-00:00:27.680 --> 00:00:29.840 -some ideas that are prerequisites for - -00:00:29.840 --> 00:00:31.039 -understanding the rest of the - -00:00:31.039 --> 00:00:32.320 -presentation - -00:00:32.320 --> 00:00:35.440 -the three main keys of ev are matay meta -

-00:00:44.960 --> 00:00:46.800 -technically it is - -00:00:46.800 --> 00:00:49.680 -essentially just a ctrl e to move to the - -00:00:49.680 --> 00:00:50.879 -end of the line and then - -00:00:50.879 --> 00:00:54.320 -a ctrl x control e to execute this the - -00:00:54.320 --> 00:00:58.960 -sext before point at the end of the line - -00:00:58.960 --> 00:01:00.879 -and the thing is that a max comes with - -00:01:00.879 --> 00:01:03.120 -many functions that can be used as sex - -00:01:03.120 --> 00:01:05.040 -hyperlinks - -00:01:05.040 --> 00:01:07.040 -we can consider that they point to - -00:01:07.040 --> 00:01:09.040 -somewhere I'm going to refer to that as - -00:01:09.040 --> 00:01:09.520 -the - -00:01:09.520 --> 00:01:11.920 -target of the hyperlink and if we - -00:01:11.920 --> 00:01:12.960 -execute this - -00:01:12.960 --> 00:01:15.759 -sex paper links would go to that target - -00:01:15.759 --> 00:01:17.119 -for example this one - -00:01:17.119 --> 00:01:20.000 -is a hyperlink that points to a buffer - -00:01:20.000 --> 00:01:22.720 -with demand paid for cat - -00:01:22.720 --> 00:01:25.040 -and usually but not always after - -00:01:25.040 --> 00:01:27.040 -following the hyperlink we can go back - -00:01:27.040 --> 00:01:29.840 -by just skilling the the current buffer - -00:01:29.840 --> 00:01:30.720 -that the hyperlink - -00:01:30.720 --> 00:01:34.400 -created the target of the hyperlink - -00:01:34.400 --> 00:01:38.000 -but this example here is badly behaved - -00:01:38.000 --> 00:01:41.360 -if we execute it it creates a new frame - -00:01:41.360 --> 00:01:43.360 -and to go back to the previous situation - -00:01:43.360 --> 00:01:44.640 -we have to either - -00:01:44.640 --> 00:01:52.840 -click here or type ctrl x50 - -00:01:52.840 --> 00:01:54.880 -uh - -00:01:54.880 --> 00:01:57.520 -so here are some examples of sex - -00:01:57.520 --> 00:02:00.640 -hyperlinks using standard max functions - -00:02:00.640 --> 00:02:03.600 -this third one is uh badly behaved in a - -00:02:03.600 --> 00:02:04.880 -different way - -00:02:04.880 --> 00:02:08.879 -if executed we the target is created in - -00:02:08.879 --> 00:02:09.840 -the same window - -00:02:09.840 --> 00:02:13.840 -as we are now but it also shows a lot of - -00:02:13.840 --> 00:02:16.000 -garbage here in the aqua area so - -00:02:16.000 --> 00:02:20.840 -the the current frame becomes a bit - -00:02:20.840 --> 00:02:23.280 -messy - -00:02:23.280 --> 00:02:26.160 -and well one of the first things that I - -00:02:26.160 --> 00:02:28.319 -did when I was creating av - -00:02:28.319 --> 00:02:30.720 -many many years ago was that I created - -00:02:30.720 --> 00:02:31.680 -variants - -00:02:31.680 --> 00:02:34.840 -of all these functions that were better - -00:02:34.840 --> 00:02:36.640 -behaved - -00:02:36.640 --> 00:02:38.640 -and they were better behaved in two - -00:02:38.640 --> 00:02:40.480 -senses the obvious one - -00:02:40.480 --> 00:02:43.040 -was that they they all created the - -00:02:43.040 --> 00:02:43.680 -target - -00:02:43.680 --> 00:02:45.840 -in the same window as before so I could - -00:02:45.840 --> 00:02:48.720 -go back by just typing meta k - -00:02:48.720 --> 00:02:51.040 -which is essentially just killed this - -00:02:51.040 --> 00:02:52.879 -buffer - -00:02:52.879 --> 00:02:55.200 -and well but I also implemented - -00:02:55.200 --> 00:02:56.480 -something extra that - -00:02:56.480 --> 00:02:59.040 -are the post back lists for example for - -00:02:59.040 --> 00:02:59.840 -example these - -00:02:59.840 --> 00:03:03.599 -extra arguments here are a postback list - -00:03:03.599 --> 00:03:06.080 -and this extra arguments specify - -00:03:06.080 --> 00:03:09.599 -position and the target buffer - -00:03:09.599 --> 00:03:13.040 -and in this example this this spot - -00:03:13.040 --> 00:03:16.720 -spec list means starting from the from - -00:03:16.720 --> 00:03:18.239 -the beginning of the buffer - -00:03:18.239 --> 00:03:20.560 -search for the first occurrence of this - -00:03:20.560 --> 00:03:22.239 -string - -00:03:22.239 --> 00:03:24.159 -after that after the beginning of the - -00:03:24.159 --> 00:03:25.519 -buffer and then - -00:03:25.519 --> 00:03:28.159 -search for the first occurrence of this - -00:03:28.159 --> 00:03:29.120 -string - -00:03:29.120 --> 00:03:33.760 -after that - -00:03:33.760 --> 00:03:36.560 -eev also defines some hyperlinks that do - -00:03:36.560 --> 00:03:38.799 -not create new buffers - -00:03:38.799 --> 00:03:41.280 -uh here is the first example if I - -00:03:41.280 --> 00:03:41.840 -execute - -00:03:41.840 --> 00:03:45.920 -this one this one is a hyperlink to the - -00:03:45.920 --> 00:03:46.959 -to the result - -00:03:46.959 --> 00:03:50.720 -of running this show comment date uh - -00:03:50.720 --> 00:03:52.959 -but instead of showing the result in the - -00:03:52.959 --> 00:03:55.040 -new buffer the result is shown - -00:03:55.040 --> 00:03:58.959 -here so if execute to this type link - -00:03:58.959 --> 00:04:01.840 -the result of date the output of data is - -00:04:01.840 --> 00:04:04.239 -shown in the echo area and if executed - -00:04:04.239 --> 00:04:07.120 -again - -00:04:07.120 --> 00:04:09.519 -it shows the result again and the result - -00:04:09.519 --> 00:04:11.519 -changes every second - -00:04:11.519 --> 00:04:15.200 -and if so this is a variant - -00:04:15.200 --> 00:04:18.720 -of fine sh - -00:04:18.720 --> 00:04:21.840 -uh find sh0 is the variant that - -00:04:21.840 --> 00:04:24.960 -just shows the output in the echo area - -00:04:24.960 --> 00:04:28.080 -and find sh shows the output in - -00:04:28.080 --> 00:04:31.759 -a new buffer - -00:04:31.759 --> 00:04:35.919 -and here is an example of a hyperlink - -00:04:35.919 --> 00:04:37.520 -that - -00:04:37.520 --> 00:04:40.000 -calls an external program if execute - -00:04:40.000 --> 00:04:41.280 -this - -00:04:41.280 --> 00:04:43.759 -it it calls google chrome to open a - -00:04:43.759 --> 00:04:46.639 -certain url - -00:04:46.639 --> 00:04:51.520 -here it is let's go back to mx - -00:04:51.520 --> 00:04:55.280 -if execute this happening here - -00:04:55.280 --> 00:04:58.479 -it invokes my favorite pdf viewer which - -00:04:58.479 --> 00:04:58.880 -is - -00:04:58.880 --> 00:05:02.560 -xpdf it makes xpdf - -00:05:02.560 --> 00:05:07.759 -open this pdf page it is pdf - -00:05:07.759 --> 00:05:10.880 -in this page and this other arguments - -00:05:10.880 --> 00:05:15.199 -are ignored let me show how it works - -00:05:15.199 --> 00:05:19.120 -here it is this is a an accept from a - -00:05:19.120 --> 00:05:20.160 -book - -00:05:20.160 --> 00:05:22.639 -so page 3 and the pdf corresponds to - -00:05:22.639 --> 00:05:23.199 -page - -00:05:23.199 --> 00:05:26.400 -113 in the book and - -00:05:26.400 --> 00:05:29.360 -this variant here of the hyperlink above - -00:05:29.360 --> 00:05:31.759 -it opens the pdf in a different way - -00:05:31.759 --> 00:05:34.560 -it runs a program called pdf to text on - -00:05:34.560 --> 00:05:36.479 -this pdf here - -00:05:36.479 --> 00:05:39.600 -and max takes the output of - -00:05:39.600 --> 00:05:42.880 -run epd after text on this pdf here - -00:05:42.880 --> 00:05:46.080 -and displays it in a buffer and now this - -00:05:46.080 --> 00:05:47.280 -postback list - -00:05:47.280 --> 00:05:50.000 -is interpreted in a different way this - -00:05:50.000 --> 00:05:51.280 -thing is interpreted - -00:05:51.280 --> 00:05:54.400 -as a as a number of a page and a max - -00:05:54.400 --> 00:05:54.800 -goes - -00:05:54.800 --> 00:05:57.520 -to page three by counting form feeds in - -00:05:57.520 --> 00:05:58.240 -the - -00:05:58.240 --> 00:06:01.440 -converted version of the pdf and then it - -00:06:01.440 --> 00:06:03.039 -searches for this string - -00:06:03.039 --> 00:06:06.319 -and in this three so let's execute this - -00:06:06.319 --> 00:06:08.479 -to see what happens - -00:06:08.479 --> 00:06:10.800 -here it is I opened the same page as - -00:06:10.800 --> 00:06:14.800 -before - -00:06:14.800 --> 00:06:18.400 -it starts with lecture one so - -00:06:18.400 --> 00:06:20.720 -the other hyperlink searched for this - -00:06:20.720 --> 00:06:25.520 -string and for this string here - -00:06:25.520 --> 00:06:28.160 -uh and this thing here is a hyperlink to - -00:06:28.160 --> 00:06:30.400 -video - -00:06:30.400 --> 00:06:32.720 -and when I executed it's going to open - -00:06:32.720 --> 00:06:34.560 -this video here - -00:06:34.560 --> 00:06:37.759 -at this time this time stamp let's see - -00:06:37.759 --> 00:06:41.199 -one two three one - -00:06:41.199 --> 00:06:46.840 -two three that's the way to do - -00:06:46.840 --> 00:06:49.440 -it - -00:06:49.440 --> 00:06:52.560 -and also some hyperlinks that that I - -00:06:52.560 --> 00:06:53.680 -defined - -00:06:53.680 --> 00:06:56.479 -uh they don't work like like usual - -00:06:56.479 --> 00:06:58.160 -hyperlinks they work more - -00:06:58.160 --> 00:07:01.440 -like browser buttons - -00:07:01.440 --> 00:07:06.240 -these buttons that appear in web pages - -00:07:06.240 --> 00:07:09.120 -in the sense that these buttons usually - -00:07:09.120 --> 00:07:11.360 -don't open a new page they usually - -00:07:11.360 --> 00:07:13.280 -just do something to change the current - -00:07:13.280 --> 00:07:14.960 -page - -00:07:14.960 --> 00:07:18.160 -if I execute this the action of this - -00:07:18.160 --> 00:07:18.880 -function - -00:07:18.880 --> 00:07:22.240 -eek is to uh - -00:07:22.240 --> 00:07:24.800 -it interprets this string as a series of - -00:07:24.800 --> 00:07:25.919 -keys and it - -00:07:25.919 --> 00:07:28.840 -acts as if the user had typed all these - -00:07:28.840 --> 00:07:30.319 -keys so - -00:07:30.319 --> 00:07:33.680 -if executed I get a hello in the next - -00:07:33.680 --> 00:07:34.400 -line - -00:07:34.400 --> 00:07:36.639 -if executed again I get another hello - -00:07:36.639 --> 00:07:39.440 -another hello hello hello etc etc - -00:07:39.440 --> 00:07:44.319 -let me undo this mess oops - -00:07:44.319 --> 00:07:47.840 -and here is another kind of button - -00:07:47.840 --> 00:07:51.440 -that defines a new function if I execute - -00:07:51.440 --> 00:07:54.879 -this sex here at this moment though is - -00:07:54.879 --> 00:07:55.759 -not defined - -00:07:55.759 --> 00:07:57.919 -and if I execute this mx is going to - -00:07:57.919 --> 00:08:00.000 -show me a message saying - -00:08:00.000 --> 00:08:03.599 -uh symbols function cell is not defined - -00:08:03.599 --> 00:08:05.840 -something like this - -00:08:05.840 --> 00:08:09.520 -but if I execute the defund - -00:08:09.520 --> 00:08:12.960 -this the action of this function o here - -00:08:12.960 --> 00:08:16.479 -is to run this which opens a certain - -00:08:16.479 --> 00:08:18.960 -directory - -00:08:18.960 --> 00:08:21.840 -let me go back and here is another - -00:08:21.840 --> 00:08:23.039 -button that defines - -00:08:23.039 --> 00:08:25.840 -several functions at the same time if I - -00:08:25.840 --> 00:08:26.479 -execute - -00:08:26.479 --> 00:08:32.320 -this - -00:08:32.320 --> 00:08:35.599 -note that the the result of executing - -00:08:35.599 --> 00:08:36.719 -this expression - -00:08:36.719 --> 00:08:38.640 -is the name of one of the functions that - -00:08:38.640 --> 00:08:40.080 -it defined - -00:08:40.080 --> 00:08:42.800 -that is this one here and let me explain - -00:08:42.800 --> 00:08:43.360 -the - -00:08:43.360 --> 00:08:46.959 -these examples uh one of the functions - -00:08:46.959 --> 00:08:48.800 -that this thing here defined - -00:08:48.800 --> 00:08:51.839 -is called find or git file where - -00:08:51.839 --> 00:08:54.640 -this or gate in the middle of its name - -00:08:54.640 --> 00:08:55.040 -is - -00:08:55.040 --> 00:08:59.600 -exactly this first argument to code cd - -00:08:59.600 --> 00:09:02.640 -and the action of running find or get - -00:09:02.640 --> 00:09:03.120 -file - -00:09:03.120 --> 00:09:06.399 -on a string like this is that - -00:09:06.399 --> 00:09:09.680 -find or get file takes the string - -00:09:09.680 --> 00:09:13.360 -and prepends this string to it - -00:09:13.360 --> 00:09:15.600 -this one here which is the second - -00:09:15.600 --> 00:09:17.920 -argument to called cd - -00:09:17.920 --> 00:09:21.760 -and then it executes find flying - -00:09:21.760 --> 00:09:25.680 -on the result which is this one - -00:09:25.680 --> 00:09:28.320 -and fine flying is my variant of find - -00:09:28.320 --> 00:09:28.800 -file - -00:09:28.800 --> 00:09:32.080 -that supports both spec lists - -00:09:32.080 --> 00:09:36.880 -and this function here that I'm - -00:09:36.880 --> 00:09:39.600 -referring to as a button it also defines - -00:09:39.600 --> 00:09:41.200 -a function called - -00:09:41.200 --> 00:09:44.880 -find audit node here where the or gate - -00:09:44.880 --> 00:09:46.080 -is the same string - -00:09:46.080 --> 00:09:50.320 -as here and this function opens a node - -00:09:50.320 --> 00:09:54.160 -of of an info manual this one - -00:09:54.160 --> 00:09:57.920 -this text here opens this node in the - -00:09:57.920 --> 00:10:00.080 -org manual - -00:10:00.080 --> 00:10:03.519 -it is equivalent to this text here - -00:10:03.519 --> 00:10:06.800 -so in the passage from this line to this - -00:10:06.800 --> 00:10:08.720 -line we prepended - -00:10:08.720 --> 00:10:11.920 -to the node name the name of the manual - -00:10:11.920 --> 00:10:15.040 -here and find node is my variant - -00:10:15.040 --> 00:10:18.160 -of this standard mx function here - -00:10:18.160 --> 00:10:20.399 -but find node also supports post - -00:10:20.399 --> 00:10:23.519 -backlists - -00:10:23.519 --> 00:10:26.640 -eevee also defines some functions that - -00:10:26.640 --> 00:10:28.640 -define shorter hyperlinks to pdfs and - -00:10:28.640 --> 00:10:30.800 -videos - -00:10:30.800 --> 00:10:32.880 -remember that this thing here is a - -00:10:32.880 --> 00:10:34.720 -shorter hyperlink to a - -00:10:34.720 --> 00:10:37.120 -to a file and this thing here is a - -00:10:37.120 --> 00:10:39.040 -shorter hyperlink to a node and - -00:10:39.040 --> 00:10:43.200 -in an mx menu in an info manual - -00:10:43.200 --> 00:10:46.079 -uh if we run this thing here this code - -00:10:46.079 --> 00:10:47.279 -pdf page - -00:10:47.279 --> 00:10:50.240 -this acts like a button that defines a - -00:10:50.240 --> 00:10:52.880 -certain function - -00:10:52.880 --> 00:10:56.399 -and this string this other sex - -00:10:56.399 --> 00:10:59.040 -here defines another function the first - -00:10:59.040 --> 00:11:00.240 -one defines - -00:11:00.240 --> 00:11:03.040 -the function find funcspivac page and - -00:11:03.040 --> 00:11:05.360 -the second one defines the function find - -00:11:05.360 --> 00:11:09.279 -from text when we run the - -00:11:09.279 --> 00:11:12.240 -file when we run findfoxpivotpage it - -00:11:12.240 --> 00:11:13.440 -opens - -00:11:13.440 --> 00:11:17.600 -this pdf here the name is - -00:11:17.600 --> 00:11:20.640 -quite long uh - -00:11:20.640 --> 00:11:23.839 -this example opens this pdf at page 8 - -00:11:23.839 --> 00:11:26.079 -and searches for the string contents - -00:11:26.079 --> 00:11:28.000 -oops sorry in this case - -00:11:28.000 --> 00:11:31.279 -in this case it just ignores this string - -00:11:31.279 --> 00:11:33.519 -here it only considers - -00:11:33.519 --> 00:11:37.360 -the number of the page let's try - -00:11:37.360 --> 00:11:42.640 -ah we got - -00:11:42.640 --> 00:11:45.200 -here it is uh the contents of a book - -00:11:45.200 --> 00:11:46.880 -that is freely - -00:11:46.880 --> 00:11:50.800 -available uh here is another page of the - -00:11:50.800 --> 00:11:51.760 -book - -00:11:51.760 --> 00:11:55.040 -and if we execute the this happening - -00:11:55.040 --> 00:11:55.519 -here - -00:11:55.519 --> 00:11:58.399 -find funk's pivot text it converts the - -00:11:58.399 --> 00:11:59.920 -pdf to text - -00:11:59.920 --> 00:12:03.040 -and it searches for the page eight - -00:12:03.040 --> 00:12:05.040 -in it and then for the string this - -00:12:05.040 --> 00:12:08.079 -string here in page eight - -00:12:08.079 --> 00:12:12.240 -it takes a few seconds - -00:12:12.240 --> 00:12:16.160 -here it is so this is the - -00:12:16.160 --> 00:12:20.320 -ascii version of this contents page - -00:12:20.320 --> 00:12:25.040 -here uh note that this block here - -00:12:25.040 --> 00:12:28.800 -is a kind of an index to that book - -00:12:28.800 --> 00:12:31.680 -uh I have the full index somewhere but - -00:12:31.680 --> 00:12:33.600 -it's very long so I just copied a few - -00:12:33.600 --> 00:12:34.959 -lines here - -00:12:34.959 --> 00:12:38.959 -uh so this is a link to the to set - -00:12:38.959 --> 00:12:42.160 -section one chapter one this is the - -00:12:42.160 --> 00:12:45.360 -section 1.1 - -00:12:45.360 --> 00:12:48.959 -section 1.1.1 and so on - -00:12:48.959 --> 00:12:54.000 -and here is a link to the index - -00:12:54.000 --> 00:12:58.079 -and here is a part of my index - -00:12:58.079 --> 00:13:02.800 -of positions in the video that we just - -00:13:02.800 --> 00:13:03.279 -saw - -00:13:03.279 --> 00:13:05.760 -that I think that are especially - -00:13:05.760 --> 00:13:07.360 -relevant - -00:13:07.360 --> 00:13:10.639 -uh so this I believe - -00:13:10.639 --> 00:13:12.399 -hyperlink is a kind of a button that - -00:13:12.399 --> 00:13:14.160 -defines this function here - -00:13:14.160 --> 00:13:18.839 -find punch and punch into the video - -00:13:18.839 --> 00:13:27.600 -uh - -00:13:27.600 --> 00:13:31.440 -and we can also use this for video - -00:13:31.440 --> 00:13:33.360 -tutorials for example - -00:13:33.360 --> 00:13:37.200 -this is a very good tutorial on on magic - -00:13:37.200 --> 00:13:40.880 -if we execute this - -00:13:40.880 --> 00:13:42.560 -then these functions are going to be - -00:13:42.560 --> 00:13:44.800 -defined and these functions open - -00:13:44.800 --> 00:13:48.399 -this tutorial on magic - -00:13:48.399 --> 00:13:50.079 -these are some of the positions in the - -00:13:50.079 --> 00:13:51.839 -tutorial that I found especially - -00:13:51.839 --> 00:13:53.920 -especially relevant this is a very dense - -00:13:53.920 --> 00:13:55.600 -tutorial I had to take notes of - -00:13:55.600 --> 00:13:56.480 -everything - -00:13:56.480 --> 00:13:59.040 -and I had to watch everything things - -00:13:59.040 --> 00:14:00.800 -several times - -00:14:00.800 --> 00:14:03.440 -and for example this is a link to the - -00:14:03.440 --> 00:14:06.480 -position in the tutorial that explains - -00:14:06.480 --> 00:14:09.600 -uh how in space - -00:14:09.600 --> 00:14:12.880 -space max magic magic - -00:14:12.880 --> 00:14:17.600 -interprets space gs magic status - -00:14:17.600 --> 00:14:20.480 -let's see beginners space gs to initiate - -00:14:20.480 --> 00:14:22.320 -magic's git status - -00:14:22.320 --> 00:14:25.600 -uh you can also do that's it - -00:14:25.600 --> 00:14:28.800 -and here are some examples that I - -00:14:28.800 --> 00:14:32.160 -took from somewhere else the video - -00:14:32.160 --> 00:14:34.240 -tutorials from - -00:14:34.240 --> 00:14:43.519 -ralph koenig about org mode - -00:14:43.519 --> 00:14:45.519 -now let me show how the functions that - -00:14:45.519 --> 00:14:47.440 -define this router hyperlinks are - -00:14:47.440 --> 00:14:48.720 -implemented - -00:14:48.720 --> 00:14:51.199 -the standard ways in max to define - -00:14:51.199 --> 00:14:52.480 -functions that define - -00:14:52.480 --> 00:14:55.760 -other functions would be with macros uh - -00:14:55.760 --> 00:14:58.320 -let's see an example this is a standard - -00:14:58.320 --> 00:14:59.040 -function that - -00:14:59.040 --> 00:15:01.540 -defines new functions - -00:15:01.540 --> 00:15:02.959 -[Music] - -00:15:02.959 --> 00:15:06.959 -and if we execute it one of the res - -00:15:06.959 --> 00:15:09.040 -its result is the last function that it - -00:15:09.040 --> 00:15:10.160 -defined which is - -00:15:10.160 --> 00:15:13.920 -e-grief which is here - -00:15:13.920 --> 00:15:16.959 -it's implemented as a macro we can - -00:15:16.959 --> 00:15:19.360 -look at the result of macro expand which - -00:15:19.360 --> 00:15:20.880 -is going to show - -00:15:20.880 --> 00:15:23.519 -show us the result of of this of the - -00:15:23.519 --> 00:15:25.519 -expansion of this - -00:15:25.519 --> 00:15:28.000 -instead of expanding and executing it - -00:15:28.000 --> 00:15:28.959 -just - -00:15:28.959 --> 00:15:33.199 -expands and shows us the result - -00:15:33.199 --> 00:15:36.000 -here the result is a bit messy is too - -00:15:36.000 --> 00:15:37.600 -big for - -00:15:37.600 --> 00:15:40.959 -humans to understand but we can run - -00:15:40.959 --> 00:15:44.240 -this or this text here that takes that - -00:15:44.240 --> 00:15:47.519 -that result and pretty prints it - -00:15:47.519 --> 00:15:50.959 -so this is the pretty printed version of - -00:15:50.959 --> 00:15:54.000 -uh this macro here - -00:15:54.000 --> 00:15:57.600 -we can see that it defines - -00:15:57.600 --> 00:16:01.120 -several functions here - -00:16:01.120 --> 00:16:06.399 -for example this one - -00:16:06.399 --> 00:16:09.360 -and this just as a curiosity is a link - -00:16:09.360 --> 00:16:09.920 -to - -00:16:09.920 --> 00:16:13.839 -the definition of cld struct - -00:16:13.839 --> 00:16:16.880 -and note that the code is huge uh - -00:16:16.880 --> 00:16:19.199 -well it's very well commented but it's - -00:16:19.199 --> 00:16:20.079 -it has - -00:16:20.079 --> 00:16:23.759 -lots of special cases it has uh - -00:16:23.759 --> 00:16:26.959 -it supports lots of constructions and so - -00:16:26.959 --> 00:16:27.920 -it's huge and - -00:16:27.920 --> 00:16:30.639 -it's very difficult to understand I mean - -00:16:30.639 --> 00:16:33.360 -I found it very difficult to understand - -00:16:33.360 --> 00:16:35.040 -and here's a link to document the - -00:16:35.040 --> 00:16:37.759 -documentation of cld struct - -00:16:37.759 --> 00:16:42.000 -here in the manual for - -00:16:42.000 --> 00:16:46.000 -cl which is a kind of support for some - -00:16:46.000 --> 00:16:50.480 -features of common lisp in the max - -00:16:50.480 --> 00:16:53.600 -so let's compare this standard way of - -00:16:53.600 --> 00:16:54.639 -defining - -00:16:54.639 --> 00:16:56.560 -functions that define new functions - -00:16:56.560 --> 00:16:58.320 -which is with macros - -00:16:58.320 --> 00:17:01.680 -with this I'm going to use a slogan - -00:17:01.680 --> 00:17:04.160 -repeatedly the slogan is I am a very bad - -00:17:04.160 --> 00:17:06.319 -programmer - -00:17:06.319 --> 00:17:08.880 -I'm a very bad programmer so when I was - -00:17:08.880 --> 00:17:10.640 -trying to create functions that would - -00:17:10.640 --> 00:17:12.240 -define new functions - -00:17:12.240 --> 00:17:14.480 -I found it easier to generally generate - -00:17:14.480 --> 00:17:16.400 -this code as text - -00:17:16.400 --> 00:17:20.559 -and then run read and eval in it - -00:17:20.559 --> 00:17:23.199 -the code cd that we saw in the previous - -00:17:23.199 --> 00:17:24.640 -section - -00:17:24.640 --> 00:17:28.079 -we can see the the code that it produces - -00:17:28.079 --> 00:17:29.039 -by - -00:17:29.039 --> 00:17:31.039 -making a copy of this line and - -00:17:31.039 --> 00:17:33.280 -prepending this string here to the name - -00:17:33.280 --> 00:17:34.480 -of the function - -00:17:34.480 --> 00:17:36.720 -so instead of running code cd we run - -00:17:36.720 --> 00:17:38.400 -find code cd - -00:17:38.400 --> 00:17:41.280 -and it creates a new temporary buffer - -00:17:41.280 --> 00:17:44.400 -with the code that - -00:17:44.400 --> 00:17:47.760 -code cd would execute - -00:17:47.760 --> 00:17:50.320 -so it's a series of the fonts and a few - -00:17:50.320 --> 00:17:54.080 -set cues and so on - -00:17:54.080 --> 00:17:57.600 -and this thing is implemented mostly as - -00:17:57.600 --> 00:17:59.120 -a template - -00:17:59.120 --> 00:18:02.160 -uh the lola the - -00:18:02.160 --> 00:18:04.160 -there's an inner function called ee - -00:18:04.160 --> 00:18:06.240 -called cd base that receives just - -00:18:06.240 --> 00:18:08.799 -these two arguments and it says - -00:18:08.799 --> 00:18:10.640 -essentially just runs the function - -00:18:10.640 --> 00:18:14.320 -e template zero on the string here and - -00:18:14.320 --> 00:18:16.480 -the things between curly braces are - -00:18:16.480 --> 00:18:18.559 -substituted by the values - -00:18:18.559 --> 00:18:23.600 -of these arguments here - -00:18:23.600 --> 00:18:25.919 -there's one part of the tutorial here - -00:18:25.919 --> 00:18:28.480 -that explains all these things - -00:18:28.480 --> 00:18:31.039 -uh except for the rationale for some - -00:18:31.039 --> 00:18:32.559 -design decisions - -00:18:32.559 --> 00:18:35.360 -and those design decisions are one of - -00:18:35.360 --> 00:18:37.280 -the many motivations for this talk but - -00:18:37.280 --> 00:18:37.760 -um - -00:18:37.760 --> 00:18:39.679 -we are I'm only going to explain these - -00:18:39.679 --> 00:18:42.640 -things in detail at the end - -00:18:42.640 --> 00:18:48.480 -which is kind of so on - -00:18:48.480 --> 00:18:50.320 -in the beginning I said that the three - -00:18:50.320 --> 00:18:51.600 -main keys of av - -00:18:51.600 --> 00:18:56.000 -are meta e meta k and meta j - -00:18:56.000 --> 00:19:00.080 -let's see now what met what meta j does - -00:19:00.080 --> 00:19:01.520 -uh but I need to start with some - -00:19:01.520 --> 00:19:04.640 -motivation uh the motivation is that we - -00:19:04.640 --> 00:19:06.559 -can define commands with very short - -00:19:06.559 --> 00:19:08.240 -names and actually I became kind of - -00:19:08.240 --> 00:19:10.160 -addicted to that - -00:19:10.160 --> 00:19:13.200 -this is an example of the fund that - -00:19:13.200 --> 00:19:15.600 -defines a comment with a very short name - -00:19:15.600 --> 00:19:18.000 -its name is just one letter e - -00:19:18.000 --> 00:19:21.200 -and I can invoke you invoke it with meta - -00:19:21.200 --> 00:19:21.520 -x - -00:19:21.520 --> 00:19:24.720 -e if I type meta xp - -00:19:24.720 --> 00:19:27.360 -now it opens a latex file that I'm - -00:19:27.360 --> 00:19:31.130 -working on - -00:19:31.130 --> 00:19:32.559 -[Music] - -00:19:32.559 --> 00:19:35.200 -and I create most of my latex files - -00:19:35.200 --> 00:19:37.120 -using - -00:19:37.120 --> 00:19:39.200 -template template-based functions like - -00:19:39.200 --> 00:19:40.559 -the the - -00:19:40.559 --> 00:19:43.760 -implementation of code cd above and - -00:19:43.760 --> 00:19:46.559 -this template-based functions create - -00:19:46.559 --> 00:19:49.280 -files with extension.tag - -00:19:49.280 --> 00:19:51.280 -that start with a series of the fonts - -00:19:51.280 --> 00:19:53.919 -and comments for example - -00:19:53.919 --> 00:19:56.240 -let's look at this example here if I - -00:19:56.240 --> 00:19:58.320 -execute find the attack links with this - -00:19:58.320 --> 00:19:59.440 -argument - -00:19:59.440 --> 00:20:02.159 -uh it's going it's going to do several - -00:20:02.159 --> 00:20:03.440 -things for creating a - -00:20:03.440 --> 00:20:06.880 -file called slash tmp slash forward - -00:20:06.880 --> 00:20:08.320 -attack - -00:20:08.320 --> 00:20:11.200 -and the header of that file is going to - -00:20:11.200 --> 00:20:12.400 -be this - -00:20:12.400 --> 00:20:16.080 -which starts with two and with three - -00:20:16.080 --> 00:20:19.280 -the fonts with functions with very short - -00:20:19.280 --> 00:20:21.919 -names and comments - -00:20:21.919 --> 00:20:27.520 -let's compare with the situation here - -00:20:27.520 --> 00:20:32.799 -in my file 2020 favorite conventions.tag - -00:20:32.799 --> 00:20:34.640 -I have this header here in which I - -00:20:34.640 --> 00:20:37.039 -define six functions with very short - -00:20:37.039 --> 00:20:39.360 -names - -00:20:39.360 --> 00:20:41.919 -and in this case here that is even - -00:20:41.919 --> 00:20:44.799 -explained in the tutorial - -00:20:44.799 --> 00:20:48.000 -this we have mnemonics for - -00:20:48.000 --> 00:20:51.520 -these short names here and c is compile - -00:20:51.520 --> 00:20:54.799 -d is display I mean display the pdf - -00:20:54.799 --> 00:20:57.760 -and e is added in the sense of make a - -00:20:57.760 --> 00:20:58.159 -max - -00:20:58.159 --> 00:21:02.320 -visit that file - -00:21:02.320 --> 00:21:05.039 -okay now I can explain what is meta j - -00:21:05.039 --> 00:21:06.480 -itself - -00:21:06.480 --> 00:21:08.880 -uh we just saw comments with very short - -00:21:08.880 --> 00:21:09.600 -names - -00:21:09.600 --> 00:21:12.320 -and the idea is behind meta j is that we - -00:21:12.320 --> 00:21:14.840 -can define comments with very short - -00:21:14.840 --> 00:21:16.480 -numbers - -00:21:16.480 --> 00:21:19.679 -let me explain this uh - -00:21:19.679 --> 00:21:22.559 -the short explanation for what meta j - -00:21:22.559 --> 00:21:23.039 -does - -00:21:23.039 --> 00:21:25.360 -is that it jumps to set certain - -00:21:25.360 --> 00:21:27.039 -predefined places - -00:21:27.039 --> 00:21:29.760 -in particular a meta j without a numeric - -00:21:29.760 --> 00:21:30.799 -argument - -00:21:30.799 --> 00:21:33.280 -takes us to a buffer with with the basic - -00:21:33.280 --> 00:21:34.080 -help - -00:21:34.080 --> 00:21:37.679 -and a list of the current age of targets - -00:21:37.679 --> 00:21:39.760 -and this is something that is a bit - -00:21:39.760 --> 00:21:41.520 -simpler to understand - -00:21:41.520 --> 00:21:44.559 -if we type meta five meta j - -00:21:44.559 --> 00:21:47.919 -then meta j runs this sex - -00:21:47.919 --> 00:21:51.120 -here that is associated to - -00:21:51.120 --> 00:21:55.440 -the argument five I say that the target - -00:21:55.440 --> 00:21:59.039 -for the argument five is this one - -00:21:59.039 --> 00:22:01.520 -and if the argument is true then the - -00:22:01.520 --> 00:22:03.760 -target associated to the to the true - -00:22:03.760 --> 00:22:07.039 -is this sex here that opens - -00:22:07.039 --> 00:22:09.600 -well this one opens the main tutorial vv - -00:22:09.600 --> 00:22:10.240 -and this one - -00:22:10.240 --> 00:22:13.679 -opens another tutorial - -00:22:13.679 --> 00:22:15.679 -this is a link to one of the tutorials - -00:22:15.679 --> 00:22:20.480 -of ev to the part that explains meta j - -00:22:20.480 --> 00:22:22.559 -I've copied the the main part of the - -00:22:22.559 --> 00:22:24.559 -text here - -00:22:24.559 --> 00:22:28.159 -the header the header that meta j shows - -00:22:28.159 --> 00:22:31.360 -let me show it very quickly here - -00:22:31.360 --> 00:22:33.919 -here is their header and here is their - -00:22:33.919 --> 00:22:36.320 -rest - -00:22:36.320 --> 00:22:39.039 -the header is very beginner friendly and - -00:22:39.039 --> 00:22:40.000 -if you're a beginner - -00:22:40.000 --> 00:22:42.159 -who only knows how to use meta e to - -00:22:42.159 --> 00:22:44.559 -execute and met - -00:22:44.559 --> 00:22:46.799 -this should be okay and meta k to go - -00:22:46.799 --> 00:22:48.240 -back - -00:22:48.240 --> 00:22:52.320 -then you can and should use that header - -00:22:52.320 --> 00:22:56.720 -I mean this header here - -00:22:56.720 --> 00:22:59.360 -as your main starting point and every - -00:22:59.360 --> 00:23:00.799 -time that you feel lost - -00:23:00.799 --> 00:23:03.679 -you can type meta j and to go back to - -00:23:03.679 --> 00:23:04.799 -that header - -00:23:04.799 --> 00:23:07.039 -and you can use its links to navigate to - -00:23:07.039 --> 00:23:08.000 -the documentation - -00:23:08.000 --> 00:23:11.360 -for max nav let me explain that - -00:23:11.360 --> 00:23:14.799 -uh this header here has several ellis - -00:23:14.799 --> 00:23:15.679 -hyperlinks - -00:23:15.679 --> 00:23:19.039 -one here one here - -00:23:19.039 --> 00:23:22.400 -one here one here and so on - -00:23:22.400 --> 00:23:25.760 -uh these ones are links to the - -00:23:25.760 --> 00:23:29.280 -to the intros which are the tutorials - -00:23:29.280 --> 00:23:30.880 -find if you quick enter in the main - -00:23:30.880 --> 00:23:32.480 -tutorial and find ev - -00:23:32.480 --> 00:23:35.760 -keys intro is a kind of tutorial that is - -00:23:35.760 --> 00:23:36.720 -an index of - -00:23:36.720 --> 00:23:40.000 -the main keys - -00:23:40.000 --> 00:23:42.559 -and after that we have an explanation of - -00:23:42.559 --> 00:23:43.279 -what some - -00:23:43.279 --> 00:23:46.799 -numeric prefixes do so if we type - -00:23:46.799 --> 00:23:50.240 -met one method j the effect of that is - -00:23:50.240 --> 00:23:53.200 -exactly the same as executing this and - -00:23:53.200 --> 00:23:54.640 -we can execute this - -00:23:54.640 --> 00:24:00.159 -with meta e also - -00:24:00.159 --> 00:24:03.679 -meta tube meta j runs this sex and - -00:24:03.679 --> 00:24:06.960 -I can also execute it with meta e - -00:24:06.960 --> 00:24:10.559 -here it is it's this uh - -00:24:10.559 --> 00:24:14.240 -intro this uh - -00:24:14.240 --> 00:24:18.400 -sandbox tutorial and - -00:24:18.400 --> 00:24:24.640 -here is another sandbox tutorial - -00:24:24.640 --> 00:24:27.039 -let me go back and then the - -00:24:27.039 --> 00:24:28.720 -documentation says that - -00:24:28.720 --> 00:24:30.880 -that header the header that is beginner - -00:24:30.880 --> 00:24:31.760 -friendly - -00:24:31.760 --> 00:24:33.679 -is followed by a section that is very - -00:24:33.679 --> 00:24:35.520 -beginner unfriendly - -00:24:35.520 --> 00:24:37.600 -that contains a series of the fonts like - -00:24:37.600 --> 00:24:40.400 -these ones - -00:24:40.400 --> 00:24:43.440 -here the last line of the header is this - -00:24:43.440 --> 00:24:44.640 -comment here - -00:24:44.640 --> 00:24:46.720 -and then we have several defense like - -00:24:46.720 --> 00:24:48.559 -this - -00:24:48.559 --> 00:24:51.440 -let me explain how these things work - -00:24:51.440 --> 00:24:53.840 -technically what happens when we type - -00:24:53.840 --> 00:24:57.360 -meta j without any arguments is that it - -00:24:57.360 --> 00:24:57.840 -runs - -00:24:57.840 --> 00:25:00.960 -eu jump with argument neil and then - -00:25:00.960 --> 00:25:04.640 -this runs 5 e jumps - -00:25:04.640 --> 00:25:06.480 -when I run meta j with a numeric - -00:25:06.480 --> 00:25:08.000 -argument for example - -00:25:08.000 --> 00:25:11.120 -with argument 5 it runs a jump - -00:25:11.120 --> 00:25:14.400 -5 and e jump five - -00:25:14.400 --> 00:25:17.679 -uh concatenates this five one - -00:25:17.679 --> 00:25:20.400 -to make a name of a function this - -00:25:20.400 --> 00:25:21.679 -function here - -00:25:21.679 --> 00:25:24.320 -and it executes this function e jump - -00:25:24.320 --> 00:25:24.720 -five - -00:25:24.720 --> 00:25:28.880 -you jump uh dash five - -00:25:28.880 --> 00:25:31.919 -and eu jump dash five is - -00:25:31.919 --> 00:25:35.520 -executes find ev equity intro - -00:25:35.520 --> 00:25:39.360 -if I execute just meta j - -00:25:39.360 --> 00:25:41.440 -the section that shows the current age - -00:25:41.440 --> 00:25:43.919 -on targets - -00:25:43.919 --> 00:25:47.120 -has a line for e job five this is that - -00:25:47.120 --> 00:25:48.159 -is exactly the - -00:25:48.159 --> 00:25:52.400 -thing that I was explaining before - -00:25:52.400 --> 00:25:54.840 -so we can use meta j to navigate the - -00:25:54.840 --> 00:25:59.520 -tutorials and we can copy the links - -00:25:59.520 --> 00:26:03.440 -sorry we can copy links to the to - -00:26:03.440 --> 00:26:07.919 -tutorials to our notes - -00:26:07.919 --> 00:26:11.840 -oh sorry this has some typos - -00:26:11.840 --> 00:26:14.880 -for example if I execute this - -00:26:14.880 --> 00:26:18.080 -I go to a section of this tutorial here - -00:26:18.080 --> 00:26:20.640 -that explains the main keys of ev - -00:26:20.640 --> 00:26:24.320 -and these things are hyperlinks I can - -00:26:24.320 --> 00:26:26.240 -mark a hyperlink like this it is just - -00:26:26.240 --> 00:26:27.440 -plain text and I - -00:26:27.440 --> 00:26:30.559 -can copy it to my notes and the idea is - -00:26:30.559 --> 00:26:31.760 -that every time - -00:26:31.760 --> 00:26:33.520 -every time that I find something that is - -00:26:33.520 --> 00:26:35.520 -interesting I can create a hyperlink to - -00:26:35.520 --> 00:26:36.240 -it - -00:26:36.240 --> 00:26:38.720 -and I can put these links in my notes so - -00:26:38.720 --> 00:26:40.799 -I can navigate back - -00:26:40.799 --> 00:26:42.960 -to all the interesting positions very - -00:26:42.960 --> 00:26:48.799 -quickly - -00:26:48.799 --> 00:26:51.760 -okay next feature if we type meta - -00:26:51.760 --> 00:26:54.080 -uppercase j - -00:26:54.080 --> 00:26:57.600 -uh then - -00:26:57.600 --> 00:27:00.080 -this this is a function that transforms - -00:27:00.080 --> 00:27:03.679 -the current line in a certain way - -00:27:03.679 --> 00:27:06.080 -let me give an example let me isolate - -00:27:06.080 --> 00:27:07.360 -this and let me create - -00:27:07.360 --> 00:27:09.919 -duplicate this line to to make clear - -00:27:09.919 --> 00:27:11.039 -what happens - -00:27:11.039 --> 00:27:14.240 -if I type meta uppercase j here - -00:27:14.240 --> 00:27:16.880 -this line here becomes the fund for a - -00:27:16.880 --> 00:27:17.440 -jump - -00:27:17.440 --> 00:27:21.200 -6 and the target of this e-jump - -00:27:21.200 --> 00:27:24.799 -is exactly this sex here - -00:27:24.799 --> 00:27:28.559 -let me undo this mess - -00:27:28.559 --> 00:27:31.360 -and if the first word in the line is not - -00:27:31.360 --> 00:27:32.840 -a number for example - -00:27:32.840 --> 00:27:36.240 -here let me do the same thing - -00:27:36.240 --> 00:27:39.039 -duplicate the line and type meta - -00:27:39.039 --> 00:27:41.200 -uppercase j - -00:27:41.200 --> 00:27:44.240 -then mat uppercase j converts that to a - -00:27:44.240 --> 00:27:45.600 -defund that defines - -00:27:45.600 --> 00:27:49.440 -a function with a very short name - -00:27:49.440 --> 00:27:52.720 -and this function with a very short name - -00:27:52.720 --> 00:27:56.720 -opens this file here in the directory - -00:27:56.720 --> 00:27:59.360 -with the copy of the the git repository - -00:27:59.360 --> 00:28:01.360 -for org mode - -00:28:01.360 --> 00:28:05.360 -let me undo the mass again - -00:28:05.360 --> 00:28:09.120 -oops - -00:28:09.120 --> 00:28:14.640 -that's it - -00:28:14.640 --> 00:28:17.760 -meta uppercase j is a - -00:28:17.760 --> 00:28:21.279 -particular case of of something that - -00:28:21.279 --> 00:28:24.559 -I use a lot in eevee I have if he has - -00:28:24.559 --> 00:28:25.279 -lots of - -00:28:25.279 --> 00:28:28.799 -comments that sorry key sequences - -00:28:28.799 --> 00:28:31.780 -that are like meta uppercase letter and - -00:28:31.780 --> 00:28:33.200 -[Music] - -00:28:33.200 --> 00:28:35.279 -almost all of them operate on the - -00:28:35.279 --> 00:28:37.279 -current line and transform the current - -00:28:37.279 --> 00:28:38.880 -line in certain way - -00:28:38.880 --> 00:28:42.000 -for example this is a file name - -00:28:42.000 --> 00:28:45.360 -and if I type meta uppercase f here - -00:28:45.360 --> 00:28:48.640 -it becomes a link to that file this is - -00:28:48.640 --> 00:28:50.000 -the name of a month page - -00:28:50.000 --> 00:28:53.600 -and if I type meta uppercase m here - -00:28:53.600 --> 00:28:55.760 -it converts that to the link to a month - -00:28:55.760 --> 00:28:58.080 -page and this is a shell command - -00:28:58.080 --> 00:29:01.679 -and if I type meta uppercase s here - -00:29:01.679 --> 00:29:04.960 -it converts that to a link to a - -00:29:04.960 --> 00:29:08.720 -to find fan shell - -00:29:08.720 --> 00:29:11.919 -and until a few years ago these - -00:29:11.919 --> 00:29:12.960 -functions - -00:29:12.960 --> 00:29:16.159 -with matter uppercase letter were half - -00:29:16.159 --> 00:29:18.080 -of my main ways of creating sex - -00:29:18.080 --> 00:29:18.880 -hyperlinks - -00:29:18.880 --> 00:29:21.039 -with few key strokes in the beginning of - -00:29:21.039 --> 00:29:22.399 -course I had to create my - -00:29:22.399 --> 00:29:25.600 -sex pipelines by typing each character - -00:29:25.600 --> 00:29:28.640 -but uh after some time and decided that - -00:29:28.640 --> 00:29:31.520 -I needed something more efficient - -00:29:31.520 --> 00:29:34.559 -so this is end of part one of the two of - -00:29:34.559 --> 00:29:34.960 -the - -00:29:34.960 --> 00:29:38.480 -presentation - -00:29:38.480 --> 00:29:40.640 -so this is part two of the presentation - -00:29:40.640 --> 00:29:41.760 -and the main theme - -00:29:41.760 --> 00:29:44.320 -here is the standard describe key - -00:29:44.320 --> 00:29:46.320 -function that comes with the max - -00:29:46.320 --> 00:29:49.200 -and my variant of it the thing is that - -00:29:49.200 --> 00:29:50.960 -the standard described key in max - -00:29:50.960 --> 00:29:53.120 -is user friendly but it is hacker - -00:29:53.120 --> 00:29:55.600 -unfriendly well I felt so - -00:29:55.600 --> 00:29:58.559 -and when I tried to complement it by by - -00:29:58.559 --> 00:30:00.799 -writing a hacker friendly version of it - -00:30:00.799 --> 00:30:03.120 -that produced the sex hyperlinks that I - -00:30:03.120 --> 00:30:03.919 -needed - -00:30:03.919 --> 00:30:05.440 -I got something that I found really - -00:30:05.440 --> 00:30:07.039 -lovely and - -00:30:07.039 --> 00:30:09.679 -several of the main designs design - -00:30:09.679 --> 00:30:12.480 -decisions of eev can be seen there - -00:30:12.480 --> 00:30:14.320 -but when I showed my variants to other - -00:30:14.320 --> 00:30:15.520 -people they hated it - -00:30:15.520 --> 00:30:17.760 -they felt that it was totally against - -00:30:17.760 --> 00:30:19.360 -their notions of - -00:30:19.360 --> 00:30:23.440 -user friendliness - -00:30:23.440 --> 00:30:25.760 -okay so let's see the standard describe - -00:30:25.760 --> 00:30:26.799 -key if I run - -00:30:26.799 --> 00:30:30.159 -this hyperlink here I get - -00:30:30.159 --> 00:30:32.399 -this the result of running the scribe - -00:30:32.399 --> 00:30:34.399 -key on the key down - -00:30:34.399 --> 00:30:36.399 -and this is a big buffer with some - -00:30:36.399 --> 00:30:38.080 -things in italics - -00:30:38.080 --> 00:30:41.360 -and some hyperlinks here these - -00:30:41.360 --> 00:30:43.120 -hyperlinks are standard in the sense - -00:30:43.120 --> 00:30:43.679 -that - -00:30:43.679 --> 00:30:46.240 -the targets are not visible and they are - -00:30:46.240 --> 00:30:47.760 -implemented using - -00:30:47.760 --> 00:30:50.799 -buttons in a max lisp this section of - -00:30:50.799 --> 00:30:51.200 -the - -00:30:51.200 --> 00:30:53.919 -mx list manual describes how buttons - -00:30:53.919 --> 00:30:56.799 -work - -00:30:56.799 --> 00:31:00.640 -and the the source code is - -00:31:00.640 --> 00:31:03.440 -quite difficult I mean when I was - -00:31:03.440 --> 00:31:04.240 -starting to - -00:31:04.240 --> 00:31:06.559 -to try to decipher this when I was a - -00:31:06.559 --> 00:31:07.600 -beginner - -00:31:07.600 --> 00:31:11.200 -using max 19.34 I felt that this - -00:31:11.200 --> 00:31:12.320 -described key was - -00:31:12.320 --> 00:31:15.519 -very difficult to understand uh - -00:31:15.519 --> 00:31:20.080 -and I felt that the the designers the - -00:31:20.080 --> 00:31:22.640 -the people who wrote it were sacrificing - -00:31:22.640 --> 00:31:23.679 -too much of the - -00:31:23.679 --> 00:31:26.159 -hacker friendliness that I was expecting - -00:31:26.159 --> 00:31:31.279 -from it to make it beginner friendly - -00:31:31.279 --> 00:31:33.600 -let me explain what are the the problems - -00:31:33.600 --> 00:31:34.799 -with the standard - -00:31:34.799 --> 00:31:36.559 -the describe key if we think that - -00:31:36.559 --> 00:31:38.640 -hyperlinks are things like this - -00:31:38.640 --> 00:31:41.600 -with the target and the text then in the - -00:31:41.600 --> 00:31:43.600 -button hyperlinks of describe key - -00:31:43.600 --> 00:31:47.120 -this three bad things happen first - -00:31:47.120 --> 00:31:49.120 -it is hard to extract the target from - -00:31:49.120 --> 00:31:51.200 -the hyperlink second it is hard to - -00:31:51.200 --> 00:31:52.000 -recreate - -00:31:52.000 --> 00:31:54.480 -a list of code that would go to that - -00:31:54.480 --> 00:31:55.440 -target - -00:31:55.440 --> 00:31:57.519 -and third it is hard to copy the full - -00:31:57.519 --> 00:31:59.840 -hyperlink including the targets to other - -00:31:59.840 --> 00:32:00.640 -buffers - -00:32:00.640 --> 00:32:04.960 -I only knew how to copy the text - -00:32:04.960 --> 00:32:07.279 -when I was trying to decipher what - -00:32:07.279 --> 00:32:09.039 -described key was doing - -00:32:09.039 --> 00:32:11.679 -I created lots of hyperlinks like this - -00:32:11.679 --> 00:32:12.159 -to - -00:32:12.159 --> 00:32:14.960 -inspect the text properties and things - -00:32:14.960 --> 00:32:16.159 -like that - -00:32:16.159 --> 00:32:18.480 -for example in the description of the - -00:32:18.480 --> 00:32:20.000 -key down - -00:32:20.000 --> 00:32:23.600 -here we have a button that points to - -00:32:23.600 --> 00:32:26.799 -simple dotel - -00:32:26.799 --> 00:32:29.679 -the text of that button is simple.l this - -00:32:29.679 --> 00:32:31.600 -hyperlinks goes to the - -00:32:31.600 --> 00:32:34.320 -to the middle of this button hyperlink - -00:32:34.320 --> 00:32:35.519 -here - -00:32:35.519 --> 00:32:39.120 -uh this hyperlink here - -00:32:39.120 --> 00:32:41.919 -goes to the middle of the button of this - -00:32:41.919 --> 00:32:43.279 -button hyperlink - -00:32:43.279 --> 00:32:46.240 -and then inspects its text properties - -00:32:46.240 --> 00:32:47.679 -and then goes to - -00:32:47.679 --> 00:32:51.679 -this section here of the description - -00:32:51.679 --> 00:32:53.679 -so this is a high level description of - -00:32:53.679 --> 00:32:56.159 -the text properties - -00:32:56.159 --> 00:32:58.000 -I mean the text properties that make it - -00:32:58.000 --> 00:33:00.000 -a button and this is a - -00:33:00.000 --> 00:33:02.480 -lower level description of the these - -00:33:02.480 --> 00:33:04.320 -text properties - -00:33:04.320 --> 00:33:08.000 -and the button that points to - -00:33:08.000 --> 00:33:11.440 -forward line sorry the the button that - -00:33:11.440 --> 00:33:11.919 -whose - -00:33:11.919 --> 00:33:14.399 -text is forward line this one is - -00:33:14.399 --> 00:33:16.480 -slightly different - -00:33:16.480 --> 00:33:19.039 -this hyperlink here goes to the middle - -00:33:19.039 --> 00:33:21.200 -of that button - -00:33:21.200 --> 00:33:24.559 -and this hyperlink goes to the mid to - -00:33:24.559 --> 00:33:25.760 -the middle of that button - -00:33:25.760 --> 00:33:28.559 -inspects its text properties and go to - -00:33:28.559 --> 00:33:29.360 -the section - -00:33:29.360 --> 00:33:32.559 -of this button of this help - -00:33:32.559 --> 00:33:35.760 -uh buffer here that describe the the - -00:33:35.760 --> 00:33:36.399 -button - -00:33:36.399 --> 00:33:39.120 -and the lower level view of the text - -00:33:39.120 --> 00:33:41.679 -properties - -00:33:41.679 --> 00:33:45.519 -so I started to with things like this - -00:33:45.519 --> 00:33:47.519 -to understand what these buttons were - -00:33:47.519 --> 00:33:50.159 -doing and I was able to figure out how - -00:33:50.159 --> 00:33:50.960 -these things are - -00:33:50.960 --> 00:33:53.120 -implemented and describe key and then - -00:33:53.120 --> 00:33:55.519 -similar help functions in max - -00:33:55.519 --> 00:33:57.760 -and I discovered that one of the main - -00:33:57.760 --> 00:34:00.000 -lower level functions that a max used - -00:34:00.000 --> 00:34:01.360 -for this - -00:34:01.360 --> 00:34:04.080 -is a function called find function no - -00:34:04.080 --> 00:34:05.279 -select - -00:34:05.279 --> 00:34:08.240 -if I run find function no select on next - -00:34:08.240 --> 00:34:09.929 -line - -00:34:09.929 --> 00:34:11.200 -[Music] - -00:34:11.200 --> 00:34:14.240 -it returns a pair - -00:34:14.240 --> 00:34:18.079 -a cons made of a buffer and a position - -00:34:18.079 --> 00:34:20.560 -so I created functions that would that - -00:34:20.560 --> 00:34:21.679 -would - -00:34:21.679 --> 00:34:24.320 -uh follow this that would open that - -00:34:24.320 --> 00:34:25.119 -buffer - -00:34:25.119 --> 00:34:28.320 -in that position and then this is a - -00:34:28.320 --> 00:34:29.679 -postback list - -00:34:29.679 --> 00:34:31.679 -so we could go to these positions and - -00:34:31.679 --> 00:34:33.919 -then search for this string and another - -00:34:33.919 --> 00:34:36.000 -string and another string and so on - -00:34:36.000 --> 00:34:40.320 -so this goes to the definition of find a - -00:34:40.320 --> 00:34:41.040 -function - -00:34:41.040 --> 00:34:44.159 -and then to a to a string - -00:34:44.159 --> 00:34:47.919 -after it and I use these things to - -00:34:47.919 --> 00:34:49.040 -implement my own - -00:34:49.040 --> 00:34:51.839 -functions that pointed to the same the - -00:34:51.839 --> 00:34:52.960 -same targets - -00:34:52.960 --> 00:34:55.440 -as the button hyperlinks and describe - -00:34:55.440 --> 00:35:00.240 -key - -00:35:00.240 --> 00:35:03.200 -again let me show the comparison this is - -00:35:03.200 --> 00:35:05.599 -the standard describe key - -00:35:05.599 --> 00:35:10.480 -here and this is my variant - -00:35:10.480 --> 00:35:13.839 -uh it creates a buffer with links - -00:35:13.839 --> 00:35:17.680 -with the list hyperlinks about this key - -00:35:17.680 --> 00:35:20.960 -we get this so each one of these - -00:35:20.960 --> 00:35:22.960 -functions is either a blank line - -00:35:22.960 --> 00:35:28.720 -or a or an ellipse hyperlink - -00:35:28.720 --> 00:35:31.760 -here is a slight variant of the of the - -00:35:31.760 --> 00:35:32.880 -function - -00:35:32.880 --> 00:35:35.920 -find e key links above in this variant - -00:35:35.920 --> 00:35:38.079 -the argument is a string that has to be - -00:35:38.079 --> 00:35:39.280 -processed by - -00:35:39.280 --> 00:35:42.400 -read cbd macro to convert it to the - -00:35:42.400 --> 00:35:45.280 -lower level format - -00:35:45.280 --> 00:35:48.160 -and note that these functions here that - -00:35:48.160 --> 00:35:49.040 -I wrote - -00:35:49.040 --> 00:35:51.440 -they display temporary buffers with no - -00:35:51.440 --> 00:35:53.599 -help at all - -00:35:53.599 --> 00:35:57.359 -uh to be honest there's a link to a - -00:35:57.359 --> 00:35:58.560 -tutorial here but - -00:35:58.560 --> 00:36:01.680 -this is a recent edition so let's ignore - -00:36:01.680 --> 00:36:03.200 -this - -00:36:03.200 --> 00:36:06.640 -uh they they display temporary buffers - -00:36:06.640 --> 00:36:08.320 -with no help at all just lots of - -00:36:08.320 --> 00:36:09.520 -hyperlinks - -00:36:09.520 --> 00:36:11.599 -and these hyperlinks can be they are - -00:36:11.599 --> 00:36:13.359 -very hacker friendly in the sense that - -00:36:13.359 --> 00:36:15.040 -they can be followed with - -00:36:15.040 --> 00:36:17.520 -metae they can be copied to other - -00:36:17.520 --> 00:36:19.920 -buffers because they are plain text - -00:36:19.920 --> 00:36:23.680 -because they are just sex - -00:36:23.680 --> 00:36:26.240 -and they can be inspected in the sense - -00:36:26.240 --> 00:36:28.000 -that - -00:36:28.000 --> 00:36:32.400 -for example here - -00:36:32.400 --> 00:36:34.079 -we have a hyperlink to a function that - -00:36:34.079 --> 00:36:35.520 -we - -00:36:35.520 --> 00:36:37.599 -it may be difficult to figure out what - -00:36:37.599 --> 00:36:39.200 -this function does - -00:36:39.200 --> 00:36:42.320 -but we can go to that position and then - -00:36:42.320 --> 00:36:45.839 -type ctrl h f to see the descript - -00:36:45.839 --> 00:36:48.240 -description of this function - -00:36:48.240 --> 00:36:52.400 -and here is a hyperlink to - -00:36:52.400 --> 00:36:53.890 -the does that - -00:36:53.890 --> 00:36:56.000 -[Music] - -00:36:56.000 --> 00:37:00.160 -in my syntax say - -00:37:00.160 --> 00:37:02.800 -and this list of hyperlinks were - -00:37:02.800 --> 00:37:04.480 -generated by - -00:37:04.480 --> 00:37:08.000 -this code here that just just uh - -00:37:08.000 --> 00:37:11.119 -used a back quote to to generate - -00:37:11.119 --> 00:37:14.640 -lists of sex - -00:37:14.640 --> 00:37:18.240 -and I I felt that this function here - -00:37:18.240 --> 00:37:21.040 -uh that just generated this list was - -00:37:21.040 --> 00:37:22.160 -very easy to understand - -00:37:22.160 --> 00:37:24.960 -and to modify so this was hacker - -00:37:24.960 --> 00:37:28.480 -friendly in the way that I wanted - -00:37:28.480 --> 00:37:31.599 -and so I started using this - -00:37:31.599 --> 00:37:34.079 -and this idea of using buffers with sex - -00:37:34.079 --> 00:37:36.800 -fiber links and no help violated - -00:37:36.800 --> 00:37:38.720 -all the notions of user friendliness - -00:37:38.720 --> 00:37:40.079 -that I knew so I was - -00:37:40.079 --> 00:37:42.000 -exploring some something new at that - -00:37:42.000 --> 00:37:46.160 -time and this is the end of part two - -00:37:46.160 --> 00:37:49.359 -part three of this presentation is uh - -00:37:49.359 --> 00:37:52.240 -about the killer features of ev or why - -00:37:52.240 --> 00:37:54.800 -everybody should use av or at least have - -00:37:54.800 --> 00:37:57.920 -eev installed even if they think the tv - -00:37:57.920 --> 00:37:59.280 -is too weird - -00:37:59.280 --> 00:38:01.440 -so this is a very quick listing eevee - -00:38:01.440 --> 00:38:03.440 -has lease hyperlinks which are super - -00:38:03.440 --> 00:38:04.240 -nice - -00:38:04.240 --> 00:38:06.560 -it comes with lots of tutorials the main - -00:38:06.560 --> 00:38:07.599 -one here - -00:38:07.599 --> 00:38:10.800 -explains all the main features - -00:38:10.800 --> 00:38:14.079 -uh there's also a tutorial with that's - -00:38:14.079 --> 00:38:15.040 -an index of - -00:38:15.040 --> 00:38:18.079 -all the other tutorials here - -00:38:18.079 --> 00:38:21.680 -many many many tutorials uh if we forget - -00:38:21.680 --> 00:38:24.079 -everything we can just type meta j - -00:38:24.079 --> 00:38:27.280 -and remember that this this part here is - -00:38:27.280 --> 00:38:28.880 -beginner friendly and the rest is - -00:38:28.880 --> 00:38:30.839 -beginner - -00:38:30.839 --> 00:38:32.960 -unfriendly - -00:38:32.960 --> 00:38:38.320 -there's a tutorial on max list here - -00:38:38.320 --> 00:38:41.920 -it mainly explains how to understand - -00:38:41.920 --> 00:38:44.640 -a lisp code which is much easier than - -00:38:44.640 --> 00:38:46.320 -it's much easier to understand the lisp - -00:38:46.320 --> 00:38:47.040 -code and - -00:38:47.040 --> 00:38:48.800 -then to understand how to program in a - -00:38:48.800 --> 00:38:50.160 -lisp and - -00:38:50.160 --> 00:38:53.440 -most people are only going to need this - -00:38:53.440 --> 00:38:55.920 -uh ev is very easy to install it's in - -00:38:55.920 --> 00:38:58.240 -helper so we just need to do - -00:38:58.240 --> 00:39:00.560 -this thing here and it's very - -00:39:00.560 --> 00:39:03.520 -non-invasive - -00:39:03.520 --> 00:39:06.079 -uh years ago several years ago it was a - -00:39:06.079 --> 00:39:08.000 -very invasive package but then I changed - -00:39:08.000 --> 00:39:08.960 -everything - -00:39:08.960 --> 00:39:13.520 -now uh if we toggle ev mode on and off - -00:39:13.520 --> 00:39:16.640 -what's going to happen is just that the - -00:39:16.640 --> 00:39:20.000 -evk map key map becomes activated or - -00:39:20.000 --> 00:39:21.599 -deactivated - -00:39:21.599 --> 00:39:24.720 -and when we install the evita - -00:39:24.720 --> 00:39:28.320 -I mean when we require the only things - -00:39:28.320 --> 00:39:28.640 -that - -00:39:28.640 --> 00:39:32.640 -happens globally distance here - -00:39:32.640 --> 00:39:34.480 -several functions and variables become - -00:39:34.480 --> 00:39:36.240 -defined all of them have - -00:39:36.240 --> 00:39:40.079 -standard prefixes except for one - -00:39:40.079 --> 00:39:43.040 -three characters are changed in the - -00:39:43.040 --> 00:39:44.480 -standard display table - -00:39:44.480 --> 00:39:48.640 -to make them appear as colored glyphs - -00:39:48.640 --> 00:39:52.079 -the red star and two and the open - -00:39:52.079 --> 00:39:54.160 -double angle brackets and the closed - -00:39:54.160 --> 00:39:58.160 -double angle brackets - -00:39:58.160 --> 00:40:01.359 -and two environment variables are set - -00:40:01.359 --> 00:40:04.560 -and this is a trivial technicality - -00:40:04.560 --> 00:40:07.599 -we just run a def advice - -00:40:07.599 --> 00:40:10.160 -around one function that that is used by - -00:40:10.160 --> 00:40:10.800 -man - -00:40:10.800 --> 00:40:14.240 -justice also - -00:40:14.240 --> 00:40:16.720 -eevee has a very high discoverability - -00:40:16.720 --> 00:40:18.400 -factor - -00:40:18.400 --> 00:40:21.839 -and there's a way to create a very easy - -00:40:21.839 --> 00:40:25.200 -way to create a hyperlink to here - -00:40:25.200 --> 00:40:27.760 -uh I do not have time to show this now - -00:40:27.760 --> 00:40:29.760 -but for example if I'm - -00:40:29.760 --> 00:40:32.960 -here in a tutorial and I think that that - -00:40:32.960 --> 00:40:34.480 -this - -00:40:34.480 --> 00:40:36.240 -section is something interesting and I - -00:40:36.240 --> 00:40:39.520 -want to create a hyperlink to it - -00:40:39.520 --> 00:40:41.200 -I just have to type a certain key - -00:40:41.200 --> 00:40:43.040 -sequence here - -00:40:43.040 --> 00:40:46.800 -and here I got a hyperlink that I can - -00:40:46.800 --> 00:40:50.400 -copy to my notes and this hyperlink goes - -00:40:50.400 --> 00:40:52.260 -to that section - -00:40:52.260 --> 00:40:58.240 -[Music] - -00:40:58.240 --> 00:41:00.720 -we have hyperlinks that point to - -00:41:00.720 --> 00:41:02.319 -specific positions in - -00:41:02.319 --> 00:41:05.839 -pdf documents and nvidia files here - -00:41:05.839 --> 00:41:09.119 -this one opens a pdf and displays it - -00:41:09.119 --> 00:41:09.680 -this one - -00:41:09.680 --> 00:41:13.920 -opens a pdf and converts it to text - -00:41:13.920 --> 00:41:16.720 -and this one opens the video in a - -00:41:16.720 --> 00:41:18.400 -certain position - -00:41:18.400 --> 00:41:20.480 -and we also have a way to control - -00:41:20.480 --> 00:41:22.079 -shell-like programs - -00:41:22.079 --> 00:41:25.280 -uh in my presentation of the last year I - -00:41:25.280 --> 00:41:27.440 -spent one third of the presentation - -00:41:27.440 --> 00:41:29.520 -explaining this and I think that I gave - -00:41:29.520 --> 00:41:31.839 -a very good demonstration there - -00:41:31.839 --> 00:41:35.680 -the demonstration is here - -00:41:35.680 --> 00:41:38.800 -we can go to the web page and go to - -00:41:38.800 --> 00:41:41.839 -this section of the web page - -00:41:41.839 --> 00:41:47.680 -and start by this point - -00:41:47.680 --> 00:41:51.440 -and here we have an explanation and so - -00:41:51.440 --> 00:41:55.920 -on whatever - -00:41:55.920 --> 00:41:58.720 -and I've already mentioned this before - -00:41:58.720 --> 00:41:59.200 -uh - -00:41:59.200 --> 00:42:01.119 -eevee comes with a very nice elise - -00:42:01.119 --> 00:42:02.240 -tutorial - -00:42:02.240 --> 00:42:04.240 -so that's it this is the end of part - -00:42:04.240 --> 00:42:05.599 -three - -00:42:05.599 --> 00:42:07.359 -so this is the last part of my - -00:42:07.359 --> 00:42:09.839 -presentation and it's about the title of - -00:42:09.839 --> 00:42:10.160 -the - -00:42:10.160 --> 00:42:11.839 -the presentation I called the - -00:42:11.839 --> 00:42:13.599 -presentation why - -00:42:13.599 --> 00:42:16.560 -most of the best features in eevee look - -00:42:16.560 --> 00:42:16.960 -like - -00:42:16.960 --> 00:42:20.480 -like five minute hacks uh I've already - -00:42:20.480 --> 00:42:20.960 -run off - -00:42:20.960 --> 00:42:23.920 -out of time so I have to to skip this - -00:42:23.920 --> 00:42:24.800 -first - -00:42:24.800 --> 00:42:28.720 -part here in which I describe how I - -00:42:28.720 --> 00:42:31.280 -was exposed to several different notions - -00:42:31.280 --> 00:42:33.440 -of user friendliness - -00:42:33.440 --> 00:42:35.920 -and how the one that really blew my mind - -00:42:35.920 --> 00:42:37.119 -was the one in - -00:42:37.119 --> 00:42:41.680 -in a certain uh fought environment - -00:42:41.680 --> 00:42:44.160 -uh and let me make the long long story - -00:42:44.160 --> 00:42:46.560 -very very short - -00:42:46.560 --> 00:42:49.280 -uh in all this process I switched from - -00:42:49.280 --> 00:42:49.680 -from - -00:42:49.680 --> 00:42:52.079 -the belief that the user was always - -00:42:52.079 --> 00:42:52.960 -someone else - -00:42:52.960 --> 00:42:55.359 -someone external and that that I always - -00:42:55.359 --> 00:42:57.040 -had to write my programs for - -00:42:57.040 --> 00:43:00.079 -this external user I switched - -00:43:00.079 --> 00:43:02.240 -from from that to the belief that I am - -00:43:02.240 --> 00:43:03.200 -the user - -00:43:03.200 --> 00:43:05.839 -and I can play with the interface that I - -00:43:05.839 --> 00:43:07.040 -want I can - -00:43:07.040 --> 00:43:10.079 -write programs which that - -00:43:10.079 --> 00:43:12.079 -that only I am going to understand I can - -00:43:12.079 --> 00:43:14.240 -experiment with hundreds of interfaces - -00:43:14.240 --> 00:43:16.079 -and then select the best ones - -00:43:16.079 --> 00:43:18.720 -and document them and then share them - -00:43:18.720 --> 00:43:20.960 -with other people - -00:43:20.960 --> 00:43:23.520 -who are also experimenting with - -00:43:23.520 --> 00:43:24.720 -interfaces in their - -00:43:24.720 --> 00:43:28.880 -own ways and so eevee has - -00:43:28.880 --> 00:43:31.119 -lots of things that are user-friendly in - -00:43:31.119 --> 00:43:33.440 -these unusual ways that I've explained - -00:43:33.440 --> 00:43:34.880 -before - -00:43:34.880 --> 00:43:37.760 -and uh and if we disconsider that this - -00:43:37.760 --> 00:43:40.319 -notion of user friendliness is valid - -00:43:40.319 --> 00:43:44.079 -then this implement these things that av - -00:43:44.079 --> 00:43:45.119 -implement they are - -00:43:45.119 --> 00:43:47.280 -user friendly and hacker friendly at the - -00:43:47.280 --> 00:43:48.800 -same time - -00:43:48.800 --> 00:43:51.119 -and let me show one example this is one - -00:43:51.119 --> 00:43:51.920 -this is - -00:43:51.920 --> 00:43:54.640 -one that really took me one only five - -00:43:54.640 --> 00:43:56.640 -minutes to implement - -00:43:56.640 --> 00:43:59.599 -uh at one point a few months ago I - -00:43:59.599 --> 00:44:00.640 -discovered - -00:44:00.640 --> 00:44:04.240 -that sasha chewer's weekly posts about - -00:44:04.240 --> 00:44:05.599 -the max news - -00:44:05.599 --> 00:44:08.800 -had uh were also being posted to a - -00:44:08.800 --> 00:44:11.440 -mailing list that is stored at - -00:44:11.440 --> 00:44:14.800 -lists.we know.org and it's called max - -00:44:14.800 --> 00:44:16.319 -dungeons - -00:44:16.319 --> 00:44:19.280 -uh and I just and I found a way to - -00:44:19.280 --> 00:44:19.760 -create - -00:44:19.760 --> 00:44:25.440 -the links to to the posts in both places - -00:44:25.440 --> 00:44:28.400 -but I had to use a template for that so - -00:44:28.400 --> 00:44:30.640 -what we are seeing here now - -00:44:30.640 --> 00:44:32.560 -is a template with the the default - -00:44:32.560 --> 00:44:36.640 -values so this means that we have not uh - -00:44:36.640 --> 00:44:39.359 -set the year correctly we have not set - -00:44:39.359 --> 00:44:40.720 -the month correctly - -00:44:40.720 --> 00:44:44.240 -or the day correctly but if we run this - -00:44:44.240 --> 00:44:44.720 -text - -00:44:44.720 --> 00:44:48.960 -here uh let me do something else before - -00:44:48.960 --> 00:44:53.359 -if we run this text here - -00:44:53.359 --> 00:44:57.280 -which we change some of these - -00:44:57.280 --> 00:45:00.880 -entries in the - -00:45:00.880 --> 00:45:04.400 -in the template and we get these links - -00:45:04.400 --> 00:45:05.200 -here - -00:45:05.200 --> 00:45:09.119 -they all work for example this one opens - -00:45:09.119 --> 00:45:12.160 -uh the blog post in in session sasha - -00:45:12.160 --> 00:45:12.800 -chewers - -00:45:12.800 --> 00:45:16.000 -site and this one - -00:45:16.000 --> 00:45:21.280 -opens it in the mailing list - -00:45:21.280 --> 00:45:23.440 -and sometimes I want the org source of - -00:45:23.440 --> 00:45:25.760 -that and the easiest way to get the word - -00:45:25.760 --> 00:45:27.280 -source is to - -00:45:27.280 --> 00:45:30.480 -look at this link here that has an - -00:45:30.480 --> 00:45:31.680 -attachment - -00:45:31.680 --> 00:45:35.040 -and if I take this - -00:45:35.040 --> 00:45:38.560 -link here and I take this - -00:45:38.560 --> 00:45:42.319 -stem that points to to the attachment - -00:45:42.319 --> 00:45:44.480 -and I put it here and I generate this -
