59.840,0:02:03.040 +the most prominent example of this + +0:02:01.439,0:02:06.159 +approach is probably the famous + +0:02:03.040,0:02:06.159 +js2 mode + +0:02:06.479,0:02:12.959 +however this approach has several issues + +0:02:10.080,0:02:13.680 +parsing is computationally expensive and + +0:02:12.959,0:02:16.800 +imagine + +0:02:13.680,0:02:18.400 +is not good at that kind of stuff + +0:02:16.800,0:02:20.840 +furthermore maintenance is very + +0:02:18.400,0:02:22.160 +troublesome in order to work on these + +0:02:20.840,0:02:23.599 +process + +0:02:22.160,0:02:25.599 +first you have to know at least well + +0:02:23.599,0:02:27.760 +enough and then you have to be + +0:02:25.599,0:02:30.319 +comfortable with writing a + +0:02:27.760,0:02:32.080 +recursive ascendant parser while + +0:02:30.319,0:02:34.000 +constantly keeping up with changes to + +0:02:32.080,0:02:36.879 +the language itself + +0:02:34.000,0:02:39.360 +which can be evolving very quickly like + +0:02:36.879,0:02:41.599 +javascript for example + +0:02:39.360,0:02:45.680 +together these constraints significantly + +0:02:41.599,0:02:47.760 +reduce the pull of potential maintenance + +0:02:45.680,0:02:49.680 +the biggest issue though in my opinion + +0:02:47.760,0:02:52.879 +is lack of the set of generic + +0:02:49.680,0:02:54.319 +and reusable apis this makes them very + +0:02:52.879,0:02:55.920 +hard to use + +0:02:54.319,0:02:57.920 +for minor modes that want to deal with + +0:02:55.920,0:02:59.920 +cross-cutting concerns across multiple + +0:02:57.920,0:03:01.760 +languages + +0:02:59.920,0:03:03.599 +the other approach which has been + +0:03:01.760,0:03:04.319 +gaining a lot of momentum in recent + +0:03:03.599,0:03:06.560 +years + +0:03:04.319,0:03:08.159 +is externalizing language understanding + +0:03:06.560,0:03:12.239 +to another process + +0:03:08.159,0:03:14.480 +also known as language server protocol + +0:03:12.239,0:03:16.560 +this second approach is actually a very + +0:03:14.480,0:03:18.400 +interesting one + +0:03:16.560,0:03:21.280 +my decoupling language understanding + +0:03:18.400,0:03:23.760 +from the editing facility itself + +0:03:21.280,0:03:25.120 +the usb servers can attract a lot more + +0:03:23.760,0:03:28.959 +contributors + +0:03:25.120,0:03:32.400 +which makes maintenance easier however + +0:03:28.959,0:03:34.720 +they also have several issues available + +0:03:32.400,0:03:36.000 +being a separate process they are + +0:03:34.720,0:03:39.920 +usually more resource + +0:03:36.000,0:03:42.159 +intensive and depending on the language + +0:03:39.920,0:03:44.640 +the usb server itself can bring with it + +0:03:42.159,0:03:47.680 +a host of additional dependencies + +0:03:44.640,0:03:50.560 +external to emacs which may message to + +0:03:47.680,0:03:50.560 +install and manage + +0:03:50.640,0:03:55.120 +furthermore json over rpc has pretty + +0:03:53.760,0:03:57.840 +high latency + +0:03:55.120,0:04:00.879 +for one-off tasks like jumping to source + +0:03:57.840,0:04:03.040 +or on-demand completion is great + +0:04:00.879,0:04:06.000 +but for things like code highlighting + +0:04:03.040,0:04:08.319 +the latency is just too much + +0:04:06.000,0:04:10.480 +i was using rust and i was following the + +0:04:08.319,0:04:11.760 +community effort to improve its id + +0:04:10.480,0:04:13.680 +support + +0:04:11.760,0:04:15.760 +hoping to integrate some of that into + +0:04:13.680,0:04:17.600 +emacs itself + +0:04:15.760,0:04:19.759 +then i heard someone from community + +0:04:17.600,0:04:23.280 +mention tree sitter + +0:04:19.759,0:04:23.280 +and i decided to check it out + +0:04:23.360,0:04:28.720 +basically trisita is an incremental + +0:04:25.520,0:04:31.000 +parsing library and a parser generator + +0:04:28.720,0:04:33.040 +it was introduced by the item editor in + +0:04:31.000,0:04:35.680 +2018 + +0:04:33.040,0:04:36.960 +besides item is also being integrated + +0:04:35.680,0:04:41.040 +into the neo-vim + +0:04:36.960,0:04:42.479 +editor and github is using it to power + +0:04:41.040,0:04:45.600 +their source code analysis and + +0:04:42.479,0:04:45.600 +navigation features + +0:04:45.840,0:04:49.199 +it is written in c and can be compiled + +0:04:48.639,0:04:53.120 +for all + +0:04:49.199,0:04:56.080 +major platforms it can even be compiled + +0:04:53.120,0:04:57.600 +to web assembly to run on the web that's + +0:04:56.080,0:05:00.400 +how github is using it + +0:04:57.600,0:05:00.400 +on their website + +0:05:00.800,0:05:05.840 +so why is trisita an interesting + +0:05:02.960,0:05:07.360 +solution to this problem + +0:05:05.840,0:05:10.000 +there are multiple features that make it + +0:05:07.360,0:05:12.400 +an attractive option + +0:05:10.000,0:05:13.680 +it is designed to be fast by being + +0:05:12.400,0:05:15.680 +incremental + +0:05:13.680,0:05:18.160 +the initial parts of a typical big fight + +0:05:15.680,0:05:20.240 +can take tens of milliseconds + +0:05:18.160,0:05:22.560 +while subsequent incremental processes + +0:05:20.240,0:05:24.720 +are sub milliseconds + +0:05:22.560,0:05:26.240 +it achieves this by using structural + +0:05:24.720,0:05:29.360 +sharing + +0:05:26.240,0:05:32.960 +meaning replacing only affected nodes + +0:05:29.360,0:05:36.000 +in the old tree when it needs to + +0:05:32.960,0:05:37.120 +also unlike lsp being in the same + +0:05:36.000,0:05:40.639 +process + +0:05:37.120,0:05:42.880 +it has much lower latency + +0:05:40.639,0:05:44.960 +secondly it provides a uniform + +0:05:42.880,0:05:47.039 +programming interface + +0:05:44.960,0:05:48.720 +the same data structures and functions + +0:05:47.039,0:05:50.400 +work on parse trees of different + +0:05:48.720,0:05:52.160 +languages + +0:05:50.400,0:05:54.160 +syntax knows of different languages + +0:05:52.160,0:05:57.360 +differ only by their types + +0:05:54.160,0:05:58.960 +and their possible child nodes this + +0:05:57.360,0:06:02.000 +is a big advantage over language + +0:05:58.960,0:06:02.000 +specific parcels + +0:06:02.240,0:06:06.880 +thirdly it's written in self-contained + +0:06:04.880,0:06:09.680 +embeddable c + +0:06:06.880,0:06:10.400 +as i mentioned previously it can even be + +0:06:09.680,0:06:13.759 +compiled + +0:06:10.400,0:06:15.199 +to webassembly this makes integrating it + +0:06:13.759,0:06:18.240 +into various editors + +0:06:15.199,0:06:21.840 +quite easy without having to install + +0:06:18.240,0:06:21.840 +any external dependencies + +0:06:22.880,0:06:28.000 +one thing that is not mentioned here is + +0:06:24.639,0:06:31.039 +that being a parcel generator + +0:06:28.000,0:06:34.880 +scrummers are declarative + +0:06:31.039,0:06:36.720 +together with being editor independent + +0:06:34.880,0:06:38.160 +this makes the pool of potential + +0:06:36.720,0:06:42.400 +contributors + +0:06:38.160,0:06:45.520 +much larger so i was convinced + +0:06:42.400,0:06:48.000 +that trisito is a good fit for emacs + +0:06:45.520,0:06:48.720 +last year i started writing the bindings + +0:06:48.000,0:06:50.960 +using + +0:06:48.720,0:06:53.280 +dynamic model support introduced in imax + +0:06:50.960,0:06:55.360 +25. + +0:06:53.280,0:06:58.479 +dynamic module means there is platform + +0:06:55.360,0:07:00.560 +specific native code involved + +0:06:58.479,0:07:02.880 +but since they are pre-compiled binaries + +0:07:00.560,0:07:06.319 +for the three major platforms + +0:07:02.880,0:07:08.319 +it should work in most places currently + +0:07:06.319,0:07:09.440 +the core functionalities are in a pretty + +0:07:08.319,0:07:12.560 +good shape + +0:07:09.440,0:07:14.840 +syntax highlighting is working nicely + +0:07:12.560,0:07:16.080 +the whole thing is split into three + +0:07:14.840,0:07:17.759 +packages + +0:07:16.080,0:07:20.319 +tree sitter is the main package that + +0:07:17.759,0:07:22.800 +other packages should depend on + +0:07:20.319,0:07:24.000 +tree system lens is the language bundle + +0:07:22.800,0:07:27.199 +that includes support + +0:07:24.000,0:07:30.080 +for most common languages + +0:07:27.199,0:07:32.160 +and finally the core apis are in the + +0:07:30.080,0:07:36.160 +package tsc + +0:07:32.160,0:07:38.800 +which stands for trees the core + +0:07:36.160,0:07:41.919 +it is the implicit dependency of the + +0:07:38.800,0:07:41.919 +three-seater package + +0:07:43.520,0:07:47.520 +the main package includes the miner mode + +0:07:46.000,0:07:49.840 +3-seater mode + +0:07:47.520,0:07:52.560 +this provides the base for other major + +0:07:49.840,0:07:55.280 +or minor modes to build on + +0:07:52.560,0:07:55.840 +using image change tracking hooks it + +0:07:55.280,0:07:58.080 +enables + +0:07:55.840,0:08:00.800 +incremental parsing and provides a + +0:07:58.080,0:08:04.080 +syntax tree that is always up to date + +0:08:00.800,0:08:06.560 +after any edits in a buffer + +0:08:04.080,0:08:10.080 +there is also a basic debug mode that + +0:08:06.560,0:08:13.360 +shows the parse tree in another buffer + +0:08:10.080,0:08:15.759 +here is a quick demo + +0:08:13.360,0:08:17.520 +here i mean an empty python buffer with + +0:08:15.759,0:08:19.440 +three seater enabled + +0:08:17.520,0:08:26.560 +i'm going to turn on the debug mode to + +0:08:19.440,0:08:28.720 +see the parse tree + +0:08:26.560,0:08:30.639 +since the buffer is empty there is only + +0:08:28.720,0:08:33.279 +one node in the syntax tree the top + +0:08:30.639,0:08:41.839 +level module node + +0:08:33.279,0:08:41.839 +let's try typing some code + +0:09:11.040,0:09:14.640 +as you can see as i type into the python + +0:09:13.600,0:09:19.120 +buffer + +0:09:14.640,0:09:21.120 +the syntax tree updates in real time + +0:09:19.120,0:09:23.279 +the other minor mode included in the + +0:09:21.120,0:09:26.640 +main package is 3-seater + +0:09:23.279,0:09:28.480 +hl mode it overrides font-lock mode and + +0:09:26.640,0:09:31.839 +provides its own set of phases + +0:09:28.480,0:09:32.800 +and customization options it is query + +0:09:31.839,0:09:35.200 +driven + +0:09:32.800,0:09:36.240 +that means instead of regular + +0:09:35.200,0:09:38.720 +expressions + +0:09:36.240,0:09:40.320 +it uses a list like query language to + +0:09:38.720,0:09:43.760 +map syntax notes + +0:09:40.320,0:09:45.760 +to highlighting phrases i'm going to + +0:09:43.760,0:09:51.839 +open a python file with small snippets + +0:09:45.760,0:09:51.839 +that showcase syntax highlighting + +0:09:54.320,0:09:59.279 +so this is the default highlighting + +0:09:55.920,0:09:59.279 +provided by python mode + +0:10:00.880,0:10:04.640 +this is the highlighting enabled by tree + +0:10:02.839,0:10:07.680 +sitter + +0:10:04.640,0:10:11.680 +as you can see string interpolation + +0:10:07.680,0:10:15.440 +and decorators are highlighted correctly + +0:10:11.680,0:10:15.440 +function calls are also highlighted + +0:10:17.440,0:10:21.839 +you can also note that property + +0:10:20.240,0:10:24.640 +assessors + +0:10:21.839,0:10:27.200 +and property assignments are highlighted + +0:10:24.640,0:10:27.200 +differently + +0:10:27.440,0:10:30.880 +what i like the most about this is that + +0:10:29.360,0:10:32.640 +new bindings are consistently + +0:10:30.880,0:10:36.320 +highlighted + +0:10:32.640,0:10:39.760 +this included local variable + +0:10:36.320,0:10:42.480 +function parameters and property + +0:10:39.760,0:10:42.480 +mutations + +0:10:45.760,0:10:49.279 +before going through the three queries + +0:10:48.000,0:10:51.680 +and the syntax highlighting + +0:10:49.279,0:10:53.760 +customization options + +0:10:51.680,0:10:55.040 +let's take a brief look at the core data + +0:10:53.760,0:10:58.079 +structures and functions + +0:10:55.040,0:10:59.839 +that tree sitter provides + +0:10:58.079,0:11:02.240 +so parsing is done with the help of a + +0:10:59.839,0:11:04.160 +generic parser object + +0:11:02.240,0:11:06.000 +a single parser object can be used to + +0:11:04.160,0:11:08.320 +pass different languages + +0:11:06.000,0:11:09.279 +by sending different language objects to + +0:11:08.320,0:11:10.880 +it + +0:11:09.279,0:11:14.079 +the language objects themselves are + +0:11:10.880,0:11:16.079 +loaded from shared libraries + +0:11:14.079,0:11:17.360 +since three seater mode already handles + +0:11:16.079,0:11:19.440 +the parsing part + +0:11:17.360,0:11:20.800 +we will instead focus on the functions + +0:11:19.440,0:11:24.720 +that inspect nodes + +0:11:20.800,0:11:24.720 +and in the resulting path tree + +0:11:25.279,0:11:43.839 +we can ask tree sitter what is the + +0:11:27.200,0:11:43.839 +syntax node at point + +0:11:44.240,0:11:48.480 +uh is it an opaque object so this is not + +0:11:47.200,0:11:57.839 +very useful + +0:11:48.480,0:11:57.839 +we can instead ask what is its type + +0:12:03.760,0:12:08.959 +so his type is the symbol comparison + +0:12:06.560,0:12:11.600 +operator + +0:12:08.959,0:12:13.680 +trees there are two kinds of nodes + +0:12:11.600,0:12:15.519 +anonymous nodes and named nodes + +0:12:13.680,0:12:17.040 +anonymous nodes correspond to simple + +0:12:15.519,0:12:19.839 +grammar elements + +0:12:17.040,0:12:21.279 +like keywords operators punctuations and + +0:12:19.839,0:12:24.160 +so on + +0:12:21.279,0:12:25.920 +name nodes on the other hand grammar + +0:12:24.160,0:12:26.639 +elements that are interesting enough for + +0:12:25.920,0:12:30.320 +their own + +0:12:26.639,0:12:31.839 +to have a name like an identifier an + +0:12:30.320,0:12:35.200 +expression + +0:12:31.839,0:12:35.200 +or a function definition + +0:12:35.440,0:12:41.519 +name node types are symbols while + +0:12:37.760,0:12:41.519 +anonymous node types are strings + +0:12:42.639,0:12:49.519 +for example if we are on this + +0:12:46.320,0:12:49.519 +comparison operator + +0:12:49.760,0:12:53.839 +the node type should be a string + +0:12:55.920,0:12:58.959 +we can also get other information about + +0:12:57.920,0:13:07.839 +the node + +0:12:58.959,0:13:07.839 +for example what is this text + +0:13:09.680,0:13:35.839 +or where it is in the buffer + +0:13:20.800,0:13:35.839 +or what is its parent + +0:13:43.199,0:13:46.839 +there are many other apis to query or + +0:13:46.160,0:13:49.839 +not + +0:13:46.839,0:13:49.839 +properties + +0:13:52.639,0:13:58.240 +tree sitter allows searching for + +0:13:54.399,0:14:01.440 +structural patterns within a parse tree + +0:13:58.240,0:14:03.519 +it does so through a list like language + +0:14:01.440,0:14:04.639 +this language supports by the matching + +0:14:03.519,0:14:07.760 +by node types + +0:14:04.639,0:14:10.079 +field names and predicates + +0:14:07.760,0:14:12.639 +it also allows capturing nodes for + +0:14:10.079,0:14:17.839 +further processing + +0:14:12.639,0:14:17.839 +let's try to see some examples + +0:14:37.680,0:14:43.839 +so in this very simple query we just + +0:14:41.040,0:14:46.399 +try to highlight all the identifiers in + +0:14:43.839,0:14:46.399 +the buffer + +0:14:49.040,0:14:53.120 +this s side tells trisito to capture a + +0:14:51.920,0:14:55.839 +node + +0:14:53.120,0:14:57.360 +in the context of the query builder it's + +0:14:55.839,0:15:00.320 +not very important + +0:14:57.360,0:15:01.760 +but in normal highlighting query this + +0:15:00.320,0:15:05.920 +will determine + +0:15:01.760,0:15:05.920 +the face used to highlight the note + +0:15:06.639,0:15:10.320 +suppose we want to capture all the + +0:15:08.800,0:15:13.519 +function names + +0:15:10.320,0:15:27.839 +instead of just any identifier + +0:15:13.519,0:15:27.839 +you can improve the query like this + +0:15:29.440,0:15:32.639 +uh this will highlight the whole + +0:15:31.600,0:15:35.519 +definition + +0:15:32.639,0:15:36.399 +but we only want to capture the function + +0:15:35.519,0:15:39.600 +name + +0:15:36.399,0:15:42.800 +which means the identifier + +0:15:39.600,0:15:46.320 +here so we + +0:15:42.800,0:15:48.639 +move the capture to after the identifier + +0:15:46.320,0:15:48.639 +node + +0:15:49.600,0:15:52.959 +if we want to capture the class names as + +0:15:51.759,0:16:09.839 +well + +0:15:52.959,0:16:09.839 +we just add another pattern + +0:16:10.079,0:16:14.399 +let's look at a more practical example + +0:16:20.320,0:16:23.759 +here we can see that single quotes + +0:16:22.959,0:16:25.600 +strings and + +0:16:23.759,0:16:27.279 +double quotes screens are highlighted + +0:16:25.600,0:16:30.399 +the same + +0:16:27.279,0:16:33.440 +but in some places + +0:16:30.399,0:16:35.440 +because of some coding conventions + +0:16:33.440,0:16:37.279 +it may be desirable to highlight them + +0:16:35.440,0:16:39.680 +differently for example if + +0:16:37.279,0:16:40.880 +the string is single quoted we may want + +0:16:39.680,0:16:43.759 +to highlight it + +0:16:40.880,0:16:43.759 +as a constant + +0:16:44.399,0:16:47.600 +let's try to see whether we can + +0:16:46.160,0:16:51.839 +distinguish these + +0:16:47.600,0:16:51.839 +two cases + +0:16:56.240,0:17:00.160 +so here we get all the strings + +0:17:00.639,0:17:04.559 +if we want to see if it's single quotes + +0:17:04.079,0:17:07.520 +or + +0:17:04.559,0:17:07.520 +double quote strings + +0:17:08.799,0:17:12.480 +we can try looking at the first + +0:17:11.039,0:17:15.280 +character + +0:17:12.480,0:17:16.720 +of the string i mean the first character + +0:17:15.280,0:17:19.360 +of the note + +0:17:16.720,0:17:33.600 +to check whether it's a single quote or + +0:17:19.360,0:17:36.080 +a double quote + +0:17:33.600,0:17:36.799 +yeah so for that we use the three + +0:17:36.080,0:17:40.160 +setters + +0:17:36.799,0:17:43.360 +support for predicate in this case + +0:17:40.160,0:17:46.080 +we use a match predicate + +0:17:43.360,0:17:46.799 +to check whether the string where the + +0:17:46.080,0:17:50.320 +note + +0:17:46.799,0:17:51.280 +starts with a single quote and with this + +0:17:50.320,0:17:55.520 +pattern + +0:17:51.280,0:17:55.520 +we only capture the single quotes + +0:17:58.840,0:18:03.760 +strings + +0:18:00.400,0:18:07.760 +let's try to give it a different face + +0:18:03.760,0:18:07.760 +so we copy the pattern + +0:18:13.039,0:18:16.640 +and we add this pattern + +0:18:18.640,0:18:21.760 +pop item only + +0:18:25.120,0:18:31.440 +but we also want to give the + +0:18:28.400,0:18:36.320 +capture a different name + +0:18:31.440,0:18:36.320 +let's say we want to highlight it as a + +0:18:40.840,0:18:43.840 +keyword + +0:18:46.559,0:18:57.840 +and now if we refresh the buffer + +0:19:06.320,0:19:10.320 +we see that single quote strings are + +0:19:08.799,0:19:12.880 +highlighted as + +0:19:10.320,0:19:12.880 +keywords + +0:19:14.400,0:19:19.200 +the highlighting patterns can also be + +0:19:16.400,0:19:23.280 +set for a single project + +0:19:19.200,0:19:23.280 +using directory local variable + +0:19:23.440,0:19:30.000 +for example let's take a look at + +0:19:26.880,0:19:30.000 +ems source code + +0:19:35.760,0:19:43.760 +so in image c source there are a lot of + +0:19:40.400,0:19:47.679 +uses of these different macros + +0:19:43.760,0:19:50.400 +to define functions + +0:19:47.679,0:19:50.400 +and you can see + +0:19:51.200,0:19:55.760 +this is actually the function name but + +0:19:53.520,0:19:59.120 +it's highlighted as the + +0:19:55.760,0:20:03.679 +string so what we want + +0:19:59.120,0:20:07.600 +is to somehow recognize this pattern + +0:20:03.679,0:20:11.280 +and highlight it + +0:20:07.600,0:20:14.559 +as highlight this part + +0:20:11.280,0:20:17.679 +with the function phase instead + +0:20:14.559,0:20:20.240 +in order to do that + +0:20:17.679,0:20:21.760 +we put a pattern in this project + +0:20:20.240,0:20:24.880 +directory local + +0:20:21.760,0:20:24.880 +settings file + +0:20:31.760,0:20:37.760 +so we can put this button in the c + +0:20:34.799,0:20:37.760 +mode section + +0:20:40.159,0:20:50.480 +and now if we enable tree sitter + +0:20:48.000,0:20:52.720 +you can see that this is the highlighted + +0:20:50.480,0:20:52.720 +uh + +0:20:53.200,0:20:56.559 +as a normal function definition so this + +0:20:55.520,0:21:00.400 +is the function + +0:20:56.559,0:21:00.400 +face like we wanted + +0:21:01.200,0:21:06.080 +the pattern for this is actually pretty + +0:21:03.760,0:21:06.080 +simple + +0:21:07.200,0:21:09.919 +it's only + +0:21:10.720,0:21:17.440 +only this part so + +0:21:14.720,0:21:19.679 +if it's a function call where the name + +0:21:17.440,0:21:21.600 +of the function is different + +0:21:19.679,0:21:24.159 +then we highlight the different as a + +0:21:21.600,0:21:24.159 +keyword + +0:21:24.240,0:21:28.159 +and then the first string element we + +0:21:27.360,0:21:31.840 +highlighted + +0:21:28.159,0:21:31.840 +as a function name + +0:21:35.360,0:21:39.280 +since the language objects are actually + +0:21:37.679,0:21:40.799 +native code + +0:21:39.280,0:21:43.440 +they have to be compiled for each + +0:21:40.799,0:21:45.600 +platform that we want to support + +0:21:43.440,0:21:48.159 +this will become a big obstacle for + +0:21:45.600,0:21:50.240 +3-seater adoption + +0:21:48.159,0:21:52.960 +therefore i've created a language window + +0:21:50.240,0:21:54.960 +package 3-seater length + +0:21:52.960,0:21:56.320 +that takes care of pre-compiling the + +0:21:54.960,0:21:59.679 +grammars the

+0:22:04.080,0:22:08.080 +binaries + +0:22:05.360,0:22:11.280 +and provides some highlighting queries + +0:22:08.080,0:22:11.280 +for some of the languages + +0:22:11.440,0:22:15.919 +it should be noted that this package + +0:22:13.760,0:22:19.520 +should be treated as a temporary + +0:22:15.919,0:22:19.520 +distribution mechanism only + +0:22:19.919,0:22:24.720 +to help with bootstrapping three-seaters + +0:22:22.240,0:22:27.760 +adoption + +0:22:24.720,0:22:29.760 +the plan is that eventually these files + +0:22:27.760,0:22:32.480 +should be provided by the language major + +0:22:29.760,0:22:35.120 +modes themselves + +0:22:32.480,0:22:36.320 +but in order to do that we need better + +0:22:35.120,0:22:40.240 +tooling + +0:22:36.320,0:22:42.559 +so we're not there yet + +0:22:40.240,0:22:43.280 +since the call already works reasonably + +0:22:42.559,0:22:44.640 +well + +0:22:43.280,0:22:46.320 +there are several areas that would + +0:22:44.640,0:22:48.960 +benefit from the community's + +0:22:46.320,0:22:48.960 +contribution + +0:22:49.120,0:22:52.640 +so three seaters upstream language + +0:22:51.520,0:22:54.400 +prepositories + +0:22:52.640,0:22:55.679 +already contain highlighting queries on + +0:22:54.400,0:22:58.480 +their own + +0:22:55.679,0:23:00.480 +however they are pretty basic and they + +0:22:58.480,0:23:02.559 +may not fit well with existing emax + +0:23:00.480,0:23:04.320 +conventions + +0:23:02.559,0:23:07.120 +therefore the language bundle has its + +0:23:04.320,0:23:10.559 +own set of highlighting queries + +0:23:07.120,0:23:11.600 +this requires maintenance until language + +0:23:10.559,0:23:13.760 +measurements adopt + +0:23:11.600,0:23:16.240 +three sitter and maintain the queries on + +0:23:13.760,0:23:16.240 +their own + +0:23:16.640,0:23:22.000 +the queries are actually quite easy to + +0:23:18.480,0:23:24.240 +write as you've already seen + +0:23:22.000,0:23:25.360 +you just need to be familiar with the + +0:23:24.240,0:23:30.000 +language + +0:23:25.360,0:23:32.880 +familiar enough to come up with sensible + +0:23:30.000,0:23:32.880 +highlighting patterns + +0:23:35.200,0:23:39.679 +and if you are a maintainer of a + +0:23:37.600,0:23:42.320 +language major mode + +0:23:39.679,0:23:43.360 +you may want to consider integrating + +0:23:42.320,0:23:46.960 +tree sitter into + +0:23:43.360,0:23:50.080 +your mode initially maybe as an + +0:23:46.960,0:23:53.279 +optional feature the integration is + +0:23:50.080,0:23:56.640 +actually pretty straightforward + +0:23:53.279,0:24:00.880 +especially for syntax highlighting + +0:23:56.640,0:24:00.880 +or alternatively + +0:24:01.520,0:24:04.640 +you can also try writing a new major + +0:24:03.760,0:24:08.000 +mode + +0:24:04.640,0:24:11.360 +from scratch that relies on tree sitter + +0:24:08.000,0:24:11.360 +from the very beginning + +0:24:12.559,0:24:19.679 +the code for such a major mode is + +0:24:16.320,0:24:23.200 +quite simple for example + +0:24:19.679,0:24:26.240 +this is the proposed + +0:24:23.200,0:24:30.720 +what mode for web assembly + +0:24:26.240,0:24:30.720 +the code is just + +0:24:31.039,0:24:37.120 +like one page of code not + +0:24:34.559,0:24:37.120 +not a lot + +0:24:39.520,0:24:46.559 +you can also try writing new minor modes + +0:24:42.720,0:24:50.080 +or writing integration packages + +0:24:46.559,0:24:50.880 +for example a lot of package a lot of + +0:24:50.080,0:24:54.559 +packages + +0:24:50.880,0:24:58.840 +may benefit from tree sitter integration + +0:24:54.559,0:25:01.840 +but no one has written the integration + +0:24:58.840,0:25:01.840 +yet + +0:25:02.960,0:25:06.720 +if you are interested in 3-seater you +

me anytime on questions + +0:01:00.160,0:01:05.860 +regarding emacs + +0:01:01.359,0:01:07.200 +for example at ala at 200ok.ch + +0:01:05.860,0:01:09.600 +[Music] + +0:01:07.200,0:01:11.760 +but back to the topic at hand the + +0:01:09.600,0:01:13.680 +proposition is as following + +0:01:11.760,0:01:15.520 +most work on the computer is based on + +0:01:13.680,0:01:16.479 +either text processing or text + +0:01:15.520,0:01:19.920 +consumption + +0:01:16.479,0:01:20.880 +and very often the text which you need + +0:01:19.920,0:01:23.520 +to process + +0:01:20.880,0:01:24.560 +is in a structured format for example in + +0:01:23.520,0:01:26.640 +json + +0:01:24.560,0:01:28.560 +that might even be if your job is not + +0:01:26.640,0:01:30.400 +programming per se + +0:01:28.560,0:01:33.119 +and reading through such a bigger chunk + +0:01:30.400,0:01:36.479 +of json can be non-trivial however + +0:01:33.119,0:01:39.119 +while just reading and understanding it + +0:01:36.479,0:01:40.320 +will be essential to getting your job + +0:01:39.119,0:01:43.680 +done + +0:01:40.320,0:01:47.200 +so let's quickly check out an example + +0:01:43.680,0:01:50.560 +json file this is from the github api + +0:01:47.200,0:01:53.119 +where which is a request sorry the + +0:01:50.560,0:01:55.280 +response to a request for a specific + +0:01:53.119,0:01:58.560 +issue on the github api so let's + +0:01:55.280,0:01:58.560 +quickly check that one out + +0:01:58.799,0:02:03.280 +okay so here it is open and we can + +0:02:01.280,0:02:05.439 +already see that there is lots of stuff + +0:02:03.280,0:02:08.319 +going on here + +0:02:05.439,0:02:10.319 +it's uh 200 lines it's not going to be + +0:02:08.319,0:02:12.160 +very easy just just to find out what are + +0:02:10.319,0:02:13.920 +the top level things in here what are + +0:02:12.160,0:02:14.560 +the top level attributes of course i can + +0:02:13.920,0:02:16.480 +do this + +0:02:14.560,0:02:17.840 +and maybe it would by hand but that + +0:02:16.480,0:02:20.560 +doesn't scale + +0:02:17.840,0:02:22.560 +i can use cool emacs facilities like the + +0:02:20.560,0:02:24.720 +height show mode and try to + +0:02:22.560,0:02:27.200 +fold all the things that are top level + +0:02:24.720,0:02:29.760 +but that also doesn't really scale + +0:02:27.200,0:02:32.000 +there must be a better way and of course + +0:02:29.760,0:02:34.959 +there is there is prior art + +0:02:32.000,0:02:36.080 +there is a tool called jq i'm going to + +0:02:34.959,0:02:39.120 +quote the usp + +0:02:36.080,0:02:42.959 +from their website jq is like + +0:02:39.120,0:02:44.720 +sed said for json data you can use it to + +0:02:42.959,0:02:46.720 +slice and filter and map + +0:02:44.720,0:02:47.840 +and transform structured data with the + +0:02:46.720,0:02:51.519 +same ease that + +0:02:47.840,0:02:53.920 +z awk grep and friends let you play with + +0:02:51.519,0:02:53.920 +text + +0:02:54.000,0:02:57.519 +let me give you a quick demonstration of + +0:02:56.160,0:02:59.680 +it by the way + +0:02:57.519,0:03:01.920 +it's written in portable c it has zero + +0:02:59.680,0:03:04.959 +runtime dependency so it's very easy + +0:03:01.920,0:03:09.040 +to get started with it and use it on + +0:03:04.959,0:03:12.800 +pretty much any unix-based + +0:03:09.040,0:03:16.159 +computer sorry no linux based computer + +0:03:12.800,0:03:19.599 +apologies okay so let's explore a + +0:03:16.159,0:03:21.120 +json file with it it's a command line + +0:03:19.599,0:03:24.640 +tool and it has a very + +0:03:21.120,0:03:26.799 +simple command line syntax so you + +0:03:24.640,0:03:27.840 +call the binary and then you give it a + +0:03:26.799,0:03:31.680 +query + +0:03:27.840,0:03:33.840 +and a file and then we'll return + +0:03:31.680,0:03:35.440 +its answer so for example if i want the + +0:03:33.840,0:03:38.319 +top level keys + +0:03:35.440,0:03:39.840 +i will just say jq keys the file and it + +0:03:38.319,0:03:42.319 +will return the keys + +0:03:39.840,0:03:43.519 +simple as that so let's check this out + +0:03:42.319,0:03:46.879 +in a real + +0:03:43.519,0:03:50.080 +shell here i am in eshel + +0:03:46.879,0:03:53.200 +let's run jq keys on the github + +0:03:50.080,0:03:56.959 +issue comment and we can see + +0:03:53.200,0:04:00.000 +that we have actually received a list + +0:03:56.959,0:04:02.000 +back here with the top level + +0:04:00.000,0:04:04.319 +things okay so this issue it looks very + +0:04:02.000,0:04:06.239 +very interesting so let's uh ask it to + +0:04:04.319,0:04:10.080 +give me more information on this + +0:04:06.239,0:04:11.360 +issue then it's hairy again that's a lot + +0:04:10.080,0:04:14.319 +of stuff + +0:04:11.360,0:04:17.759 +i mean lucky for for us we are in emacs + +0:04:14.319,0:04:21.040 +here so we can use nice shortcuts we can + +0:04:17.759,0:04:22.000 +copy this we go can go in here just + +0:04:21.040,0:04:24.400 +select that + +0:04:22.000,0:04:25.600 +get that out or something like this but + +0:04:24.400,0:04:28.320 +still + +0:04:25.600,0:04:29.600 +this is not really it's not really the + +0:04:28.320,0:04:34.080 +best way + +0:04:29.600,0:04:36.639 +to do that right it gets kind of tedious + +0:04:34.080,0:04:37.680 +at this point the output can be + +0:04:36.639,0:04:39.360 +humongous + +0:04:37.680,0:04:42.479 +the shell is not really the best place + +0:04:39.360,0:04:43.600 +to read through such big output i mean e + +0:04:42.479,0:04:45.440 +shell is + +0:04:43.600,0:04:47.440 +probably one of the better shells for + +0:04:45.440,0:04:48.560 +this because it's just a regular emacs + +0:04:47.440,0:04:51.199 +buffer but still + +0:04:48.560,0:04:52.720 +it's not really the best tool and i need + +0:04:51.199,0:04:55.280 +to repeat the command + +0:04:52.720,0:04:56.000 +all the time until i finally build the + +0:04:55.280,0:04:59.120 +right query + +0:04:56.000,0:05:02.080 +and all the time i use i lose my + +0:04:59.120,0:05:02.800 +focus i lose what i'm currently looking + +0:05:02.080,0:05:06.080 +at + +0:05:02.800,0:05:08.160 +i'm seeing the new result it would be so + +0:05:06.080,0:05:10.080 +much nicer to have live feedback + +0:05:08.160,0:05:11.600 +and when working with emacs we're quite + +0:05:10.080,0:05:12.320 +used to that so there should be an + +0:05:11.600,0:05:15.120 +option + +0:05:12.320,0:05:17.759 +and of course there is it's emacs right + +0:05:15.120,0:05:20.880 +so you can do anything + +0:05:17.759,0:05:22.960 +there is various good tools for + +0:05:20.880,0:05:26.000 +completion in emacs + +0:05:22.960,0:05:29.039 +i used ivy for this + +0:05:26.000,0:05:31.840 +i'm going to code the usp for ivy + +0:05:29.039,0:05:32.639 +iv is a generic completion mechanism for + +0:05:31.840,0:05:34.639 +emacs + +0:05:32.639,0:05:35.919 +while it operates similarly to other + +0:05:34.639,0:05:38.960 +completion schemes + +0:05:35.919,0:05:40.400 +such as icomplete mode iv aims to be + +0:05:38.960,0:05:43.120 +more efficient smaller + +0:05:40.400,0:05:45.199 +simpler and smoother to use yet highly + +0:05:43.120,0:05:47.840 +customizable + +0:05:45.199,0:05:49.440 +and that's true one of the cool things + +0:05:47.840,0:05:52.479 +of iv + +0:05:49.440,0:05:54.320 +compared to other completion mechanisms + +0:05:52.479,0:05:58.160 +in emacs + +0:05:54.320,0:06:01.600 +is that it can be used on dynamic + +0:05:58.160,0:06:03.520 +data so usually completion works on a + +0:06:01.600,0:06:05.360 +static input for example you're in a + +0:06:03.520,0:06:08.800 +buffer a text buffer + +0:06:05.360,0:06:09.600 +and you use i search maybe with idle + +0:06:08.800,0:06:12.400 +mode + +0:06:09.600,0:06:13.360 +and you find your results that's all + +0:06:12.400,0:06:16.960 +nice + +0:06:13.360,0:06:19.840 +however if i + +0:06:16.960,0:06:20.720 +want to search on dynamic data that + +0:06:19.840,0:06:23.759 +doesn't work + +0:06:20.720,0:06:27.039 +so whenever i type in my query + +0:06:23.759,0:06:28.000 +for jq i actually need to call the jq + +0:06:27.039,0:06:30.160 +binary + +0:06:28.000,0:06:32.840 +and it will give a different result set + +0:06:30.160,0:06:36.319 +back so it's a really + +0:06:32.840,0:06:38.240 +dynamic mechanism that we need here it's + +0:06:36.319,0:06:41.440 +much more like a search engine + +0:06:38.240,0:06:42.560 +and ivy luckily has something built in + +0:06:41.440,0:06:46.000 +and it's called + +0:06:42.560,0:06:48.160 +console so i used council and jq + +0:06:46.000,0:06:49.199 +and combined them and build a new + +0:06:48.160,0:06:52.960 +package + +0:06:49.199,0:06:56.000 +with which we can use emacs and jq + +0:06:52.960,0:06:58.800 +to have live feedback + +0:06:56.000,0:06:59.840 +it's very easy to use so you just call + +0:06:58.800,0:07:02.800 +console.jq + +0:06:59.840,0:07:04.319 +on a buffer containing json for example + +0:07:02.800,0:07:07.280 +the one we have here + +0:07:04.319,0:07:08.319 +let's call console.jq on it and we + +0:07:07.280,0:07:11.280 +already + +0:07:08.319,0:07:13.039 +get a default query the dot query which + +0:07:11.280,0:07:16.080 +just gives us + +0:07:13.039,0:07:17.280 +the same file but now we can change it + +0:07:16.080,0:07:19.039 +and for example + +0:07:17.280,0:07:21.039 +find all the keys in here and then we + +0:07:19.039,0:07:22.800 +see i had this issue this was the one + +0:07:21.039,0:07:24.639 +that we were interested in + +0:07:22.800,0:07:26.479 +so let's find more information on the + +0:07:24.639,0:07:28.800 +issue what + +0:07:26.479,0:07:31.680 +keys does it have actually have uh it + +0:07:28.800,0:07:34.800 +has assignees that that interests me + +0:07:31.680,0:07:37.039 +so let's check out the assignees in here + +0:07:34.800,0:07:39.759 +there's two of them but i'm only + +0:07:37.039,0:07:42.000 +interested in the first one + +0:07:39.759,0:07:43.599 +i'm making stuff up as i go here of + +0:07:42.000,0:07:46.000 +course + +0:07:43.599,0:07:47.039 +and whenever i hit enter i get a new + +0:07:46.000,0:07:50.160 +buffer + +0:07:47.039,0:07:53.520 +which just shows me this + +0:07:50.160,0:07:55.599 +particular result for the particular + +0:07:53.520,0:07:59.199 +query that i entered + +0:07:55.599,0:08:03.199 +so let me do that again we are in here + +0:07:59.199,0:08:05.840 +we are looking at a + +0:08:03.199,0:08:07.520 +json file this can be very very big + +0:08:05.840,0:08:09.520 +doesn't also need to be a file just + +0:08:07.520,0:08:12.160 +needs to be a buffer + +0:08:09.520,0:08:13.599 +you call console.jq on it and you can do + +0:08:12.160,0:08:16.479 +any kind of + +0:08:13.599,0:08:18.080 +query on it for example let's see if + +0:08:16.479,0:08:20.319 +there is a url here + +0:08:18.080,0:08:23.759 +yes there's a url let's see if there's a + +0:08:20.319,0:08:26.879 +repository here repository + +0:08:23.759,0:08:33.360 +no there isn't what was it called issue + +0:08:26.879,0:08:33.360 +keys repository url it was called okay + +0:08:33.440,0:08:40.240 +so let's see issue pause + +0:08:36.640,0:08:42.959 +url and then we see so + +0:08:40.240,0:08:44.159 +apparently this issue command is for a + +0:08:42.959,0:08:47.839 +repository called + +0:08:44.159,0:08:50.320 +organize i wonder what that might be + +0:08:47.839,0:08:52.640 +okay so that was a very short + +0:08:50.320,0:08:54.800 +introduction to console jq + +0:08:52.640,0:08:56.800 +you can see the timer here i only have + +0:08:54.800,0:08:57.440 +one minute left to go so i'm going to + +0:08:56.800,0:08:59.760 +leave + +0:08:57.440,0:09:01.519 +with a very very short introduction to + +0:08:59.760,0:09:05.040 +the console gq + +0:09:01.519,0:09:07.519 +code it's not even 60 lines + +0:09:05.040,0:09:09.600 +of e-lisp so building something like + +0:09:07.519,0:09:12.800 +this is very very easy + +0:09:09.600,0:09:14.560 +i would encourage you to go and read + +0:09:12.800,0:09:16.160 +through the code in your own time + +0:09:14.560,0:09:18.320 +if you're interested in building + +0:09:16.160,0:09:19.600 +something like this if you're interested + +0:09:18.320,0:09:22.720 +in just using + +0:09:19.600,0:09:24.320 +jq or you're done + +0:09:22.720,0:09:25.839 +these are the links to all the tools + +0:09:24.320,0:09:28.800 +console.jq of course + +0:09:25.839,0:09:29.519 +is readily available on melpah also + +0:09:28.800,0:09:32.959 +developed + +0:09:29.519,0:09:36.080

also a great + +0:09:39.839,0:09:43.120 +free software tool maybe that interests + +0:09:42.399,0:09:46.240 +you + +0:09:43.120,0:09:48.800 +thank you for listening have great time +

+0:00:09.840,0:00:13.360 +and how it has changed my life + +0:00:14.400,0:00:19.520 +right so who am i i am a senior at + +0:00:17.359,0:00:22.800 +stanford online high school + +0:00:19.520,0:00:24.320 +and i am also a violinist + +0:00:22.800,0:00:26.960 +i started violin when i was two and a + +0:00:24.320,0:00:29.119 +half and i have been + +0:00:26.960,0:00:30.240 +keeping it up ever since violin is a + +0:00:29.119,0:00:33.360 +huge part of my life + +0:00:30.240,0:00:36.239 +and i am very much a musician at heart + +0:00:33.360,0:00:37.840 +i am also a somewhat capable programmer + +0:00:36.239,0:00:39.280 +i've done a lot of informal programming + +0:00:37.840,0:00:42.559 +in the past + +0:00:39.280,0:00:44.079 +and this year i'm taking my first ap + +0:00:42.559,0:00:47.440 +compsci course + +0:00:44.079,0:00:51.039 +in my high school and so + +0:00:47.440,0:00:54.239 +i've done a lot of side projects + +0:00:51.039,0:00:56.800 +mainly in python and some very short + +0:00:54.239,0:00:59.840 +scripts in e-lisp + +0:00:56.800,0:01:02.879 +and last but not least i am a tinker + +0:00:59.840,0:01:06.720 +i love to play around with things and + +0:01:02.879,0:01:10.240 +see what i can do better and just + +0:01:06.720,0:01:10.240 +have as much fun as possible + +0:01:10.880,0:01:14.479 +so how did i find emacs + +0:01:15.040,0:01:18.880 +i discovered it actually through a talk + +0:01:17.600,0:01:21.360 +funnily enough + +0:01:18.880,0:01:23.520 +at a vim conference given by aaron + +0:01:21.360,0:01:25.840 +bieber + +0:01:23.520,0:01:28.320 +titled evil mode or how i learned to + +0:01:25.840,0:01:31.439 +stop worrying and love emacs + +0:01:28.320,0:01:33.360 +i watched that talk a couple times over + +0:01:31.439,0:01:35.759 +just marveling at all the wonderful + +0:01:33.360,0:01:38.799 +things that he could do in emacs + +0:01:35.759,0:01:41.680 +and being a previous vim user myself + +0:01:38.799,0:01:42.399 +i found it very enticing to be able to + +0:01:41.680,0:01:44.960 +have + +0:01:42.399,0:01:47.040 +the evil mode package and very quickly + +0:01:44.960,0:01:48.799 +switch to emacs + +0:01:47.040,0:01:51.040 +at the time i was also in my sophomore + +0:01:48.799,0:01:54.640 +year and so + +0:01:51.040,0:01:56.320 +i had had sort of a note-taking system + +0:01:54.640,0:01:59.360 +in the past + +0:01:56.320,0:02:01.680 +but it was not good um and i needed a + +0:01:59.360,0:02:03.759 +more organized note-taking system + +0:02:01.680,0:02:04.960 +my parents had suggested paper for a + +0:02:03.759,0:02:08.160 +while and + +0:02:04.960,0:02:10.959 +there was the whole organization + +0:02:08.160,0:02:12.080 +part of that but that did not really + +0:02:10.959,0:02:14.000 +work out for me + +0:02:12.080,0:02:16.239 +and so i was trying to find this better + +0:02:14.000,0:02:19.440 +note-taking system + +0:02:16.239,0:02:22.239 +and it was very hard + +0:02:19.440,0:02:23.520 +i had two main criteria which i did not + +0:02:22.239,0:02:25.360 +define at the time + +0:02:23.520,0:02:26.640 +but i realized was really what i was + +0:02:25.360,0:02:28.720 +looking for + +0:02:26.640,0:02:30.959 +first of all it had to be flexible + +0:02:28.720,0:02:33.920 +enough and second of all it had + +0:02:30.959,0:02:34.959 +i had to have control over the data and + +0:02:33.920,0:02:37.519 +so + +0:02:34.959,0:02:39.680 +through this process i actually went + +0:02:37.519,0:02:42.640 +through a bunch of note-taking softwares + +0:02:39.680,0:02:44.080 +rather systematically i went through + +0:02:42.640,0:02:47.519 +google docs + +0:02:44.080,0:02:49.840 +which very much did not work out + +0:02:47.519,0:02:50.640 +i also went through evernote which also + +0:02:49.840,0:02:53.200 +was not + +0:02:50.640,0:02:55.200 +great for me and one note which i + +0:02:53.200,0:02:58.800 +settled on for a little while + +0:02:55.200,0:03:01.519 +but it did not meet these criteria + +0:02:58.800,0:03:02.159 +particularly the second one i had taken + +0:03:01.519,0:03:05.280 +some notes + +0:03:02.159,0:03:07.519 +and i wanted to export it and onenote + +0:03:05.280,0:03:12.000 +did not let me do that + +0:03:07.519,0:03:14.879 +it was pdf horribly organized pdf + +0:03:12.000,0:03:17.200 +and that's when i knew i needed some + +0:03:14.879,0:03:17.200 +change + +0:03:17.440,0:03:24.080 +so i discovered emacs through this talk + +0:03:21.519,0:03:26.640 +and through the wonderful features of + +0:03:24.080,0:03:26.640 +org mode + +0:03:27.040,0:03:34.000 +this is my first journal entry in emacs + +0:03:30.080,0:03:36.159 +i had been playing with it for one day + +0:03:34.000,0:03:38.159 +and i was on the org agenda and i + +0:03:36.159,0:03:40.720 +happened to press i + +0:03:38.159,0:03:41.599 +which for the emacs combined is the + +0:03:40.720,0:03:45.440 +default for + +0:03:41.599,0:03:48.720 +diary entry and so i was very excited + +0:03:45.440,0:03:50.239 +um and i shouldn't stay on the slide too + +0:03:48.720,0:03:53.760 +long unless you read it + +0:03:50.239,0:03:57.200 +um so let's move on to the next one + +0:03:53.760,0:04:00.480 +um so the learning curve for me i think + +0:03:57.200,0:04:03.760 +particularly being an xbm user + +0:04:00.480,0:04:06.080 +evil mode made it very easy to switch + +0:04:03.760,0:04:07.439 +thankfully i there was the emax + +0:04:06.080,0:04:10.799 +reference sheet + +0:04:07.439,0:04:14.080 +and having evil mode to + +0:04:10.799,0:04:17.440 +switch between um + +0:04:14.080,0:04:17.919 +texts and whether it be editing a text + +0:04:17.440,0:04:20.560 +file + +0:04:17.919,0:04:21.600 +or going to other parts of just emacs in + +0:04:20.560,0:04:24.800 +general + +0:04:21.600,0:04:26.840 +i think vim really helped with making me + +0:04:24.800,0:04:28.000 +feel comfortable within this new + +0:04:26.840,0:04:31.440 +environment + +0:04:28.000,0:04:31.919 +and so having that experience i also + +0:04:31.440,0:04:34.240 +wasn't + +0:04:31.919,0:04:36.320 +new to the keybind-based world i have + +0:04:34.240,0:04:40.160 +been very comfortable with computer + +0:04:36.320,0:04:43.520 +and the keyboard for most of my life + +0:04:40.160,0:04:45.520 +and so it was not a totally new + +0:04:43.520,0:04:47.440 +environment for me + +0:04:45.520,0:04:49.360 +i also spent a lot of time looking at + +0:04:47.440,0:04:53.040 +the emacs reference sheet + +0:04:49.360,0:04:55.040 +just thinking about trying to find + +0:04:53.040,0:04:56.639 +all of the different functions if i + +0:04:55.040,0:04:59.680 +didn't know what something was + +0:04:56.639,0:05:01.199 +then i queried it in emacs and then i + +0:04:59.680,0:05:03.759 +figured out what it was + +0:05:01.199,0:05:05.600 +and that was one of the best ways for me + +0:05:03.759,0:05:09.280 +to discover + +0:05:05.600,0:05:09.280 +all of the capabilities of emacs + +0:05:09.360,0:05:12.800 +thirdly of course the self-documenting + +0:05:11.440,0:05:15.199 +feature + +0:05:12.800,0:05:17.120 +or nature of emacs and narrowing + +0:05:15.199,0:05:20.479 +frameworks such as helm + +0:05:17.120,0:05:21.360 +really helped find things especially for + +0:05:20.479,0:05:25.919 +mx + +0:05:21.360,0:05:28.160 +for a while i was just + +0:05:25.919,0:05:29.520 +i would go about my day and if i pressed + +0:05:28.160,0:05:30.720 +to keep mine that i didn't know what it + +0:05:29.520,0:05:34.560 +did + +0:05:30.720,0:05:36.240 +i would do the losses and + +0:05:34.560,0:05:37.600 +see the list of key binds that i had + +0:05:36.240,0:05:40.400 +pressed and + +0:05:37.600,0:05:41.280 +tried to find that one and query the + +0:05:40.400,0:05:45.199 +function + +0:05:41.280,0:05:45.199 +and what not so + +0:05:45.280,0:05:51.759 +yeah and now we jump to now so + +0:05:49.120,0:05:53.280 +there there is at least one moment in + +0:05:51.759,0:05:55.600 +each day when i think + +0:05:53.280,0:05:57.680 +how would i live without umax + +0:05:55.600,0:05:59.120 +particularly now during my senior year + +0:05:57.680,0:06:02.720 +in high school + +0:05:59.120,0:06:05.520 +things are very busy with school violin + +0:06:02.720,0:06:06.400 +and other side projects it's pretty + +0:06:05.520,0:06:09.680 +crazy + +0:06:06.400,0:06:12.720 +and so emacs + +0:06:09.680,0:06:14.479 +and org mode has really helped me stay + +0:06:12.720,0:06:16.960 +on track with everything + +0:06:14.479,0:06:18.840 +and the flexibility of these software is + +0:06:16.960,0:06:21.600 +being able to have things in different + +0:06:18.840,0:06:24.639 +files notes within the tasks + +0:06:21.600,0:06:25.840 +all of that stuff has been truly a + +0:06:24.639,0:06:28.400 +lifesaver + +0:06:25.840,0:06:31.199 +and so i think i can confidently say + +0:06:28.400,0:06:34.560 +that i have found emacs to be + +0:06:31.199,0:06:34.560 +the perfect software for me + +0:06:35.280,0:06:42.240 +over the past two years of using emacs + +0:06:38.639,0:06:45.039 +now it is about two years and two months + +0:06:42.240,0:06:46.160 +i have built a fairly well organized + +0:06:45.039,0:06:49.520 +2000 + +0:06:46.160,0:06:52.160 +plus line org literate config + +0:06:49.520,0:06:53.840 +and so i actually i started with an + +0:06:52.160,0:06:56.800 +e-lisp config + +0:06:53.840,0:06:57.919 +just the vanilla e-max with evil mode + +0:06:56.800,0:07:00.319 +and i built it up + +0:06:57.919,0:07:02.400 +from there eventually i switched to org + +0:07:00.319,0:07:05.840 +literate configs + +0:07:02.400,0:07:10.080 +and used that to organize the snippets + +0:07:05.840,0:07:14.000 +that i was putting in there and so + +0:07:10.080,0:07:16.639 +yeah this is really my workflow now + +0:07:14.000,0:07:18.960 +currently about 90 of everything i do on + +0:07:16.639,0:07:21.520 +my computer is in emacs + +0:07:18.960,0:07:22.319 +the most notable things of course the + +0:07:21.520,0:07:26.000 +list is far + +0:07:22.319,0:07:28.160 +too long to put on one slide but i do a + +0:07:26.000,0:07:31.280 +lot of my programming in emacs + +0:07:28.160,0:07:33.759 +mainly python and e-lisp + +0:07:31.280,0:07:35.199 +because of my ap comp sci class i have + +0:07:33.759,0:07:38.720 +to do java as well + +0:07:35.199,0:07:41.759 +and thank goodness emacs has wonderful + +0:07:38.720,0:07:41.759 +support for that as well + +0:07:41.840,0:07:48.800 +also i do all of my school assignments + +0:07:45.840,0:07:50.400 +more or less in emacs essay writing i do + +0:07:48.800,0:07:51.919 +an org mode and i have some template + +0:07:50.400,0:07:53.919 +files + +0:07:51.919,0:07:55.039 +template org files which i just include + +0:07:53.919,0:07:58.160 +at the top + +0:07:55.039,0:08:01.440 +and then i can export easily to latex + +0:07:58.160,0:08:04.400 +and a beautiful pdf + +0:08:01.440,0:08:05.840 +math physics same thing latex fragments + +0:08:04.400,0:08:09.599 +are a lifesaver + +0:08:05.840,0:08:13.199 +and also really pretty + +0:08:09.599,0:08:15.520 +and i take notes on basically everything + +0:08:13.199,0:08:16.319 +at first i had things separate and then + +0:08:15.520,0:08:19.360 +i started + +0:08:16.319,0:08:21.360 +sort of putting it all into onenotes.org + +0:08:19.360,0:08:24.000 +file or most of it into one + +0:08:21.360,0:08:24.960 +file and that has actually worked out + +0:08:24.000,0:08:26.479 +surprisingly well + +0:08:24.960,0:08:28.879 +especially with all the searching + +0:08:26.479,0:08:33.440 +features of agenda + +0:08:28.879,0:08:35.680 +and whatnot um and i also use mail + +0:08:33.440,0:08:37.680 +i recently made the switch probably + +0:08:35.680,0:08:40.479 +about one or two months ago + +0:08:37.680,0:08:40.959 +and it has been one of the best switches + +0:08:40.479,0:08:44.480 +i've + +0:08:40.959,0:08:46.320 +i've ever had especially given + +0:08:44.480,0:08:47.839 +connecting to tasks all of this + +0:08:46.320,0:08:50.640 +wonderful stuff + +0:08:47.839,0:08:54.160 +just putting even more in emacs is + +0:08:50.640,0:08:57.680 +always a good thing i found + +0:08:54.160,0:08:59.760 +so reflecting back on my journey i think + +0:08:57.680,0:09:01.440 +one of the most important things was + +0:08:59.760,0:09:04.480 +just having a reason to use it + +0:09:01.440,0:09:06.080 +when i came to emacs i had something + +0:09:04.480,0:09:09.600 +that i was looking for + +0:09:06.080,0:09:09.839 +and as soon as i found it i delved right + +0:09:09.600,0:09:12.720 +in + +0:09:09.839,0:09:14.480 +and i i started using it for that thing + +0:09:12.720,0:09:16.959 +and so i was sort of forced to + +0:09:14.480,0:09:19.279 +take the time to read the docs and + +0:09:16.959,0:09:22.399 +figure out what functions i needed + +0:09:19.279,0:09:25.839 +to function and how + +0:09:22.399,0:09:29.519 +i was going to put my workflow + +0:09:25.839,0:09:29.519 +and also of course the desire to tinker + +0:09:30.399,0:09:36.800 +and yeah so really what's next for me + +0:09:33.519,0:09:38.640 +is just wanting to become a more active + +0:09:36.800,0:09:40.640 +member of the emacs community + +0:09:38.640,0:09:43.760 +i want to give back and i think this + +0:09:40.640,0:09:45.920 +talk is sort of the first step to that + +0:09:43.760,0:09:48.000 +being a more active part of this + +0:09:45.920,0:09:51.040 +community that has + +0:09:48.000,0:09:54.000 +indirectly perhaps um but just like + +0:09:51.040,0:09:55.839 +really helped me become a better and + +0:09:54.000,0:09:58.880 +more organized human being + +0:09:55.839,0:10:01.920 +um i have some package ideas that i'm + +0:09:58.880,0:10:05.839 +slowly working on and yeah i just hope + +0:10:01.920,0:10:05.839 +to spread the word + +0:10:05.920,0:10:09.360 +so thank you very much for listening to + +0:10:08.000,0:10:11.360 +my lightning talk +

talking about emacs i'm + +0:00:54.160,0:00:58.960 +happy for you but + +0:00:55.360,0:01:00.960 +it's too much um so i think i + +0:00:58.960,0:01:04.960 +overwhelmed them a little bit at first + +0:01:00.960,0:01:08.000 +um but i think ever since i've sort of + +0:01:04.960,0:01:09.920 +formulated my configuration and i um + +0:01:08.000,0:01:11.600 +just been working with that workflow i +

+0:01:35.920,0:01:42.320 +um so usually around like 100 110 + +0:01:38.960,0:01:43.840 +words per minute and so that just in + +0:01:42.320,0:01:46.079 +general helps + +0:01:43.840,0:01:47.600 +also yeah snippet i think that's how you + +0:01:46.079,0:01:50.960 +pronounce it + +0:01:47.600,0:01:53.920 +i use a lot of snippets for + +0:01:50.960,0:01:54.640 +latex fragments integrals uh you know +

think um + +0:02:04.320,0:02:07.119 +but i could + +0:02:05.360,0:02:09.200 +i could probably make that public at + +0:02:07.119,0:02:11.120 +some point um + +0:02:09.200,0:02:12.959 +and yeah latex fibers have been a + +0:02:11.120,0:02:15.680 +lifesaver in everything + +0:02:12.959,0:02:16.959 +um i've even gotten like pretty used to + +0:02:15.680,0:02:19.040 +typing matrices +

think i think it does help yeah for + +0:02:35.120,0:02:39.840 +sure i think + +0:02:37.120,0:02:41.040 +having a structured system um with + +0:02:39.840,0:02:44.239 +school + +0:02:41.040,0:02:45.920 +or school makes it easier to have a very + +0:02:44.239,0:02:48.720 +structured system + +0:02:45.920,0:02:49.519 +i made a script to sort of fetch + +0:02:48.720,0:02:51.519 +assignments + +0:02:49.519,0:02:53.440 +and that has been given me like a good + +0:02:51.519,0:02:55.440 +playground + +0:02:53.440,0:02:57.040 +to test out these things in a very + +0:02:55.440,0:03:00.720 +structured sort of + +0:02:57.040,0:03:02.720 +environment um so fetching assignments + +0:03:00.720,0:03:05.440 +where to put them into augmented files + +0:03:02.720,0:03:09.040 +the data that i can include in those + +0:03:05.440,0:03:12.640 +um and then doing everything else + +0:03:09.040,0:03:14.720 +um yeah i think that has been + +0:03:12.640,0:03:17.599 +really really helpful um and just + +0:03:14.720,0:03:20.080 +jumping jumping questions + +0:03:17.599,0:03:20.879 +uh i'm just uh interjecting for a second + +0:03:20.080,0:03:22.080 +if you could just take + +0:03:20.879,0:03:24.400 +one or two more questions that would be + +0:03:22.080,0:03:26.799 +perfect sounds good + +0:03:24.400,0:03:27.920 +um i used vim in the first place mainly + +0:03:26.799,0:03:31.120 +for programming + +0:03:27.920,0:03:32.720 +um that was i didn't use it for markdown + +0:03:31.120,0:03:35.840 +or anything + +0:03:32.720,0:03:37.200 +but i got used to some of the keybinds + +0:03:35.840,0:03:39.599 +and actually funnily enough when i + +0:03:37.200,0:03:42.239 +started using emacs i started using more + +0:03:39.599,0:03:43.440 +vim keybinds got used to the hjkl and + +0:03:42.239,0:03:47.680 +all that stuff + +0:03:43.440,0:03:51.440 +and finally um i would probably + +0:03:47.680,0:03:53.840 +use doom or space max i started an emac + +0:03:51.440,0:03:56.560 +circle but i haven't done much yet + +0:03:53.840,0:03:57.920 +so probably something like that and + +0:03:56.560,0:04:00.239 +really the important thing is having a + +0:03:57.920,0:04:02.239 +reason to use emacs + +0:04:00.239,0:04:03.920 +and so i would try to find that for for + +0:04:02.239,0:04:06.319 +every person +

+0:00:02.879,0:00:06.960 +state of retrogaming and emacs + +0:00:04.520,0:00:08.639 +[Music] + +0:00:06.960,0:00:12.000 +first of all a little bit about myself + +0:00:08.639,0:00:13.599 +my name is neilman i'm 28 years old + +0:00:12.000,0:00:15.200 +i work as a cyber security consultant + +0:00:13.599,0:00:17.440 +msg systems and + +0:00:15.200,0:00:19.359 +test other people's web applications and + +0:00:17.440,0:00:20.160 +review the source code for security + +0:00:19.359,0:00:22.960 +problems + +0:00:20.160,0:00:25.039 +you can reach me by email i have my own + +0:00:22.960,0:00:26.480 +self-hosted git repositories + +0:00:25.039,0:00:28.480 +and i have a blog where you can + +0:00:26.480,0:00:32.160 +occasionally find new posts by me on all + +0:00:28.480,0:00:34.800 +kinds of things not just emix things + +0:00:32.160,0:00:36.480 +so but the motivation about this one i + +0:00:34.800,0:00:38.079 +found that emacs is the ultimate + +0:00:36.480,0:00:40.160 +procrastination machine and there are + +0:00:38.079,0:00:41.200 +lots of fun demonstrations i'll go over + +0:00:40.160,0:00:44.160 +a few of them + +0:00:41.200,0:00:46.079 +for example someone made a thing to + +0:00:44.160,0:00:48.239 +order sell it for himself online so it + +0:00:46.079,0:00:50.879 +doesn't have to walk over to the shop + +0:00:48.239,0:00:51.760 +there's plenty rc bots there's some game + +0:00:50.879,0:00:53.520 +things + +0:00:51.760,0:00:55.600 +there's an emulator for the z machine + +0:00:53.520,0:00:57.600 +which you can use to play zorg + +0:00:55.600,0:00:59.039 +and so i asked myself at this point can + +0:00:57.600,0:01:01.039 +you actually emulate retro games at + +0:00:59.039,0:01:02.800 +60fps and it looked around a bit + +0:01:01.039,0:01:04.479 +and found some projects but none that + +0:01:02.800,0:01:07.360 +were actually able to + +0:01:04.479,0:01:08.000 +do it at 60fps so i set out to do my own + +0:01:07.360,0:01:09.439 +one + +0:01:08.000,0:01:11.119 +and looked out for a console that you + +0:01:09.439,0:01:13.439 +can actually emulate at that speed + +0:01:11.119,0:01:14.690 +using emax with its very very limited + +0:01:13.439,0:01:16.320 +rendering + +0:01:14.690,0:01:19.520 +[Music] + +0:01:16.320,0:01:20.560 +and here's the project chip8.el it's + +0:01:19.520,0:01:22.880 +pretty much finished + +0:01:20.560,0:01:24.000 +it clocks into under 1000 sourced lines + +0:01:22.880,0:01:26.159 +of code + +0:01:24.000,0:01:28.080 +it supports the superchip 8 extensions + +0:01:26.159,0:01:30.159 +it runs at full speed all games behave + +0:01:28.080,0:01:32.320 +okay as far as i'm concerned and + +0:01:30.159,0:01:34.479 +yeah i'm pretty happy with it it's very + +0:01:32.320,0:01:37.040 +much the hell world of emulation + +0:01:34.479,0:01:40.880 +and i might maybe do some other + +0:01:37.040,0:01:43.360 +emulation projects in the future + +0:01:40.880,0:01:45.439 +now for the section which is the longest + +0:01:43.360,0:01:46.320 +bunch of fun facts about ship a dot el + +0:01:45.439,0:01:49.759 +which i've learned + +0:01:46.320,0:01:52.240 +during this project so + +0:01:49.759,0:01:54.640 +what the hell is debate anyway first of + +0:01:52.240,0:01:56.799 +all unlike many other emulation game + +0:01:54.640,0:01:58.560 +things it's not a console but a vm + +0:01:56.799,0:02:00.000 +it was designed for easy parting of home + +0:01:58.560,0:02:02.560 +computer games + +0:02:00.000,0:02:03.680 +it wasn't terribly successful and but + +0:02:02.560,0:02:04.320 +there's still a small community of + +0:02:03.680,0:02:06.079 +enthusiasts + +0:02:04.320,0:02:09.119 +writing games for it and there are even + +0:02:06.079,0:02:11.920 +a few demos + +0:02:09.119,0:02:14.720 +this vm has system specs it has a very + +0:02:11.920,0:02:14.959 +very simple 8-bit cpu with 16 registers + +0:02:14.720,0:02:17.760 +and + +0:02:14.959,0:02:18.160 +36 fixed size instructions you have a + +0:02:17.760,0:02:20.560 +whole + +0:02:18.160,0:02:22.080 +4 kilobyte of ram you have a stack with + +0:02:20.560,0:02:24.480 +16 return addresses + +0:02:22.080,0:02:25.760 +the resolution is 64 by 32 black white + +0:02:24.480,0:02:28.000 +pixels + +0:02:25.760,0:02:29.440 +rendering is done by drawing sprites + +0:02:28.000,0:02:30.160 +these are drawn in excel mode meaning + +0:02:29.440,0:02:32.239 +that if you + +0:02:30.160,0:02:33.840 +draw a sprite and set a bit it just + +0:02:32.239,0:02:35.040 +flips over from black to white or white + +0:02:33.840,0:02:36.560 +to black + +0:02:35.040,0:02:38.239 +first one you have a modern buzz that + +0:02:36.560,0:02:40.640 +can just beep at one + +0:02:38.239,0:02:43.120 +frequency and most unusually there's a + +0:02:40.640,0:02:45.360 +hexadecimal keypad as input + +0:02:43.120,0:02:48.160 +so the keys are basically zero to nine + +0:02:45.360,0:02:48.160 +and a to f + +0:02:48.480,0:02:52.400 +so how does this whole thing work it + +0:02:50.879,0:02:53.599 +runs an unspecified speed + +0:02:52.400,0:02:54.879 +you'll probably have to do some fine + +0:02:53.599,0:02:56.080 +tune you find the speed you're happy + +0:02:54.879,0:02:58.560 +with + +0:02:56.080,0:03:01.120 +sound and delay timers exist they count + +0:02:58.560,0:03:02.879 +down at 60fps down to zero + +0:03:01.120,0:03:05.120 +this is done so that you can play a + +0:03:02.879,0:03:06.640 +sound at some specific time + +0:03:05.120,0:03:08.640 +the game itself is loaded with a fixed + +0:03:06.640,0:03:10.480 +offset into ram the program account is + +0:03:08.640,0:03:11.920 +set to exactly that offset + +0:03:10.480,0:03:13.840 +and from there it enters the game loop + +0:03:11.920,0:03:15.519 +where decodes and instruction executes + +0:03:13.840,0:03:18.130 +it for the side effects and just + +0:03:15.519,0:03:19.599 +loops and does this at infinitum + +0:03:18.130,0:03:21.920 +[Music] + +0:03:19.599,0:03:23.920 +so the game was the first thing where + +0:03:21.920,0:03:24.239 +into problems the usual game approach is + +0:03:23.920,0:03:26.640 +to + +0:03:24.239,0:03:28.239 +do stuff figure out how long to eight + +0:03:26.640,0:03:30.640 +wait for exactly that much and + +0:03:28.239,0:03:31.680 +repeat this doesn't work well in imax at + +0:03:30.640,0:03:34.959 +all because well + +0:03:31.680,0:03:37.280 +user input basically and + +0:03:34.959,0:03:39.040 +emacs is designed to just do whatever it + +0:03:37.280,0:03:40.080 +needs to do whenever you enter use input + +0:03:39.040,0:03:42.799 +instead of + +0:03:40.080,0:03:43.440 +doing things at one specific time if you + +0:03:42.799,0:03:45.040 +try to do + +0:03:43.440,0:03:46.640 +interruptable sleep well you get + +0:03:45.040,0:03:49.440 +unpredictable behavior + +0:03:46.640,0:03:50.959 +for example can be the timer doesn't run + +0:03:49.440,0:03:52.560 +at all at next time because you've + +0:03:50.959,0:03:54.400 +accidentally cancelled it + +0:03:52.560,0:03:55.760 +if you do uninterruptable sleep it's + +0:03:54.400,0:03:56.720 +freezes instead which isn't what you + +0:03:55.760,0:03:59.360 +want either + +0:03:56.720,0:04:00.560 +so i went for timers which forced me to + +0:03:59.360,0:04:02.159 +do inversion of control + +0:04:00.560,0:04:04.080 +meaning that i have to write code in the + +0:04:02.159,0:04:06.159 +style where it's just call it + +0:04:04.080,0:04:07.200 +time and this allows this input to + +0:04:06.159,0:04:09.120 +happen and to + +0:04:07.200,0:04:11.040 +for things to progress at roughly the + +0:04:09.120,0:04:12.879 +speed i want to + +0:04:11.040,0:04:14.159 +so there's the skydiver function which + +0:04:12.879,0:04:16.000 +is called a 60fps + +0:04:14.159,0:04:17.359 +and i have to be very careful to not do + +0:04:16.000,0:04:20.479 +too much in it + +0:04:17.359,0:04:22.960 +and say this function execute cpu cycles + +0:04:20.479,0:04:23.680 +decrypt the sound delay registers and + +0:04:22.960,0:04:27.759 +redraw + +0:04:23.680,0:04:28.800 +the screen so to map this whole system + +0:04:27.759,0:04:31.199 +to mx lisp + +0:04:28.800,0:04:33.120 +i've used just integers and vectors + +0:04:31.199,0:04:35.040 +which contain even more integers + +0:04:33.120,0:04:37.759 +this is used for the ram registers + +0:04:35.040,0:04:39.120 +return stack key state screen and so on + +0:04:37.759,0:04:41.520 +and so forth basically + +0:04:39.120,0:04:42.800 +what you would do if you were writing c + +0:04:41.520,0:04:44.560 +all of this is stored in global + +0:04:42.800,0:04:46.479 +variables i'm not using any + +0:04:44.560,0:04:48.400 +lists at all and as a side effect + +0:04:46.479,0:04:50.320 +there's no constant going on at all + +0:04:48.400,0:04:51.120 +there are no extra objects created which + +0:04:50.320,0:04:53.919 +would trigger + +0:04:51.120,0:04:55.840 +garbage collection pulses this getting + +0:04:53.919,0:04:56.720 +this red was rather tricky actually and + +0:04:55.840,0:04:58.560 +there were some + +0:04:56.720,0:05:01.680 +in garbage collection problems which i + +0:04:58.560,0:05:01.680 +had to resolve over time + +0:05:01.759,0:05:05.520 +so the coding instructions for this you + +0:05:04.320,0:05:06.800 +have to know that all instructions are + +0:05:05.520,0:05:08.880 +two bytes long + +0:05:06.800,0:05:10.240 +and the arguments encoded inside them + +0:05:08.880,0:05:11.440 +for example the jump to address + +0:05:10.240,0:05:15.120 +instruction + +0:05:11.440,0:05:18.400 +is encoded as one and three hex digits + +0:05:15.120,0:05:20.800 +the type is extracted masking with f000 + +0:05:18.400,0:05:21.680 +and then shifting it by 12 bits mask + +0:05:20.800,0:05:24.000 +means the hd + +0:05:21.680,0:05:25.440 +performance binary end you can do the + +0:05:24.000,0:05:26.639 +same with the argument basement with + +0:05:25.440,0:05:29.520 +zero fff + +0:05:26.639,0:05:31.039 +and no shift if you do this long enough + +0:05:29.520,0:05:32.639 +you'll find common patterns for example + +0:05:31.039,0:05:35.280 +addresses are always encoded like this + +0:05:32.639,0:05:36.880 +using the last three nibbles in the code + +0:05:35.280,0:05:38.400 +you'll find a big count which dispatches + +0:05:36.880,0:05:40.070 +on the type and executes it for the side + +0:05:38.400,0:05:41.440 +effects + +0:05:40.070,0:05:43.440 +[Music] + +0:05:41.440,0:05:45.919 +for testing i've initially just accused + +0:05:43.440,0:05:47.280 +the rom until i fit ctrl g + +0:05:45.919,0:05:49.039 +and then use the debug command to run + +0:05:47.280,0:05:51.360 +the screen to a buffer + +0:05:49.039,0:05:52.320 +later on i found tiny roms that just + +0:05:51.360,0:05:55.680 +display a static + +0:05:52.320,0:05:57.280 +test screen for example logo and looked + +0:05:55.680,0:05:59.199 +whether it looked right + +0:05:57.280,0:06:00.960 +i added instructions as needed and went + +0:05:59.199,0:06:03.360 +through more and more and more roms and + +0:06:00.960,0:06:05.199 +later i wrote in unit test suite as a + +0:06:03.360,0:06:06.000 +safety net and this unit test suite it + +0:06:05.199,0:06:08.400 +just + +0:06:06.000,0:06:10.080 +sets up an empty emulator state executes + +0:06:08.400,0:06:10.400 +some instructions and then looks whether + +0:06:10.080,0:06:13.840 +the + +0:06:10.400,0:06:13.840 +expected side effects have happened + +0:06:14.880,0:06:19.120 +for debugging i usually use e-debug but + +0:06:17.120,0:06:20.880 +this was super ineffective because well + +0:06:19.120,0:06:22.960 +you don't really want to step through + +0:06:20.880,0:06:24.960 +big cons doing side effects for every + +0:06:22.960,0:06:26.880 +single cycle when it can take like 100 + +0:06:24.960,0:06:29.680 +cycles for things to happen + +0:06:26.880,0:06:31.360 +therefore i've set up logging and + +0:06:29.680,0:06:32.720 +whenever i locked something + +0:06:31.360,0:06:33.919 +and couldn't figure out the error i + +0:06:32.720,0:06:37.039 +compared my lock output with + +0:06:33.919,0:06:39.199 +instrumented version of another emulator + +0:06:37.039,0:06:40.880 +and if the locks diverge then i have + +0:06:39.199,0:06:42.720 +figured out where the bug lies and could + +0:06:40.880,0:06:44.479 +look deeper into it + +0:06:42.720,0:06:46.639 +future project idea might be a chip 8 + +0:06:44.479,0:06:50.720 +debugger but i doubt i'll ever + +0:06:46.639,0:06:52.639 +go into it for analysis i initially + +0:06:50.720,0:06:54.400 +wrote a disassembler which is a very + +0:06:52.639,0:06:56.160 +simple thing but super tedious + +0:06:54.400,0:06:57.599 +especially if you wanted to add advanced + +0:06:56.160,0:06:59.120 +functionality for example analysis or + +0:06:57.599,0:07:00.000 +thinking of what part is data what had + +0:06:59.120,0:07:01.840 +this code + +0:07:00.000,0:07:03.360 +and i had this great idea for using the + +0:07:01.840,0:07:05.120 +radari 2 framework + +0:07:03.360,0:07:06.479 +and adding analysis and disassembly + +0:07:05.120,0:07:08.400 +plug-in for it + +0:07:06.479,0:07:10.319 +so i looked into this found okay here + +0:07:08.400,0:07:12.160 +where you can write plugins in c + +0:07:10.319,0:07:13.520 +but also in python so i wrote one in + +0:07:12.160,0:07:15.039 +python and then the scout there's + +0:07:13.520,0:07:17.440 +actually existing one in core which you + +0:07:15.039,0:07:19.599 +have to enable explicitly by passing its + +0:07:17.440,0:07:21.840 +argument so i've tried it and found it's + +0:07:19.599,0:07:23.680 +not exactly as good as my own one so + +0:07:21.840,0:07:26.610 +improved this one and submitted pull + +0:07:23.680,0:07:28.080 +requests until it was at the same level + +0:07:26.610,0:07:30.160 +[Music] + +0:07:28.080,0:07:31.360 +rendering was the trickiest part of this + +0:07:30.160,0:07:34.319 +whole thing because + +0:07:31.360,0:07:35.759 +well i decided against using a library + +0:07:34.319,0:07:37.120 +not like there would have been any + +0:07:35.759,0:07:39.599 +usable library for this + +0:07:37.120,0:07:41.680 +my usual approach of accelerating svg + +0:07:39.599,0:07:45.120 +file was too expensive it just created + +0:07:41.680,0:07:47.360 +too much garbage and took too long time + +0:07:45.120,0:07:49.599 +i then tried creating mutating strings + +0:07:47.360,0:07:52.639 +this was either either too expensive + +0:07:49.599,0:07:55.039 +just like svgs or too complicated i + +0:07:52.639,0:07:57.280 +tried changing svg tiles which created + +0:07:55.039,0:07:59.520 +gaps between the lines + +0:07:57.280,0:08:00.720 +then i tried to create an xpm file which + +0:07:59.520,0:08:02.400 +was backed by a bull vector + +0:08:00.720,0:08:04.400 +administrating this bull vector + +0:08:02.400,0:08:06.879 +but the image caching effect made it + +0:08:04.400,0:08:10.000 +just every nth frame to appear which + +0:08:06.879,0:08:11.440 +wasn't good either then i had the idea + +0:08:10.000,0:08:13.280 +to just use plain text + +0:08:11.440,0:08:14.800 +and paint the individual characters with + +0:08:13.280,0:08:17.120 +a different background color this + +0:08:14.800,0:08:18.479 +this had perfect perfect performance + +0:08:17.120,0:08:20.000 +there were many optimization attempts + +0:08:18.479,0:08:21.840 +until i got there and it was + +0:08:20.000,0:08:23.199 +very very stressful i wasn't sure + +0:08:21.840,0:08:26.160 +whether i would ever get to accept the + +0:08:23.199,0:08:28.560 +performance at all + +0:08:26.160,0:08:30.319 +for sound you only need to a single beep + +0:08:28.560,0:08:31.280 +so technically it shouldn't be difficult + +0:08:30.319,0:08:33.519 +to emulate it + +0:08:31.280,0:08:34.880 +however doing this is hard because emacs + +0:08:33.519,0:08:37.200 +officially only supports synchronous + +0:08:34.880,0:08:39.039 +playback of sounds + +0:08:37.200,0:08:41.360 +but there's also emax process which you + +0:08:39.039,0:08:43.519 +can launch in asynchronous way + +0:08:41.360,0:08:45.279 +so i looked into it and found that + +0:08:43.519,0:08:46.640 +employee has a slave mode and mpv + +0:08:45.279,0:08:50.880 +supports listing on the + +0:08:46.640,0:08:54.000 +fifo for commands so i've created a pipe + +0:08:50.880,0:08:55.519 +started a past mpv in loop mode and + +0:08:54.000,0:08:58.000 +always send in pause and pause command + +0:08:55.519,0:09:01.839 +to the fifo and that way i could control + +0:08:58.000,0:09:01.839 +when to start beeping and stop beeping + +0:09:02.640,0:09:07.200 +so yeah that's it so far was a very + +0:09:05.760,0:09:09.279 +educational experience + +0:09:07.200,0:09:10.320 +i have tried out a bunch of games which + +0:09:09.279,0:09:12.640 +were + +0:09:10.320,0:09:14.320 +well i almost say the worst ports of + +0:09:12.640,0:09:15.839 +classic games i've ever tried + +0:09:14.320,0:09:18.320 +it wasn't terribly fun to play them but + +0:09:15.839,0:09:21.760 +was fun to improve the emulator until + +0:09:18.320,0:09:23.279 +well things worked good enough + +0:09:21.760,0:09:25.120 +and i've learned a lot about how + +0:09:23.279,0:09:27.760 +computers work at this level + +0:09:25.120,0:09:28.880 +so maybe maybe i'll in the future make + +0:09:27.760,0:09:31.920 +another emulator + +0:09:28.880,0:09:34.000 +but uh i'm not sure whether anything + +0:09:31.920,0:09:36.560 +more advanced like intel 8080 emulator + +0:09:34.000,0:09:37.839 +will actually run mix fast enough + +0:09:36.560,0:09:39.200 +but it's still an interesting idea + +0:09:37.839,0:09:39.600 +because then you could actually have an + +0:09:39.200,0:09:41.680 +os + +0:09:39.600,0:09:43.120 +inside emacs and fulfill that one + +0:09:41.680,0:09:45.440 +specific meme + +0:09:43.120,0:09:47.279 +but if i try to do most serious stuff + +0:09:45.440,0:09:48.000 +i'll probably use chicken scheme which + +0:09:47.279,0:09:49.920 +is my + +0:09:48.000,0:09:53.279 +preferred language for serious projects + +0:09:49.920,0:09:57.839 +and

title of the stock is a tour feature + +0:00:06.080,0:00:08.559 +a fast and fully featured terminal + +0:00:07.919,0:00:11.840 +emulator + +0:00:08.559,0:00:13.360 +inside new e-max so let's try to + +0:00:11.840,0:00:14.559 +understand what we mean with the pass + +0:00:13.360,0:00:17.520 +and fully featured + +0:00:14.559,0:00:18.320 +and to do that we'll compare v term with + +0:00:17.520,0:00:20.640 +the + +0:00:18.320,0:00:22.400 +packages which are built in emacs mean + +0:00:20.640,0:00:25.199 +the term + +0:00:22.400,0:00:26.720 +so let's let's jump into the v term so + +0:00:25.199,0:00:29.679 +this is a feature buffer + +0:00:26.720,0:00:31.519 +and this is a ansi term buffer what i'm + +0:00:29.679,0:00:32.160 +going to do now is first i'm going to + +0:00:31.519,0:00:35.760 +prove you + +0:00:32.160,0:00:37.520 +what we move fast so to do that let me + +0:00:35.760,0:00:39.280 +open a large file display on screen or + +0:00:37.520,0:00:40.239 +large file this is about one megabyte of + +0:00:39.280,0:00:43.520 +data + +0:00:40.239,0:00:44.160 +and let me time that it takes about 0.6 + +0:00:43.520,0:00:47.200 +seconds + +0:00:44.160,0:00:49.760 +with feature let's do the same with + +0:00:47.200,0:00:51.520 +with ancient term well we already + +0:00:49.760,0:00:53.039 +already see the difference + +0:00:51.520,0:00:54.559 +so i will use this time to tell you + +0:00:53.039,0:00:57.360 +what's different and + +0:00:54.559,0:00:58.879 +what is v term exactly so v term is a + +0:00:57.360,0:01:01.120 +terminal emulator built + +0:00:58.879,0:01:02.719 +on top of an external library the + +0:01:01.120,0:01:05.519 +library is called libvi term + +0:01:02.719,0:01:07.200 +and is the same library used by newton + +0:01:05.519,0:01:10.000 +for their own terminal emulator + +0:01:07.200,0:01:10.799 +it's a c library and this is what gives + +0:01:10.000,0:01:15.119 +us + +0:01:10.799,0:01:17.280 +a lot of good features first the speed + +0:01:15.119,0:01:18.479 +time spent here 0.6 is essentially the + +0:01:17.280,0:01:21.520 +time that it takes to + +0:01:18.479,0:01:22.240 +one convert the emax representation of + +0:01:21.520,0:01:23.840 +like text + +0:01:22.240,0:01:26.400 +into the visa and representation of what + +0:01:23.840,0:01:28.479 +was a string and two into + +0:01:26.400,0:01:29.520 +actually displaying that and that can + +0:01:28.479,0:01:31.840 +take time + +0:01:29.520,0:01:33.680 +if there's a if there's quantification + +0:01:31.840,0:01:34.240 +involved so these are the 0.6 seconds + +0:01:33.680,0:01:36.960 +there + +0:01:34.240,0:01:37.920 +as we say in the in ancestor that's much + +0:01:36.960,0:01:39.920 +much + +0:01:37.920,0:01:41.680 +more time it's much slower so the + +0:01:39.920,0:01:42.880 +terminal will feel much snappier much + +0:01:41.680,0:01:46.079 +faster + +0:01:42.880,0:01:47.840 +but that's not the main benefit or the + +0:01:46.079,0:01:48.799 +only benefit of using this external + +0:01:47.840,0:01:52.320 +library + +0:01:48.799,0:01:55.439 +feature the second big benefit + +0:01:52.320,0:01:56.560 +is that v term has support for all the + +0:01:55.439,0:01:59.200 +escape codes + +0:01:56.560,0:02:01.119 +that exterm has support for so v term is + +0:01:59.200,0:02:03.600 +essentially as running x term + +0:02:01.119,0:02:04.799 +inside an imax buffer so let's see that + +0:02:03.600,0:02:07.119 +this for example + +0:02:04.799,0:02:08.239 +let's start by looking at the support + +0:02:07.119,0:02:09.920 +for colors + +0:02:08.239,0:02:11.840 +we have support for all the colors out + +0:02:09.920,0:02:15.040 +of the box we don't have to do anything + +0:02:11.840,0:02:15.680 +and if we did the same here well we have + +0:02:15.040,0:02:17.920 +only + +0:02:15.680,0:02:19.680 +20 colors there's a way to get all the + +0:02:17.920,0:02:23.040 +colors but it's much more involved + +0:02:19.680,0:02:26.000 +but this is not where v term shines + +0:02:23.040,0:02:27.200 +uh we can run all the commands that we + +0:02:26.000,0:02:30.480 +want + +0:02:27.200,0:02:33.040 +h top and cdu + +0:02:30.480,0:02:33.840 +everything runs here also this title + +0:02:33.040,0:02:36.400 +it's a + +0:02:33.840,0:02:37.040 +it's a fairly complicated manipulation + +0:02:36.400,0:02:40.879 +of + +0:02:37.040,0:02:42.319 +the window and it will not work here + +0:02:40.879,0:02:44.640 +it just doesn't work actually now the + +0:02:42.319,0:02:48.400 +terminal is probably messed up + +0:02:44.640,0:02:50.959 +yes so using this external library + +0:02:48.400,0:02:52.000 +removes the burden from the developers + +0:02:50.959,0:02:54.000 +of having to implement + +0:02:52.000,0:02:55.360 +support for all these cape codes we just + +0:02:54.000,0:02:58.480 +use those + +0:02:55.360,0:03:01.760 +so in many ways running veteran + +0:02:58.480,0:03:04.400 +is us running extern inside a max + +0:03:01.760,0:03:05.840 +but it's better than that because since + +0:03:04.400,0:03:08.879 +this is an e-max buffer + +0:03:05.840,0:03:09.760 +we can enjoy a lot of features from + +0:03:08.879,0:03:11.920 +emacs + +0:03:09.760,0:03:13.200 +as well as a tighter integration with + +0:03:11.920,0:03:16.560 +e-max itself + +0:03:13.200,0:03:17.599 +for example as you see here the title of + +0:03:16.560,0:03:20.720 +my buffer + +0:03:17.599,0:03:21.760 +is from the director i'm in so let's go + +0:03:20.720,0:03:24.799 +to my tmp + +0:03:21.760,0:03:26.560 +the title will change so there's + +0:03:24.799,0:03:28.000 +information being exchanged between v + +0:03:26.560,0:03:29.760 +term and index + +0:03:28.000,0:03:32.000 +and of course the title is not the only + +0:03:29.760,0:03:34.799 +place where information is exchanged + +0:03:32.000,0:03:35.920 +i can find a file and i will be in the + +0:03:34.799,0:03:38.239 +directory + +0:03:35.920,0:03:40.000 +where my terminal is this feature is + +0:03:38.239,0:03:41.680 +also available in nc term + +0:03:40.000,0:03:43.840 +and it works also on b term and it + +0:03:41.680,0:03:44.720 +follows me so if i go to tmp i'll get + +0:03:43.840,0:03:48.000 +the tmp + +0:03:44.720,0:03:48.640 +if i ssh to a remote server it will work + +0:03:48.000,0:03:51.120 +also + +0:03:48.640,0:03:53.920 +on remote servers as well which is a + +0:03:51.120,0:03:55.760 +very nice way to edit files remotely + +0:03:53.920,0:03:57.360 +while we're working on a shelf and + +0:03:55.760,0:03:59.599 +second while vterm + +0:03:57.360,0:04:02.159 +is not an e-lisp interpreter like + +0:03:59.599,0:04:06.080 +initial what we can do is we can + +0:04:02.159,0:04:08.319 +still run inbox functions so for example + +0:04:06.080,0:04:10.159 +that requires some configuration the + +0:04:08.319,0:04:12.480 +term + +0:04:10.159,0:04:14.000 +command message i as you see there's a + +0:04:12.480,0:04:16.239 +higher so what i'm doing + +0:04:14.000,0:04:17.199 +is i'm executing the eagles function i + +0:04:16.239,0:04:19.840 +and i can drop that + +0:04:17.199,0:04:20.320 +and turn it around uh hash function to + +0:04:19.840,0:04:24.880 +run + +0:04:20.320,0:04:27.600 +a-list functions or another one file see + +0:04:24.880,0:04:28.800 +we call this feature message passing and + +0:04:27.600,0:04:30.880 +it requires + +0:04:28.800,0:04:32.000 +some configuration on the emac side as + +0:04:30.880,0:04:34.000 +well as in the shell side + +0:04:32.000,0:04:35.360 +it's important to stress what's the + +0:04:34.000,0:04:37.360 +nature of feature + +0:04:35.360,0:04:39.120 +for instance every time i'm sending a + +0:04:37.360,0:04:40.800 +key binding it's not immediately clear + +0:04:39.120,0:04:42.720 +if my intention is to send it to the + +0:04:40.800,0:04:44.320 +shell or to imax so v term implements + +0:04:42.720,0:04:46.800 +some reasonable defaults + +0:04:44.320,0:04:49.120 +but at the moment it's mainly packaged + +0:04:46.800,0:04:51.199 +to display characters on a screen + +0:04:49.120,0:04:53.600 +so for example if you're using evil the + +0:04:51.199,0:04:55.759 +editing commands in evil will not work + +0:04:53.600,0:04:57.840 +immediately there's some work to be done + +0:04:55.759,0:04:58.479 +and integration can be improved on that + +0:04:57.840,0:05:00.240 +side but + +0:04:58.479,0:05:02.240 +sometimes we really want this to behave + +0:05:00.240,0:05:05.440 +exactly like a imax buffer + +0:05:02.240,0:05:07.039 +we want to be able to search if + +0:05:05.440,0:05:08.880 +if i try to get it to search it will not + +0:05:07.039,0:05:09.360 +work i will send it to the shop so to do + +0:05:08.880,0:05:12.400 +that + +0:05:09.360,0:05:12.800 +we enabled the term copy mode so as you + +0:05:12.400,0:05:15.280 +see + +0:05:12.800,0:05:17.039 +copy mode and now this buffer is + +0:05:15.280,0:05:21.120 +essentially a fundamental buffer + +0:05:17.039,0:05:24.400 +i can move around as i can search + +0:05:21.120,0:05:25.840 +uh so it must have i + +0:05:24.400,0:05:27.120 +can do everything i want and there are + +0:05:25.840,0:05:29.600 +additional features for example i can + +0:05:27.120,0:05:31.440 +jump around + +0:05:29.600,0:05:32.639 +all the prompts and i find this + +0:05:31.440,0:05:34.400 +extremely useful + +0:05:32.639,0:05:35.919 +because i can copy update from my + +0:05:34.400,0:05:39.199 +programs or + +0:05:35.919,0:05:42.400 +what i always have to do is i have to + +0:05:39.199,0:05:43.120 +google some errors so what i do is i + +0:05:42.400,0:05:45.919 +select that + +0:05:43.120,0:05:46.880 +and i have my keybinding in maksakov and + +0:05:45.919,0:05:49.199 +i'm googling + +0:05:46.880,0:05:50.400 +what i have to google so this is very + +0:05:49.199,0:05:52.800 +nice and + +0:05:50.400,0:05:54.400 +if i now that have selected something if + +0:05:52.800,0:05:57.120 +i just press return i will + +0:05:54.400,0:05:57.440 +go back to my normal editing mode with + +0:05:57.120,0:06:00.400 +the + +0:05:57.440,0:06:01.600 +text copied so i can paste it back so + +0:06:00.400,0:06:04.160 +it's a quick way to + +0:06:01.600,0:06:06.400 +interact with copy and interact with uh + +0:06:04.160,0:06:07.840 +with the output of a buffer so finally + +0:06:06.400,0:06:10.560 +let's discuss how to actually + +0:06:07.840,0:06:12.400 +use beta let's circle back and let's go + +0:06:10.560,0:06:14.400 +and let's look at the github

+0:06:17.919,0:06:20.639 +an external module + +0:06:18.960,0:06:22.000 +you must have emacs compiled with + +0:06:20.639,0:06:25.600 +support for modules + +0:06:22.000,0:06:27.199 +and many distros like ubuntu debian + +0:06:25.600,0:06:29.840 +that's not there so you have to get + +0:06:27.199,0:06:30.160 +emacs with support for modules compiling + +0:06:29.840,0:06:32.000 +or + +0:06:30.160,0:06:33.840 +getting images somewhere else and also + +0:06:32.000,0:06:34.400 +the first time you are going to use this + +0:06:33.840,0:06:37.440 +which + +0:06:34.400,0:06:40.319 +works only on mac or + +0:06:37.440,0:06:41.759 +new linux systems emacs will try to find + +0:06:40.319,0:06:43.680 +and compile this module + +0:06:41.759,0:06:45.440 +so it's important this requirement is + +0:06:43.680,0:06:47.600 +important if you're using windows + +0:06:45.440,0:06:49.199 +well that's not it's not available and + +0:06:47.600,0:06:52.560 +will not work + +0:06:49.199,0:06:53.440 +so to conclude i want to just advertise + +0:06:52.560,0:06:56.240 +this page + +0:06:53.440,0:06:57.120 +if you have problems look at the issues + +0:06:56.240,0:06:59.039

questions on the user product + +0:00:22.800,0:00:27.039 +i'm going to answer + +0:00:24.000,0:00:29.039 +them okay so the first one is + +0:00:27.039,0:00:31.119 +can you put your test space from up + +0:00:29.039,0:00:31.840 +somewhere uh yes they're very simple + +0:00:31.119,0:00:33.680 +skips + +0:00:31.840,0:00:35.520 +uh i'll find a way to distribute them + +0:00:33.680,0:00:37.600 +somehow + +0:00:35.520,0:00:38.800 +that's so that's an easy one the second + +0:00:37.600,0:00:40.559 +one is more difficult it's more + +0:00:38.800,0:00:44.320 +difficult it's the differences between + +0:00:40.559,0:00:47.360 +e shell and v term so i did very basic + +0:00:44.320,0:00:50.399 +level the main difference is that v + +0:00:47.360,0:00:52.800 +term is implemented with + +0:00:50.399,0:00:53.840 +as a bridge between emacs and an + +0:00:52.800,0:00:56.079 +external library + +0:00:53.840,0:00:57.039 +which means that most of the code base + +0:00:56.079,0:01:00.320 +is actually c + +0:00:57.039,0:01:01.280 +it's not easy uh this is is a critical + +0:01:00.320,0:01:03.760 +difference + +0:01:01.280,0:01:04.320 +uh in terms of performance in terms of + +0:01:03.760,0:01:06.960 +speed + +0:01:04.320,0:01:07.360 +and all the other uh features that we + +0:01:06.960,0:01:10.400 +can + +0:01:07.360,0:01:13.119 +inherit from this library so vterm + +0:01:10.400,0:01:13.600 +is similar to a real terminal it's not + +0:01:13.119,0:01:15.840 +as + +0:01:13.600,0:01:17.040 +uh it's not like a shell it's a real + +0:01:15.840,0:01:19.600 +terminal emulator + +0:01:17.040,0:01:20.479 +that can actually uh display but + +0:01:19.600,0:01:22.960 +manipulate the + +0:01:20.479,0:01:23.520 +terminal in pretty much any way whereas + +0:01:22.960,0:01:25.759 +isha + +0:01:23.520,0:01:26.640 +is simply a way to interact with your + +0:01:25.759,0:01:29.680 +system + +0:01:26.640,0:01:31.840 +in the data page we have a more + +0:01:29.680,0:01:33.520 +complete discussion about this topic and + +0:01:31.840,0:01:34.799 +where we compare v-terms with e-shell + +0:01:33.520,0:01:38.720 +with shell with nc + +0:01:34.799,0:01:40.640 +term as well i think so + +0:01:38.720,0:01:42.000 +i think just to conclude this i think + +0:01:40.640,0:01:44.079 +eshell and v term + +0:01:42.000,0:01:45.280 +are somehow orthogonal in the sense that + +0:01:44.079,0:01:46.880 +v3 is before a + +0:01:45.280,0:01:49.439 +full complete terminal experience + +0:01:46.880,0:01:50.240 +whereas isil is more for specific tasks + +0:01:49.439,0:01:53.280 +of this + +0:01:50.240,0:01:55.759 +uh which are not like terminal uh + +0:01:53.280,0:01:56.799 +interfaces you know like page stock this + +0:01:55.759,0:01:59.759 +kind of stuff + +0:01:56.799,0:02:01.200 +uh the next question is uh is there a + +0:01:59.759,0:02:02.560 +plan to avoid compilation of the initial + +0:02:01.200,0:02:05.759 +completion steps + +0:02:02.560,0:02:08.000 +so since the term is based on again + +0:02:05.759,0:02:08.800 +on an external module we need to combine + +0:02:08.000,0:02:10.800 +this module + +0:02:08.800,0:02:11.920 +and we're using the dynamic module + +0:02:10.800,0:02:13.920 +system to + +0:02:11.920,0:02:16.239 +be able to interface with this module + +0:02:13.920,0:02:18.879 +and this requires + +0:02:16.239,0:02:20.160 +us to compile the module at least the + +0:02:18.879,0:02:23.920 +very first time you start + +0:02:20.160,0:02:26.720 +the i don't think we can do + +0:02:23.920,0:02:28.480 +without that in the near future we need + +0:02:26.720,0:02:31.599 +to compile this + +0:02:28.480,0:02:33.360 +and we must there's no way around + +0:02:31.599,0:02:36.720 +if we cannot simply distribute the + +0:02:33.360,0:02:36.720 +module um + +0:02:37.440,0:02:40.480 +if you want to think very long term + +0:02:39.519,0:02:42.959 +maybe + +0:02:40.480,0:02:43.599 +uh but i think there's no current plan + +0:02:42.959,0:02:45.760 +to + +0:02:43.599,0:02:47.280 +avoid the compilation as the very first + +0:02:45.760,0:02:50.400 +step the first time you + +0:02:47.280,0:02:50.959 +uh run vtor however all the subsequent + +0:02:50.400,0:02:54.720 +times + +0:02:50.959,0:02:57.840 +you will not have to compile peter um + +0:02:54.720,0:02:58.720 +so for question four it's uh i have a + +0:02:57.840,0:03:01.920 +nice looking problem + +0:02:58.720,0:03:04.159 +thanks uh and if + +0:03:01.920,0:03:05.599 +there's a git repo where you can see it + +0:03:04.159,0:03:08.560 +or something like that + +0:03:05.599,0:03:09.760 +so if you go to my github repo i have + +0:03:08.560,0:03:12.560 +adobe files + +0:03:09.760,0:03:13.840 +repo but look at that it's terrible it's + +0:03:12.560,0:03:16.800 +super updated + +0:03:13.840,0:03:17.519 +so i've been meaning to polish it for + +0:03:16.800,0:03:20.080 +like years + +0:03:17.519,0:03:21.760 +and i haven't got it so don't look at it + +0:03:20.080,0:03:25.200 +my font is actually extremely simple + +0:03:21.760,0:03:26.640 +i think it's the pure prompt from uh zsh + +0:03:25.200,0:03:28.799 +or fish depending + +0:03:26.640,0:03:30.640 +uh and i think i didn't do anything but + +0:03:28.799,0:03:31.360 +like maybe tweaking the colors a little + +0:03:30.640,0:03:33.280 +bit + +0:03:31.360,0:03:35.519 +okay gabriel just sorry to interject if + +0:03:33.280,0:03:37.120 +you could just take one more question + +0:03:35.519,0:03:39.440 +yes the last question is already the + +0:03:37.120,0:03:42.480 +answer which is uh will it work with + +0:03:39.440,0:03:44.480 +e max terminal so minus and w and answer + +0:03:42.480,0:03:46.239 +yes it works without any problem with + +0:03:44.480,0:03:47.760 +imax terminal so you can run a terminal + +0:03:46.239,0:03:49.680 +inside image inside of terminal + +0:03:47.760,0:03:51.200 +and you can continue paying up as much + +0:03:49.680,0:03:53.920 +as you want okay + +0:03:51.200,0:03:56.239 +i think that's it explain the question + +0:03:53.920,0:03:59.760 +oh sorry thank you + +0:03:56.239,0:04:01.519 +thanks for attending this talk + +0:03:59.760,0:04:03.360 +well thank you so much for giving it so + +0:04:01.519,0:04:07.280

roughly 10 us states and parts + +0:01:03.120,0:01:08.479 +of canada and so this language is + +0:01:05.199,0:01:10.880 +spoken over a wide range of of + +0:01:08.479,0:01:10.880 +area +

+0:02:12.160,0:02:15.520 +point probably the only time i'd heard + +0:02:13.840,0:02:18.720 +the lakota language was in + +0:02:15.520,0:02:20.720 +the movie dances with wolves possibly +

+close to + +0:02:28.319,0:02:32.239 +to lakota people and other native + +0:02:30.560,0:02:34.560 +american people + +0:02:32.239,0:02:36.640 +american indian people i kind of thought + +0:02:34.560,0:02:39.760 +it was just dead i thought the language + +0:02:36.640,0:02:42.000 +was not alive anymore um + +0:02:39.760,0:02:43.920 +but in 2016 my daughter began her +

+0:02:48.239,0:02:51.920 +you know not knowing my family not + +0:02:50.560,0:02:54.080 +knowing my culture + +0:02:51.920,0:02:55.280 +what could i do to try to bring that + +0:02:54.080,0:02:58.640 +into our life + +0:02:55.280,0:03:00.720 +um and so i found out about these + +0:02:58.640,0:03:02.720 +lakota classes that were happening i + +0:03:00.720,0:03:04.560 +went up to standing rock + +0:03:02.720,0:03:06.640 +in north dakota and attended the lakota + +0:03:04.560,0:03:08.480 +summer institute for three weeks + +0:03:06.640,0:03:09.680 +and began my journey to learn the + +0:03:08.480,0:03:13.120 +language so i can + +0:03:09.680,0:03:16.400 +try to pass it on so + +0:03:13.120,0:03:16.400 +this brings us to emacs + +0:03:16.560,0:03:20.959 +i could talk a lot more about my story + +0:03:19.200,0:03:24.640 +i'm sure there's a lot to say + +0:03:20.959,0:03:26.319 +but we're here to talk about emacs um + +0:03:24.640,0:03:29.040 +i was already a free software user at + +0:03:26.319,0:03:31.440 +the time and at the lakota language + +0:03:29.040,0:03:33.280 +uh institute they they were they're + +0:03:31.440,0:03:34.879 +giving us software there's a dictionary + +0:03:33.280,0:03:37.360 +you could get on android + +0:03:34.879,0:03:38.560 +um there was a keyboard for android that + +0:03:37.360,0:03:41.760 +you could type with + +0:03:38.560,0:03:44.959 +they had keyboard input methods for mac + +0:03:41.760,0:03:46.720 +and windows but i'm a linux user free + +0:03:44.959,0:03:49.280 +software user + +0:03:46.720,0:03:49.760 +so i didn't have access to those things + +0:03:49.280,0:03:53.120 +as + +0:03:49.760,0:03:55.280 +as easily as i could and i do a lot of + +0:03:53.120,0:03:57.280 +my thinking and note taking in emacs and + +0:03:55.280,0:04:01.200 +in org mode + +0:03:57.280,0:04:04.640 +and so being able to to write this + +0:04:01.200,0:04:07.680 +to to um to write things down to type + +0:04:04.640,0:04:08.720 +on my own computer uh was was pretty + +0:04:07.680,0:04:11.360 +important to me + +0:04:08.720,0:04:12.799 +and i wasn't much of an emax hacker yet + +0:04:11.360,0:04:15.519 +at the time i had + +0:04:12.799,0:04:16.720 +barely done anything mostly just you + +0:04:15.519,0:04:20.479 +know hacked on my + +0:04:16.720,0:04:23.600 +config file but this was a real + +0:04:20.479,0:04:27.280 +chance for me to experience + +0:04:23.600,0:04:30.400 +the the benefits of free software first + +0:04:27.280,0:04:33.680 +hand and not just to benefit myself but + +0:04:30.400,0:04:33.680 +to potentially benefit + +0:04:34.080,0:04:38.800 +everyone anyone interested in learning + +0:04:36.080,0:04:38.800 +this language + +0:04:39.120,0:04:44.880 +so emacs and + +0:04:42.880,0:04:47.520 +that free software philosophy really + +0:04:44.880,0:04:49.840 +empowered me so i began digging in + +0:04:47.520,0:04:51.520 +um i looked i began reading the the + +0:04:49.840,0:04:53.680 +manual more closely + +0:04:51.520,0:04:55.440 +as an american i'm i'm sad to say + +0:04:53.680,0:04:58.479 +there's not a lot of + +0:04:55.440,0:05:00.160 +other languages spoken or written where + +0:04:58.479,0:05:02.240 +i'm from + +0:05:00.160,0:05:04.720 +so it's not common that i that i have to + +0:05:02.240,0:05:07.600 +think about this with computers + +0:05:04.720,0:05:09.120 +i know international people you know + +0:05:07.600,0:05:11.280 +have had to come up with + +0:05:09.120,0:05:12.160 +with interesting ways to to enter their + +0:05:11.280,0:05:14.800 +text + +0:05:12.160,0:05:16.320 +and emacs is probably a pioneer in that + +0:05:14.800,0:05:17.520 +i i'd like to know more about the + +0:05:16.320,0:05:19.840 +history of this but + +0:05:17.520,0:05:22.160 +there's a whole section in the manual on + +0:05:19.840,0:05:23.840 +international emacs + +0:05:22.160,0:05:25.440 +and i began reading this and i was + +0:05:23.840,0:05:28.000 +talking about + +0:05:25.440,0:05:29.759 +different input methods and and how many + +0:05:28.000,0:05:31.680 +different languages were supported and + +0:05:29.759,0:05:33.680 +how you could enter the text and how it + +0:05:31.680,0:05:34.560 +supports the different characters and so + +0:05:33.680,0:05:36.639 +on + +0:05:34.560,0:05:38.880 +um i even noticed a few languages + +0:05:36.639,0:05:41.840 +support several input methods + +0:05:38.880,0:05:43.440 +that became important for me later on as + +0:05:41.840,0:05:45.280 +i was working on this + +0:05:43.440,0:05:46.720 +many many languages are already + +0:05:45.280,0:05:48.479 +supported so + +0:05:46.720,0:05:50.080 +those of you who haven't looked into + +0:05:48.479,0:05:52.639 +this yet if you press + +0:05:50.080,0:05:53.680 +control backslash it will open up a + +0:05:52.639,0:05:57.039 +selection menu + +0:05:53.680,0:05:59.120 +for you to to select um + +0:05:57.039,0:06:01.440 +your input method and you can there's + +0:05:59.120,0:06:03.120 +207 listed here + +0:06:01.440,0:06:04.639 +that's including the two that i've + +0:06:03.120,0:06:09.199 +contributed + +0:06:04.639,0:06:11.120 +um so 205 on on a vanilla emacs + +0:06:09.199,0:06:13.840 +so that's a lot of languages supported + +0:06:11.120,0:06:17.440 +by emac emacs but there's so many more + +0:06:13.840,0:06:19.280 +that could be um and since emacs is free + +0:06:17.440,0:06:20.000 +software and it is what it is i knew + +0:06:19.280,0:06:22.639 +that defining + +0:06:20.000,0:06:23.039 +a new input method was surely possible + +0:06:22.639,0:06:25.440 +um + +0:06:23.039,0:06:27.120 +unfortunately the the manual didn't + +0:06:25.440,0:06:28.800 +describe it directly or at least i + +0:06:27.120,0:06:30.960 +didn't pick it up so + +0:06:28.800,0:06:32.319 +um you know the new emax hacker that i + +0:06:30.960,0:06:34.880 +was i + +0:06:32.319,0:06:37.360 +i timidly dove down into the source code + +0:06:34.880,0:06:40.479 +and discovered the quail package + +0:06:37.360,0:06:40.960 +um so back in the day apparently there + +0:06:40.479,0:06:44.240 +was + +0:06:40.960,0:06:44.240 +mule which is like the + +0:06:44.560,0:06:48.000 +multi i don't i don't know it stood for + +0:06:47.360,0:06:50.160 +something about + +0:06:48.000,0:06:51.759 +language environments and and it has + +0:06:50.160,0:06:54.960 +evolved + +0:06:51.759,0:06:58.000 +and at some point um some japanese + +0:06:54.960,0:06:59.039 +uh coders created an input method called + +0:06:58.000,0:07:03.599 +tamago + +0:06:59.039,0:07:06.720 +which means egg in japanese and uh + +0:07:03.599,0:07:08.800 +tamago evolved into quail and they + +0:07:06.720,0:07:10.720 +in the comments you can see they talk + +0:07:08.800,0:07:12.800 +about how the quail egg is eaten in + +0:07:10.720,0:07:15.280 +japan it's a smaller thing and + +0:07:12.800,0:07:16.960 +the quail mode is like a nicer version + +0:07:15.280,0:07:19.039 +of tamago i guess and + +0:07:16.960,0:07:22.639 +there's a pun saying they hoped it would + +0:07:19.039,0:07:26.240 +egg people on to create more input modes + +0:07:22.639,0:07:28.479 +and quail is quite nice i looked into it + +0:07:26.240,0:07:30.720 +and there's basically two things you use + +0:07:28.479,0:07:32.240 +quail defined package and quail define + +0:07:30.720,0:07:35.759 +rules + +0:07:32.240,0:07:35.759 +so quail defined package + +0:07:36.080,0:07:41.759 +you can see here is a function it's + +0:07:38.960,0:07:43.599 +probably a macro that takes a name + +0:07:41.759,0:07:44.879 +a language a title and some optional + +0:07:43.599,0:07:48.080 +stuff which + +0:07:44.879,0:07:48.080 +i didn't really have to deal with + +0:07:48.319,0:07:52.400 +define name is a new quail package for + +0:07:50.479,0:07:52.879 +input language title is a string to be + +0:07:52.400,0:07:54.400 +split + +0:07:52.879,0:07:56.800 +at the mode line to indicate this + +0:07:54.400,0:07:56.800 +package + +0:07:57.120,0:08:03.039 +so i began trying to do lakota input now + +0:08:00.879,0:08:04.240 +this is a whole thing on its own because + +0:08:03.039,0:08:07.680 +the lakota language + +0:08:04.240,0:08:10.800 +was never written um + +0:08:07.680,0:08:12.879 +pre-contact and post contact + +0:08:10.800,0:08:14.800 +like there's several attempts at writing + +0:08:12.879,0:08:16.960 +it and different orthographies + +0:08:14.800,0:08:19.199 +and there's drama around all of this + +0:08:16.960,0:08:19.199 +stuff + +0:08:19.360,0:08:24.160 +it's pretty common to have drama going + +0:08:21.120,0:08:26.560 +on in any american indian stuff + +0:08:24.160,0:08:28.479 +going on so as i was doing this i + +0:08:26.560,0:08:29.680 +started with the suggested lakota + +0:08:28.479,0:08:32.880 +orthography which + +0:08:29.680,0:08:35.680 +is actually called by its authors the + +0:08:32.880,0:08:36.959 +the standard lakota orthography but its + +0:08:35.680,0:08:40.880 +authors are + +0:08:36.959,0:08:43.039 +um are european + +0:08:40.880,0:08:45.040 +um the main author is a man named jan + +0:08:43.039,0:08:46.160 +ulrich and i appreciate all his work and + +0:08:45.040,0:08:49.360 +i'm grateful for + +0:08:46.160,0:08:51.040 +the materials he's made available but um + +0:08:49.360,0:08:54.160 +it's a little bit problematic because + +0:08:51.040,0:08:56.720 +it's not an orthography created by + +0:08:54.160,0:08:57.920 +our people by lakota people so there's + +0:08:56.720,0:09:00.080 +another one called the white hat + +0:08:57.920,0:09:01.839 +orthography which is created by albert + +0:09:00.080,0:09:04.480 +whitehat who's a teacher + +0:09:01.839,0:09:05.360 +um from the chichanguk tribe so i + +0:09:04.480,0:09:08.640 +created two + +0:09:05.360,0:09:10.720 +and thankfully emax lets me do that so + +0:09:08.640,0:09:11.680 +it's pretty simple quail defined package + +0:09:10.720,0:09:13.279 +i just + +0:09:11.680,0:09:15.360 +say the package i want and then all + +0:09:13.279,0:09:16.480 +these nils and t's for options i don't + +0:09:15.360,0:09:18.240 +actually know what they mean but it + +0:09:16.480,0:09:20.240 +works + +0:09:18.240,0:09:22.640 +i could look it up and then quail define + +0:09:20.240,0:09:23.600 +rules just defines mappings from ascii + +0:09:22.640,0:09:26.640 +keys to + +0:09:23.600,0:09:29.680 +the the text you want to put in so + +0:09:26.640,0:09:33.600 +for this one there's a nasal n and then + +0:09:29.680,0:09:36.640 +a dot and a macron like a wedge shape + +0:09:33.600,0:09:39.839 +for marking up the consonants + +0:09:36.640,0:09:41.760 +so that one's pretty easy and then the + +0:09:39.839,0:09:43.040 +suggested lakota orthography is a little + +0:09:41.760,0:09:45.600 +bit more difficult + +0:09:43.040,0:09:46.800 +but still pretty easy i just map a + +0:09:45.600,0:09:49.760 +sequence of keys + +0:09:46.800,0:09:51.760 +a followed by the apostrophe makes the + +0:09:49.760,0:09:53.519 +accented vowels so all of those + +0:09:51.760,0:09:55.839 +and then again we have the hot checks + +0:09:53.519,0:09:58.399 +for the guttural sounds of the language + +0:09:55.839,0:09:59.120 +and the nasal end so that's it basically + +0:09:58.399,0:10:02.480 +these two + +0:09:59.120,0:10:06.560 +definitions allow me to type + +0:10:02.480,0:10:09.279 +lakota language in emacs um + +0:10:06.560,0:10:09.920 +and it's great it works great publishing + +0:10:09.279,0:10:11.760 +it + +0:10:09.920,0:10:13.839 +is another problematic thing i wanted to + +0:10:11.760,0:10:16.079 +use free software to do that + +0:10:13.839,0:10:17.600 +so the first thing i did was i i posted + +0:10:16.079,0:10:19.440 +on sourcehut + +0:10:17.600,0:10:20.959 +which is great it's a good alternative + +0:10:19.440,0:10:22.880 +for a git forge + +0:10:20.959,0:10:24.000 +and i got it published on melba so the + +0:10:22.880,0:10:25.760 +lakota input + +0:10:24.000,0:10:27.760 +package is available if you'd like to + +0:10:25.760,0:10:29.839 +try it out + +0:10:27.760,0:10:31.680 +and bandali one of our hosts for the + +0:10:29.839,0:10:33.200 +conference is helping me now + +0:10:31.680,0:10:35.279 +through the process of committing the + +0:10:33.200,0:10:37.120 +code to emacs + +0:10:35.279,0:10:39.279 +because i would like to do that i would + +0:10:37.120,0:10:41.680 +like it to be available to everyone + +0:10:39.279,0:10:43.279 +through emacs itself so that anyone who + +0:10:41.680,0:10:43.920 +wants to use it just has to download + +0:10:43.279,0:10:46.240 +emacs + +0:10:43.920,0:10:47.120 +and there you go you can type

things + +0:00:32.559,0:00:37.360 +there one is + +0:00:34.320,0:00:39.520 +um emacs is cross platform so + +0:00:37.360,0:00:41.520 +writing this input mode for emacs means + +0:00:39.520,0:00:44.559 +if i do end up using + +0:00:41.520,0:00:46.480 +a non-free operating system i can still + +0:00:44.559,0:00:49.920 +use emacs i can still type + +0:00:46.480,0:00:52.800 +in the way that i would like to um + +0:00:49.920,0:00:54.640 +i did look in i don't i actually don't + +0:00:52.800,0:00:56.719 +know what x compose is + +0:00:54.640,0:00:59.680 +i tried looking for it on my system i + +0:00:56.719,0:01:02.399 +could not find it anywhere + +0:00:59.680,0:01:02.879 +i did actually go and figure out how to + +0:01:02.399,0:01:06.080 +write a + +0:01:02.879,0:01:07.040 +x11 keyboard layout so that's also + +0:01:06.080,0:01:09.840 +available + +0:01:07.040,0:01:11.920 +in the repository that has the emacs + +0:01:09.840,0:01:14.720 +package as well + +0:01:11.920,0:01:15.920 +and it is handy to be able to have that + +0:01:14.720,0:01:20.000 +so i can type in + +0:01:15.920,0:01:20.000 +other applications besides emacs + +0:01:21.200,0:01:25.119 +but the main advantages for emacs was it + +0:01:24.479,0:01:27.439 +was actually + +0:01:25.119,0:01:28.560 +much easier to discover and much easier + +0:01:27.439,0:01:31.439 +to + +0:01:28.560,0:01:33.040 +manipulate and get feedback you know as + +0:01:31.439,0:01:35.360 +i was developing it like i could just + +0:01:33.040,0:01:37.200 +evaluate the coil package + +0:01:35.360,0:01:39.680 +try it out and see if it works when i + +0:01:37.200,0:01:40.560 +was trying to do the x11 inputs i'd have + +0:01:39.680,0:01:42.799 +to log out + +0:01:40.560,0:01:43.759 +read and and relog in again to get + +0:01:42.799,0:01:46.240 +things read and + +0:01:43.759,0:01:46.799 +it was you know it doesn't have that + +0:01:46.240,0:01:50.560 +beautiful + +0:01:46.799,0:01:53.040 +interactivity the way that emacs does so + +0:01:50.560,0:01:54.960 +for me it was a good place to start um + +0:01:53.040,0:01:56.640 +especially because + +0:01:54.960,0:01:58.079 +i had never done anything like this + +0:01:56.640,0:02:00.079 +before like developing + +0:01:58.079,0:02:03.200 +something that felt low level you know + +0:02:00.079,0:02:03.200 +like a keyboard input + +0:02:04.320,0:02:08.479 +i hope that answers your question + +0:02:06.399,0:02:09.280 +question two can you give us a demo of + +0:02:08.479,0:02:12.400 +you typing in + +0:02:09.280,0:02:17.200 +either lakota and input method sure + +0:02:12.400,0:02:17.200 +um share my screen now + +0:02:19.599,0:02:23.840 +of course i always have to select which + +0:02:21.520,0:02:23.840 +one + +0:02:32.239,0:02:37.840 +okay so control backslash opens the + +0:02:36.560,0:02:40.000 +input modes + +0:02:37.840,0:02:41.920 +although when you've selected one you + +0:02:40.000,0:02:45.680 +have it already so + +0:02:41.920,0:02:48.319 +uh yeah wash day + +0:02:45.680,0:02:50.000 +that's it is good washed it so this is + +0:02:48.319,0:02:53.360 +the suggested lakota + +0:02:50.000,0:02:56.560 +orthography or otherwise known as the + +0:02:53.360,0:02:58.800 +standard lakota orthography + +0:02:56.560,0:03:00.640 +another benefit of doing it in emacs is + +0:02:58.800,0:03:05.840 +that i now get + +0:03:00.640,0:03:05.840 +completion on lakota words so + +0:03:06.800,0:03:10.560 +so i'm you know it's a second language + +0:03:08.800,0:03:11.440 +for me and as i'm trying to learn it + +0:03:10.560,0:03:13.760 +it's actually + +0:03:11.440,0:03:15.599 +quite useful to have company mode as a + +0:03:13.760,0:03:19.200 +bonus um + +0:03:15.599,0:03:19.200 +for typing things + +0:03:19.680,0:03:23.599 +i can show the other orthography so to + +0:03:22.239,0:03:27.200 +to get another one you do + +0:03:23.599,0:03:30.560 +the universal input control u backslash + +0:03:27.200,0:03:33.280 +and i can try the white hat orthography + +0:03:30.560,0:03:33.280 +oh yeah lost + +0:03:36.239,0:03:41.440 +what's the command for that you are now + +0:03:39.760,0:03:44.720 +unmuted + +0:03:41.440,0:03:47.840 +yeah okay you are now muted + +0:03:44.720,0:03:47.840 +thank you + +0:03:48.000,0:03:55.680 +you are now unmuted you are now muted + +0:03:52.080,0:03:58.879 +oops not quite as slick as that other + +0:03:55.680,0:04:02.799 +demo we saw the other day + +0:03:58.879,0:04:04.239 +okay so control u control backslash i + +0:04:02.799,0:04:07.200 +can select a different + +0:04:04.239,0:04:10.560 +input method um from the default so if i + +0:04:07.200,0:04:14.480 +select white hat i can type + +0:04:10.560,0:04:18.000 +wash day like that + +0:04:14.480,0:04:19.919 +so it's a different orthography here um + +0:04:18.000,0:04:21.440 +i won't go too deeply into that it's + +0:04:19.919,0:04:23.120 +hard to think and talk and type all at + +0:04:21.440,0:04:26.320 +the same time + +0:04:23.120,0:04:28.560 +um i hope that's good + +0:04:26.320,0:04:31.840 +i'm happy to do more maybe i'll put up a + +0:04:28.560,0:04:35.840 +video of of demonstrating that sometimes + +0:04:31.840,0:04:35.840 +why did i just go ahead + +0:04:36.479,0:04:42.880 +um time about for like one more question + +0:04:39.520,0:04:45.280 +okay on live yeah thank you + +0:04:42.880,0:04:46.240 +um well real quick did i write the + +0:04:45.280,0:04:48.880 +company back end + +0:04:46.240,0:04:50.639 +no that's just the automatic company + +0:04:48.880,0:04:51.280 +completion based on other things i've + +0:04:50.639,0:04:55.440 +typed + +0:04:51.280,0:04:58.080 +why did i decide on the the input method + +0:04:55.440,0:04:58.880 +that's a good question um i just did it + +0:04:58.080,0:05:03.120 +based on + +0:04:58.880,0:05:04.000 +my experience um in the x input mode you + +0:05:03.120,0:05:06.160 +type it first + +0:05:04.000,0:05:07.120 +and honestly i would love any input on + +0:05:06.160,0:05:09.280 +what's more + +0:05:07.120,0:05:10.960 +usual for these type of combining + +0:05:09.280,0:05:13.919 +letters + +0:05:10.960,0:05:15.360 +and really what i would like to do is + +0:05:13.919,0:05:17.600 +kind of confer with other + +0:05:15.360,0:05:19.440 +people from the tribe and talk to elders + +0:05:17.600,0:05:21.440 +and see + +0:05:19.440,0:05:23.600 +what feels right what what is the best + +0:05:21.440,0:05:24.800 +way to go about this + +0:05:23.600,0:05:26.960 +i don't think that it should be an + +0:05:24.800,0:05:27.919 +individual decision and in this case it + +0:05:26.960,0:05:30.880 +is because + +0:05:27.919,0:05:32.320 +i created it for myself but now that + +0:05:30.880,0:05:34.639 +i've released it to the world i think + +0:05:32.320,0:05:37.680 +there's more to think about + +0:05:34.639,0:05:38.800 +okay i guess i have to go now so we can + +0:05:37.680,0:05:42.320 +get to the next talk + +0:05:38.800,0:05:44.320 +thank you for listening okay + +0:05:42.320,0:05:45.759 +thank you very much grant for your + +0:05:44.320,0:05:50.720 +awesome talk and for +

day for writing for translating + +0:00:24.800,0:00:28.160 +for project management + +0:00:26.160,0:00:29.199 +and most importantly for email which + +0:00:28.160,0:00:32.480 +will be the + +0:00:29.199,0:00:35.440 +subject of my talk today so i'm talking + +0:00:32.480,0:00:38.320 +about object-oriented code in emacs + +0:00:35.440,0:00:40.160 +uh most famous possibly oldest + +0:00:38.320,0:00:41.760 +definitely most notorious news reader + +0:00:40.160,0:00:44.320 +slash emacs client + +0:00:41.760,0:00:45.440 +email client so in particular object + +0:00:44.320,0:00:49.520 +oriented code + +0:00:45.440,0:00:49.520 +in news why object-oriented code + +0:00:50.239,0:00:53.600 +the way news works is it started off as + +0:00:51.920,0:00:57.039 +a news reader so for access + +0:00:53.600,0:00:59.120 +accessing nntp servers and later on grew + +0:00:57.039,0:01:01.039 +a whole bunch of new functionality as a + +0:00:59.120,0:01:02.079 +mail client so it can talk to imap + +0:01:01.039,0:01:04.799 +servers + +0:01:02.079,0:01:06.640 +mail dealer directories uh folders on + +0:01:04.799,0:01:08.400 +your file system all kinds of stuff + +0:01:06.640,0:01:09.760 +but it presents a unified interface to + +0:01:08.400,0:01:11.040 +all those things so it's basically + +0:01:09.760,0:01:14.000 +polymorphism + +0:01:11.040,0:01:16.400 +one of the the basic fundamental + +0:01:14.000,0:01:18.720 +principles of object oriented code so + +0:01:16.400,0:01:19.920 +it's a good fit second reason is it + +0:01:18.720,0:01:22.880 +already is + +0:01:19.920,0:01:23.759 +object oriented and i'll get into what + +0:01:22.880,0:01:27.280 +that means + +0:01:23.759,0:01:28.640 +in a second so + +0:01:27.280,0:01:30.640 +the background that you should know is + +0:01:28.640,0:01:32.560 +that most of this code was written in + +0:01:30.640,0:01:34.880 +the 90s + +0:01:32.560,0:01:36.159 +emacs lisp has only grown sort of + +0:01:34.880,0:01:38.640 +official + +0:01:36.159,0:01:41.200 +object orientation support libraries + +0:01:38.640,0:01:43.840 +over the past 10 years or so + +0:01:41.200,0:01:44.799 +from about 2010 to the present so what + +0:01:43.840,0:01:48.640 +does + +0:01:44.799,0:01:50.560 +news do so the basics of + +0:01:48.640,0:01:52.240 +object orientation in most languages are + +0:01:50.560,0:01:53.759 +you you define + +0:01:52.240,0:01:55.840 +a class of some sort and then you + +0:01:53.759,0:01:58.079 +instantiate that class and these + +0:01:55.840,0:02:00.320 +class instances have two things they + +0:01:58.079,0:02:01.759 +have data attributes or + +0:02:00.320,0:02:04.799 +slots or members or whatever you're + +0:02:01.759,0:02:07.280 +going to call them and they have + +0:02:04.799,0:02:08.399 +methods which operate on individual + +0:02:07.280,0:02:11.120 +instances + +0:02:08.399,0:02:12.879 +so you could say that you create or + +0:02:11.120,0:02:13.920 +instantiate an instance of a class in + +0:02:12.879,0:02:16.239 +that instance + +0:02:13.920,0:02:17.120 +owns two things that owns its set of + +0:02:16.239,0:02:20.239 +attributes + +0:02:17.120,0:02:23.280 +and it owns some methods which + +0:02:20.239,0:02:26.720 +also work on the on the instance + +0:02:23.280,0:02:29.040 +so both in nurse's existing code and in + +0:02:26.720,0:02:30.080 +the more standard object oriented emacs + +0:02:29.040,0:02:32.480 +lisp libraries + +0:02:30.080,0:02:34.080 +this relationship is turned on its head + +0:02:32.480,0:02:37.599 +a little bit + +0:02:34.080,0:02:40.239 +in that data slots and + +0:02:37.599,0:02:41.360 +uh and instance methods are defined + +0:02:40.239,0:02:42.959 +outside of the + +0:02:41.360,0:02:45.040 +class or the instances themselves so + +0:02:42.959,0:02:46.879 +they are top level definitions + +0:02:45.040,0:02:48.319 +so we'll get to what that means in the + +0:02:46.879,0:02:49.840 +in the newer libraries um + +0:02:48.319,0:02:51.760 +in a bit but uh first i want to talk + +0:02:49.840,0:02:54.319 +about how news does this and in order to + +0:02:51.760,0:02:57.440 +do that we are going to go deep into + +0:02:54.319,0:02:59.879 +the darkest corner of the new co source + +0:02:57.440,0:03:02.879 +code tree to a library called + +0:02:59.879,0:03:05.040 +nno.l very cryptically + +0:03:02.879,0:03:06.800 +titled uh library and when we open it up + +0:03:05.040,0:03:09.519 +we find + +0:03:06.800,0:03:11.040 +a library with no code comments and + +0:03:09.519,0:03:12.800 +almost no doc strings + +0:03:11.040,0:03:14.159 +almost as if lars was a little ashamed + +0:03:12.800,0:03:16.000 +not ashamed but knew he was doing + +0:03:14.159,0:03:19.040 +something a little bit crazy + +0:03:16.000,0:03:21.040 +and didn't want anyone to see so + +0:03:19.040,0:03:22.400 +this file contains the the object + +0:03:21.040,0:03:24.480 +oriented mechanism + +0:03:22.400,0:03:25.760 +whereby you can define different kinds + +0:03:24.480,0:03:27.280 +of back ends for news + +0:03:25.760,0:03:29.760 +and then those back ends can be + +0:03:27.280,0:03:32.480 +instantiated as individual + +0:03:29.760,0:03:33.360 +servers and as you define these backends + +0:03:32.480,0:03:36.000 +you're supposed to use + +0:03:33.360,0:03:36.640 +two macros which you can see here one is + +0:03:36.000,0:03:39.599 +called def + +0:03:36.640,0:03:41.280 +vu and one is called defu and if you + +0:03:39.599,0:03:43.280 +look at the definitions the definitions + +0:03:41.280,0:03:45.440 +look pretty simple here def vu basically + +0:03:43.280,0:03:49.040 +turns into a def var + +0:03:45.440,0:03:52.239 +and foo turns into a defund + +0:03:49.040,0:03:55.760 +and along with those basic definitions + +0:03:52.239,0:03:58.720 +the library also does some registration + +0:03:55.760,0:04:00.080 +memoization caching of those variables + +0:03:58.720,0:04:01.840 +it saves them in the structure + +0:04:00.080,0:04:03.360 +for later use so that we know that those + +0:04:01.840,0:04:05.280 +are meant to be + +0:04:03.360,0:04:06.640 +uh attributes and methods that are used + +0:04:05.280,0:04:08.000 +with instances + +0:04:06.640,0:04:09.280 +with server instances but you can see + +0:04:08.000,0:04:10.560 +that there's no server instance + +0:04:09.280,0:04:13.200 +definition here there's no + +0:04:10.560,0:04:14.239 +like no nothing these are top level + +0:04:13.200,0:04:18.160 +these are top level + +0:04:14.239,0:04:18.639 +definitions so really data attributes + +0:04:18.160,0:04:22.000 +for + +0:04:18.639,0:04:23.840 +new servers and + +0:04:22.000,0:04:25.440 +methods or functions that operate on + +0:04:23.840,0:04:28.400 +those instances are completely + +0:04:25.440,0:04:29.600 +separate mechanisms they don't really + +0:04:28.400,0:04:31.680 +have anything to do with each other they + +0:04:29.600,0:04:36.560 +don't belong to the same data structures + +0:04:31.680,0:04:36.560 +so how do they work follow me + +0:04:37.120,0:04:41.360 +aka methods and attributes these are all + +0:04:39.520,0:04:44.479 +the things i just said + +0:04:41.360,0:04:47.360 +so when you define a + +0:04:44.479,0:04:47.360 +a backend type + +0:04:48.560,0:04:52.400 +in noose what you get is this a + +0:04:51.199,0:04:54.080 +definition a list + +0:04:52.400,0:04:55.520 +and it'll say there is such a back end + +0:04:54.080,0:04:58.880 +as nnml + +0:04:55.520,0:04:59.520 +and these are its uh data attributes + +0:04:58.880,0:05:01.840 +that any + +0:04:59.520,0:05:02.960 +given instance can have and then these + +0:05:01.840,0:05:04.960 +are + +0:05:02.960,0:05:06.880 +the functions or methods that are + +0:05:04.960,0:05:08.960 +defined to operate on + +0:05:06.880,0:05:11.440 +an instance of this backend so a server + +0:05:08.960,0:05:13.360 +that belongs to the nnml + +0:05:11.440,0:05:15.120 +backend so at least we have this data + +0:05:13.360,0:05:16.880 +here so that's that's handy we don't you + +0:05:15.120,0:05:18.000 +don't really touch that that's like very + +0:05:16.880,0:05:20.560 +very very deep + +0:05:18.000,0:05:22.560 +um use code that doesn't really come up + +0:05:20.560,0:05:25.280 +even as a + +0:05:22.560,0:05:26.479 +even as a bug squasher or whatever we + +0:05:25.280,0:05:27.280 +don't touch that very often but there + +0:05:26.479,0:05:30.400 +they are and that's + +0:05:27.280,0:05:32.080 +that's how they work now the next thing + +0:05:30.400,0:05:34.000 +that obviously you want to know is okay + +0:05:32.080,0:05:35.039 +where are if i've started up news where + +0:05:34.000,0:05:37.199 +are my servers + +0:05:35.039,0:05:39.199 +uh where are these server objects since + +0:05:37.199,0:05:41.840 +this is object oriented + +0:05:39.199,0:05:43.199 +programming and the weird thing that you + +0:05:41.840,0:05:45.199 +will eventually + +0:05:43.199,0:05:46.880 +figure out in some cases after years of + +0:05:45.199,0:05:49.199 +poking around in the new source code + +0:05:46.880,0:05:50.320 +is that servers do not exist in an + +0:05:49.199,0:05:53.440 +ontological + +0:05:50.320,0:05:55.440 +philosophical sense as objects the + +0:05:53.440,0:05:57.039 +primary data structures of noose are + +0:05:55.440,0:05:58.960 +groups + +0:05:57.039,0:06:00.720 +and in sort of an object-oriented + +0:05:58.960,0:06:01.759 +hierarchical you know mindset you'd + +0:06:00.720,0:06:03.759 +think well + +0:06:01.759,0:06:05.759 +groups belong to servers so servers must + +0:06:03.759,0:06:08.000 +exist but they don't + +0:06:05.759,0:06:09.360 +each group and here you can see some + +0:06:08.000,0:06:11.199 +examples of groups + +0:06:09.360,0:06:13.039 +these are basically the data structures + +0:06:11.199,0:06:14.960 +that represent a group each group also + +0:06:13.039,0:06:17.039 +has a little entry here that + +0:06:14.960,0:06:18.000 +that tells you what server it belongs to + +0:06:17.039,0:06:20.479 +and each group + +0:06:18.000,0:06:23.120 +replicates that data uh saying which + +0:06:20.479,0:06:24.479 +server it belongs to and so when + +0:06:23.120,0:06:26.160 +nurse is going through doing its + +0:06:24.479,0:06:27.680 +business uh trying to figure out what's + +0:06:26.160,0:06:29.840 +like updating mail from the groups or + +0:06:27.680,0:06:31.600 +whatever almost every time + +0:06:29.840,0:06:32.960 +it will cycle through all the list of + +0:06:31.600,0:06:34.960 +groups it'll + +0:06:32.960,0:06:36.720 +it'll look at all the server definitions + +0:06:34.960,0:06:38.160 +and it will categorize the groups by + +0:06:36.720,0:06:41.120 +server + +0:06:38.160,0:06:42.160 +which which is just weird because you're + +0:06:41.120,0:06:43.840 +sort of looking for okay where does the + +0:06:42.160,0:06:44.479 +server exist it doesn't exist it's put + +0:06:43.840,0:06:48.319 +together + +0:06:44.479,0:06:50.400 +every time uh out of out of code + +0:06:48.319,0:06:51.840 +elsewhere in the news code base + +0:06:50.400,0:06:54.080 +specifically from these group + +0:06:51.840,0:06:55.199 +these group definitions and so this is + +0:06:54.080,0:06:58.080 +very odd because + +0:06:55.199,0:06:58.720 +in in some sense like here this one its + +0:06:58.080,0:07:02.240 +server is + +0:06:58.720,0:07:03.919 +nnml and an empty string so there's a + +0:07:02.240,0:07:04.479 +certain sense here in which this server + +0:07:03.919,0:07:06.400 +is not + +0:07:04.479,0:07:07.759 +really an object at all what it is is a + +0:07:06.400,0:07:08.560 +set of instructions for how to find + +0:07:07.759,0:07:11.199 +messages + +0:07:08.560,0:07:12.800 +and this set of instructions is go to + +0:07:11.199,0:07:15.440 +the default place where the user + +0:07:12.800,0:07:16.000 +might have their mail and expect to find + +0:07:15.440,0:07:18.080 +messages + +0:07:16.000,0:07:19.840 +there in an nml format which is + +0:07:18.080,0:07:22.479 +basically just one message per + +0:07:19.840,0:07:23.840 +um per file and any number of groups + +0:07:22.479,0:07:25.440 +could have those same instructions uh + +0:07:23.840,0:07:26.720 +but they're not it's not really a thing + +0:07:25.440,0:07:28.639 +it's really just a + +0:07:26.720,0:07:30.240 +it's more of a procedural instruction + +0:07:28.639,0:07:31.919 +and on the other end of the spectrum you + +0:07:30.240,0:07:33.599 +might have an nni map + +0:07:31.919,0:07:35.840 +server which very much is a thing it has + +0:07:33.599,0:07:37.759 +its own it has its own server its own + +0:07:35.840,0:07:40.240 +port its own authentication + +0:07:37.759,0:07:41.360 +system so some of the servers are more + +0:07:40.240,0:07:42.400 +like things some of the servers are more + +0:07:41.360,0:07:45.520 +like instructions + +0:07:42.400,0:07:47.280 +as news works right now um these + +0:07:45.520,0:07:48.879 +most of the servers are treated like + +0:07:47.280,0:07:50.879 +just instruction sets + +0:07:48.879,0:07:53.120 +and and there's no place where you can + +0:07:50.879,0:07:55.360 +go and find them there's no one central + +0:07:53.120,0:07:56.160 +uh variable that defines them all so how + +0:07:55.360,0:07:57.520 +do the + +0:07:56.160,0:07:59.520 +um so we'll talk about the methods in a + +0:07:57.520,0:08:02.639 +second how do the data attributes work + +0:07:59.520,0:08:04.479 +uh put very crudely um + +0:08:02.639,0:08:05.919 +your servers when they're put together + +0:08:04.479,0:08:08.080 +uh they are okay they are + +0:08:05.919,0:08:08.960 +kept in a variable and it's called nno + +0:08:08.080,0:08:11.120 +nno + +0:08:08.960,0:08:12.960 +state a list and there's a concept to + +0:08:11.120,0:08:16.560 +this of the current server + +0:08:12.960,0:08:19.039 +so when we go here let's go back to + +0:08:16.560,0:08:20.560 +our nnno definition a list so when we + +0:08:19.039,0:08:22.240 +have an nnml + +0:08:20.560,0:08:24.400 +server say we have one here and it's + +0:08:22.240,0:08:26.639 +just this blank string + +0:08:24.400,0:08:28.879 +these are all when you define that in + +0:08:26.639,0:08:31.919 +your own uh server definition code + +0:08:28.879,0:08:32.399 +you can put in different values for all + +0:08:31.919,0:08:35.760 +of these + +0:08:32.399,0:08:37.039 +various attributes and when noose comes + +0:08:35.760,0:08:38.959 +when it comes time for news to operate + +0:08:37.039,0:08:40.640 +on this server in particular ask it to + +0:08:38.959,0:08:42.080 +you know open a group or get new mail + +0:08:40.640,0:08:45.360 +what it will do is it will take + +0:08:42.080,0:08:45.920 +that particular server's data from these + +0:08:45.360,0:08:47.600 +symbols + +0:08:45.920,0:08:49.600 +and it will copy all that information + +0:08:47.600,0:08:51.760 +into the global devfars + +0:08:49.600,0:08:53.120 +so for the time that you are operating + +0:08:51.760,0:08:55.920 +on this particular server + +0:08:53.120,0:08:56.800 +its individual data becomes the values + +0:08:55.920,0:08:59.360 +of these global + +0:08:56.800,0:09:00.560 +variables which when you realize what's + +0:08:59.360,0:09:02.080 +happening is sort of terrifying you + +0:09:00.560,0:09:04.480 +think oh my god + +0:09:02.080,0:09:05.760 +but at the same time it's actually kind + +0:09:04.480,0:09:07.279 +of impressive and it's amazing that it + +0:09:05.760,0:09:09.120 +works as well as it does + +0:09:07.279,0:09:10.880 +i'm actually a little bit in awe of the + +0:09:09.120,0:09:12.560 +of the code in this in this library i + +0:09:10.880,0:09:15.760 +think it's pretty impressive + +0:09:12.560,0:09:18.320 +so as you nno change server + +0:09:15.760,0:09:20.080 +uh this function here these values get + +0:09:18.320,0:09:21.440 +copied into the global value into the + +0:09:20.080,0:09:22.399 +global variables and then as you go on + +0:09:21.440,0:09:24.000 +the next server + +0:09:22.399,0:09:26.399 +that gets you know cleaned out and + +0:09:24.000,0:09:29.680 +recopied there are a few + +0:09:26.399,0:09:32.000 +um a few other slot types + +0:09:29.680,0:09:33.440 +or attribute types which do because all + +0:09:32.000,0:09:34.720 +of these attributes see they all start + +0:09:33.440,0:09:37.920 +with the nml + +0:09:34.720,0:09:40.560 +or in this case and in folder prefix + +0:09:37.920,0:09:41.760 +but there are a few slot types that all + +0:09:40.560,0:09:43.279 +servers need for + +0:09:41.760,0:09:45.920 +for instance their most recent status + +0:09:43.279,0:09:46.640 +message a status symbol like open denied + +0:09:45.920,0:09:48.080 +whatever + +0:09:46.640,0:09:49.680 +and that data is sort of scattered + +0:09:48.080,0:09:51.200 +around the rest of the news + +0:09:49.680,0:09:53.440 +code base in various variables or + +0:09:51.200,0:09:55.440 +various places + +0:09:53.440,0:09:56.560 +so that's that sort of just contributes + +0:09:55.440,0:09:57.360 +to the confusion when you're trying to + +0:09:56.560,0:10:00.720 +figure out why + +0:09:57.360,0:10:03.839 +things are going wrong so that is our + +0:10:00.720,0:10:05.440 +um nnoo which is and + +0:10:03.839,0:10:07.360 +sort of how the attributes and these + +0:10:05.440,0:10:09.120 +global variables work + +0:10:07.360,0:10:10.480 +if we want to talk about defu and the + +0:10:09.120,0:10:19.839 +methods we + +0:10:10.480,0:10:19.839 +go to + +0:10:20.800,0:10:25.600 +and so this is the place where all the + +0:10:23.200,0:10:27.200 +server level methods are defined + +0:10:25.600,0:10:29.279 +and what we have here are things like + +0:10:27.200,0:10:32.640 +here's an example there's closed server + +0:10:29.279,0:10:36.320 +this closed server is given a + +0:10:32.640,0:10:38.079 +a server as a an argument + +0:10:36.320,0:10:40.560 +it looks at the server and basically it + +0:10:38.079,0:10:42.079 +finds the proper function to call on + +0:10:40.560,0:10:45.120 +this particular server + +0:10:42.079,0:10:45.600 +using the function new skip function by + +0:10:45.120,0:10:48.959 +taking + +0:10:45.600,0:10:49.760 +the sort of latter half of this function + +0:10:48.959,0:10:52.079 +symbol + +0:10:49.760,0:10:53.440 +and pasting it together with the symbol + +0:10:52.079,0:10:56.800 +that represents the back end so + +0:10:53.440,0:10:59.600 +if you were calling this on an nni map + +0:10:56.800,0:11:01.279 +server your skip function would look at + +0:10:59.600,0:11:02.240 +your imap server look at closed server i + +0:11:01.279,0:11:05.120 +knew what + +0:11:02.240,0:11:05.120 +it would come up with + +0:11:07.839,0:11:11.920 +server sure enough there's an imac close + +0:11:10.240,0:11:12.240 +server and it'll call this code and then + +0:11:11.920,0:11:14.000 +it'll + +0:11:12.240,0:11:15.279 +it'll go and do its other bookkeeping + +0:11:14.000,0:11:18.320 +another sort of + +0:11:15.279,0:11:19.279 +surrounding code and so that's not that + +0:11:18.320,0:11:22.640 +actually works pretty well + +0:11:19.279,0:11:24.959 +uh as as things go uh defu + +0:11:22.640,0:11:26.800 +makes a record that this this function + +0:11:24.959,0:11:28.320 +exists and nus gets function get + +0:11:26.800,0:11:29.600 +function looks on that cache finds the + +0:11:28.320,0:11:30.959 +function and calls it + +0:11:29.600,0:11:32.560 +now what's particularly confusing is + +0:11:30.959,0:11:33.360 +that you don't actually even have to use + +0:11:32.560,0:11:35.519 +defu + +0:11:33.360,0:11:38.399 +so whoever wrote and then mail gear + +0:11:35.519,0:11:39.920 +which is a weird library + +0:11:38.399,0:11:41.600 +said to heck with you i'm not using any + +0:11:39.920,0:11:43.120 +of these + +0:11:41.600,0:11:45.839 +any of this machinery i'm going to do it + +0:11:43.120,0:11:49.680 +myself so we have + +0:11:45.839,0:11:52.320 +def structs to hold uh the instance + +0:11:49.680,0:11:53.040 +data and then we have just plain old + +0:11:52.320,0:11:55.680 +defense + +0:11:53.040,0:11:57.279 +for things like animal your close server + +0:11:55.680,0:11:59.279 +request close all of these + +0:11:57.279,0:12:00.320 +these server level uh variables and it + +0:11:59.279,0:12:03.360 +just turns out that + +0:12:00.320,0:12:05.839 +news in its belt and suspenders + +0:12:03.360,0:12:07.279 +approach to uh to coding it'll actually + +0:12:05.839,0:12:10.320 +just go out if it can't find + +0:12:07.279,0:12:12.160 +the memoized function it'll just go out + +0:12:10.320,0:12:14.240 +and say has anybody defined a function + +0:12:12.160,0:12:16.000 +that looks like this pattern and then + +0:12:14.240,0:12:17.920 +and then melder says yes i did and then + +0:12:16.000,0:12:19.920 +we call it and then we go so it's just + +0:12:17.920,0:12:21.440 +it's fine it works it just adds to the + +0:12:19.920,0:12:24.240 +confusion why + +0:12:21.440,0:12:25.440 +why does it work we don't know sometimes + +0:12:24.240,0:12:26.880 +the only thing worse than not knowing + +0:12:25.440,0:12:30.000 +why something doesn't work is + +0:12:26.880,0:12:30.560 +not knowing why something does work um + +0:12:30.000,0:12:31.920 +and then + +0:12:30.560,0:12:33.680 +a last little bit i want to touch on + +0:12:31.920,0:12:35.440 +here is inheritance which is another + +0:12:33.680,0:12:38.480 +sort of cornerstone of object-oriented + +0:12:35.440,0:12:40.160 +coding as far as i can tell only uh + +0:12:38.480,0:12:41.920 +the only inheritance that goes on is in + +0:12:40.160,0:12:45.519 +something called nn male + +0:12:41.920,0:12:48.399 +which provides sort of common functions + +0:12:45.519,0:12:49.360 +for back ends that keep their mail on + +0:12:48.399,0:12:52.000 +your + +0:12:49.360,0:12:53.680 +local machine and you can spool it you + +0:12:52.000,0:12:55.440 +can delete it you can you know you own + +0:12:53.680,0:12:56.160 +the messages it's not like an nntp + +0:12:55.440,0:12:59.040 +server + +0:12:56.160,0:13:00.160 +and so a lot of those male deer nnml + +0:12:59.040,0:13:02.959 +whatever + +0:13:00.160,0:13:04.079 +a lot of those have sort of similar code + +0:13:02.959,0:13:07.600 +which they + +0:13:04.079,0:13:09.600 +which they share via this nn mail + +0:13:07.600,0:13:12.959 +you call it an abstract parent class i + +0:13:09.600,0:13:15.440 +guess so if you have something like nnml + +0:13:12.959,0:13:16.720 +it has a request scan uh when it goes + +0:13:15.440,0:13:18.800 +into request scan + +0:13:16.720,0:13:21.760 +it ends up calling nnmail.newmail and it + +0:13:18.800,0:13:23.279 +says i am calling this as an nml server + +0:13:21.760,0:13:24.959 +and here are some of my callback + +0:13:23.279,0:13:26.000 +functions and my variables that i would + +0:13:24.959,0:13:28.000 +like you to use + +0:13:26.000,0:13:30.120 +when you are getting your email so in + +0:13:28.000,0:13:33.120 +this way the code is sort of you know + +0:13:30.120,0:13:35.680 +inter-interleaved between the the child + +0:13:33.120,0:13:37.120 +class and the parent class even though + +0:13:35.680,0:13:39.440 +we're not talking in terms of classes + +0:13:37.120,0:13:42.160 +here at all really + +0:13:39.440,0:13:42.959 +so that's how noose works right now i + +0:13:42.160,0:13:45.519 +hope that's clear + +0:13:42.959,0:13:46.560 +it certainly wasn't to me and i still + +0:13:45.519,0:13:48.079 +have to go refresh my + +0:13:46.560,0:13:50.079 +memory i'd like to talk a little bit + +0:13:48.079,0:13:51.600 +about sort of the newer + +0:13:50.079,0:13:54.240 +libraries that are available now for + +0:13:51.600,0:13:56.959 +doing object-oriented code + +0:13:54.240,0:13:59.279 +uh as i mentioned i think earlier nno + +0:13:56.959,0:14:00.320 +the copyright headers for 1996 so that's + +0:13:59.279,0:14:02.639 +pretty venerable + +0:14:00.320,0:14:05.519 +coincidentally around the same time eric + +0:14:02.639,0:14:08.320 +ludlum started developing e-i-e-i-o + +0:14:05.519,0:14:09.360 +which is a which is sort of inspired by + +0:14:08.320,0:14:12.720 +a common lisp's + +0:14:09.360,0:14:14.240 +common lisp object system um i got a + +0:14:12.720,0:14:14.959 +very good introduction to that from this + +0:14:14.240,0:14:16.399 +book + +0:14:14.959,0:14:18.000 +practical common lisp which i would + +0:14:16.399,0:14:20.079 +encourage you to look at if you haven't + +0:14:18.000,0:14:22.320 +which you probably have anyway + +0:14:20.079,0:14:23.920 +e-i-e-i-o was incorporated into emacs in + +0:14:22.320,0:14:27.839 +2010 + +0:14:23.920,0:14:30.240 +so that yeah e-i-e-i-o provides um + +0:14:27.839,0:14:32.079 +the deaf class statements it provides + +0:14:30.240,0:14:32.639 +deaf generics deaf methods all that sort + +0:14:32.079,0:14:34.800 +of stuff + +0:14:32.639,0:14:36.320 +sort of a common lisp object-oriented + +0:14:34.800,0:14:38.399 +code + +0:14:36.320,0:14:39.760 +at some point stephan monier's money + +0:14:38.399,0:14:41.199 +money another name i haven't pronounced + +0:14:39.760,0:14:43.839 +it all out + +0:14:41.199,0:14:45.120 +started either cleaning up that code or + +0:14:43.839,0:14:46.959 +for one reason or another writing a + +0:14:45.120,0:14:48.000 +re-implementation of generic functions + +0:14:46.959,0:14:51.440 +which was added + +0:14:48.000,0:14:51.920 +uh in 2015 and then throughout this time + +0:14:51.440,0:14:54.639 +another + +0:14:51.920,0:14:55.760 +sort of object-oriented style + +0:14:54.639,0:14:58.160 +declaration is + +0:14:55.760,0:15:00.000 +defstruct which started off in the cl + +0:14:58.160,0:15:01.600 +libraries + +0:15:00.000,0:15:02.959 +implemented with vectors later was + +0:15:01.600,0:15:04.639 +implemented with records so they're + +0:15:02.959,0:15:06.720 +easier to target + +0:15:04.639,0:15:08.399 +anyway that's another option so how + +0:15:06.720,0:15:09.279 +would we this is i'm probably out of + +0:15:08.399,0:15:13.040 +time already but + +0:15:09.279,0:15:13.040 +we're only getting to the part + +0:15:13.839,0:15:17.920 +the whole point of this is how would we + +0:15:15.760,0:15:19.920 +rewrite someone news's code to use these + +0:15:17.920,0:15:21.760 +newer libraries + +0:15:19.920,0:15:23.839 +if we didn't have to support third party + +0:15:21.760,0:15:26.639 +libraries this wouldn't be that hard + +0:15:23.839,0:15:28.160 +but out there noose is really up on uh + +0:15:26.639,0:15:30.240 +you know backwards compatibility and not + +0:15:28.160,0:15:33.040 +breaking people's stuff and you know + +0:15:30.240,0:15:34.240 +multi-decade support for things so there + +0:15:33.040,0:15:35.759 +are people out there who have written + +0:15:34.240,0:15:38.480 +third-party libraries + +0:15:35.759,0:15:40.000 +um defining new backends for you can use + +0:15:38.480,0:15:41.759 +like hacker news or whatever as + +0:15:40.000,0:15:43.199 +a as a server so we want to be able to + +0:15:41.759,0:15:44.240 +support those if you didn't have to + +0:15:43.199,0:15:46.079 +support those it'd be fine you'd + +0:15:44.240,0:15:47.440 +re-implement you'd use generic functions + +0:15:46.079,0:15:48.560 +you'd use either structure classes + +0:15:47.440,0:15:51.040 +whatever but we got a + +0:15:48.560,0:15:52.000 +it's a little bit tricky to support + +0:15:51.040,0:15:54.320 +these other people's + +0:15:52.000,0:15:56.079 +libraries so one of the things we can do + +0:15:54.320,0:15:59.279 +is rewrite the defu + +0:15:56.079,0:16:00.079 +so if you remember defu is the thing + +0:15:59.279,0:16:03.120 +that uh + +0:16:00.079,0:16:04.800 +or sorry uh defu + +0:16:03.120,0:16:07.040 +is the thing that defines methods that + +0:16:04.800,0:16:10.160 +operate on object answers + +0:16:07.040,0:16:10.639 +instances and we can uh rewrite that to + +0:16:10.160,0:16:13.440 +use + +0:16:10.639,0:16:14.240 +cldef generic and that's this is fairly + +0:16:13.440,0:16:15.440 +fairly simple + +0:16:14.240,0:16:17.759 +it looks like a lot of code it's not a + +0:16:15.440,0:16:20.320 +lot of good for instance we have the + +0:16:17.759,0:16:21.199 +new closed server code that we looked at + +0:16:20.320,0:16:22.720 +earlier + +0:16:21.199,0:16:24.560 +and we have this phone call and the new + +0:16:22.720,0:16:28.720 +skip function so this would look + +0:16:24.560,0:16:30.240 +like using generic functions and methods + +0:16:28.720,0:16:32.959 +it would look like this we'd have + +0:16:30.240,0:16:34.560 +a generic def generic which is just a + +0:16:32.959,0:16:36.320 +sort of a declaration + +0:16:34.560,0:16:37.680 +and a doc string and then we have those + +0:16:36.320,0:16:40.320 +implementations + +0:16:37.680,0:16:42.399 +so we can see what the original code + +0:16:40.320,0:16:44.720 +does here is it first says okay what + +0:16:42.399,0:16:45.839 +type is our our is our argument here and + +0:16:44.720,0:16:48.560 +if it's a string + +0:16:45.839,0:16:50.160 +then go and get the proper s the proper + +0:16:48.560,0:16:52.480 +method definition + +0:16:50.160,0:16:53.920 +from that string so the way we do that + +0:16:52.480,0:16:56.000 +with methods is we + +0:16:53.920,0:16:57.440 +we say if the server is a string so if + +0:16:56.000,0:16:58.720 +it matches this type + +0:16:57.440,0:17:00.320 +then what we're going to do is just + +0:16:58.720,0:17:02.160 +recall we're going to call this function + +0:17:00.320,0:17:05.199 +all over again + +0:17:02.160,0:17:06.400 +using uh basically the same code here + +0:17:05.199,0:17:07.600 +the same code that takes a string and + +0:17:06.400,0:17:10.640 +gets the object so + +0:17:07.600,0:17:11.600 +this does this can add extra function + +0:17:10.640,0:17:12.880 +calls + +0:17:11.600,0:17:14.880 +depending on how you've written the rest + +0:17:12.880,0:17:16.640 +of your code um but this is sort of the + +0:17:14.880,0:17:19.679 +canonical way of doing this + +0:17:16.640,0:17:20.559 +uh using methods then our next part here + +0:17:19.679,0:17:22.000 +is + +0:17:20.559,0:17:24.559 +nishkit function we're going to get a + +0:17:22.000,0:17:26.079 +function called closed server + +0:17:24.559,0:17:27.360 +the difference here is that all these + +0:17:26.079,0:17:28.000 +functions are all going to be called + +0:17:27.360,0:17:29.360 +close + +0:17:28.000,0:17:31.120 +news close server they're not going to + +0:17:29.360,0:17:32.799 +be called news like nni my + +0:17:31.120,0:17:34.400 +closed server and ntp close server + +0:17:32.799,0:17:36.160 +they're all going to have the same name + +0:17:34.400,0:17:37.440 +and what we do is uh we have an around + +0:17:36.160,0:17:40.640 +method + +0:17:37.440,0:17:43.679 +for any server that is a const which is + +0:17:40.640,0:17:45.520 +which is as close as we care to get uh + +0:17:43.679,0:17:46.799 +for you know zeroing in on the type that + +0:17:45.520,0:17:48.559 +we're looking for + +0:17:46.799,0:17:50.480 +we put in a round method on that so that + +0:17:48.559,0:17:51.679 +we can call the next method which we'll + +0:17:50.480,0:17:53.440 +call the more specific + +0:17:51.679,0:17:55.600 +method and then we have our other + +0:17:53.440,0:17:57.280 +bookkeeping code to clean up you know + +0:17:55.600,0:17:58.640 +set up tear down code we'll go around + +0:17:57.280,0:18:00.080 +that + +0:17:58.640,0:18:02.080 +and then in one of the back-end + +0:18:00.080,0:18:04.320 +definitions for instance in an imap + +0:18:02.080,0:18:05.760 +we have another news closed server thing + +0:18:04.320,0:18:08.880 +this looks at the server + +0:18:05.760,0:18:10.799 +and it says is this server a list that + +0:18:08.880,0:18:12.480 +starts with a symbol and an imap and if + +0:18:10.799,0:18:13.679 +it is then we're almost guaranteed that + +0:18:12.480,0:18:15.840 +this is what we wanted + +0:18:13.679,0:18:17.600 +and then this is where we would insert + +0:18:15.840,0:18:18.960 +all the rest of the code from anonymous + +0:18:17.600,0:18:20.799 +closed server + +0:18:18.960,0:18:22.880 +where we'd re-redefine that to look like + +0:18:20.799,0:18:26.080 +this so it's not that hard + +0:18:22.880,0:18:28.720 +theoretically so what we would do + +0:18:26.080,0:18:29.679 +is take the defu macro macro and then + +0:18:28.720,0:18:32.240 +rewrite that + +0:18:29.679,0:18:33.039 +so that it actually defines a cl def + +0:18:32.240,0:18:35.520 +method like + +0:18:33.039,0:18:36.320 +one of these now there's a couple of + +0:18:35.520,0:18:38.960 +these things + +0:18:36.320,0:18:41.200 +unfortunately it's not that easy get rid + +0:18:38.960,0:18:43.490 +of you + +0:18:41.200,0:18:46.400 +a couple of these things + +0:18:43.490,0:18:49.039 +[Music] + +0:18:46.400,0:18:49.919 +that don't use their server as the first + +0:18:49.039,0:18:52.400 +argument + +0:18:49.919,0:18:53.280 +or any of the arguments or it's an + +0:18:52.400,0:18:54.720 +optional argument + +0:18:53.280,0:18:56.640 +and we need the server to be in there to + +0:18:54.720,0:18:58.799 +dispatch on its type + +0:18:56.640,0:19:00.080 +if the server doesn't show up as a as a + +0:18:58.799,0:19:01.760 +required + +0:19:00.080,0:19:03.600 +argument we're not going to be able to + +0:19:01.760,0:19:07.440 +locate the the proper + +0:19:03.600,0:19:10.640 +function call so in the case of + +0:19:07.440,0:19:12.080 +noose request group here we start with + +0:19:10.640,0:19:12.720 +the group it's the group that matters + +0:19:12.080,0:19:14.960 +and we get + +0:19:12.720,0:19:16.240 +the newscommand method as an optional + +0:19:14.960,0:19:18.559 +argument + +0:19:16.240,0:19:20.480 +so that's not cool we don't want that so + +0:19:18.559,0:19:21.360 +what we need instead is something that + +0:19:20.480,0:19:23.840 +looks like this + +0:19:21.360,0:19:25.360 +what we're going to do with uh this is + +0:19:23.840,0:19:26.640 +gonna be just terrible terrible code but + +0:19:25.360,0:19:28.160 +hopefully it won't get used very often + +0:19:26.640,0:19:30.559 +it's gonna be really embarrassing + +0:19:28.160,0:19:31.520 +um defu what's what definitely was gonna + +0:19:30.559,0:19:33.200 +have to do is + +0:19:31.520,0:19:34.559 +say okay is this a function that doesn't + +0:19:33.200,0:19:35.360 +have the server as the first argument + +0:19:34.559,0:19:36.960 +and if it does + +0:19:35.360,0:19:38.400 +it's gonna say oh it's news request + +0:19:36.960,0:19:39.280 +group what happens has to happen with + +0:19:38.400,0:19:40.799 +news request group + +0:19:39.280,0:19:43.200 +is we take the news command method and + +0:19:40.799,0:19:46.240 +we're going to move it up to the front + +0:19:43.200,0:19:47.520 +to the first argument here and it's + +0:19:46.240,0:19:48.720 +either going to be + +0:19:47.520,0:19:50.840 +it's either going to be given or it's + +0:19:48.720,0:19:52.080 +going to be nil because it's it is + +0:19:50.840,0:19:54.320 +optional + +0:19:52.080,0:19:55.760 +okay i briefly edited the space time + +0:19:54.320,0:19:56.400 +continuum there to conceal the fact that + +0:19:55.760,0:19:57.679 +i had + +0:19:56.400,0:19:59.440 +actually not finished writing the code + +0:19:57.679,0:20:02.159 +that i was supposed to write anyway + +0:19:59.440,0:20:02.960 +um so now we have once we've reordered + +0:20:02.159,0:20:04.320 +the + +0:20:02.960,0:20:05.760 +the arguments to the function then we + +0:20:04.320,0:20:06.880 +have to check our various possible + +0:20:05.760,0:20:08.640 +values one is + +0:20:06.880,0:20:10.080 +uh that the server was not passed in in + +0:20:08.640,0:20:12.400 +which case we recall + +0:20:10.080,0:20:13.840 +request group with the server um the + +0:20:12.400,0:20:15.360 +other is that it's just a string in + +0:20:13.840,0:20:16.559 +which case we do that and then this is + +0:20:15.360,0:20:18.559 +sort of the the normal + +0:20:16.559,0:20:20.720 +the normal case that we would expect to + +0:20:18.559,0:20:21.039 +cons so that's not that bad it's not you + +0:20:20.720,0:20:23.760 +know + +0:20:21.039,0:20:24.480 +it's not beautiful um i would be sort of + +0:20:23.760,0:20:26.159 +ashamed to + +0:20:24.480,0:20:28.000 +let anybody see that particular macro + +0:20:26.159,0:20:30.640 +but i think that it would work okay + +0:20:28.000,0:20:31.440 +now the more difficult thing is going to + +0:20:30.640,0:20:34.640 +be + +0:20:31.440,0:20:37.600 +the data variables so + +0:20:34.640,0:20:39.360 +the equivalent of def vu because our two + +0:20:37.600,0:20:41.039 +options for defining classes here are + +0:20:39.360,0:20:41.919 +def struct and def class both of which + +0:20:41.039,0:20:45.280 +required you + +0:20:41.919,0:20:46.960 +to define the slots inside this macro + +0:20:45.280,0:20:49.039 +itself + +0:20:46.960,0:20:51.280 +so defu is top level um how do we get + +0:20:49.039,0:20:55.039 +the top level this top level macro + +0:20:51.280,0:20:56.240 +uh to insert slot names into these + +0:20:55.039,0:20:58.960 +definitions it's + +0:20:56.240,0:21:00.240 +it's possible that it'll be um that i + +0:20:58.960,0:21:03.039 +could monkey patch + +0:21:00.240,0:21:04.799 +uh an existing struct or an existing + +0:21:03.039,0:21:05.280 +class to add a new slot into it that + +0:21:04.799,0:21:07.760 +sounds + +0:21:05.280,0:21:09.600 +ugly the other option would be to give + +0:21:07.760,0:21:11.520 +it a server variable slot which is just + +0:21:09.600,0:21:13.760 +a generalized bucket + +0:21:11.520,0:21:15.520 +that holds anything that gets defined + +0:21:13.760,0:21:16.720 +via def loop + +0:21:15.520,0:21:18.799 +i don't like either of those solutions + +0:21:16.720,0:21:22.480 +but i'm i don't see any other + +0:21:18.799,0:21:25.520 +any other way of doing that so we re + +0:21:22.480,0:21:27.440 +rewrite the nno declare macro to either + +0:21:25.520,0:21:29.840 +be a destructor or a def class + +0:21:27.440,0:21:31.039 +and we rewrite the def boom macro to + +0:21:29.840,0:21:33.039 +somehow + +0:21:31.039,0:21:34.480 +associate that variable name the symbol + +0:21:33.039,0:21:36.159 +with the with the resulting class + +0:21:34.480,0:21:37.760 +definition + +0:21:36.159,0:21:39.600 +then the last question is do we use + +0:21:37.760,0:21:41.600 +structure classes + +0:21:39.600,0:21:43.200 +they both got their their strengths and + +0:21:41.600,0:21:46.480 +their weaknesses + +0:21:43.200,0:21:47.520 +the nice thing is that i mean i've got + +0:21:46.480,0:21:49.600 +how many servers you're going to have + +0:21:47.520,0:21:51.919 +really i've got i think less than 10 + +0:21:49.600,0:21:52.960 +uh truly deranged mine might have as as + +0:21:51.919,0:21:55.440 +many as + +0:21:52.960,0:21:56.480 +50 let's double that to 100 100 of + +0:21:55.440,0:21:58.400 +anything is not going to matter it + +0:21:56.480,0:22:00.159 +doesn't matter what we use + +0:21:58.400,0:22:02.720 +death structures are simpler they're + +0:22:00.159,0:22:05.600 +lighter weight they're defined on top of + +0:22:02.720,0:22:06.960 +the direct the c records so you know + +0:22:05.600,0:22:08.559 +that's nice + +0:22:06.960,0:22:10.320 +the slots don't carry very much + +0:22:08.559,0:22:11.760 +information with them there's no type + +0:22:10.320,0:22:14.480 +information there's no doc string for + +0:22:11.760,0:22:16.559 +the slots themselves + +0:22:14.480,0:22:17.919 +they can also only do single inheritance + +0:22:16.559,0:22:21.120 +which some might say + +0:22:17.919,0:22:22.640 +was an advantage def class each slot + +0:22:21.120,0:22:24.000 +gets a lot more information associated + +0:22:22.640,0:22:24.480 +with it with it which i think can be + +0:22:24.000,0:22:27.120 +nice + +0:22:24.480,0:22:28.799 +it can do multiple inheritance if you're + +0:22:27.120,0:22:30.720 +going to go there + +0:22:28.799,0:22:32.640 +they are heavier weight in particular + +0:22:30.720,0:22:34.080 +their printed representation is gross + +0:22:32.640,0:22:35.840 +it's enormous + +0:22:34.080,0:22:37.520 +so if you see one show up in a back + +0:22:35.840,0:22:38.240 +trace or in your messages buffer can + +0:22:37.520,0:22:39.520 +really + +0:22:38.240,0:22:41.360 +it can really blow that up and make it + +0:22:39.520,0:22:43.200 +hard to read this of course won't be an + +0:22:41.360,0:22:46.240 +issue because our code won't have any + +0:22:43.200,0:22:48.320 +errors in it um my argument for multiple + +0:22:46.240,0:22:51.280 +inheritance here is that i can imagine + +0:22:48.320,0:22:52.720 +new servers falling into sort of like a + +0:22:51.280,0:22:56.240 +little two by two matrix of + +0:22:52.720,0:22:56.799 +of parent classes one being news versus + +0:22:56.240,0:23:00.320 +mail + +0:22:56.799,0:23:00.720 +so news the messages belong to somebody + +0:23:00.320,0:23:02.080 +else + +0:23:00.720,0:23:03.840 +you can't touch them you can't delete + +0:23:02.080,0:23:06.000 +them mail meaning + +0:23:03.840,0:23:08.960 +the messages are under your command + +0:23:06.000,0:23:11.039 +either a local mail dealer a remote imap + +0:23:08.960,0:23:12.640 +you're allowed to spool them copy them + +0:23:11.039,0:23:13.919 +delete them at will + +0:23:12.640,0:23:16.400 +and then the other sort of line of the + +0:23:13.919,0:23:19.760 +matrix would be a local file system + +0:23:16.400,0:23:20.559 +versus some kind of a you know server + +0:23:19.760,0:23:23.280 +port + +0:23:20.559,0:23:24.960 +remote access and that second the server + +0:23:23.280,0:23:26.880 +port remote access thing might require + +0:23:24.960,0:23:28.559 +authentication it might require a keep + +0:23:26.880,0:23:30.159 +alive for a connection + +0:23:28.559,0:23:31.600 +um it's there's going to be a process + +0:23:30.159,0:23:32.400 +there rather than just file system + +0:23:31.600,0:23:33.840 +commands + +0:23:32.400,0:23:35.360 +so i could see if i was going to do + +0:23:33.840,0:23:36.240 +multiple inheritance that's what i would + +0:23:35.360,0:23:39.039 +do those two + +0:23:36.240,0:23:40.400 +those two possible parent classes anyway + +0:23:39.039,0:23:41.520 +that's as far as i've gotten + +0:23:40.400,0:23:43.279 +i thought that i would be able to write + +0:23:41.520,0:23:44.720 +more of this code before i did this talk + +0:23:43.279,0:23:46.720 +but instead i spent the whole time + +0:23:44.720,0:23:48.320 +messing with video codecs but that's + +0:23:46.720,0:23:49.440 +where we're at and i'm going to cut + +0:23:48.320,0:23:50.960 +myself off now + +0:23:49.440,0:23:53.440 +i hope there are questions i hope i'm + +0:23:50.960,0:23:55.919 +there to to answer your questions + +0:23:53.440,0:23:57.120 +and

+0:00:14.480,0:00:18.400 +so um hello everyone my name is ferming + +0:00:17.199,0:00:20.960 +i'm a programmer + +0:00:18.400,0:00:22.400 +a math student from spain i've been + +0:00:20.960,0:00:24.960 +using me e-max for + +0:00:22.400,0:00:26.000 +two years now more or less and today i'm + +0:00:24.960,0:00:28.320 +going to talk about + +0:00:26.000,0:00:29.199 +a maxima computer algebra system in 2 + +0:00:28.320,0:00:32.239 +max + +0:00:29.199,0:00:34.239 +so let's talk about what is maxima + +0:00:32.239,0:00:36.079 +well maxim is a system for manipulation + +0:00:34.239,0:00:37.920 +of symbolic and numerical expression + +0:00:36.079,0:00:39.440 +and it's similar in some regard to + +0:00:37.920,0:00:42.160 +octave + +0:00:39.440,0:00:45.039 +and it's also free software is derived + +0:00:42.160,0:00:47.120 +from the maxima from the 60 from the m80 + +0:00:45.039,0:00:48.320 +and it's written in common lisp which is + +0:00:47.120,0:00:50.719 +a language that i really + +0:00:48.320,0:00:51.600 +like i enjoy writing it so for me it's a + +0:00:50.719,0:00:55.039 +plus + +0:00:51.600,0:00:57.039 +okay so let's talk about the initial + +0:00:55.039,0:00:59.280 +support for maxima when i first started + +0:00:57.039,0:01:00.320 +using it i looked for support into emacs + +0:00:59.280,0:01:03.120 +and i found that + +0:01:00.320,0:01:04.640 +there's two major modes in the main + +0:01:03.120,0:01:07.200 +repository of maxima + +0:01:04.640,0:01:09.280 +for remax the first one is imaxima which + +0:01:07.200,0:01:12.000 +i don't know too much about it + +0:01:09.280,0:01:13.439 +and the second one is maxima dot l which + +0:01:12.000,0:01:16.640 +is the one i took first + +0:01:13.439,0:01:18.080 +and it was pretty nice has like a major + +0:01:16.640,0:01:21.280 +mode a minor mode + +0:01:18.080,0:01:23.040 +a nice ripple but it also has some + +0:01:21.280,0:01:25.040 +disadvantage + +0:01:23.040,0:01:26.479 +and the first one is that is quite + +0:01:25.040,0:01:29.600 +outdated i think + +0:01:26.479,0:01:30.960 +it was from the 2007 + +0:01:29.600,0:01:33.280 +so it's not tested with the current + +0:01:30.960,0:01:35.520 +email version and the second one + +0:01:33.280,0:01:36.320 +is that it doesn't use modern e-max + +0:01:35.520,0:01:38.640 +capability + +0:01:36.320,0:01:40.479 +i'm talking for example about the last + +0:01:38.640,0:01:44.720 +or more latex preview + +0:01:40.479,0:01:46.079 +from the last a max 27.1 i think + +0:01:44.720,0:01:47.920 +and that's why is that they know + +0:01:46.079,0:01:49.600 +integrated with common third party + +0:01:47.920,0:01:51.520 +extension i'm talking about company for + +0:01:49.600,0:01:55.360 +example third party + +0:01:51.520,0:01:57.280 +yeah you know the alpa melba packages + +0:01:55.360,0:01:58.719 +so uh this stock is going to be divided + +0:01:57.280,0:02:00.799 +in two parts the first one is going to + +0:01:58.719,0:02:03.040 +be how i maximize my date today + +0:02:00.799,0:02:03.840 +in max exercise don't worry it's going + +0:02:03.040,0:02:06.000 +to be + +0:02:03.840,0:02:07.680 +quite easy and the second one is going + +0:02:06.000,0:02:10.560 +to be why for the package + +0:02:07.680,0:02:13.200 +and the list improvement that i did and + +0:02:10.560,0:02:14.480 +a couple of things more maybe the future + +0:02:13.200,0:02:16.720 +and where's the package right now if you + +0:02:14.480,0:02:19.440 +can use it so + +0:02:16.720,0:02:21.360 +let's talk about the workflow so right + +0:02:19.440,0:02:23.040 +out of the box it has like an + +0:02:21.360,0:02:24.400 +orimal support i didn't write this it + +0:02:23.040,0:02:27.680 +was already + +0:02:24.400,0:02:30.319 +in emacs + +0:02:27.680,0:02:32.720 +so that's pretty nice let's go with a + +0:02:30.319,0:02:34.480 +simple example + +0:02:32.720,0:02:36.000 +okay so this is an array of three + +0:02:34.480,0:02:37.920 +equations and three variables + +0:02:36.000,0:02:39.840 +so it's a system that can be solved and + +0:02:37.920,0:02:42.560 +the solution is unique + +0:02:39.840,0:02:44.120 +um so we're going to solve it right + +0:02:42.560,0:02:47.519 +let's go + +0:02:44.120,0:02:48.080 +solutions okay here's how you define a + +0:02:47.519,0:02:52.400 +variable + +0:02:48.080,0:02:52.400 +in it's called solve okay + +0:02:52.640,0:03:00.400 +it's called implicit explicit + +0:02:56.480,0:03:03.680 +sorry okay and now an array of + +0:03:00.400,0:03:05.760 +our variables actually okay + +0:03:03.680,0:03:07.599 +so first of all we have to send this + +0:03:05.760,0:03:10.400 +variable to the maxima + +0:03:07.599,0:03:11.200 +repo with we can do that with ctrl c + +0:03:10.400,0:03:14.480 +control c + +0:03:11.200,0:03:19.200 +or with the maxima send line + +0:03:14.480,0:03:20.560 +okay so let's um let's put the maxima + +0:03:19.200,0:03:23.680 +buffer right here + +0:03:20.560,0:03:25.360 +okay let's so um + +0:03:23.680,0:03:27.040 +right now we can get the solution like + +0:03:25.360,0:03:29.360 +this so we call already + +0:03:27.040,0:03:30.239 +uh we call this line right now control + +0:03:29.360,0:03:31.920 +sequence to c + +0:03:30.239,0:03:33.440 +as you can see we get like an array + +0:03:31.920,0:03:36.080 +inside an array because + +0:03:33.440,0:03:38.799 +uh let's see why we get this so we can + +0:03:36.080,0:03:42.239 +call maxima + +0:03:38.799,0:03:44.879 +help a point this will open a + +0:03:42.239,0:03:46.000 +dock um buffer with all information + +0:03:44.879,0:03:48.799 +about the + +0:03:46.000,0:03:51.360 +solve function so we can see that this + +0:03:48.799,0:03:54.560 +list of solution equations + +0:03:51.360,0:03:56.640 +you can see it okay so but we no we know + +0:03:54.560,0:03:58.239 +that this system only have one solution + +0:03:56.640,0:04:00.400 +so we're only interested in the first + +0:03:58.239,0:04:02.080 +one we can do this like pretty easily + +0:04:00.400,0:04:05.120 +just to take the first one + +0:04:02.080,0:04:06.640 +we can send it to the buffer so this is + +0:04:05.120,0:04:09.280 +quite easy example as you can see + +0:04:06.640,0:04:10.400 +they have to completion much of the help + +0:04:09.280,0:04:12.319 +facilities that we have + +0:04:10.400,0:04:14.720 +we can also get information about the + +0:04:12.319,0:04:17.440 +symbol for example maxima + +0:04:14.720,0:04:17.840 +symbol doc and we get in the and now you + +0:04:17.440,0:04:19.840 +can see + +0:04:17.840,0:04:20.959 +correctly in the mini buffer all the + +0:04:19.840,0:04:24.080 +possible + +0:04:20.959,0:04:28.000 +um parameter of the function + +0:04:24.080,0:04:31.440 +right so let's continue + +0:04:28.000,0:04:34.880 +okay so let's go to a more well + +0:04:31.440,0:04:38.560 +complicated example to say oops + +0:04:34.880,0:04:42.400 +okay so we have this + +0:04:38.560,0:04:43.919 +equation and we want to go from -1 to 5 + +0:04:42.400,0:04:46.400 +i want to show in a nice + +0:04:43.919,0:04:47.759 +graph right first of all we begin + +0:04:46.400,0:04:51.759 +sending this line to the + +0:04:47.759,0:04:54.880 +maxima ripple hold it button again + +0:04:51.759,0:04:56.960 +okay um so this is not ideal if you want + +0:04:54.880,0:05:00.160 +to write down this equation because + +0:04:56.960,0:05:03.039 +it's quite messy what is when so + +0:05:00.160,0:05:04.479 +uh what's thing are where so we can call + +0:05:03.039,0:05:07.520 +the function maxima + +0:05:04.479,0:05:10.240 +let's say insert form okay + +0:05:07.520,0:05:11.280 +and this is more easy this basically put + +0:05:10.240,0:05:14.240 +text behind + +0:05:11.280,0:05:15.120 +and led or mode to render it and this is + +0:05:14.240,0:05:19.039 +quite easy to + +0:05:15.120,0:05:22.560 +write down you can use it like in every + +0:05:19.039,0:05:23.199 +expression so um first we have to call a + +0:05:22.560,0:05:27.280 +library + +0:05:23.199,0:05:29.199 +let's load the library library draw + +0:05:27.280,0:05:31.520 +we have also completion for local + +0:05:29.199,0:05:35.039 +variable and local + +0:05:31.520,0:05:38.240 +libraries sorry let me try to finish + +0:05:35.039,0:05:40.320 +draw okay and we send the line + +0:05:38.240,0:05:42.240 +so right now we have a leverage and we + +0:05:40.320,0:05:43.600 +should even have auto completion for the + +0:05:42.240,0:05:47.039 +library function + +0:05:43.600,0:05:50.400 +okay we have let's call draw2d + +0:05:47.039,0:05:51.199 +and now we can call implicit we should + +0:05:50.400,0:05:54.400 +have + +0:05:51.199,0:05:57.520 +okay and we can i mean put the variable + +0:05:54.400,0:05:58.639 +of equations we put the first variable d + +0:05:57.520,0:06:02.319 +minus + +0:05:58.639,0:06:05.280 +five d five five + +0:06:02.319,0:06:06.639 +the v variable the minus five and the + +0:06:05.280,0:06:09.680 +five + +0:06:06.639,0:06:11.759 +okay it should be all all good so let me + +0:06:09.680,0:06:14.639 +try to send it + +0:06:11.759,0:06:16.639 +okay you cannot see it right now because + +0:06:14.639,0:06:19.360 +i'm just sharing the maxima screen let + +0:06:16.639,0:06:23.520 +me try to change that + +0:06:19.360,0:06:27.199 +okay um + +0:06:23.520,0:06:27.199 +okay can you plot hello + +0:06:31.520,0:06:35.440 +okay so this is basically the graph that + +0:06:33.919,0:06:38.800 +i can upload generates + +0:06:35.440,0:06:41.039 +uh right now it's not integrated into + +0:06:38.800,0:06:42.240 +into the maximum package but it's a work + +0:06:41.039,0:06:46.000 +in progress + +0:06:42.240,0:06:50.160 +so let's go back to emacs + +0:06:46.000,0:06:53.520 +uh where are you okay there you are okay + +0:06:50.160,0:06:56.639 +okay so um + +0:06:53.520,0:06:57.759 +let's continue so uh this is some of the + +0:06:56.639,0:07:00.000 +things that you can use + +0:06:57.759,0:07:01.919 +for your day-to-day programming in + +0:07:00.000,0:07:05.680 +maxima + +0:07:01.919,0:07:05.680 +let's go now with the + +0:07:05.759,0:07:08.880 +okay as you can see this is just text + +0:07:07.360,0:07:11.199 +that is render + +0:07:08.880,0:07:13.440 +okay let's go within a slide this is how + +0:07:11.199,0:07:14.400 +i use maxima a simple example you don't + +0:07:13.440,0:07:16.240 +want to + +0:07:14.400,0:07:17.919 +talk too much about it because everyone + +0:07:16.240,0:07:19.680 +use the package in a different way + +0:07:17.919,0:07:21.039 +so right now i'm going to talk about the + +0:07:19.680,0:07:23.520 +original package and + +0:07:21.039,0:07:25.120 +the way i change it right so the + +0:07:23.520,0:07:27.840 +documentation + +0:07:25.120,0:07:29.680 +of the original was great but for me it + +0:07:27.840,0:07:31.840 +wasn't embedded in the code + +0:07:29.680,0:07:33.599 +it was something sometimes hard to read + +0:07:31.840,0:07:36.319 +like it was like a big + +0:07:33.599,0:07:37.039 +chunk of comment it gave me all the + +0:07:36.319,0:07:40.400 +information + +0:07:37.039,0:07:44.240 +like um for me that's too much i prefer + +0:07:40.400,0:07:45.360 +a cohesive small comment and then a big + +0:07:44.240,0:07:47.759 +redmi will order + +0:07:45.360,0:07:48.960 +all the links and information so that's + +0:07:47.759,0:07:52.080 +one of the first thing i + +0:07:48.960,0:07:52.560 +change um then also completion i'm a big + +0:07:52.080,0:07:55.759 +fan + +0:07:52.560,0:07:58.639 +i'm used to slime so i'm i love + +0:07:55.759,0:08:00.160 +great auto completion so um the first + +0:07:58.639,0:08:01.840 +thing that i noticed that well + +0:08:00.160,0:08:04.479 +it uses an absolute function i don't + +0:08:01.840,0:08:07.039 +know if you can see correctly okay + +0:08:04.479,0:08:08.800 +comment dynamic is deprecated and it + +0:08:07.039,0:08:10.720 +also have like this + +0:08:08.800,0:08:12.720 +variable which is maximus symbol which + +0:08:10.720,0:08:16.160 +is basically a big + +0:08:12.720,0:08:19.280 +list of all the possible completions so + +0:08:16.160,0:08:20.960 +if i load the library it's not aware of + +0:08:19.280,0:08:23.039 +the new symbols or even if i + +0:08:20.960,0:08:24.240 +create a variable it's not loaded so + +0:08:23.039,0:08:26.160 +it's not dynamic + +0:08:24.240,0:08:28.319 +so i want the first thing i want is + +0:08:26.160,0:08:31.680 +dynamic completion right + +0:08:28.319,0:08:34.159 +so i improve it which wasn't that hard + +0:08:31.680,0:08:36.080 +i first of all create maximum completion + +0:08:34.159,0:08:38.479 +which we're going to see in a moment + +0:08:36.080,0:08:39.200 +and then it changes completion region so + +0:08:38.479,0:08:41.039 +this is the + +0:08:39.200,0:08:43.760 +improved version but the good thing is + +0:08:41.039,0:08:45.839 +like i decoupled the completion function + +0:08:43.760,0:08:47.600 +so i make that you can use it on your + +0:08:45.839,0:08:50.800 +own so you get a prefix + +0:08:47.600,0:08:52.560 +which is um like + +0:08:50.800,0:08:55.040 +the thing that you're going to also + +0:08:52.560,0:08:56.959 +complete you get the inferior process + +0:08:55.040,0:08:58.959 +which i'm going to talk about later but + +0:08:56.959,0:08:59.760 +basically it's a maxima process you can + +0:08:58.959,0:09:01.760 +work with + +0:08:59.760,0:09:03.040 +and you get an optional argument which + +0:09:01.760,0:09:06.399 +is fuzzy finding + +0:09:03.040,0:09:07.200 +okay so you can easily send a block here + +0:09:06.399,0:09:10.399 +what + +0:09:07.200,0:09:11.440 +uh with the propos which is a maxima + +0:09:10.399,0:09:13.839 +command that gets you + +0:09:11.440,0:09:14.959 +all the auto completion and then you + +0:09:13.839,0:09:18.240 +process the + +0:09:14.959,0:09:20.480 +the output and you return a list + +0:09:18.240,0:09:21.600 +of possible completion this function can + +0:09:20.480,0:09:24.800 +be easily put into + +0:09:21.600,0:09:26.640 +company as you can see you just + +0:09:24.800,0:09:28.560 +get maximum auxiliary inferior process + +0:09:26.640,0:09:32.080 +is a process that just + +0:09:28.560,0:09:35.360 +uses sorry i have of + +0:09:32.080,0:09:36.480 +all the apropos and the get that symbol + +0:09:35.360,0:09:39.440 +it's like uh + +0:09:36.480,0:09:41.360 +like you say auxiliary let's help me uh + +0:09:39.440,0:09:43.680 +for that dirty stuff + +0:09:41.360,0:09:44.640 +so and process manipulation let's talk + +0:09:43.680,0:09:46.959 +about + +0:09:44.640,0:09:47.920 +how the maxima process was in the + +0:09:46.959,0:09:50.720 +beginning + +0:09:47.920,0:09:52.560 +so at first it was just one process and + +0:09:50.720,0:09:54.560 +you send all of the things there + +0:09:52.560,0:09:56.320 +and you move the processor here and + +0:09:54.560,0:09:58.160 +there and + +0:09:56.320,0:09:59.600 +there was a global state right so all + +0:09:58.160,0:10:02.000 +the function depends on + +0:09:59.600,0:10:05.120 +variable global variables and i don't + +0:10:02.000,0:10:07.680 +like that approach i prefer more like a + +0:10:05.120,0:10:09.519 +shirt to say functional like you sense + +0:10:07.680,0:10:12.000 +one of things and you return + +0:10:09.519,0:10:13.440 +something so it's not like a void + +0:10:12.000,0:10:16.399 +function so to say + +0:10:13.440,0:10:18.079 +so i change it recipe uh well this is + +0:10:16.399,0:10:20.959 +the maxima start function now + +0:10:18.079,0:10:22.560 +let's just create a startup process with + +0:10:20.959,0:10:23.680 +this function which is maxima make + +0:10:22.560,0:10:26.880 +inferior + +0:10:23.680,0:10:30.000 +so this function just gets a name + +0:10:26.880,0:10:31.519 +and it return a process of maxima and + +0:10:30.000,0:10:32.240 +you can then manipulate it the way you + +0:10:31.519,0:10:35.600 +want + +0:10:32.240,0:10:36.800 +let's see a better version so this is + +0:10:35.600,0:10:39.200 +the opposite right this + +0:10:36.800,0:10:41.760 +remove an inferior process and delete + +0:10:39.200,0:10:43.440 +the process and kill the buffer + +0:10:41.760,0:10:45.519 +right so let's give an example because + +0:10:43.440,0:10:46.399 +this you can see pretty easily in this + +0:10:45.519,0:10:50.079 +example + +0:10:46.399,0:10:51.519 +so i want to go to the scratch buffer + +0:10:50.079,0:10:54.399 +which i think you can see it better + +0:10:51.519,0:10:55.760 +okay so this is the way you can get a + +0:10:54.399,0:10:58.320 +process with your name + +0:10:55.760,0:11:00.880 +and save it into a variable right let's + +0:10:58.320,0:11:02.880 +execute this so as you can see well + +0:11:00.880,0:11:03.920 +i don't know if you can see big you get + +0:11:02.880,0:11:05.839 +a process + +0:11:03.920,0:11:07.040 +let's go to it the process called my + +0:11:05.839,0:11:09.519 +maxima + +0:11:07.040,0:11:10.079 +as the buffer right and if we can you + +0:11:09.519,0:11:12.240 +can send + +0:11:10.079,0:11:14.959 +stuff to the process right we can call + +0:11:12.240,0:11:16.880 +maximus in block get a block of valid + +0:11:14.959,0:11:17.760 +maxima code and just pass the variable + +0:11:16.880,0:11:20.800 +the process + +0:11:17.760,0:11:21.519 +and we send code to the process right we + +0:11:20.800,0:11:23.440 +can + +0:11:21.519,0:11:25.760 +this is useful if you have some + +0:11:23.440,0:11:28.480 +expensive computation that you want + +0:11:25.760,0:11:29.680 +to process laser to say so the process + +0:11:28.480,0:11:32.640 +can manage it + +0:11:29.680,0:11:33.920 +and when you get the results correctly + +0:11:32.640,0:11:34.399 +you can also get the result from the + +0:11:33.920,0:11:35.920 +process + +0:11:34.399,0:11:38.000 +i mean i don't put it here but quite + +0:11:35.920,0:11:41.200 +easy and then you + +0:11:38.000,0:11:42.079 +removed in favor which is the way to get + +0:11:41.200,0:11:43.600 +rid of the process + +0:11:42.079,0:11:45.279 +and the buffer so if we call this + +0:11:43.600,0:11:48.399 +function we should get rid of the + +0:11:45.279,0:11:49.920 +this process and it works the processing + +0:11:48.399,0:11:54.160 +is no longer + +0:11:49.920,0:11:56.160 +i'm happy to continue so um + +0:11:54.160,0:11:57.680 +other things that improve the package on + +0:11:56.160,0:11:59.760 +my commitment during time + +0:11:57.680,0:12:01.360 +i'm going good okay another thing that i + +0:11:59.760,0:12:02.560 +did to the package was to add + +0:12:01.360,0:12:04.959 +continue integration and continue + +0:12:02.560,0:12:06.320 +delivery right so the package didn't + +0:12:04.959,0:12:09.440 +have any tests + +0:12:06.320,0:12:12.959 +and the code was a little bit messy so + +0:12:09.440,0:12:16.560 +i add integration a test + +0:12:12.959,0:12:19.519 +and test with the test simple framework + +0:12:16.560,0:12:20.560 +from rocky bursting the maintainer of + +0:12:19.519,0:12:23.279 +real + +0:12:20.560,0:12:24.079 +good which is a great package by the way + +0:12:23.279,0:12:25.920 +um + +0:12:24.079,0:12:28.079 +yeah this is one example of the process + +0:12:25.920,0:12:29.760 +so right now because um + +0:12:28.079,0:12:31.680 +the infrastructure of the process + +0:12:29.760,0:12:33.680 +management is decoupled + +0:12:31.680,0:12:35.200 +so i can test it pretty easily this is + +0:12:33.680,0:12:37.519 +the test function of the + +0:12:35.200,0:12:39.519 +inferior running so i can check if an + +0:12:37.519,0:12:41.440 +inferior is running right now + +0:12:39.519,0:12:43.200 +and i can just delete it after and get + +0:12:41.440,0:12:45.279 +the results + +0:12:43.200,0:12:46.959 +and i also did some integration with the + +0:12:45.279,0:12:48.639 +party packages the first one company of + +0:12:46.959,0:12:50.880 +course i love auto completion + +0:12:48.639,0:12:53.839 +the second one was hormone that was + +0:12:50.880,0:12:56.880 +already there and latex with the + +0:12:53.839,0:13:00.079 +um or logic insert form + +0:12:56.880,0:13:02.959 +and with poly mode because um let me + +0:13:00.079,0:13:03.680 +evaluate this maxima can understand lisp + +0:13:02.959,0:13:06.959 +code + +0:13:03.680,0:13:10.000 +well more or less it has like a + +0:13:06.959,0:13:11.279 +function so to say that you can send a + +0:13:10.000,0:13:13.600 +list command to the + +0:13:11.279,0:13:14.480 +maxima rebel and you can understand it + +0:13:13.600,0:13:17.839 +in some way so + +0:13:14.480,0:13:20.959 +we can go to the maxima poly + +0:13:17.839,0:13:22.800 +only maxima right you enable polymaxima + +0:13:20.959,0:13:25.519 +and it creates a polymode + +0:13:22.800,0:13:26.399 +which this is lisp code and this is + +0:13:25.519,0:13:28.639 +maxima code + +0:13:26.399,0:13:30.560 +so we can send this to the maxima ripple + +0:13:28.639,0:13:34.240 +we come to c control r which + +0:13:30.560,0:13:37.760 +it sends the um the current + +0:13:34.240,0:13:40.160 +um area region sorry + +0:13:37.760,0:13:41.839 +and we define a variable which is called + +0:13:40.160,0:13:44.000 +test and as we can see we have the + +0:13:41.839,0:13:47.360 +variable test right here so you can + +0:13:44.000,0:13:48.079 +program in lisp and you can send it to + +0:13:47.360,0:13:50.399 +maxima + +0:13:48.079,0:13:51.920 +so this is pretty good pretty nice um + +0:13:50.399,0:13:55.040 +working integration with + +0:13:51.920,0:13:57.120 +the slime mode and with swank so you can + +0:13:55.040,0:13:59.120 +actually have a completion of + +0:13:57.120,0:14:00.959 +a function inside the maximal list + +0:13:59.120,0:14:02.800 +package but + +0:14:00.959,0:14:04.399 +this is going to take quite a while + +0:14:02.800,0:14:07.360 +because it's not trivial + +0:14:04.399,0:14:09.440 +so um we're the feature of maxima right + +0:14:07.360,0:14:11.519 +now well we have fonts highlighting + +0:14:09.440,0:14:14.480 +smart indentation uh it was already in + +0:14:11.519,0:14:16.880 +the package but now it's quite better + +0:14:14.480,0:14:18.160 +great help functions right now i can + +0:14:16.880,0:14:20.800 +find the recommendation quite + +0:14:18.160,0:14:22.160 +fast and currently the menu integration + +0:14:20.800,0:14:23.120 +this is quite basic it needs to be a + +0:14:22.160,0:14:25.199 +little bit improved + +0:14:23.120,0:14:26.720 +uh latex support also completion the + +0:14:25.199,0:14:28.480 +company and maximizer process + +0:14:26.720,0:14:29.120 +integration and mini buffer i didn't + +0:14:28.480,0:14:32.880 +show you + +0:14:29.120,0:14:34.639 +but basically if you call global maxima + +0:14:32.880,0:14:36.720 +minor mode you have the minor mode you + +0:14:34.639,0:14:38.399 +call maxima mini buffer + +0:14:36.720,0:14:40.720 +how are you okay mini buffer you can + +0:14:38.399,0:14:42.720 +basically just write simple maxima + +0:14:40.720,0:14:45.920 +command and it will give you the result + +0:14:42.720,0:14:48.959 +this is like a permanent version of um + +0:14:45.920,0:14:50.560 +calc so you can do it you write the + +0:14:48.959,0:14:52.320 +command and you get the output uh way + +0:14:50.560,0:14:56.079 +more to come i have like a list + +0:14:52.320,0:14:58.880 +of issues that i put enhancement a new + +0:14:56.079,0:15:01.199 +feature that i'm going to develop + +0:14:58.880,0:15:03.120 +so uh the future under presence of the + +0:15:01.199,0:15:06.880 +package well the package is right now + +0:15:03.120,0:15:10.720 +melpa a melba stable um + +0:15:06.880,0:15:13.360 +in this 0.7.6 version + +0:15:10.720,0:15:15.279 +and i'm planning to include into the + +0:15:13.360,0:15:16.720 +known canoe alpha + +0:15:15.279,0:15:18.959 +this is the url of the package by the + +0:15:16.720,0:15:20.079 +way so you can if you go to metapod you + +0:15:18.959,0:15:22.160 +put maxima and + +0:15:20.079,0:15:23.199 +you can download it it doesn't have too + +0:15:22.160,0:15:26.639 +much dependencies + +0:15:23.199,0:15:27.120 +you aware of that um and thank you very + +0:15:26.639,0:15:28.720 +much + +0:15:27.120,0:15:30.959 +uh this is going to be my talk these are + +0:15:28.720,0:15:33.519 +my uh information + +0:15:30.959,0:15:34.000 +this is my gitlab this is my page which + +0:15:33.519,0:15:37.120 +i don't + +0:15:34.000,0:15:40.240 +love too much and this is my email + +0:15:37.120,0:15:41.839 +so um thank you very much and i will be + +0:15:40.240,0:15:44.720 +answering some questions right now + +0:15:41.839,0:15:44.720 +and happy hacking + +0:15:45.600,0:15:52.720 +you are now unmuted thank you very much + +0:15:49.600,0:15:55.759 +vermin for the great talk um okay yeah + +0:15:52.720,0:15:58.800 +let's see if you have any questions + +0:15:55.759,0:16:01.759 +uh yeah i'm reading like this um + +0:15:58.800,0:16:04.079 +so i'm a buddy october usually right now + +0:16:01.759,0:16:04.079 +okay + +0:16:04.560,0:16:08.639 +maxima over october yep there are a + +0:16:06.880,0:16:11.519 +couple questions + +0:16:08.639,0:16:12.160 +wow maxima we're okay i don't want to i + +0:16:11.519,0:16:13.940 +don't know + +0:16:12.160,0:16:15.680 +october that much um + +0:16:13.940,0:16:17.839 +[Music] + +0:16:15.680,0:16:18.880 +like i use it like a couple of times but + +0:16:17.839,0:16:24.000 +i'm not happy + +0:16:18.880,0:16:27.120 +and i found the octave packets to be + +0:16:24.000,0:16:31.519 +quite a little bit harder to understand + +0:16:27.120,0:16:33.839 +and also that + +0:16:31.519,0:16:35.680 +it didn't have too much features like i + +0:16:33.839,0:16:37.839 +prefer the maximum used to + +0:16:35.680,0:16:38.880 +maybe octave is better i don't i'm not + +0:16:37.839,0:16:40.800 +100 sure + +0:16:38.880,0:16:42.079 +i know that you can use it for similar + +0:16:40.800,0:16:45.920 +stuff but + +0:16:42.079,0:16:45.920 +that's it so sorry + +0:16:47.120,0:16:54.079 +okay i'm in a little bit of a rush sorry + +0:16:50.959,0:16:56.399 +let me drink a little blue okay + +0:16:54.079,0:16:56.399 +okay + +0:17:00.639,0:17:08.000 +okay how does maxima compare to sagemath + +0:17:05.280,0:17:08.000 +in imax + +0:17:08.959,0:17:17.439 +i mean i don't know what is sage + +0:17:13.360,0:17:18.079 +math i'm sorry um so i cannot answer + +0:17:17.439,0:17:21.839 +your question + +0:17:18.079,0:17:25.039 +with your question i think um + +0:17:21.839,0:17:26.720 +sorry but i mean maxima is ready in + +0:17:25.039,0:17:28.000 +combo list that's just a preference for + +0:17:26.720,0:17:31.120 +me because i like + +0:17:28.000,0:17:35.520 +lisp dialect and common lisp is + +0:17:31.120,0:17:35.520 +interesting um + +0:17:36.400,0:17:42.720 +yeah do you plan to + +0:17:40.480,0:17:43.840 +i mean a maximum organization for maxima + +0:17:42.720,0:17:47.360 +code block + +0:17:43.840,0:17:50.720 +yes i want to improve the um + +0:17:47.360,0:17:52.000 +of maxima package but i didn't have + +0:17:50.720,0:17:54.400 +enough time and i want to + +0:17:52.000,0:17:57.200 +clear a little bit of the code because + +0:17:54.400,0:17:57.200 +still right now + +0:17:58.000,0:18:02.080 +the code is quite messy in some areas + +0:18:00.080,0:18:03.520 +because i pretty much implement first + +0:18:02.080,0:18:05.600 +the base function i want to + +0:18:03.520,0:18:07.120 +build on top of so right now it's quite + +0:18:05.600,0:18:07.919 +usable but i still have something that i + +0:18:07.120,0:18:11.120 +want to improve + +0:18:07.919,0:18:14.799 +so when i finish that i will + +0:18:11.120,0:18:16.640 +improve the normal version i think + +0:18:14.799,0:18:18.640 +it's maximizing to get into into your + +0:18:16.640,0:18:21.200 +opinion yes i + +0:18:18.640,0:18:21.919 +i think that the creator of maxima like + +0:18:21.200,0:18:26.400 +have this + +0:18:21.919,0:18:26.400 +lisp mine and probably + +0:18:26.640,0:18:30.559 +that they if you go to a symbol you get + +0:18:29.520,0:18:33.520 +all the information + +0:18:30.559,0:18:36.480 +and that reflects that you can actually + +0:18:33.520,0:18:40.000 +write your program of maxima into + +0:18:36.480,0:18:40.799 +um into lisp literally because they have + +0:18:40.000,0:18:42.480 +a command + +0:18:40.799,0:18:44.880 +so i think that is quite easy to get + +0:18:42.480,0:18:48.240 +into some university use it for + +0:18:44.880,0:18:51.200 +um first um + +0:18:48.240,0:18:53.039 +years so it's quite easy and i think + +0:18:51.200,0:18:56.640 +with my package you can use it + +0:18:53.039,0:18:58.960 +like pretty pretty easily just create a + +0:18:56.640,0:19:00.880 +file and you can start typing and + +0:18:58.960,0:19:04.400 +maximize quite easy to install also + +0:19:00.880,0:19:07.600 +so i think yeah it's crazy and + +0:19:04.400,0:19:10.080 +the page should restart i don't know why + +0:19:07.600,0:19:10.080 +sorry + +0:19:18.320,0:19:25.440 +strict in fixed lisp syntax + +0:19:22.559,0:19:26.240 +you're talking about the maxima itself + +0:19:25.440,0:19:27.760 +syntax + +0:19:26.240,0:19:30.160 +or i don't understand the question + +0:19:27.760,0:19:30.160 +correctly + +0:19:32.240,0:19:35.440 +well i'm going to go to the next + +0:19:33.679,0:19:37.360 +question is there + +0:19:35.440,0:19:38.880 +support for images in maximum mode not + +0:19:37.360,0:19:43.840 +right now + +0:19:38.880,0:19:43.840 +the way i want to implement some imax + +0:19:45.280,0:19:51.280 +things uh is there support for + +0:19:49.120,0:19:53.360 +but right now it doesn't have like a if + +0:19:51.280,0:19:55.600 +you could want to have a new plot + +0:19:53.360,0:19:56.720 +um inside you buffer right now it's not + +0:19:55.600,0:19:59.360 +possible so + +0:19:56.720,0:20:01.200 +that's the thing that i maximized that + +0:19:59.360,0:20:03.520 +maxima.l still doesn't + +0:20:01.200,0:20:04.720 +do which university you start to use + +0:20:03.520,0:20:08.799 +maxima um + +0:20:04.720,0:20:11.840 +in this aragosa university from spain + +0:20:08.799,0:20:12.640 +they used to maximize the um thing in + +0:20:11.840,0:20:16.400 +the engineer + +0:20:12.640,0:20:18.320 +and in the math also so i'm 100 sure + +0:20:16.400,0:20:19.679 +right now but when i started + +0:20:18.320,0:20:22.559 +are you planning to option your package + +0:20:19.679,0:20:25.440 +into maxima um i don't know about that + +0:20:22.559,0:20:26.320 +because uh maybe can be a little bit + +0:20:25.440,0:20:30.720 +messy + +0:20:26.320,0:20:32.960 +um because the maxima ripple is more + +0:20:30.720,0:20:33.360 +built around like maxima itself and they + +0:20:32.960,0:20:37.600 +don't + +0:20:33.360,0:20:42.240 +update the interfaces that much + +0:20:37.600,0:20:45.360 +i have no problem like it's okay it just + +0:20:42.240,0:20:46.320 +you have to um if you want to push you + +0:20:45.360,0:20:48.480 +can push in other + +0:20:46.320,0:20:49.520 +repository i mean it's just changed the + +0:20:48.480,0:20:52.880 +file another way + +0:20:49.520,0:20:54.080 +but also the test um is going to be a + +0:20:52.880,0:20:55.200 +little bit harder because i think + +0:20:54.080,0:20:59.120 +they're using + +0:20:55.200,0:21:01.200 +search for and i'm using + +0:20:59.120,0:21:02.159 +git lab continue integration within the + +0:21:01.200,0:21:06.799 +jury + +0:21:02.159,0:21:09.679 +so yeah i don't think that now unmuted + +0:21:06.799,0:21:09.679 +yeah it will be nice + +0:21:10.799,0:21:14.840 +okay um it's possible to include + +0:21:12.799,0:21:16.480 +maximizing or false similar to jupiter + +0:21:14.840,0:21:19.919 +notebooks + +0:21:16.480,0:21:23.280 +um i mean you can uh use maximize

the imax application filter + +0:01:26.880,0:01:30.400 +which i help to maintain along with the + +0:01:29.119,0:01:33.040 +other other + +0:01:30.400,0:01:35.360 +lazy cat which of course is today's + +0:01:33.040,0:01:35.360 +topic + +0:01:35.759,0:01:40.960 +so as you might all might have already + +0:01:38.720,0:01:43.600 +noticed i'm currently using emacs + +0:01:40.960,0:01:45.360 +and oh and opening navigating closing + +0:01:43.600,0:01:46.159 +all these websites that are rendered + +0:01:45.360,0:01:49.200 +properly + +0:01:46.159,0:01:51.840 +or within emacs it's all thanks to the + +0:01:49.200,0:01:54.000 +ef project + +0:01:51.840,0:01:55.920 +so we're living in a society that's + +0:01:54.000,0:01:59.520 +heavily dependent on the internet + +0:01:55.920,0:02:01.200 +and multimedia it is unavoidable to run + +0:01:59.520,0:02:02.880 +to some occasion that you need to + +0:02:01.200,0:02:04.799 +open a fancy website that uses + +0:02:02.880,0:02:08.239 +javascript and css + +0:02:04.799,0:02:11.120 +or you need to watch some videos however + +0:02:08.239,0:02:11.840 +due to the nature and history of emacs + +0:02:11.120,0:02:13.840 +it cannot + +0:02:11.840,0:02:16.400 +render all these modern graphics + +0:02:13.840,0:02:19.360 +effectively and efficiently + +0:02:16.400,0:02:20.400 +emacs is solely a text-based editing + +0:02:19.360,0:02:23.520 +environment + +0:02:20.400,0:02:25.680 +and i argue that this is not a bad thing + +0:02:23.520,0:02:27.760 +in fact it is one of the reasons that me + +0:02:25.680,0:02:29.760 +and i believe many of you as well + +0:02:27.760,0:02:30.879 +are attracted to emacs in the first + +0:02:29.760,0:02:33.760 +place + +0:02:30.879,0:02:35.680 +unfortunately this results in us having + +0:02:33.760,0:02:37.040 +to open a dedicated web browser to + +0:02:35.680,0:02:38.879 +browse the internet + +0:02:37.040,0:02:41.440 +open a dedicated video player to watch + +0:02:38.879,0:02:42.640 +some videos or a pdf render to read some + +0:02:41.440,0:02:45.200 +documents + +0:02:42.640,0:02:46.000 +so far ems cannot do all these tasks on + +0:02:45.200,0:02:48.080 +its own + +0:02:46.000,0:02:51.519 +but can only be achieved using other + +0:02:48.080,0:02:55.840 +external applications + +0:02:51.519,0:02:58.640 +so the other the author manatee lazy cat + +0:02:55.840,0:03:00.560 +or lazy cat in short didn't want to use + +0:02:58.640,0:03:03.120 +all these external applications + +0:03:00.560,0:03:04.159 +he wanted to have an uninterrupted e-max + +0:03:03.120,0:03:07.280 +experience + +0:03:04.159,0:03:10.080 +he wanted to truly live in e-max + +0:03:07.280,0:03:11.040 +however it would be a lot of work to + +0:03:10.080,0:03:13.519 +build this + +0:03:11.040,0:03:16.239 +modern application from scratch there's + +0:03:13.519,0:03:18.800 +simply no time or research to do that + +0:03:16.239,0:03:20.400 +so lazy car without utilizing existing + +0:03:18.800,0:03:22.319 +applications + +0:03:20.400,0:03:24.959 +and to try to make it collaborate with + +0:03:22.319,0:03:26.000 +emacs there are many solutions available + +0:03:24.959,0:03:28.560 +one of it + +0:03:26.000,0:03:30.159 +is the e-max x windows manager and i'm + +0:03:28.560,0:03:33.360 +sure a lot of you already know that + +0:03:30.159,0:03:35.200 +the exwm however it didn't work for him + +0:03:33.360,0:03:37.440 +because although ux doubling opens the + +0:03:35.200,0:03:38.239 +door to use other applications within + +0:03:37.440,0:03:40.879 +emacs + +0:03:38.239,0:03:41.519 +it as a fine window manager cannot + +0:03:40.879,0:03:43.920 +modify + +0:03:41.519,0:03:45.040 +customize or extend other software from + +0:03:43.920,0:03:46.799 +emacs + +0:03:45.040,0:03:48.480 +for example it cannot modify the + +0:03:46.799,0:03:49.599 +behavior when you press a key in + +0:03:48.480,0:03:52.159 +chromium or + +0:03:49.599,0:03:54.000 +pdf viewer therefore it cannot utilize + +0:03:52.159,0:03:57.360 +the rich emax ecosystem that's been + +0:03:54.000,0:04:00.720 +growing for almost 40 years + +0:03:57.360,0:04:03.760 +on the other hand in the ef browser so + +0:04:00.720,0:04:07.200 +if you mx ef open + +0:04:03.760,0:04:09.840 +browser with history you can see + +0:04:07.200,0:04:11.920 +on the lower half of my screen a list of + +0:04:09.840,0:04:14.560 +histories sorted by my personal + +0:04:11.920,0:04:16.560 +most visited sites and you can search + +0:04:14.560,0:04:19.440 +for a site that you've been + +0:04:16.560,0:04:21.840 +into or search for some keyword and in a + +0:04:19.440,0:04:24.240 +search engine + +0:04:21.840,0:04:25.919 +so this is all achieved by utilizing the + +0:04:24.240,0:04:29.120 +popular completion framework in the + +0:04:25.919,0:04:29.120 +emacs ecosystem + +0:04:29.280,0:04:33.680 +so this car decided to develop a + +0:04:31.120,0:04:36.960 +solution of its own in 2018 + +0:04:33.680,0:04:40.000 +namely the eaf project so i joined the + +0:04:36.960,0:04:40.000 +development last year + +0:04:40.840,0:04:47.880 +2019 ef is + +0:04:44.000,0:04:49.759 +a highly customizable and extensible + +0:04:47.880,0:04:52.160 +reapplication framework that extends + +0:04:49.759,0:04:57.840 +imax to graphical capabilities using pi + +0:04:52.160,0:05:02.479 +qd5 and it is not a window manager + +0:04:57.840,0:05:03.440 +alright so in the readme you can see a + +0:05:02.479,0:05:05.600 +list of gifs + +0:05:03.440,0:05:06.720 +showcasing all the available ef + +0:05:05.600,0:05:09.520 +applications + +0:05:06.720,0:05:10.960 +a browser a markdown premier a video + +0:05:09.520,0:05:14.240 +player + +0:05:10.960,0:05:16.160 +a pdf viewer and more today i don't have + +0:05:14.240,0:05:16.560 +enough time to demonstrate each one of + +0:05:16.160,0:05:18.720 +them + +0:05:16.560,0:05:21.120 +but i will select a couple applications + +0:05:18.720,0:05:24.240 +to show you + +0:05:21.120,0:05:27.840 +so since we are already using ef browser + +0:05:24.240,0:05:29.600 +we'll start with this besides using the + +0:05:27.840,0:05:32.000 +classic control n control p + +0:05:29.600,0:05:33.840 +you can also use the vim style xjkl to + +0:05:32.000,0:05:36.320 +move up or down + +0:05:33.840,0:05:37.280 +also meta shift comma or g to the + +0:05:36.320,0:05:39.120 +beginning of page + +0:05:37.280,0:05:41.199 +when that shift period or capital g to + +0:05:39.120,0:05:44.320 +the end of page + +0:05:41.199,0:05:46.479 +limiting and surfing keys linear and + +0:05:44.320,0:05:48.400 +surfing keys are popular keyboard-based + +0:05:46.479,0:05:50.479 +browsing techniques in chrome + +0:05:48.400,0:05:52.720 +and they've imported here as well you + +0:05:50.479,0:05:53.039 +can press f to toggle markers pointing + +0:05:52.720,0:05:55.280 +to + +0:05:53.039,0:05:56.960 +all the

your liking + +0:06:02.400,0:06:05.440 +so you see the marker on top of wiki is + +0:06:04.720,0:06:08.479 +dd + +0:06:05.440,0:06:10.240 +press dd and you enter and now + +0:06:08.479,0:06:13.680 +you will navigate it to this link so you + +0:06:10.240,0:06:13.680 +don't need to use your mouse at all + +0:06:13.840,0:06:17.680 +so a full list of key bindings can be + +0:06:16.560,0:06:20.560 +found when you + +0:06:17.680,0:06:21.199 +control hm just as any other max major + +0:06:20.560,0:06:22.960 +mode + +0:06:21.199,0:06:25.600 +so you don't have to remember everything + +0:06:22.960,0:06:28.560 +all the key bindings i said to you + +0:06:25.600,0:06:30.960 +so this is a global binding application + +0:06:28.560,0:06:34.319 +to every other ef application as well + +0:06:30.960,0:06:36.720 +so you can find it under the week or or + +0:06:34.319,0:06:37.600 +you can find it under the wiki in the + +0:06:36.720,0:06:40.639 +key binding + +0:06:37.600,0:06:44.240 +section so press f again and use + +0:06:40.639,0:06:45.600 +ns press enter now you're in the key + +0:06:44.240,0:06:47.520 +binding web page + +0:06:45.600,0:06:49.280 +you can see all of the key buttons + +0:06:47.520,0:06:53.919 +available in every + +0:06:49.280,0:06:56.479 +es application and you can try them out + +0:06:53.919,0:06:57.360 +and you can customize your key bindings + +0:06:56.479,0:07:00.240 +using ef + +0:06:57.360,0:07:02.960 +bank key you can customize control n as + +0:07:00.240,0:07:05.759 +in the web page to + +0:07:02.960,0:07:06.639 +to scroll up in the ef pdf viewer or you + +0:07:05.759,0:07:09.599 +can unbind + +0:07:06.639,0:07:10.000 +an existing binding using using yet bank + +0:07:09.599,0:07:14.800 +key + +0:07:10.000,0:07:14.800 +binder to new so it doesn't bind to + +0:07:14.840,0:07:20.319 +anything + +0:07:16.160,0:07:22.479 +okay so here comes the important part + +0:07:20.319,0:07:25.440 +if you want to customize ef you should +

+0:07:44.479,0:07:48.479 +mode for ef browser + +0:07:46.720,0:07:49.919 +and you don't want to use your mouse to + +0:07:48.479,0:07:53.360 +do all this stuff + +0:07:49.919,0:07:55.840 +you press c

+0:08:05.360,0:08:10.240 +in this case you want + +0:08:06.639,0:08:12.720 +ls which comes here + +0:08:10.240,0:08:15.120 +and then you just you just move the + +0:08:12.720,0:08:18.800 +cursor like what you always do + +0:08:15.120,0:08:23.280 +in emacs and now you select everything + +0:08:18.800,0:08:25.680 +and use meta w to + +0:08:23.280,0:08:26.479 +excuse me metadata to copy the taste the + +0:08:25.680,0:08:29.199 +text + +0:08:26.479,0:08:30.960 +now we made a shift column to evaluate + +0:08:29.199,0:08:35.120 +what we just copied + +0:08:30.960,0:08:38.320 +and set that to true and + +0:08:35.120,0:08:42.159 +press r or f5 to refresh the page + +0:08:38.320,0:08:44.880 +voila we have the dark mode enabled + +0:08:42.159,0:08:46.160 +so there are well let's take a toggle + +0:08:44.880,0:08:49.360 +back off for now + +0:08:46.160,0:08:51.600 +now we made our shift column again + +0:08:49.360,0:08:53.519 +and we find the the one we just used and + +0:08:51.600,0:08:56.880 +change it back to false + +0:08:53.519,0:08:59.120 +and refresh the page back in the light + +0:08:56.880,0:08:59.120 +mode + +0:08:59.360,0:09:03.680 +so there are many other customization + +0:09:02.160,0:09:05.920 +options available you can either + +0:09:03.680,0:09:08.000 +evaluate like what we just did or add it + +0:09:05.920,0:09:11.680 +to your emacs configuration file + +0:09:08.000,0:09:14.399 +so in this wiki you can have you can + +0:09:11.680,0:09:16.320 +you can make the ef browser to to + +0:09:14.399,0:09:20.160 +continue where you left off + +0:09:16.320,0:09:22.800 +similar to the chromium setting + +0:09:20.160,0:09:23.839 +and you can make yes the default browser + +0:09:22.800,0:09:26.720 +emacs by + +0:09:23.839,0:09:27.680 +aliasing aliasing browse web to your + +0:09:26.720,0:09:30.399 +open browser + +0:09:27.680,0:09:31.200 +or or set the browse url browser + +0:09:30.399,0:09:33.519 +function to + +0:09:31.200,0:09:34.480 +open browser there's just some tricks + +0:09:33.519,0:09:37.920 +and there are also + +0:09:34.480,0:09:41.680 +uh an experimental app blocker currently + +0:09:37.920,0:09:44.720 +take in place and so therefore it can + +0:09:41.680,0:09:47.279 +block some elements but not all so + +0:09:44.720,0:09:48.240 +we we really encourage people to help us + +0:09:47.279,0:09:51.440 +test out and + +0:09:48.240,0:09:54.560 +add more conditions in + +0:09:51.440,0:09:55.760 +so you can so the ef browser is able to + +0:09:54.560,0:09:57.680 +download + +0:09:55.760,0:09:59.920 +any files from the internet and it will + +0:09:57.680,0:10:04.000 +be downloaded using + +0:09:59.920,0:10:06.079 +a area too and + +0:10:04.000,0:10:07.200 +you can also customize the ef browser + +0:10:06.079,0:10:11.120 +download path + +0:10:07.200,0:10:14.399 +using ef set so it's a function that we + +0:10:11.120,0:10:15.040 +defined similar to set the normal set we + +0:10:14.399,0:10:16.480 +know + +0:10:15.040,0:10:18.160 +so by default the download file is + +0:10:16.480,0:10:19.600 +stored in your home directory slash + +0:10:18.160,0:10:20.800 +downloads + +0:10:19.600,0:10:22.720 +and you can change that whenever you + +0:10:20.800,0:10:26.079 +want you can also disable + +0:10:22.720,0:10:28.959 +saving browsing history so remember + +0:10:26.079,0:10:30.480 +when i press when i use mx you have open + +0:10:28.959,0:10:32.079 +browser's history i see all the + +0:10:30.480,0:10:33.680 +histories here but if you want more + +0:10:32.079,0:10:35.360 +privacy you don't want that to be + +0:10:33.680,0:10:36.560 +available at all you can turn it off + +0:10:35.360,0:10:38.720 +easily with ef + +0:10:36.560,0:10:40.640 +set queue and set that remember history + +0:10:38.720,0:10:42.399 +to false + +0:10:40.640,0:10:43.839 +you can also say your default search + +0:10:42.399,0:10:47.200 +engine so + +0:10:43.839,0:10:50.480 +so right now we have google although + +0:10:47.200,0:10:53.600 +not not really good but google and also + +0:10:50.480,0:10:57.360 +go which is a better search engine + +0:10:53.600,0:10:59.360 +well uh yeah ethically better search + +0:10:57.360,0:11:02.560 +engine + +0:10:59.360,0:11:05.040 +so you can also configure + +0:11:02.560,0:11:07.600 +the zoom so the default zoom of your + +0:11:05.040,0:11:10.000 +browser is 1.0 so you can convert + +0:11:07.600,0:11:11.920 +convert 3000 to 1.25 so you can so when + +0:11:10.000,0:11:14.079 +you open any web page about it will be + +0:11:11.920,0:11:17.360 +zoomed + +0:11:14.079,0:11:20.399 +by default uh you can + +0:11:17.360,0:11:22.240 +also disable javascript although i + +0:11:20.399,0:11:23.440 +personally don't really suggest you to + +0:11:22.240,0:11:26.240 +do because it will + +0:11:23.440,0:11:28.480 +basically break a lot of our features + +0:11:26.240,0:11:29.519 +because a lot of the browser browser + +0:11:28.480,0:11:33.600 +related features + +0:11:29.519,0:11:33.600 +must be implemented using javascript + +0:11:33.760,0:11:37.920 +but yeah you can do it if you really + +0:11:35.440,0:11:41.519 +want to and there also some + +0:11:37.920,0:11:45.519 +customization on ef camera + +0:11:41.519,0:11:45.519 +you can do as well yeah + +0:11:47.760,0:11:56.079 +so uh let's move on to efpd viewer + +0:11:52.399,0:11:59.440 +so now now let's open + +0:11:56.079,0:12:01.519 +the pdf file using af + +0:11:59.440,0:12:02.720 +so that's one something already here but + +0:12:01.519,0:12:06.079 +let's open it here + +0:12:02.720,0:12:08.160 +so yes open and + +0:12:06.079,0:12:11.440 +select introduction to programming in + +0:12:08.160,0:12:13.760 +e-max list + +0:12:11.440,0:12:16.800 +uh i have it already open but it's okay + +0:12:13.760,0:12:16.800 +so you have the file + +0:12:17.040,0:12:22.800 +you have other files displayed + +0:12:20.160,0:12:23.200

+0:14:57.120,0:15:02.639 +player + +0:14:58.880,0:15:03.279 +so mxef open if you use ef open whenever + +0:15:02.639,0:15:06.079 +you want to + +0:15:03.279,0:15:07.279 +open some file you use yet open browser + +0:15:06.079,0:15:09.920 +if you want to use some + +0:15:07.279,0:15:11.199 +actual application that's not really + +0:15:09.920,0:15:14.800 +related to a file + +0:15:11.199,0:15:15.600 +so you have open and select the video + +0:15:14.800,0:15:18.320 +you want so + +0:15:15.600,0:15:19.040 +video demo so i already have a video + +0:15:18.320,0:15:21.839 +demo + +0:15:19.040,0:15:22.720 +ready so because i recorded a video of + +0:15:21.839,0:15:26.000 +the demo + +0:15:22.720,0:15:28.079 +of the ef camera have a look so + +0:15:26.000,0:15:29.279 +let's move to the beginning hello people + +0:15:28.079,0:15:32.399 +from the future + +0:15:29.279,0:15:35.199 +this is a demo of the ef video player + +0:15:32.399,0:15:37.440 +that demos the ef camera feature + +0:15:35.199,0:15:38.639 +so as you can see on the screen of me + +0:15:37.440,0:15:40.959 +inside my camera + +0:15:38.639,0:15:42.880 +and the screen is actually with all + +0:15:40.959,0:15:46.079 +within emacs + +0:15:42.880,0:15:49.839 +right so and you can open this + +0:15:46.079,0:15:53.040 +using here open camera + +0:15:49.839,0:15:53.600 +and which i'm already into and you can + +0:15:53.040,0:15:56.720 +press + +0:15:53.600,0:15:59.680 +p to capture a photo + +0:15:56.720,0:16:00.880 +so the photo is by default stored at + +0:15:59.680,0:16:03.920 +your home slash + +0:16:00.880,0:16:04.320 +downloads directory and you can modify + +0:16:03.920,0:16:07.839 +it + +0:16:04.320,0:16:09.519 +freely so if you go here and you can see + +0:16:07.839,0:16:13.759 +the camera stored + +0:16:09.519,0:16:16.240 +right here so why what i used here + +0:16:13.759,0:16:17.120 +so you press space to pause what i used + +0:16:16.240,0:16:20.320 +here is + +0:16:17.120,0:16:22.959 +the year so ef open this entire so + +0:16:20.320,0:16:23.839 +basically so in direct you you go to you + +0:16:22.959,0:16:26.959 +you select + +0:16:23.839,0:16:30.320 +the file that should be opened by + +0:16:26.959,0:16:32.720 +eaf and i use that so it it detects that + +0:16:30.320,0:16:35.839 +it wants to use the ef image viewer so + +0:16:32.720,0:16:39.759 +i accidentally tested if image viewer + +0:16:35.839,0:16:40.240 +before i noticed so that that that gives + +0:16:39.759,0:16:43.680 +the + +0:16:40.240,0:16:47.040 +image of the photo i just took + +0:16:43.680,0:16:47.360 +using ef camera and as you can see you + +0:16:47.040,0:16:50.720 +can + +0:16:47.360,0:16:51.600 +i can use hl the bim button to navigate + +0:16:50.720,0:16:55.920 +in the time + +0:16:51.600,0:17:00.880 +timestamp in the video and i can use + +0:16:55.920,0:17:00.880 +jk to to change the volumes of the video + +0:17:02.320,0:17:06.160 +alright so now you've seen all the basic + +0:17:05.520,0:17:08.720 +usages + +0:17:06.160,0:17:11.600 +of the ef project it comes the question + +0:17:08.720,0:17:14.559 +of what is the magic behind it + +0:17:11.600,0:17:15.919 +all right let's open the hacking page in + +0:17:14.559,0:17:20.400 +the wiki + +0:17:15.919,0:17:24.799 +the design is laid out in a diagram here + +0:17:20.400,0:17:24.799 +so and let's put it + +0:17:25.120,0:17:28.160 +side by side along with my text so you + +0:17:27.839,0:17:32.320 +can + +0:17:28.160,0:17:36.080 +go we can follow through + +0:17:32.320,0:17:39.440 +right okay let me + +0:17:36.080,0:17:39.440 +sorry let me drink some water + +0:17:42.320,0:17:48.160 +so this page in the wiki went into a lot + +0:17:46.000,0:17:49.520 +of detail + +0:17:48.160,0:17:51.679 +due to the time constraint i will just + +0:17:49.520,0:17:53.520 +rephrase some of the ideas here so for + +0:17:51.679,0:17:55.600 +anyone interested please have a look at + +0:17:53.520,0:17:58.160 +the wiki yourself + +0:17:55.600,0:17:58.720 +the easiest way to think about eaf is + +0:17:58.160,0:18:01.679 +that + +0:17:58.720,0:18:02.960 +the actual gui application is started in + +0:18:01.679,0:18:04.960 +the background + +0:18:02.960,0:18:07.120 +then the frame of the application is + +0:18:04.960,0:18:07.679 +attached to the appropriate location on + +0:18:07.120,0:18:10.720 +the + +0:18:07.679,0:18:13.440 +emacs window so + +0:18:10.720,0:18:14.960 +you have linked qt5 with emacs using + +0:18:13.440,0:18:17.120 +list and python + +0:18:14.960,0:18:18.640 +of the python site which is colored + +0:18:17.120,0:18:20.559 +yellow in the image + +0:18:18.640,0:18:22.960 +you have two graphics view and queue + +0:18:20.559,0:18:25.039 +graphics scene objects + +0:18:22.960,0:18:26.640 +these are used to simulate the e-max + +0:18:25.039,0:18:28.640 +window buffer design + +0:18:26.640,0:18:29.840 +where q graphics scene is similar to + +0:18:28.640,0:18:31.840 +buffers in emacs + +0:18:29.840,0:18:34.240 +it controls the state and the content + +0:18:31.840,0:18:38.880 +details of the application + +0:18:34.240,0:18:38.880 +well q graphics view is similar to + +0:18:39.039,0:18:43.200 +geographic view is similar to imax + +0:18:41.200,0:18:45.919 +window it populates the buffer + +0:18:43.200,0:18:46.960 +to graphics scene to the full program at + +0:18:45.919,0:18:50.320 +the appropriate + +0:18:46.960,0:18:57.679 +position whenever an ef mode buffer + +0:18:50.320,0:18:59.679 +brings to a background + +0:18:57.679,0:19:00.880 +whenever an ef mode buffer brings to the + +0:18:59.679,0:19:02.559 +foreground sorry + +0:19:00.880,0:19:05.120 +a queue graphics view instance is + +0:19:02.559,0:19:06.080 +created and whenever the buffer goes to + +0:19:05.120,0:19:08.000 +the background + +0:19:06.080,0:19:09.120 +the q graphics view instance is then + +0:19:08.000,0:19:10.960 +deleted + +0:19:09.120,0:19:12.480 +while q graphics scene the actual + +0:19:10.960,0:19:14.480 +process remains running in the + +0:19:12.480,0:19:16.000 +background until the ef mode buffer is + +0:19:14.480,0:19:18.320 +killed + +0:19:16.000,0:19:19.440 +gpa compositing is used to ensure that q + +0:19:18.320,0:19:21.840 +graphics view and + +0:19:19.440,0:19:24.000 +graphics sync is synchronized real time + +0:19:21.840,0:19:25.679 +using q windows set parent function + +0:19:24.000,0:19:27.840 +the queue graphics view is attached to + +0:19:25.679,0:19:30.640 +appropriate location on the e-max frame + +0:19:27.840,0:19:32.400 +so that although great applications are + +0:19:30.640,0:19:35.760 +not running within e-max + +0:19:32.400,0:19:35.760 +they look as if they were + +0:19:36.160,0:19:41.039 +so when user types on the keyboard it is + +0:19:39.039,0:19:43.520 +first received by the emacs ef + +0:19:41.039,0:19:45.360 +ef mode buffer and then it lifts sends + +0:19:43.520,0:19:46.240 +the event to google graphics sync using + +0:19:45.360,0:19:48.720 +dbus + +0:19:46.240,0:19:50.400 +when user clicks on the gui application + +0:19:48.720,0:19:50.799 +it is received by the queue graphics + +0:19:50.400,0:19:53.280 +view + +0:19:50.799,0:19:55.200 +and process in python ellipse can + +0:19:53.280,0:19:59.200 +communicate with python through dbus + +0:19:55.200,0:20:01.360 +in other words in other words you can + +0:19:59.200,0:20:01.760 +customize and extend emacs not just + +0:20:01.360,0:20:04.480 +using + +0:20:01.760,0:20:05.360 +lisp and now you can use python this way + +0:20:04.480,0:20:07.039 +one can leverage + +0:20:05.360,0:20:09.600 +all the python properties like + +0:20:07.039,0:20:11.679 +multi-threading or some other stuff + +0:20:09.600,0:20:13.520 +the entire python ecosystem can be + +0:20:11.679,0:20:16.159 +utilized as well + +0:20:13.520,0:20:16.960 +such as the qt web engine that is the + +0:20:16.159,0:20:20.640 +basis for + +0:20:16.960,0:20:23.360 +our eef browser and pi mu pdf is the + +0:20:20.640,0:20:25.840 +basis for the ef pdf viewer + +0:20:23.360,0:20:28.240 +so this really opens the window to many + +0:20:25.840,0:20:31.120 +many new possibilities to extend emacs + +0:20:28.240,0:20:31.120 +using eaf + +0:20:32.720,0:20:37.760 +all right back here we are always + +0:20:36.080,0:20:39.679 +looking for people to join the + +0:20:37.760,0:20:42.720 +development there are many many + +0:20:39.679,0:20:44.640 +more work that needs to be done like + +0:20:42.720,0:20:46.640 +such as testing and debug if there are + +0:20:44.640,0:20:47.760 +more linux distros and window managers + +0:20:46.640,0:20:51.200 +such as i3 + +0:20:47.760,0:20:52.080 +and stuff i mean you can also add new ef + +0:20:51.200,0:20:54.240 +applications + +0:20:52.080,0:20:55.440 +or debug and enhance existing af + +0:20:54.240,0:20:58.000 +applications + +0:20:55.440,0:21:00.240 +or you can port ef to native wayland + +0:20:58.000,0:21:03.840 +which i just discussed with the + +0:21:00.240,0:21:07.919 +the ems whip kit author uh a kill + +0:21:03.840,0:21:10.159 +akira tile and she he told me that like + +0:21:07.919,0:21:11.200 +really like it must really yeah it + +0:21:10.159,0:21:14.320 +doesn't really work + +0:21:11.200,0:21:16.799 +um native villain because it uses + +0:21:14.320,0:21:18.159 +x valence so it doesn't work on the pgdk + +0:21:16.799,0:21:20.559 +port of emacs + +0:21:18.159,0:21:22.080 +so and we also need people to pour ef to + +0:21:20.559,0:21:25.600 +non-free operating systems + +0:21:22.080,0:21:28.480 +including windows and mac os + +0:21:25.600,0:21:30.080 +and that's because like debug is a linux + +0:21:28.480,0:21:31.360 +specific feature so it doesn't really + +0:21:30.080,0:21:33.039 +work on other platform + +0:21:31.360,0:21:34.640 +we need to change replace it with some + +0:21:33.039,0:21:36.720 +alternative and + +0:21:34.640,0:21:38.640 +geographic scene somehow doesn't really + +0:21:36.720,0:21:40.320 +work on mac os + +0:21:38.640,0:21:42.880 +and there are many other to-do lists + +0:21:40.320,0:21:45.039 +available so please have a look + +0:21:42.880,0:21:46.640 +if and see it's anything you want to + +0:21:45.039,0:21:49.039 +work on + +0:21:46.640,0:21:51.120 +all right so since this is a + +0:21:49.039,0:21:53.520 +pre-recorded talk i won't be able to do + +0:21:51.120,0:21:56.080 +the q a real time in the video + +0:21:53.520,0:21:57.200 +however i will be around on the + +0:21:56.080,0:22:00.559 +collaborate pad + +0:21:57.200,0:22:01.360 +and the irc

+0:00:17.520,0:00:19.840 +do we go top to bottom for time + +0:00:19.119,0:00:23.920 +progression + +0:00:19.840,0:00:27.279 +uh and left to right uh for low to high + +0:00:23.920,0:00:30.000 +interesting i think uh so the initial + +0:00:27.279,0:00:31.599 +uh thing i was copying that initial app + +0:00:30.000,0:00:35.280 +work this way + +0:00:31.599,0:00:36.960 +um and + +0:00:35.280,0:00:38.960 +yeah i mean certainly traditional music + +0:00:36.960,0:00:43.040 +you know on a staff uh + +0:00:38.960,0:00:46.000 +does go left to right uh like this + +0:00:43.040,0:00:47.440 +um i mean going top to bottom does make + +0:00:46.000,0:00:48.960 +it easier to add more beats without + +0:00:47.440,0:00:49.920 +having to wrap but certainly that could + +0:00:48.960,0:00:52.239 +be managed + +0:00:49.920,0:00:53.760 +um yeah i i had not really thought about + +0:00:52.239,0:00:55.199 +it but it is definitely something worth + +0:00:53.760,0:00:59.840 +looking into + +0:00:55.199,0:00:59.840 +uh yeah you are now unmuted + +0:01:02.480,0:01:06.960 +ah good point thank you let me go ahead + +0:01:05.680,0:01:13.840 +and do that + +0:01:06.960,0:01:13.840 +uh the entire screen + +0:01:14.240,0:01:18.320 +okay so the screen share should be + +0:01:16.880,0:01:21.439 +starting + +0:01:18.320,0:01:24.880 +there we go cool all right uh + +0:01:21.439,0:01:26.640 +two will be placed on the song um not + +0:01:24.880,0:01:28.080 +now i can i can make some recordings of + +0:01:26.640,0:01:30.720 +it or certainly you can try it + +0:01:28.080,0:01:33.119 +um i couldn't quite get the the + +0:01:30.720,0:01:37.040 +microphone and the webcam and everything + +0:01:33.119,0:01:40.079 +to work with the sound playing now um so + +0:01:37.040,0:01:43.520 +uh i can record some also please uh + +0:01:40.079,0:01:46.640 +i put a link at the uh here in the uh + +0:01:43.520,0:01:48.479 +ether pad uh zck dot me slash emacs conf + +0:01:46.640,0:01:49.920 +2020 where you can go and get the source + +0:01:48.479,0:01:51.920 +and you can try it yourself uh there's + +0:01:49.920,0:01:54.560 +no dependencies needed so it's just all + +0:01:51.920,0:01:56.880 +in emacs um so please you know try it + +0:01:54.560,0:01:56.880 +yourself + +0:01:57.040,0:02:01.040 +any chance for an emacs tracker or mod + +0:02:00.079,0:02:03.680 +player + +0:02:01.040,0:02:04.479 +um i don't really know what a mod player + +0:02:03.680,0:02:08.000 +or tracker + +0:02:04.479,0:02:09.679 +are but i mean i'm sure + +0:02:08.000,0:02:11.599 +that would be cool uh maybe there's one + +0:02:09.679,0:02:13.920 +on now but i don't know uh + +0:02:11.599,0:02:15.200 +my musical background so i've played + +0:02:13.920,0:02:15.840 +various instruments since about the + +0:02:15.200,0:02:18.160 +third grade + +0:02:15.840,0:02:19.520 +uh started recorder uh play cello i play + +0:02:18.160,0:02:22.560 +guitar now + +0:02:19.520,0:02:23.680 +um but yeah so just kind of random + +0:02:22.560,0:02:26.959 +instruments and + +0:02:23.680,0:02:27.280 +uh yeah i guess kind of some of those + +0:02:26.959,0:02:30.480 +things + +0:02:27.280,0:02:33.519 +influence how i think about music um + +0:02:30.480,0:02:35.360 +uh yeah um + +0:02:33.519,0:02:36.640 +are there any open source musical + +0:02:35.360,0:02:37.840 +management sample libraries that could + +0:02:36.640,0:02:41.200 +be used + +0:02:37.840,0:02:42.400 +um good question i'm sure there are um i + +0:02:41.200,0:02:43.360 +don't know any that integrate really + +0:02:42.400,0:02:44.560 +well with emacs + +0:02:43.360,0:02:45.680 +one of the cool things that i liked + +0:02:44.560,0:02:47.440 +about this is that there are no + +0:02:45.680,0:02:49.360 +dependencies + +0:02:47.440,0:02:50.800 +you know you don't need any external + +0:02:49.360,0:02:53.040 +program to + +0:02:50.800,0:02:54.160 +uh generate the music i mean it it does + +0:02:53.040,0:02:57.280 +shell out to + +0:02:54.160,0:02:58.640 +to play um but that + +0:02:57.280,0:02:59.840 +should be able to be done on any + +0:02:58.640,0:03:03.200 +operating system as always you have + +0:02:59.840,0:03:03.200 +something that can play wav files + +0:03:03.519,0:03:06.879 +um but yeah it is interesting to kind of + +0:03:05.599,0:03:10.000 +try the different + +0:03:06.879,0:03:12.239 +uh different sounds and different + +0:03:10.000,0:03:14.400 +tones uh that you could get with + +0:03:12.239,0:03:16.959 +different instruments + +0:03:14.400,0:03:17.599 +have i written any actual songs um + +0:03:16.959,0:03:20.640 +nothing + +0:03:17.599,0:03:20.640 +super uh + +0:03:21.040,0:03:25.519 +uh well put together just i kind of just + +0:03:23.680,0:03:27.440 +been playing around with this + +0:03:25.519,0:03:29.040 +it's kind of i making this was one of + +0:03:27.440,0:03:30.080 +those things where like once i made it i + +0:03:29.040,0:03:31.280 +was like okay + +0:03:30.080,0:03:32.720 +now i can play with it and i did a + +0:03:31.280,0:03:33.920 +little bit and was like i don't know if + +0:03:32.720,0:03:37.280 +i feel like it right now + +0:03:33.920,0:03:38.720 +you know which i've i've found that to + +0:03:37.280,0:03:39.599 +be the case with some things that i've + +0:03:38.720,0:03:41.360 +implemented + +0:03:39.599,0:03:43.519 +in emacs where it's i make it and then + +0:03:41.360,0:03:44.480 +it's the kind of some of the desire to + +0:03:43.519,0:03:46.879 +use it all the time + +0:03:44.480,0:03:47.760 +goes away but i'm sure i'll circle back + +0:03:46.879,0:03:51.040 +around + +0:03:47.760,0:03:52.400 +at some point especially kind of maybe + +0:03:51.040,0:03:54.640 +once i add in different tones or + +0:03:52.400,0:03:56.400 +something + +0:03:54.640,0:03:57.840 +i guess a similar question for + +0:03:56.400,0:04:01.120 +pre-recorded sounds yeah i mean + +0:03:57.840,0:04:02.080 +if it's part of what i did what i wrote + +0:04:01.120,0:04:04.720 +was a + +0:04:02.080,0:04:06.720 +wave generation library so if you kind + +0:04:04.720,0:04:08.400 +of have the data + +0:04:06.720,0:04:10.159 +you could use those and like chop them + +0:04:08.400,0:04:13.360 +up and take certain lengths of them + +0:04:10.159,0:04:14.959 +and make a wav file so it's not plug and + +0:04:13.360,0:04:19.120 +play right now but you could certainly + +0:04:14.959,0:04:21.040 +add those notes uh to do it + +0:04:19.120,0:04:22.720 +um any knitting midi mapping + +0:04:21.040,0:04:24.560 +possibilities um + +0:04:22.720,0:04:26.160 +i haven't looked into it but i'm sure + +0:04:24.560,0:04:28.800 +you definitely could output to midi + +0:04:26.160,0:04:30.400 +um which is another benefit of having + +0:04:28.800,0:04:31.520 +that multiple layers with the top layer + +0:04:30.400,0:04:33.360 +is just like + +0:04:31.520,0:04:35.120 +um you know if the root note is this + +0:04:33.360,0:04:36.560 +we're just two semitones up or seven + +0:04:35.120,0:04:38.160 +semitones up or whatever it is + +0:04:36.560,0:04:40.720 +uh it should be relatively simple to + +0:04:38.160,0:04:44.479 +kind of switch out that layer underneath + +0:04:40.720,0:04:45.759 +uh from wave to midi or other things + +0:04:44.479,0:04:47.520 +what were some of the challenges with + +0:04:45.759,0:04:49.759 +writing a special mode for emacs + +0:04:47.520,0:04:51.040 +uh interested in getting into this not + +0:04:49.759,0:04:54.960 +sure where to start + +0:04:51.040,0:04:57.120 +um there uh yeah it so + +0:04:54.960,0:04:58.320 +this isn't the first mode i've written + +0:04:57.120,0:05:01.759 +um so that's right + +0:04:58.320,0:05:05.600 +certainly that helps um i actually + +0:05:01.759,0:05:08.240 +um i have a video that we recorded it + +0:05:05.600,0:05:09.039 +as part of emacs nyc on making a major + +0:05:08.240,0:05:10.720 +mode + +0:05:09.039,0:05:12.639 +that's basically like starts from + +0:05:10.720,0:05:15.680 +nothing and kind of builds up to + +0:05:12.639,0:05:17.039 +an implementation of tic-tac-toe um + +0:05:15.680,0:05:19.600 +but so it kind of goes into printing + +0:05:17.039,0:05:21.280 +things out and buttons and making the + +0:05:19.600,0:05:22.800 +mode + +0:05:21.280,0:05:24.560 +i mean one of the best parts about emacs + +0:05:22.800,0:05:26.479 +is because it's so + +0:05:24.560,0:05:28.479 +uh configurable and so introspectible + +0:05:26.479,0:05:30.320 +you can start pretty simply + +0:05:28.479,0:05:32.320 +and just kind of asking max about things + +0:05:30.320,0:05:34.960 +and then make one little + +0:05:32.320,0:05:36.479 +change um it's really it's not that bad + +0:05:34.960,0:05:39.039 +so uh + +0:05:36.479,0:05:40.560 +i'll try to throw a link up on that uh + +0:05:39.039,0:05:42.000 +on on that page i put up or + +0:05:40.560,0:05:44.479 +please email me for whoever asked this + +0:05:42.000,0:05:46.240 +question uh to get a link to that video + +0:05:44.479,0:05:47.919 +um or just look at look at the source + +0:05:46.240,0:05:50.479 +code of this or any other major mode + +0:05:47.919,0:05:52.880 +um it it's pretty ems breaks it makes it + +0:05:50.479,0:05:56.479 +pretty easy to extend uh + +0:05:52.880,0:05:57.600 +major modes and i think that's that's + +0:05:56.479,0:06:00.240 +the last question + +0:05:57.600,0:06:02.479 +in the ether pad so uh thanks so much + +0:06:00.240,0:06:06.720 +everybody for coming +

messenger + +0:00:33.200,0:00:37.120 +he says that we have good progress and + +0:00:35.840,0:00:39.040 +support for cairo + +0:00:37.120,0:00:40.320 +this is going to be enabled by default + +0:00:39.040,0:00:42.480 +and emax 28 + +0:00:40.320,0:00:44.800 +and cairo plus half buzz is going to be + +0:00:42.480,0:00:46.879 +the preferred rendering combination + +0:00:44.800,0:00:48.719 +so cairo support is not new but in the + +0:00:46.879,0:00:51.440 +past there were a lot of bugs in the + +0:00:48.719,0:00:52.960 +code and so it was made experimental + +0:00:51.440,0:00:54.960 +so most of those bugs have been fixed + +0:00:52.960,0:00:56.320 +recently and now it becomes the default + +0:00:54.960,0:00:58.320 +and the next major version + +0:00:56.320,0:01:00.320 +which will enable several good features + +0:00:58.320,0:01:01.680 +such as color emojis if you're looking + +0:01:00.320,0:01:04.720 +forward to those + +0:01:01.680,0:01:06.560 +xft as a result is deprecated there are + +0:01:04.720,0:01:07.760 +bugs not getting fixed in that code it + +0:01:06.560,0:01:08.720 +doesn't appear to be very well + +0:01:07.760,0:01:10.960 +maintained + +0:01:08.720,0:01:13.760 +it was the most advanced font mac end + +0:01:10.960,0:01:15.920 +and emax before cairo became dependable + +0:01:13.760,0:01:17.840 +so now that we have a more a better +

+0:01:23.200,0:01:26.400 +in lisp + +0:01:23.840,0:01:28.080 +will also be landing soon it's currently + +0:01:26.400,0:01:28.799 +on a branch but there are several people + +0:01:28.080,0:01:31.040 +using it + +0:01:28.799,0:01:32.479 +they say they're very impressed it does + +0:01:31.040,0:01:35.600 +require live gcc + +0:01:32.479,0:01:37.439 +jit to be installed for it to work and + +0:01:35.600,0:01:38.960 +this means you have to have gcc 10 + +0:01:37.439,0:01:41.040 +installed + +0:01:38.960,0:01:42.240 +execution of emacs lisp with native + +0:01:41.040,0:01:45.280 +compilation on + +0:01:42.240,0:01:46.159 +is about 2.5 times faster than the + +0:01:45.280,0:01:48.399 +bytecode + +0:01:46.159,0:01:49.439 +interpreter we don't yet have any +

having more + +0:01:54.720,0:01:58.320 +numbers and analysis to see what the + +0:01:56.399,0:02:01.360 +real impact of that is going to be + +0:01:58.320,0:02:02.799 +also it may vary in compute advantage + +0:02:01.360,0:02:04.320 +based on the type of workload that + +0:02:02.799,0:02:06.240 +you're performing + +0:02:04.320,0:02:08.080 +a downside to the native compilation at + +0:02:06.240,0:02:10.720 +the moment is that it takes a long + +0:02:08.080,0:02:12.720 +time to compile even when you're doing a + +0:02:10.720,0:02:14.959 +16 core build of emacs + +0:02:12.720,0:02:15.760 +it can still take 15 minutes to compile + +0:02:14.959,0:02:17.840 +emacs + +0:02:15.760,0:02:19.520 +and all of its in all of its lisp code + +0:02:17.840,0:02:21.840 +with this enabled + +0:02:19.520,0:02:23.120 +also this is going to have to happen on + +0:02:21.840,0:02:25.360 +every user's machine + +0:02:23.120,0:02:27.520 +because we cannot distribute the native + +0:02:25.360,0:02:28.319 +compilation products they are specific + +0:02:27.520,0:02:29.760 +to the compo + +0:02:28.319,0:02:31.440 +to the processor that you might be + +0:02:29.760,0:02:33.920 +running on so + +0:02:31.440,0:02:35.680 +the emax distribution will remain much + +0:02:33.920,0:02:37.760 +as it is now but if you want to have the + +0:02:35.680,0:02:39.599 +benefits of natively compiled + +0:02:37.760,0:02:41.519 +core lisp files you're going to have to + +0:02:39.599,0:02:42.400 +spend that time and have gcc 10 + +0:02:41.519,0:02:45.840 +available + +0:02:42.400,0:02:48.959 +to get that compilation support um + +0:02:45.840,0:02:52.160 +the gtk only build is being prepared + +0:02:48.959,0:02:52.959 +for merging so what this does is it + +0:02:52.160,0:02:55.120 +throws away + +0:02:52.959,0:02:56.000 +most of the other tool kits that emacs + +0:02:55.120,0:02:59.280 +was using + +0:02:56.000,0:03:01.760 +and relies only on gtk making emacs + +0:02:59.280,0:03:03.920 +much more of a gtk application than it + +0:03:01.760,0:03:06.480 +has been + +0:03:03.920,0:03:08.480 +the main issue here is that we were + +0:03:06.480,0:03:09.360 +abusing gtk in some ways that weren't + +0:03:08.480,0:03:10.879 +really meant + +0:03:09.360,0:03:12.879 +and now we're going to be more of a + +0:03:10.879,0:03:14.080 +first club gtk will be more of a first + +0:03:12.879,0:03:17.040 +class citizen in the + +0:03:14.080,0:03:17.440 +approach and the ways that we use it and + +0:03:17.040,0:03:19.280 +and + +0:03:17.440,0:03:21.200 +be using it in the ways that the gtk + +0:03:19.280,0:03:23.360 +developers intended + +0:03:21.200,0:03:24.640 +there is going to be much more support + +0:03:23.360,0:03:27.280 +for xt mouse + +0:03:24.640,0:03:29.120 +so xt mouse allows you to use your mouse + +0:03:27.280,0:03:30.799 +inside of a terminal window + +0:03:29.120,0:03:33.120 +which you could do before but there were + +0:03:30.799,0:03:36.159 +certain aspects such as menus + +0:03:33.120,0:03:38.239 +that weren't supported so instead of + +0:03:36.159,0:03:39.840 +having kind of partial support for mouse + +0:03:38.239,0:03:42.879 +inside of an x term with xt + +0:03:39.840,0:03:44.959 +mouse you get full support this is going + +0:03:42.879,0:03:46.720 +to allow + +0:03:44.959,0:03:48.159 +changes in the way that things can be + +0:03:46.720,0:03:51.200 +bound the ways that + +0:03:48.159,0:03:53.200 +uh key bindings can the mouse events can + +0:03:51.200,0:03:56.879 +be mapped to key bindings while in + +0:03:53.200,0:03:58.480 +x terms and um yeah little by little + +0:03:56.879,0:03:59.040 +this support is being extended even + +0:03:58.480,0:04:01.599 +further + +0:03:59.040,0:04:04.080 +so we look forward to seeing that + +0:04:01.599,0:04:06.239 +develop in the near term + +0:04:04.080,0:04:08.080 +once this is merged by the way also then + +0:04:06.239,0:04:09.840 +emacs will have mouse support in every + +0:04:08.080,0:04:12.720 +one of its available configurations + +0:04:09.840,0:04:14.680 +which has not been true until now emacs + +0:04:12.720,0:04:17.519 +27 will be soon releasing + +0:04:14.680,0:04:19.919 +27.2 and the pretest for that should + +0:04:17.519,0:04:20.880 +begin sometime soon after emacs comp is + +0:04:19.919,0:04:23.360 +done + +0:04:20.880,0:04:24.800 +and finally emacs 28 is going to get + +0:04:23.360,0:04:26.479 +better emoji support + +0:04:24.800,0:04:29.120 +right now emojis are registered + +0:04:26.479,0:04:31.759 +internally within emacs as symbols + +0:04:29.120,0:04:33.759 +which works in some ways but does not + +0:04:31.759,0:04:37.360 +support some of the special features + +0:04:33.759,0:04:40.000 +of of emojis such as different + +0:04:37.360,0:04:41.120 +skin tones for the hand emoji or face + +0:04:40.000,0:04:43.280 +emojis + +0:04:41.120,0:04:45.199 +in emacs 28 emojis are going to have + +0:04:43.280,0:04:47.199 +their own support within the sequel + +0:04:45.199,0:04:49.360 +c code and then this is going to allow + +0:04:47.199,0:04:52.720 +those types of variations and other + +0:04:49.360,0:04:54.639 +emoji specific font setups so that is + +0:04:52.720,0:04:56.720 +everything for emacs + +0:04:54.639,0:04:59.120 +in the future i don't have a timeline + +0:04:56.720,0:05:01.520 +for you on when 28 will be available + +0:04:59.120,0:05:02.720 +but 27 is going to keep improving until + +0:05:01.520,0:05:04.479 +we're ready to get there +

+0:01:15.040,0:01:19.920 +could do about it + +0:01:16.560,0:01:22.960 +that so many users packages were using + +0:01:19.920,0:01:24.240 +swl and thus essentially using that + +0:01:22.960,0:01:28.080 +definition + +0:01:24.240,0:01:31.360 +of the s dash star symbols + +0:01:28.080,0:01:34.720 +that any attempt to use them + +0:01:31.360,0:01:38.079 +publicly or privately for anything else + +0:01:34.720,0:01:41.680 +would lead to horrible problems + +0:01:38.079,0:01:45.520 +and i don't like that + +0:01:41.680,0:01:49.040 +i decided i wanted to do something + +0:01:45.520,0:01:52.320 +a so that that wouldn't happen again + +0:01:49.040,0:01:55.119 +and b to make it unhappen + +0:01:52.320,0:01:57.840 +in that case well the way to make it + +0:01:55.119,0:02:02.240 +unhappen in that case is with a new + +0:01:57.840,0:02:05.360 +symbol renaming feature the idea is + +0:02:02.240,0:02:09.119 +you rename that file to something else + +0:02:05.360,0:02:11.520 +and then you define an s.e.l that + +0:02:09.119,0:02:13.040 +sets up symbol renaming and then loads + +0:02:11.520,0:02:16.080 +the something else + +0:02:13.040,0:02:16.400 +so it actually runs the same code it + +0:02:16.080,0:02:20.879 +just + +0:02:16.400,0:02:23.920 +doesn't globally define the symbols + +0:02:20.879,0:02:26.160 +s dash whatever but they + +0:02:23.920,0:02:28.319 +appear to work for the programs that + +0:02:26.160,0:02:32.640 +explicitly + +0:02:28.319,0:02:36.000 +require that require sdl + +0:02:32.640,0:02:38.080 +or the s package so this gets the same + +0:02:36.000,0:02:40.239 +behavior for all the programs that are + +0:02:38.080,0:02:43.360 +using that library + +0:02:40.239,0:02:47.840 +and uh doesn't interfere + +0:02:43.360,0:02:50.319 +with the global name space at all + +0:02:47.840,0:02:52.080 +however to do that we need to have a + +0:02:50.319,0:02:55.360 +package + +0:02:52.080,0:02:57.760 +s.e.l that isn't the same + +0:02:55.360,0:02:58.640 +totally a short file that's totally + +0:02:57.760,0:03:01.440 +different + +0:02:58.640,0:03:02.840 +plus we've got to have the file that + +0:03:01.440,0:03:06.239 +normally is called + +0:03:02.840,0:03:10.319 +s.e.l available but + +0:03:06.239,0:03:13.040 +uh under another name well + +0:03:10.319,0:03:14.800 +how are we going to do that we can't put + +0:03:13.040,0:03:18.879 +this into + +0:03:14.800,0:03:21.920 +into emacs in a nice way that + +0:03:18.879,0:03:24.560 +won't make the uh won't make the + +0:03:21.920,0:03:26.480 +maintainer angry + +0:03:24.560,0:03:28.159 +of the mate to the developer of that + +0:03:26.480,0:03:32.080 +package + +0:03:28.159,0:03:34.640 +but we can do it with non-gnu + +0:03:32.080,0:03:36.239 +elpa we can put those two things into + +0:03:34.640,0:03:38.720 +non-gnu elpa + +0:03:36.239,0:03:40.720 +without any difficulty and this shows + +0:03:38.720,0:03:43.280 +one of the advantages + +0:03:40.720,0:03:45.440 +we can put files we can put packages + +0:03:43.280,0:03:48.400 +into non-gdu elpa + +0:03:45.440,0:03:49.599 +and make changes in them now in general + +0:03:48.400,0:03:51.760 +we wouldn't + +0:03:49.599,0:03:54.319 +go to the effort of making big changes + +0:03:51.760,0:03:56.400 +that's just too much to do + +0:03:54.319,0:03:58.000 +unless something's really important but + +0:03:56.400,0:04:01.120 +small changes + +0:03:58.000,0:04:04.319 +that help things fit in are + +0:04:01.120,0:04:07.120 +easy to do and + +0:04:04.319,0:04:10.319 +uh okay oh so basically the recording + +0:04:07.120,0:04:13.439 +didn't get anything until now i just saw + +0:04:10.319,0:04:14.319 +a note pop up this session is now being + +0:04:13.439,0:04:16.320 +recorded + +0:04:14.319,0:04:18.160 +i hope it's been recorded all along it + +0:04:16.320,0:04:21.280 +would be a shame to + +0:04:18.160,0:04:27.120 +spoil oh good okay + +0:04:21.280,0:04:30.479 +okay good so uh that's one of the issues + +0:04:27.120,0:04:33.840 +uh does non-gnu eopa already exist + +0:04:30.479,0:04:35.360 +or is this a sort of quote plan i don't + +0:04:33.840,0:04:37.919 +know why you have to + +0:04:35.360,0:04:40.400 +put scare quotes around the word plan + +0:04:37.919,0:04:44.160 +it's sort of in between + +0:04:40.400,0:04:45.440 +it's the creation of it is started you + +0:04:44.160,0:04:48.160 +will find + +0:04:45.440,0:04:51.520 +that there is an archive that it's + +0:04:48.160,0:04:54.880 +possible to download packages from + +0:04:51.520,0:04:57.120 +and there is a repository to put them in + +0:04:54.880,0:04:58.560 +but that's not the way it's really + +0:04:57.120,0:05:02.800 +supposed to work + +0:04:58.560,0:05:04.320 +uh this is not supposed to be like the + +0:05:02.800,0:05:07.280 +new elpa where there's + +0:05:04.320,0:05:09.039 +one repo for all the packages and thus + +0:05:07.280,0:05:11.199 +anyone who wants to edit any of them + +0:05:09.039,0:05:11.680 +anyone that we want to have edit any of + +0:05:11.199,0:05:13.280 +them + +0:05:11.680,0:05:15.440 +has got to have access to the whole + +0:05:13.280,0:05:18.560 +thing for one thing + +0:05:15.440,0:05:21.840 +some packages will make + +0:05:18.560,0:05:25.120 +an arrangement with the developers + +0:05:21.840,0:05:27.039 +and they'll assure us that they will + +0:05:25.120,0:05:28.400 +do things as things should be done and + +0:05:27.039,0:05:32.080 +then we'll + +0:05:28.400,0:05:35.919 +have their repo copied automatically + +0:05:32.080,0:05:38.160 +or in other cases say + +0:05:35.919,0:05:40.160 +copied manually with a little checking + +0:05:38.160,0:05:43.199 +every so often + +0:05:40.160,0:05:46.400 +uh and then uh in + +0:05:43.199,0:05:49.440 +other cases we'll need to have our own + +0:05:46.400,0:05:52.479 +repo for a particular package + +0:05:49.440,0:05:54.400 +but we shouldn't have a single repo for + +0:05:52.479,0:05:55.919 +all the packages we should have a repo + +0:05:54.400,0:05:57.840 +for each package + +0:05:55.919,0:06:01.120 +so that the people working on that can + +0:05:57.840,0:06:04.319 +get access to modify it + +0:06:01.120,0:06:06.080 +this has to be finished setting up + +0:06:04.319,0:06:07.680 +and we're still working out the + +0:06:06.080,0:06:11.039 +procedures + +0:06:07.680,0:06:14.400 +for instance for making the arrangements + +0:06:11.039,0:06:15.440 +with the developers of a package so that + +0:06:14.400,0:06:18.840 +we can + +0:06:15.440,0:06:20.400 +we hope uh entrust its development to + +0:06:18.840,0:06:24.240 +them and + +0:06:20.400,0:06:24.240 +rely on them directly + +0:06:24.800,0:06:29.520 +and there may be more that needs to be + +0:06:26.560,0:06:29.520 +worked on + +0:06:29.840,0:06:35.840 +oh there's so many questions + +0:06:36.639,0:06:40.880 +well i hope you the third question is + +0:06:39.280,0:06:43.680 +what are the benefits + +0:06:40.880,0:06:46.240 +i hope that people now see the benefits + +0:06:43.680,0:06:49.599 +i've described them + +0:06:46.240,0:06:51.440 +uh next question is it possible to work + +0:06:49.599,0:06:54.720 +with the melba team + +0:06:51.440,0:06:59.440 +to integrate that into emacs + +0:06:54.720,0:07:03.759 +no because the goal doesn't make sense + +0:06:59.440,0:07:07.199 +melba the way it's done does not belong + +0:07:03.759,0:07:08.560 +inside emacs in any sense well first of + +0:07:07.199,0:07:11.280 +all it can't literally be + +0:07:08.560,0:07:13.280 +inside emacs we don't have copyright + +0:07:11.280,0:07:18.160 +assignments for that code + +0:07:13.280,0:07:20.560 +and to get it would be unfeasible + +0:07:18.160,0:07:21.520 +but we're not asking for copyright + +0:07:20.560,0:07:25.280 +assignments for + +0:07:21.520,0:07:27.599 +non-gnu elpa so that's + +0:07:25.280,0:07:31.440 +you might wonder could melpa be merged + +0:07:27.599,0:07:35.039 +with non-venue elpa the problem is + +0:07:31.440,0:07:38.240 +melpa doesn't modify the packages + +0:07:35.039,0:07:41.360 +it's just a place to find releases of + +0:07:38.240,0:07:44.800 +packages wherever they happen to be + +0:07:41.360,0:07:48.319 +and they put packages in with + +0:07:44.800,0:07:51.520 +only a little bit of checking + +0:07:48.319,0:07:51.919 +so no we there are a lot of packages + +0:07:51.520,0:07:55.280 +that are + +0:07:51.919,0:07:58.479 +in melpa that we'd like to get into + +0:07:55.280,0:08:00.800 +non-canoe elpa i don't know the names of + +0:07:58.479,0:08:04.160 +most of them but i expect most of them + +0:08:00.800,0:08:07.680 +would be fine to have but they've got to + +0:08:04.160,0:08:07.680 +be looked at one by one + +0:08:08.560,0:08:14.479 +there are some rules for non-glpa + +0:08:12.000,0:08:18.000 +and the only way to check them is to + +0:08:14.479,0:08:22.160 +check them on one package at a time + +0:08:18.000,0:08:25.039 +and that's going to take effort + +0:08:22.160,0:08:26.080 +now with the people who work on melba + +0:08:25.039,0:08:29.440 +want to get involved + +0:08:26.080,0:08:32.800 +of this that would be great + +0:08:29.440,0:08:33.919 +i haven't tried asking them first we've + +0:08:32.800,0:08:37.599 +got to get this thing + +0:08:33.919,0:08:40.479 +set up i doubt they would want to + +0:08:37.599,0:08:42.959 +but if they said yes that would be + +0:08:40.479,0:08:42.959 +wonderful + +0:08:44.159,0:08:55.839 +uh any thoughts of packages being + +0:08:48.399,0:08:55.839 +added i'm afraid + +0:09:00.959,0:09:03.360 +um + +0:09:05.440,0:09:08.959 +i'm afraid any thoughts of packages + +0:09:07.200,0:09:11.040 +being added as + +0:09:08.959,0:09:13.120 +some url i don't know anything about but + +0:09:11.040,0:09:16.800 +it talks about open source + +0:09:13.120,0:09:17.680 +which means i'm very unlikely to have + +0:09:16.800,0:09:20.959 +much + +0:09:17.680,0:09:24.080 +in common with whatever they say about + +0:09:20.959,0:09:27.760 +either licensing or + +0:09:24.080,0:09:29.959 +what's right and wrong uh + +0:09:27.760,0:09:31.920 +but this seems to be something about + +0:09:29.959,0:09:35.680 +disregarding licenses + +0:09:31.920,0:09:39.360 +altogether well that is basically + +0:09:35.680,0:09:43.360 +asking to lose there are reasons + +0:09:39.360,0:09:45.600 +why we developed gnu licenses to release + +0:09:43.360,0:09:48.320 +software why we have criteria + +0:09:45.600,0:09:49.519 +for which licenses make a program free + +0:09:48.320,0:09:52.640 +software + +0:09:49.519,0:09:55.519 +if the program doesn't carry a license + +0:09:52.640,0:09:56.080 +or if it carries a non-free license that + +0:09:55.519,0:09:59.760 +program + +0:09:56.080,0:10:02.839 +is not free software now you can + +0:09:59.760,0:10:04.800 +maybe get away with disregarding that + +0:10:02.839,0:10:07.600 +fact uh unless + +0:10:04.800,0:10:08.959 +somebody an author or publisher stops + +0:10:07.600,0:10:11.360 +you + +0:10:08.959,0:10:12.399 +but we're not going to take we're not + +0:10:11.360,0:10:15.200 +basically going to + +0:10:12.399,0:10:16.399 +disregard the question of whether the + +0:10:15.200,0:10:19.040 +software we + +0:10:16.399,0:10:21.360 +recommend to people really is free + +0:10:19.040,0:10:24.560 +software or not + +0:10:21.360,0:10:27.519 +that's basically uh + +0:10:24.560,0:10:29.120 +blindfolding yourself to the legal + +0:10:27.519,0:10:30.480 +situation of the software you're + +0:10:29.120,0:10:33.519 +distributing + +0:10:30.480,0:10:35.920 +it's a terrible idea uh if they + +0:10:33.519,0:10:38.640 +disregard our licenses they will hear + +0:10:35.920,0:10:40.959 +from us about it + +0:10:38.640,0:10:42.720 +and if you want to contribute to the + +0:10:40.959,0:10:46.320 +free world + +0:10:42.720,0:10:48.640 +put free licenses on your code + +0:10:46.320,0:10:50.000 +and choose good ones to get this + +0:10:48.640,0:10:53.440 +information + +0:10:50.000,0:10:57.120 +look at gnu.org slash licensing + +0:10:53.440,0:10:59.839 +in particular slash licenses + +0:10:57.120,0:11:01.120 +and one page that input that's important + +0:10:59.839,0:11:05.040 +is license + +0:11:01.120,0:11:07.360 +dash recommendations.html + +0:11:05.040,0:11:09.279 +that's where we advise you on what + +0:11:07.360,0:11:11.360 +license we would recommend you use + +0:11:09.279,0:11:15.600 +depending on the circumstances + +0:11:11.360,0:11:20.160 +there's also license dash list dot html + +0:11:15.600,0:11:22.160 +which describes a lot of licenses and + +0:11:20.160,0:11:25.040 +says which ones are free + +0:11:22.160,0:11:26.160 +which ones are compatible with the new + +0:11:25.040,0:11:28.640 +gpl + +0:11:26.160,0:11:31.519 +it's really important to use only gpl + +0:11:28.640,0:11:34.320 +compatible licenses + +0:11:31.519,0:11:35.519 +so that the various programs can be + +0:11:34.320,0:11:40.480 +combined together + +0:11:35.519,0:11:40.480 +or linked and + +0:11:40.720,0:11:44.240 +you can also get other information about + +0:11:43.120,0:11:47.040 +gnu licenses + +0:11:44.240,0:11:49.680 +and the reasons why they are written the + +0:11:47.040,0:11:49.680 +way they are + +0:11:55.279,0:11:59.760 +oh sorry i don't see the next question + +0:12:03.200,0:12:07.519 +oh why do i insist on using per and + +0:12:05.600,0:12:11.680 +purrs + +0:12:07.519,0:12:14.959 +uh i'm not happy with using + +0:12:11.680,0:12:17.440 +they which is a plural pronoun with a + +0:12:14.959,0:12:20.480 +singular antecedent + +0:12:17.440,0:12:24.800 +it's bad because it causes + +0:12:20.480,0:12:28.639 +confusion that is completely gratuitous + +0:12:24.800,0:12:33.200 +many sentences become a lot of work + +0:12:28.639,0:12:36.480 +to parse and understand if you + +0:12:33.200,0:12:39.839 +add that ambiguity that source of him of + +0:12:36.480,0:12:42.720 +regular ambiguity now +

to convince me but + +0:12:50.800,0:12:55.440 +no one is entitled to give me orders + +0:12:54.240,0:12:58.880 +about that + +0:12:55.440,0:13:03.200 +or state their desires and expect +

we will speak and how we won't speak + +0:13:13.200,0:13:22.880 +now i've spelled out all of these points + +0:13:18.000,0:13:26.079 +in a file called stolman.org + +0:13:22.880,0:13:26.079 +articles

+i will pay attention to them i'll + +0:14:14.000,0:14:18.399 +think about them assuming that they're + +0:14:16.639,0:14:24.079 +not something i've already + +0:14:18.399,0:14:27.760 +considered and

wrong + +0:15:00.720,0:15:05.680 +when you wrote that you could add a + +0:15:02.560,0:15:07.120 +package to non your new elpa + +0:15:05.680,0:15:09.199 +are you implying that you would add +

+0:15:31.680,0:15:38.320 +i have been unable to understand + +0:15:35.040,0:15:42.560 +how there came to be an idea + +0:15:38.320,0:15:45.600 +that those who redistribute packages + +0:15:42.560,0:15:49.360 +have some idea to be mere + +0:15:45.600,0:15:54.480 +some obligation to be near mirrors + +0:15:49.360,0:15:58.560 +and not modify things themselves + +0:15:54.480,0:16:01.440 +well if a package is + +0:15:58.560,0:16:03.440 +being maintained by developers who are + +0:16:01.440,0:16:06.240 +cooperating with us + +0:16:03.440,0:16:07.360 +we'll normally just leave it to them + +0:16:06.240,0:16:10.079 +after all + +0:16:07.360,0:16:10.399 +we have lots of other work to do they + +0:16:10.079,0:16:14.000 +are + +0:16:10.399,0:16:15.600 +clearly experts on the packages they've + +0:16:14.000,0:16:18.399 +developed + +0:16:15.600,0:16:22.800 +let's leave it to them if they make that + +0:16:18.399,0:16:26.480 +sort of arrangement with us but + +0:16:22.800,0:16:29.120 +that's up to them we can't insist that + +0:16:26.480,0:16:30.720 +anyone make an arrangement with us + +0:16:29.120,0:16:33.279 +but since those programs are free +

or vim or + +0:16:45.519,0:16:51.839 +evil mode no + +0:16:52.079,0:16:56.800 +are there any plans to implement + +0:16:53.920,0:17:00.720 +security considerations in non-gnu + +0:16:56.800,0:17:02.959 +elpa uh we probably + +0:17:00.720,0:17:04.959 +should and this will have to be + +0:17:02.959,0:17:08.559 +implemented + +0:17:04.959,0:17:12.000 +but at the moment + +0:17:08.559,0:17:13.280 +developer emacs maintainers will copy + +0:17:12.000,0:17:18.160 +packages + +0:17:13.280,0:17:20.160 +into it and so as long as they are + +0:17:18.160,0:17:22.480 +verifying the packages and getting the + +0:17:20.160,0:17:25.199 +packages from the right place + +0:17:22.480,0:17:25.919 +that will take care of the security once + +0:17:25.199,0:17:30.160 +there is + +0:17:25.919,0:17:33.200 +when with automatic copying in + +0:17:30.160,0:17:35.200 +will have to do something to + +0:17:33.200,0:17:38.480 +make sure that we're fetching the + +0:17:35.200,0:17:38.480 +packages securely + +0:17:40.320,0:17:44.000 +and uh some of you might be interested + +0:17:43.360,0:17:46.080 +in + +0:17:44.000,0:17:48.000 +helping to design and implement this + +0:17:46.080,0:17:52.559 +system + +0:17:48.000,0:17:56.720 +uh what distro do i use + +0:17:52.559,0:17:58.000 +uh well which distro of gnu slash linux + +0:17:56.720,0:18:01.840 +do i use + +0:17:58.000,0:18:01.840 +i use tree scale + +0:18:03.520,0:18:10.080 +i haven't tried most of the free distros + +0:18:07.200,0:18:11.120 +and the reason is it's not crucial that + +0:18:10.080,0:18:13.520 +i do so + +0:18:11.120,0:18:14.799 +we don't need me to rate the various + +0:18:13.520,0:18:17.520 +free distros on + +0:18:14.799,0:18:20.000 +practical questions because anyone can + +0:18:17.520,0:18:24.400 +do that as well as i can + +0:18:20.000,0:18:27.760 +and so you can tell people what + +0:18:24.400,0:18:29.360 +you think of using them for me what's + +0:18:27.760,0:18:32.400 +important to me + +0:18:29.360,0:18:34.160 +is to inform people of the difference + +0:18:32.400,0:18:36.799 +between the free distros + +0:18:34.160,0:18:38.799 +and the non-free distros making sure + +0:18:36.799,0:18:42.000 +people are aware that if you + +0:18:38.799,0:18:45.600 +install a non-free gnu slash linux + +0:18:42.000,0:18:46.720 +distro you'll get a free operating + +0:18:45.600,0:18:49.919 +system with + +0:18:46.720,0:18:54.160 +non-free stuff in various quantities + +0:18:49.919,0:18:56.240 +added thus you will not reach freedom + +0:18:54.160,0:18:57.520 +although you you'll make a lot of + +0:18:56.240,0:19:01.039 +progress compared + +0:18:57.520,0:19:03.919 +with using for instance windows or + +0:19:01.039,0:19:06.160 +mac os or whatever vicious thing it + +0:19:03.919,0:19:08.559 +might be + +0:19:06.160,0:19:09.760 +i'd like to i'd like to people to be + +0:19:08.559,0:19:12.799 +aware + +0:19:09.760,0:19:14.720 +of this next step towards + +0:19:12.799,0:19:16.160 +getting freedom for yourself and your + +0:19:14.720,0:19:24.480 +own computing + +0:19:16.160,0:19:26.799 +so that you can do that if you want to + +0:19:24.480,0:19:26.799 +uh + +0:19:29.039,0:19:32.799 +so who gets to make the final decision + +0:19:31.360,0:19:36.640 +regarding + +0:19:32.799,0:19:39.200 +non-gnu elpa the + +0:19:36.640,0:19:40.960 +emax maintainers are going to be in + +0:19:39.200,0:19:44.480 +charge of this + +0:19:40.960,0:19:47.760 +but because it's not + +0:19:44.480,0:19:51.360 +just a technical decision it has with + +0:19:47.760,0:19:54.960 +only technical consequences + +0:19:51.360,0:19:57.760 +but in general unless there's some + +0:19:54.960,0:20:00.720 +severe problem with the package we will + +0:19:57.760,0:20:00.720 +want to put it in + +0:20:03.600,0:20:07.440 +and i expect most packages won't have a + +0:20:06.400,0:20:09.919 +problem + +0:20:07.440,0:20:11.679 +and we can just put them in when we get + +0:20:09.919,0:20:15.919 +to them + +0:20:11.679,0:20:17.600 +won't the elpa link to non-free sites + +0:20:15.919,0:20:20.799 +like github + +0:20:17.600,0:20:24.320 +uh it's a mistake to talk about a + +0:20:20.799,0:20:24.320 +non-free site + +0:20:25.760,0:20:32.159 +because a site is not a program + +0:20:29.120,0:20:32.960 +a program is either free or non-free and + +0:20:32.159,0:20:36.480 +we have + +0:20:32.960,0:20:39.679 +clearly stated criteria for that in + +0:20:36.480,0:20:43.039 +gnu.org philosophy slash + +0:20:39.679,0:20:45.360 +free dash sw.html we have the free + +0:20:43.039,0:20:51.360 +software definition + +0:20:45.360,0:20:51.360 +but a site well their programs on it + +0:20:51.919,0:20:55.120 +but it doesn't make sense to ask whether + +0:20:54.000,0:20:58.000 +the site is + +0:20:55.120,0:20:58.880 +free or not it's too simplistic a + +0:20:58.000,0:21:02.000 +question + +0:20:58.880,0:21:05.679 +to have a meaningful answer now one + +0:21:02.000,0:21:08.799 +thing you can ask about is does the site + +0:21:05.679,0:21:11.760 +send javascript to the user's machine + +0:21:08.799,0:21:12.960 +to the user's browser and if so is that + +0:21:11.760,0:21:17.120 +javascript + +0:21:12.960,0:21:19.919 +non-free well github + +0:21:17.120,0:21:21.200 +does send non-free javascript for some + +0:21:19.919,0:21:24.240 +operations + +0:21:21.200,0:21:26.159 +so we consider it unsatisfactory as a + +0:21:24.240,0:21:29.600 +repository + +0:21:26.159,0:21:33.360 +but uh that doesn't mean linking to it + +0:21:29.600,0:21:34.720 +for is a bad thing to do regardless of + +0:21:33.360,0:21:36.640 +what the purpose is + +0:21:34.720,0:21:38.240 +for instance if the purpose is to refer + +0:21:36.640,0:21:40.799 +to some things + +0:21:38.240,0:21:42.880 +that you can access without running the + +0:21:40.799,0:21:47.039 +non-free javascript + +0:21:42.880,0:21:47.039 +then it's okay for that purpose + +0:21:47.200,0:21:52.559 +so if now that you understand the + +0:21:50.480,0:21:54.880 +details of this issue + +0:21:52.559,0:21:55.919 +you think that there is a problem with + +0:21:54.880,0:22:00.080 +the + +0:21:55.919,0:22:03.679 +link to camel there's + +0:22:00.080,0:22:06.799 +sorry a link in camel dot html + +0:22:03.679,0:22:10.880 +well report it to + +0:22:06.799,0:22:14.159 +uh bug gnu emax reported as an emacs bug + +0:22:10.880,0:22:15.840 +but do think about the criteria i've + +0:22:14.159,0:22:18.000 +just said because maybe it's not a + +0:22:15.840,0:22:21.840 +problem + +0:22:18.000,0:22:24.559 +is it okay to use the gnu of pharaoh gpl + +0:22:21.840,0:22:27.840 +for emax packages + +0:22:24.559,0:22:27.840 +yes it is + +0:22:28.880,0:22:32.080 +uh which is your favorite programming + +0:22:31.120,0:22:35.200 +language + +0:22:32.080,0:22:38.400 +if lisp which variant + +0:22:35.200,0:22:41.760 +well i don't exactly have a + +0:22:38.400,0:22:45.120 +favorite variant but + +0:22:41.760,0:22:47.520 +when i designed emacs lisp i + +0:22:45.120,0:22:48.799 +did the best thing i could think of at + +0:22:47.520,0:22:52.559 +the time + +0:22:48.799,0:22:55.520 +subject to the need to keep it small + +0:22:52.559,0:22:56.960 +for the first few years it was important + +0:22:55.520,0:22:59.840 +for gdu emacs + +0:22:56.960,0:23:00.799 +to run in a machine which could only + +0:22:59.840,0:23:04.480 +give it half + +0:23:00.799,0:23:06.559 +a meg of user space + +0:23:04.480,0:23:09.200 +so there are a lot of constructs that + +0:23:06.559,0:23:12.320 +clearly were desirable to include + +0:23:09.200,0:23:15.840 +that i left out because we could + +0:23:12.320,0:23:15.840 +make it work without them + +0:23:16.880,0:23:20.640 +and then a lot of those have been added + +0:23:18.960,0:23:23.200 +since because + +0:23:20.640,0:23:37.840 +it's been a long time since we needed to + +0:23:23.200,0:23:37.840 +keep emacs so rigorously small + +0:23:40.960,0:23:47.679 +um someone is + +0:23:44.240,0:23:51.360 +asking about the + +0:23:47.679,0:23:54.400 +fsf's repository project well + +0:23:51.360,0:23:55.440 +we agreed that there would be another + +0:23:54.400,0:23:59.919 +virtual machine + +0:23:55.440,0:24:05.840 +running one of those for the gnu project + +0:23:59.919,0:24:05.840 +but that's as far as the discussion went + +0:24:15.840,0:24:25.600 +question 17 is extremely insulting + +0:24:20.480,0:24:28.720 +i have not engaged in sexual harassment + +0:24:25.600,0:24:28.960 +don't expect me to plead guilty to such + +0:24:28.720,0:24:32.640 +a + +0:24:28.960,0:24:35.600 +nasty claim + +0:24:32.640,0:24:36.799 +people have been accusing me of many + +0:24:35.600,0:24:39.919 +things + +0:24:36.799,0:24:43.120 +some of which are + +0:24:39.919,0:24:46.559 +basically mole hills and some of which + +0:24:43.120,0:24:50.640 +are false so + +0:24:46.559,0:24:53.840 +uh i'm not going to give them + +0:24:50.640,0:24:56.400 +anything i have been bullied in a + +0:24:53.840,0:24:59.360 +horrible way + +0:24:56.400,0:24:59.360 +that was wrong + +0:24:59.679,0:25:03.520 +i would like the bullies to apologize to + +0:25:02.720,0:25:06.320 +me + +0:25:03.520,0:25:08.960 +and when i see that they're not bullying + +0:25:06.320,0:25:11.279 +i will forgive them + +0:25:08.960,0:25:14.799 +i would like to have conversations with + +0:25:11.279,0:25:17.840 +them if any of the mole hills + +0:25:14.799,0:25:20.880 +annoyed someone i'm happy to talk + +0:25:17.840,0:25:29.840 +with her and thus + +0:25:20.880,0:25:29.840 +uh help help resolve things with peace + +0:25:31.120,0:25:39.200 +and my opinion on + +0:25:35.120,0:25:42.720 +quote diversity within + +0:25:39.200,0:25:45.679 +emacs well emacs is + +0:25:42.720,0:25:46.480 +never going to be diverse it is extended + +0:25:45.679,0:25:49.760 +in + +0:25:46.480,0:25:53.279 +one language emacs lisp + +0:25:49.760,0:25:55.840 +well i don't know uh we did have an idea + +0:25:53.279,0:25:58.400 +of implementing extensibility using + +0:25:55.840,0:26:01.120 +scheme and the hope was that guile + +0:25:58.400,0:26:02.960 +could be integrated with emacs that + +0:26:01.120,0:26:05.279 +turned out to be difficult it may be + +0:26:02.960,0:26:07.520 +impossible but in principle + +0:26:05.279,0:26:11.039 +it might be a good thing that would be a + +0:26:07.520,0:26:14.960 +small amount of diversity + +0:26:11.039,0:26:16.960 +but it's not that important + +0:26:14.960,0:26:18.880 +what i think is really important for + +0:26:16.960,0:26:22.799 +developing emacs + +0:26:18.880,0:26:27.039 +is to make it do word processing + +0:26:22.799,0:26:30.080 +i sometimes use libra office + +0:26:27.039,0:26:32.799 +and yeah i can make it do things + +0:26:30.080,0:26:34.880 +it has features for wysiwyg which are + +0:26:32.799,0:26:38.000 +very nice + +0:26:34.880,0:26:40.400 +but it's in other regards + +0:26:38.000,0:26:42.400 +it's not emacs and it doesn't have the + +0:26:40.400,0:26:45.520 +abilities of emacs + +0:26:42.400,0:26:45.520 +and it should + +0:26:45.600,0:26:49.039 +so i urge people to work on extending + +0:26:48.400,0:26:51.600 +emacs + +0:26:49.039,0:27:07.840 +in that direction adding the features + +0:26:51.600,0:27:07.840 +that a word processor has to have + +0:27:13.600,0:27:21.679 +the last question i can answer is + +0:27:16.640,0:27:24.960 +18 but yes it's a very sad thing + +0:27:21.679,0:27:28.399 +how many companies + +0:27:24.960,0:27:33.200 +insist on using non-free software + +0:27:28.399,0:27:36.799 +well i would get a different kind of job + +0:27:33.200,0:27:40.320 +that's a decision i made many years ago + +0:27:36.799,0:27:42.799 +early in the gnu project + +0:27:40.320,0:27:47.440 +i decided i would not first i would not + +0:27:42.799,0:27:47.440 +get a job developing non-free software + +0:27:47.679,0:27:54.880 +and later on i decided + +0:27:50.960,0:27:57.120 +once i could stop using non-free + +0:27:54.880,0:28:00.799 +software that is once we had + +0:27:57.120,0:28:05.679 +a gnu slash linux system that we could + +0:28:00.799,0:28:05.679 +switch over to and uh + +0:28:08.320,0:28:16.240 +oh wait i thought i thought magic wand + +0:28:11.679,0:28:20.080 +time meant it was time to stop + +0:28:16.240,0:28:20.080 +but now i rather ask the question + +0:28:21.039,0:28:23.279 +uh + +0:28:27.760,0:28:35.679 +so what do you do well if i were you + +0:28:32.480,0:28:37.440 +i'd probably not work for any of those + +0:28:35.679,0:28:39.679 +companies + +0:28:37.440,0:28:40.799 +if i needed to make money i'd get a job + +0:28:39.679,0:28:43.840 +but i get some + +0:28:40.799,0:28:48.080 +other kind of job + +0:28:43.840,0:28:51.039 +that didn't involve using software + +0:28:48.080,0:28:53.600 +i would or that let me choose the + +0:28:51.039,0:28:56.880 +software i would use + +0:28:53.600,0:28:58.000 +but i would live cheaply you know the + +0:28:56.880,0:29:00.640 +less you spend + +0:28:58.000,0:29:01.120 +the less you need to make and the more + +0:29:00.640,0:29:04.720 +time + +0:29:01.120,0:29:07.200 +you can take away from your paid work + +0:29:04.720,0:29:08.640 +and the more flexibility you have in + +0:29:07.200,0:29:13.039 +which paid work + +0:29:08.640,0:29:16.399 +you can do being in a position + +0:29:13.039,0:29:19.919 +to say no to avoid being + +0:29:16.399,0:29:19.919 +desperate to say yes + +0:29:23.679,0:29:31.200 +uh strengthens your position + +0:29:27.440,0:29:33.279 +and you need that one way you can help + +0:29:31.200,0:29:36.559 +do that is by + +0:29:33.279,0:29:38.960 +not having children now that is a + +0:29:36.559,0:29:41.760 +tangent but it can't be denied that + +0:29:38.960,0:29:42.399 +raising children is very expensive i + +0:29:41.760,0:29:45.559 +have heard + +0:29:42.399,0:29:48.080 +many people say that they are + +0:29:45.559,0:29:50.880 +uncomfortable with their jobs + +0:29:48.080,0:29:52.240 +but they have to do those jobs to make + +0:29:50.880,0:29:55.440 +enough money + +0:29:52.240,0:29:59.120 +to support their children + +0:29:55.440,0:30:01.520 +well think about that be aware + +0:29:59.120,0:30:04.720 +that's likely to happen to you before + +0:30:01.520,0:30:04.720 +you make that decision + +0:30:06.159,0:30:09.840 +what would i + +0:30:10.000,0:30:16.960 +what would i change about free software + +0:30:13.279,0:30:20.880 +well since this is + +0:30:16.960,0:30:25.600 +magic i would magically find + +0:30:20.880,0:30:28.000 +a way of showing everyone why + +0:30:25.600,0:30:29.679 +most free software needs to be copy + +0:30:28.000,0:30:32.480 +lifted + +0:30:29.679,0:30:34.880 +so that our community would not + +0:30:32.480,0:30:38.640 +basically + +0:30:34.880,0:30:41.360 +submit to abuse by proprietary software + +0:30:38.640,0:30:41.360 +developers + +0:30:45.919,0:30:53.279 +of course i could go further if i could + +0:30:49.760,0:30:55.760 +magically recruit a hundred thousand + +0:30:53.279,0:30:57.919 +good programmers to do lots of work + +0:30:55.760,0:31:01.039 +improving free software + +0:30:57.919,0:31:03.279 +we might well if we could do this 20 + +0:31:01.039,0:31:06.559 +years ago we might have wiped out + +0:31:03.279,0:31:07.200 +non-free systems and then we wouldn't + +0:31:06.559,0:31:10.320 +have had + +0:31:07.200,0:31:14.480 +horrible things like + +0:31:10.320,0:31:18.000 +world wide web drm that + +0:31:14.480,0:31:20.480 +no one has the courage to resist + +0:31:18.000,0:31:22.640 +if they're desperately trying to get + +0:31:20.480,0:31:26.240 +money for anything + +0:31:22.640,0:31:29.519 +and if they need approval of companies + +0:31:26.240,0:31:32.960 +of the big companies that push for drm + +0:31:29.519,0:31:36.720 +uh then they don't dare even resist as + +0:31:32.960,0:31:36.720 +much as they can resist + +0:31:38.240,0:31:43.200 +and look what happened to the world wide + +0:31:40.880,0:31:47.279 +web consortium + +0:31:43.200,0:31:50.399 +uh they surrendered blatantly + +0:31:47.279,0:31:54.399 +and ignominiously by + +0:31:50.399,0:31:54.399 +endorsing the drm system + +0:31:55.760,0:32:00.880 +so what can you do i don't have a magic + +0:31:59.600,0:32:04.720 +wand + +0:32:00.880,0:32:06.559 +i'm a human being with the capabilities + +0:32:04.720,0:32:09.919 +i have + +0:32:06.559,0:32:12.840 +but the advantage of + +0:32:09.919,0:32:14.000 +great firmness in campaigning for free + +0:32:12.840,0:32:18.240 +software + +0:32:14.000,0:32:23.200 +and this enables me to do things + +0:32:18.240,0:32:23.200 +that no one else will do + +0:32:27.679,0:32:31.519 +what tools from pre unix days do you + +0:32:30.480,0:32:34.240 +miss + +0:32:31.519,0:32:34.880 +well i don't i don't think about them + +0:32:34.240,0:32:38.640 +with + +0:32:34.880,0:32:42.080 +missing them actually but + +0:32:38.640,0:32:46.240 +it was sort of nice to have + +0:32:42.080,0:32:49.600 +ddt as your login shell + +0:32:46.240,0:32:52.640 +so in using modern terminology + +0:32:49.600,0:32:55.519 +because that meant at any time you could + +0:32:52.640,0:32:57.519 +stop a program lotus debugging symbols + +0:32:55.519,0:32:58.799 +and start examining the data in the + +0:32:57.519,0:33:01.519 +instructions + +0:32:58.799,0:33:03.039 +you could debug it that way and then you + +0:33:01.519,0:33:06.720 +could even + +0:33:03.039,0:33:09.760 +patch in instructions to continue + +0:33:06.720,0:33:11.600 +running that job with the bug fixed + +0:33:09.760,0:33:13.919 +in fact you could even do this with the + +0:33:11.600,0:33:16.640 +system kernel + +0:33:13.919,0:33:17.840 +so that your jobs wouldn't get lost i + +0:33:16.640,0:33:20.559 +did that + +0:33:17.840,0:33:22.720 +quite a few times of course sometimes i + +0:33:20.559,0:33:25.919 +saw what was wrong and i just had to + +0:33:22.720,0:33:28.240 +fix a piece of data but sometimes + +0:33:25.919,0:33:29.679 +it took me a long time to figure out how + +0:33:28.240,0:33:32.480 +to get the system to + +0:33:29.679,0:33:34.240 +keep on going but with the work i had + +0:33:32.480,0:33:39.279 +done + +0:33:34.240,0:33:41.600 +i didn't want to lose that work + +0:33:39.279,0:33:43.039 +and so one of the first features i put + +0:33:41.600,0:33:45.840 +into gdu emacs was + +0:33:43.039,0:33:45.840 +auto save + +0:33:47.760,0:33:54.320 +uh i'm not going to try to figure out + +0:33:50.640,0:33:56.480 +which packages i re i actually used + +0:33:54.320,0:33:59.039 +uh if i knew i would get hit by a bus + +0:33:56.480,0:34:02.320 +tomorrow + +0:33:59.039,0:34:05.039 +uh say because of a fortune teller + +0:34:02.320,0:34:06.240 +no a fortune teller doesn't give you any + +0:34:05.039,0:34:10.159 +knowledge it's just + +0:34:06.240,0:34:13.760 +superstitious uh hand waving + +0:34:10.159,0:34:16.480 +so assuming that i + +0:34:13.760,0:34:18.879 +talked that i got a reading from a + +0:34:16.480,0:34:23.119 +fortune teller which is + +0:34:18.879,0:34:25.040 +implausible enough to begin with uh + +0:34:23.119,0:34:28.320 +that wouldn't give me any knowledge + +0:34:25.040,0:34:32.879 +about what was going to happen to me + +0:34:28.320,0:34:34.960 +oh by the way fortune tellers generally + +0:34:32.879,0:34:36.879 +play back to you facts that they've + +0:34:34.960,0:34:40.480 +discovered about you + +0:34:36.879,0:34:43.440 +together with cold reading which means + +0:34:40.480,0:34:44.639 +they say things calculated to make it + +0:34:43.440,0:34:49.119 +appear that they know + +0:34:44.639,0:34:52.399 +more than they do or things that are + +0:34:49.119,0:34:55.679 +uh that sound wise to anyone + +0:34:52.399,0:34:58.800 +so you can say the same thing to + +0:34:55.679,0:35:02.000 +uh say 100 people + +0:34:58.800,0:35:05.359 +and 80 or 90 of them will say boy that + +0:35:02.000,0:35:05.359 +was really accurate + +0:35:06.480,0:35:14.880 +but what if for some reason + +0:35:10.400,0:35:14.880 +uh about + +0:35:15.119,0:35:18.560 +what what advice would i give for + +0:35:17.440,0:35:22.079 +stewardship of + +0:35:18.560,0:35:25.359 +emacs well basically + +0:35:22.079,0:35:28.480 +focus on + +0:35:25.359,0:35:29.280 +keeping the community strong in + +0:35:28.480,0:35:32.640 +defending + +0:35:29.280,0:35:34.400 +freedom if you have a choice between + +0:35:32.640,0:35:36.079 +keeping the community strong in + +0:35:34.400,0:35:38.800 +defending freedom + +0:35:36.079,0:35:40.720 +and getting more people to participate + +0:35:38.800,0:35:43.839 +in the development + +0:35:40.720,0:35:44.400 +you've got to choose the freedom it is + +0:35:43.839,0:35:48.400 +very + +0:35:44.400,0:35:52.320 +easy for free software projects to + +0:35:48.400,0:35:55.359 +subordinate freedom to other criteria + +0:35:52.320,0:35:58.079 +and once that happens it's + +0:35:55.359,0:35:58.720 +easy for those who don't care much about + +0:35:58.079,0:36:00.800 +freedom + +0:35:58.720,0:36:02.640 +such as sometimes companies that might + +0:36:00.800,0:36:08.160 +offer you some money + +0:36:02.640,0:36:10.560 +to purchase your soul + +0:36:08.160,0:36:14.240 +not that there are really things that + +0:36:10.560,0:36:16.560 +exist called souls it's a metaphor but + +0:36:14.240,0:36:18.800 +it's an important metaphor for something + +0:36:16.560,0:36:20.880 +important + +0:36:18.800,0:36:24.320 +people in the community have to be + +0:36:20.880,0:36:27.280 +thinking about freedom + +0:36:24.320,0:36:30.240 +when they make decisions about what is + +0:36:27.280,0:36:30.240 +wise to do + +0:36:31.839,0:36:39.839 +the decision to devel to set up non-glpa + +0:36:36.480,0:36:41.520 +has a drawback it was a compromise now a + +0:36:39.839,0:36:44.560 +lot of people will + +0:36:41.520,0:36:46.240 +tell you that i am uncompromising and + +0:36:44.560,0:36:48.720 +say that that's a flaw + +0:36:46.240,0:36:50.320 +well they're wrong i make little + +0:36:48.720,0:36:53.040 +compromises + +0:36:50.320,0:36:55.359 +very often and occasionally i make a + +0:36:53.040,0:36:58.880 +medium-sized compromise + +0:36:55.359,0:36:59.359 +the compromise is in the past we wanted + +0:36:58.880,0:37:01.599 +to get + +0:36:59.359,0:37:02.400 +copyright assignments for the packages + +0:37:01.599,0:37:06.240 +in gnu + +0:37:02.400,0:37:09.119 +elpa so that we could move them into + +0:37:06.240,0:37:11.200 +core emacs and of course sometimes we + +0:37:09.119,0:37:14.480 +move packages in the other direction + +0:37:11.200,0:37:16.160 +that way we are where we distribute a + +0:37:14.480,0:37:18.160 +given package + +0:37:16.160,0:37:20.720 +is something we can decide purely + +0:37:18.160,0:37:20.720 +technically + +0:37:20.880,0:37:26.800 +and however make insisting on getting + +0:37:25.200,0:37:28.640 +copyright assignments for all the + +0:37:26.800,0:37:32.079 +packages in gnu elpa + +0:37:28.640,0:37:35.119 +meant that we had to say sorry no + +0:37:32.079,0:37:38.560 +we will not install that packages in + +0:37:35.119,0:37:41.520 +packaging dewey lpa unless the + +0:37:38.560,0:37:44.079 +authors sign copyright assignments and + +0:37:41.520,0:37:47.520 +sometimes that's a lot of trouble + +0:37:44.079,0:37:50.160 +well non-glpa + +0:37:47.520,0:37:51.520 +won't require copyright assignments if + +0:37:50.160,0:37:54.560 +there's a free package + +0:37:51.520,0:37:57.200 +we can make whatever changes presumably + +0:37:54.560,0:38:00.560 +small otherwise we would probably say + +0:37:57.200,0:38:04.560 +we don't have time but and then + +0:38:00.560,0:38:05.599 +put it in but it does have the drawback + +0:38:04.560,0:38:07.680 +that + +0:38:05.599,0:38:09.119 +we in general we won't be able to move + +0:38:07.680,0:38:12.960 +those packages + +0:38:09.119,0:38:14.960 +into core emacs without + +0:38:12.960,0:38:19.839 +getting the legal papers then that we + +0:38:14.960,0:38:19.839 +didn't get before + +0:38:20.160,0:38:27.599 +how do you see the future of gdu emacs + +0:38:24.320,0:38:29.839 +uh i don't see the future + +0:38:27.599,0:38:31.680 +i used to say that my crystal ball is + +0:38:29.839,0:38:35.680 +cloudy today + +0:38:31.680,0:38:39.040 +unfortunately that has another + +0:38:35.680,0:38:41.200 +meaning which is quite ironic uh we + +0:38:39.040,0:38:44.800 +certainly don't want + +0:38:41.200,0:38:48.480 +our lives to be + +0:38:44.800,0:38:51.119 +somewhere in a cloud because + +0:38:48.480,0:38:51.599 +that clouds your mind and then people + +0:38:51.119,0:38:54.240 +start + +0:38:51.599,0:38:56.880 +cheating you and taking advantage of you + +0:38:54.240,0:39:00.160 +and it's horrible + +0:38:56.880,0:39:02.720 +but uh i don't see the future i just + +0:39:00.160,0:39:03.839 +can be sure from the past that there + +0:39:02.720,0:39:07.599 +will be + +0:39:03.839,0:39:10.720 +challenges where some of the people + +0:39:07.599,0:39:12.960 +involved want to make a big compromise + +0:39:10.720,0:39:16.880 +that isn't worth it + +0:39:12.960,0:39:18.079 +and they some they may even get the + +0:39:16.880,0:39:21.200 +impression that it's + +0:39:18.079,0:39:24.480 +up to them well actually + +0:39:21.200,0:39:27.440 +emacs has appointed maintainers just as + +0:39:24.480,0:39:29.280 +every gdu package does and they are the + +0:39:27.440,0:39:30.480 +ones in charge of developing that + +0:39:29.280,0:39:34.400 +package + +0:39:30.480,0:39:38.200 +and this is for a good reason + +0:39:34.400,0:39:39.760 +because the appointed maintainers take + +0:39:38.200,0:39:42.240 +responsibility + +0:39:39.760,0:39:44.079 +to carry out the gnu project policies + +0:39:42.240,0:39:46.160 +and most important of all + +0:39:44.079,0:39:47.520 +are the ones that make the whole system + +0:39:46.160,0:39:52.160 +work together + +0:39:47.520,0:39:52.160 +and the ethical standards + +0:39:52.640,0:39:57.839 +to respect freedom and defend freedom + +0:39:59.920,0:40:04.960 +is there any plan to move more packages + +0:40:02.240,0:40:08.480 +from core emacs into elpa + +0:40:04.960,0:40:11.440 +uh i don't know uh + +0:40:08.480,0:40:12.720 +whether there is a plan i suppose if + +0:40:11.440,0:40:15.680 +there's a plan + +0:40:12.720,0:40:16.960 +we probably would have done it if there + +0:40:15.680,0:40:19.839 +had been a plan + +0:40:16.960,0:40:20.319 +some have been moved i don't see this as + +0:40:19.839,0:40:22.400 +a + +0:40:20.319,0:40:24.160 +fundamentally important issue it's a + +0:40:22.400,0:40:26.640 +matter of what's convenient for + +0:40:24.160,0:40:29.599 +the users and their advantages and + +0:40:26.640,0:40:32.800 +disadvantages to each choice + +0:40:29.599,0:40:35.760 +what is your opinion on higher education + +0:40:32.800,0:40:36.720 +uh requiring non-free software for + +0:40:35.760,0:40:40.400 +instance + +0:40:36.720,0:40:43.440 +well i wouldn't i wouldn't + +0:40:40.400,0:40:49.119 +matriculate in a school which did that + +0:40:43.440,0:40:49.119 +unless i saw a way i could refuse + +0:40:50.960,0:40:57.760 +now of course i do this + +0:40:54.960,0:41:00.240 +because i can get away with it and + +0:40:57.760,0:41:04.960 +therefore my doing it is extremely + +0:41:00.240,0:41:08.400 +important to show somebody does resist + +0:41:04.960,0:41:09.359 +i don't expect most people who support + +0:41:08.400,0:41:12.319 +free school + +0:41:09.359,0:41:13.599 +who advocate free software to go that + +0:41:12.319,0:41:17.760 +far + +0:41:13.599,0:41:21.040 +uh i published an article in the spring + +0:41:17.760,0:41:24.640 +entitled saying no even once + +0:41:21.040,0:41:25.359 +is helping saying no to non-free + +0:41:24.640,0:41:29.040 +software + +0:41:25.359,0:41:32.240 +even once because + +0:41:29.040,0:41:34.640 +the more you do it the more you help but + +0:41:32.240,0:41:36.640 +even doing it a little in a way that + +0:41:34.640,0:41:39.920 +other people notice + +0:41:36.640,0:41:43.440 +is starting to help so + +0:41:39.920,0:41:45.119 +uh please don't think that your choices + +0:41:43.440,0:41:48.480 +are either + +0:41:45.119,0:41:52.240 +be as firm and stubborn as i am + +0:41:48.480,0:41:56.240 +or just give up and let yourself drift + +0:41:52.240,0:41:58.079 +helplessly as if you had no volition + +0:41:56.240,0:42:00.720 +there are a lot of points in between + +0:41:58.079,0:42:04.079 +there and you can surely + +0:42:00.720,0:42:07.839 +manage to say no some of the time + +0:42:04.079,0:42:11.040 +and show people an example of saying no + +0:42:07.839,0:42:12.720 +some of the time for instance you could + +0:42:11.040,0:42:15.520 +say to people + +0:42:12.720,0:42:16.000 +you know i hate the fact that my school + +0:42:15.520,0:42:20.400 +makes me + +0:42:16.000,0:42:22.240 +use zoom uh so whenever + +0:42:20.400,0:42:24.640 +i'm not being forced i'm not going to + +0:42:22.240,0:42:24.640 +use it + +0:42:25.760,0:42:31.200 +or i hate the fact that the only way i + +0:42:29.200,0:42:35.200 +can talk to that group of people + +0:42:31.200,0:42:38.400 +is resume but when + +0:42:35.200,0:42:40.079 +but for anything else i will feel better + +0:42:38.400,0:42:42.880 +about myself if i don't + +0:42:40.079,0:42:44.000 +see lots of ways to say no some of the + +0:42:42.880,0:42:47.040 +time + +0:42:44.000,0:42:50.960 +and yield some of the time + +0:42:47.040,0:42:53.920 +and when you try saying no occasionally + +0:42:50.960,0:42:56.400 +you may just develop the ability to say + +0:42:53.920,0:42:58.800 +no more often + +0:42:56.400,0:43:00.640 +now whether you would ever get to be as + +0:42:58.800,0:43:04.480 +stubborn as i am + +0:43:00.640,0:43:08.480 +i don't know but what i find is that + +0:43:04.480,0:43:12.480 +i like the fact that i've never made + +0:43:08.480,0:43:15.839 +this kind of compromise + +0:43:12.480,0:43:19.319 +i feel i have a reputation to maintain + +0:43:15.839,0:43:21.119 +nobody's forcing me but i get + +0:43:19.319,0:43:24.319 +satisfaction + +0:43:21.119,0:43:26.400 +out of maintaining out of being able to + +0:43:24.319,0:43:29.280 +continue to say + +0:43:26.400,0:43:29.280 +i will not + +0:43:30.880,0:43:40.480 +you are now unmuted and that also + +0:43:34.480,0:43:43.520 +can happen at various different levels + +0:43:40.480,0:43:46.640 +so you can get that satisfaction + +0:43:43.520,0:43:54.400 +of fully maintaining a refusal + +0:43:46.640,0:43:57.040 +that applies only to certain areas + +0:43:54.400,0:43:58.880 +citizens uh noon already let's maybe + +0:43:57.040,0:43:59.599 +take one or two more questions and then + +0:43:58.880,0:44:03.200 +break for + +0:43:59.599,0:44:06.000 +the lunch break okay thank you + +0:44:03.200,0:44:07.440 +how often do you personally use emacs as + +0:44:06.000,0:44:10.640 +the + +0:44:07.440,0:44:14.960 +lowest question now uh + +0:44:10.640,0:44:14.960 +well i use it most of the day + +0:44:16.640,0:44:20.160 +i occasionally do use other things in + +0:44:18.880,0:44:21.599 +fact i occasionally edit with + +0:44:20.160,0:44:24.240 +libreoffice + +0:44:21.599,0:44:25.280 +i occasionally use media players i + +0:44:24.240,0:44:27.520 +occasionally + +0:44:25.280,0:44:27.520 +uh + +0:44:29.040,0:44:34.000 +i occasionally ssh to a machine and type + +0:44:32.480,0:44:35.440 +some commands on it + +0:44:34.000,0:44:38.240 +which occasionally includes running + +0:44:35.440,0:44:38.240 +emacs on it + +0:44:42.319,0:44:47.520 +i read pdf files a lot + +0:44:45.760,0:44:49.599 +would be nice if you could get those + +0:44:47.520,0:44:52.240 +into emacs so that i could read them + +0:44:49.599,0:44:55.040 +with emacs commands + +0:44:52.240,0:44:56.160 +and i maybe even edit them with the max + +0:44:55.040,0:44:59.440 +commands + +0:44:56.160,0:45:02.960 +when they can be edited i use + +0:44:59.440,0:45:07.680 +uh journal sometimes + +0:45:02.960,0:45:07.680 +to write on a pdf file + +0:45:10.079,0:45:13.760 +are there any more interesting projects +

are things there are things that + +0:45:25.520,0:45:30.560 +the gnu project needs + +0:45:27.119,0:45:32.319 +doing there are packages that don't have + +0:45:30.560,0:45:35.839 +maintainers or could use + +0:45:32.319,0:45:38.880 +more maintainers uh + +0:45:35.839,0:45:42.000 +talk with maintainers at canoe.org + +0:45:38.880,0:45:44.960 +and the assistant candusences will + +0:45:42.000,0:45:47.839 +help you find a package where you can do + +0:45:44.960,0:45:47.839 +good + +0:45:48.400,0:45:52.079 +not for beginners though you got to get + +0:45:50.560,0:45:55.599 +you got to learn + +0:45:52.079,0:45:58.160 +uh a substantive substantial level of + +0:45:55.599,0:45:59.440 +capacity to develop and debug programs + +0:45:58.160,0:46:02.800 +before you can + +0:45:59.440,0:46:04.480 +be a maintainer uh have i ever looked at + +0:46:02.800,0:46:08.400 +maggot + +0:46:04.480,0:46:11.920 +uh no i haven't + +0:46:08.400,0:46:14.880 +but i believe + +0:46:11.920,0:46:16.560 +work is being done to get it put into + +0:46:14.880,0:46:21.200 +emacs + +0:46:16.560,0:46:21.200 +and at that point i'll give it a try + +0:46:22.240,0:46:25.760 +i do not

+0:00:03.280,0:00:09.200 +founder of the gnu project in 1976 i + +0:00:08.080,0:00:12.000 +developed the first + +0:00:09.200,0:00:13.440 +emacs editor with some help from guy + +0:00:12.000,0:00:15.839 +steele + +0:00:13.440,0:00:19.119 +then shortly after starting to develop + +0:00:15.839,0:00:22.240 +the gnu operating system in 1984 + +0:00:19.119,0:00:24.640 +i wanted an emacs editor for it + +0:00:22.240,0:00:25.560 +so i started writing gnu emacs in + +0:00:24.640,0:00:28.560 +september + +0:00:25.560,0:00:28.560 +1984. + +0:00:29.519,0:00:35.920 +several years ago we decided to move + +0:00:32.640,0:00:36.559 +many of the emacs list packages outside + +0:00:35.920,0:00:39.760 +the core + +0:00:36.559,0:00:42.960 +emacs distribution into a separate + +0:00:39.760,0:00:43.280 +package archive that we call the e-max + +0:00:42.960,0:00:46.480 +list + +0:00:43.280,0:00:48.719 +package arc elpa + +0:00:46.480,0:00:51.520 +there were two main reasons for this one + +0:00:48.719,0:00:54.320 +is to make the emax distribution smaller + +0:00:51.520,0:00:55.680 +so every user wouldn't have to get all + +0:00:54.320,0:00:58.320 +the packages + +0:00:55.680,0:01:00.480 +and install all the packages and the + +0:00:58.320,0:01:01.520 +other reason was to make it possible to + +0:01:00.480,0:01:04.559 +release + +0:01:01.520,0:01:08.320 +individual packages separately + +0:01:04.559,0:01:08.320 +from emacs releases + +0:01:08.880,0:01:17.040 +now at that point somehow we decided to + +0:01:13.119,0:01:19.520 +support loading packages from + +0:01:17.040,0:01:21.119 +a variety of different emacs list + +0:01:19.520,0:01:25.520 +package archives + +0:01:21.119,0:01:29.280 +and ours would be called the gnu elpa + +0:01:25.520,0:01:32.079 +but elpa could be any other + +0:01:29.280,0:01:32.799 +now i think that naming was a mistake we + +0:01:32.079,0:01:35.119 +should have + +0:01:32.799,0:01:37.759 +meant we should have decided that elpa + +0:01:35.119,0:01:39.759 +referred to our package archive + +0:01:37.759,0:01:42.479 +and any other package archive should be + +0:01:39.759,0:01:46.079 +called some other name + +0:01:42.479,0:01:48.320 +oh well uh this + +0:01:46.079,0:01:50.240 +is a mistake i believe because it leads + +0:01:48.320,0:01:51.119 +to a lot of confusion it would have been + +0:01:50.240,0:01:55.759 +clearer + +0:01:51.119,0:01:59.600 +if we had uh used the other naming + +0:01:55.759,0:02:00.399 +because the difference between having a + +0:01:59.600,0:02:04.159 +package in + +0:02:00.399,0:02:07.840 +core emacs and having it in gnu elpa + +0:02:04.159,0:02:09.679 +is purely a practical convenience matter + +0:02:07.840,0:02:12.000 +convenience of distribution and + +0:02:09.679,0:02:14.879 +convenience of maintenance + +0:02:12.000,0:02:16.800 +we wanted to be able to move packages + +0:02:14.879,0:02:20.160 +between the two + +0:02:16.800,0:02:21.200 +whenever that was convenient so to make + +0:02:20.160,0:02:23.200 +that possible + +0:02:21.200,0:02:26.319 +we insisted on getting copyright + +0:02:23.200,0:02:28.800 +assignments for packages in gnu elpa + +0:02:26.319,0:02:31.360 +just the same way we do for packages in + +0:02:28.800,0:02:33.760 +core emacs + +0:02:31.360,0:02:36.239 +having the facility for installing + +0:02:33.760,0:02:39.440 +packages from package archives + +0:02:36.239,0:02:42.239 +led to a tremendous boost in the + +0:02:39.440,0:02:44.879 +development and release of emax packages + +0:02:42.239,0:02:46.560 +unfortunately there was a problem with + +0:02:44.879,0:02:49.120 +the way that was done + +0:02:46.560,0:02:50.000 +for the most part the developers of + +0:02:49.120,0:02:52.480 +these packages + +0:02:50.000,0:02:53.599 +wouldn't even tell us about them they + +0:02:52.480,0:02:56.720 +posted them + +0:02:53.599,0:02:58.480 +in another package archive where we + +0:02:56.720,0:03:02.000 +didn't know about them + +0:02:58.480,0:03:03.120 +and where they no attempt was made to + +0:03:02.000,0:03:06.560 +try to fit them + +0:03:03.120,0:03:10.879 +into emacs so that they could make sense + +0:03:06.560,0:03:14.480 +as parts of the emacs distribution + +0:03:10.879,0:03:16.959 +this led to both moral problems + +0:03:14.480,0:03:19.599 +packages that depended on non-free + +0:03:16.959,0:03:22.159 +software in order to be usable + +0:03:19.599,0:03:24.319 +and technical problems because the + +0:03:22.159,0:03:26.159 +developers of those packages didn't + +0:03:24.319,0:03:29.519 +coordinate with us + +0:03:26.159,0:03:33.040 +about how to make it useful and + +0:03:29.519,0:03:36.000 +convenient and clean to have them + +0:03:33.040,0:03:36.000 +in emacs + +0:03:36.560,0:03:44.840 +so the idea of non-gdu elpa + +0:03:41.120,0:03:48.319 +is an effort to smooth these things + +0:03:44.840,0:03:51.680 +out the fundamental plan of + +0:03:48.319,0:03:54.480 +non-gnu eopa is that + +0:03:51.680,0:03:56.159 +we won't ask for copyright assignments + +0:03:54.480,0:03:58.560 +for those packages + +0:03:56.159,0:04:00.000 +so we won't be able to put them into + +0:03:58.560,0:04:04.080 +core emacs + +0:04:00.000,0:04:06.959 +at least not easily but we will + +0:04:04.080,0:04:09.200 +have some control over how we distribute + +0:04:06.959,0:04:09.200 +them + +0:04:09.519,0:04:15.439 +we can put any package into + +0:04:12.640,0:04:16.320 +non-gnu elpa as long as it's free + +0:04:15.439,0:04:19.440 +software + +0:04:16.320,0:04:23.360 +if we like it we can + +0:04:19.440,0:04:25.919 +set up that way for users to get it + +0:04:23.360,0:04:26.720 +we could put the package in exactly as + +0:04:25.919,0:04:29.919 +it is + +0:04:26.720,0:04:32.160 +if there's no problem at all with it + +0:04:29.919,0:04:34.160 +we can make an arrangement with the + +0:04:32.160,0:04:38.000 +packages developers + +0:04:34.160,0:04:40.880 +to work on it with us and maintain it + +0:04:38.000,0:04:42.560 +directly for distribution by non-gdu + +0:04:40.880,0:04:45.280 +elpa + +0:04:42.560,0:04:46.080 +but if they are not interested we can + +0:04:45.280,0:04:49.680 +put it in + +0:04:46.080,0:04:52.000 +ourselves and if we need to make any + +0:04:49.680,0:04:55.120 +changes we can do so + +0:04:52.000,0:04:59.040 +so non-gnu elpa + +0:04:55.120,0:05:01.360 +is not meant to be just a way + +0:04:59.040,0:05:02.720 +that others can distribute their + +0:05:01.360,0:05:05.039 +packages + +0:05:02.720,0:05:06.000 +it's meant at least in a minimal + +0:05:05.039,0:05:10.479 +technical + +0:05:06.000,0:05:12.800 +sense to work with gnu emacs and we'll + +0:05:10.479,0:05:14.240 +make changes if necessary so that it + +0:05:12.800,0:05:18.080 +works smoothly with + +0:05:14.240,0:05:18.080 +emacs and + +0:05:18.720,0:05:23.280 +this means that we're going to maintain + +0:05:22.160,0:05:27.600 +it differently + +0:05:23.280,0:05:29.759 +from gnu elpa well gnu elpa + +0:05:27.600,0:05:31.520 +is hosted in a way that is actually + +0:05:29.759,0:05:35.600 +rather inconvenient + +0:05:31.520,0:05:38.639 +it is one single git repository + +0:05:35.600,0:05:39.039 +and so anybody that has access to write + +0:05:38.639,0:05:42.560 +it + +0:05:39.039,0:05:44.639 +can write any part of it there are many + +0:05:42.560,0:05:46.080 +different packages in there maintained + +0:05:44.639,0:05:48.080 +by different people + +0:05:46.080,0:05:50.960 +and we have no way to give each one of + +0:05:48.080,0:05:54.720 +them access to per own package + +0:05:50.960,0:05:58.400 +and not to the others well with non-gnu + +0:05:54.720,0:05:59.440 +elpa we plan to fix that the idea is to + +0:05:58.400,0:06:02.479 +have + +0:05:59.440,0:06:05.600 +a single git repository where you can + +0:06:02.479,0:06:08.800 +download various packages from + +0:06:05.600,0:06:10.800 +but they won't be maintained there each + +0:06:08.800,0:06:14.080 +of those packages will be + +0:06:10.800,0:06:15.280 +copied automatically from some other + +0:06:14.080,0:06:18.800 +place + +0:06:15.280,0:06:21.759 +probably some other repository where + +0:06:18.800,0:06:22.960 +the right people have access to work on + +0:06:21.759,0:06:26.479 +it + +0:06:22.960,0:06:28.160 +and this way we can avoid giving a + +0:06:26.479,0:06:32.000 +gigantic number of people + +0:06:28.160,0:06:32.000 +access to every part of it + +0:06:32.240,0:06:40.479 +so far non-gnu elpa is just a plan + +0:06:37.039,0:06:43.280 +we need people to implement the plan + +0:06:40.479,0:06:45.120 +so if you would like to help please +

quick okay i can also try + +0:04:12.720,0:04:17.360 +um like increasing the volume here a + +0:04:14.959,0:04:17.360 +little bit + +0:04:17.919,0:04:21.440 +okay it doesn't sound all that quiet to + +0:04:20.000,0:04:23.840 +me just because we are + +0:04:21.440,0:04:24.479 +i'm being very familiar right now so the + +0:04:23.840,0:04:27.360 +volume + +0:04:24.479,0:04:28.479 +must be quite high compared to you no + +0:04:27.360,0:04:32.240 +yeah it's it's fine um + +0:04:28.479,0:04:35.919 +okay i think it's better now um anyways + +0:04:32.240,0:04:38.479 +let's see awesome yeah so yesterday + +0:04:35.919,0:04:40.800 +um you know so the setup that i'm using + +0:04:38.479,0:04:44.400 +this year for streaming the desktop + +0:04:40.800,0:04:47.919 +and the talks is that i use the um + +0:04:44.400,0:04:52.000 +script a a script by the fsf forks which + +0:04:47.919,0:04:54.400 +they also used for liquor planet + +0:04:52.000,0:04:56.240 +and so the thing with this script is + +0:04:54.400,0:04:57.040 +that it only takes one audio source by + +0:04:56.240,0:04:59.120 +default + +0:04:57.040,0:05:01.520 +and so i have that set to the desktop + +0:04:59.120,0:05:03.440 +audio so yesterday on the spot i had to + +0:05:01.520,0:05:05.199 +improvise to how to get my own audio on + +0:05:03.440,0:05:06.880 +the stream and i used mumbo + +0:05:05.199,0:05:08.720 +but then that added a delay which was + +0:05:06.880,0:05:10.720 +pretty annoying um + +0:05:08.720,0:05:13.120 +but today this morning i figured i could + +0:05:10.720,0:05:14.240 +use pulse audio's um monitor system to + +0:05:13.120,0:05:17.039 +add myself + +0:05:14.240,0:05:18.479 +um right on this machine um so that the + +0:05:17.039,0:05:19.840 +delay is shorter and + +0:05:18.479,0:05:21.759 +seems to be working well so i'm very + +0:05:19.840,0:05:24.080 +happy about that um + +0:05:21.759,0:05:24.960 +but anyways yeah so let's get on we have + +0:05:24.080,0:05:26.880 +the schedule +

sorts of interesting + +0:08:15.360,0:08:18.879 +conversation ideas and sometimes it's + +0:08:17.280,0:08:20.960 +nice to do it in real time or with + +0:08:18.879,0:08:23.360 +shared screens or things like that + +0:08:20.960,0:08:24.639 +so if you're having a conversation and + +0:08:23.360,0:08:28.000 +you want to have + +0:08:24.639,0:08:31.039 +more of a webcam or screen sharing thing + +0:08:28.000,0:08:32.800 +to enrich that discussion feel free to + +0:08:31.039,0:08:35.360 +set up a web conference using any of + +0:08:32.800,0:08:36.880 +your okay + +0:08:35.360,0:08:38.880 +can you do time in practice later all + +0:08:36.880,0:08:41.760 +right feel free to + +0:08:38.880,0:08:43.120 +set up your own conference c type web + +0:08:41.760,0:08:46.080 +conference thingy + +0:08:43.120,0:08:47.279 +and um and go find the people who are + +0:08:46.080,0:08:49.839 +interested in the same thing + +0:08:47.279,0:08:50.480 +and i'll do all that stuff right + +0:08:49.839,0:08:53.120 +absolutely + +0:08:50.480,0:08:53.760 +thanks sasha yeah so basically the idea + +0:08:53.120,0:08:55.360 +is that + +0:08:53.760,0:08:58.080 +so you know because of the limited time + +0:08:55.360,0:09:00.720 +we kind of have to um keep moving along + +0:08:58.080,0:09:02.240 +uh from one talk to the next and you + +0:09:00.720,0:09:04.080 +know sometimes there's a lot of awesome + +0:09:02.240,0:09:05.760 +questions or discussions going on + +0:09:04.080,0:09:08.240 +from for example you know in emacs con + +0:09:05.760,0:09:11.440 +for like for the questions on the pad + +0:09:08.240,0:09:12.160 +um yeah so the i guess hallway track or + +0:09:11.440,0:09:15.360 +unconference + +0:09:12.160,0:09:16.160 +is basically a suggestion for those who + +0:09:15.360,0:09:19.120 +are interested + +0:09:16.160,0:09:21.120 +to for example set up a jutsu meet room + +0:09:19.120,0:09:23.519 +and then you know i'll go join there + +0:09:21.120,0:09:25.279 +and discuss the talk if you know if the + +0:09:23.519,0:09:26.240 +speaker can join after their talk + +0:09:25.279,0:09:29.519 +wonderful + +0:09:26.240,0:09:31.519 +um but if not even um you know if if + +0:09:29.519,0:09:34.000 +only like you know the audience and + +0:09:31.519,0:09:35.760 +folks you know from the emax campfire c + +0:09:34.000,0:09:37.279 +would like to join and discuss that + +0:09:35.760,0:09:40.320 +definitely works too + +0:09:37.279,0:09:42.000 +um yeah that's it um + +0:09:40.320,0:09:44.560 +i think oh one other thing that we i + +0:09:42.000,0:09:46.560 +guess wanted to mention possibly is that + +0:09:44.560,0:09:48.640 +um yesterday i think i noticed that a + +0:09:46.560,0:09:52.240 +lot of the questions were getting added + +0:09:48.640,0:09:54.560 +um like top to bottom on the pad but um + +0:09:52.240,0:09:56.000 +i think the suggestion is to put them + +0:09:54.560,0:09:58.000 +like stack them up so like + +0:09:56.000,0:09:59.360 +um add new at the new questions on the + +0:09:58.000,0:10:01.600 +top um + +0:09:59.360,0:10:03.120 +that might make it easier both for you + +0:10:01.600,0:10:05.760 +know the people + +0:10:03.120,0:10:07.120 +to who are typing the questions um but + +0:10:05.760,0:10:09.519 +also for the speaker to + +0:10:07.120,0:10:10.720 +sort of have a fixed i guess um point + +0:10:09.519,0:10:11.760 +where they're looking at for new + +0:10:10.720,0:10:13.839 +questions + +0:10:11.760,0:10:15.200 +um so don't put your questions under + +0:10:13.839,0:10:17.760 +somebody else's question + +0:10:15.200,0:10:18.640 +put it at that top level sort of you + +0:10:17.760,0:10:21.519 +know thing + +0:10:18.640,0:10:23.040 +right get your own bullet points yeah + +0:10:21.519,0:10:24.480 +and on the same topic yesterday some + +0:10:23.040,0:10:26.959 +people were a little scared + +0:10:24.480,0:10:27.839 +when all the colors were removed it was + +0:10:26.959,0:10:29.839 +me basically + +0:10:27.839,0:10:31.680 +in order to help the speakers know which + +0:10:29.839,0:10:33.680 +is the section that should be looking at + +0:10:31.680,0:10:35.200 +at the start of every presentation what + +0:10:33.680,0:10:35.760 +i will do is that i will wipe all the + +0:10:35.200,0:10:38.480 +colors + +0:10:35.760,0:10:39.360 +so all the attributions of modifications + +0:10:38.480,0:10:41.600 +to authors + +0:10:39.360,0:10:43.200 +so that the streamer sorry the speaker + +0:10:41.600,0:10:44.480 +has a little easier time finding their + +0:10:43.200,0:10:47.200 +talk in the list + +0:10:44.480,0:10:48.560 +right yeah so yeah for for speakers just + +0:10:47.200,0:10:49.360 +keep scrolling down until you hit a + +0:10:48.560,0:10:52.079 +colorful + +0:10:49.360,0:10:52.640 +colorful section um with the author + +0:10:52.079,0:10:55.600 +colors + +0:10:52.640,0:10:57.200 +and um yeah double check that um

+0:21:47.520,0:21:50.799 +probably heard of the town where i live + +0:21:49.760,0:21:54.559 +recently + +0:21:50.799,0:21:58.000 +as a direct um + +0:21:54.559,0:22:02.400 +uh kind of crucible there

+0:22:06.320,0:22:10.400 +down + +0:22:07.280,0:22:12.320 +without assuming people are gonna write + +0:22:10.400,0:22:15.600 +you off as a shyster + +0:22:12.320,0:22:16.640 +that's insanity we know exactly what + +0:22:15.600,0:22:20.480 +that means + +0:22:16.640,0:22:23.679 +especially in this community we uh + +0:22:20.480,0:22:26.640 +we're here because we want to + +0:22:23.679,0:22:27.200 +um because we want to make sure that + +0:22:26.640,0:22:29.280 +some + +0:22:27.200,0:22:30.880 +part of what the potential that + +0:22:29.280,0:22:32.880 +technology offers + +0:22:30.880,0:22:34.320 +is indelibly written out there that + +0:22:32.880,0:22:36.799 +nobody can take away + +0:22:34.320,0:22:38.240 +that's the bottom line on that that that + +0:22:36.799,0:22:40.240 +closing thought i mean that's where i'd + +0:22:38.240,0:22:41.919 +leave you at with emacs conference + +0:22:40.240,0:22:43.280 +you want to make stuff that other people + +0:22:41.919,0:22:44.320 +can't take away because that's where + +0:22:43.280,0:22:47.120 +freedom + +0:22:44.320,0:22:47.120 +is hiding + +0:22:48.320,0:22:52.799 +thank you and i agree there is something + +0:22:51.360,0:22:55.039 +to be said about + +0:22:52.799,0:22:56.080 +um you know this idea of having some + +0:22:55.039,0:22:59.360 +piece of software + +0:22:56.080,0:23:01.679 +or an art form to um + +0:22:59.360,0:23:03.360 +setting it free to to live on + +0:23:01.679,0:23:04.400 +indefinitely into the future and for + +0:23:03.360,0:23:06.320 +everyone else + +0:23:04.400,0:23:07.600 +um and for people who may have not + +0:23:06.320,0:23:09.679 +already even been born + +0:23:07.600,0:23:11.280 +to you know at some point someday + +0:23:09.679,0:23:13.840 +discover it and + +0:23:11.280,0:23:15.039 +um you know start using it and making it + +0:23:13.840,0:23:18.880 +even better + +0:23:15.039,0:23:21.120 +um yeah so i think on that note + +0:23:18.880,0:23:23.039 +this might be a good note to conclude on + +0:23:21.120,0:23:24.720 +what you folks think + +0:23:23.039,0:23:26.640 +i always like to go around the room one + +0:23:24.720,0:23:28.240 +time but again i'll keep everybody on + +0:23:26.640,0:23:30.960 +the phone forever so don't + +0:23:28.240,0:23:31.860 +don't don't use my definitely i have to +

+0:23:40.240,0:23:43.840 +as many questions as we could + +0:23:41.760,0:23:45.440 +from the people because i believe we've + +0:23:43.840,0:23:47.520 +answered some of them and sasha has been + +0:23:45.440,0:23:49.360 +kind enough to answer them in line + +0:23:47.520,0:23:50.960 +but maybe we wanted to take some of them + +0:23:49.360,0:23:52.080 +live especially some of the later ones + +0:23:50.960,0:23:54.320 +just to + +0:23:52.080,0:23:56.240 +send people off with a feeling that we + +0:23:54.320,0:23:58.640 +answered to the very last question that + +0:23:56.240,0:24:01.360

+0:25:32.400,0:25:36.320 +so yeah i was very impressed by this + +0:25:36.480,0:25:40.320 +yeah it's awesome just seeing the wide + +0:25:39.039,0:25:43.600 +diversity and the wide + +0:25:40.320,0:25:45.200 +age range of people um just getting into + +0:25:43.600,0:25:48.240 +emacs picking up + +0:25:45.200,0:25:49.840 +for all sorts of different things um + +0:25:48.240,0:25:51.440 +corbin and i had a bit of a chat about + +0:25:49.840,0:25:53.440 +this about this + +0:25:51.440,0:25:54.960 +piece of free software that is emacs and + +0:25:53.440,0:25:58.320 +all the freedoms + +0:25:54.960,0:25:58.960 +freedoms that it grants us um but yeah + +0:25:58.320,0:26:02.080 +we could + +0:25:58.960,0:26:02.559 +go on forever and ever um yeah i really + +0:26:02.080,0:26:05.039 +can + +0:26:02.559,0:26:06.400 +and then and you know and it has to be + +0:26:05.039,0:26:07.440 +about getting something done and that's + +0:26:06.400,0:26:11.679 +where i think + +0:26:07.440,0:26:15.679 +sasha your work and organization is so + +0:26:11.679,0:26:18.799 +uh vital to us + +0:26:15.679,0:26:20.720 +we uh you know we have to direct that + +0:26:18.799,0:26:22.480 +energy into self-organizing + +0:26:20.720,0:26:24.159 +and and that's where i'd like probably + +0:26:22.480,0:26:26.159 +to focus my work + +0:26:24.159,0:26:27.200 +over the probably the next several years + +0:26:26.159,0:26:31.120 +is + +0:26:27.200,0:26:32.000 +um is is putting that thought and some + +0:26:31.120,0:26:34.720 +of the + +0:26:32.000,0:26:35.600 +uh some of the ideas that are built into + +0:26:34.720,0:26:37.200 +org mode and + +0:26:35.600,0:26:38.720 +in fact some of the implementation + +0:26:37.200,0:26:40.240 +that's built into org one and in fact + +0:26:38.720,0:26:43.440 +probably org mode + +0:26:40.240,0:26:46.159 +because hey there it is + +0:26:43.440,0:26:47.279 +to work on that yeah you should see all + +0:26:46.159,0:26:50.320 +the org scripts i wrote + +0:26:47.279,0:26:51.760 +so cool not that other people but anyway + +0:26:50.320,0:26:52.000 +we wrote this like fancy scheduling +
