Leo Vivier: Okay, well, thank you. I'm -in. So you've just had a little roundup of the news, and we're going -to get started now with some presentations. We're starting with user -developer stories. I was extremely interested in this section because -I wanted to get a chance, basically, to tell you a little more about -who I am and how I got from basically being a user of Emacs to being -nowadays a package maintainer, and maybe more in the future. I don't -know. - -So, just for the organizers, I'm planning to speak for 15 minutes, and -I'll have five more minutes of questions at the end. As I told you -before, if you want to have questions, you know you can use the pad, -and I'll be reading the questions from there. Okay. - -So hi there, as Amin introduced me before, my name is Leo Vivier. I'm -a freelance software engineer in France, and I have been using Emacs -now for i believe close to eight years. I can't believe it's been so -long. But yes, it's been a journey because, in a way, nothing made me -go for Emacs. You know I'm an-- sorry, I was about to say Emacs major, -but no, I'm an English major. I went to university to study English -literature and linguistics, and I just got started in Emacs because I -was looking for ways to take better notes. I was looking for ways to -[Applause] structure the way I was learning, structure the way I was -taking notes. I stumbled one day upon this weird piece of software -which was called Emacs, and I've been trapped forever since, -basically, because eight years ago, when I discovered Emacs I just -couldn't let go. There was just something very interesting about the -way you configured your setup, and I just wanted to dive deeper and -deeper. - -So the title is of this talk exactly is how I went from user to -package maintainer, and the package now that I'm maintaining is called -org-roam. I'm not the only one doing this. I'm helped with many lovely -people working on org-roam. I got started as a maintainer only this -year, so that means that for the eight years I've been an Emacs user, -seven of those years were spent merely being a user trying to be a -sponge for knowledge, trying to learn as much as I could. I believe it -would be interesting for me to share my story because I believe that -I'm far from being the only user who can make the jump to being a -maintainer. - -A lot of you have a lot of knowledge when it comes to Emacs. Some of -you are at different steps in your journey. Some of you, for instance, -are just starting to copy stuff out of StackExchange into your Emacs -configuration. let's say you want to do something very particular and -you haven't found a way to do so. You go on StackExchange. You find -something that's interesting. You add it to your Emacs configuration. -You barely understand anything that's going on. You know that it's -supposed to be Emacs Lisp. "I hardly know Emacs and I know even less -what is Lisp supposed to be." But you paste it in and it does what you -want it to do, and you say "Great, I'll move on to my work now." So -that's how I got started. I had a very spartan setup for Emacs, which -a lot of you must know... The first time you launch Emacs, you have -this feeling that you're jumping 20 years back in time, as far as the -user interface is concerned. But as you get to spend more time with -Emacs... Some would call it Stockholm syndrome insofar as you can't -see how spartan the entire thing is, but it actually is a lovely -prison so to speak. - -That's how I got started eight years ago. I just wanted to find a way -to do my research properly. I wanted to have a tool that I could use -to write my notes in plain text, because I was already fairly averse -to Microsoft solutions when it came to taking notes. So yeah, I got -started in Emacs. I read a little bit about what plain text was about. -Just to be clear, at the time, yes, I was very good with computers, -but I was not a computer science student. I had barely any experience -with programming and coding, and I was even less of a hacker back -then. It just goes to show you that at the beginning, I had close to -no knowledge, whether it be about the free software world, whether it -be about... - -Sacha, do you want to say something? (Sacha: just confirming, you're -not sharing anything on the screen at the moment, right?) No, I'm not -sharing anything, I'm just presenting. - -So when I started, I had no experience whatsoever. I was just a -literature major trying to get better at taking notes. I stumbled upon -LaTeX. As many people who stumble upon LaTeX know, you don't just -stumble upon LaTeX, you embroil yourself in the turmoil of suffering, -of late nights tweaking, so that your document is exactly in the -perfect shape you want it to be. - -Soon after, when I got started with Emacs and LaTeX, I discovered -something that truly changed my life, and it was Org Mode. As you'll -get a lot of presentations this afternoon about Org Mode, I won't be -spending too much time on it. But Org Mode, for me, was a revelation. -It's... There was something that, upon reading articles on how to use -Org Mode, especially one of the key article that I'd read which really -made a huge impact on me was the "Organize Your Life in Plain Text" -one which i'm sure many of you must have stumbled upon in your Emacs -journey... For me, when I stumbled upon this document, I was starting -to get interested in Getting Things Done and all the nitty-gritty -stuff about organization and self-organization. It just felt like -everything was under my fingertips to make the perfect workflow. There -was something incredibly satisfying about having a system that gave -you so many options to configure your experience exactly how you -wanted. You had this feeling that the people behind Org Mode had -thought of everything, whichever small adjustment that you needed in -workflow whether it be more states for your TODOs, whether it be, oh, -I want my weeks to start on Monday and not on Saturday, oh, it's half -past one and I need to... in the morning, I mean, and I need to make -sure that the item that i'm marking as done is done for the day before -and not for the current day. You see what I'm talking about. So many -details that were already present in Org Mode. At first you're really -impressed, because you think, wow, they thought of everything, but -then you realize that it's just a matter of experience, just a matter -of people contributing code, because the development of Org Mode, -Emacs, and everything is just open to the public. - -You know, it's like everything is being done with the garage -door opened. You can just go on Org Mode on Savannah and see -everything that is being developed. For me, the shift that occurred in -my mind was when I was reading all the options, I was looking at all -the variables that i could modify for Org Mode, and there came a time, -maybe two to three years ago, where I thought, oh wow, maybe for the -first time in a while, there is no option for me to do what I want to -be doing with Org Mode. I believe at the time the the key issue that -triggered this reflex for me was I wanted to do something with the -agenda. I wanted to have a super category so, you know, in the... for -those of you who know, in your agenda, you have the ability to have -many files, and you have the ability to have categories. I wanted -somehow to group my TODOs in smaller groups, or bigger groups, I -should say, so that, for instance, I could have one group for my -professional life, I could have a group for one work, the second -work... I could have something for university and all this. I thought, -yeah, I think I'd like this. After having spent so long working with -Emacs and working with Org Mode, I had some ideas about what was -within the realm of possibility and what wasn't. Here I thought to -myself, this is definitely something that I can do. And so thus -started my journey into the Org Mode libraries. - -I won't go too much into details right now, because right now, the -main objective that I have is just to show you how simple it is to -become a maintainer, how to become more involved with the development. -The libraries in Org Mode, they're written in Elisp, which is a -very... It might seem like an obscure language, and it certainly is, -but as soon as you get the logic of the language--and what i'm telling -you is coming from someone who's never studied programming-- it made -sense. Everything is so verbose when you get into the code. When you -learn the rudiments of Elisp, you start getting to the code, and you -start thinking, wow, okay that makes sense, and you start developing a -logic for all this. So, equipped as I was with this new knowledge, I -went on my project, i went into the Org agenda code, and I thought, -okay, is there anything that I can use to do my bidding? Fast forward -maybe two to three weeks of intense turmoil and many nights which were -spent single-mindedly working on this project, two weeks after, I had -something that was working, and I was pretty happy about it. That was -a key landmark for me, because when that happened, it just felt like, -okay, I can contribute something to Org Mode, and I can do something -that would benefit as many people as possible. And to me, that was the -click. That's when it occurred. That's when I went on my first project -and I did something that felt useful to the community. - -And nowadays, as I told you, I maintain packages, but really, nothing -has changed. The only thing, maybe, that has changed that I've turned -my mind onto other problems. Maybe I've got three more minutes and I'd -like to finish by maybe something a little different. - -I've told you my Emacs story and I hope I've stressed how little -effort it took me to move from steps to steps on the ladder. The -ladder implies a sense of hierarchy, but it really isn't. Whatever -your step on the journey of Emacs is... Some of you might be at the -step where you're really worried about learning Elisp because it feels -like such a monumental task to be undertaking and you have no -experience whatsoever, but the thing is, maybe you could try climbing -this first step on the ladder. Maybe you could try, if you have any -project, if you've been using Org Mode, maybe one day you thought, -"oh, yes, I wish I could do this but I can't," or maybe do try to do -this, maybe do try to change something in a major mode that you're -using and which you feel might be better. I think Emacs, Org Mode, and -all free software in general has this tendency to give you this idea -that I can be a hacker in the sense of the term that you're modifying -things to do your bidding. For me, I believe this to be a very healthy -attitude towards software. As Amin said in the very beginning, we are -doing this entire presentation-- sorry, this entire conference with -free software. Just see all the things we've been able to do in free -software. For me, Emacs was my gateway, so to speak, into how to -contribute to free software, about the philosophy that surrounds it. - -What I would like to do... I'll finish on this note and then I'll be -taking your questions. Just try. You've read on Reddit that you need -to go through the Elisp manual in Emacs. You might be scared, but just -do it. Just give it a shot. Just give it maybe one afternoon. Try to -read it. Try to see if this appeals to your mind. If you've been -interested enough in my presentation right now, and if you're -interested enough in any of the talks you're going to have during the -entire conference, do give it a shot. I'm pretty sure you will like -the journey on which you will be embarking upon. So - -I believe I'm finishing one minute early, but I see quite a bit of -questions already. I'm not sure. Sacha, should I just be reading the -questions, or do you want to be feeding me the questions? (Amin: It's -really up to you. it's completely up to you. If you've got the -questions open and can take them or read them, by all means please.) -Okay, well, I'm going to read them because I've got them on the side. -I'm going to start with the one at the bottom. - -"Do you feel that being a white male contributed to your experience?" -Yeah. I mean, I do believe... There's an idea of privilege. I mean, -I'm French. I live in... I'm lucky enough to be here at university, -okay, and I'm fairly aware of the discrepancies that happen, even in -France, according to this... So, yes, I believe my journey was heavily -influenced by this. If you would like to specify the question, please -do, but I don't have really all that much to ask on this. - -"What is your advice to start learning Elisp language? Any -particularly good resource or any other tips?" I finished um my -presentation by telling you about the Elisp introduction which is -built into Emacs. What I might do... I'm going to share my screen just -to show you how this works. I will be sharing this window. I believe -it's frozen on my end, so I can't see anything. i'm not sure if you -can see me or if my camera is moving. Okay, so my Firefox is frozen. -So i'll answer the question, but I won't be able to show you what I -wanted to show you. There's a built-in guide inside Emacs to learn -Elisp. Maybe the best chance that you have is just to go open these -info pages. I'm sure someone will be kind enough to mention this to -you in the #emacsconf channel on IRC but it's probably the best way to -get started with Elisp. You know, we tend to get obsessed, with -software and with programming, about what's the best way to get -started. You see so many people who are heavily interested in getting -started with programming but they never managed to get started because -there's so much choice. My advice would be to just get started. Don't -get so worried about the first step. Well, if I may still recommend -the first step, even after saying this, do try to start with the -built-in guides. I believe they're pretty pretty good. - -There was another question. It's the last question that I can read and -after that, you will have to read the questions for me because -everything is frozen on my end. I hope I'm not frozen in a very bad -position so please excuse me if my mouth is open or anything. (Amin: -no, we just completely lost the video feed, so no worries.) Oh, -splendid, so I won't have to make a fool out of myself. - -So the last question I wanted to answer was "Have you read Dirk -Gently's Holistic Detective Agency?" No, I haven't. I hope it's not a -jab at the way i'm dressing for the conference, but yeah, I haven't -read it. Was there any other question? - -(Amin: I see one other question. "Any recommendation for good -packaging guides or places to start? i get a bit overwhelmed by some -things. For example, the choice of different test frameworks.") Right. -Okay. So that's a very good question. I believe alphapapa is in the -chat right now. As myself a new lisp developer for org-roam, i'd -really recommend you to look into his package developers' guide -because you have a list of all the softwares that are extremely useful -to be using when you're getting started. If you're looking into a -first step for how to develop elast package, i'd really advise you to -look into edebug. It's one word, edebug, and you have a section in the -manual for this, because for me, it was the key step to getting to -develop good packages. It was understanding basically what the code -did and having us something like a REPL (read-evaluate-print-loop) -that allows you to step through the code and see exactly which states -the variables are at which at this point in the program. That's really -my biggest advice to you. Any other question? Thanks. Yeah, I -see one or two more. So there's one. - -They ask, "How did the freedom of Emacs help you on your way?" So the -freedom of Emacs... I mentioned that Emacs, for me, was my gateway -into free software and the freedom of Emacs was that you could -maybe... First and foremost, compared to other software, was that you -had behind Emacs, Elisp, which allows you to read the code, read -whatever is going on in the background. Surely, if you go deep enough, -you'll end up on C functions that you might not be able to read if you -do not have the experience. But for Org Mode, which was my gateway -into Emacs, most of it is written in Elisp, and all the commands have -a very verbose name, like something simple as org go to next subtree -or org go to a parent subtree. You know, things like this. It's so -elegant. It's verbose. That's a sense of freedom insofar as you can go -into the code and see, oh, okay, that's how it's implemented. I -believe in a way that's the freedom and the liberty that is given to -you to look into the code is something that invites you to do the same -with your life. As someone who does a little bit of philosophy on the -side, I believe it's a very healthy message to be gathering from a -piece of software. - -(Amin: Awesome, thank you. Let's see... So we have... I think I saw -another question pop up.) I'm not sure how we're doing as far as time -is concerned... I believe we have like one or two minutes more. (Amin: -Yeah, actually, we're quite a bit ahead of the schedule, so if we take -a little bit longer, we're fine. If you do have more questions, please -do.) I'm just sorry that my video is not working anymore. (Amin: No -problem. Someone was actually saying... What's the most recent... -Actually, yeah well before that. - -"Please show off your three-piece suit before you end your talk, which -requires fixing your frozen camera. if this is not possible, please -post suit selfies in an easily accessible location." Okay, I'll make -sure to do this. But yes, I wanted to hype things up for the -conference, so yes, I did get the three-piece suit out. I'm very glad -you like it. By the way when you get a chance to see me live again, do -appreciate that my tie has both the colors of Emacs purple and also -Org Mode green. It took me a while to find this one, so I hope you -will appreciate this. - -(Amin: Awesome. Let's see. We have one other question. "What's the -most recent Emacs package or tool that you've discovered that you've -added to your repertoire?") Very interesting question. The thing is, -when you've spent as long as I have on Emacs--and I know that I've -only spent eight years and some of you might have spent maybe 10, 20, -maybe even more years on Emacs-- but for me, I believe the the coolest -neat trick that I found in Emacs was a mode which is called -beacon-mode. It's something that allows you to show when you're -jumping between buffers or when you're dropping between windows, it -shows exactly where your point is in that buffer by making a slight -ray of light which looks like a beacon, hence the name. It really -helps you navigate buffers because it always shows in a very visual -way where your point is. I'll get a chance to show this to you later -today when i'll be presenting my other talks. - -(Amin: AWesome. We have one question from Jonas, the maintainer from -Magit. He asks, "When you touched your webcam, that blew a fuse at my -place. How did you do that?") Well, I'm very sorry, Jonas, that it -happened to you, but i'll make sure not to touch my webcam again. -(Amin: Do we have any other questions?) I have to trust you on this -one. I'm really sorry. Everything is frozen on my end. (Amin: No -problem.) - -Yeah I'm more talking to the audience, I guess. I hope my lack of -slides didn't bother you. I really wanted to have this verbose time -with people, to be able to... it's a message that i've been trying to -share with as many people as possible. In france we do have an Emacs -workshop that we have on a monthly basis. I've been learning a lot -with those people and I felt like doing the same with Emacs conference -would be good. That's why i'm really happy, and I'm really lucky to -have had the chance to do this today. I hope some of you I've -convinced you of climbing up a step on a ladder or making a step in a -journey. (Amin: Absolutely. Thank you so much, Leo. I happen to -completely agree with your not necessarily using a slide when it's not -really needed and to help give some face-to-face time with the -audience. Unfortunately your webcam cut out, but I mean before that.) -Yes, I'll make sure to fix the problems later on, so don't worry about -it. (Amin: Awesome. Alrighty. I guess we're wrapping up for your talk -and getting ready for the next talk.) Sure. Well, thank you so much. -I'll see you all later, I suppose! (Amin: Sounds good. Thank you -again, Leo.

I am Jonathan. In this -talk, I'm going to demonstrate ways of producing sheet music in Emacs -using Lilypond, and maybe also convince you to use Emacs for writing -your scores. I'll start with an overview of the syntax for those who -are new to using text-based notation as a shallow dive into the deep -pond of lilies and Lilypond, and move on to showcase some of its -functionalities using Org Mode and lilypond-mode. One disclaimer, -however: I am not a Lilypond developer. - -(00:40) So what is Lilypond? Lilypond is a file format and music engraving -system for producing high-quality sheet music. It translates textual -representations of music to graphical objects. It's similar to LaTeX -in that its input format describes the visual layouts of the score, -using commands to define musical expressions. Commands begin with a -backslash. For example, the formatter command, as shown on the left, -yields its graphical equivalents on the right, the fermata symbol over -the low B and so on and so forth. It's also fully extensible, like -Emacs, allowing users to extend and override Lilypond's -functionalities using the Scheme scripting language. It can be used -for early and contemporary music tablature, vocal music lead sheets, -and so on. Above all, it works with Emacs. In fact, Lilypond ships -with Emacs Lisp libraries, including a major mode for editing Lilypond -files. - -(01:47) So the input files are similar to source files. They contain -expressions formed with curly braces, comments that start with the -percent sign, and the code is indented. Notes are entered using -lowercase letters, and rests with the letter r. In this case, the -lowercase r or r4 is the equivalence of a crotchet or quarter note -rest. Durations are entered using numbers and dots after the note -name. If you do not specify one, the previous duration is used. You -can also tie notes together using the tilde symbol (~). In fact, you -can input chords, lyrics, embellishments, and a lot more. I encourage -you to read the manual for more information. Now let's switch to a -terminal window. With Lilypond installed, let's create a test file -with the extension .ly and open it in Emacs. - -(02:50) At the top of the file is the version statement, which tells Lilypond -which version to use when compiling the file. Here I'm using version -2.20.0. I've added the clef and time signature. Let's add some notes. -I'm going to close this now and compile the file by running lilypond -followed by the file name. So now let's view the output. Okay. - -(03:27) So here's a more complex example for randomizing note sequences. The -idea is to create new reading materials each time the code blocks are -evaluated. As usual, we begin with a header. I've added the title and -composer. Then we add the note sequences to use in the composition. In -this case, sn is a note name just like a b c d and so on, and stands -for snare drum, the percussion instruments. Now here's a function -that's going to shuffle the notes in the table. Finally, we expand the -notes inside the Lilypond source block. So whatever the function -returns is expanded inside the drums block. Now let's press C-c C-c to -view the results. Okay. And if I run this again, it should create a -new composition. Great. You can also audition a piece using the midi -command, which creates a midi file of the score. - -(04:34) Note also that the ob library-- sorry, the ob-lilypond library comes -with two modes. The one I'm using now is called arrange mode and is -useful for assembling complete scores. The basic mode on the other -hand allows you to mix text and music by embedding Lilypond snippets -and export them using typical Org Mode commands. - -(05:00) Now to demonstrate the basic mode in action. I'm going to export this -document to a PDF file. In this case, the :file header argument is -required, so you have to provide one and include the file name. Again, -you can run the code and view the results. Here it is. So now let's -export this to a PDF file. And here it is, what it generates. - -(05:39) Now I'm going to show you the workflow I used to produce music books -in Emacs, combining Lilypond and LaTeX for a perfect marriage. I begin -by sketching the first draft of the manuscript using pencil and paper. -Then I move to Emacs to input the notes in a git repository. This is a -typical source file. It begins with a stylesheet where I set variables -and layout settings, although in general, there's no need for tweaking -the layout unless you have specific requirements to do so. The easiest -way to compile the file from Emacs is by pressing C-c C-l, so let's do -this now, and the compilation buffer will tell you if there were any -errors in the file. Now to automate the process of compiling several -files and building the PDF, I use GNU Make, so all I have to do is -open the shell and run the make command. Don't worry, I'll provide a -link to the source code on the last slide. - -(06:41) As I moved forward with the project, I found at least two things -missing. One, I had no access to a metronome, at least not from the -editor, so I built one for casual use and made it available in the -MELPA repository. I also missed bar numbers in the source file. This -is useful when going back and forth between input and output files -without getting lost. So I wrote a command for toggling bar numbers, -which I hope you can see on the left. Also, some expressions are -difficult or slow to write on the keyboard-- accents and tuplets, for -example--so I use template expansion extensively for this purpose, -mainly yasnippet. - -(07:23) So what do I think? Well, I think Lilypond can be a -sharp paradigm shift for people used to GUI alternatives, but the -results are impressive. You don't have to dive too deeply to start -using Lilypond. Likewise, the ability to extend the software, I think, -is especially appealing for music professionals, enthusiasts, -composers, and the academic community: for example, allowing users to -create alternative notation systems required in non-Western music -traditions and other non-conventional requirements. Also, Lilypond and -Emacs both have extensive and well-written manuals and active -communities of users. But if you're still not sure where to start and -when to wedge your feet in the deep but warm pond of lilies, Lilypond, -and Lilypond users, I invite you to contribute to my Lilypond -projects, which you can do so from the links on the screen. So, thank -you all. I look forward to your comments, and I hope you enjoy the -rest of the conference. - -<!-- /transcript --> +[[!template new="1" text="Hello, everyone, and welcome to the EmacsConf." start="00:00:02.000" video="mainVideo" id=subtitle]] +[[!template text="I am Jonathan.

This is my talk titled Bard -Bivou(m)acs: Publishing Music with Emacs. I'm a software developer -with Unabridged Software in Lincoln, Nebraska. Long time Emacs user, -relatively new Emacs hacker. Hopefully, I'll be able to show you my -workflow, with how I publish music with Emacs. All right. - -(<a href="#mainVideo" class="time-link">00:30</a>) -So as a musician, I would like to publish my music online. I could -publish with popular online music services, but I'm more of a -DIY-type, so I chose to go ahead and publish with Emacs. What's the -motivation behind this? A lot of it comes down to some fundamental -freedoms that Emacs and GNU software represent to me, as well as my -ideas on culture and my background. I don't believe that music is a -consumer good. It's a form of knowledge, like an algorithm. And it's -just such a part of culture, like in tribal cultures, music was seen -as a gift from the cosmos or the gods. It was a gift maybe through an -individual vessel, but was shared with the people and shared with -everyone, kept alive by the culture itself. So to me, music is -something that should be shared and should be freely enjoyed by -everyone. Of course, artists should be compensated as well, but that's -a whole different topic. - -(<a href="#mainVideo" class="time-link" data-timestamp="99">01:39</a>) -So when I want to share my music, I want to do it without -impacting anyone's freedom. Using GNU software like Emacs is a good -way that I can ensure that I won't be requiring people to sign away -their freedoms for anything. There's a lot more I could say about this -but I don't have time. Feel free to reach out to me by email or IRC. -Part of the motivation for me, personally, is that Emacs is super -magical. It's an all-in-one solution. Like I said, the GNU software -aligns with Creative Commons' ideas. I can do file management. I can -author HTML, all the web stuff I need even, literate-style. I can -handle media and metadata. I've got version control, remote server -access... All the tools I need are right under my fingertips with this -tool that I use every day for a long time. I don't need to look -elsewhere. - -(<a href="#mainVideo" class="time-link">02:31</a>) -It was a challenge. I wanted to see if I could do this all -within Emacs itself. So, how do you use Emacs to publish music? Well, -for me, I needed a couple of things. I needed to be able to audition -and label unlabeled audio tracks. I have a lot of files that I don't -know where they came from. I don't know what they are. I need to be -able to listen to them, and I need to be able to add metadata to -whatever audio format it is and rename the files based on that -metadata, potentially. And in the end, I wanted to take those files -and programmatically produce a web page for people to consume. - -(<a href="#mainVideo" class="time-link">03:08</a>) -I found out that Emacs scores a hundred percent on all of -these requirements that I had for this, and a lot of that came from -EMMS, the Emacs multimedia system. EMMS is great. If you haven't -checked it out, please do. It's a little bit unintuitive, but once you -get into it, you know it works. Basically, what EMMS gave me was the -ability to listen to the tracks, organize playlists. On top of that, -it gave me super-powered metadata authoring. - -(<a href="#mainVideo" class="time-link">03:42</a>) -I'm going to demonstrate that to you. So in order to do this, -you have to require markable playlists, so (require 'emms-mark). I'm -going to go through, and I'm going to open the red... I've got this. -These files here. So you can see these files are mp3s. They're -recorded on a digital recorder. If I had the choice, I would have a -recorder that used a different format, but so be it. I can mark all -these files and I can do EMMS add to .., and now they've been loaded -into a playlist. So you can see the playlist here. There's some -leftover files. - -(<a href="#mainVideo" class="time-link">04:30</a>) -So I've got these three files in my playlist, and as -you can see, it's just the file name, the path. I don't have any -metadata associated with them. In this playlist, I can hit E, and -it'll bring up a buffer showing the tag information that I have. I -could edit these here. I could edit them one at a time, but that's not -really great. I want superpower metadata authoring. So, by marking -them, I can then hit E, and I have all three of the tracks loaded up -in this tags buffer. On top of that, I can do EMMS tag editor, set -all, C-c C-r, and I want to set the artist. so these are some -recordings of my family. So, Shangreaux, set all three of them. I want -to set the album: Spring Walk with Lap Harp. I want to set the year. -And then I'm going to go ahead and put these in manually, but with the -power of Emacs keyboard macros and registers and so on. I could do -this programmatically as well, which would make it a lot easier if I -had much more than three files to do this with. Submit the changes -with C-c C-c, and now we've got the playlist. You can see the artist -and track number have been updated here. - -(<a href="#mainVideo" class="time-link">6:15</a>) -And then the final piece of this is that if you look at this, -you can see that the file name is still the same. So if I were looking -at the directory, I would still have this file name. When packaging -these up for a release, for people to download, it's nice to be able -to have that filename reflect the track number and the artist and so -on. So there's another command, EMMS rename tag editor, rename, so it -could be just capital R. I think I need to mark all of these, hit -capital R, and then it's going to ask me to confirm and say yes to all -of them. And now, if you look in the-- whoops I have to update -it--you'll see it's been updated with the artist, track number and -track name. This format is a format string, so it's customizable of -course. I just decided to go with the default. - -(<a href="#mainVideo" class="time-link">7:21</a>) -So that's pretty great, this workflow just with EMMS. I didn't -have to do anything. This is all there. It's all built in. It gave me -exactly what I was looking for in terms of being able to process a lot -of raw audio files add metadata to them and get them ready for -publishing. And this is for publishing for playback in any media -player. It'll be useful. Not just for the web page that I'm building. - -(<a href="#mainVideo" class="time-link">7:48</a>) -So the final part, of course, is to build the web page. Emacs -makes authoring HTML trivial. As I was going through this, I wanted to -challenge myself and just be, like, can I do this just all with Emacs? -Can I just make this? I don't need a... I don't need Ruby. I don't -need Rails. I don't need Node. I don't need any of this other stuff. I -have my tool right here. It's a fully... It's a whole operating -system, basically, plus programming languages. So the first thing I -started with was buffer scripting for manipulating text. That's kind -of the easiest way to do it. Basically, anything you can do in a -buffer, you can do programmatically with Elisp. So this might be a -good example for beginners. If you haven't done any Elisp yet, a -simple example is to create this this div output here. You can use -this with-temp-buffer, so basically creating an imaginary buffer. -insert is just like typing, so you put strings in, you put new lines -in, you can build some strings together. Here you can see I'm doing a -random number, so every time I execute this, my content change. I -can generate dynamic content in HTML blocks with Elisp. - -(<a href="#mainVideo" class="time-link">9:04</a>) -For my web page builder, It's a little more complex. I'm -pulling data out using EMMS data structures, so it's pulling that out -from the track data. And then I'm using some program to generate list -elements, so each track is going to have the title and track number, -and then a button for playing it, plus the source of the audio file, -which will get added here. Right now, this is hard coded for Opus, so -it won't work for my MP3s. I'm going to skip over snippets. Turns out -format strings were good enough for me. Snippets could be useful, but -format is super powerful, and I didn't really even need all that much -power, basically, just doing string interpolation. So if you haven't -seen format before, you basically put these control strings or control -characters inside of a string, and you can generate an output string -that you want. So in my generator code, basically, it's down here, I'm -calling format with this Bard Bivou(m)acs template, and that's -basically a big a big string of HTML. It's just my whole page of HTML -with those control characters in just four places. One of them -populates the track list. That's really the meat of the program. -Again, this is a combination of using buffer scripting, using HTML -mode, inserting text format strings, and then I can indent-region so -the HTML actually looks pretty when it comes out of it as well. I will -show that, just really quick actually. So you can see, this is the -HTML that got generated. I've got my template. I inserted the title -here, the style, the font was all inserted, and then this whole list -of of tracks here. It's kind of messy to look at, but this track list, -this whole div here, is all generated by my generator code, and it -works. It's great. Okay, moving on. - -(<a href="#mainVideo" class="time-link">11:27</a>) -So the other thing was that as I was developing this, I -decided to use Org Babel and some of his its features for -multi-language things because I needed to style it with CSS and and -put actions in Javascript, and also I used SVG for authoring stuff. It -was a little bit complicated. It probably would have been simpler had -I not used Org Babel, but it's also really fun. I think it's a cool, -cool idea to use literate programming. My idea was to create HTML -components. I could name it like this, put a format string inside it, -and build a function in Elisp to format it and spit out the HTML that -I want. By doing this, then, I can just change things in my Org file -which, not getting a whole lot of time to work on it, I can come back -to it and I have a lot of notes. I can kind of generate things as I'm -going and keep notes for myself, and keep the... I don't know. It's -cool. Literate programming is fun. So I don't need to go into that too -much, but you can see if I execute this here, I get the the div that I -want. It's a little bit funny. You'll see I have the string like this, -the way that noweb expands, I can't do this on a single line. It looks -funny when you do that, so that might be something to work out later. -CSS blocks can either be tangled out and referenced in the HTML source -or inlined. Here's an example I have of inlining it. So I've got my -little CSS block named style, Javascript named script, and then I've -got this HTML source block with noweb expansion. These double angle -brackets here are where I'm going to expand the block named style. I'm -actually calling a function, so I want the result of the function -here, and then the script will just get expanded here. So -org-babel-expand-src-block, you can see what it looks like. I've got -my style here. I've got my title. I've got that main content class I -showed before, and the script as well. So that's kind of cool. I could -just run org-babel-tangle and get my thing out and just edit one file -instead of multiple files. Not for everyone, but I thought it was kind -of fun. All right. - -(<a href="#mainVideo" class="time-link">13:45</a>) -Oh, and the final thing is that in Emacs, you can author and -view SVG. So this is just an Org. This SVG, I used to make the play -and pause buttons. I didn't know this, but if you edit an SVG file, -you can toggle back and forth between the code and the image. It's -pretty sweet. So I can iteratively work through this because of how -Emacs is. - -(<a href="#mainVideo" class="time-link">14:20</a>) -Final considerations here, like when doing this, I want it to -be all free, so I want to use fonts that use a free license. I found -GNU Unifont. It's kind of cool. The content license... I chose -Creative Commons Attribution ShareAlike, which is kind of like the -GPL. Ideally, I could serve it with Emacs. I'd like to remove -idiosyncrasy so other people can use it. It's pretty much just my tool -right now. Not requiring the web browser... I can ship playlists so -that you can just click or link to a playlist on your favorite player, -even EMMS if you want, and then packing up those albums in like a ZIP -or .tar file. - -(<a href="#mainVideo" class="time-link">15:04</a>) -So you can go to churls.world . It just has a link to this -album. I'll display it here in just a second. You can contact me. I'm -shoshin on #emacs in IRC and on sourcehut. You can email me -grant@churls.world, personal, or grant@unabridgedsoftware.com. All -right, now. Let's see about this... This is up online, so if you want -to listen to my college band's album from 20 years ago, here it is: -Casiopeia Basement Days. Whoops. I made this art in Krita. You can -press play. You can skip around. I do have the playlist up here too. -So yeah, thanks for listening. I hope you enjoyed it, and enjoy the -rest of EmacsConf.

Good question. In -one version of my talk, I spent too long explaining it, and decided to -cut it out. It's basically a bad pun on band camp. A bivouac--I don't -even know if I'm pronouncing that correctly--it's like a tent or a -camp that you put up hastily, and a bard is a musician, of course. -Yeah, I don't know. I like puns. I'm a dad. That's the best I could -come up with. I'll probably find a different name for it but I liked -that "bivoaucs," if you stick an m in there, it becomes Bivou(m)acs. -It's kind of like editor macros for generating some HTML. Yes, it is -confusing, chatting on IRC at the same time. Great question. (Amin: -Grant, so right now, you're sharing your screen. Are you planning on -showing something with it, or for example, should I maximize you?) I -don't know. I can turn it off for now. Okay. (Amin: You can turn on -the webcam.) Yeah, okay. (Amin: I'll maximize your webcam.) Okay, -thanks. I'll get to the answer for my color theme here in a bit in -IRC. - -(<a href="#qnaVideo" class="time-link">1:31</a>) -Next question on the Etherpad, does this metadata workflow also -support unsynchronized lyrics within ID3 tags, multi-line metadata? I -don't know, actually. It's funny because I was trying out different -things with metadata, and really the biggest thing was to figure out -how to do mass tag editing. And that was like... It wasn't very -intuitive, like I said, with EMMS. I think EMMS is really great, but -its interface is huge. like if you do M-x and type emms, you get I -don't know, 270-some candidates. There's a lot of functions going on. -I basically found the features that I needed to get this workflow -working. I would guess that you probably can do it, and if you don't, -if you can't do it out of the box, I think you could script EMMS to do -that. I'd like to know more, and I'm certainly going to be -investigating it. I will try and post my findings somewhere online. - -(<a href="#qnaVideo" class="time-link">2:39</a>) -Is it possible to import batch metadata? I'm not sure. I would -guess yes is the answer. EMMS can connect to metadata services. I -haven't done that because I was just using audio files that I created -myself. I know that on the back end, it calls out to shell programs -for tagging things. there's a lot of different options that can shell -out too. I was using the the vorbis tools to tag the particular files -I was working with. You can also use tiny tag, and there's some -other... That might be the python library. I can't remember. There's -two other libraries that I can shell out to for doing metadata. - -(<a href="#qnaVideo" class="time-link">3:24</a>) -My current workflow for tagging music is to first apply replay -gain in fubar 2000, fix egregious mistakes, use beats to apply -metadata from music brains, or discogs, go over remaining albums with -fubar 2000 again. Is there a chance textual tagging could allow doing -it all in one program? Have I experimented with mass tag update -queries? I have not. Again, I was just doing this workflow, taking raw -files with no tags and doing that. I believe because it calls out to -the programs in the back end, I'm sure you could work that out. I -think EMMS would benefit from having something like that because we -work with text, and being able to use Emacs as a front end for those -updates would be really fantastic. So really, it's just a matter of -writing the interface to the external tool. - -(<a href="#qnaVideo" class="time-link">4:22</a>) -Is there a link to some info expanding philosophy of how to -compensate musicians? No, I don't really have a lot of philosophy -around that. I guess the first thing I could say would be something -like a universal income. I feel like that would solve a lot of -problems, if musicians could just be musicians and not have to worry -about their pay. I will think about it more. This is one of my first -forays into getting public with some of these ideas, so I will try to -do more and let the community know. - -(<a href="#qnaVideo" class="time-link">4:54</a>) -What Emacs theme am I using? Can't remember. It's one of the -Kaolin themes. I think it was Aurora or or Bubble Gum, maybe, but the -Kaolin themes are nice. I recommend them. Not using Doom Emacs, Doom -mode line though. It's very pretty. - -(<a href="#qnaVideo" class="time-link">5:17</a>) -SVG support built into Emacs? I'm using Emacs 27.1, and yes, -SVG support is built in. I may have had to compile it with some Cairo -support. I don't remember for sure. But yes, you can even take -screenshots of your Emacs from within Emacs in SVG. It's pretty great. -I don't know how much more time we have left for questions. That's -most of the things on the etherpad. (Amin: I think we have like 10 -more minutes to catch up with the schedule. If there are more -questions, feel free to answer them.) I'll start looking through IRC. -(Amin: And keep an eye on the pad too.) Thank you all for listening -and for enjoying the talk. I'm glad it turned out well. Awesome. Yeah, -it's been fun so far. How did I manage? I can post a snippet of that, -or actually I can share my screen, can't I... Okay. I actually have it -up right here. - -(<a href="#qnaVideo" class="time-link">6:49</a>) -So I think I got this from alphapapa, to be honest. I define -screenshot-svg. It's an interactive command. Oh yeah, there's -alphae.papa Okay, there we go. I would like to change this so that I -can get it into the copy-paste buffer so I don't have to copy the file -in, but I haven't really hacked on it yet. - -(<a href="#qnaVideo" class="time-link">7:20</a>) -Okay, org heading colors. That might be a good question. I know, the -presentation... Sorry, it's hard to think and type at the same time. -Think and talk and type. - -(<a href="#qnaVideo" class="time-link">7:41</a>) -So the presentation is just a normal org file, right, so I have my -headers, and the author--you can even stick your email and other -headers in there. But there's a package called org-tree-slide. Whoops, -why is it not... I must have not required it. Good question. (Amin: -Grant, can you try sharing your screen maybe?) Oh, is it not shared? -I'm sorry. (Amin: Thank you.) There we go, should be coming up. (Amin: -It's coming up. Yep, we see it.) Awesome. All right. Okay. I don't -know why this isn't working. It was working. Okay, you want to see the -screenshot. Whoops. Okay, I just took a screenshot. So, org-tree-slide. -I don't know why it's not launching. I thought that I had required it, -but I must not have. Maybe I'll try. Okay. So there we go. So -org-tree-slide is a way that basically uses narrowing and some kind of -font tricks to... it changes your titles or your metadata into this -banner for the title here, and it automatically sets the faces for -you. You can customize that, of course. And then, as you go through -the Org file, you get these kind of nice animations and-- what's it -called--breadcrumbs up at the top. So org-tree-slide. I highly -recommend it. It's really nice because you can give your presentation -and practice it, and while you're practicing it, you can edit things -as well, because it's still just an Org document using narrowing, you -know. It doesn't actually change anything. Definitely recommend -org-tree-slide mode. Okay, let's see, what else... - -(<a href="#qnaVideo" class="time-link">10:29</a>) -Share my screen to demo. Oh, that's the SVG. Let's see. Okay, so I -don't know if you can see this now, but I'm actually viewing the SVG -screenshot that I took with Emacs. See here's the source of it. So -Emacs made that. And here's the image. It's cool because you can even -do it again and again, and open more screenshots of screenshots. Yeah, -definitely Emacsception. Fun stuff. Anything else in chat? Heading -colors? Oh, yeah. I talked about the themes. This is another Kaolin -theme. I think the one in the talk was maybe this one, Aurora. Oh, -here, there's something funny when you start org-tree-slide with a -different theme. This top header bar gets the faces from that previous -theme. I have not figured out how to fix that yet. Did I have to -compile to get the screenshot? I think maybe I did. Yes, if I'm -remembering correctly. I got Emacs 27. I'm not on a Mac. I saw -alphapapa's comment on reddit, and then I recompiled it with Cairo -support. Yes. - -(<a href="#qnaVideo" class="time-link">12:18</a>) -Okay, lots of good conversation on here. Yep, I have like one or two -more minutes. Okay I guess while I'm here, I might as well say thank -you to the organizers. I really appreciate everybody's work on this. -It's fun to be a part of this community. I'm enjoying the other talks -I've seen so far today, and I'm looking forward to to the rest. It's -really interesting, just from being on Emacs in IRC for a few months, -I've already connected with a lot of interesting people and have a lot -of cool connections already. (Amin: Thank you for being a part of the -community, Grant.) That's good to be here. I have another talk -tomorrow as well. Oh, thanks for everyone in the Etherpad for putting -more comments on these questions here and taking the notes. (Amin: I -think that's about all the time that we have for the Q&A. Okay. Thank -you again so much, Grant, for your awesome talk and for popping in for -questions.) Yeah, thanks again for hosting. See you later.

I am Andrew Tropin. I +am a professional software engineer I +was playing with NixOS It's an operating +system based on the Nix package manager. +I came up with this interesting approach +for configuring Emacs. I want to share +it with you. + +00:00:24.056 --> 00:01:31.389 +I will start with the bold statement +that Emacs configuration is almost the +same as system configuration. It's not +related to that Emacs joke about Emacs +being an operating system. It's more +about Emacs being integrated with so +many tools inside the environment. For +example, if you don't even use any fancy +workflows, you use only plain Emacs +without any configuration, dired uses +ls, grep.el uses grep, and info files +placed somewhere in your system. Also +Emacs can interact with gpg, git, make, +and other stuff. When you grow your +Emacs Lisp init.el file or other files +in your .emacs.d directory, you get much +more integration with underlying +operating system. + +00:01:31.389 --> 00:02:08.622 +The question is: how to manage such +configuration? Because you can't just +take a bunch of .el files and move to a +different machine and be sure that +everything will work. Because you didn't +move your executables. You didn't move +configuration of other programs. You +didn't move your service configurations. +And you can't even just create dotfiles +for each program and move it with your +.el files. The approach would be a +little broader. + +00:02:08.622 --> 00:02:23.722 +Everything that I am showing today is +available on Github. Any source code, +you can find here. but my copy of the +repository is on my local machine. + +00:02:23.722 --> 00:03:45.889 +As you can see, the font is a little +small. And also, my terminal font is +also a little small. I can do a quick +fix and increase the font. But imagine +how cool it will be if you can have a +file which contains the configuration +for a system. You change some value. +Here, for example, fontSize = 16 and run +some command and based on this file and +some other includes your operating +system is built and all your environment +is set up and ready for use. For example +here, we already built the new operating +system, and everything is already +installed in my SSD. Now I can run the +program and you can see that my alacrity +terminal has much bigger font and also +if I restart my Emacs instance it by +default uses a much bigger font for any +buffer. Practical, and as you can see, +it's already working, thanks to Nix and +NixOS. + +00:03:45.889 --> 00:04:44.556 +I will explain a little later how it +works inside, but for now, let's specify +a little more what happened right now. I +fed my... Oh. It doesn't work. Sorry. I +want... I have my whole operating system +defined in a few Nix files. For example, +here you saw the file which defines some +variables for my environment and then a +few more files for different programs. +There is a folder which contains all +Emacs-related configuration. Also, there +are package definitions defined in Nix +package repositories which is also +included for the function which +generates the operating system. + +00:04:44.556 --> 00:05:11.689 +Getting all my configurations written in +Nix language and a few firewalls in ?? +languages, everything is gathered +together, and from that input and only +from that input, the new operating +system is built. Emacs now is a part of +this operating system. I can distribute +this Emacs configuration with all the +environment that I want. + +00:05:11.689 --> 00:05:50.789 +Practical so far. Let's clarify which +problems does it solve. First of all, +the integration problem. For example, a +few minutes ago, you saw that I changed +one variable. That was to update... The +first one, for my terminal, and the +second one, for my Emacs. It's pretty +good that a few different programs can +share some data. For example, you can +have one of them for every application, +or something like that and you change +only one value in one place and the +whole operating system is updated. + +00:05:50.789 --> 00:06:20.856 +Also, another problem is +reproducibility. For example, when you +install your new instance of Emacs on +your laptop or something like that, you +can be sure that you will get the same +package versions and you can be sure +that the configuration of your work +results in newly-updated or +newly-installed packages. + +00:06:20.856 --> 00:06:43.256 +Also, if you update packages, sometimes +it's hard to revert, because it's the +way your package manager almost every +time works. You're just getting the +latest available packages. If they are +broken, you need to wait for the +maintainer to update them. + +00:06:43.256 --> 00:07:39.656 +And also, your basic configuration +almost always doesn't contain any native +dependencies, like executables or +something else. Recently, I saw some +attempts to make it possible to use +use-package for those needs, like +ensuring native dependencies or +something like that. It's obviously... +If your configuration isn't reproducible +and it doesn't have your whole +environment, placed in one repository, +it's very hard to share such +configuration. You can share part of +your configuration and some instruction +how to get a similar environment, but it +doesn't always work. Let's go closer to +actually Emacs configuration itself. + +00:07:39.656 --> 00:08:10.839 +I had some experience with Spacemacs and +Doom Emacs distributions. I also watched +a lot of videos and articles by +Protesilaos and a lot of other custom +configurations of many different cool +people. And also I was inspired by +use-package and decided that I will +create a folding structure for my Emacs +configuration. + +00:08:10.839 --> 00:09:01.306 +I will be using subconfigs. It's almost +the same as layers in Spacemacs, or +modules in Doom Emacs, which are +self-contained. They contain Emacs Lisp +code which configures all packages +necessary for this part of +configuration. It contains all Emacs +dependencies like Emacs packages. It +contains all native dependencies like +binaries or maybe info pages or +something like that. It also contains +variables that can be shared between +Emacs and other applications, and it can +contain service or system definitions +which configure your systemd service or +something like that that you use in your +workflow. For example, for synchronizing +your e-mails. + +00:09:01.306 --> 00:10:06.922 +Let's start from just the example that I +already am... I have a folding structure +for my configuration. I have some files +here. early-init just has this. Nothing +changes. It will be copied to that +.emacs.d directory later with some +exceptions that it will replace the Nix +dir and a symlink will be created to it. +I have use-package-init.el. It's part of +configuration that will be on top of +everything to be able to use use-package +in my subconfigurations. And actually +some Nix code to glue everything up and +config dirs which contain all my +subconfigs. + +00:10:06.922 --> 00:11:10.105 +Let's start from faces subconfig. Let's +start from config.el which can be +familiar for many people. Just +use-package definition for faces package +and some configuration for it which are +setting some attributes. It reads some +variables. Those variables are actually +defined in a different place. If I open +default.nix file, you can see that it +contains the definition or subconfig, +and it should contain a definition of +variables that it uses by... I forgot to +move it from my original default.nix +file somewhere here. You probably can +find definition of those variables just +right here. + +00:11:10.105 --> 00:11:38.422 +I took values from my Nix expressions. +Those values will be shared across my +alacrity, Emacs, and other applications. +Later, they will be placed in generated +Emacs configuration. They will be +available for faces config. Here I will +be referencing them just like Emacs +variables. + +00:11:38.422 --> 00:12:39.222 +Let's take a look at another more +complicated example. For example, +org-roam package. Just a basic +use-package configuration which uses a +variable and the definition. It's a +little more complex than the previous +one. Elisp configuration in the same +file. emacsPackages specified here. +Those two packages: org-roam and +company-org-roam. systemPackages: it's +something that should be available on +your host operating system. And for +emacsPackages, you need sqlite package, +and also the definition of the variable +which will be passed in my Emacs +configuration later. It's equal to my +workDir, which is defined in my +environment, and a subdirectory of it. + +00:12:39.222 --> 00:12:43.222 +([Amin:] Andrew, you have about five +minutes including questions.) + +00:12:43.222 --> 00:13:26.222 +Oh, okay. I'm almost finished. It was +last example. Let me open my Org file. +Okay. Right here. I won't give you an +introduction to Nix itself and the +underlying mechanism, but I can say that +there's already a proof of concept +framework for utilizing Nix and NixOS +for configuring Emacs and making a very +complex workflow reproducible on other +machines. It gives everything that we +saw right now. + +00:13:26.222 --> 00:14:05.389 +For the future work, I plan to +reimplement it in Guile, which is a +Scheme dialect, which is another Lisp +language, for the GNU Guix operating +system, because I like Lisp languages a +little more than Nix languages and I +want to make this project from proof of +concept to some state which will be +user-friendly and available for other +people. If I will have a lot of time, I +will make an operating system which will +be inspired by Lisp machines to make the +whole experience very Lispy. + +00:14:05.389 --> 00:14:22.622 +Thank you for your attention and now I +will answer questions. Oh. There is a +lot of... Okay. I see some questions. + +00:14:22.622 --> 00:14:29.222 +Did you release some config files such +as Emacs custom.el, some of which have +sensitive data? + +00:14:29.222 --> 00:14:59.456 +Ideally, in the folding way, I create a +separate directory called +local/share/emacs, and I place custom el +files here. It's not synchronized in any +way, and it will be just lost in case +you move to a separate machine. I do it +for a purpose, because I don't use +custom.el. It's hard to make it +reproducible if you're using such +mechanism as custom.el. + +00:14:59.456 --> 00:15:06.656 +How do you learn the Nix language +basics? Just from the manual? + +00:15:06.656 --> 00:15:32.989 +I read a lot of documentation. Also, I +saw the course like Learn Nix in 15 +minutes. And also there was another +resource. Better to ask this question in +Nix or NixOS channel in IRC, which will +be treated in more details. + +00:15:32.989 --> 00:15:38.909 +What are the main advantages besides +switching computers, which most people +rarely do? + +00:15:38.909 --> 00:16:10.556 +For example, the original idea was to +make part of configurations available +for projects. For example, you have some +project, you made the setup, and want +other developers to use the same setup +on their machine, but you implement only +the part of stuff, like one subconfig +especially for this language for this +project. With such approach, you can +easily share such subconfig with other +people. + +00:16:10.556 --> 00:16:15.239 +Have you tried Guix in place of Nix? + +00:16:15.239 --> 00:16:41.239 +Yes, I tried it, and currently I am in +the state of switching from Nix to Guix. +You can follow my Youtube channel, I +think, I do streams twice in a month +talking about reproducibility and +related stuff. Probably soon I will be +talking about installation of Guix and +configuration of it. + +00:16:41.239 --> 00:16:50.406 +In case you're watching this video +later, you can find me somewhere on the +network using those contacts.

I have a +10-minute time slot at the EmacsConf and +I will show you a quick walk through my +GTD system in Org mode, so let's start +with capturing. We want to capture what +we do here. + +00:00:22.560 --> 00:01:03.600 +So the idea is I press F6 and I say: "I +want to make a small project because +this video will be a small project," so +the thing is: "Record a video for Emacs +Conf 2020." Video is recorded, edited, +and uploaded. We can also set the +timeline because we want to upload it. +The time, the deadline for uploads +is--we know it already--the 14th of +November. so let me put this in here. +See, this is done. + +00:01:03.600 --> 00:01:40.400 +Now, because it's a project... I mean, I +could say just one task to record a +video, but it's too much, so let's split +it down in a few small tasks. The next +one... + +00:01:40.400 --> 00:02:18.560 +So you see, I've just typed a few quick +tasks. We can see them if we look in the +capture file. You see, there's my +project entry and there are all my +tasks. Since it's a project, I can now +make it easy. I just indent every task +by one and then, so... + +00:02:18.560 --> 00:02:45.599 +Okay, so you see we have one project +here, and this one we refile now to our +backlog. So if we look in our backlog, +you see my project with all the tasks. + +00:02:45.599 --> 00:03:30.879 +So now, next one. I pretend now I'm +doing a weekly review. C-c x b. And I +already did some things, and now the +point where I am is scheduled tasks with +no date. Those are all those tasks. So I +have a weekly review helper that says, +okay, show me everything that I need to +schedule, plan. So schedule this class. +We do everything. + +00:03:30.879 --> 00:04:03.200 +So everything is scheduled now, and we +can check off that and so on. We can... +I have a plan for every day. That's my +free plan. I press F6, and I say p p +plan. Private things. You see there is +the first day, 12th of November, German. +And now I can look at what I have to do +today. + +00:04:04.239 --> 00:04:37.680 +My agenda view is very long, and I just +want to focus on a few tasks, so I +copied them to my daily plan. I just +want to show you. So I have a daily plan +for every day, and that means this one +is what I see, and this one is gone. + +00:04:37.680 --> 00:05:15.605 +So now, let's pretend we are working on +the first: we find the requirements for +the video. We had a look. Okay, I can +mark this task as done here because I +knew the requirements. C-c t. Done. +Format is 720p, webm codec. So this one +is done and I can mark it off here as +well. So now I have marked it off +everywhere. + +00:05:15.605 --> 00:05:24.639 +The good thing of my daily plan is that +I can really see it all the day. I stick +to this, what I decided in the morning +what I want to do. + +00:05:24.639 --> 00:05:58.319 +So let's go to the next one. Make a +quick test. Yeah, I did the test +already. I will do a small trick. I say, +okay, I record the video here. Video +recorded. Then let me do what to show. +Now I'm recording the video. + +00:05:58.319 --> 00:07:02.560 +Let's see. What we do: we had capture, +we had weekly review, we had daily +planning. How are we processing this? +Very nice. So let's pretend the video is +recorded C-c t done. Let me put this to +NEXT again. Start kdenlive to time +lapse. After recording it, I pretend +this is done now. C-c t done. Then I +have a video ready. Let's pretend I did +the upload as well. Done. Video +uploaded. So I can say everything now is +done. Save it, so tomorrow I see what I +did yesterday. Here I'm completely done. + +00:07:02.560 --> 00:07:40.455 +We have the weekly review.

Who am I? I'm Andrea. I work as a Scala software engineer somewhere in the Netherlands, and I inherited my passion for Emacs from my PhD supervisor. From that moment on, I got in synergy with it. You can find more about me and my interests at https://ag91.github.io. That is the place where I keep my blog and I blog on a weekly basis. Let's get into the bulk of the talk. Why I needed a vision. The main, main problem is that I have too many interests. I like a lot of things, and these things take time. Then I have too little time to do other things that are very important as well. And so I need priority. And the vision in my mind is both an ambition, something that I want to do with my life, and at the same time, it's a way to focus my efforts and get rid of some stuff that fundamentally is not something I really care so much about. Even if you come up with a vision and so with a smaller scope of things that you want to do, even then, you have to take this ambition of yours, this vision, and disassemble it in very small steps. Org Mode is very good at taking care of this because you can keep track of TODOs in Org Mode. So let me show you how I keep an agenda that also keeps track of my vision. For this talk, I have a running example. Vision will be "I want to bring joy to people." and "I want to live in synergy with the planet." Okay, so, given these two visions, let's open the agenda. You will see on the right that now I have some tasks, both on Tuesday and on Friday. Things to notice is that we said one of our visions is synergy with the planet, so some tasks are annotated on the left with this category and some with "Bring joy to people." In this way, you can distinguish where are my... In this day, where my effort is going in this day. The other thing is the specification of these tasks, and then at the end, you can notice a tag on the right that is essentially a guess of how long this task will have an effect over the future. So, for example, installing solar panel onto my roof is going to have an effect of 10 years over my life, if I manage to achieve that. That is my rough guess. You will notice that the ones that have a bigger amount, so 10 years over the 5 year one, because I order my day so that the tasks that are more important or that I believe are more effective over my future, I sort them so that they appear at the top. In this way, I can basically decide, okay, today, what should I... Find a video on Youtube, but I should take into consideration when I look at my agenda that I've traded that small fun for today with something that could have had an effect over a longer period of time. Let me show you how I also exploit the facilities that Org Mode comes with. I will... I have two templates available to me. I will choose one. The first thing that it asks to me is "How long will this affect your life?" So I like ... It will affect a long time, if I manage to produce only for myself. So I choose 10 years. And then I specify the task. So, "Learn how to keep bees." I collect this task. It will now appear in the middle because 10 years is between 20 years and 5 years. So I know that if I put some effort in learning how to keep bees, I should be quite happy for today. Okay. So, say that I do it, say that that's it... Once I've done this task, how can I be... How do I know how much progress I am doing? The way I can do that is by retrospecting weekly or monthly about the successes or the progress that I am doing. How I do it is simply by running this kind of snippet that shows me that for this month, I have done three tasks for bringing joy to people and three tasks for synergy with planet. This is useful because you can repeat it and it will be appended, so every time you run it again, you can compare if you are... how you are working towards your goal and if you're focusing more on bringing joy to people or if you're focusing more on synergy. Balance the effort. A thing that I want to share that I think will be useful to you is this function I use that I made for myself to create these statistics. It's a wrapper around the very enjoyable library org-ql, which allows you to query and group headings, do analysis on headings, or restructuring and view headings in a SQL fashion. The syntax is very similar to SQL. You can manipulate your headings and visualize them or just get statistics as I have done here. Finally, for this talk, say that you are doing progress, that progress most likely will generate some useful knowledge for yourself. My way to store this knowledge is through org-roam, another interesting mode that is very... that is becoming very relevant and known today. The idea is that I simply... If I learn how to make, how to install solar panels, that can be useful knowledge. I can link to some other knowledge that I have and so create my own knowledgebase, and save it for later use. My later use is typically, in this case, my blog. In here, I have a few notes that are basically a synthesis of knowledge that I have collected doing my tasks towards my vision. With this, this is all I wanted to show you for this talk. You can follow me on my blog at https://ag91.github.io . That is also where I am going to share a version of this Org Mode file that allows you basically to create the same kind of configuration I have here, and you can create an instance by running this snippet of Emacs in which you can just run this example. An extended example I will also add, to just play around safely with this kind of configuration. So enjoy the rest of the conference. Catch you later! Nice to meet you! +Welcome to my talk, Lead Your Future with Org. Who am I? I'm Andrea.

I +wrote this package because I was +overwhelmed with all the stuff I had to +manage working at home. I'd heard about +GTD. I saw someone using it with just a +small notebook. I wanted to do it in +Emacs because, well, Emacs can do +everything, right? + +00:00:29.199 --> 00:01:12.640 +I'm going to jump in quickly. Just so +you know, here's kind of a list of the +resources. Obviously, org-gtd, which you +can find there. You can open an issue, +ask me questions there about it. I use +org-edna, a package for state triggers. +I'm going to show this briefly when I +finish item in a project. +org-agenda-property, you will see in the +agenda. It's going to show to whom an +action has been delegated to. You will +see org-roam briefly as a reference +because that is what I have chosen for +my knowledge archival tool. You can +choose whatever you prefer. + +00:01:12.640 --> 00:01:57.520 +This is a quick, quick reminder on what +GTD is and how it works. This is not a +lesson on--a presentation on gtd because +that would be... Well, other people have +done it better than me. In short, +everything goes into the inbox. Then you +process the inbox, and you decide what +to do, if it could be actionable or not. +If it's actionable, it could be a +project or it could be a single action, +which you could delegate or schedule or +just do it. If it's not actionable, you +could just throw it away, incubate it +for later, or move it into your files, +reference. + +00:01:57.520 --> 00:02:27.200 +Over here, you can see the global +bindings for org-gtd. Those are the +actions, the functions I have made +available. This is in progress. There's +more to come. Some stuff is probably +missing. It's grown mostly from my own +personal use so far, so it doesn't have +things. In the bottom right, you can see +the agenda. + +00:02:27.200 --> 00:02:54.319 +One thing I wanted to do with this +package was leverage Org Mode as much as +possible. So I tried to not reinvent the +wheel as much as I could. That meant +reusing the agenda. You can see here a +couple of the things that are made +available or kind of customized or +configured for you, some of the opinions +that org-gtd has. + +00:02:54.319 --> 00:03:49.280 +Up here, for instance, you can see a +delegated action. So a delegated action +has someone to whom it's delegated. It's +my parents in this case. It has the name +of the action: ask parents what gift +they want. It's marked as the state of +WAIT because I'm waiting. It is +scheduled because you should ping people +or check on the status status of a task +when you're waiting for it, so you don't +forget about it or it gets lost forever. +I have a scheduled action to give a +talk. That's what I'm doing right now. I +have an incubated action which is also +scheduled: to make money through the +lottery. This is a thing to take a look +at for later, decide later what I want +to do. It might be actionable, it might +not be. I don't know right now, or I +didn't know when I processed it, so I +incubated it. + +00:03:49.280 --> 00:03:59.360 +Underneath, we have all the things that +are direct actions for me to take. + +00:03:59.360 --> 00:04:33.384 +All right. You see a little bit of the +preparation seeps through the actual +talk. I have here two... I have a single +action of "Steal Andrea's GTD +configuration" and an action to read the +GTD book. It's part of a project. So +most of the day-to-day operation with +with this package should come through +just having the agenda open and having +it be your source for the information +you need to know, so that you can do the +right thing. + +00:04:33.384 --> 00:05:18.960 +So let's take a look at what's +underneath all of this really quickly. +We have--There's three primary files. We +have the inbox. I'm gonna process it in +a second because there's two things +here. One thing to cancel, like an +action to not take. It's nothing. And +then something I will just put into +org-roam, just so you can see that there +is the incubate file. You can see here: +make money through the lottery, +captured, refiled here, and scheduled so +it would show up in the agenda right at +a given time. On the right, you have the +actionable file. This is the one that +has the most information, where most +things should go. + +00:05:18.960 --> 00:05:37.919 +So I have the single actions. They all +go underneath here. This is marked as +next because it's an action for me to +take. Delegated is marked as WAIT. It is +not an action for me to take. It's an +action for somebody else to take, but it +is scheduled because I may wanna... I +can check in at some point. + +00:05:38.400 --> 00:05:53.840 +Things that are scheduled, like "give a +talk," do not have a TODO or NEXT or +WAIT state because they are not bound +that way. They are time-bound, so they +will show up in the agenda when the time +comes. I shouldn't act on them or I +can't act on them beforehand. + +00:05:53.840 --> 00:06:07.520 +You can see here, I have two projects: a +test project (and I will do something +with this in a second) and then there's +this package "Make a GTD package." +There's a project here for me to create +this. It's made of a bunch of actions. + +00:06:07.520 --> 00:07:03.840 +I'm going to show you two things here. +One is: since I was trying to leverage +Org Mode as much as possible, I didn't +try to create very clever operations, +because Org Mode has a lot of very +powerful tools already. There's +automations I can add, but I thought it +might be better to leave more things in +the hands of the user. So here, in this +case, this test project we can just +archive. Right. That's just C-c C-x C-a +is the org-archive action. Save this. So +now if we go to... This will create an +archive file which will have this +information for later perusal if you're +interested. + +00:07:03.840 --> 00:07:27.680 +That's one thing. If we go back to the +agenda for a second, you can see these +things here. Org. So by the way, this +"parents" here was the org agenda +property. This is what shows here, +right? And here, if I finish "Read the +GTD book," I mark it as done. Now +refresh. + +00:07:27.680 --> 00:07:57.280 +You'll see that another item shows up, +and that is where org-edna comes in. +When an action is marked as done in a +project, the next to do action is +automatically marked as next, so your +agenda is automatically updated. This +was one of the nice things for me +because I didn't want to have to open my +file, go find the action, mark it as +done, find the next one, mark it as +next, and so forth. I didn't want to +bother with it. + +00:07:57.280 --> 00:08:20.720 +Oh, actually, you know what, let me show +you something else. This simple +project... I don't need this timestamp +to be here but I like having a capture +timestamp here, so I'm gonna make one +up. So this is the most convenient thing +that I think... This is one of the most +convenient things that I get out of this +binding. + +00:08:20.720 --> 00:09:00.080 +The next really convenient thing is the +way this gets processed. Let me show you +this. When you process the entire inbox, +what you see is the items one at a time, +so you can work with them. You can see +at the bottom... You can work with them +without being distracted. You can see at +the bottom the list of things you can +do, which are all the decisions you can +take from GTD, right? In this case, this +is one to throw out, so press t. You +have the option to make modifications to +this if you want to. If you have any +reason to store it, then you finish +editing. You can add a tag if you want +to, because this might still be +interesting, + +00:09:00.080 --> 00:09:37.457 +and then enter and it's done. Important +knowledge, I'm going to hit a for +archive it. I'm gonna start looking at +org-roam. So this is important +knowledge. I have to capture this. +That's it. I've captured it. It is done. +I go back to buffer, and I can mark it +with C-c. There's no archiving because +this is just knowledge. There's no +tagging. It's just knowledge. + +00:09:37.457 --> 00:10:15.440 +But then the simple project... I want to +show you this because there's some +automation that's pretty helpful. In the +simple project, I have my first action, +second action, third action. and you +see, this is all I'm writing. I'm not +adding any of the states, any of the +tags. They're going to be added by... +Here, I can add a tag if I want to this +project. I don't care right now, but you +know... I leave the tags to the user, so +they're not super relevant to me as a +package provider. + +00:10:15.440 --> 00:11:04.880 +This is where we are. This is the whole +thing. So now if we go back to the +agenda, I have a first action, right. +And if I go to the actionable file, and +now see, I have a simple project that +has my first action as NEXT, second +option TODO, third action as TODO. So +what I've... You know, as you can see... +I hope what I've tried to do is take all +of the tedium out of working with with +Emacs and Org Mode when working with +your actions so you could focus on what +you want to do, what you need to do, +what you care about, and the package +would take care of the rest. + +00:11:04.880 --> 00:12:32.000 +So the last thing I wanted to take a +quick look at was some of the the tests. +The code is available here. You can see +the code on... the code on Github if you +want. I've had some trouble writing good +tests for this because Org Mode was +written at a time before testing was +quite as important, I think, or valued +quite the same way, let's put it this +way. And as a result, a number of things +actually... It might also be a feature +of Emacs at the time, I don't know. But +a lot of things in Org Mode aren't very +testable, and so what I ended up doing +was just having an actual directory in +which I actually... with files, right? +So I don't have much mocking I can do. I +can't just do a bunch of fake files, +fake directories. So I actually go +through the process, actually create +files, and then actually have Emacs +pointing at this directory to process +and get the information. So I have to +define the key to test that it gets +bound properly. I have to set the +capture templates. The capture templates +are how things get added. I have a +wrapper control... org-gtd-capture +essentially is a wrapper around the +capture that makes sure the inbox is +there and then captures to the inbox. + +00:12:36.240 --> 00:13:45.360 +Making sure the items show in the agenda +when I'm done with the processing was a +little bit tricky. I had a bug and I had +to to fix it, so I just wrote this test, +but it's it's pretty convenient now to +have that, because it gives me a bunch +of sanity. So again, I have a capture, +and this is... I wanted to be able to do +this automatically but org-capture +itself is not super testable right now, +so the way it's... the way you test it +is just by programmatically calling it, +which is not exactly what I wanted, +because I wanted something more like the +user action, but I'll... You know, what +I can get. And then I can... I'll just +insert these words into the buffer and +then I'll finalize the capture. Then I +have another... I have a test package +here called with simulated input which +basically calls this and then enters +these user actions. Right, so like the +letter s, C-c c and then RET. And that +is, you know, choosing a single action, +then finishing the edit, and then adding +zero and not adding tags. + +00:13:46.480 --> 00:14:05.040 +As you can tell, there's a strong layer +of disconnect between the tests and what +they represent. That's a work in +progress. I have four tests. It's not a +lot, but I want to... I intend to add +more as I keep on adding more behavior. + +00:14:05.040 --> 00:14:34.880 +I would like this to be eventually a +sane starting point for GTD. There's a +lot of people like like Andrea, like +Rainer, like... I mean, if you search +for Org Mode and GTD, you'll find a lot +of blog entries, a lot of entries, a lot +of articles that explain how to connect +it together, how to think that way, how +to use all the tools that Org Mode makes +available. + +00:14:34.880 --> 00:15:20.560 +Hopefully, this package is a way to get +started without having to write too much +of your own code.

I hope you had, +well, quite a lot of talks ever since +the last one I did, and all more +interesting one after the other. You +know, I'm a bit in a bit of a weird spot +right now, because I'm supposed to be +presenting to you (as you can see on my +screen) "One big-ass Org file or +multiple tiny ones: finally, the end of +the debate," and it sounds about as +clickbaity as you can possibly get with +those topics. By the way, credit where +credit is due, the title is not mine. +It's actually from Bastien Guerry, the +current Org maintainer. + +00:00:58.434 --> 00:01:22.823 +Yeah, I wanted to talk to you a little +bit today about this question because if +you are used to going on +reddit.com/r/emacs , you know the +subreddit that we have, if you go on +Hacker News often, you know it's a +question that you see pop up every once +in a while. "Should I be using one big +file, or should I be using a lot of tiny +files?" + +00:01:22.823 --> 00:01:58.575 +I believe you know we've got defenders +on both sides. If I just show you one +example... We have Karl Voit. He's one +of the organizers for the conference. He +is the guy who probably has the biggest +Org Mode files right now in all the +people I know, and god knows I know +plenty of people use Org Mode. +But if you just look at this line--I hope +it's not too small; you just +make it a little larger--but +Karl basically has a file with +126,000 lines. + +00:01:58.575 --> 00:02:57.040 +I'm just going to pause and try to have +you imagine how large a file it actually +is. Just think about all of these lines +being tasks in your days. Think about +all those lines being about little +thoughts you know that you've had +throughout the day or project that you +were working on. It's massive. You know +one of the problems that Karl Voit +actually approaches on this topic is +that it takes him roughly 20 seconds to +get his Org agenda going, which is a +massive amount of time. I mean, we have +very fast computers now. You know, ever +since Emacs was created in 1976, +computers... I have no idea how much +faster they've gotten. And yet, you +know, for 100,000 lines, Emacs seems to +be choking. It's certainly not +reasonable, in a way, to have to wait 20 +seconds just for your entire file to be +parsed. So basically what I want to do-- + +00:02:57.040 --> 00:03:50.720 +By the way, I forgot to introduce the +presentation, but I'm Leo Vivier. I did +this before, for those who were around. +I help maintain a software which is +called org-roam, and that's the +expertise that I have on the topic. +Actually, if you go online, I do have a +Github page. I will make sure that you +have all the links available afterwards. +But I do publish my init files, and you +can see, if you scroll at the bottom, I +have a little demonstration which shows +you the fancy things that I can do with +my Org Mode setup. That might be even +interesting in light of the talk you've +just had about GTD stuff, because the +first one is about how I handle my +projects, the second one is about the +flow from a task as I work on it... So I +won't spend too much time on this, but +basically that's my expertise. I have +spent eight years working with Org Mode, +three of them actually thinking about +writing packages. + +00:03:50.720 --> 00:04:32.880 +The thing is, if I go into a little bit +of detail (and obviously it's only a +lighting talk, so I won't have time to +actually go really in depth about it), +but there is something in the Org Mode +library which is called org-element. You +have the name right there, +org-element.el, .el being for Elisp +file. As you can see, the page is on the +Worg wiki, so it's accessible by +everyone. It's basically the API that +Org Mode uses to parse Org Mode files. +For those who don't know, parsing means +basically checking a file, checking all +the contents of the file, and extracting +all the information that we need from +that file. + +00:04:32.880 --> 00:04:58.960 +As you can imagine, you all have Org +Mode files in your mind, well you know +they can be fairly complex. You can have +properties, you can have contextual +information, like if you write a line +which starts at column zero (which means +at the left), it doesn't have the same +meaning, whether or not it is before the +beginning of a headline or if it is +after the beginning of a headline. It's +going to be relatively different, +hierarchically speaking. + +00:04:58.960 --> 00:05:39.280 +So the problem, when it comes to the +question of many files versus one big +file or few big files, is that we always +have to keep in mind what org-element +wants you to do. The thing is, there are +plenty of problems when it comes to +parsing files, the first one being +obviously that Emacs is a single-thread +process (or has some threading +capabilities; we're not going to go into +the details right now, that's not my +goal). It makes it incredibly hard to +parallelize parsing processes with the +current technology. + +00:05:39.280 --> 00:07:03.759 +So you'd have to imagine that if you +have a very large file--if you go back +to the example of Karl Voit from before: +100,000 lines--that means that you have +to scan through every single line, +basically. Because sometimes... Let's +just say that you have a property +drawer, for instance, which tells you, +oh okay, this tree has the tag :foo:. So +the problem is, there are multiple ways +for you to define a tag. You can use the +usual way, which is about wrapping in +columns the :tag: at the end of a +heading. For instance, if I... (I'm not +going to switch to Emacs, that's going +to waste too much time) That's one way +to say your tag. But say, you have tag +inheritance, which means that when you +have a parent with a tag, you also want +the child to inherit the tag. If you +have first heading with the tag :foo:, +you have the first subheading, and the +tag :foo: is implied. Now imagine having +to do that with a file that is +completely nested, a file that has maybe +9, 10, 11 levels of depth to it. It's +mind-bogglingly complicated for the +software to do that, knowing that... +I've told you about tags, but any +property can be inheritable. Anything +like priorities, even. Though why would +you do this? You can have groups. You +can have all this. + +00:07:03.759 --> 00:07:21.957 +And as someone who went through the +trouble of optimizing his Org agenda... +So basically, if we go back to the +GIFs--oh god we've already had this +discussion between the "git" and "magit" +and now I've started "gif" and "gif" and +I only have one more minute left to do +so, so let's just +say I'm going to say "gif" +just to spite people... + +00:07:21.957 --> 00:07:41.360 +So if you go on the way I organize my +agenda, what I did in order to keep my +agenda build time under two seconds, is +that I've rewritten a whole lot of codes +to be able to parse my Org agenda files. +So the thing is, I'm going to be talking +more about this later. + +00:07:41.360 --> 00:07:44.479 +I only have, let's say, one minute to +conclude. + +00:07:44.479 --> 00:08:15.199 +So as you've gathered, I'm not going to +be giving you the answer right now. I'm +going to be talking about org-roam a +little later, which is about following +the principle of having many small +files. But as someone who has been using +one large file to manage my life, you +know, I'm sitting on the fence. I do not +know which one is the best, but I hope +that my presentation has given you a +little idea of what goes on behind the +principles. + +00:08:15.520 --> 00:08:52.000 +You also need to think about the +philosophy behind the organization of +your notes. I hope to be approaching +this topic with you in about two hours +or so (maybe one hour actually). I'm +actually finished. I've decided to leave +you two minutes of questions. If someone +could feed me the questions, that might +be best, because I don't want... oh +actually I can just open the pad. I can +just open it. Give me a second, okay. +Just loading up. I might stop showing my +screen. That might make it easier. So I +mean if you can make myself big now on +the screen, that would be splendid. +([Amin]: yeah sure) + +00:08:52.000 --> 00:09:13.920 +Thank you. Where are we... Question 12. +Okay, so what's better, one big file +or...? Is it a jab to tell me that I +haven't answered the question because +someone just +asked me the question? Well, personally, if +I were to give you a quick answer in +20 seconds, personally, I think it's a +question that is contextually based. + +00:09:13.920 --> 00:09:45.890 +Do you want something that is efficient +as far as optimization is concerned? +Then you need to think about this. +Personally, for all the organization +that I do, all this stuff, all the TODOs +that I handle, I like to do this in one +simple big file because you benefit from +all the refiling capabilities of Org +Mode, so I would do that. But for +knowledge management, for note-taking +and all this, well I'd much rather +follow the org-roam way of doing things, +which is about having many small files. + +00:09:45.890 --> 00:09:57.040 +I'm not getting any more questions. I'm +not sure if there is one on IRC that +could be fed to me. Otherwise, I'm happy +to pass over to the next speaker. + +00:09:57.040 --> 00:10:06.520 +By the way, just before I finish, your +world is a lie. It's not a three-piece +suit. I'm wearing jeans below, so I hope +that satisfies your curiosity. + +00:10:10.640 --> 00:10:35.680 +Okay, there's one more question +appearing. "but otherwise one big file +to have everything..." So I'm putting +you on the spot, I believe. It was such +a short talk. You know the problem is, I +just wanted to give you a little answer. +A little, you know, path of thinking on +this topic. Obviously it's a topic I +could be spending 40 minutes on, but I'm +going to be drained, you're going to be +drained, nobody's going to be happy if I +do this. + +00:10:39.440 --> 00:11:08.240 +Someone asked me if I switch between +British and French accents. A little +secret for you: when I'm stressed, I +tend to revert to a French accent, so +you can measure the amount of stress +that I'm feeling during this talk with +the amount of h's that I drop and the +amount of sheer fright that you can see +sometimes in my eyes, when I'm thinking +about what to say next. + +00:11:08.240 --> 00:11:17.040 +All right sir. So, Amin, do you believe +we can leave it at that? I'll be... +People will see plenty more of me later +on, anyway. + +00:11:17.040 --> 00:11:27.120 +([Amin:] So, looking at the schedule, I +think your talk has until like 2:02, +meaning like five or six minutes from +now.) + +00:11:27.120 --> 00:11:28.000 +Oh, right. + +00:11:28.000 --> 00:11:33.920 +([Amin:] So if you do like to take one +or two questions, to add two more +questions, by all means.) + +00:11:33.920 --> 00:12:20.555 +So someone has asked me what is the +Emacs icon (sorry, see, another French +accent) here in my status bar... Oh +sorry, I'm not sharing any more. I might +just share again just so that everyone +can catch a glimpse of that. There we +go. Allow... So it should be... So if +you could make me small again, Amin, I'm +not sure if it's going to do it by +itself, but I do have a little icon here +in my status bar which is basically a +way to interact with org-protocol. I'm +not going to look for it right now, but +it's a browser extension that is +developed by one of my friends over at +Ranger whose name is Li Fong (??) and +it's very useful. I'm someone who uses a +lot of Org protocols. + +00:12:20.555 --> 00:12:53.600 +And by the way, I used to teach English +to high schoolers, and they were +supremely worried when I showed them my +status line and they saw "kill" and +"explore" in my status line. As fellow +Emacs users, you know that obviously +kill means to kill a selection of text +and keep it inside your clipboard, but +for my students, they were very worried +about what their professor was up to +during his nights. + +00:12:53.600 --> 00:13:01.920 +So let's see if we've got more +questions. I'm showing you the questions +on the rainbow. Let's see if we've got +more. People are posting a lot of +questions now. + +00:13:01.920 --> 00:13:06.399 +So how do you feel about archiving files +in Org Mode and how can that work? + +00:13:06.399 --> 00:13:59.519 +So one of the things when we think about +optimization is: yes, archiving done +trees is a good idea because it means +that if we go back to the org-element, +the way it works (and we'll get into +technical details afterwards; I'm giving +a presentation about org-roam technical +aspects, sorry, so I'll have a chance to +expand a little more on this) but +basically, org-element needs to... Every +time it sees a TODO, it has to consider +it, even though it is a done TODO. Why? +Because let's say, for instance, that in +your agenda you want to activate log +mode, which is going to show the tasks +which are done... Now you could be +clever and say, oh okay, the Org agenda +does not need to show done items, so +it's not going to look for them, but the +problem is that org-element is always +called. It always needs to parse the +buffer. + +00:13:59.519 --> 00:14:22.079 +You know, Nicolas Goaziou, who is the +French developer who's worked a whole +lot on org-element has gone through a +lot of trouble to optimize org-element, +but the problem is there's just so much +that we can do with a concurrent +process. Right now it leaves somewhat +things to be desired, but we're working +on it. + +00:14:22.079 --> 00:14:32.639 +One more time... I feel like I spent +half of this talk teasing my next talks, +but I'll be talking more about this in +my future talks in about one to two +hours. + +00:14:32.639 --> 00:14:36.079 +So, continuing with questions, how big +are my Org files? + +00:14:36.079 --> 00:15:04.880 +So in the background, I'm just going to +check how many lines I have in my main +file. +In my own file, so the one I told you +about where I keep all +my TODO GTD stuff, I have +38,000 lines, which is... +It's sizable, definitely. +But I do archive a lot of stuff, +so that might be a slight difference +between myself and Karl Voit, +even though I don't remember if they +actually archive stuff. + +00:15:04.880 --> 00:15:12.560 +So does it not consume more resources +and time to load multiple files files +than a large file or the same content +now? + +00:15:12.560 --> 00:16:00.560 +Theoretically, yes, having many files +open concurrently is slightly slower +than having one main file opened. Now +the problem is for those of you who have +large files, you may have noticed that +when you are scrolling in a very large +file, it starts taking quite a bit of +time. Why? It's because in Org Mode, you +have a lot of content that is hidden, so +when you have the view mode which hides +as much stuff as possible, meaning that +you only see the top heading--and I'm +checking the time, Amin, don't worry, +I'm finished on this one-- when you're +hiding a whole lot of stuff, Org Mode +needs to keep track, or I should say, +Emacs needs to keep track of which areas +of text to show and which areas of text +to hide. + +00:16:00.560 --> 00:16:21.199 +The problem is that when you're hiding +stuff-- let's say you're moving from the +first heading to the second heading, but +you've got like 10,000 lines between +those two headings-- well, Emacs needs +to compute the difference between the +two passages, and that takes quite a lot +of time. That's why you might realize +that it's a little choppy when you start +scrolling in large files. + +00:16:21.199 --> 00:16:30.719 +Anyway I could be answering questions +about Org Mode for literally two hours +straight, +so I'm gonna hand it over to the next +speakers. I'll be seeing +you guys a little later. + +00:16:30.719 --> 00:16:33.440 +([Amin]: Thank you very much, Leo.) + +00:16:33.440 --> 00:16:34.889 +Oh, thank you. + +00:16:34.889 --> 00:16:36.959 +([Amin:] Yes.

This is work I +did with Ray Puzio and Cameron Smith. +They're the main protagonists in this +story. They are researchers who've been +working on theoretical biology. In a +typical project, they may use Maxima and +Julia. Their work combines biology, +physics and computer science. The latest +work-in-progress is on branching +processes for cancer modeling. + +00:00:30.800 --> 00:00:48.640 +How can Emacs possibly help? Let's have +a look. Moving code and data between +these different programs by hand is +annoying. Separate workflows for writing +up notes and preparing publications is +perhaps even more annoying. All of it is +time consuming and error-prone. + +00:00:48.640 --> 00:01:10.057 +So what about maybe using Jupyter? We +found something called Script of +Scripts. It solves some of those +problems because you can use Maxima and +Julia together, but we were quite happy +to explore Emacs-based solutions, being +Emacs enthusiasts. We even got Cameron to +be enthusiastic about doing Emacs, so +that went nice. + +00:01:10.057 --> 00:02:05.657 +Here's a little feature grid of Emacs + +Org versus your generic tools that are +in a different, more general ecosystem. +As you can see, it's quite +feature-complete. You've got your +maxima-mode, julia-mode. You can use +both of them inside of org-mode. You can +present things with org-tree-slide. You +can set up a wiki inside of org-roam. +This is one I found rather recently. You +can even use compatibly with org-roam, +something called logseq, which is in the +browser, so that's nice. You can do +real-time collaborative editing, either +in a kind of pairing style or in a more +Etherpad style. Obviously, you can +manage your references. You can typeset +whatever you want. You can publish work +in progress on a blog. Firn is another +one of these external Org Mode tools. +It's not actually in Emacs, but works +with Org Mode stuff. And, you know... So +we're good to go with all of that. + +00:02:05.657 --> 00:02:13.890 +So what does that look like? Well, +here's a little example from before they +were doing... before we started really +thinking seriously about this stuff. + +00:02:13.890 --> 00:02:45.280 +So this is just Maxima. Well, Maxima +doesn't have a long running process by +default. If you've ever used Python, you +have something called sessions. They +don't have that for Maxima, at least not +by default. So how... What was the +workaround? There's this thing called +solve-for-u here that shows up down +below again in these angle brackets, +which you've seen maybe in someone +else's talk, which means go to the +previous thing that was named +solve-for-u and do that all over again, +so they do that over again. + +00:02:45.280 --> 00:03:00.640 +Here's the little Maxima code for +defining usol, so you've now defined +usol, and then you can use it in the +next expression. You get out a nice +juicy zero at the end. It's a little bit +like a partridge in a pear tree to have +to redefine everything every time. + +00:03:00.640 --> 00:03:22.590 +So this is clearly at the level of +work-around. Maybe just one more time +looking through that stuff. Sorry. So, +looking through that stuff, this is... +We're going to need something like that, +probably, for stitching Maxima and Julia +together. so it's good to look a little +bit about how that might work. + +00:03:22.590 --> 00:03:46.923 +First of all, you can cache results, so +if you wanted to save the date out of +block one at a certain time and then use +it again later... At the time when I ran +this code, you can see I've got two +slightly different time stamps down +below. One's the cached result, and the +other was the result of reevaluating the +block. So you can move things around. +That's going to be useful. But you know, +that's not really the main problem. + +00:03:46.923 --> 00:04:11.760 +The main problem is making Maxima +long-running. The core of this talk is a +new observant facility, which is a +general purpose way to do that kind of +thing, which involves a very simple +change to ob-core. We'll give a quick +overview of that and show an example. So +here's the example, a very simple sort +of silly example. + +00:04:11.760 --> 00:04:30.240 +What does it mean to have a long-running +process? Here, I've set this display2d +to be false, which just means that +things are going to come come across in +1d. Then I ask it to expand something. I +get LaTeX by default. So that's what it +means. It's that I've sent something in +and it's going to come across in one +view, which is great. + +00:04:30.240 --> 00:04:40.320 +Maybe you'll also notice that there's no +semicolon, if you're a Maxima fan, and +things are coming across as TeX. So +those were some little bonus features. +I'll show you how that works later. + +00:04:41.040 --> 00:05:13.759 +The change to ob-core is as follows. +Actually, this should say... Instead of +stream here, it should say servant. +Sorry. We tried an experimental version +which was called stream, so now it's +called servant. But all it does is it +overrides org-babel-execute lang for +arbitrary lang if you have a servant in +your params. So that's the change that +hasn't been pushed out or sent as a +patch to anybody, but it's a pretty +minor change. + +00:05:13.759 --> 00:05:30.720 +Here's an overview without the code. +Just a high level overview of +observant.el. It stores information +about these processes in a hash table. +It can do pre-processing and +post-processing. It does all these +things. It stores the output. + +00:05:30.720 --> 00:05:40.639 +I mentioned here that, in principle, we +could store lots of output and have a +kind of browsable history, although we +don't do that presently. But that's what +observant does. It does what you might +expect. + +00:05:41.440 --> 00:06:16.960 +Here's the Maxima on-ramp to get Maxima +brought in. You have to obviously have a +Maxima process you can call. puthash... +this is the preprocessing thing I +mentioned, adding in some Tex and adding +in-- or deleting, rather--a substring. +Here is why you delete the substring. +It's because Maxima thinks it's a good +idea to tell you false once you run +check on things. You've got to delete +that back out to get something coherent +out of it. So this is how to set up +Maxima. + +00:06:16.960 --> 00:06:25.440 +That's enough, really, of the demo. It's +not really a demo for show and tell, but +as this is an experience report, I +wanted to talk about the experience of +doing this. + +00:06:25.440 --> 00:06:42.880 +Some negatives, like we tried to get +Emacs Jupyter working prior to working +on observant. We couldn't get it doing +everything we wanted, despite a bit of +heavy lifting and debugging and stuff. +So that's not finished. That was a bit +difficult. + +00:06:42.880 --> 00:07:11.695 +On the other hand, working on observant +was fun, pretty lightweight, and easy. +We got some experience co-editing things +with these real-time tools. Obviously, +the stack is somewhat work in progress. +I just wanted to give a shout out to +crdt which was really fun, and Qiantan +was making bug fixes for that as we go. +Similarly, for firn and logseq, the +maintainers were really responsive, so +that was nice. + +00:07:11.695 --> 00:07:27.120 +We did try to get Emacs running in the +browser, thinking it would be really +nice for people who didn't want to +install it to get a chance to just try +it, but actually, browsers capture +things like C-n, so that was a bit +annoying. + +00:07:27.120 --> 00:07:33.759 +But we did get lots of great feedback +and interaction with people, including +around this conference. Thank you to +those who we've had discussions with. + +00:07:35.599 --> 00:08:19.120 +So, future work. Okay, so... Maybe you +remember, I gave a talk a few years back +on Arxana. What might this have to do +with Org Mode? That's always the +question one asks about Arxana. +Arxana... One of the things it does is +transclusions, and so that could be +actually very helpful in connection with +this "combined notes and write-up" +workflow. So you might have an Org Mode. +Some of these results we got back as raw +results could go right into your +write-up in a convenient way, at a level +above-- transparently, a level above the +notebook. So you'd have the notebook +alongside the write-up in that case, +which is a variation on the literate +programming workflow. This is +speculative. Who knows? + +00:08:19.120 --> 00:08:33.357 +The other thought is, +it just relates to the idea of network +programming. So we can imagine these +networks of computational nodes +sitting inside of org-roam, +calling each other. +You would want to maintain some +kind of model of that process. + +00:08:33.357 --> 00:09:11.680 +A general question is: how do we have a +remote control for long-running +processes? You could do that in Lisp or +Clojure, but maybe we could have +something a little bit like that here. +Conclusions: what have we actually +addressed? Well, we addressed accessing +any long-running process with a simple +Org Mode interface. Obviously, we're not +the only people to think about +notebooks, but we think that Emacs has +some advantages related to reproducible +research and interdisciplinary +collaboration. Let's just say that we +think something is reproducible if it's +actually teachable to someone new and +they can do it. Org Mode seems very +useful for that. Many of the other talks +have touched on this. + +00:09:11.680 --> 00:09:27.857 +Interdisciplinary collaboration is +great. This was an interdisciplinary +collaboration on some level, but what +about future work for bringing in +scenario planners, simulation +scientists, and local farmers, and +building something that they can all use +that's more than the sum of the parts? + +00:09:27.857 --> 00:09:38.135 +So a little future work for everybody +else here. We think science should be +widely teachable, shareable, +semi-automated, transdisciplinary, and +real-time like EmacsConf. + +00:09:38.135 --> 00:10:00.240 +So you can get in touch via these +methods. The code--which is very much +early stage work in progress, as this +was meant to be an experience report, +not a "it's all done, here, it is +polished" report-- it's also online if +you'd like to have a look. That's the +end of the talk. I don't know if there's +time for questions or not, but um I'm at +your disposal now. Thank you. + +00:10:00.240 --> 00:10:14.240 +(Amin: Many thanks for the tough job. +Let's see. We have about I think four +minutes for questions, and we have a +couple of questions on the pad. Would +you like to read them yourself or should +I read them to you?) + +00:10:14.240 --> 00:10:18.079 +Just for the sake of easy management why +don't you read them out, if that's okay? + +00:10:18.079 --> 00:10:33.760 +(Amin: yeah, sure. They ask, "Have you +looked into trying Sage Math? I've long +wanted to use Sage Math in Org files.") + +00:10:33.760 --> 00:10:44.839 +Ray: Right. I wrote the answer that it +should be possible because one can call +it from a command. + +00:10:44.839 --> 00:11:00.640 +(Amin: okay, and I see there's another +Sage Math question that you seem to have +answered as well, so I guess I won't +repeat that. There's... "Let's not +forget about embedded Calc in Emacs.") + +00:11:00.640 --> 00:11:08.240 +Joe: So the first demos actually were +with Calc. That's useful. Although I +think it was a different--kind of a +different command line. + +00:11:08.240 --> 00:11:11.839 +Ray: Well, that was UNIX Calc. + +00:11:11.839 --> 00:11:13.839 +Joe: So, sure, there is calc, so that... + +00:11:15.680 --> 00:11:19.120 +Ray: Calc is already in Org Mode. + +00:11:25.680 --> 00:11:57.290 +(Amin: Still looking for questions. +Okay, I think that's about it. I don't +see any questions on the Etherpad. And +let's see... Anything on irc? Nothing +but praises and everyone thanking you. +Thank you.) + +00:11:57.290 --> 00:11:59.120 +Ray: all right, you're welcome. + +00:11:59.120 --> 00:12:01.923 +Joe: Thanks a lot! +We'll see you guys around then. + +00:12:01.923 --> 00:12:06.800 +Amin: Cheers, and see you around! diff --git a/2020/info/14.md b/2020/info/14.md index 9d7ee315..dfb65c43 100644 --- a/2020/info/14.md +++ b/2020/info/14.md @@ -2,7 +2,9 @@ Adam Ard [[!template id=vid src="https://mirror.csclub.uwaterloo.ca/emacsconf/2020/emacsconf-2020--14-readme-driven-design--adam-ard.webm" subtitles="/2020/subtitles/emacsconf-2020--14-readme-driven-design--adam-ard.vtt"]] -[Download compressed .webm video (21.4M)](https://mirror.csclub.uwaterloo.ca/emacsconf/2020/smaller/emacsconf-2020--14-readme-driven-design--adam-ard--vp9-q56-video-original-audio.webm) +[Download compressed .webm video (26.6M)](https://media.emacsconf.org/2020/emacsconf-2020--14-readme-driven-design--adam-ard--compressed32.webm) +[Download compressed .webm video (21.4M, highly compressed)](https://mirror.csclub.uwaterloo.ca/emacsconf/2020/smaller/emacsconf-2020--14-readme-driven-design--adam-ard--vp9-q56-video-original-audio.webm) +[View transcript](#transcript) Many source code projects these days begin with a README file.

Welcome to Readme Driven +Design in Emacs by Adam Aard. If you're +a programmer, you're accustomed to +putting a README file at the root of +your project. It's usually a Markdown +file But if you use an Org Mode file +instead, you can take advantage of the +great features that Org Mode provides, +including literate programming, which +lets you generate your source code and +Markdown documentation dynamically. +I want to walk you through a little bit +of what this looks like. + +00:00:37.120 --> 00:01:03.520 +When you start a project, especially if +if you use something like Github you +begin with an automatically generated +README.md file. So just delete that +and instead create a README.org file. +Starting with an empty Org file, +like you see here, you can begin +by recording important information about +your project goals. You can add diagrams, +code snippets, to-do lists, time tracking +and much more. + +00:01:03.520 --> 00:01:38.880 +I'm going to drop in some documentation +that I've written about about my project +here, so you can see what this would +look like. As you can see, I have a +title, and a description, and then a +subsection as well as some code +snippets. You can see that Org Mode does +a great job of formatting lists, code +sections, diagrams, and so forth. It's +as good or better than Markdown, but +when you use it in Emacs you can do a +lot more. + +00:01:38.880 --> 00:02:08.000 +For example, you can dynamically create +diagrams using Graphviz from a text +description. If you go to this source +block here and hit C-c C-c, you'll see +that we generate a diagram dynamically +You can run these code snippets in place +and get the results to show up inside of +your file, which is a really powerful +paradigm. + +00:02:08.000 --> 00:02:19.520 +But most importantly, for my purposes +here, Org Mode provides you the ability +to do literate programming. + +00:02:19.520 --> 00:02:34.720 +So take a quick look at this diagram +that I generated here. It gives you a +quick overview of what I mean by +literate programming and how I'm using +it. You can see that we start with a +README.org file on top. + +00:02:34.720 --> 00:03:17.120 +At this point, we can do one of two +things: tangle or weave. Tangle is used +to describe the process of generating +source code, while weave is the process +of generating documentation. These are +terms that Donald Knuth used. He's the +one that came up with the idea of +literate programming in the early 1980s. +But this is really all that there is to +it. You just... You are simply using a +literate source file, in this case the +README.org, to generate the rest of the +project files, basically. + +00:03:17.120 --> 00:03:59.479 +So let's dig in to the details of how +this works. I hope you... Hopefully +you'll see how cool this is. So +returning to the file here. Let's assume +we have enough documentation now, that +we want to get started coding. So maybe +we'll just start with like a Hello World +app, just so we can make sure that our +environment is set up correctly. Let's +get started with a code block. So I +created a little snippet to help me add +a source block for literate programming +quickly. There's not much to it, but +there are some important annotations +here. + +00:04:01.599 --> 00:04:55.360 +Excuse me. There's a property called +:tangle and that takes a value of a file +name. Then there's also a :noweb +property called no-export. Basically, +the noexport--we'll explain that a +little bit more later It has to do with +how the tangling is done in the tangle +step versus the weave step. I'll explain +that a little bit more. But the tangle +field just simply tells Emacs where it +needs to generate the main.go file and +where it needs to put it on the file +system. + +00:04:55.360 --> 00:05:21.520 +You'll notice that we're going to use +Go. That's just the language that I've +been using the most lately, but this +programming strategy is +language-agnostic. You could use any +language or any mix of languages. You +could create some files in Python, some +files in Go, some files in Lisp, or +whatever you want. + +00:05:24.720 --> 00:05:56.400 +Let's create just a little Hello World. +Let's use another snippet here to +generate the basics of a Go program. I'm +just going to print Hello World. So +that's... And then let's make it a +section in our file. So now you can see, +we've got this snippet. + +00:05:56.400 --> 00:06:42.319 +When you have a source block in inside +of Org Mode, you can easily pop into a +language-specific buffer by typing C-c ' +(single quote). So you can see, now I +have a buffer that's in go-mode and +gives you all the ability to edit like +you would normally. If you hit C-c ' +(single quote) again, it goes back and +any changes you make will be updated +there. But you can do quite a bit just +inside of here too. There's quite a bit +of language-specific functionality just +in place, so you don't always have to go +over to a separate buffer. It's a nice +option sometimes. + +00:06:42.319 --> 00:07:12.240 +Now that you have the code in here, +you're going to want to run it. Right +now, it just lives here in this +documentation. You need to get a copy of +it into a separate file, and that's the +tangle process that you you need to +follow there. So I'm gonna drop in a +little bit more doc, a little bit more +documentation really quick here. + +00:07:12.240 --> 00:07:44.879 +Okay, all right. So just as a side note, +I like to follow this process. Whenever +I have an operation to perform, I'd like +to document it here with a snippet that +can be executed inline. Then I don't +have to leave Org Mode, and I don't have +to try to remember what I did later. So +instead of just trying to do an +operation, the first time I do +something, I take the time to figure out +what it is and document it, so then it's +recorded. + +00:07:44.879 --> 00:08:14.400 +So here we find that to do a tangle +operation, you run the command +org-babel-tangle, which is an Elisp +command. If you hit C-c C-c to run it in +place, you get the result of main.go, +which basically is telling us that we've +tangled one file called main.go. You can +see that that's true if you go to the +file system and you look. + +00:08:14.400 --> 00:08:41.120 +Now in our demo directory, we have a +README.org, we have that PNG that we +generated, but we also have a main.go. +If you visit that file, you'll see that +it's just the source code that was in +our documentation, which is exactly what +we expected and what we wanted. So +that's good. +So if we return to where we were at... + +00:08:41.120 --> 00:09:43.012 +Now we're at the point where we have a +file on the file system. Now we need to +build it and to run it. So let's follow +the same philosophy, where let's +document these operations that we're +going to perform. I'm dropping in a a +build instruction section and a run +instruction section. As you can see +here, we have a little a bash source +block, and another bash source block. +This one compiles. The go build command +is what compiles a file. Then the file +that gets generated should be called +demo. So we just run it here. If I type +C-c C-c, we get an empty results block. +When you compile things, no news is good +news. It means there's no errors. + +00:09:43.012 --> 00:10:30.839 +So presumably, we've created an +executable that's called demo. Let's +look again at the file system and +regenerate... Yep. What we have here is +a demo executable, which is exactly what +we wanted. Let's go back. Now we should +be able to run it. C-c C-c, and we get +Hello World as a result, which was +exactly what we were expecting. So +that's already pretty cool. You can do +that much. + +00:10:33.040 --> 00:11:09.760 +That's really just the tip of the +iceberg. To really use the more +impressive features of literate +programming, we need to do a little bit +more at least. Really, to get the full +benefit of it, we need to add some +sections that will cause Emacs to have +to tangle or assemble this file from +different pieces. + +00:11:09.760 --> 00:11:36.240 +Imagine that we wanted to take this file +and maybe kind of templatize it. So, +using literature programming syntax, +this angle bracket syntax, let's say +that we want to create an imports +section, a functions section, and then +maybe just a main section. We'll get rid +of this. + +00:11:36.240 --> 00:11:56.639 +So now you see, we've created something +that looks a little bit like a template +or a scaffolding or outline for what our +file is going to be. It looks a little +bit like pseudocode. What we're going to +have literate programming do is +dynamically insert those things into +those slots. + +00:11:56.639 --> 00:12:36.639 +So the first thing we need to do is... +So let's create a section called "Say +Hello." We want to add some +functionality that makes our program say +hello. So using a different snippet that +I have for creating something that I +call like a literate section, basically, +we create a another source block that's +almost the same as the one for the file. +It just has a few differences. Say we +want to drop code into the import +section and we want it to be in Go. + +00:12:36.639 --> 00:13:14.399 +Here we use the same :noweb no-export +syntax, but then we've added this +:noweb-ref imports, and this ties that +slot to this reference. It tells Emacs +that when you tangle, we want to stick +whatever's in here in that spot. You +skip the tangle file name section +because you're not actually creating a +file name. You're putting information +into an existing file. So here, we would +just add the "fmt" for the imports. + +00:13:14.399 --> 00:14:10.320 +Let's add another section for functions. +Let's just create a function called +sayHello that doesn't have any +arguments. No return types. All it does +is pretty much the same thing as we did +before: just print something. Let's just +say "Hello EmacsConf" this time. Now we +have a function, and now the function +won't do anything unless we invoke it. +Let's do one last literate section +called main. Make that Go source block. +Then let's invoke that function. + +00:14:10.320 --> 00:14:39.839 +Now you can see that we've got our +scaffolding outline, and then we have +the sections that we want to get tangled +or inserted. I've used this syntax. It's +kinda borrowed from literate programming +a little bit with a +=, so really it's +just saying that I want to append this +item into the import section It's really +just to make a little bit more clear +what's going on. + +00:14:39.839 --> 00:14:57.760 +When you generate documentation, you +won't see these particular property +annotations, and so you won't know +immediately that this section goes in +the imports area. So I usually put a +little bit of documentation on top +there, so that it's easy to see. + +00:14:57.760 --> 00:15:21.120 +You would, probably, if this was very +complicated, you'd put some +documentation above to explain what you +were doing, maybe right here. You could +picture yourself maybe explaining a +complicated algorithm or something up +here and having a nice way to document +it. + +00:15:21.120 --> 00:15:28.045 +So now that we've got that here in the +documentation, we need to figure out... +We need to make sure that it's going to +tangle properly. + +00:15:28.045 --> 00:16:20.479 +Your best friend at this point is a +keyboard shortcut that lets you preview +the tangled operation. If you say C-c +C-v C-v, it will create a new buffer +with the tangled contents and so you can +see here that the fmt import went to the +right place, that function went to the +right place, the function invocation +went to the right place. We're feeling +good. You can nest these things many +layers deep. If you came into the +sayHello function, you could add more +sections. It'll go through and it'll +keep track of all that and tangle it for +you so you really get a lot of freedom +and flexibility for how you want to +document things by doing this. + +00:16:20.479 --> 00:16:57.645 +So now that we've previewed it and we +feel good about it, we need to tangle so +we get the file on the file system. so +C-c C-c and get... just main.go comes +back again. C-c C-c and no errors come +back. Then if we did this right, when we +run this, we should get "Hello, +EmacsConf." So C-c C-c, Hello EmacsConf. +I think that's pretty, pretty cool, +actually. + +00:16:57.645 --> 00:17:23.280 +So we've got the breadcrumbs of the +process we've gone through to get to +this point, this initial document that +has some tangling in it. We have +documentation for how to tangle, how to +build, how to run. We've really built a +nice foundation for moving forward on +our project and a nice way of breaking +things out and documenting further. + +00:17:23.280 --> 00:17:38.640 +The last piece that we need to +take care of is the weave that +I showed you in the diagram above. +So one more time, we'll drop in + +00:17:38.640 --> 00:18:35.520 +some documentation, this time on how to +weave. It's really just an export +function. it's not... There's not a +separate weave command going on here. +we're just going to export what we've +got here into a Markdown format. We're +using org-gfm-export-to-markdown, which +is the Github style markdown. You can +use the other, more standard type as +well. Hit C-c C-c. Now you see we've got +a README file, and if you look in the +file system, we've got that right there. +If you go to something like ghostwriter +and open that file, now you can see that +it's generated some documentation. + +00:18:35.520 --> 00:18:48.559 +It puts a index at top at the top. I +usually turn that off. It's easy to do +that by putting a property at the top of +your Org file, but some people like to +have an index. + +00:18:48.559 --> 00:19:22.802 +Here you can see that it has generated +pretty nicely and formatted snippets +well, put the diagram in there, and then +it's preserved this literate programming +syntax, which is important because +that's how we want to view the +documentation. That's what the +no-exports property was trying to +maintain. no-exports means when you +export, do not try to tangle. + +00:19:22.802 --> 00:19:43.600 +Hopefully that makes more sense now. Now +you can see all the documentation. I +think it demonstrates a pretty useful +feature that's inside of Emacs. +Hopefully you'll have as much fun using +that as I have.

Hello, everyone +and nice meeting you. Let me thank the the organizer for all the +organization and all the work they are doing to support us. My name is +Adolfo Villafiorita. I'm teaching at the University of Trento. I will +shortly be working at shared.tech, which is a non-profit organization +developing applications to recover surplus food. + +00:00:35.680 --> 00:00:38.600 The reason of the talk today and the +reason I'm here today is to talk about my experience in moving from +Jekyll static website generator to Org Mode. The reason I moved to Org +Mode is to have better support for literate programming on the +websites at the University of Trento, where we make available the +content for the the students. + +00:01:04.720 --> 00:01:08.900 First of all, what is a static website +generator? It is basically a tool which allows you to generate HTML +files out of text files containing basically two types of information: +metadata and content. + +00:01:20.700 --> 00:01:23.119 +Metadata is a +set of key pairs describing the + +00:01:26.159 --> 00:01:28.560 +content of the file, such as the title, + +00:01:28.560 --> 00:01:31.733 +author, tags, and so on and so forth. + +00:01:31.733 --> 00:01:34.560 +The content is what you actually +want to + +00:01:34.560 --> 00:01:37.040 +get published on the Internet in + +00:01:37.040 --> 00:01:38.880 +the HTML file. + +00:01:38.880 --> 00:01:41.439 +Usually the content is written in + +00:01:41.439 --> 00:01:45.800 +some kind of markup language, + +00:01:45.800 --> 00:01:49.759 +such as Markdown or possibly + +00:01:49.759 --> 00:01:53.200 +Org Mode. Jekyll is a very + +00:01:53.200 --> 00:01:57.900 +popular static website generator. + +00:01:57.900 --> 00:01:59.840 +It is written in Ruby. + +00:01:59.840 --> 00:02:03.280 +What it does: it systematically + +00:02:03.280 --> 00:02:06.840 +transforms all the input files + +00:02:06.840 --> 00:02:09.440 +by making the content into + +00:02:09.440 --> 00:02:11.599 +HTML and systematically applying a + +00:02:11.599 --> 00:02:14.000 +template in order to generate the + +00:02:14.000 --> 00:02:17.120 +HTML files, which you can then deploy + +00:02:17.120 --> 00:02:19.840 +on your server of choice to make them + +00:02:19.840 --> 00:02:22.160 +available on the Internet. + +00:02:22.160 --> 00:02:26.160 +One of the features most-- + +00:02:26.160 --> 00:02:27.500 +well, I would say all + +00:02:27.500 --> 00:02:30.239 +static website generators have + +00:02:30.239 --> 00:02:32.560 +is that of being able to + +00:02:32.560 --> 00:02:34.879 +collect the metadata information + +00:02:34.879 --> 00:02:38.400 +of the files being part of + +00:02:38.400 --> 00:02:39.440 +your project. + +00:02:39.440 --> 00:02:45.280 +The reason they do that is because + +00:02:45.280 --> 00:02:47.840 +you sometimes want to generate pages + +00:02:47.840 --> 00:02:49.280 +based on the content + +00:02:49.280 --> 00:02:53.200 +of your projects, + +00:02:53.200 --> 00:02:56.239 +such as, for instance, the list of + +00:02:56.239 --> 00:02:59.040 +posts you have recently published, or + +00:02:59.040 --> 00:03:00.400 +maybe the list of tags + +00:03:00.400 --> 00:03:03.840 +you have defined for your post, + +00:03:03.840 --> 00:03:07.280 +and so on and so forth. + +00:03:07.280 --> 00:03:09.760 +Jekyll gives the possibility of + +00:03:09.760 --> 00:03:12.400 +generating this kind of dynamic + +00:03:12.400 --> 00:03:14.400 +content by using Liquid, + +00:03:14.400 --> 00:03:18.800 +which is a templating language which + +00:03:18.800 --> 00:03:21.840 +looks like this. + +00:03:21.840 --> 00:03:24.879 +So basically, you have all the + +00:03:24.879 --> 00:03:26.879 +constructs you can + +00:03:26.879 --> 00:03:28.800 +expect in a programming language. + +00:03:28.800 --> 00:03:29.920 +This, for instance, + +00:03:29.920 --> 00:03:33.360 +is a for cycle which + +00:03:33.360 --> 00:03:37.440 +iterates over all the posts or the + +00:03:37.440 --> 00:03:39.599 +files in a specific directory of the + +00:03:39.599 --> 00:03:41.040 +Jekyll project. + +00:03:41.040 --> 00:03:45.040 +For each post, it takes the title + +00:03:45.040 --> 00:03:48.400 +and the URL and generates a link. + +00:03:48.400 --> 00:03:52.867 +So Jekyll is nice and sweet, + +00:03:52.867 --> 00:03:55.200 +but over the years + +00:03:55.200 --> 00:03:57.760 +I started using more and more + +00:03:57.760 --> 00:03:59.519 +systematically + +00:03:59.519 --> 00:04:02.000 +Org Mode to write all my files. + +00:04:02.000 --> 00:04:04.833 +I moved from Markdown to Org Mode + +00:04:04.833 --> 00:04:07.200 +I am a long time Emacs user. + +00:04:07.200 --> 00:04:09.167 +I've been using Emacs for 30 years now, + +00:04:09.167 --> 00:04:12.799 +so Org Mode is a more recent discovery, + +00:04:12.799 --> 00:04:17.033 +but it is a very nice discovery I made. + +00:04:17.033 --> 00:04:19.680 +The reason I like Org Mode + +00:04:19.680 --> 00:04:22.320 +is because, for instance, you can write + +00:04:22.320 --> 00:04:24.933 +formulas using MathJax + +00:04:24.933 --> 00:04:26.639 +and you can generate diagrams + +00:04:26.639 --> 00:04:30.320 +or plots with Gnuplot. + +00:04:30.320 --> 00:04:32.240 +Also important is the fact that you have + +00:04:32.240 --> 00:04:34.080 +the possibility of publishing + +00:04:34.080 --> 00:04:39.520 +your documents to multiple backends +such as PDF, + +00:04:39.520 --> 00:04:43.600 +or maybe a Reveal presentation, + +00:04:43.600 --> 00:04:47.199 +or HTML. This is all made possible + +00:04:47.199 --> 00:04:50.479 +by Babel, which is + +00:04:50.479 --> 00:04:52.560 +exactly what we just saw in the + +00:04:52.560 --> 00:04:54.639 +previous talk: + +00:04:54.639 --> 00:04:57.440 +Namely, the possibility of executing a + +00:04:57.440 --> 00:04:59.520 +snippet of code + +00:04:59.520 --> 00:05:02.560 +embedded in in your pages. + +00:05:02.560 --> 00:05:06.400 +Our model can also be used + +00:05:06.400 --> 00:05:09.600 +within Jekyll. In fact, + +00:05:09.600 --> 00:05:13.667 +there is a a nice gem, a nice library, + +00:05:13.667 --> 00:05:17.233 +called jekyll-org which allows you + +00:05:17.233 --> 00:05:19.680 +to use Org Mode files directly + +00:05:19.680 --> 00:05:22.880 +into jekyll. But when you start using + +00:05:22.880 --> 00:05:26.560 +Org Mode... When I started using + +00:05:26.560 --> 00:05:30.560 +Org Mode, I realized I could move + +00:05:30.560 --> 00:05:34.240 +all my workflow, all my publishing + +00:05:34.240 --> 00:05:36.840 +workflow to Emacs. + +00:05:36.840 --> 00:05:41.100 +In fact, Org Mode is also a + +00:05:41.100 --> 00:05:42.880 +static website generator because + +00:05:42.880 --> 00:05:46.240 +it has got the possibility of publishing + +00:05:46.240 --> 00:05:50.880 +projects made of Org Mode files. + +00:05:50.880 --> 00:05:53.840 +One of the nice things about + +00:05:53.840 --> 00:05:56.479 +the publishing features of Org Mode + +00:05:56.479 --> 00:05:58.880 +is that it allows you to define in the + +00:05:58.880 --> 00:06:01.300 +org-publish-project-alist, + +00:06:01.300 --> 00:06:03.199 +all the the components + +00:06:03.199 --> 00:06:05.367 +which are part of your project. + +00:06:05.367 --> 00:06:07.520 +In a sense, it is + +00:06:07.520 --> 00:06:10.479 +also more flexible than Jekyll, + +00:06:10.479 --> 00:06:12.880 +because it also allows you, for instance, + +00:06:12.880 --> 00:06:15.120 +to publish a single file rather + +00:06:15.120 --> 00:06:17.440 +than having to recompile everything + +00:06:17.440 --> 00:06:20.080 +every time you want to publish your + +00:06:20.080 --> 00:06:22.333 +your project to your website. + +00:06:22.333 --> 00:06:25.333 +However, there are some short comments + +00:06:25.333 --> 00:06:29.520 +I would say, or some areas +of improvement. + +00:06:30.400 --> 00:06:33.600 +The first is that support for +templating + +00:06:33.600 --> 00:06:36.639 +is not so obvious as it is + +00:06:36.639 --> 00:06:39.280 +in Jekyll, even though there are some + +00:06:40.560 --> 00:06:44.560 +nice extensions such as org-thtml, + +00:06:44.560 --> 00:06:48.400 +for instance, which allows you to use +templates. + +00:06:48.400 --> 00:06:51.840 +More important to me was the fact that + +00:06:51.840 --> 00:06:54.080 +apparently, there is little support for + +00:06:54.080 --> 00:06:56.133 +the creation of dynamic content + +00:06:56.133 --> 00:06:57.900 +So I was very curious + +00:06:57.900 --> 00:06:59.360 +and very keen to use + +00:06:59.360 --> 00:07:02.800 +Org Mode for publishing my blog + +00:07:02.800 --> 00:07:05.440 +and the courses at the university, + +00:07:05.440 --> 00:07:08.720 +but then I had to find a way + +00:07:08.720 --> 00:07:11.440 +to being able to publish these + +00:07:11.440 --> 00:07:13.599 +dynamic pages, finding some kind of + +00:07:13.599 --> 00:07:16.000 +replacement, so to speak, + +00:07:16.720 --> 00:07:17.900 +for the liquid engine. + +00:07:17.900 --> 00:07:24.160 +The solution was there at hand, +actually, because + +00:07:24.160 --> 00:07:27.280 +basically, I realized I could use Babel + +00:07:27.280 --> 00:07:30.800 +for exactly this purpose. Rather than + +00:07:30.800 --> 00:07:32.720 +using Babel for generating + +00:07:32.720 --> 00:07:35.759 +plots or my other computations + +00:07:35.759 --> 00:07:37.919 +or whatever I was using them for, + +00:07:37.919 --> 00:07:41.039 +I realized I could use Babel to + +00:07:41.039 --> 00:07:45.120 +generate HTML which could be + +00:07:45.120 --> 00:07:49.967 +then published in the project + +00:07:49.967 --> 00:07:53.680 +All I needed to do then + +00:07:53.680 --> 00:07:56.100 +was defining some kind of functions, + +00:07:56.100 --> 00:07:58.319 +some kind of code in order to read + +00:07:58.319 --> 00:08:01.840 +the metadata of all + +00:08:01.840 --> 00:08:04.767 +the Org Mode files of my web project, + +00:08:04.767 --> 00:08:09.680 +so that I could then publish-- + +00:08:09.680 --> 00:08:13.280 +generate the dynamic content. + +00:08:13.280 --> 00:08:18.080 +This is a snippet taken from + +00:08:18.080 --> 00:08:21.759 +one of my HTML projects, + +00:08:21.759 --> 00:08:24.800 +which basically shows the way in which + +00:08:24.800 --> 00:08:27.599 +I generate the list of posts on + +00:08:27.599 --> 00:08:32.560 +my page. It is exactly how the +Liquid that we saw + +00:08:32.560 --> 00:08:35.680 +a couple of slides earlier that +looks like + +00:08:35.680 --> 00:08:39.200 +in Org Mode. + +00:08:39.200 --> 00:08:42.320 +Basically, what I'm doing... +I'm using... + +00:08:42.320 --> 00:08:46.720 +I wrote a Ruby script which + +00:08:46.720 --> 00:08:49.680 +reads all the metadata. So this + +00:08:49.680 --> 00:08:51.040 +highlighted code + +00:08:51.040 --> 00:08:53.100 +basically loads the script + +00:08:53.100 --> 00:08:55.300 +which is stored externally. + +00:08:55.300 --> 00:08:56.800 +Then it collects all the + +00:08:56.800 --> 00:08:58.320 +metadata from the + +00:08:58.320 --> 00:09:00.880 +Org Mode files in the + +00:09:00.880 --> 00:09:02.240 +current directory. + +00:09:02.240 --> 00:09:04.800 +And then the following... The code + +00:09:04.800 --> 00:09:06.480 +you can see here + +00:09:06.480 --> 00:09:09.839 +basically iterates over all the + +00:09:09.839 --> 00:09:12.959 +posts read at the previous step. + +00:09:12.959 --> 00:09:16.399 +It generates + +00:09:16.399 --> 00:09:19.519 +a list with the title + +00:09:19.519 --> 00:09:22.959 +and the URLS, basically + +00:09:22.959 --> 00:09:27.440 +replicating what Jekyll does. + +00:09:27.440 --> 00:09:30.240 +There are some other things + +00:09:30.240 --> 00:09:32.399 +I have to deal with in order to + +00:09:33.200 --> 00:09:36.480 +accommodate my workflow. But that was + +00:09:36.480 --> 00:09:39.200 +relatively easy in the sense that one of + +00:09:39.200 --> 00:09:43.279 +the problems, one of the issues I had to + +00:09:43.279 --> 00:09:45.360 +solve was that of having + +00:09:45.360 --> 00:09:48.480 +a common navigation on all my + +00:09:48.480 --> 00:09:51.040 +pages. That was easily solved + +00:09:51.040 --> 00:09:53.867 +using the #+INCLUDE feature. + +00:09:53.867 --> 00:09:54.959 +So I basically + +00:09:54.959 --> 00:09:56.000 +made available + +00:09:56.000 --> 00:09:57.839 +an #+INCLUDE with all the navigation + +00:09:57.839 --> 00:10:00.560 +which is embedded in all the pages of + +00:10:00.560 --> 00:10:01.839 +my websites + +00:10:01.839 --> 00:10:03.733 +through the #+INCLUDE. + +00:10:03.733 --> 00:10:06.160 +Another nice feature which + +00:10:06.160 --> 00:10:08.560 +Jekyll has is the possibility of + +00:10:08.560 --> 00:10:12.800 +previewing a website before deploying it. + +00:10:13.200 --> 00:10:16.079 +Emacs also has got a node which allows + +00:10:16.079 --> 00:10:21.200 +you to launch a web server. In fact, + +00:10:21.200 --> 00:10:24.320 +I wrote a quick hack + +00:10:24.320 --> 00:10:26.959 +which allows you to + +00:10:26.959 --> 00:10:31.519 +invoke a node on an Org Mode + +00:10:31.519 --> 00:10:34.720 +project, start a local preview, + +00:10:34.720 --> 00:10:37.920 +and then use rsync + +00:10:37.920 --> 00:10:44.839 +in order to deploy the the website. + +00:10:46.240 --> 00:10:48.720 +Five minutes left. More than + +00:10:48.720 --> 00:10:51.200 +enough. Okay. + +00:10:51.200 --> 00:10:52.967 +Thanks. Thank you, thank you very much. + +00:10:52.967 --> 00:10:56.480 +I'm nearly done. So then I can take +some questions. + +00:10:56.480 --> 00:11:00.560 +Just to give you maybe + +00:11:00.560 --> 00:11:03.680 +a slightly more in-depth + +00:11:03.680 --> 00:11:06.480 +view of what the pages look like, + +00:11:06.480 --> 00:11:07.200 +so these are + +00:11:07.200 --> 00:11:11.120 +one of the pages, or the source files + +00:11:11.120 --> 00:11:14.720 +of one of the websites. It is + +00:11:14.720 --> 00:11:18.480 +in literate programming. Basically, + +00:11:18.480 --> 00:11:20.399 +you see there is some metadata here. + +00:11:20.399 --> 00:11:22.640 +I mean this is a regular Org Mode file. + +00:11:22.640 --> 00:11:26.640 +This part here + +00:11:26.640 --> 00:11:29.920 +basically defines some common options + +00:11:29.920 --> 00:11:31.519 +for publication. + +00:11:31.519 --> 00:11:35.920 +These two includes here + +00:11:35.920 --> 00:11:41.120 +put some extra HTML in the head part and + +00:11:41.120 --> 00:11:44.480 +the navigation. Here, as you can see, + +00:11:44.480 --> 00:11:48.079 +is the code generating the + +00:11:48.079 --> 00:11:50.160 +the list in chronological order. It is + +00:11:50.160 --> 00:11:52.240 +slightly more complex than the example I + +00:11:52.240 --> 00:11:53.839 +made in the slide + +00:11:53.839 --> 00:11:56.240 +because there is some more + +00:11:56.240 --> 00:11:59.760 +elaboration to do, including +putting some + +00:11:59.760 --> 00:12:01.839 +Javascript to identify + +00:12:01.839 --> 00:12:05.120 +according to the tags. + +00:12:05.120 --> 00:12:08.160 +To go back to the presentation... + +00:12:11.200 --> 00:12:13.067 +I managed this migration + +00:12:13.067 --> 00:12:14.560 +a few months ago, + +00:12:14.560 --> 00:12:17.680 +and then all my workflow is within + +00:12:17.680 --> 00:12:20.399 +Org Mode and within Emacs. + +00:12:20.399 --> 00:12:23.079 +I'm very happy with it because it's + +00:12:23.079 --> 00:12:26.800 +simplified quite a bit + +00:12:26.800 --> 00:12:28.480 +my publication process. + +00:12:28.480 --> 00:12:31.839 +One of the advantages... Another + +00:12:31.839 --> 00:12:34.240 +advantage... So the first advantage is that + +00:12:34.240 --> 00:12:36.959 +everything is in Org Mode and Emacs. + +00:12:36.959 --> 00:12:38.160 +Second advantage + +00:12:38.160 --> 00:12:41.680 +is that everything is based on the + +00:12:41.680 --> 00:12:44.880 +standard machinery provided by Org Mode. + +00:12:44.880 --> 00:12:47.760 +So in a sense, it is + +00:12:47.760 --> 00:12:50.079 +more robust with respect to + +00:12:50.079 --> 00:12:53.040 +dependencies, possible errors, and so + +00:12:53.040 --> 00:12:54.320 +on and so forth. + +00:12:54.320 --> 00:12:56.639 +The fact that Org Mode + +00:12:56.639 --> 00:12:58.240 +allows you to publish + +00:12:58.240 --> 00:13:00.880 +a single file in a project is also + +00:13:00.880 --> 00:13:03.839 +very interesting because + +00:13:03.839 --> 00:13:07.839 +it allows to be more robust to + +00:13:07.839 --> 00:13:11.040 +problems you might introduce when + +00:13:11.040 --> 00:13:14.959 +you're changing--when I'm changing the +setup. + +00:13:14.959 --> 00:13:16.880 +Another interesting thing which I + +00:13:16.880 --> 00:13:21.519 +realized that I could have is that + +00:13:21.519 --> 00:13:23.600 +in a sense, the specification of the + +00:13:23.600 --> 00:13:28.480 +website can be embedded in the website +itself. + +00:13:28.480 --> 00:13:30.800 +In a sense this is some kind of + +00:13:30.800 --> 00:13:31.839 +self-documenting... + +00:13:31.839 --> 00:13:35.120 +It's a way of self-documenting + +00:13:35.120 --> 00:13:36.600 +what I'm actually doing. + +00:13:36.600 --> 00:13:44.133 +For instance, here on my website, + +00:13:44.133 --> 00:13:46.399 +you can see the + +00:13:46.399 --> 00:13:48.240 +specification of the + +00:13:48.240 --> 00:13:51.519 +project which is loaded + +00:13:51.519 --> 00:13:53.933 +from my initialization file, + +00:13:53.933 --> 00:13:56.320 +but then it is also published + +00:13:56.320 --> 00:13:59.440 +together with my home page. It lives + +00:13:59.440 --> 00:14:01.360 +with the repository where + +00:14:01.360 --> 00:14:05.360 +I keep all the sources of my website, + +00:14:05.360 --> 00:14:08.079 +which is kind of nice because it + +00:14:08.079 --> 00:14:09.839 +basically isolates + +00:14:09.839 --> 00:14:14.079 +everything in a single place. + +00:14:14.079 --> 00:14:16.880 +So there are some examples. I'm + +00:14:16.880 --> 00:14:19.433 +showing them more because of the + +00:14:19.433 --> 00:14:21.760 +source code which + +00:14:21.760 --> 00:14:25.519 +you can grab from the git repositories + +00:14:25.519 --> 00:14:26.933 +if you are interested. + +00:14:26.933 --> 00:14:28.399 +Of course I'm also available + +00:14:28.399 --> 00:14:31.600 +to provide some support and help + +00:14:31.600 --> 00:14:32.959 +if you are interested + +00:14:32.959 --> 00:14:34.480 +in this kind of stuff. + +00:14:34.480 --> 00:14:37.760 +The the next step for me will be that of + +00:14:37.760 --> 00:14:41.600 +trying, making this kind of +machinery available + +00:14:41.600 --> 00:14:45.199 +for more general use at the moment. + +00:14:45.199 --> 00:14:47.120 +If you are interested in trying out my + +00:14:47.120 --> 00:14:48.800 +suggestion, grabbing the + +00:14:48.800 --> 00:14:51.933 +sources for one of the websites + +00:14:51.933 --> 00:14:54.700 +to seehow they look like, + +00:14:54.700 --> 00:14:56.720 +and maybe try and + +00:14:56.720 --> 00:15:00.160 +customize it for your purposes... + +00:15:00.160 --> 00:15:03.839 +This is basically the content of my talk. + +00:15:03.839 --> 00:15:06.959 +I'm open to questions and thank you + +00:15:06.959 --> 00:15:10.880 +for your attention. + +00:15:10.880 --> 00:15:12.880 +(Amin: Thank you very much, Adolfo, for your + +00:15:12.880 --> 00:15:14.480 +awesome presentation. + +00:15:14.480 --> 00:15:17.360 +I think we have time for maybe like + +00:15:17.360 --> 00:15:19.360 +one or two questions, + +00:15:19.360 --> 00:15:21.279 +and then the rest maybe you could + +00:15:21.279 --> 00:15:26.639 +take up after the stream.) + +00:15:26.639 --> 00:15:28.033 +Adolfo: What should we do? + +00:15:28.033 --> 00:15:30.000 +(Amin: Would you like me + +00:15:30.000 --> 00:15:31.839 +to read you the questions?) + +00:15:31.839 --> 00:15:35.199 +Adolfo: Yeah, probably better because + +00:15:35.199 --> 00:15:36.700 +I'm kind of lost there. + +00:15:36.700 --> 00:15:40.399 +(Amin: Okay, no problem. + +00:15:40.399 --> 00:15:42.480 +So someone asks, "Do you have any + +00:15:42.480 --> 00:15:45.440 +opinion on Firn?") + +00:15:45.440 --> 00:15:48.639 +Adolfo: Firn.

I'm Zachary Kanfer, and this is waving at repetitive +repetitive repetitive music. Over quarantine, I've been bored, and I +found this Android app that has a bunch of mini-games, one of which +lets you compose music. And it works, but I want a little bit more +functionality than it offers, it's not very flexible. So, I thought +what if I made this, and what programs could I make this in that are +really flexible, are really customizable. Emacs. So, I looked into +it, and Emacs can play sounds, right? If you hit control g a couple of +times, you'll hear like an error tone, and it turns out that, that is +actually playing a WAVE file, but what's a WAVE file? + +(00:58) Well, it turns out that WAVE is a musical file format, or +really an annoying file format. So, data in it can be an unsigned +integer or a signed integer, it's not consistent, and it's +little-endian by default which is not the way I like to think about +it. Now, you can set a WAVE file to be big-endian, but if you do +that, Emacs can't play it. So, little-endian it is. There's also +duplicate data fields. Here are some fields that are fine, but then +there's a fourth field that's calculated based on multiplying two of +the other ones together, and then there's another data field that's… +you multiply those three ones together. So, it's just repetitive and +unnecessary, but you have to do it, or it's not a valid WAVE file. +Also, the last part of the file is described as data or as one website +I found said, the actual sound data. + +(02:04) Now, I don't know about you but when I see that, I think, what +is data? It turns out that sound is just a wave, and the data is just +a bunch of measurements of the height of that wave forming each +sample. So, this wave starts at 8 goes 9, 11, 13, 14, 15, and then +back down. If you just take those measurements, those numbers, put +them in a file, that's all your data is. + +(02:35) All right. Let's go to a demo of my program. So, this is what +zmusic looks like. The blue highlighted row is a single beat, there's +16 of them in this zmusic file, and each dash in the row is a single +note increasing…, starting really low all the way on the left and +going up as we go to the right. So, if we started playing, we won't +hear anything, but we'll see the highlighted beat is the currently +playing one, and we see that it loops. So, we can stop it, and now we +can click to add some notes. [Music] Even more than one note at the +same time works. [Music] And we can even add notes while it's +playing. [Music] + +(04:08) Okay, here are some other features that I didn't have time to +demo. So, you can save the music to a file, and this is interesting +because normally if there's no note in a beat, we just don't play that +beat, but if you're writing to a file you have to put something in, so +when it's playing it knows to not make a sound there. We can also use +different scales. We're using the minor pentatonic in the demo, but +you can use the major scale the minor scale or anything else. And +there's also keyboard support, but it sounds really bad, and I'll +explain why later. + +(04:48) Here are some things I learned while writing zmusic. Emacs +has buttons which are great as long as you don't put two of them right +next to each other. So, if you do that, mousing over one of them +highlights both of them. Now, that's because a button is really just +a series of characters with a text property to highlight them. So, +the fix is, you put another character between the two buttons, then +mousing over one of them only highlights the one you want, but even +this doesn't work really great for zmusic, because zmusic has a lot of +very small buttons in a row. So, it's really easy to accidentally put +your cursor over the space and click on that instead of the button. +So, I looked into unicode, and I found this character called a +zero-width space. So, we should be able to put that between buttons +and not be able to accidentally click on it. Unfortunately, a +zero-width space isn't actually zero width. If we put a hundred of +them between two other characters, you can see there's space there, +and I think what's happening is, the space is zero width but then +Emacs `put` uses one pixel between each pair of characters for the +cursor, so it's almost zero width. Some ways to play sound that don't +quite work! `play-sound` plays music, but it blocks, you can't do +things like, set other notes or even pause the music. And if you +throw it into async.el, it's silent, and I don't know why. So, the +solution I went with is taking that WAVE file, ran into the file +system, and then shelling out to a native executable to play the +sound. And that works fine as long as you only do it once, because if +you do it a couple of times at the same time like if you have a chord, +and you want to play three notes simultaneously, you get this weird +interference, and that's actually why the keyboard from before didn't +work. Also, side effects have this unexpected impact, when you saw +the demo it was running pretty smoothly, but if I just add one message +statement every beat for debugging purposes, I was getting lag and +jitter. + +(07:03) Here's the one thing I learned about music theory, music +theory is not easy to program. I was looking around to see what +concepts we can use to code the scales, to code the notes, the first +thing that I saw is scale degrees, and this when I looked into it, you +don't want to program in scale degrees. So, you see we have the +first, second, third, fourth, fifth, sixth, seventh but then it wraps +around. That octave up is also a first, and that's because both of +those notes are C, so that didn't work, and also you couldn't really +easily specify a flat or sharp. You could say a sharp third or you +know, a flat seventh or whatever, but then you kind of have these two +pieces of data that indicate the note, and I didn't love that. + +(07:55) So, I looked again, and I found intervals, and then I thought +about it, and you don't really want to program in intervals either. +It fixes some of the problems with scale degrees, you see, all the way +on the right you have an octave, so you wrap to 8, and you go 9, 10 +and that works. But you solve the same problem, you see you have a +major third but below we also have a minor third, so you saw that +problem of having two pieces of information. + +(08:20) So, I thought about it. Music is really frequencies. Like an A +is 440 hertz. So, at a low level that's what we're going to do, we're +just going to use frequencies. And then at the one level above that, +that's a little bit easier for humans to think about, we're going to +use semitones up from the root, which is kind of like scale degrees, +but instead of just counting each note as one more, we're going to say +how many semitones up it is. So, if there's a sharp between two +notes, that's going to be two steps up instead of just one. And then +we translate those two frequencies, so your A is 440 hertz, another +note might be 613.5, or whatever, and that's we use the low level to +play. + +(09:02) Some future work I have, I want to add some drums. I want to +make that keyboard actually work, and computers and synthesizers are +the only place you hear a pure sine wave like the one we have here, so +I want to add overtones or other octaves above it just to make it +sound a little bit more realistic. I've put notes references and the +source code up at <https://zck.org/emacsconf2020> [updated]. I'm one +of the organizers of EmacsNYC check that out. And if you take a look +or have any thoughts, I'd love to hear them, and thanks so much for +coming to my talk. + +<!-- /transcript --> + + +<!-- transcript: 2020/subtitles/emacsconf-2020--35-waveing-at-repetitive-repetitive-repetitive-music-zmusic--questions--zachary-kanfer.vtt --> + +<a name="transcript-questions"></a> +# Transcript: Q&A + +(00:09) Okay, yeah, so I'm Zachary Kanfer, let's go to the +questions. The first question, "Why do we go top to bottom for time +progression, and left to right for low to high?" Interesting, I +think…, so the initial thing I was copying, that initial app work this +way, and yeah, I mean, certainly traditional music, you know, on a +staff does go left to right like this. I mean, going top to bottom +does make it easier to add more beats without having to wrap, but +certainly that could be managed. Yeah, I had not really thought about +it, but it is definitely something worth looking into. + +(01:21) Two, "Will you play us another song?" Not now, I can make some +recordings of it, or certainly you can try it. I couldn't quite get +the microphone and the webcam and everything to work with the sound +playing now. So, I can record some. Also, I have put a link in the +Etherpad, <https://zck.org/emacsconf2020> [updated], where you can go +and get the source, and you can try it yourself. There's no +dependencies needed, so it's just all in Emacs. So, please, you know, +try it yourself. + +(01:57) "Any chance for an Emacs tracker or mod player?" I don't +really know what a mod player or tracker are, but I mean, I'm sure +that would be cool, maybe there's one on now, but I don't know. + +(02:11) My musical background. So, I've played various instruments +since about the third grade. Started recorder, play cello, I play +guitar now. But yeah, so just kind of random instruments, and I guess +kind of some of those things influence how I think about music. + +(02:33) "Are there any open source musical management sample libraries +that could be used?" Good question, I'm sure there are, I don't know +any of that integrate really well with Emacs. One of the cool things +that I liked about this is that there are no dependencies, you know, +you don't need any external program to generate the music. I mean, it +does shell out to to play, but that should be able to be done on any +operating system, as always, you have something that can play WAVE +files, but yeah, it is interesting to kind of try the different sounds +and different tones that you could get with different instruments. + +(03:14) Have I written any actual songs? Nothing super well put +together, I kind of just been playing around with this. It's kind of… +making this was one of those things where once I made it, I was like, +okay, now I can play with it, and I did a little bit, and was like, I +don't know if I feel like it right now. You know, which I've found +that to be the case with some things that I've implemented in Emacs +where it's… I make it, and then it's the kind of some of the desire to +use it all the time goes away, but I'm sure I'll circle back around at +some point especially kind of maybe once I add in different tones or +something. + +(03:54) I guess a similar question for pre-recorded sounds. Yeah, I +mean, if it's… part of what I did, what I wrote was a WAVE generation +library, so, if you kind of have the data, you could use those and +chop them up and take certain lengths of them and make a WAVE file, so +it's not plug and play right now, but you could certainly add those +notes to do it. + +(04:19) "Any MIDI mapping possibilities?" I haven't looked into it, +but I'm sure you definitely could output to MIDI which is another +benefit of having that multiple layers with the top layer is just, you +know, if the root note is this, we're just two semitones up or seven +semitones up or whatever it is. It should be relatively simple to +kind of switch out that layer underneath from WAVE to MIDI or other +things. + +(04:44) "What were some of the challenges with writing a special mode +for Emacs?" Interested in getting into this, not sure where to start. +This isn't the first mode I've written, so that's right…, certainly +that helps. I actually… I have a video that we recorded it as part of +EmacsNYC on making a major mode. That's basically starts from +nothing, and kind of builds up to an implementation of tic-tac-toe, +but so it kind of goes into printing things out and buttons and making +the mode. I mean, one of the best parts about Emacs is, because it's +so configurable and so introspectible, you can start pretty simply, +and just kind of ask Emacs about things, and then make one little +change. It's really… it's not that bad, so, I'll try to throw a link +up on that page I put up, or please email me for whoever asked this +question to get a link to that video, or just look at the source code +of this or any other major mode. Emacs makes it pretty easy to extend +major modes. + +(05:54) And I think that's the last question in the Etherpad, so, +thanks so much everybody for coming. (Amin: Thank you so much to +Zachary for your awesome talk, and for doing live questions. Thank +you.) Thank you.

In 1976, I -developed the first Emacs editor with some help from Guy Steele. -Then, shortly after starting to develop the GNU operating system in -1984, I wanted an Emacs editor for it. So I started writing GNU Emacs -in September 1984. - -(00:29) Several years ago we decided to move many of the Emacs Lisp -packages outside the core Emacs distribution into a separate package -archive that we call the Emacs Lisp package archive ELPA. There were -two main reasons for this. One is to make the Emacs distribution -smaller so every user wouldn't have to get all the packages and -install all the packages. And the other reason was to make it possible -to release individual packages separately from Emacs releases. - -(01:08) Now, at that point somehow we decided to support loading -packages from a variety of different Emacs Lisp package archives and -ours would be called the GNU ELPA, but ELPA could be any other. Now, I -think that naming was a mistake. We should have meant, we should have -decided that ELPA referred to our package archive and any other -package archive should be called some other name. Oh, well! Uh this is -a mistake I believe, because it leads to a lot of confusion it would -have been clearer if we had uh used the other naming. - -(01:55) Because the difference between having a package in core Emacs -and having it in GNU ELPA, is purely a practical convenience matter. -Convenience of distribution and convenience of maintenance. We wanted -to be able to move packages between the two whenever that was -convenient. So, to make that possible we insisted on getting copyright -assignments for packages in GNU ELPA just the same way we do for -packages in core Emacs. - -(02:31) Having the facility for installing packages from package -archives, led to a tremendous boost in the development and release of -Emacs packages. Unfortunately there was a problem with the way that -was done. For the most part, the developers of these packages wouldn't -even tell us about them. They posted them in another package archive -where we didn't know about them and (where they) no attempt was made -to try to fit them into Emacs so that they could make sense as parts -of the Emacs distribution. This led to both moral problems, packages -that depended on non-free software in order to be usable and technical -problems because the developers of those packages didn't coordinate -with us about how to make it useful and convenient and clean to have -them in Emacs. - -(03:36) So, the idea of NonGNU ELPA is an effort to smooth these -things out. The fundamental plan of NonGNU ELPA is that, we won't ask -for copyright assignments for those packages. So, we won't be able to -put them into core Emacs; at least not easily, but we will have some -control over how we distribute them. We can put any package into -NonGNU ELPA as long as it's free software. If we like it we can set up -that way for users to get it. We could put the package in exactly as -it is if there's no problem at all with it. We can make an arrangement -with the package's developers to work on it with us and maintain it -directly for distribution by NonGNU ELPA but if they are not -interested we can put it in ourselves and if we need to make any -changes we can do so. - -(04:52) So, NonGNU ELPA is not meant to be just a way that others can -distribute their packages. It's meant at least in a minimal technical -sense to work with GNU Emacs, and we'll make changes if necessary so -that it works smoothly with Emacs. And this means that we're going to -maintain it differently from GNU ELPA. Well, GNU ELPA is hosted in a -way that is actually rather inconvenient. It is one single Git -repository. And so anybody that has access to write it can write any -part of it. There are many different packages in there maintained by -different people, and we have no way to give each one of them access -to per own package and not to the others. Well, with NonGNU ELPA we -plan to fix that. The idea is to have a single Git repository where -you can download various packages from. But, they won't be maintained -there. Each of those packages will be copied automatically from some -other place. Probably some other repository where the right people -have access to work on it. And this way we can avoid giving a gigantic -number of people access to every part of it. So far NonGNU ELPA is -just a plan, we need people to implement the plan. So, if you would -like to help please write to me. I think this is a very important step -for progress and it's got to be implemented.

Oh. It doesn't work. Sorry. +I want... + +00:04:08.156 --> 00:04:13.056 +I have my whole operating system + +00:04:13.056 --> 00:04:15.589 +defined in a few Nix files. + +00:04:15.589 --> 00:04:18.689 +For example, here you saw the file + +00:04:18.689 --> 00:04:22.522 +which defines some variables for my environment + +00:04:22.522 --> 00:04:24.256 +and then a few more files + +00:04:24.256 --> 00:04:25.722 +for different programs. + +00:04:25.722 --> 00:04:30.056 +There is a folder which contains all +Emacs-related configuration. + +00:04:30.056 --> 00:04:36.989 +Also, there are package definitions +defined in Nix package repositories + +00:04:36.989 --> 00:04:42.522 +which is also included for the function +which generates + +00:04:42.522 --> 00:04:44.556 +the operating system. + +00:04:44.556 --> 00:04:47.622 +Getting all my configurations +written in Nix language + +00:04:47.622 --> 00:04:51.174 +and a few firewalls in ?? languages, + +00:04:51.174 --> 00:04:54.700 +everything is gathered together, + +00:04:54.700 --> 00:04:56.722 +and from that input + +00:04:56.722 --> 00:04:58.322 +and only from that input, + +00:04:58.322 --> 00:05:00.489 +the new operating system is built. + +00:05:00.489 --> 00:05:03.856 +Emacs now is a part of this operating system. + +00:05:03.856 --> 00:05:08.422 +I can distribute this Emacs configuration + +00:05:08.422 --> 00:05:11.689 +with all the environment that I want. + +00:05:11.689 --> 00:05:18.389 +Practical so far. Let's clarify which +problems does it solve. + +00:05:18.389 --> 00:05:21.756 +First of all, the integration problem. + +00:05:21.756 --> 00:05:27.389 +For example, a few minutes ago, you saw +that I changed one variable. + +00:05:27.389 --> 00:05:31.348 +That was to update... The first one, for +my terminal, + +00:05:31.348 --> 00:05:33.889 +and the second one, for my Emacs. + +00:05:33.889 --> 00:05:40.322 +It's pretty good that a few different +programs can share some data. + +00:05:40.322 --> 00:05:43.822 +For example, you can have one of them +for every application, + +00:05:43.822 --> 00:05:45.222 +or something like that + +00:05:45.222 --> 00:05:48.356 +and you change only one value in one place + +00:05:48.356 --> 00:05:50.789 +and the whole operating system is updated. + +00:05:50.789 --> 00:05:56.422 +Also, another problem is reproducibility. + +00:05:56.422 --> 00:06:00.156 + + +00:06:00.156 --> 00:06:06.600 +For example, when you install +your new instance of Emacs + +00:06:06.600 --> 00:06:11.089 +on your laptop or something like that, + +00:06:11.089 --> 00:06:14.289 +you can be sure that you will get the +same package versions + +00:06:14.289 --> 00:06:17.189 +and you can be sure that the +configuration of your work + +00:06:17.189 --> 00:06:20.856 +results in newly-updated or +newly-installed packages. + +00:06:20.856 --> 00:06:25.056 +Also, if you update packages + +00:06:25.056 --> 00:06:27.656 +sometimes it's hard to revert, + +00:06:27.656 --> 00:06:36.289 +because it's the way your package +manager almost every time works. + +00:06:36.289 --> 00:06:38.722 +You're just getting the latest +available packages. + +00:06:38.722 --> 00:06:43.256 +If they are broken, you need to wait for +the maintainer to update them. + +00:06:43.256 --> 00:06:50.989 +And also, your basic configuration +almost always doesn't contain + +00:06:50.989 --> 00:06:56.156 +any native dependencies, like +executables or something else. + +00:06:56.156 --> 00:07:00.689 +Recently, I saw some attempts to make it +possible to + +00:07:00.689 --> 00:07:03.089 +use use-package for those needs, + +00:07:03.089 --> 00:07:06.356 +like ensuring native dependencies +or something like that. + +00:07:06.356 --> 00:07:11.134 +It's obviously... If +your configuration isn't reproducible + +00:07:11.134 --> 00:07:15.322 +and it doesn't have +your whole environment, + +00:07:15.322 --> 00:07:19.522 +placed in one repository, + +00:07:19.522 --> 00:07:22.322 +it's very hard to share such +configuration. + +00:07:22.322 --> 00:07:27.089 +You can share part of your configuration +and some instruction + +00:07:27.089 --> 00:07:32.222 +how to get a similar environment, +but it doesn't always work. + +00:07:32.222 --> 00:07:39.656 +Let's go closer to actually Emacs +configuration itself. + +00:07:39.656 --> 00:07:45.306 +I had some experience with Spacemacs and +Doom Emacs distributions. + +00:07:45.306 --> 00:07:50.414 +I also watched a lot of videos and +articles by Protesilaos + +00:07:50.414 --> 00:07:56.756 +and a lot of other custom configurations +of many different cool people. + +00:07:56.756 --> 00:08:03.039 +And also I was inspired by use-package + +00:08:03.039 --> 00:08:10.839 +and decided that I will create a folding +structure for my Emacs configuration. + +00:08:10.839 --> 00:08:16.172 +I will be using subconfigs. It's almost +the same as layers in Spacemacs, + +00:08:16.172 --> 00:08:20.972 +or modules in Doom Emacs, which are +self-contained. + +00:08:20.972 --> 00:08:26.287 +They contain Emacs Lisp code which +configures all packages necessary + +00:08:26.287 --> 00:08:28.789 +for this part of configuration. + +00:08:28.789 --> 00:08:33.493 +It contains all Emacs dependencies like +Emacs packages. + +00:08:33.493 --> 00:08:36.572 +It contains all native dependencies + +00:08:36.572 --> 00:08:40.039 +like binaries or maybe info pages or +something like that. + +00:08:40.039 --> 00:08:45.115 +It also contains variables +that can be shared between + +00:08:45.115 --> 00:08:47.989 +Emacs and other applications, + +00:08:47.989 --> 00:08:52.072 +and it can contain service +or system definitions + +00:08:52.072 --> 00:08:56.072 +which configure your systemd service or +something like that + +00:08:56.072 --> 00:09:01.306 +that you use in your workflow. For +example, for synchronizing your e-mails. + +00:09:01.306 --> 00:09:06.239 +Let's start from just the example + +00:09:06.239 --> 00:09:16.618 +that I already am...

It will be copied to +that .emacs.d directory later + +00:09:33.006 --> 00:09:37.306 +with some exceptions that + +00:09:37.306 --> 00:09:40.789 +it will replace the Nix dir and a +symlink will be created to it. + +00:09:40.789 --> 00:09:47.889 +I have use-package-init.el. +It's part of configuration + +00:09:47.889 --> 00:09:51.522 +that will be on top of everything + +00:09:51.522 --> 00:09:55.589 +to be able to use use-package in my +subconfigurations. + +00:09:55.589 --> 00:10:01.156 +And actually some Nix code to glue +everything up + +00:10:01.156 --> 00:10:06.922 +and config dirs which contain all my subconfigs. + +00:10:06.922 --> 00:10:11.389 +Let's start from faces subconfig. + +00:10:11.389 --> 00:10:14.556 +Let's start from config.el + +00:10:14.556 --> 00:10:20.022 +which can be familiar for many people. + +00:10:20.022 --> 00:10:23.556 +Just use-package definition +for faces package + +00:10:23.556 --> 00:10:24.122 +and some configuration for it + +00:10:24.122 --> 00:10:29.589 +which are setting some attributes. + +00:10:29.589 --> 00:10:32.156 +It reads some variables. + +00:10:32.156 --> 00:10:36.922 +Those variables are actually defined in +a different place. + +00:10:36.922 --> 00:10:44.422 +If I open default.nix file, you can see +that it contains + +00:10:44.422 --> 00:10:52.689 +the definition or subconfig, and it +should contain a definition of variables + +00:10:52.689 --> 00:10:55.322 +that it uses by...

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

Features in eev Look + +00:00:09.519 --> 00:00:11.599 +Like Five Minute Hacks." + +00:00:11.599 --> 00:00:15.280 +This is a presentation at the +EmacsConf 2020 + +00:00:15.280 --> 00:00:23.199 +happening on November 28 and 29, 2020. + +00:00:23.199 --> 00:00:25.519 +So this is part one of the presentation. + +00:00:25.519 --> 00:00:27.680 +Here I'm going to explain + +00:00:27.680 --> 00:00:29.840 +some ideas that are prerequisites for + +00:00:29.840 --> 00:00:32.320 +understanding the rest of the +presentation. + +00:00:32.320 --> 00:00:35.440 +The three main keys of eev are + +00:00:35.440 --> 00:00:37.920 +M-e, M-k, and M-j. +I'm going to start by + +00:00:37.920 --> 00:00:42.079 +explaining M-e and M-k. + +00:00:42.079 --> 00:00:44.960 +M-e is used to follow hyperlinks. + +00:00:44.960 --> 00:00:47.592 +Technically, it is essentially + +00:00:47.592 --> 00:00:49.345 +just a C-e to move to + +00:00:49.345 --> 00:00:50.402 +the end of the line, + +00:00:50.402 --> 00:00:53.918 +and then a C-x C-e to +execute this, + +00:00:53.918 --> 00:00:58.960 +the sexp before point at +the end of the line. + +00:00:58.960 --> 00:01:00.879 +And the thing is that Emacs comes with + +00:01:00.879 --> 00:01:02.479 +many functions that can be + +00:01:02.479 --> 00:01:05.040 +used as sexp hyperlinks. + +00:01:05.040 --> 00:01:07.540 +We can consider that they point to +somewhere. + +00:01:07.540 --> 00:01:09.040 +I'm going to refer to that as + +00:01:09.040 --> 00:01:11.411 +the target of the hyperlink. + +00:01:11.411 --> 00:01:12.960 +If we execute this + +00:01:12.960 --> 00:01:15.759 +sexp hyperlinks, we coul 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 the manpage 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 killing the current buffer + +00:01:29.840 --> 00:01:31.537 +that the hyperlink created: + +00:01:31.537 --> 00:01:34.400 +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 --> 00:01:52.840 +we have to either click here +or type C-x 5 0. + +00:01:54.880 --> 00:01:57.120 +So here are some examples of + +00:01:57.120 --> 00:01:58.726 +sexp hyperlinks using + +00:01:58.726 --> 00:02:00.640 +standard Emacs functions. + +00:02:00.640 --> 00:02:03.188 +This third one is badly behaved + +00:02:03.188 --> 00:02:04.880 +in a different way. + +00:02:04.880 --> 00:02:08.554 +If executed, the target is created + +00:02:08.554 --> 00:02:11.006 +in the same window as we are now, + +00:02:11.006 --> 00:02:14.312 +but it also shows a lot of +garbage + +00:02:14.312 --> 00:02:15.797 +here in the echo area, + +00:02:15.797 --> 00:02:23.280 +so the current frame becomes +a bit messy. + +00:02:23.280 --> 00:02:25.728 +And well, one of the first things + +00:02:25.728 --> 00:02:28.319 +that I did when I was creating eev + +00:02:28.319 --> 00:02:30.720 +many many years ago was that I created + +00:02:30.720 --> 00:02:33.380 +variants of all these functions + +00:02:33.380 --> 00:02:36.640 +that were better behaved. + +00:02:36.640 --> 00:02:39.200 +They were better behaved in two +senses. + +00:02:39.200 --> 00:02:40.839 +The obvious one was that + +00:02:40.839 --> 00:02:43.680 +they all created the target + +00:02:43.680 --> 00:02:45.246 +in the same window as before, + +00:02:45.246 --> 00:02:48.720 +so I could go back by just typing M-k + +00:02:48.720 --> 00:02:52.879 +which has essentially just killed this +buffer. + +00:02:52.879 --> 00:02:56.480 +I also implemented something extra that + +00:02:56.480 --> 00:02:59.040 +are the postback lists. + +00:02:59.040 --> 00:03:03.599 +For example, these extra arguments here +are a postback list. + +00:03:03.599 --> 00:03:06.080 +These extra arguments specify + +00:03:06.080 --> 00:03:09.599 +position and the target buffer. + +00:03:09.599 --> 00:03:14.337 +In this example, +this postback list means: + +00:03:14.337 --> 00:03:18.239 +starting from the beginning of +the buffer, + +00:03:18.239 --> 00:03:22.757 +search for the first occurrence +of this string after that, + +00:03:22.757 --> 00:03:24.754 +after the beginning +of the buffer, + +00:03:24.754 --> 00:03:27.662 +and then search for +the first occurrence + +00:03:27.662 --> 00:03:33.760 +of this string after that. + +00:03:33.760 --> 00:03:36.070 +eev also defines some hyperlinks + +00:03:36.070 --> 00:03:38.799 +that do not create new buffers. + +00:03:38.799 --> 00:03:40.879 +Here is the first example. + +00:03:40.879 --> 00:03:42.971 +If I execute this one, + +00:03:42.971 --> 00:03:45.920 +this one is a hyperlink + +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, + +00:03:50.720 --> 00:03:52.623 +but instead of showing the result + +00:03:52.623 --> 00:03:53.767 +in the new buffer, + +00:03:53.767 --> 00:03:55.475 +the result is shown +here. + +00:03:55.475 --> 00:03:58.959 +So, if I execute this hyperlink, + +00:03:58.959 --> 00:04:01.634 +the result of date, the output of date, + +00:04:01.634 --> 00:04:03.339 +is shown in the echo area. + +00:04:03.339 --> 00:04:07.120 +And if executed again, + +00:04:07.120 --> 00:04:08.673 +it shows the result again, + +00:04:08.673 --> 00:04:09.519 +and the result + +00:04:09.519 --> 00:04:11.519 +changes every second. + +00:04:11.519 --> 00:04:18.720 +So this is a variant of find-sh. + +00:04:18.720 --> 00:04:21.840 +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 +Here is an example of a hyperlink + +00:04:35.919 --> 00:04:39.173 +that calls an external program. + +00:04:39.173 --> 00:04:41.280 +If I execute this, + +00:04:41.280 --> 00:04:43.604 +it calls Google Chrome to open + +00:04:43.604 --> 00:04:46.639 +a certain URL. + +00:04:46.639 --> 00:04:51.520 +Here it is. Let's go back to Emacs. + +00:04:51.520 --> 00:04:55.280 +If I execute this hyperlink here, + +00:04:55.280 --> 00:04:57.986 +it invokes my favorite PDF viewer + +00:04:57.986 --> 00:05:02.560 +which is 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 these other arguments + +00:05:10.880 --> 00:05:15.199 +are ignored. Let me show how it works. + +00:05:15.199 --> 00:05:20.160 +Here it is. This is an excerpt from a +book. + +00:05:20.160 --> 00:05:22.639 +So page 3 in the pdf corresponds to + +00:05:22.639 --> 00:05:26.400 +page 113 in the book. + +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 pdftotext on + +00:05:34.560 --> 00:05:36.479 +this PDF here, + +00:05:36.479 --> 00:05:39.600 +and Emacs takes the output of + +00:05:39.600 --> 00:05:42.880 +running pdftotext on this pdf here + +00:05:42.880 --> 00:05:45.301 +and displays it in a buffer. + +00:05:45.301 --> 00:05:47.280 +Now this postback list + +00:05:47.280 --> 00:05:49.651 +is interpreted in a different way. + +00:05:49.651 --> 00:05:51.280 +This thing is interpreted + +00:05:51.280 --> 00:05:53.425 +as a number of a page, + +00:05:53.425 --> 00:05:55.548 +and Emacs goes to page three + +00:05:55.548 --> 00:05:57.520 +by counting form feeds in + +00:05:57.520 --> 00:06:00.370 +the converted version of the PDF + +00:06:00.370 --> 00:06:03.039 +and then it 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 --> 00:06:09.169 +to see what happens. +Here it is. + +00:06:09.169 --> 00:06:14.800 +I opened the same page +as before. + +00:06:14.800 --> 00:06:18.400 +It starts with lecture one. + +00:06:18.400 --> 00:06:20.720 +So the other hyperlink searched for this + +00:06:20.720 --> 00:06:25.520 +string and for this string here. + +00:06:25.520 --> 00:06:30.400 +This thing here is a hyperlink +to video, + +00:06:30.400 --> 00:06:31.644 +and when I execute it, + +00:06:31.644 --> 00:06:34.560 +it's going to open this video here + +00:06:34.560 --> 00:06:37.759 +at this timestamp. Let's see. + +00:06:37.759 --> 00:06:49.440 +1, 2, 3. 1, 2, 3. +That's the way to do it. + +00:06:49.440 --> 00:06:51.956 +And also some hyperlinks + +00:06:51.956 --> 00:06:53.680 +that I defined, + +00:06:53.680 --> 00:06:55.940 +they don't work like + +00:06:55.940 --> 00:06:58.160 +usual 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 --> 00:07:14.960 +just do something to change +the current page. + +00:07:14.960 --> 00:07:17.312 +If I execute this, the action + +00:07:17.312 --> 00:07:22.240 +of this function eek is to... + +00:07:22.240 --> 00:07:25.423 +It interprets this string +as a series of keys + +00:07:25.423 --> 00:07:30.051 +and it acts as if the user had +typed all these keys. + +00:07:30.051 --> 00:07:32.706 +So if executed, I get a hello + +00:07:32.706 --> 00:07:34.400 +in the next 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 sexp here, at this moment, though it's + +00:07:54.879 --> 00:07:55.759 +not defined. + +00:07:55.759 --> 00:07:57.919 +And if I execute this, Emacs is going to + +00:07:57.919 --> 00:08:00.000 +show me a message saying + +00:08:00.000 --> 00:08:03.599 +symbol as 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 defun, + +00:08:09.520 --> 00:08:12.960 +the action of this function o here + +00:08:12.960 --> 00:08:18.960 +is to run this, which opens a certain +directory. + +00:08:18.960 --> 00:08:21.840 +Let me go back. Here is another + +00:08:21.840 --> 00:08:23.039 +button that defines + +00:08:23.039 --> 00:08:25.489 +several functions at the same time. + +00:08:25.489 --> 00:08:32.320 +If I execute this, + +00:08:32.320 --> 00:08:34.561 +note that the the result of + +00:08:34.561 --> 00:08:36.719 +executing this expression + +00:08:36.719 --> 00:08:38.447 +is the name of one of the functions + +00:08:38.447 --> 00:08:40.080 +that it defined. + +00:08:40.080 --> 00:08:42.800 +That is this one here. Let me explain + +00:08:42.800 --> 00:08:46.959 +these examples. 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-orggitfile, where + +00:08:51.839 --> 00:08:54.640 +this orggit in the middle of its name + +00:08:54.640 --> 00:08:59.600 +is exactly this first argument to +code-c-d. + +00:08:59.600 --> 00:09:03.120 +The action of running find-orggitfile + +00:09:03.120 --> 00:09:06.399 +on a string like this is that + +00:09:06.399 --> 00:09:09.680 +find-orggitfile 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 code-c-d, + +00:09:17.920 --> 00:09:21.760 +and then it executes find-fline + +00:09:21.760 --> 00:09:25.680 +on the result, which is this one. + +00:09:25.680 --> 00:09:28.320 +find-fline is my variant of find-file + +00:09:28.800 --> 00:09:32.080 +that supports both spec lists. + +00:09:32.080 --> 00:09:36.880 +This function here that I'm + +00:09:36.880 --> 00:09:38.538 +referring to as a button, + +00:09:38.538 --> 00:09:41.200 +it also defines a function called + +00:09:41.200 --> 00:09:44.880 +find-orggitnode here, where the orggit + +00:09:44.880 --> 00:09:46.839 +is the same string as here. + +00:09:46.839 --> 00:09:50.320 +This function opens a node + +00:09:50.320 --> 00:09:54.160 +of an info manual. This one, + +00:09:54.160 --> 00:09:57.310 +this text here opens this node + +00:09:57.310 --> 00:10:00.080 +in the Org manual. + +00:10:00.080 --> 00:10:03.519 +It is equivalent to this text here. + +00:10:03.519 --> 00:10:06.225 +So in the passage from this line + +00:10:06.225 --> 00:10:08.720 +to this line, we prepended + +00:10:08.720 --> 00:10:12.310 +to the node name the name of +the manual here. + +00:10:12.310 --> 00:10:15.040 +find-node is my variant + +00:10:15.040 --> 00:10:18.160 +of this standard Emacs function here, + +00:10:18.160 --> 00:10:20.119 +but find-node also supports + +00:10:20.119 --> 00:10:23.519 +postback lists. + +00:10:23.519 --> 00:10:26.640 +eev also defines some functions that + +00:10:26.640 --> 00:10:28.423 +define shorter hyperlinks to PDFs + +00:10:28.423 --> 00:10:30.800 +and videos. + +00:10:30.800 --> 00:10:32.574 +Remember that this thing here + +00:10:32.574 --> 00:10:34.322 +is a shorter hyperlink + +00:10:34.322 --> 00:10:36.668 +to a file. This thing here + +00:10:36.668 --> 00:10:39.040 +is a shorter hyperlink to a node + +00:10:39.040 --> 00:10:43.200 +in an Emacs menu in an info manual. + +00:10:43.200 --> 00:10:47.279 +If we run this thing here, this +code-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 --> 00:10:56.669 +and this string, +this other sexp here, + +00:10:56.669 --> 00:10:58.430 +defines another function. + +00:10:58.430 --> 00:11:00.240 +The first one defines + +00:11:00.240 --> 00:11:02.745 +the function find-fongspivak-page, + +00:11:02.745 --> 00:11:05.360 +and the second one defines the +function find-fongspivak-text. + +00:11:05.360 --> 00:11:09.608 +When we run the file, + +00:11:09.608 --> 00:11:12.020 +when we run find-fongspivak-page, + +00:11:12.020 --> 00:11:15.686 +it opens this PDF here. + +00:11:15.686 --> 00:11:20.640 +The name is quite long. + +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 --> 00:11:31.279 +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. + +00:11:42.640 --> 00:11:45.200 +Here it is, the contents of a book + +00:11:45.200 --> 00:11:51.760 +that is freely available. Here is +another page of the book. + +00:11:51.760 --> 00:11:55.519 +And if we execute this +hyperlink here, + +00:11:55.519 --> 00:11:58.399 +find-fongspivak-text, it converts the + +00:11:58.399 --> 00:11:59.920 +PDF to text + +00:11:59.920 --> 00:12:03.382 +and it searches for +page eight in it, + +00:12:03.382 --> 00:12:04.754 +and then for the string, + +00:12:04.754 --> 00:12:08.079 +this 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 --> 00:12:20.892 +ASCII version of this contents page +here. + +00:12:20.892 --> 00:12:25.040 +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 --> 00:12:31.360 +I have the full index somewhere, + +00:12:31.360 --> 00:12:32.506 +but it's very long, + +00:12:32.506 --> 00:12:34.959 +so I just copied a few lines here. + +00:12:34.959 --> 00:12:38.959 +So this is a link to s + +00:12:38.959 --> 00:12:42.160 +section one, chapter one. This is the + +00:12:42.160 --> 00:12:48.959 +section 1.1, section 1.1.1, and so on. + +00:12:48.959 --> 00:12:54.000 +Here is a link to the index. + +00:12:54.000 --> 00:12:58.079 +Here is a part of my index + +00:12:58.079 --> 00:13:03.279 +of positions in the video +that we just saw + +00:13:03.279 --> 00:13:07.360 +that I think that are especially +relevant. + +00:13:07.360 --> 00:13:11.940 +So this hyperlink is a kind +of a button + +00:13:11.940 --> 00:13:14.160 +that defines this function here, + +00:13:14.160 --> 00:13:18.839 +find-punchandjudyvideo. Into the video. + +00:13:27.600 --> 00:13:30.800 +We can also use this for + +00:13:30.800 --> 00:13:33.360 +video tutorials. For example, + +00:13:33.360 --> 00:13:37.200 +this is a very good tutorial on Magit. + +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 Magit. + +00:13:48.399 --> 00:13:50.079 +These are some of the positions in the + +00:13:50.079 --> 00:13:52.904 +tutorial that I found +especially relevant. + +00:13:52.904 --> 00:13:54.408 +This is a very dense tutorial. + +00:13:54.408 --> 00:13:56.480 +I had to take notes +of everything, + +00:13:56.480 --> 00:13:59.040 +and I had to watch everything + +00:13:59.040 --> 00:14:00.800 +several times. + +00:14:00.800 --> 00:14:02.896 +For example, this is a link + +00:14:02.896 --> 00:14:05.444 +to the position in the tutorial + +00:14:05.444 --> 00:14:11.005 +that explains how in Spacemacs, + +00:14:11.005 --> 00:14:17.600 +Magit interprets SPC g s as magit-status. + +00:14:17.600 --> 00:14:20.480 +Let's see. "...beginners. +SPC g s to initiate + +00:14:20.480 --> 00:14:22.320 +Magit's git status. + +00:14:22.320 --> 00:14:25.600 +You can also do..." That's it. + +00:14:25.600 --> 00:14:28.800 +Here are some examples that I + +00:14:28.800 --> 00:14:31.200 +took from somewhere else. + +00:14:31.200 --> 00:14:34.240 +The video tutorials from + +00:14:34.240 --> 00:14:43.519 +Rainer Koenig about Org Mode. + +00:14:43.519 --> 00:14:45.308 +Now let me show how the functions + +00:14:45.308 --> 00:14:47.220 +that define these shorter hyperlinks + +00:14:47.220 --> 00:14:48.720 +are implemented. + +00:14:48.720 --> 00:14:50.509 +The standard ways in Emacs + +00:14:50.509 --> 00:14:53.741 +to define functions that define +other functions + +00:14:53.741 --> 00:14:55.760 +would be with macros. + +00:14:55.760 --> 00:14:58.320 +Let's see an example. This is a standard + +00:14:58.320 --> 00:15:01.540 +function that defines new functions. + +00:15:02.959 --> 00:15:06.959 +If we execute it, + +00:15:06.959 --> 00:15:09.040 +its result is the last function that it + +00:15:09.040 --> 00:15:11.527 +defined, which is ee-glyph, + +00:15:11.527 --> 00:15:13.920 +which is here. + +00:15:13.920 --> 00:15:16.959 +It's implemented as a macro. We can + +00:15:16.959 --> 00:15:20.880 +look at the result of macro-expand, +which is going to + +00:15:20.880 --> 00:15:22.975 +show us the result of this, + +00:15:22.975 --> 00:15:25.519 +of the expansion of this. + +00:15:25.519 --> 00:15:27.804 +Instead of expanding and executing, + +00:15:27.804 --> 00:15:33.199 +it just expands and shows us the result. + +00:15:33.199 --> 00:15:35.439 +Here the result is a bit messy. + +00:15:35.439 --> 00:15:39.396 +It's too big for humans to understand, + +00:15:39.396 --> 00:15:42.894 +but we can run this or this text here. + +00:15:42.894 --> 00:15:47.519 +That takes that result +and pretty-prints it. + +00:15:47.519 --> 00:15:50.701 +So this is the pretty-printed version + +00:15:50.701 --> 00:15:54.000 +of 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 --> 00:16:13.839 +to the definition of cl-defstruct. + +00:16:13.839 --> 00:16:16.880 +Note that the code is huge. + +00:16:16.880 --> 00:16:18.677 +Well, it's very well-commented, + +00:16:18.677 --> 00:16:22.577 +but it has lots of special cases. + +00:16:22.577 --> 00:16:26.210 +It supports lots of constructions, + +00:16:26.210 --> 00:16:27.920 +and so it's huge. + +00:16:27.920 --> 00:16:30.174 +It's very difficult to understand. + +00:16:30.174 --> 00:16:33.360 +I mean, I found it very difficult +to understand. + +00:16:33.360 --> 00:16:35.040 +Here's a link to document the + +00:16:35.040 --> 00:16:37.759 +documentation of cl-defstruct + +00:16:37.759 --> 00:16:42.210 +here in the manual for cl, + +00:16:42.210 --> 00:16:45.025 +which is a kind of support + +00:16:45.025 --> 00:16:50.480 +for some features of Common Lisp +in Emacs. + +00:16:50.480 --> 00:16:53.825 +So let's compare this standard way of + +00:16:53.825 --> 00:16:56.560 +defining functions that +define new functions, + +00:16:56.560 --> 00:16:59.253 +which is with macros, +with this. + +00:16:59.253 --> 00:17:02.300 +I'm going to use a slogan +repeatedly. + +00:17:02.300 --> 00:17:06.319 +The slogan is: "I am a very bad +programmer." + +00:17:06.319 --> 00:17:08.005 +I'm a very bad programmer. + +00:17:08.005 --> 00:17:10.082 +So, when I was trying to create +functions + +00:17:10.082 --> 00:17:12.240 +that would 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 --> 00:17:24.640 +The code-c-d that we saw +in the previous section, + +00:17:24.640 --> 00:17:28.079 +we can see the code that it produces + +00:17:28.079 --> 00:17:30.769 +by making a copy of this line + +00:17:30.769 --> 00:17:32.579 +and prepending this string here + +00:17:32.579 --> 00:17:34.480 +to the name of the function. + +00:17:34.480 --> 00:17:36.317 +So, instead of running code-c-d, + +00:17:36.317 --> 00:17:38.400 +we run 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-c-d would execute. + +00:17:47.760 --> 00:17:54.080 +So it's a series of the defuns +and a few setqs and so on. + +00:17:54.080 --> 00:17:59.120 +And this thing is implemented mostly as +a template. + +00:18:02.160 --> 00:18:04.045 +There's an inner function called + +00:18:04.045 --> 00:18:06.240 +ee-code-c-d-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, it just runs the function + +00:18:10.640 --> 00:18:14.320 +ee-template0 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 +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. + +00:18:37.760 --> 00:18:39.679 +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... + +00:18:48.480 --> 00:18:49.662 +So in the beginning, I said + +00:18:49.662 --> 00:18:51.600 +that the three main keys of eev + +00:18:51.600 --> 00:18:56.000 +are M-e, M-k and M-j. + +00:18:56.000 --> 00:19:00.080 +Let's see now what M-j does. + +00:19:00.080 --> 00:19:02.447 +I need to start with some +motivation. + +00:19:02.447 --> 00:19:04.640 +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. 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 defun 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 --> 00:19:20.530 +and I can invoke... You invoke it + +00:19:20.530 --> 00:19:21.856 +with M-x e. + +00:19:21.856 --> 00:19:24.720 +If I type M-x p, + +00:19:24.720 --> 00:19:26.661 +now it opens a LaTeX file + +00:19:26.661 --> 00:19:31.130 +that I'm working on. + +00:19:32.559 --> 00:19:35.200 +I create most of my LaTeX files + +00:19:35.200 --> 00:19:39.200 +using template-based functions like + +00:19:39.200 --> 00:19:43.760 +the implementation of code-c-d above. + +00:19:43.760 --> 00:19:45.576 +These template-based functions + +00:19:45.576 --> 00:19:49.280 +create files with extension .tex + +00:19:49.280 --> 00:19:51.280 +that start with a series of defuns + +00:19:51.280 --> 00:19:53.919 +in comments. For example, + +00:19:53.919 --> 00:19:55.926 +let's look at this example here. + +00:19:55.926 --> 00:19:58.049 +If I execute find-latex-links + +00:19:58.049 --> 00:19:59.440 +with this argument, + +00:19:59.440 --> 00:20:02.525 +it's going to do several things + +00:20:02.525 --> 00:20:08.320 +for creating a file called /tmp/foo.tex, + +00:20:08.320 --> 00:20:10.387 +and the header of that file + +00:20:10.387 --> 00:20:12.400 +is going to be this, + +00:20:12.400 --> 00:20:16.080 +which starts with three + +00:20:16.080 --> 00:20:19.280 +defuns 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, 2020favorite-conventions.tex, + +00:20:32.799 --> 00:20:34.640 +I have this header here in which I + +00:20:34.640 --> 00:20:39.360 +define six functions with +very short 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 +These... We have mnemonics for + +00:20:48.000 --> 00:20:51.520 +these short names here. c is compile, + +00:20:51.520 --> 00:20:54.799 +d is display. I mean, display the PDF. + +00:20:54.799 --> 00:20:57.377 +e is added in the sense of + +00:20:57.377 --> 00:21:02.320 +make Emacs visit that file. + +00:21:02.320 --> 00:21:06.480 +Now I can explain what is M-j +itself. + +00:21:06.480 --> 00:21:09.600 +We just saw commands with +very short names. + +00:21:09.600 --> 00:21:12.048 +The idea behind M-j is that + +00:21:12.048 --> 00:21:14.031 +we can define commands with + +00:21:14.031 --> 00:21:16.480 +very short numbers. + +00:21:16.480 --> 00:21:19.679 +Let me explain this. + +00:21:19.679 --> 00:21:23.039 +The short explanation +for what M-j 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 --> 00:21:30.799 +In particular, a M-j without +a numeric argument + +00:21:30.799 --> 00:21:32.216 +takes us to a buffer + +00:21:32.216 --> 00:21:34.080 +with the basic help + +00:21:34.080 --> 00:21:37.679 +and a list of the current jump targets. + +00:21:37.679 --> 00:21:39.760 +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 M-5 M-j, + +00:21:44.559 --> 00:21:48.411 +then M-j runs this sexp here + +00:21:48.411 --> 00:21:51.120 +that is associated to + +00:21:51.120 --> 00:21:55.440 +the argument 5. I say that the target + +00:21:55.440 --> 00:21:59.039 +for the argument 5 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 true + +00:22:03.760 --> 00:22:07.039 +is this sexp here that opens... + +00:22:07.039 --> 00:22:09.600 +This one opens the main tutorial +for eev, + +00:22:09.600 --> 00:22:13.679 +and this one 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 eev to the part that explains M-j. + +00:22:20.480 --> 00:22:22.212 +I've copied the the main part + +00:22:22.212 --> 00:22:24.559 +of the text here. + +00:22:24.559 --> 00:22:28.159 +The header that M-j shows... + +00:22:28.159 --> 00:22:31.360 +Let me show it very quickly here. + +00:22:31.360 --> 00:22:36.320 +Here is their head and +here is the rest. + +00:22:36.320 --> 00:22:38.773 +The header is very beginner friendly, + +00:22:38.773 --> 00:22:40.000 +and if you're a beginner + +00:22:40.000 --> 00:22:42.159 +who only knows how to use M-e to + +00:22:42.159 --> 00:22:44.559 +execute and... + +00:22:44.559 --> 00:22:46.706 +This should be okay. + +00:22:46.706 --> 00:22:48.240 +M-k to go 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 --> 00:22:58.894 +as your main starting point. + +00:22:58.894 --> 00:23:00.799 +Every time that you feel lost, + +00:23:00.799 --> 00:23:04.799 +you can type M-j to go back to +that header, + +00:23:04.799 --> 00:23:08.000 +and you can use its links to +navigate to the documentation + +00:23:08.000 --> 00:23:11.360 +for Emacs and eev. Let me explain that. + +00:23:11.360 --> 00:23:15.679 +This header here has several elisp +hyperlinks. + +00:23:15.679 --> 00:23:22.400 +One here, one here, one here, +one here, and so on. + +00:23:22.400 --> 00:23:25.760 +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 --> 00:23:31.520 +find-eev-quick-intro is the +main tutorial, + +00:23:31.520 --> 00:23:35.760 +and find-emacs-keys-intro is a +kind of tutorial that is + +00:23:35.760 --> 00:23:40.000 +an index of the main keys. + +00:23:40.000 --> 00:23:42.559 +After that, we have an explanation of + +00:23:42.559 --> 00:23:45.449 +what some numeric prefixes do. + +00:23:45.449 --> 00:23:49.913 +So if we type M-1 M-j, +the effect of that + +00:23:49.913 --> 00:23:53.200 +is exactly the same as +executing this. + +00:23:53.200 --> 00:24:00.159 +We can execute this with M-e also. + +00:24:00.159 --> 00:24:03.679 +M-2 M-j runs this sexp and + +00:24:03.679 --> 00:24:06.960 +I can also execute it with M-e. + +00:24:06.960 --> 00:24:18.400 +Here it is. It's this intro, this +sandbox tutorial. + +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. Then the + +00:24:27.039 --> 00:24:29.388 +documentation says that header, + +00:24:29.388 --> 00:24:31.760 +the header that is beginner-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 --> 00:24:40.400 +that contains a series of defuns +like these ones. + +00:24:40.400 --> 00:24:44.640 +Here, the last line of the header is +this comment here. + +00:24:44.640 --> 00:24:48.559 +Then we have several defuns like this. + +00:24:48.559 --> 00:24:51.440 +Let me explain how these things work. + +00:24:51.440 --> 00:24:53.082 +Technically, what happens + +00:24:53.082 --> 00:24:56.399 +when we type M-j without any arguments + +00:24:56.399 --> 00:25:00.230 +is that it runs eejump with argument nil, + +00:25:00.230 --> 00:25:04.640 +and then this runs 5 eejumps. + +00:25:04.640 --> 00:25:07.224 +When I run M-j with a numeric argument, + +00:25:07.224 --> 00:25:13.374 +for example, with argument 5, +it runs a jump 5. + +00:25:13.374 --> 00:25:17.679 +eejump-5 concatenates this 5 one + +00:25:17.679 --> 00:25:19.999 +to make a name of a function, + +00:25:19.999 --> 00:25:21.679 +this function here. + +00:25:21.679 --> 00:25:24.720 +and it executes this function +eejump-5. + +00:25:24.720 --> 00:25:31.919 +You jump -5, and eejump-5 + +00:25:31.919 --> 00:25:35.520 +executes find-eev-quick-intro. + +00:25:35.520 --> 00:25:39.360 +If I execute just M-j, + +00:25:39.360 --> 00:25:40.533 +the section that shows + +00:25:40.533 --> 00:25:43.919 +the current jump targets + +00:25:43.919 --> 00:25:46.719 +has a line for eejump-5. This is... + +00:25:46.719 --> 00:25:52.400 +That is exactly the thing +that I was explaining before. + +00:25:52.400 --> 00:25:54.544 +So we can use M-j to navigate + +00:25:54.544 --> 00:25:59.520 +the tutorials. We can copy the links. + +00:25:59.520 --> 00:26:03.440 +Sorry. We can copy links to the + +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 eev. + +00:26:20.640 --> 00:26:23.670 +These things are hyperlinks. + +00:26:23.670 --> 00:26:25.597 +I can mark a hyperlink like this. + +00:26:25.597 --> 00:26:27.286 +it is just plain text. + +00:26:27.286 --> 00:26:29.525 +I can copy it to my notes. + +00:26:29.525 --> 00:26:31.760 +The idea is that every time + +00:26:31.760 --> 00:26:34.016 +that I find something that is +interesting, + +00:26:34.016 --> 00:26:36.240 +I can create a hyperlink to it. + +00:26:36.240 --> 00:26:38.513 +I can put these links in my notes + +00:26:38.513 --> 00:26:40.799 +so I can navigate back + +00:26:40.799 --> 00:26:42.667 +to all the interesting positions + +00:26:42.667 --> 00:26:48.799 +very quickly. + +00:26:48.799 --> 00:26:57.600 +Okay, next feature. +If we type M-J (uppercase), then + +00:26:57.600 --> 00:27:00.080 +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 --> 00:27:06.471 +Let me give an example. +Let me isolate this. + +00:27:06.471 --> 00:27:11.039 +Let me duplicate this line +to make clear what happens. + +00:27:11.039 --> 00:27:14.240 +If I type M-J (uppercase) here, + +00:27:14.240 --> 00:27:17.561 +this line here becomes +the defun for eejump-6, + +00:27:17.561 --> 00:27:21.200 +and the target of this eejump + +00:27:21.200 --> 00:27:24.799 +is exactly this sexp here. + +00:27:24.799 --> 00:27:28.559 +Let me undo this mess. + +00:27:28.559 --> 00:27:30.815 +If the first word in the line + +00:27:30.815 --> 00:27:32.840 +is not a number... For example, + +00:27:32.840 --> 00:27:36.240 +here, let me do the same thing: + +00:27:36.240 --> 00:27:41.200 +duplicate the line and type M-J, + +00:27:41.200 --> 00:27:44.014 +then M-J (uppercase) converts that to + +00:27:44.014 --> 00:27:49.440 +a defun that defines a function +with a very short name. + +00:27:49.440 --> 00:27:52.720 +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 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 mess again. + +00:28:05.360 --> 00:28:14.640 +Oops. That's it. + +00:28:14.640 --> 00:28:21.279 +M-J (uppercase) is a particular case +of something that + +00:28:21.279 --> 00:28:23.708 +I use a lot in eev. + +00:28:23.708 --> 00:28:28.799 +eev has lots of commands that-- +sorry, key sequences + +00:28:28.799 --> 00:28:31.466 +that are like M- uppercase letter, + +00:28:31.466 --> 00:28:34.660 +and almost all of them operate + +00:28:34.660 --> 00:28:36.019 +on the current line and + +00:28:36.019 --> 00:28:37.616 +transform the current line + +00:28:37.616 --> 00:28:38.880 +in a certain way. + +00:28:38.880 --> 00:28:42.000 +For example, this is a filename. + +00:28:42.000 --> 00:28:45.360 +If I type M-F (uppercase) here, + +00:28:45.360 --> 00:28:47.967 +it becomes a link to that file. + +00:28:47.967 --> 00:28:50.000 +This is the name of a man page. + +00:28:50.000 --> 00:28:53.600 +If I type M-M (uppercase) here, + +00:28:53.600 --> 00:28:55.292 +it converts that to the link + +00:28:55.292 --> 00:28:58.080 +to a manpage. This is a shell command. + +00:28:58.080 --> 00:29:01.679 +If I type M-S (uppercase) 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-sh (shell). + +00:29:08.720 --> 00:29:12.960 +Until a few years ago, +these functions + +00:29:12.960 --> 00:29:16.159 +with M- uppercase letter were half + +00:29:16.159 --> 00:29:18.880 +of my main ways of creating +sexp hyperlinks + +00:29:18.880 --> 00:29:20.085 +with a few key strokes. + +00:29:20.085 --> 00:29:22.399 +In the beginning, of course, +I had to create my + +00:29:22.399 --> 00:29:25.600 +sexp pipelines by typing each character. + +00:29:25.600 --> 00:29:28.640 +But after some time, I decided that + +00:29:28.640 --> 00:29:31.520 +I needed something more efficient. + +00:29:31.520 --> 00:29:38.480 +So this is the end of part one +of the presentation. + +00:29:38.480 --> 00:29:40.640 +So this is part two of the presentation, + +00:29:40.640 --> 00:29:42.070 +and the main theme here + +00:29:42.070 --> 00:29:44.320 +is the standard describe-key + +00:29:44.320 --> 00:29:46.320 +function that comes with Emacs. + +00:29:46.320 --> 00:29:49.200 +My variant of it... The thing is that + +00:29:49.200 --> 00:29:50.960 +the standard describe-key in Emacs + +00:29:50.960 --> 00:29:52.738 +is user-friendly, but it is + +00:29:52.738 --> 00:29:55.600 +hacker-unfriendly. Well, I felt so. + +00:29:55.600 --> 00:29:58.281 +When I tried to complement it + +00:29:58.281 --> 00:30:00.799 +by writing a hacker-friendly +version of it + +00:30:00.799 --> 00:30:03.919 +that produced the sexp hyperlinks +that I needed, + +00:30:03.919 --> 00:30:06.457 +I got something that +I found really lovely. + +00:30:07.039 --> 00:30:08.994 +Several of the main + +00:30:08.994 --> 00:30:12.480 +design decisions of eev can be seen there. + +00:30:12.480 --> 00:30:13.995 +When I showed my variants to + +00:30:13.995 --> 00:30:15.520 +other people, they hated it. + +00:30:15.520 --> 00:30:16.851 +They felt that it was + +00:30:16.851 --> 00:30:19.360 +totally against their notions of + +00:30:19.360 --> 00:30:23.440 +user-friendliness. + +00:30:23.440 --> 00:30:24.606 +Okay. So let's see. + +00:30:24.606 --> 00:30:26.297 +The standard describe-key, + +00:30:26.297 --> 00:30:30.401 +if I run this hyperlink here, +I get this. + +00:30:30.401 --> 00:30:31.866 +The result of running + +00:30:31.866 --> 00:30:34.399 +describe-key on the key down... + +00:30:34.399 --> 00:30:35.799 +This is a big buffer + +00:30:35.799 --> 00:30:38.080 +with some things in italics. + +00:30:38.080 --> 00:30:40.752 +Some hyperlinks here. + +00:30:40.752 --> 00:30:42.387 +These hyperlinks are standard + +00:30:42.387 --> 00:30:43.679 +in the sense that + +00:30:43.679 --> 00:30:45.407 +the targets are not visible, + +00:30:45.407 --> 00:30:47.760 +and they are implemented using + +00:30:47.760 --> 00:30:49.519 +buttons in Emacs Lisp. + +00:30:49.519 --> 00:30:52.385 +This section of the Emacs Lisp manual + +00:30:52.385 --> 00:30:56.799 +describes how buttons work. + +00:30:56.799 --> 00:31:01.957 +The source code is quite difficult. + +00:31:01.957 --> 00:31:04.240 +I mean, when I was starting to + +00:31:04.240 --> 00:31:05.721 +to try to decipher this + +00:31:05.721 --> 00:31:07.600 +when I was a beginner + +00:31:07.600 --> 00:31:11.200 +using Emacs 19.34, I felt that this + +00:31:11.200 --> 00:31:12.320 +describe-key was + +00:31:12.320 --> 00:31:15.519 +very difficult to understand. + +00:31:15.519 --> 00:31:20.080 +I felt that the the designers, + +00:31:20.080 --> 00:31:22.640 +the people who wrote it, +were sacrificing + +00:31:22.640 --> 00:31:24.839 +too much of the hacker-friendliness + +00:31:24.839 --> 00:31:27.154 +that I was expecting from it + +00:31:27.154 --> 00:31:31.279 +to make it beginner-friendly. + +00:31:31.279 --> 00:31:33.600 +Let me explain. What are the problems + +00:31:33.600 --> 00:31:35.511 +with the standard describe-key? + +00:31:35.511 --> 00:31:37.336 +If we think that hyperlinks + +00:31:37.336 --> 00:31:38.640 +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 --> 00:31:46.516 +these three bad things happen. + +00:31:46.516 --> 00:31:49.983 +First, it is hard to extract +the target from the hyperlink. + +00:31:49.983 --> 00:31:52.000 +Second, it is hard to recreate + +00:31:52.000 --> 00:31:55.440 +a list of code that would +go to that target. + +00:31:55.440 --> 00:31:57.519 +Third, it is hard to copy the full + +00:31:57.519 --> 00:32:00.640 +hyperlink, including the targets +to other buffers. + +00:32:00.640 --> 00:32:04.960 +I only knew how to copy the text + +00:32:04.960 --> 00:32:06.937 +when I was trying to decipher + +00:32:06.937 --> 00:32:09.039 +what describe-key was doing. + +00:32:09.039 --> 00:32:11.679 +I created lots of hyperlinks like this + +00:32:11.679 --> 00:32:16.159 +to inspect the text properties and +things like that. + +00:32:16.159 --> 00:32:18.113 +For example, in the description + +00:32:18.113 --> 00:32:20.390 +of the key down here, + +00:32:20.390 --> 00:32:26.799 +we have a button that points to +simple.el. + +00:32:26.799 --> 00:32:29.336 +The text of that button is simple.el. + +00:32:29.336 --> 00:32:31.600 +This hyperlink goes to the + +00:32:31.600 --> 00:32:35.519 +to the middle of this +button hyperlink here. + +00:32:35.519 --> 00:32:39.120 +This hyperlink here + +00:32:39.120 --> 00:32:43.279 +goes to the middle of the button +of this button hyperlink, + +00:32:43.279 --> 00:32:46.240 +and then inspects its text properties, + +00:32:46.240 --> 00:32:51.679 +and then goes to this section here +of the description. + +00:32:51.679 --> 00:32:53.521 +So this is a high-level description + +00:32:53.521 --> 00:32:56.159 +of the text properties. + +00:32:56.159 --> 00:32:58.782 +I mean, the text properties that make it +a button. + +00:32:58.782 --> 00:33:04.320 +This is a lower-level description of +these text properties. + +00:33:04.320 --> 00:33:08.000 +The button that points to + +00:33:08.000 --> 00:33:11.440 +forward-line--sorry, the button + +00:33:11.440 --> 00:33:14.399 +whose text is forward-line, this one is + +00:33:14.399 --> 00:33:16.480 +slightly different-- + +00:33:16.480 --> 00:33:21.200 +this hyperlink here goes to the middle +of that button. + +00:33:21.200 --> 00:33:25.760 +This hyperlink goes to the middle of +that button, + +00:33:25.760 --> 00:33:28.173 +inspects its text properties, + +00:33:28.173 --> 00:33:29.360 +and goes to the section + +00:33:29.360 --> 00:33:33.617 +of this button of this help buffer here + +00:33:33.617 --> 00:33:36.399 +that describes the button + +00:33:36.399 --> 00:33:41.679 +and the lower-level view of the text +properties. + +00:33:41.679 --> 00:33:45.519 +So I started with things like this + +00:33:45.519 --> 00:33:47.866 +to understand what these buttons +were doing + +00:33:47.866 --> 00:33:49.339 +and I was able to figure out + +00:33:49.339 --> 00:33:51.620 +how these things are implemented + +00:33:51.620 --> 00:33:53.120 +in describe-key, and then + +00:33:53.120 --> 00:33:55.519 +similar help functions in Emacs. + +00:33:55.519 --> 00:33:57.506 +I discovered that one of the + +00:33:57.506 --> 00:33:59.049 +main lower-level functions + +00:33:59.049 --> 00:34:01.360 +that Emacs used for this + +00:34:01.360 --> 00:34:05.279 +is a function called +find-function-noselect. + +00:34:05.279 --> 00:34:09.929 +If I run find-function-noselect +on next line, + +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 + +00:34:21.679 --> 00:34:24.320 +follow this. That would open that + +00:34:24.320 --> 00:34:26.510 +buffer in that position + +00:34:26.510 --> 00:34:29.679 +and then this is a 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 --> 00:34:41.040 +So this goes to the definition +of find-efunction + +00:34:41.040 --> 00:34:45.006 +and then to a string after it. + +00:34:45.006 --> 00:34:48.296 +I use these things to implement + +00:34:48.296 --> 00:34:51.839 +my own functions that pointed to the + +00:34:51.839 --> 00:34:55.339 +same targets as the button hyperlinks + +00:34:55.339 --> 00:35:00.240 +and describe-key. + +00:35:00.240 --> 00:35:02.673 +Again, let me show the comparison. + +00:35:02.673 --> 00:35:06.322 +This is the standard +describe-key here, + +00:35:06.322 --> 00:35:10.480 +and this is my variant. + +00:35:10.480 --> 00:35:13.839 +It creates a buffer with links, + +00:35:13.839 --> 00:35:17.680 +with the list of 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 an elisp hyperlink. + +00:35:28.720 --> 00:35:34.506 +Here is a slight variant of the +function find-ekey-links above. + +00:35:34.506 --> 00:35:39.280 +In this variant, the argument is a +string that has to be processed by + +00:35:39.280 --> 00:35:42.400 +read-kbd-macro to convert it to the + +00:35:42.400 --> 00:35:45.280 +lower-level format. + +00:35:45.280 --> 00:35:49.040 +Note that these functions here +that I wrote, + +00:35:49.040 --> 00:35:50.934 +they display temporary buffers + +00:35:50.934 --> 00:35:53.599 +with no help at all. + +00:35:53.599 --> 00:35:57.131 +To be honest, there's a link to + +00:35:57.131 --> 00:35:58.345 +a tutorial here, + +00:35:58.345 --> 00:36:00.467 +but this is a recent edition + +00:36:00.467 --> 00:36:03.200 +so let's ignore this. + +00:36:03.200 --> 00:36:06.640 +They display temporary buffers + +00:36:06.640 --> 00:36:07.949 +with no help at all, + +00:36:07.949 --> 00:36:09.520 +just lots of hyperlinks. + +00:36:09.520 --> 00:36:11.172 +And these hyperlinks can be... + +00:36:11.172 --> 00:36:13.359 +They are very hacker-friendly +in the sense that + +00:36:13.359 --> 00:36:15.477 +they can be followed with M-e. + +00:36:15.477 --> 00:36:17.520 +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 sexp. + +00:36:23.680 --> 00:36:28.000 +And they can be inspected +in the sense that... + +00:36:28.000 --> 00:36:32.400 +For example, here, + +00:36:32.400 --> 00:36:35.520 +we have a hyperlink to a function +that 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 --> 00:36:41.600 +but we can go to that position, + +00:36:41.600 --> 00:36:45.839 +and then type C-h f to see the + +00:36:45.839 --> 00:36:48.240 +description of this function. + +00:36:48.240 --> 00:36:53.890 +And here is a hyperlink that does that + +00:36:56.000 --> 00:37:00.160 +in my syntax, say. + +00:37:00.160 --> 00:37:02.800 +This list of hyperlinks were + +00:37:02.800 --> 00:37:08.000 +generated by this code here that just + +00:37:08.000 --> 00:37:11.119 +used a back quote to generate + +00:37:11.119 --> 00:37:14.640 +lists of sexps. + +00:37:14.640 --> 00:37:18.240 +I felt that this function here + +00:37:18.240 --> 00:37:20.700 +that just generated this list + +00:37:20.700 --> 00:37:23.393 +was very easy to understand +and to modify, + +00:37:23.393 --> 00:37:28.480 +so this was hacker-friendly +in the way that I wanted. + +00:37:28.480 --> 00:37:31.599 +So I started using this, + +00:37:31.599 --> 00:37:33.459 +and this idea of using buffers + +00:37:33.459 --> 00:37:36.066 +with sexp hyperlinks and no help + +00:37:36.066 --> 00:37:38.720 +violated all the notions +of user-friendliness + +00:37:38.720 --> 00:37:40.079 +that I knew, so I was + +00:37:40.079 --> 00:37:41.504 +exploring something new + +00:37:41.504 --> 00:37:46.160 +at that time. This is the end of +part two. + +00:37:46.160 --> 00:37:49.359 +Part three of this presentation is + +00:37:49.359 --> 00:37:51.735 +about the killer features of eev, + +00:37:51.735 --> 00:37:53.778 +or why everybody should use eev + +00:37:53.778 --> 00:37:55.789 +or at least have eev installed + +00:37:55.789 --> 00:37:59.280 +even if they think that eev +is too weird. + +00:37:59.280 --> 00:38:01.200 +So this is a very quick listing. + +00:38:01.200 --> 00:38:04.240 +eev has elisp hyperlinks +which are super nice. + +00:38:04.240 --> 00:38:06.050 +It comes with lots of tutorials. + +00:38:06.050 --> 00:38:10.800 +The main one here explains all the +main features. + +00:38:10.800 --> 00:38:14.079 +There's also a tutorial that's + +00:38:14.079 --> 00:38:18.079 +an index of all the other tutorials here. + +00:38:18.079 --> 00:38:20.509 +Many, many, many tutorials. + +00:38:20.509 --> 00:38:24.079 +If we forget everything, +we can just type M-j. + +00:38:24.079 --> 00:38:28.104 +Remember that this part here +is beginner-friendly, + +00:38:28.104 --> 00:38:32.960 +and the rest is +beginner-unfriendly. + +00:38:32.960 --> 00:38:38.320 +There's a tutorial on Emacs Lisp here. + +00:38:38.320 --> 00:38:41.920 +It mainly explains how to understand + +00:38:41.920 --> 00:38:44.640 +Elisp code, which is much easier than... + +00:38:44.640 --> 00:38:46.673 +It's much easier to understand +Elisp code + +00:38:46.673 --> 00:38:50.160 +than to understand how to +program in Elisp. + +00:38:50.160 --> 00:38:53.440 +Most people are only going to need this. + +00:38:53.440 --> 00:38:55.368 +eev is very easy to install. + +00:38:55.368 --> 00:38:58.240 +It's in ELPA, so we just need to do + +00:38:58.240 --> 00:39:03.520 +this thing here, and it's very +non-invasive. + +00:39:03.520 --> 00:39:05.472 +Years ago, several years ago, + +00:39:05.472 --> 00:39:07.039 +it was a very invasive package, + +00:39:07.039 --> 00:39:08.960 +but then I changed everything. + +00:39:08.960 --> 00:39:13.520 +Now, if we toggle eev-mode on and off, + +00:39:13.520 --> 00:39:16.320 +what's going to happen is just that + +00:39:16.320 --> 00:39:21.599 +the eev-keymap becomes activated or +deactivated. + +00:39:21.599 --> 00:39:24.720 +When we install eev-- + +00:39:24.720 --> 00:39:27.064 +I mean when we require eev, + +00:39:27.064 --> 00:39:32.640 +the only things that happens globally +are these things here: + +00:39:32.640 --> 00:39:34.993 +several functions and variables +become defined. + +00:39:34.993 --> 00:39:40.079 +All of them have 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 --> 00:39:52.780 +the red star, the open +double angle brackets, + +00:39:52.780 --> 00:39:58.160 +and the closed double angle brackets. + +00:39:58.160 --> 00:40:01.359 +Two environment variables are set. + +00:40:01.359 --> 00:40:04.560 +This is a trivial technicality. + +00:40:04.560 --> 00:40:10.800 +We just run a defadvice around one +function that is used by "man." + +00:40:10.800 --> 00:40:18.400 +Also, eev has a very high +discoverability factor. + +00:40:18.400 --> 00:40:22.135 +There's a way to create, +a very easy way + +00:40:22.135 --> 00:40:25.200 +to create a hyperlink to here. + +00:40:25.200 --> 00:40:27.760 +I do not have time to show this now, + +00:40:27.760 --> 00:40:31.200 +but for example, if I'm here +in a tutorial, + +00:40:31.200 --> 00:40:35.736 +and I think that this section +is something interesting + +00:40:35.736 --> 00:40:39.520 +and I want to create a hyperlink to it, + +00:40:39.520 --> 00:40:43.040 +I just have to type a certain key +sequence here, + +00:40:43.040 --> 00:40:45.783 +and here I got a hyperlink + +00:40:45.783 --> 00:40:48.269 +that I can copy to my notes, + +00:40:48.269 --> 00:40:52.260 +and this hyperlink goes to that section. + +00:40:58.240 --> 00:41:02.092 +We have hyperlinks that point to +specific positions + +00:41:02.092 --> 00:41:05.382 +in PDF documents and in video files. + +00:41:05.382 --> 00:41:09.119 +Here, this one opens a PDF +and displays it. + +00:41:09.119 --> 00:41:13.920 +This one opens a PDF +and converts it to text. + +00:41:13.920 --> 00:41:18.400 +and this one opens the video in a +certain position. + +00:41:18.400 --> 00:41:20.480 +We also have a way to control + +00:41:20.480 --> 00:41:22.079 +shell-like programs. + +00:41:22.079 --> 00:41:25.111 +In my presentation of the last year, + +00:41:25.111 --> 00:41:28.163 +I spent one third of the presentation +explaining this, + +00:41:28.163 --> 00:41:31.839 +and I think that I gave a very good +demonstration there. + +00:41:31.839 --> 00:41:35.680 +The demonstration is here. + +00:41:35.680 --> 00:41:37.908 +We can go to the web page, + +00:41:37.908 --> 00:41:41.839 +go to this section of the web page, + +00:41:41.839 --> 00:41:47.680 +and start by this point. + +00:41:47.680 --> 00:41:55.920 +And here we have an explanation +and so on. Whatever. + +00:41:55.920 --> 00:41:58.720 +I've already mentioned this before. + +00:41:59.200 --> 00:42:02.240 +eev comes with a very nice Elisp +tutorial. + +00:42:02.240 --> 00:42:05.599 +So that's it. This is the end of part +three. + +00:42:05.599 --> 00:42:08.103 +So this is the last part of my +presentation, + +00:42:08.103 --> 00:42:10.965 +and it's about the title of the +presentation. + +00:42:10.965 --> 00:42:13.599 +I called the presentation, "Why + +00:42:13.599 --> 00:42:16.560 +Most of the Best Features in eev Look + +00:42:16.560 --> 00:42:20.480 +Like Five-Minute Hacks." I've already + +00:42:20.480 --> 00:42:23.920 +run out of time, so I have to skip this + +00:42:23.920 --> 00:42:28.485 +first part here in which +I describe how + +00:42:28.485 --> 00:42:33.440 +I was exposed to several different +notions of user-friendliness, + +00:42:33.440 --> 00:42:35.920 +and how the one that really blew my mind + +00:42:35.920 --> 00:42:41.680 +was the one in a certain +Forth environment. + +00:42:41.680 --> 00:42:44.160 +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 +In all this process, I switched from + +00:42:49.680 --> 00:42:52.960 +the belief that the user was always +someone else, + +00:42:52.960 --> 00:42:55.359 +someone external, and 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 --> 00:43:00.173 +from that to the belief + +00:43:00.173 --> 00:43:03.200 +that I am the user. + +00:43:03.200 --> 00:43:06.319 +I can play with the interface +that I want. + +00:43:06.319 --> 00:43:10.079 +I can write programs + +00:43:10.079 --> 00:43:11.786 +that only I am going to understand. + +00:43:11.786 --> 00:43:14.240 +I can experiment with +hundreds of interfaces, + +00:43:14.240 --> 00:43:16.079 +select the best ones, + +00:43:16.079 --> 00:43:18.720 +document them, and then share them + +00:43:18.720 --> 00:43:20.960 +with other people + +00:43:20.960 --> 00:43:24.056 +who are also experimenting +with interfaces + +00:43:24.056 --> 00:43:27.050 +in their own ways. + +00:43:27.050 --> 00:43:30.879 +So eev has lots of things +that are user-friendly + +00:43:30.879 --> 00:43:34.880 +in these unusual ways that I've +explained before. + +00:43:34.880 --> 00:43:37.160 +If we consider that + +00:43:37.160 --> 00:43:40.319 +this notion of user-friendliness +is valid, + +00:43:40.319 --> 00:43:44.651 +then these things that eev implements, + +00:43:44.651 --> 00:43:46.904 +they are user-friendly +and hacker-friendly + +00:43:46.904 --> 00:43:48.800 +at the same time. + +00:43:48.800 --> 00:43:50.346 +Let me show one example. + +00:43:51.119 --> 00:43:56.640 +This is one that really took me only +five minutes to implement. + +00:43:56.640 --> 00:43:59.430 +At one point a few months ago, + +00:43:59.430 --> 00:44:05.599 +I discovered that Sacha Chua's weekly +posts about Emacs News + +00:44:05.599 --> 00:44:08.800 +were also being posted to a + +00:44:08.800 --> 00:44:12.893 +mailing list that is stored at +lists.gnu.org, + +00:44:12.893 --> 00:44:16.319 +and it's called emacs-tangents. + +00:44:16.319 --> 00:44:19.760 +I found a way to create + +00:44:19.760 --> 00:44:25.440 +the links to the posts in both places, + +00:44:25.440 --> 00:44:28.178 +but I had to use a template for that. + +00:44:28.178 --> 00:44:30.640 +So what we are seeing here now + +00:44:30.640 --> 00:44:33.221 +is a template with +the default values. + +00:44:33.221 --> 00:44:38.243 +So this means that we have not set the +year correctly. + +00:44:38.243 --> 00:44:40.720 +We have not set the month correctly, + +00:44:40.720 --> 00:44:42.173 +or the day correctly, + +00:44:42.173 --> 00:44:45.462 +but if we run this sexp here... + +00:44:45.462 --> 00:44:48.960 +Let me do something else before... + +00:44:48.960 --> 00:44:53.359 +If we run this sexp here, + +00:44:53.359 --> 00:45:00.880 +we change some of these entries + +00:45:00.880 --> 00:45:05.200 +in the template, and we get +these links here. + +00:45:05.200 --> 00:45:07.719 +They all work. For example, + +00:45:07.719 --> 00:45:13.552 +this one opens the blog post in +Sacha Chua's site, + +00:45:13.552 --> 00:45:21.280 +and this one opens it +in the mailing list. + +00:45:21.280 --> 00:45:23.672 +Sometimes I want +the Org source of that, + +00:45:23.672 --> 00:45:26.520 +and the easiest way +to get the Org source + +00:45:26.520 --> 00:45:31.680 +is to look at this link here +that has an attachment. + +00:45:31.680 --> 00:45:35.839 +If I take this link here, + +00:45:35.839 --> 00:45:43.342 +and I take this stem that points to the +attachment, and I put it here, + +00:45:43.342 --> 00:45:45.440 +and I generate this page again + +00:45:45.440 --> 00:45:50.000 +with all this data, +then I get a script here + +00:45:50.000 --> 00:45:51.673 +that downloads... + +00:45:51.673 --> 00:45:54.640 +Let me switch to a smaller font. + +00:45:54.640 --> 00:45:58.160 +It downloads this attachment + +00:45:58.160 --> 00:46:01.599 +and it renames that attachment to +something: + +00:46:01.599 --> 00:46:06.000 +./emacs-news -- sorry, something's... + +00:46:06.000 --> 00:46:10.720 +-emacs-news-something + +00:46:10.720 --> 00:46:15.119 +something emacs-news.org here. + +00:46:15.119 --> 00:46:16.750 +The file is already here, + +00:46:16.750 --> 00:46:18.400 +already with the right name. + +00:46:18.400 --> 00:46:22.079 +So I can open it with +just this hyperlink. + +00:46:22.079 --> 00:46:23.780 +Let me go to the big font again. + +00:46:25.200 --> 00:46:28.673 +And now I have the Org source +for that hyperlink-- + +00:46:28.673 --> 00:46:33.839 +Sorry, for that blog post. + +00:46:33.839 --> 00:46:37.911 +And so this one-line thing here + +00:46:37.911 --> 00:46:40.960 +is, in a sense, + +00:46:40.960 --> 00:46:45.119 +a hyperlink to this blog post +in all its formats. + +00:46:45.119 --> 00:46:48.640 +If I execute this, I get links to + +00:46:48.640 --> 00:46:52.000 +all the places where it is posted, + +00:46:52.000 --> 00:46:56.000 +and I get a script to +download the local copy + +00:46:56.000 --> 00:47:00.480 +of the Org source of it.

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

Should you +do it this way or that way? + +00:00:37.200 --> 00:00:39.931 +I thought maybe I should try a different way. + +00:00:39.931 --> 00:00:42.567 +But I'm talking about special blocks + +00:00:42.567 --> 00:00:45.039 +and if I show you an Emacs, then I have to export + +00:00:45.039 --> 00:00:47.840 +the HTML so you can see what it looks like + +00:00:47.840 --> 00:00:51.920 +or export to a PDF so you can see what it looks like. + +00:00:51.920 --> 00:00:54.239 +So I ended up writing in org-reveal, + +00:00:54.239 --> 00:00:58.233 +and joyously, this just works. + +00:00:58.960 --> 00:01:00.879 +You can just see things here. + +00:01:00.879 --> 00:01:03.452 +I was worried that I'd have to take pictures + +00:01:03.452 --> 00:01:09.760 +and then insert pings, so that was a delight. + +00:01:09.760 --> 00:01:15.704 +Okay. Special blocks are these things like a center small quote. + +00:01:15.704 --> 00:01:17.280 +That's what a special block is, + +00:01:17.280 --> 00:01:19.733 +and with a bit of Lisp, we can make + +00:01:19.733 --> 00:01:22.741 +special blocks and link types. + +00:01:22.741 --> 00:01:24.799 +Right. Using a single interface. + +00:01:24.799 --> 00:01:27.344 +The interface is going to be similar + +00:01:27.344 --> 00:01:29.281 +to one many people are familiar with. + +00:01:29.281 --> 00:01:34.712 +In particular, Org Babel's src interface + +00:01:34.712 --> 00:01:37.840 +as well as using global header arguments for link types. + +00:01:37.840 --> 00:01:39.450 +The idea is to write it once + +00:01:39.450 --> 00:01:41.200 +and generate many different kinds. + +00:01:41.200 --> 00:01:45.213 +You write in Org markup and you can have HTML, + +00:01:45.213 --> 00:01:49.767 +you can have PDF, and joyously, org-reveal. + +00:01:49.767 --> 00:01:53.600 +That was an unexpected delight. + +00:01:53.600 --> 00:01:57.840 +Here are a few that you'll just see + +00:01:57.840 --> 00:02:01.759 +in this presentation. + +00:02:01.759 --> 00:02:05.040 +I won't show some of these link-only ones, + +00:02:05.040 --> 00:02:06.799 +but we'll see a few of these other ones + +00:02:06.799 --> 00:02:09.500 +just to make the presentation look nice + +00:02:09.500 --> 00:02:11.520 +So the presentation is really going to + +00:02:11.520 --> 00:02:14.000 +present these blocks and the mechanism + +00:02:14.000 --> 00:02:15.120 +at the same time. + +00:02:15.120 --> 00:02:18.400 +No HTML was written. + +00:02:18.400 --> 00:02:21.280 +Look, Ma! No HTML, just pure Org Mode, + +00:02:21.280 --> 00:02:25.840 +and you get all these beautiful boxes and things. + +00:02:25.840 --> 00:02:27.680 +The motivation for this is... + +00:02:29.120 --> 00:02:31.200 +you're online, you run into a blog, + +00:02:31.200 --> 00:02:32.120 +and you see something you like, + +00:02:32.120 --> 00:02:33.120 +and you're like, man, + +00:02:33.120 --> 00:02:36.640 +you know, I wish I could produce that. + +00:02:36.640 --> 00:02:41.639 +But you check, and the author wrote raw HTML. + +00:02:41.639 --> 00:02:44.239 +You know, #+HTML: everywhere. + +00:02:44.239 --> 00:02:49.533 +That's going to obscure your real content. + +00:02:49.533 --> 00:02:51.200 +It's going to be surrounded by all this + +00:02:51.200 --> 00:02:54.239 +styling information. That's unfortunate. + +00:02:54.239 --> 00:02:57.033 +The author decides to use an Org macro. + +00:02:57.033 --> 00:02:58.959 +All right, a bit better, + +00:02:58.959 --> 00:03:00.333 +but then what if you decide, + +00:03:00.333 --> 00:03:04.667 +hey I want to make a PDF? Not great. + +00:03:04.667 --> 00:03:06.000 +And then the worst of all, + +00:03:06.000 --> 00:03:07.840 +the author doesn't give you the source, + +00:03:07.840 --> 00:03:10.159 +and then you have to view page source, + +00:03:10.159 --> 00:03:13.760 +and learn cascading style sheets, + +00:03:14.239 --> 00:03:15.767 +and sit in a corner and cry, + +00:03:15.767 --> 00:03:18.080 +and decide to do other things with your life. + +00:03:18.080 --> 00:03:22.640 +We want to give you Org users numerous styles + +00:03:22.640 --> 00:03:27.200 +and an extensible mechanism to add more of these + +00:03:27.200 --> 00:03:28.799 +aesthetically pleasing styles, + +00:03:28.799 --> 00:03:31.200 +to have really nice things + +00:03:31.200 --> 00:03:33.933 +look one way in the HTML + +00:03:33.933 --> 00:03:36.567 +and look almost the same way in the PDF + +00:03:36.567 --> 00:03:38.667 +and other back ends. + +00:03:38.667 --> 00:03:41.680 +And if by having these newer ones, + +00:03:41.680 --> 00:03:45.519 +people might be encouraged to try making new ones, + +00:03:45.519 --> 00:03:49.040 +especially when the interface is not so difficult, + +00:03:49.040 --> 00:03:54.159 +that's the aim. + +00:03:54.159 --> 00:03:59.120 +So let's have a real story to motivate this even more. + +00:03:59.120 --> 00:04:03.533 +Here's three friends. I hope I don't butcher their names, + +00:04:03.533 --> 00:04:04.640 +but these friends are called + +00:04:04.640 --> 00:04:08.720 +Amin, Sacha, and Corwin. They're organizing a conference, + +00:04:08.720 --> 00:04:12.080 +EmacsConf 2020. + +00:04:12.080 --> 00:04:14.239 +So Sacha decides to write an Org file + +00:04:14.239 --> 00:04:16.479 +and she would like some feedback. + +00:04:16.479 --> 00:04:19.840 +Okay. Just to make it clear, there's no... + +00:04:19.840 --> 00:04:22.960 +just how easy this looks, + +00:04:22.960 --> 00:04:27.280 +let's look at the source for this block. + +00:04:27.280 --> 00:04:30.720 +Notice it's just the word "green," then a colon, + +00:04:30.720 --> 00:04:37.333 +then Amin. No div style coloring, + +00:04:37.333 --> 00:04:38.479 +just green:Amin. + +00:04:38.479 --> 00:04:41.520 +A very pleasant Org markup. + +00:04:41.520 --> 00:04:44.960 +So that's quite nice. Put some bold around it. + +00:04:44.960 --> 00:04:46.433 +Not too difficult. + +00:04:46.433 --> 00:04:49.900 +Hopefully, this will be useful to other people as well. + +00:04:49.900 --> 00:04:52.240 +So what kind of feedback + +00:04:52.240 --> 00:04:55.233 +would Sacha expect to get? + +00:04:55.233 --> 00:04:59.120 +Maybe she would expect top-level remarks + +00:04:59.120 --> 00:05:00.833 +visible in the export. + +00:05:00.833 --> 00:05:04.400 +When she makes an HTML, she can see right there a big block. + +00:05:04.400 --> 00:05:09.533 +Right. Maybe Amin will suggest to Sacha, + +00:05:09.533 --> 00:05:11.120 +please replace this part + +00:05:11.120 --> 00:05:12.267 +with this other part + +00:05:12.267 --> 00:05:13.333 +or replace this word + +00:05:13.333 --> 00:05:14.639 +with this other word. + +00:05:14.639 --> 00:05:16.960 +This is not really possible + +00:05:16.960 --> 00:05:21.919 +with raw HTML or with even LaTeX. + +00:05:21.919 --> 00:05:24.000 +You'd have to have multiple arguments: + +00:05:24.000 --> 00:05:25.360 +the first argument, and then + +00:05:25.360 --> 00:05:28.800 +the replacement argument. It's a bit clunky. + +00:05:28.800 --> 00:05:32.080 +But with our setup, you just write some text, + +00:05:32.080 --> 00:05:34.367 +write #+replace_with + +00:05:34.367 --> 00:05:36.240 +and then write more text, and you're good to go. + +00:05:36.240 --> 00:05:39.440 +Normal Org markup. + +00:05:39.440 --> 00:05:40.720 +Everyone speaks different languages. + +00:05:40.720 --> 00:05:43.833 +Maybe they want to use one word, + +00:05:43.833 --> 00:05:45.919 +or they're arguing about + +00:05:45.919 --> 00:05:48.000 +whether we talk about frames or windows, + +00:05:48.000 --> 00:05:50.560 +so maybe they want to have some translations. + +00:05:50.560 --> 00:05:53.433 +So there are different kinds of feedback. + +00:05:53.433 --> 00:05:55.360 +Let's take an example. + +00:05:55.360 --> 00:05:59.360 +Look at what they are. + +00:05:59.360 --> 00:06:02.560 +For example, Sacha might write + +00:06:02.560 --> 00:06:06.160 +this Org Mode right here, + +00:06:06.160 --> 00:06:09.759 +and then in her HTML exports, you might see this, + +00:06:09.759 --> 00:06:12.733 +and her feedback might look really nicely + +00:06:12.733 --> 00:06:13.840 +from anyone who says + +00:06:14.560 --> 00:06:17.400 +let's do some Lisp instead of mathematics. + +00:06:17.400 --> 00:06:18.560 +Let's just do some Lisp. + +00:06:18.560 --> 00:06:22.479 +Corwin says, let's not be so silly. + +00:06:22.479 --> 00:06:25.120 +Let's just say 9 a.m. and move on. + +00:06:28.080 --> 00:06:31.360 +Amin likes to export to PDF, + +00:06:31.360 --> 00:06:34.333 +and so he writes his top-level remarks using LaTeX. + +00:06:34.333 --> 00:06:36.900 +That's how. To get this square + +00:06:36.900 --> 00:06:38.960 +Amin: please change whatever, + +00:06:38.960 --> 00:06:43.120 +he might write like this: #+latex:. + +00:06:43.120 --> 00:06:50.880 +But then Sacha only exports to HTML, for example, + +00:06:50.880 --> 00:06:54.880 +so she doesn't look at the PDF, + +00:06:54.880 --> 00:06:57.867 +and she may not see his top-level feedback + +00:06:57.867 --> 00:07:00.667 +with those nice brackets and and bold. + +00:07:00.667 --> 00:07:03.120 +She might think everything's good. + +00:07:03.120 --> 00:07:06.160 +That can be a bit disastrous. + +00:07:06.160 --> 00:07:08.600 +So maybe Sacha will then + +00:07:08.600 --> 00:07:13.199 +make some of her own feedback. + +00:07:13.199 --> 00:07:16.160 +To produce it, she might write + +00:07:16.560 --> 00:07:21.680 +HTML commands, #+html: to get that. + +00:07:21.680 --> 00:07:24.100 +But then Amin will make a PDF, + +00:07:24.100 --> 00:07:25.680 +and this won't stick out. + +00:07:25.680 --> 00:07:28.367 +So he might think everything's okay, + +00:07:28.367 --> 00:07:30.160 +even though it's not. + +00:07:30.160 --> 00:07:33.100 +Then Corwin actually decides, + +00:07:33.100 --> 00:07:35.900 +"Hey, let me read the exported result + +00:07:35.900 --> 00:07:38.867 +and there's all those feedback +from two people + +00:07:38.867 --> 00:07:42.633 +who haven't read anything, +because maybe they were in a rush, + +00:07:42.633 --> 00:07:45.167 +and didn't see the top-level feedback. + +00:07:45.167 --> 00:07:50.000 +So they agree. "Hey, let's have a +uniform Org interface that exports + +00:07:50.000 --> 00:07:52.567 +to both HTML and PDF. + +00:07:52.567 --> 00:07:54.080 +Make both of us happy." + +00:07:54.080 --> 00:07:58.160 +Okay. So they decide to use +Org special blocks. + +00:07:58.160 --> 00:08:01.300 +Right. To set this up, + +00:08:01.300 --> 00:08:04.400 +they need to read a little bit of Lisp, + +00:08:04.400 --> 00:08:08.879 +hooks, advice, macros to get all of this +set up, + +00:08:08.879 --> 00:08:12.319 +and then they'll use Org as the main +interface. + +00:08:12.319 --> 00:08:16.479 +It's a lot of work, but it's worth it, +right? maybe? + +00:08:16.479 --> 00:08:19.360 +But then Corwin's a bit terse. + +00:08:19.759 --> 00:08:24.333 +Corwin maybe doesn't want to +write using blocks. + +00:08:24.333 --> 00:08:26.080 +He thinks they're overkill. + +00:08:26.080 --> 00:08:32.560 +Sacha wants HTML, and Amin wants PDF, +and Corwin wants org-reveal. + +00:08:32.560 --> 00:08:35.533 +So now they have to reformat +all their code. + +00:08:35.533 --> 00:08:36.900 +And then they need to use org link types + +00:08:36.900 --> 00:08:38.867 +to reduce the overkill, + +00:08:38.867 --> 00:08:41.367 +so they can try to avoid duplication + +00:08:41.367 --> 00:08:46.800 +by factoring things out into +self-contained functions. + +00:08:46.800 --> 00:08:50.320 +But now, to set up our links, + +00:08:50.320 --> 00:08:55.467 +we'll have to learn a new interface, org +setup link. + +00:08:55.467 --> 00:09:02.160 +Learn a little bit about fonts, follow +links, export handlers... + +00:09:02.160 --> 00:09:05.040 +It's so much. That's so much. But then, + +00:09:05.040 --> 00:09:06.800 +the friends, they learn a lot. + +00:09:06.800 --> 00:09:08.399 +They learn about defun. + +00:09:08.399 --> 00:09:11.120 +So these words are red. + +00:09:11.120 --> 00:09:12.185 +You get a little explanation. + +00:09:12.185 --> 00:09:14.320 +I think it's a bit too small for anyone +to read. + +00:09:14.320 --> 00:09:18.000 +This is Lisp documentation for defun. + +00:09:18.000 --> 00:09:21.600 +advice-add. There's some Lisp +documentation. + +00:09:21.600 --> 00:09:23.600 +They learn about destructuring -let. + +00:09:23.600 --> 00:09:25.279 +This is from the dash library. + +00:09:25.279 --> 00:09:26.959 +Here's all that glorious, + +00:09:26.959 --> 00:09:28.800 +glorious documentation with examples. + +00:09:28.800 --> 00:09:30.300 +Sorry. I like that. + +00:09:30.300 --> 00:09:32.467 +They might make +an ad-hoc mechanism + +00:09:32.467 --> 00:09:35.400 +to simulate arguments for special blocks, + +00:09:35.400 --> 00:09:38.500 +so something maybe called +extract-arguments, + +00:09:38.500 --> 00:09:41.533 +and then, of course, to make +new link types, + +00:09:41.533 --> 00:09:42.480 +they have to learn about + +00:09:42.480 --> 00:09:47.400 +org-link-set-parameters and +its numerous bits and pieces. + +00:09:49.920 --> 00:09:53.600 +Let's close all these ones down. + +00:09:53.600 --> 00:09:55.800 +Of course they also need to be +comfortable + +00:09:55.800 --> 00:09:59.920 +with loops and maps and matching and +string functions. + +00:09:59.920 --> 00:10:02.560 +So it's a bit of a pain. + +00:10:03.360 --> 00:10:05.839 +It's probably not worth it. + +00:10:05.839 --> 00:10:07.767 +Maybe I'll just rush things quickly, + +00:10:07.767 --> 00:10:09.360 +or do it ad-hoc... + +00:10:10.320 --> 00:10:13.680 +We have things to do. + +00:10:13.680 --> 00:10:19.367 +But maybe the squad wants to have a +modular and unified interface + +00:10:19.367 --> 00:10:23.700 +so everyone's comfortable with defun to +define a function + +00:10:23.700 --> 00:10:29.440 +and they say, "It would be nice if we +could just define simultaneously + +00:10:29.440 --> 00:10:32.959 +both a block and the link type." + +00:10:32.959 --> 00:10:36.000 +That way, we have a single interface + +00:10:36.000 --> 00:10:37.867 +Org mode, for these things. + +00:10:37.867 --> 00:10:39.767 +It would be nice if it was modular. + +00:10:39.767 --> 00:10:44.633 +If I defined a one kind of block and +you defined another, + +00:10:44.633 --> 00:10:45.519 +we could compose them, + +00:10:45.519 --> 00:10:49.360 +then get a nice bigger block, like LEGO. + +00:10:49.360 --> 00:10:52.320 +That would be nice. Building blocks. + +00:10:52.320 --> 00:10:56.240 +This is what we have come up with, +called defblock. + +00:10:56.240 --> 00:11:01.760 +It also has a long documentation string +containing examples and things. + +00:11:01.760 --> 00:11:04.800 +So that way, it can try to be useful. + +00:11:04.800 --> 00:11:10.880 +Let's look at a solution to these +friends' trilemma. + +00:11:10.880 --> 00:11:14.320 +So here's a way to define a block. + +00:11:14.320 --> 00:11:22.320 +It doesn't look that difficult, but this +is how they can define a block + +00:11:22.320 --> 00:11:25.920 +for their top-level feedback. + +00:11:25.920 --> 00:11:28.959 +Let's look at the three main parts +together. + +00:11:28.959 --> 00:11:31.233 +It's not that difficult, I hope. + +00:11:31.233 --> 00:11:35.300 +Just six lines, and that's including a +documentation string, + +00:11:35.300 --> 00:11:37.633 +newlines and things. + +00:11:37.633 --> 00:11:43.300 +So in line 1, we define the block just +like you define a function. + +00:11:43.300 --> 00:11:44.880 +We define a block. + +00:11:44.880 --> 00:11:47.433 +The block name is going to be called +"feedback." + +00:11:47.433 --> 00:11:49.680 +It has an author, "who." + +00:11:49.680 --> 00:11:54.133 +The author has no default value. + +00:11:54.133 --> 00:11:57.760 +It has a color, and the color has a +default value of red. + +00:11:57.760 --> 00:12:01.680 +So just as when you define functions, + +00:12:01.680 --> 00:12:06.233 +you start by define or defblock, + +00:12:06.233 --> 00:12:13.440 +then the name, some mandatory argument, +and some optional arguments. + +00:12:13.440 --> 00:12:18.480 +Then the next stage is definition. +Documentation. + +00:12:18.480 --> 00:12:20.133 +The people who use this, + +00:12:20.133 --> 00:12:22.880 +which are future you or future me, + +00:12:22.880 --> 00:12:25.519 +might want to know what this is. + +00:12:25.519 --> 00:12:27.839 +So let's get to document this. + +00:12:27.839 --> 00:12:32.079 +For Corwin, who might want to use +tooltips... + +00:12:32.079 --> 00:12:37.120 +When Corwin writes feedback in Emacs, +they'll see a nice little tooltip, + +00:12:37.120 --> 00:12:38.639 +and the tooltip will have + +00:12:38.639 --> 00:12:41.279 +this documentation string. + +00:12:41.279 --> 00:12:43.279 +That'll be nice. + +00:12:43.279 --> 00:12:45.980 +And then here's the third part. + +00:12:45.980 --> 00:12:48.067 +The last three lines are not so +difficult. + +00:12:48.067 --> 00:12:52.800 +If the backend is HTML, + +00:12:52.800 --> 00:12:55.360 +please use this template string. + +00:12:55.360 --> 00:12:57.440 +Otherwise, use the other string. + +00:12:57.440 --> 00:13:01.279 +For each of these string markers, + +00:13:01.279 --> 00:13:04.959 +please put in the color, who wrote it, +and then the contents + +00:13:04.959 --> 00:13:07.279 +of the special block or the link type. + +00:13:08.160 --> 00:13:11.600 +So that's pretty neat. Not so difficult. + +00:13:11.600 --> 00:13:14.639 +I thought that was kind of cool, + +00:13:14.639 --> 00:13:16.600 +then noticed it's anaphoric. + +00:13:16.600 --> 00:13:21.033 +This defblock gives you two new names. + +00:13:21.033 --> 00:13:23.433 +It gives you a name called contents, + +00:13:23.433 --> 00:13:26.480 +and it gives you a name called backend. + +00:13:26.480 --> 00:13:29.733 +So even if you're writing a defblock + +00:13:29.733 --> 00:13:32.560 +and you intend it to be used +only for links... + +00:13:32.560 --> 00:13:35.440 +Like these colors, for example. + +00:13:35.440 --> 00:13:38.399 +These colors were defined using defblock. + +00:13:38.399 --> 00:13:41.279 +I used them as links right here. + +00:13:41.279 --> 00:13:43.360 +You don't need to worry + +00:13:43.360 --> 00:13:45.300 +where does the text come from +in the link. + +00:13:45.300 --> 00:13:48.959 +If I say "red:Bob," is it Bob? + +00:13:48.959 --> 00:13:52.000 +Or if I put a description, is it the +description? + +00:13:52.000 --> 00:13:54.000 +So it's whatever is available will + +00:13:54.000 --> 00:13:56.720 +become the value of contents. + +00:13:56.720 --> 00:13:59.199 +If you're really interested + +00:13:59.199 --> 00:14:02.433 +and you want to do some intricate stuff, + +00:14:02.433 --> 00:14:06.933 +defblock also gives you something called +raw-contents, + +00:14:06.933 --> 00:14:08.633 +if you really want to touch + +00:14:08.633 --> 00:14:12.639 +the raw contents with all of the Org +markups still there. + +00:14:12.639 --> 00:14:19.440 +Let's see how everyone can communicate +amongst themselves + +00:14:19.440 --> 00:14:22.480 +using this new interface. + +00:14:22.480 --> 00:14:26.000 +So, Sacha speculates and she... How does + +00:14:26.000 --> 00:14:28.399 +she speculate for her Org HTML? + +00:14:28.399 --> 00:14:33.733 +She might just write. Hey look at that, +no HTML, nice. + +00:14:34.800 --> 00:14:36.833 +Amin wants to have some green, + +00:14:36.833 --> 00:14:39.600 +and so he just says, hey here's some +color green. + +00:14:39.600 --> 00:14:42.959 +There you go. It looks almost the same. + +00:14:42.959 --> 00:14:48.267 +Notice that the main argument is right +here. + +00:14:48.267 --> 00:14:49.680 +defblock took an author, + +00:14:49.680 --> 00:14:51.333 +and here's the author again. + +00:14:51.333 --> 00:14:53.920 +And now the optional argument + +00:14:53.920 --> 00:14:57.007 +uses the org babel source interface + +00:14:57.007 --> 00:15:02.867 +You just say :, then a key, and then the +argument. Quite nice. + +00:15:02.867 --> 00:15:07.920 +Corwin doesn't want to use blocks. +It's a bit of an overkill. + +00:15:07.920 --> 00:15:12.959 +He can just write a link. + +00:15:12.959 --> 00:15:17.440 +So the main argument is now +the label of the link, + +00:15:17.440 --> 00:15:23.667 +and the description of the link is the +contents of the feedback. + +00:15:23.667 --> 00:15:25.680 +So that was quite nice. + +00:15:25.680 --> 00:15:29.360 +So it looks like everyone uses the same +interface on the left + +00:15:29.360 --> 00:15:32.800 +and can have varying outputs. + +00:15:32.800 --> 00:15:34.480 +I think it looks quite nice, + +00:15:34.480 --> 00:15:36.639 +and I hope you do too. + +00:15:36.639 --> 00:15:38.800 +There's a few more. + +00:15:38.800 --> 00:15:41.800 +Maybe, as you saw in some previous ones, + +00:15:41.800 --> 00:15:43.920 +we had text side beside side, + +00:15:43.920 --> 00:15:47.440 +or we folded some regions away. + +00:15:47.440 --> 00:15:50.959 +We put some things in pretty boxes. + +00:15:50.959 --> 00:15:57.120 +We had some spoilers at the very +beginning that we hid some text. + +00:15:57.120 --> 00:16:01.680 +We demoed some texts. Here's some Org +and here's what it looks like, + +00:16:01.680 --> 00:16:05.199 +and most importantly, they compose. + +00:16:05.199 --> 00:16:12.639 +There's a a macro called thread-block. + +00:16:12.639 --> 00:16:17.000 +thread-block call, and it lets you +thread the contents + +00:16:17.000 --> 00:16:18.000 +through a number of blocks, + +00:16:18.000 --> 00:16:20.639 +treating them as if they were functions. + +00:16:20.639 --> 00:16:22.480 +So, really, you can think of a block + +00:16:23.680 --> 00:16:25.567 +as a string-valued function. + +00:16:25.567 --> 00:16:28.533 +That's pretty neat, I think. + +00:16:28.533 --> 00:16:30.959 +Thank you for listening. + +00:16:31.759 --> 00:16:34.320 +I hope you've enjoyed this little + +00:16:34.880 --> 00:16:38.160 +happy fun time with the Emacs and +friends. + +00:16:38.160 --> 00:16:43.730 +I'll happily answer questions right now. + +00:16:45.360 --> 00:16:49.467 +Someone says: "Why did you put +optional arguments + +00:16:49.467 --> 00:16:50.480 +in a separate list + +00:16:50.480 --> 00:16:54.560 +rather than using cl-style argument +lists?" + +00:16:54.560 --> 00:16:58.399 +So that's a very good question, + +00:16:58.399 --> 00:17:00.000 +and I will answer that + +00:17:00.000 --> 00:17:05.467 +by showing you a more involved +definition of feedback. + +00:17:05.467 --> 00:17:14.567 +Let's look at a more involved one right +here. + +00:17:14.567 --> 00:17:19.280 +So, for example, this one is +called rremark. + +00:17:19.280 --> 00:17:23.439 +Please let me know if my text is not +sufficiently big. + +00:17:23.439 --> 00:17:28.033 +Here is why we have two arguments. + +00:17:28.033 --> 00:17:30.720 +That takes two arguments instead of one + +00:17:30.720 --> 00:17:33.360 +for its argument list. + +00:17:33.360 --> 00:17:34.799 +You have def block, + +00:17:34.799 --> 00:17:36.000 +then you have the name, + +00:17:36.000 --> 00:17:40.467 +then you have the first argument list + +00:17:40.467 --> 00:17:42.880 +and the second argument list. + +00:17:42.880 --> 00:17:46.080 +The first argument list + +00:17:46.080 --> 00:17:49.280 +takes the text right after the begin. + +00:17:49.280 --> 00:17:53.000 +The text right after the begin is the +main argument. + +00:17:53.000 --> 00:17:59.200 +And then the remaining key-value pairs +are in the second argument list. + +00:18:00.320 --> 00:18:03.280 +Now the reason we have two is because + +00:18:03.280 --> 00:18:08.880 +in order to streamline the interface to +account for both special blocks + +00:18:08.880 --> 00:18:13.360 +and Org link types, what we do is we say, + +00:18:13.360 --> 00:18:18.000 +in the first argument list, you can give +a name to the first argument, + +00:18:18.000 --> 00:18:19.633 +give it a default value, + +00:18:19.633 --> 00:18:28.800 +and anything else you provide will +become part of the link information. + +00:18:28.800 --> 00:18:30.861 +For example, this link, + +00:18:30.861 --> 00:18:32.833 +we decided to make its face +angry red. + +00:18:32.833 --> 00:18:36.433 +You might want to give other +features to links. + +00:18:36.433 --> 00:18:39.100 +So we're trying to streamline +the interface + +00:18:39.100 --> 00:18:41.733 +for both special blocks and +Org link types, + +00:18:41.733 --> 00:18:46.240 +and we thought this way was quite nice. + +00:18:46.240 --> 00:18:47.500 +That was the main reason. + +00:18:47.500 --> 00:18:52.480 +Someone asks-- + +00:18:52.480 --> 00:18:55.039 +if you have follow-ups, please ask-- + +00:18:55.039 --> 00:18:57.600 +Someone asks, "Do you intend to try to + +00:18:57.600 --> 00:19:00.559 +upstream this amazing work into Org?" + +00:19:00.559 --> 00:19:02.300 +Well, I'm glad you like it. + +00:19:02.300 --> 00:19:04.559 +I don't know how to upstream, + +00:19:04.559 --> 00:19:06.400 +but I will look into it, + +00:19:06.400 --> 00:19:09.833 +and any advice or guidance +would be much appreciated. + +00:19:11.840 --> 00:19:15.267 +Lisp is awesome. Just as +defun is a macro, + +00:19:15.267 --> 00:19:17.120 +defblock is a macro, and then + +00:19:17.120 --> 00:19:20.240 +source blocks are awesome. + +00:19:20.240 --> 00:19:22.467 +Now maybe we can have arguments in +special blocks, + +00:19:22.467 --> 00:19:28.799 +and motivate and encourage more +people to learn Lisp. + +00:19:28.799 --> 00:19:32.559 +So another person asks, + +00:19:32.559 --> 00:19:35.280 +"What is used to produce colorful + +00:19:35.280 --> 00:19:38.559 +boxes around the cursor?" + +00:19:38.559 --> 00:19:40.400 +I'm not quite sure if you're asking... + +00:19:40.400 --> 00:19:42.559 +Are you talking about my cursor +right here, + +00:19:42.559 --> 00:19:48.400 +or are you talking about in the slide? + +00:19:48.400 --> 00:19:53.767 +So this cursor is some application +called Streambrush, + +00:19:53.767 --> 00:19:55.440 +that I had to purchase. + +00:19:55.440 --> 00:19:59.039 +Unfortunately, I could not find a a +suitable free one. + +00:19:59.039 --> 00:20:03.067 +The blocks... I can demonstrate some +Emacs Lisp. + +00:20:03.067 --> 00:20:04.467 +I can open up my Emacs, if people like, + +00:20:04.467 --> 00:20:06.320 +and we can try some things out. + +00:20:06.320 --> 00:20:09.440 +Happy to do that. + +00:20:09.440 --> 00:20:10.133 +You're welcome. + +00:20:10.133 --> 00:20:15.520 +Someone asks a side question about +org-reveal: "How do you get + +00:20:15.520 --> 00:20:17.440 +bespoke or multiple-column layouts + +00:20:17.440 --> 00:20:19.120 +without using HTML?" + +00:20:19.120 --> 00:20:22.559 +Excellent question. That's what we do. + +00:20:22.559 --> 00:20:25.533 +That's what this project is about. + +00:20:25.533 --> 00:20:27.000 +So it's not org-reveal, + +00:20:27.000 --> 00:20:30.267 +it's our fancy parallel block. + +00:20:30.267 --> 00:20:33.440 +So we have this thing. You say, +#+begin_parallel. + +00:20:33.440 --> 00:20:35.679 +You say how many columns you would like. + +00:20:35.679 --> 00:20:37.967 +Do you want a bar or not? + +00:20:37.967 --> 00:20:39.679 +And then you write some text, + +00:20:39.679 --> 00:20:44.400 +and then you get some text, and +according with the bar or not. + +00:20:44.400 --> 00:20:47.520 +That's how we achieve that in our slides. + +00:20:47.520 --> 00:20:52.880 +I'm not quite sure where this was. + +00:20:52.880 --> 00:20:59.520 +Somewhere here, I think. + +00:20:59.520 --> 00:21:06.240 +Let me try to find this for you. + +00:21:06.240 --> 00:21:10.433 +I can't seem to find where the parallel +blocks were. Apologies. + +00:21:10.433 --> 00:21:15.039 +Let's move on to the next question, +I suppose. + +00:21:15.039 --> 00:21:18.400 +I'm pretty sure they're here. Ah, there +they are. + +00:21:18.400 --> 00:21:22.640 +So these were just instances of using + +00:21:22.640 --> 00:21:26.480 +the parallel block, and it makes things +parallel. + +00:21:26.480 --> 00:21:27.633 +So that's quite nice. + +00:21:27.633 --> 00:21:33.360 +Another person asks, + +00:21:33.360 --> 00:21:37.840 +"How does this relate to pandoc, + +00:21:37.840 --> 00:21:40.960 +which is used for converting between +markup formats?" + +00:21:40.960 --> 00:21:43.919 +So all we're doing is we're saying, + +00:21:43.919 --> 00:21:47.679 +hey, please write Org because Org is +just fantastic, + +00:21:47.679 --> 00:21:49.267 +and we love it, and it's the dream, + +00:21:49.267 --> 00:21:51.760 +and if you would like to view things + +00:21:51.760 --> 00:21:55.900 +in HTML, or in org-reveal, or in PDF, + +00:21:55.900 --> 00:21:58.559 +that's up to the user. + +00:22:02.320 --> 00:22:06.080 +Made it too small now. +So here is an example. + +00:22:06.080 --> 00:22:10.240 +Here's how parallel is implemented, + +00:22:10.240 --> 00:22:14.320 +just as a quick example, not too long. + +00:22:14.320 --> 00:22:17.800 +About half of the implementation is +documentation, + +00:22:17.800 --> 00:22:22.720 +so, hopefully, that speaks for for how +useful this feature is. + +00:22:22.720 --> 00:22:25.280 +We decide if there's a rule or not. + +00:22:25.280 --> 00:22:28.080 +We look for the column break. + +00:22:28.080 --> 00:22:30.600 +Here we're looking at the backend. + +00:22:30.600 --> 00:22:31.840 +If the backend is LaTeX, + +00:22:31.840 --> 00:22:34.133 +please use this incantation + +00:22:34.133 --> 00:22:37.679 +with multicolumns, minipages, +what have you. + +00:22:37.679 --> 00:22:41.600 +If the backend is something else, please +do this: + +00:22:41.600 --> 00:22:48.080 +div, style and other gibberish that we +don't really want to look at. + +00:22:48.080 --> 00:22:51.760 +Pandoc works from Org, + +00:22:51.760 --> 00:22:53.633 +so it might not work directly, + +00:22:53.633 --> 00:22:59.679 +since our interface... The way we set it +up is: when you try to export, + +00:22:59.679 --> 00:23:03.039 +we hook in and we do a bunch of +pre-processing, + +00:23:03.039 --> 00:23:07.440 +so this defblock is a +string-valued function. + +00:23:07.440 --> 00:23:13.919 +Whenever we see these #+begin_parallel +when you do an export, + +00:23:13.919 --> 00:23:17.767 +I tell Emacs, hold up, look for those +#+begin_parallels, please. + +00:23:17.767 --> 00:23:20.320 +Oh, you found them? Grab that text. + +00:23:20.320 --> 00:23:21.533 +You grabbed it. Great. + +00:23:21.533 --> 00:23:24.080 +Now please apply this person's function + +00:23:24.080 --> 00:23:27.120 +onto that text, and splice in the result. + +00:23:27.120 --> 00:23:30.400 +So when you export, we're performing + +00:23:30.400 --> 00:23:35.120 +arbitrary computations on your text. + +00:23:35.120 --> 00:23:39.633 +Some people might not find that +comforting, + +00:23:39.633 --> 00:23:43.039 +to have arbitrary computations happening. + +00:23:43.039 --> 00:23:45.039 +In this article, there's a few where + +00:23:45.039 --> 00:23:47.167 +we change your text upon export. + +00:23:47.167 --> 00:23:51.760 +We translate it, we do other things +to it. + +00:23:51.760 --> 00:23:56.500 +So someone says, "If you export to +LaTeX, to PDF, + +00:23:56.500 --> 00:23:58.640 +does that work well with Beamer as well + +00:23:58.640 --> 00:24:00.320 +to create slides with columns?" + +00:24:05.200 --> 00:24:08.000 +I made a bunch of these changes + +00:24:08.000 --> 00:24:09.200 +earlier this morning, + +00:24:09.200 --> 00:24:12.320 +and it just says LaTeX right here. + +00:24:12.320 --> 00:24:14.400 +So if you want to go to beamer, + +00:24:14.400 --> 00:24:15.360 +I think the back end for me, + +00:24:15.360 --> 00:24:17.333 +beamer is called, well, beamer, + +00:24:17.333 --> 00:24:22.000 +so instead of a pcase, what we would do +is, we would say, + +00:24:22.000 --> 00:24:27.167 +if it's a 'latex or it's a 'beamer, then +use this. + +00:24:27.167 --> 00:24:30.267 +Otherwise, it's not a LaTeX, + +00:24:30.267 --> 00:24:31.867 +it will simply default to this one, + +00:24:31.867 --> 00:24:34.433 +which could be dangerous +for your needs. + +00:24:34.433 --> 00:24:39.167 +I think it's a bad practice to put a +underscore, + +00:24:39.167 --> 00:24:40.767 +but I did it really quickly + +00:24:40.767 --> 00:24:44.500 +because I just wanted to show you that +it works fine in org-reveal + +00:24:44.500 --> 00:24:47.440 +Contributions are more than welcome. + +00:24:47.440 --> 00:24:52.240 +I happily would love any assistance. + +00:24:52.240 --> 00:24:58.633 +We have a Lisp reference +cheat sheet here + +00:24:58.633 --> 00:25:01.000 +to learn a little bit about Lisp, if +you're not comfortable, + +00:25:01.000 --> 00:25:03.267 +or to ask some questions. + +00:25:03.267 --> 00:25:06.400 +Lots of helpful people. + +00:25:06.400 --> 00:25:09.440 +So there's another question that says, + +00:25:09.440 --> 00:25:13.120 +"Does typing in a block mess up with +syntax highlighting? + +00:25:13.120 --> 00:25:15.679 +Usually, you use a single color inside an + +00:25:15.679 --> 00:25:17.279 +example block, for example. + +00:25:17.279 --> 00:25:21.279 +Ah, you found my crutch. + +00:25:25.279 --> 00:25:27.333 +Emacs is all encompassing, + +00:25:27.333 --> 00:25:29.760 +and I'm not quite sure how fonts work. + +00:25:29.760 --> 00:25:32.559 +I learned enough to get by. + +00:25:37.440 --> 00:25:38.667 +Here's how links work. + +00:25:38.667 --> 00:25:40.799 +They're a bit complicated. + +00:25:40.799 --> 00:25:42.567 +This is a bit scary. + +00:25:42.567 --> 00:25:47.039 +I don't recommend anyone read it. + +00:25:47.039 --> 00:25:49.840 +Actually, let me open up an email + +00:25:50.559 --> 00:25:52.100 +and you can see what I see. + +00:25:52.100 --> 00:25:54.799 +So here's an Emacs. + +00:25:54.799 --> 00:25:56.799 +Let's make that a bit bigger. + +00:25:56.799 --> 00:25:59.133 +Let's change this slightly. + +00:25:59.133 --> 00:26:01.200 +Nope, that's worse. There you go. + +00:26:01.919 --> 00:26:09.360 +Here's some words.

-00:01:45.280 --> 00:01:47.119 -there are language specific persons - -00:01:47.119 --> 00:01:48.640 -written in elise - -00:01:48.640 --> 00:01:50.240 -they can be thought of as the next - -00:01:50.240 --> 00:01:52.320 -logical step of the glue code on top - -00:01:52.320 --> 00:01:54.960 -of tribal expressions moving from - -00:01:54.960 --> 00:01:56.000 -partial local - -00:01:56.000 --> 00:01:58.079 -pattern recognition into a full-fledged - -00:01:58.079 --> 00:01:59.840 -parser - -00:01:59.840 --> 00:02:01.439 -the most prominent example of this - -00:02:01.439 --> 00:02:03.040 -approach is probably the famous - -00:02:03.040 --> 00:02:06.479 -js2 mode - -00:02:06.479 --> 00:02:10.080 -however this approach has several issues - -00:02:10.080 --> 00:02:12.959 -parsing is computationally expensive and - -00:02:12.959 --> 00:02:13.680 -imagine - -00:02:13.680 --> 00:02:16.800 -is not good at that kind of stuff - -00:02:16.800 --> 00:02:18.400 -furthermore maintenance is very - -00:02:18.400 --> 00:02:20.840 -troublesome in order to work on these - -00:02:20.840 --> 00:02:22.160 -process - -00:02:22.160 --> 00:02:23.599 -first you have to know at least well - -00:02:23.599 --> 00:02:25.599 -enough and then you have to be - -00:02:25.599 --> 00:02:27.760 -comfortable with writing a - -00:02:27.760 --> 00:02:30.319 -recursive ascendant parser while - -00:02:30.319 --> 00:02:32.080 -constantly keeping up with changes to - -00:02:32.080 --> 00:02:34.000 -the language itself - -00:02:34.000 --> 00:02:36.879 -which can be evolving very quickly like - -00:02:36.879 --> 00:02:39.360 -javascript for example - -00:02:39.360 --> 00:02:41.599 -together these constraints significantly - -00:02:41.599 --> 00:02:45.680 -reduce the pull of potential maintenance - -00:02:45.680 --> 00:02:47.760 -the biggest issue though in my opinion - -00:02:47.760 --> 00:02:49.680 -is lack of the set of generic - -00:02:49.680 --> 00:02:52.879 -and reusable apis this makes them very - -00:02:52.879 --> 00:02:54.319 -hard to use - -00:02:54.319 --> 00:02:55.920 -for minor modes that want to deal with - -00:02:55.920 --> 00:02:57.920 -cross-cutting concerns across multiple - -00:02:57.920 --> 00:02:59.920 -languages - -00:02:59.920 --> 00:03:01.760 -the other approach which has been - -00:03:01.760 --> 00:03:03.599 -gaining a lot of momentum in recent - -00:03:03.599 --> 00:03:04.319 -years - -00:03:04.319 --> 00:03:06.560 -is externalizing language understanding - -00:03:06.560 --> 00:03:08.159 -to another process - -00:03:08.159 --> 00:03:12.239 -also known as language server protocol - -00:03:12.239 --> 00:03:14.480 -this second approach is actually a very - -00:03:14.480 --> 00:03:16.560 -interesting one - -00:03:16.560 --> 00:03:18.400 -my decoupling language understanding - -00:03:18.400 --> 00:03:21.280 -from the editing facility itself - -00:03:21.280 --> 00:03:23.760 -the usb servers can attract a lot more - -00:03:23.760 --> 00:03:25.120 -contributors - -00:03:25.120 --> 00:03:28.959 -which makes maintenance easier however - -00:03:28.959 --> 00:03:32.400 -they also have several issues available - -00:03:32.400 --> 00:03:34.720 -being a separate process they are - -00:03:34.720 --> 00:03:36.000 -usually more resource - -00:03:36.000 --> 00:03:39.920 -intensive and depending on the language - -00:03:39.920 --> 00:03:42.159 -the usb server itself can bring with it - -00:03:42.159 --> 00:03:44.640 -a host of additional dependencies - -00:03:44.640 --> 00:03:47.680 -external to Emacs which may message to - -00:03:47.680 --> 00:03:50.640 -install and manage - -00:03:50.640 --> 00:03:53.760 -furthermore json over rpc has pretty - -00:03:53.760 --> 00:03:55.120 -high latency - -00:03:55.120 --> 00:03:57.840 -for one-off tasks like jumping to source - -00:03:57.840 --> 00:04:00.879 -or on-demand completion is great - -00:04:00.879 --> 00:04:03.040 -but for things like code highlighting - -00:04:03.040 --> 00:04:06.000 -the latency is just too much - -00:04:06.000 --> 00:04:08.319 -I was using rust and I was following the - -00:04:08.319 --> 00:04:10.480 -community effort to improve its id - -00:04:10.480 --> 00:04:11.760 -support - -00:04:11.760 --> 00:04:13.680 -hoping to integrate some of that into - -00:04:13.680 --> 00:04:15.760 -Emacs itself - -00:04:15.760 --> 00:04:17.600 -then I heard someone from community - -00:04:17.600 --> 00:04:19.759 -mention tree sitter - -00:04:19.759 --> 00:04:23.360 -and I decided to check it out - -00:04:23.360 --> 00:04:25.520 -basically trisita is an incremental - -00:04:25.520 --> 00:04:28.720 -parsing library and a parser generator - -00:04:28.720 --> 00:04:31.000 -it was introduced by the item editor in - -00:04:31.000 --> 00:04:33.040 -2018 - -00:04:33.040 --> 00:04:35.680 -besides item is also being integrated - -00:04:35.680 --> 00:04:36.960 -into the neo-vim - -00:04:36.960 --> 00:04:41.040 -editor and github is using it to power - -00:04:41.040 --> 00:04:42.479 -their source code analysis and - -00:04:42.479 --> 00:04:45.840 -navigation features - -00:04:45.840 --> 00:04:48.639 -it is written in c and can be compiled - -00:04:48.639 --> 00:04:49.199 -for all - -00:04:49.199 --> 00:04:53.120 -major platforms it can even be compiled - -00:04:53.120 --> 00:04:56.080 -to web assembly to run on the web that's - -00:04:56.080 --> 00:04:57.600 -how github is using it - -00:04:57.600 --> 00:05:00.800 -on their website - -00:05:00.800 --> 00:05:02.960 -so why is trisita an interesting - -00:05:02.960 --> 00:05:05.840 -solution to this problem - -00:05:05.840 --> 00:05:07.360 -there are multiple features that make it - -00:05:07.360 --> 00:05:10.000 -an attractive option - -00:05:10.000 --> 00:05:12.400 -it is designed to be fast by being - -00:05:12.400 --> 00:05:13.680 -incremental - -00:05:13.680 --> 00:05:15.680 -the initial parts of a typical big fight - -00:05:15.680 --> 00:05:18.160 -can take tens of milliseconds - -00:05:18.160 --> 00:05:20.240 -while subsequent incremental processes - -00:05:20.240 --> 00:05:22.560 -are sub milliseconds - -00:05:22.560 --> 00:05:24.720 -it achieves this by using structural - -00:05:24.720 --> 00:05:26.240 -sharing - -00:05:26.240 --> 00:05:29.360 -meaning replacing only affected nodes - -00:05:29.360 --> 00:05:32.960 -in the old tree when it needs to - -00:05:32.960 --> 00:05:36.000 -also unlike lsp being in the same - -00:05:36.000 --> 00:05:37.120 -process - -00:05:37.120 --> 00:05:40.639 -it has much lower latency - -00:05:40.639 --> 00:05:42.880 -secondly it provides a uniform - -00:05:42.880 --> 00:05:44.960 -programming interface - -00:05:44.960 --> 00:05:47.039 -the same data structures and functions - -00:05:47.039 --> 00:05:48.720 -work on parse trees of different - -00:05:48.720 --> 00:05:50.400 -languages - -00:05:50.400 --> 00:05:52.160 -syntax knows of different languages - -00:05:52.160 --> 00:05:54.160 -differ only by their types - -00:05:54.160 --> 00:05:57.360 -and their possible child nodes this - -00:05:57.360 --> 00:05:58.960 -is a big advantage over language - -00:05:58.960 --> 00:06:02.240 -specific parcels - -00:06:02.240 --> 00:06:04.880 -thirdly it's written in self-contained - -00:06:04.880 --> 00:06:06.880 -embeddable c - -00:06:06.880 --> 00:06:09.680 -as I mentioned previously it can even be - -00:06:09.680 --> 00:06:10.400 -compiled - -00:06:10.400 --> 00:06:13.759 -to webassembly this makes integrating it - -00:06:13.759 --> 00:06:15.199 -into various editors - -00:06:15.199 --> 00:06:18.240 -quite easy without having to install - -00:06:18.240 --> 00:06:22.880 -any external dependencies - -00:06:22.880 --> 00:06:24.639 -one thing that is not mentioned here is - -00:06:24.639 --> 00:06:28.000 -that being a parcel generator - -00:06:28.000 --> 00:06:31.039 -scrummers are declarative - -00:06:31.039 --> 00:06:34.880 -together with being editor independent - -00:06:34.880 --> 00:06:36.720 -this makes the pool of potential - -00:06:36.720 --> 00:06:38.160 -contributors - -00:06:38.160 --> 00:06:42.400 -much larger so I was convinced - -00:06:42.400 --> 00:06:45.520 -that trisito is a good fit for Emacs - -00:06:45.520 --> 00:06:48.000 -last year I started writing the bindings - -00:06:48.000 --> 00:06:48.720 -using - -00:06:48.720 --> 00:06:50.960 -dynamic model support introduced in imax - -00:06:50.960 --> 00:06:53.280 -25. - -00:06:53.280 --> 00:06:55.360 -dynamic module means there is platform - -00:06:55.360 --> 00:06:58.479 -specific native code involved - -00:06:58.479 --> 00:07:00.560 -but since they are pre-compiled binaries - -00:07:00.560 --> 00:07:02.880 -for the three major platforms - -00:07:02.880 --> 00:07:06.319 -it should work in most places currently - -00:07:06.319 --> 00:07:08.319 -the core functionalities are in a pretty - -00:07:08.319 --> 00:07:09.440 -good shape - -00:07:09.440 --> 00:07:12.560 -syntax highlighting is working nicely - -00:07:12.560 --> 00:07:14.840 -the whole thing is split into three - -00:07:14.840 --> 00:07:16.080 -packages - -00:07:16.080 --> 00:07:17.759 -tree sitter is the main package that - -00:07:17.759 --> 00:07:20.319 -other packages should depend on - -00:07:20.319 --> 00:07:22.800 -tree system lens is the language bundle - -00:07:22.800 --> 00:07:24.000 -that includes support - -00:07:24.000 --> 00:07:27.199 -for most common languages - -00:07:27.199 --> 00:07:30.080 -and finally the core apis are in the - -00:07:30.080 --> 00:07:32.160 -package tsc - -00:07:32.160 --> 00:07:36.160 -which stands for trees the core - -00:07:36.160 --> 00:07:38.800 -it is the implicit dependency of the - -00:07:38.800 --> 00:07:43.520 -three-seater package - -00:07:43.520 --> 00:07:46.000 -the main package includes the miner mode - -00:07:46.000 --> 00:07:47.520 -3-seater mode - -00:07:47.520 --> 00:07:49.840 -this provides the base for other major - -00:07:49.840 --> 00:07:52.560 -or minor modes to build on - -00:07:52.560 --> 00:07:55.280 -using image change tracking hooks it - -00:07:55.280 --> 00:07:55.840 -enables - -00:07:55.840 --> 00:07:58.080 -incremental parsing and provides a - -00:07:58.080 --> 00:08:00.800 -syntax tree that is always up to date - -00:08:00.800 --> 00:08:04.080 -after any edits in a buffer - -00:08:04.080 --> 00:08:06.560 -there is also a basic debug mode that - -00:08:06.560 --> 00:08:10.080 -shows the parse tree in another buffer - -00:08:10.080 --> 00:08:13.360 -here is a quick demo - -00:08:13.360 --> 00:08:15.759 -here I mean an empty python buffer with - -00:08:15.759 --> 00:08:17.520 -three seater enabled - -00:08:17.520 --> 00:08:19.440 -I'm going to turn on the debug mode to - -00:08:19.440 --> 00:08:26.560 -see the parse tree - -00:08:26.560 --> 00:08:28.720 -since the buffer is empty there is only - -00:08:28.720 --> 00:08:30.639 -one node in the syntax tree the top - -00:08:30.639 --> 00:08:33.279 -level module node - -00:08:33.279 --> 00:09:11.040 -let's try typing some code - -00:09:11.040 --> 00:09:13.600 -as you can see as I type into the python - -00:09:13.600 --> 00:09:14.640 -buffer - -00:09:14.640 --> 00:09:19.120 -the syntax tree updates in real time - -00:09:19.120 --> 00:09:21.120 -the other minor mode included in the - -00:09:21.120 --> 00:09:23.279 -main package is 3-seater - -00:09:23.279 --> 00:09:26.640 -hl mode it overrides font-lock mode and - -00:09:26.640 --> 00:09:28.480 -provides its own set of phases - -00:09:28.480 --> 00:09:31.839 -and customization options it is query - -00:09:31.839 --> 00:09:32.800 -driven - -00:09:32.800 --> 00:09:35.200 -that means instead of regular - -00:09:35.200 --> 00:09:36.240 -expressions - -00:09:36.240 --> 00:09:38.720 -it uses a list like query language to - -00:09:38.720 --> 00:09:40.320 -map syntax notes - -00:09:40.320 --> 00:09:43.760 -to highlighting phrases I'm going to - -00:09:43.760 --> 00:09:45.760 -open a python file with small snippets - -00:09:45.760 --> 00:09:54.320 -that showcase syntax highlighting - -00:09:54.320 --> 00:09:55.920 -so this is the default highlighting - -00:09:55.920 --> 00:10:00.880 -provided by python mode - -00:10:00.880 --> 00:10:02.839 -this is the highlighting enabled by tree - -00:10:02.839 --> 00:10:04.640 -sitter - -00:10:04.640 --> 00:10:07.680 -as you can see string interpolation - -00:10:07.680 --> 00:10:11.680 -and decorators are highlighted correctly - -00:10:11.680 --> 00:10:17.440 -function calls are also highlighted - -00:10:17.440 --> 00:10:20.240 -you can also note that property - -00:10:20.240 --> 00:10:21.839 -assessors - -00:10:21.839 --> 00:10:24.640 -and property assignments are highlighted - -00:10:24.640 --> 00:10:27.440 -differently - -00:10:27.440 --> 00:10:29.360 -what I like the most about this is that - -00:10:29.360 --> 00:10:30.880 -new bindings are consistently - -00:10:30.880 --> 00:10:32.640 -highlighted - -00:10:32.640 --> 00:10:36.320 -this included local variable - -00:10:36.320 --> 00:10:39.760 -function parameters and property - -00:10:39.760 --> 00:10:45.760 -mutations - -00:10:45.760 --> 00:10:48.000 -before going through the three queries - -00:10:48.000 --> 00:10:49.279 -and the syntax highlighting - -00:10:49.279 --> 00:10:51.680 -customization options - -00:10:51.680 --> 00:10:53.760 -let's take a brief look at the core data - -00:10:53.760 --> 00:10:55.040 -structures and functions - -00:10:55.040 --> 00:10:58.079 -that tree sitter provides - -00:10:58.079 --> 00:10:59.839 -so parsing is done with the help of a - -00:10:59.839 --> 00:11:02.240 -generic parser object - -00:11:02.240 --> 00:11:04.160 -a single parser object can be used to - -00:11:04.160 --> 00:11:06.000 -pass different languages - -00:11:06.000 --> 00:11:08.320 -by sending different language objects to - -00:11:08.320 --> 00:11:09.279 -it - -00:11:09.279 --> 00:11:10.880 -the language objects themselves are - -00:11:10.880 --> 00:11:14.079 -loaded from shared libraries - -00:11:14.079 --> 00:11:16.079 -since three seater mode already handles - -00:11:16.079 --> 00:11:17.360 -the parsing part - -00:11:17.360 --> 00:11:19.440 -we will instead focus on the functions - -00:11:19.440 --> 00:11:20.800 -that inspect nodes - -00:11:20.800 --> 00:11:25.279 -and in the resulting path tree - -00:11:25.279 --> 00:11:27.200 -we can ask tree sitter what is the - -00:11:27.200 --> 00:11:44.240 -syntax node at point - -00:11:44.240 --> 00:11:47.200 -uh is it an opaque object so this is not - -00:11:47.200 --> 00:11:48.480 -very useful - -00:11:48.480 --> 00:12:03.760 -we can instead ask what is its type - -00:12:03.760 --> 00:12:06.560 -so his type is the symbol comparison - -00:12:06.560 --> 00:12:08.959 -operator - -00:12:08.959 --> 00:12:11.600 -trees there are two kinds of nodes - -00:12:11.600 --> 00:12:13.680 -anonymous nodes and named nodes - -00:12:13.680 --> 00:12:15.519 -anonymous nodes correspond to simple - -00:12:15.519 --> 00:12:17.040 -grammar elements - -00:12:17.040 --> 00:12:19.839 -like keywords operators punctuations and - -00:12:19.839 --> 00:12:21.279 -so on - -00:12:21.279 --> 00:12:24.160 -name nodes on the other hand grammar - -00:12:24.160 --> 00:12:25.920 -elements that are interesting enough for - -00:12:25.920 --> 00:12:26.639 -their own - -00:12:26.639 --> 00:12:30.320 -to have a name like an identifier an - -00:12:30.320 --> 00:12:31.839 -expression - -00:12:31.839 --> 00:12:35.440 -or a function definition - -00:12:35.440 --> 00:12:37.760 -name node types are symbols while - -00:12:37.760 --> 00:12:42.639 -anonymous node types are strings - -00:12:42.639 --> 00:12:46.320 -for example if we are on this - -00:12:46.320 --> 00:12:49.760 -comparison operator - -00:12:49.760 --> 00:12:55.920 -the node type should be a string - -00:12:55.920 --> 00:12:57.920 -we can also get other information about - -00:12:57.920 --> 00:12:58.959 -the node - -00:12:58.959 --> 00:13:09.680 -for example what is this text - -00:13:09.680 --> 00:13:20.800 -or where it is in the buffer - -00:13:20.800 --> 00:13:43.199 -or what is its parent - -00:13:43.199 --> 00:13:46.160 -there are many other apis to query or - -00:13:46.160 --> 00:13:46.839 -not - -00:13:46.839 --> 00:13:52.639 -properties - -00:13:52.639 --> 00:13:54.399 -tree sitter allows searching for - -00:13:54.399 --> 00:13:58.240 -structural patterns within a parse tree - -00:13:58.240 --> 00:14:01.440 -it does so through a list like language - -00:14:01.440 --> 00:14:03.519 -this language supports by the matching - -00:14:03.519 --> 00:14:04.639 -by node types - -00:14:04.639 --> 00:14:07.760 -field names and predicates - -00:14:07.760 --> 00:14:10.079 -it also allows capturing nodes for - -00:14:10.079 --> 00:14:12.639 -further processing - -00:14:12.639 --> 00:14:37.680 -let's try to see some examples - -00:14:37.680 --> 00:14:41.040 -so in this very simple query we just - -00:14:41.040 --> 00:14:43.839 -try to highlight all the identifiers in - -00:14:43.839 --> 00:14:49.040 -the buffer - -00:14:49.040 --> 00:14:51.920 -this s side tells trisito to capture a - -00:14:51.920 --> 00:14:53.120 -node - -00:14:53.120 --> 00:14:55.839 -in the context of the query builder it's - -00:14:55.839 --> 00:14:57.360 -not very important - -00:14:57.360 --> 00:15:00.320 -but in normal highlighting query this - -00:15:00.320 --> 00:15:01.760 -will determine - -00:15:01.760 --> 00:15:06.639 -the face used to highlight the note - -00:15:06.639 --> 00:15:08.800 -suppose we want to capture all the - -00:15:08.800 --> 00:15:10.320 -function names - -00:15:10.320 --> 00:15:13.519 -instead of just any identifier - -00:15:13.519 --> 00:15:29.440 -you can improve the query like this - -00:15:29.440 --> 00:15:31.600 -uh this will highlight the whole - -00:15:31.600 --> 00:15:32.639 -definition - -00:15:32.639 --> 00:15:35.519 -but we only want to capture the function - -00:15:35.519 --> 00:15:36.399 -name - -00:15:36.399 --> 00:15:39.600 -which means the identifier - -00:15:39.600 --> 00:15:42.800 -here so we - -00:15:42.800 --> 00:15:46.320 -move the capture to after the identifier - -00:15:46.320 --> 00:15:49.600 -node - -00:15:49.600 --> 00:15:51.759 -if we want to capture the class names as - -00:15:51.759 --> 00:15:52.959 -well - -00:15:52.959 --> 00:16:10.079 -we just add another pattern - -00:16:10.079 --> 00:16:20.320 -let's look at a more practical example - -00:16:20.320 --> 00:16:22.959 -here we can see that single quotes - -00:16:22.959 --> 00:16:23.759 -strings and - -00:16:23.759 --> 00:16:25.600 -double quotes screens are highlighted - -00:16:25.600 --> 00:16:27.279 -the same - -00:16:27.279 --> 00:16:30.399 -but in some places - -00:16:30.399 --> 00:16:33.440 -because of some coding conventions - -00:16:33.440 --> 00:16:35.440 -it may be desirable to highlight them - -00:16:35.440 --> 00:16:37.279 -differently for example if - -00:16:37.279 --> 00:16:39.680 -the string is single quoted we may want - -00:16:39.680 --> 00:16:40.880 -to highlight it - -00:16:40.880 --> 00:16:44.399 -as a constant - -00:16:44.399 --> 00:16:46.160 -let's try to see whether we can - -00:16:46.160 --> 00:16:47.600 -distinguish these - -00:16:47.600 --> 00:16:56.240 -two cases - -00:16:56.240 --> 00:17:00.639 -so here we get all the strings - -00:17:00.639 --> 00:17:04.079 -if we want to see if it's single quotes - -00:17:04.079 --> 00:17:04.559 -or - -00:17:04.559 --> 00:17:08.799 -double quote strings - -00:17:08.799 --> 00:17:11.039 -we can try looking at the first - -00:17:11.039 --> 00:17:12.480 -character - -00:17:12.480 --> 00:17:15.280 -of the string I mean the first character - -00:17:15.280 --> 00:17:16.720 -of the note - -00:17:16.720 --> 00:17:19.360 -to check whether it's a single quote or - -00:17:19.360 --> 00:17:33.600 -a double quote - -00:17:33.600 --> 00:17:36.080 -yeah so for that we use the three - -00:17:36.080 --> 00:17:36.799 -setters - -00:17:36.799 --> 00:17:40.160 -support for predicate in this case - -00:17:40.160 --> 00:17:43.360 -we use a match predicate - -00:17:43.360 --> 00:17:46.080 -to check whether the string where the - -00:17:46.080 --> 00:17:46.799 -note - -00:17:46.799 --> 00:17:50.320 -starts with a single quote and with this - -00:17:50.320 --> 00:17:51.280 -pattern - -00:17:51.280 --> 00:17:58.840 -we only capture the single quotes - -00:17:58.840 --> 00:18:00.400 -strings - -00:18:00.400 --> 00:18:03.760 -let's try to give it a different face - -00:18:03.760 --> 00:18:13.039 -so we copy the pattern - -00:18:13.039 --> 00:18:18.640 -and we add this pattern - -00:18:18.640 --> 00:18:25.120 -pop item only - -00:18:25.120 --> 00:18:28.400 -but we also want to give the - -00:18:28.400 --> 00:18:31.440 -capture a different name - -00:18:31.440 --> 00:18:40.840 -let's say we want to highlight it as a - -00:18:40.840 --> 00:18:46.559 -keyword - -00:18:46.559 --> 00:19:06.320 -and now if we refresh the buffer - -00:19:06.320 --> 00:19:08.799 -we see that single quote strings are - -00:19:08.799 --> 00:19:10.320 -highlighted as - -00:19:10.320 --> 00:19:14.400 -keywords - -00:19:14.400 --> 00:19:16.400 -the highlighting patterns can also be - -00:19:16.400 --> 00:19:19.200 -set for a single project - -00:19:19.200 --> 00:19:23.440 -using directory local variable - -00:19:23.440 --> 00:19:26.880 -for example let's take a look at - -00:19:26.880 --> 00:19:35.760 -ems source code - -00:19:35.760 --> 00:19:40.400 -so in image c source there are a lot of - -00:19:40.400 --> 00:19:43.760 -uses of these different macros - -00:19:43.760 --> 00:19:47.679 -to define functions - -00:19:47.679 --> 00:19:51.200 -and you can see - -00:19:51.200 --> 00:19:53.520 -this is actually the function name but - -00:19:53.520 --> 00:19:55.760 -it's highlighted as the - -00:19:55.760 --> 00:19:59.120 -string so what we want - -00:19:59.120 --> 00:20:03.679 -is to somehow recognize this pattern - -00:20:03.679 --> 00:20:07.600 -and highlight it - -00:20:07.600 --> 00:20:11.280 -as highlight this part - -00:20:11.280 --> 00:20:14.559 -with the function phase instead - -00:20:14.559 --> 00:20:17.679 -in order to do that - -00:20:17.679 --> 00:20:20.240 -we put a pattern in this project - -00:20:20.240 --> 00:20:21.760 -directory local - -00:20:21.760 --> 00:20:31.760 -settings file - -00:20:31.760 --> 00:20:34.799 -so we can put this button in the c - -00:20:34.799 --> 00:20:40.159 -mode section - -00:20:40.159 --> 00:20:48.000 -and now if we enable tree sitter - -00:20:48.000 --> 00:20:50.480 -you can see that this is the highlighted - -00:20:50.480 --> 00:20:53.200 -uh - -00:20:53.200 --> 00:20:55.520 -as a normal function definition so this - -00:20:55.520 --> 00:20:56.559 -is the function - -00:20:56.559 --> 00:21:01.200 -face like we wanted - -00:21:01.200 --> 00:21:03.760 -the pattern for this is actually pretty - -00:21:03.760 --> 00:21:07.200 -simple - -00:21:07.200 --> 00:21:10.720 -it's only - -00:21:10.720 --> 00:21:14.720 -only this part so - -00:21:14.720 --> 00:21:17.440 -if it's a function call where the name - -00:21:17.440 --> 00:21:19.679 -of the function is different - -00:21:19.679 --> 00:21:21.600 -then we highlight the different as a - -00:21:21.600 --> 00:21:24.240 -keyword - -00:21:24.240 --> 00:21:27.360 -and then the first string element we - -00:21:27.360 --> 00:21:28.159 -highlighted - -00:21:28.159 --> 00:21:35.360 -as a function name - -00:21:35.360 --> 00:21:37.679 -since the language objects are actually - -00:21:37.679 --> 00:21:39.280 -native code - -00:21:39.280 --> 00:21:40.799 -they have to be compiled for each - -00:21:40.799 --> 00:21:43.440 -platform that we want to support - -00:21:43.440 --> 00:21:45.600 -this will become a big obstacle for - -00:21:45.600 --> 00:21:48.159 -3-seater adoption - -00:21:48.159 --> 00:21:50.240 -therefore I've created a language window - -00:21:50.240 --> 00:21:52.960 -package 3-seater length - -00:21:52.960 --> 00:21:54.960 -that takes care of pre-compiling the - -00:21:54.960 --> 00:21:56.320 -grammars the - -00:21:56.320 --> 00:21:59.679 -most common grammars for all three major - -00:21:59.679 --> 00:22:01.600 -platforms - -00:22:01.600 --> 00:22:04.080 -it also takes care of distributing these - -00:22:04.080 --> 00:22:05.360 -binaries - -00:22:05.360 --> 00:22:08.080 -and provides some highlighting queries - -00:22:08.080 --> 00:22:11.440 -for some of the languages - -00:22:11.440 --> 00:22:13.760 -it should be noted that this package - -00:22:13.760 --> 00:22:15.919 -should be treated as a temporary - -00:22:15.919 --> 00:22:19.919 -distribution mechanism only - -00:22:19.919 --> 00:22:22.240 -to help with bootstrapping three-seaters - -00:22:22.240 --> 00:22:24.720 -adoption - -00:22:24.720 --> 00:22:27.760 -the plan is that eventually these files - -00:22:27.760 --> 00:22:29.760 -should be provided by the language major - -00:22:29.760 --> 00:22:32.480 -modes themselves - -00:22:32.480 --> 00:22:35.120 -but in order to do that we need better - -00:22:35.120 --> 00:22:36.320 -tooling - -00:22:36.320 --> 00:22:40.240 -so we're not there yet - -00:22:40.240 --> 00:22:42.559 -since the call already works reasonably - -00:22:42.559 --> 00:22:43.280 -well - -00:22:43.280 --> 00:22:44.640 -there are several areas that would - -00:22:44.640 --> 00:22:46.320 -benefit from the community's - -00:22:46.320 --> 00:22:49.120 -contribution - -00:22:49.120 --> 00:22:51.520 -so three seaters upstream language - -00:22:51.520 --> 00:22:52.640 -prepositories - -00:22:52.640 --> 00:22:54.400 -already contain highlighting queries on - -00:22:54.400 --> 00:22:55.679 -their own - -00:22:55.679 --> 00:22:58.480 -however they are pretty basic and they - -00:22:58.480 --> 00:23:00.480 -may not fit well with existing emax - -00:23:00.480 --> 00:23:02.559 -conventions - -00:23:02.559 --> 00:23:04.320 -therefore the language bundle has its - -00:23:04.320 --> 00:23:07.120 -own set of highlighting queries - -00:23:07.120 --> 00:23:10.559 -this requires maintenance until language - -00:23:10.559 --> 00:23:11.600 -measurements adopt - -00:23:11.600 --> 00:23:13.760 -three sitter and maintain the queries on - -00:23:13.760 --> 00:23:16.640 -their own - -00:23:16.640 --> 00:23:18.480 -the queries are actually quite easy to - -00:23:18.480 --> 00:23:22.000 -write as you've already seen - -00:23:22.000 --> 00:23:24.240 -you just need to be familiar with the - -00:23:24.240 --> 00:23:25.360 -language - -00:23:25.360 --> 00:23:30.000 -familiar enough to come up with sensible - -00:23:30.000 --> 00:23:35.200 -highlighting patterns - -00:23:35.200 --> 00:23:37.600 -and if you are a maintainer of a - -00:23:37.600 --> 00:23:39.679 -language major mode - -00:23:39.679 --> 00:23:42.320 -you may want to consider integrating - -00:23:42.320 --> 00:23:43.360 -tree sitter into - -00:23:43.360 --> 00:23:46.960 -your mode initially maybe as an - -00:23:46.960 --> 00:23:50.080 -optional feature the integration is - -00:23:50.080 --> 00:23:53.279 -actually pretty straightforward - -00:23:53.279 --> 00:23:56.640 -especially for syntax highlighting - -00:23:56.640 --> 00:24:01.520 -or alternatively - -00:24:01.520 --> 00:24:03.760 -you can also try writing a new major - -00:24:03.760 --> 00:24:04.640 -mode - -00:24:04.640 --> 00:24:08.000 -from scratch that relies on tree sitter - -00:24:08.000 --> 00:24:12.559 -from the very beginning - -00:24:12.559 --> 00:24:16.320 -the code for such a major mode is - -00:24:16.320 --> 00:24:19.679 -quite simple for example - -00:24:19.679 --> 00:24:23.200 -this is the proposed - -00:24:23.200 --> 00:24:26.240 -what mode for web assembly - -00:24:26.240 --> 00:24:31.039 -the code is just - -00:24:31.039 --> 00:24:34.559 -like one page of code not - -00:24:34.559 --> 00:24:39.520 -not a lot - -00:24:39.520 --> 00:24:42.720 -you can also try writing new minor modes - -00:24:42.720 --> 00:24:46.559 -or writing integration packages -

My name is Tuấn-Anh. + +00:00:04.400 --> 00:00:07.200 +I've been using Emacs for about 10 years. + +00:00:07.200 --> 00:00:09.280 +Today, I'm going to talk about tree-sitter, + +00:00:09.280 --> 00:00:11.351 +a new Emacs package that allows Emacs + +00:00:11.351 --> 00:00:17.840 +to parse multiple programming languages +in real-time. + +00:00:17.840 --> 00:00:21.840 +So what is the problem statement? + +00:00:21.840 --> 00:00:24.131 +In order to support programming +functionalities + +00:00:24.131 --> 00:00:25.760 +for a particular language, + +00:00:25.760 --> 00:00:27.680 +a text editor needs to have some degree + +00:00:27.680 --> 00:00:29.679 +of language understanding. + +00:00:29.679 --> 00:00:31.840 +Traditionally, text editors have relied + +00:00:31.840 --> 00:00:34.960 +very heavily on regular expressions for +this. + +00:00:34.960 --> 00:00:37.013 +Emacs is no different. + +00:00:37.013 --> 00:00:40.170 +Most language major modes use regular +expressions + +00:00:40.170 --> 00:00:42.960 +for syntax-highlighting, code navigation, + +00:00:42.960 --> 00:00:46.618 +folding, indexing, and so on. + +00:00:46.618 --> 00:00:50.559 +Regular expressions are problematic for +a couple of reasons. + +00:00:50.559 --> 00:00:53.778 +They're slow and inaccurate. + +00:00:53.778 --> 00:00:56.800 +They also make the code hard to read and +write. + +00:00:56.800 --> 00:01:01.199 +Sometimes it's because the regular +expressions themselves are very hairy, + +00:01:01.199 --> 00:01:05.199 +and sometimes because they are just not +powerful enough. + +00:01:05.199 --> 00:01:08.625 +Some helper code is usually needed + +00:01:08.625 --> 00:01:11.200 +to parse more intricate language +features. + +00:01:11.200 --> 00:01:16.159 +That also illustrates the core problem +with regular expressions, + +00:01:16.159 --> 00:01:21.119 +in that they are not powerful enough to +parse programming languages. + +00:01:21.119 --> 00:01:25.040 +An example feature that regular +expressions cannot handle very well + +00:01:25.040 --> 00:01:28.320 +is string interpolation, which is a very +common feature + +00:01:28.320 --> 00:01:31.680 +in many modern programming languages. + +00:01:31.680 --> 00:01:34.079 +It would be much nicer if Emacs somehow + +00:01:34.079 --> 00:01:39.520 +had structural understanding of source +code, like IDEs do. + +00:01:39.520 --> 00:01:41.981 +There have been multiple efforts + +00:01:41.981 --> 00:01:45.280 +to bring this kind of programming +language understanding into Emacs. + +00:01:45.280 --> 00:01:47.119 +There are language-specific parsers + +00:01:47.119 --> 00:01:48.640 +written in Elisp + +00:01:48.640 --> 00:01:50.675 +that can be thought of + +00:01:50.675 --> 00:01:51.989 +as the next logical step +of the glue code + +00:01:51.989 --> 00:01:53.856 +on top of regular expressions, + +00:01:53.856 --> 00:01:57.356 +moving from partial local pattern +recognition + +00:01:57.356 --> 00:01:59.840 +into a full-fledged parser. + +00:01:59.840 --> 00:02:02.023 +The most prominent example of this +approach + +00:02:02.023 --> 00:02:06.479 +is probably the famous js2-mode. + +00:02:06.479 --> 00:02:10.080 +However, this approach has several issues. + +00:02:10.080 --> 00:02:12.606 +Parsing is computationally expensive, + +00:02:12.606 --> 00:02:16.800 +and Emacs Lisp is not good at that kind +of stuff. + +00:02:16.800 --> 00:02:19.156 +Furthermore, maintenance is very +troublesome. + +00:02:19.156 --> 00:02:22.160 +In order to work on these parsers, + +00:02:22.160 --> 00:02:24.239 +first, you have to know Elisp +well enough, + +00:02:24.239 --> 00:02:26.606 +and then you have to be comfortable with + +00:02:26.606 --> 00:02:29.739 +writing a recursive descending parser, + +00:02:29.739 --> 00:02:34.000 +while constantly keeping up with changes +to the language itself, + +00:02:34.000 --> 00:02:36.356 +which can be evolving very quickly, + +00:02:36.356 --> 00:02:39.360 +like Javascript, for example. + +00:02:39.360 --> 00:02:42.373 +Together, these constraints +significantly reduce + +00:02:42.373 --> 00:02:45.680 +the pool of potential maintainers. + +00:02:45.680 --> 00:02:47.760 +The biggest issue, though, in my opinion, + +00:02:47.760 --> 00:02:52.139 +is lack of the set of generic and +reusable APIs. + +00:02:52.139 --> 00:02:54.319 +This makes them very hard to use + +00:02:54.319 --> 00:02:55.920 +for minor modes that want to deal with + +00:02:55.920 --> 00:02:59.920 +cross-cutting concerns across multiple +languages. + +00:02:59.920 --> 00:03:01.760 +The other approach which has been + +00:03:01.760 --> 00:03:04.319 +gaining a lot of momentum +in recent years + +00:03:04.319 --> 00:03:06.560 +is externalizing language understanding + +00:03:06.560 --> 00:03:08.159 +to another process, + +00:03:08.159 --> 00:03:12.239 +also known as language server protocol. + +00:03:12.239 --> 00:03:16.560 +This second approach is actually a very +interesting one. + +00:03:16.560 --> 00:03:18.400 +By decoupling language understanding + +00:03:18.400 --> 00:03:21.280 +from the editing facility itself, + +00:03:21.280 --> 00:03:25.120 +the LSP servers can attract a lot more +contributors, + +00:03:25.120 --> 00:03:27.189 +which makes maintenance easier. + +00:03:27.189 --> 00:03:32.400 +However, they also have several issues +of their own. + +00:03:32.400 --> 00:03:34.089 +Being a separate process, + +00:03:34.089 --> 00:03:37.073 +they are usually more +resource-intensive, + +00:03:37.073 --> 00:03:39.920 +and depending on the language, + +00:03:39.920 --> 00:03:42.159 +the LSP server itself can bring with it + +00:03:42.159 --> 00:03:44.640 +a host of additional dependencies + +00:03:44.640 --> 00:03:50.640 +external to Emacs, which may be messy to +install and manage. + +00:03:50.640 --> 00:03:55.120 +Furthermore, JSON over RPC has pretty +high latency. + +00:03:55.120 --> 00:03:57.840 +For one-off tasks like jumping to source + +00:03:57.840 --> 00:04:00.879 +or on-demand completion, it's great. + +00:04:00.879 --> 00:04:03.040 +But for things like code highlighting, + +00:04:03.040 --> 00:04:06.000 +the latency is just too much. + +00:04:06.000 --> 00:04:08.319 +I was using Rust and I was following the + +00:04:08.319 --> 00:04:11.760 +community effort to improve its +IDE support, + +00:04:11.760 --> 00:04:15.760 +hoping to integrate some of that into +Emacs itself. + +00:04:15.760 --> 00:04:19.759 +Then I heard someone from the community +mention tree-sitter, + +00:04:19.759 --> 00:04:23.360 +and I decided to check it out. + +00:04:23.360 --> 00:04:28.720 +Basically, tree-sitter is an incremental +parsing library and a parser generator. + +00:04:28.720 --> 00:04:33.040 +It was introduced by the Atom editor in +2018. + +00:04:33.040 --> 00:04:35.923 +Besides Atom, it is also being +integrated + +00:04:35.923 --> 00:04:37.623 +into the NeoVim editor, + +00:04:37.623 --> 00:04:41.040 +and Github is using it to power + +00:04:41.040 --> 00:04:42.423 +their source code analysis + +00:04:42.423 --> 00:04:45.840 +and navigation features. + +00:04:45.840 --> 00:04:48.639 +It is written in C and can be compiled + +00:04:48.639 --> 00:04:50.623 +for all major platforms. + +00:04:50.623 --> 00:04:53.120 +It can even be compiled + +00:04:53.120 --> 00:04:55.323 +to web assembly to run on the web. + +00:04:55.323 --> 00:05:00.800 +That's how Github is using it +on their website. + +00:05:00.800 --> 00:05:05.840 +So why is tree-sitter an interesting +solution to this problem? + +00:05:05.840 --> 00:05:10.000 +There are multiple features that make it +an attractive option. + +00:05:10.000 --> 00:05:11.839 +It is designed to be fast. + +00:05:11.839 --> 00:05:13.680 +By being incremental, + +00:05:13.680 --> 00:05:15.680 +the initial parse of a typical big file + +00:05:15.680 --> 00:05:18.160 +can take tens of milliseconds, + +00:05:18.160 --> 00:05:20.240 +while subsequent incremental processes + +00:05:20.240 --> 00:05:22.560 +are sub-millisecond. + +00:05:22.560 --> 00:05:26.240 +It achieves this by using +structural sharing, + +00:05:26.240 --> 00:05:29.360 +meaning replacing only affected nodes + +00:05:29.360 --> 00:05:32.960 +in the old tree when it needs to. + +00:05:32.960 --> 00:05:37.120 +Also, unlike LSP, being in +the same process, + +00:05:37.120 --> 00:05:40.639 +it has much lower latency. + +00:05:40.639 --> 00:05:44.960 +Secondly, it provides a uniform +programming interface. + +00:05:44.960 --> 00:05:47.039 +The same data structures and functions + +00:05:47.039 --> 00:05:50.400 +work on parse trees of different +languages. + +00:05:50.400 --> 00:05:52.160 +Syntax nodes of different languages + +00:05:52.160 --> 00:05:54.160 +differ only by their types + +00:05:54.160 --> 00:05:55.723 +and their possible child nodes. + +00:05:55.723 --> 00:06:02.240 +This is a big advantage over +language-specific parsers. + +00:06:02.240 --> 00:06:06.880 +Thirdly, it's written in self-contained +embeddable C. + +00:06:06.880 --> 00:06:11.723 +As I mentioned previously, it can even +be compiled to webassembly. + +00:06:11.723 --> 00:06:16.106 +This makes integrating it into various +editors quite easy + +00:06:16.106 --> 00:06:22.880 +without having to install any external +dependencies. + +00:06:22.880 --> 00:06:25.503 +One thing that is not mentioned here + +00:06:25.503 --> 00:06:28.000 +is that being a parser generator, + +00:06:28.000 --> 00:06:31.039 +its grammars are declarative. + +00:06:31.039 --> 00:06:34.880 +Together with being editor-independent, + +00:06:34.880 --> 00:06:39.139 +this makes the pool of potential +contributors much larger. + +00:06:39.139 --> 00:06:45.520 +So I was convinced that tree-sitter is a +good fit for Emacs. + +00:06:45.520 --> 00:06:48.000 +Last year, I started writing the bindings + +00:06:48.000 --> 00:06:53.280 +using dynamic module support introduced +in Emacs 25. + +00:06:53.280 --> 00:06:58.479 +Dynamic module means there is +platform-specific native code involved, + +00:06:58.479 --> 00:07:00.560 +but since there are pre-compiled binaries + +00:07:00.560 --> 00:07:02.880 +for the three major platforms, + +00:07:02.880 --> 00:07:04.706 +it should work in most places. + +00:07:04.706 --> 00:07:09.440 +Currently, the core functionalities are +in a pretty good shape. + +00:07:09.440 --> 00:07:12.560 +Syntax highlighting is working nicely. + +00:07:12.560 --> 00:07:16.080 +The whole thing is split into three +packages. + +00:07:16.080 --> 00:07:20.319 +tree-sitter is the main package that +other packages should depend on. + +00:07:20.319 --> 00:07:22.800 +tree-sitter-langs is the language bundle + +00:07:22.800 --> 00:07:24.000 +that includes support + +00:07:24.000 --> 00:07:27.199 +for most common languages. + +00:07:27.199 --> 00:07:32.160 +And finally, the core APIs are in the +package tsc, + +00:07:32.160 --> 00:07:36.160 +which stands for tree-sitter-core. + +00:07:36.160 --> 00:07:38.800 +It is the implicit dependency of the + +00:07:38.800 --> 00:07:43.520 +tree-sitter package. + +00:07:43.520 --> 00:07:47.520 +The main package includes the minor mode +tree-sitter-mode. + +00:07:47.520 --> 00:07:52.560 +This provides the base for other major +or minor modes to build on. + +00:07:52.560 --> 00:07:54.839 +Using Emacs's change tracking hooks, + +00:07:54.839 --> 00:07:57.073 +it enables incremental parsing + +00:07:57.073 --> 00:08:00.800 +and provides a syntax tree that is +always up to date + +00:08:00.800 --> 00:08:04.080 +after any edits in a buffer. + +00:08:04.080 --> 00:08:06.223 +There is also a basic debug mode + +00:08:06.223 --> 00:08:10.080 +that shows the parse tree in +another buffer. + +00:08:10.080 --> 00:08:13.360 +Here is a quick demo. + +00:08:13.360 --> 00:08:15.673 +Here I'm in an empty Python buffer + +00:08:15.673 --> 00:08:17.520 +with tree-sitter enabled. + +00:08:17.520 --> 00:08:19.440 +I'm going to turn on the debug mode to + +00:08:19.440 --> 00:08:26.560 +see the parse tree. + +00:08:26.560 --> 00:08:28.106 +Since the buffer is empty, + +00:08:28.106 --> 00:08:30.423 +there is only one node in the +syntax tree: + +00:08:30.423 --> 00:08:33.279 +the top-level module node. + +00:08:33.279 --> 00:09:11.040 +Let's try typing some code. + +00:09:11.040 --> 00:09:14.640 +As you can see, as I type into the +Python buffer, + +00:09:14.640 --> 00:09:19.120 +the syntax tree updates in real time. + +00:09:19.120 --> 00:09:22.039 +The other minor mode included in the +main package + +00:09:22.039 --> 00:09:24.389 +is tree-sitter-hl-mode. + +00:09:24.389 --> 00:09:26.349 +It overrides font-lock mode + +00:09:26.349 --> 00:09:28.480 +and provides its own set of phases + +00:09:28.480 --> 00:09:30.139 +and customization options + +00:09:30.139 --> 00:09:32.800 +It is query-driven. + +00:09:32.800 --> 00:09:36.240 +That means instead of regular +expressions, + +00:09:36.240 --> 00:09:39.518 +it uses a Lisp-like query language + +00:09:39.518 --> 00:09:40.320 +to map syntax nodes + +00:09:40.320 --> 00:09:41.923 +to highlighting phrases. + +00:09:41.923 --> 00:09:45.760 +I'm going to open a python file with +small snippets + +00:09:45.760 --> 00:09:54.320 +that showcase syntax highlighting. + +00:09:54.320 --> 00:09:55.920 +So this is the default highlighting + +00:09:55.920 --> 00:10:00.880 +provided by python-mode. + +00:10:00.880 --> 00:10:04.640 +This is the highlighting enabled +by tree-sitter. + +00:10:04.640 --> 00:10:07.680 +As you can see, string interpolation + +00:10:07.680 --> 00:10:11.680 +and decorators are highlighted correctly. + +00:10:11.680 --> 00:10:17.440 +Function calls are also highlighted. + +00:10:17.440 --> 00:10:21.839 +You can also note that +property accessors + +00:10:21.839 --> 00:10:27.440 +and property assignments are highlighted +differently. + +00:10:27.440 --> 00:10:29.360 +What I like the most about this is that + +00:10:29.360 --> 00:10:32.640 +new bindings are consistently +highlighted. + +00:10:32.640 --> 00:10:36.320 +This included local variables, + +00:10:36.320 --> 00:10:45.760 +function parameters, and property +mutations. + +00:10:45.760 --> 00:10:48.000 +Before going through the tree queries + +00:10:48.000 --> 00:10:49.279 +and the syntax highlighting + +00:10:49.279 --> 00:10:51.680 +customization options, + +00:10:51.680 --> 00:10:53.339 +let's take a brief look at + +00:10:53.339 --> 00:10:55.040 +the core data structures and functions + +00:10:55.040 --> 00:10:58.079 +that tree-sitter provides. + +00:10:58.079 --> 00:11:00.743 +So parsing is done with the help of + +00:11:00.743 --> 00:11:02.240 +a generic parser object. + +00:11:02.240 --> 00:11:04.160 +A single parser object can be used to + +00:11:04.160 --> 00:11:06.000 +parse different languages + +00:11:06.000 --> 00:11:09.279 +by sending different language objects to +it. + +00:11:09.279 --> 00:11:10.880 +The language objects themselves are + +00:11:10.880 --> 00:11:14.079 +loaded from shared libraries. + +00:11:14.079 --> 00:11:16.079 +Since tree-sitter-mmode already handles + +00:11:16.079 --> 00:11:17.360 +the parsing part, + +00:11:17.360 --> 00:11:19.440 +we will instead focus on the functions + +00:11:19.440 --> 00:11:20.800 +that inspect nodes, + +00:11:20.800 --> 00:11:25.279 +and in the resulting path tree, + +00:11:25.279 --> 00:11:27.030 +we can ask tree-sitter what is + +00:11:27.030 --> 00:11:44.240 +the syntax node at point. + +00:11:44.240 --> 00:11:48.480 +This is an opaque object, so this is not +very useful. + +00:11:48.480 --> 00:12:03.760 +We can instead ask what is its type. + +00:12:03.760 --> 00:12:08.959 +So its type is the symbol comparison +operator. + +00:12:08.959 --> 00:12:11.600 +In tree-sitter, there are two kinds of nodes, + +00:12:11.600 --> 00:12:13.680 +anonymous nodes and named nodes. + +00:12:13.680 --> 00:12:17.040 +Anonymous nodes correspond to simple +grammar elements + +00:12:17.040 --> 00:12:21.279 +like keywords, operators, punctuations, +and so on. + +00:12:21.279 --> 00:12:24.656 +Name nodes, on the other hand, are +grammar elements + +00:12:24.656 --> 00:12:26.639 +that are interesting enough +on their own + +00:12:26.639 --> 00:12:30.029 +to have a name, like an identifier, + +00:12:30.029 --> 00:12:35.440 +an expression, or a function definition. + +00:12:35.440 --> 00:12:37.323 +Name node types are symbols, + +00:12:37.323 --> 00:12:42.639 +while anonymous node types are strings. + +00:12:42.639 --> 00:12:49.760 +For example, if we are on this +comparison operator, + +00:12:49.760 --> 00:12:55.920 +the node type should be a string. + +00:12:55.920 --> 00:12:58.959 +We can also get other information about +the node. + +00:12:58.959 --> 00:13:09.680 +For example: what is this text, + +00:13:09.680 --> 00:13:20.800 +or where it is in the buffer, + +00:13:20.800 --> 00:13:43.199 +or what is its parent. + +00:13:43.199 --> 00:13:46.106 +There are many other APIs to query + +00:13:46.106 --> 00:13:52.639 +our node's properties. + +00:13:52.639 --> 00:13:54.234 +tree-sitter allows searching + +00:13:54.234 --> 00:13:58.240 +for structural patterns +within a parse tree. + +00:13:58.240 --> 00:14:01.440 +It does so through a Lisp-like language. + +00:14:01.440 --> 00:14:04.639 +This language supports matching +by node types, + +00:14:04.639 --> 00:14:07.760 +field names, and predicates. + +00:14:07.760 --> 00:14:12.639 +It also allows capturing nodes for +further processing. + +00:14:12.639 --> 00:14:37.680 +Let's try to see some examples. + +00:14:37.680 --> 00:14:40.206 +So in this very simple query, + +00:14:40.206 --> 00:14:49.040 +we just try to highlight all the +identifiers in the buffer. + +00:14:49.040 --> 00:14:53.120 +This s side tells tree-sitter +to capture a node. + +00:14:53.120 --> 00:14:55.507 +In the context of the query builder, + +00:14:55.507 --> 00:14:57.360 +it's not very important, + +00:14:57.360 --> 00:14:59.706 +but in normal highlighting query, + +00:14:59.706 --> 00:15:01.760 +this will determine + +00:15:01.760 --> 00:15:06.639 +the face used to highlight the note. + +00:15:06.639 --> 00:15:08.256 +Suppose we want to capture + +00:15:08.256 --> 00:15:10.320 +all the function names, + +00:15:10.320 --> 00:15:13.519 +instead of just any identifier. + +00:15:13.519 --> 00:15:29.440 +You can improve the query like this. + +00:15:29.440 --> 00:15:32.639 +This will highlight the whole definition. + +00:15:32.639 --> 00:15:36.399 +But we only want to capture +the function name, + +00:15:36.399 --> 00:15:41.054 +which means the identifier here. + +00:15:41.054 --> 00:15:49.600 +So we move the capture to after the +identifier node. + +00:15:49.600 --> 00:15:52.959 +If we want to capture the +class names as well, + +00:15:52.959 --> 00:16:10.079 +we just add another pattern. + +00:16:10.079 --> 00:16:20.320 +Let's look at a more practical example. + +00:16:20.320 --> 00:16:23.468 +Here we can see that +single-quoted strings + +00:16:23.468 --> 00:16:27.279 +and double-quoted strings are +highlighted the same. + +00:16:27.279 --> 00:16:30.399 +But in some places, + +00:16:30.399 --> 00:16:33.440 +because of some coding conventions, + +00:16:33.440 --> 00:16:36.373 +it may be desirable to highlight them +differently. + +00:16:36.373 --> 00:16:39.073 +For example, if the string is +single-quoted, + +00:16:39.073 --> 00:16:44.399 +we may want to highlight it as a +constant. + +00:16:44.399 --> 00:16:46.160 +Let's try to see whether we can + +00:16:46.160 --> 00:16:56.240 +distinguish these two cases. + +00:16:56.240 --> 00:17:00.639 +So here we get all the strings. + +00:17:00.639 --> 00:17:04.079 +If we want to see if it's single quotes + +00:17:04.079 --> 00:17:08.799 +or double quote strings, + +00:17:08.799 --> 00:17:13.436 +we can try looking at the first +character of the string-- + +00:17:13.436 --> 00:17:16.720 +I mean the first character of the node-- + +00:17:16.720 --> 00:17:33.600 +to check whether it's a single quote or +a double quote. + +00:17:33.600 --> 00:17:38.920 +So for that, we use tree-sitter's +support for predicates. + +00:17:38.920 --> 00:17:43.360 +In this case, we use a match predicate + +00:17:43.360 --> 00:17:47.339 +to check whether the string-- +whether the node starts + +00:17:47.339 --> 00:17:49.556 +with a single quote. + +00:17:49.556 --> 00:17:51.280 +And with this pattern, + +00:17:51.280 --> 00:18:00.400 +we only capture the single-quotes +strings. + +00:18:00.400 --> 00:18:03.760 +Let's try to give it a different face. + +00:18:03.760 --> 00:18:13.039 +So we copy the pattern, + +00:18:13.039 --> 00:18:25.120 +and we add this pattern for Python only. + +00:18:25.120 --> 00:18:31.440 +But we also want to give the capture +a different name. + +00:18:31.440 --> 00:18:46.559 +Let's say we want to highlight it +as a keyword. + +00:18:46.559 --> 00:19:06.320 +And now, if we refresh the buffer, + +00:19:06.320 --> 00:19:08.523 +we see that single quote strings + +00:19:08.523 --> 00:19:14.400 +are highlighted as keywords. + +00:19:14.400 --> 00:19:15.751 +The highlighting patterns + +00:19:15.751 --> 00:19:19.200 +can also be set for a single project + +00:19:19.200 --> 00:19:23.440 +using directory-local variables. + +00:19:23.440 --> 00:19:35.760 +For example, let's take a look at +Emacs's source code. + +00:19:35.760 --> 00:19:41.123 +So in Emacs's C source, +there are a lot of uses + +00:19:41.123 --> 00:19:43.760 +of these different macros + +00:19:43.760 --> 00:19:47.679 +to define functions, + +00:19:47.679 --> 00:19:53.256 +and you can see this is actually +the function name, + +00:19:53.256 --> 00:19:56.373 +but it's highlighted as the string. + +00:19:56.373 --> 00:20:03.679 +So what we want is to somehow +recognize this pattern + +00:20:03.679 --> 00:20:07.600 +and highlight it. + +00:20:07.600 --> 00:20:11.280 +Highlight this part + +00:20:11.280 --> 00:20:14.559 +with the function face instead. + +00:20:14.559 --> 00:20:17.679 +In order to do that, + +00:20:17.679 --> 00:20:31.760 +we put a pattern in this project's +directory-local settings file. + +00:20:31.760 --> 00:20:40.159 +So we can put this button in +the C mode section. + +00:20:40.159 --> 00:20:48.000 +And now, if we enable tree-sitter, + +00:20:48.000 --> 00:20:50.480 +you can see that this is highlighted + +00:20:53.200 --> 00:20:55.056 +as a normal function definition. + +00:20:55.056 --> 00:21:01.200 +So this is the function face +like we wanted. + +00:21:01.200 --> 00:21:07.200 +The pattern for this is +actually pretty simple. + +00:21:07.200 --> 00:21:12.373 +It's only this part. + +00:21:12.373 --> 00:21:16.456 +So if it's a function call + +00:21:16.456 --> 00:21:19.679 +where the name of the function is +defun, + +00:21:19.679 --> 00:21:24.240 +then we highlight the defun as a +keyword, + +00:21:24.240 --> 00:21:26.923 +and then the first string element, + +00:21:26.923 --> 00:21:35.360 +we highlight it as a function name. + +00:21:35.360 --> 00:21:39.280 +Since the language objects are actually +native code, + +00:21:39.280 --> 00:21:41.459 +they have to be compiled +for each platform + +00:21:41.459 --> 00:21:43.440 +that we want to support. + +00:21:43.440 --> 00:21:48.159 +This will become a big obstacle for +tree-sitter adoption. + +00:21:48.159 --> 00:21:52.960 +Therefore, I've created a language bundle +package, tree-sitter-langs, + +00:21:52.960 --> 00:21:55.773 +that takes care of pre-compiling the +grammars, + +00:21:55.773 --> 00:22:01.600 +the most common grammars for all three +major platforms. + +00:22:01.600 --> 00:22:05.360 +It also takes care of distributing +these binaries + +00:22:05.360 --> 00:22:08.080 +and provides some highlighting queries + +00:22:08.080 --> 00:22:11.440 +for some of the languages. + +00:22:11.440 --> 00:22:13.760 +It should be noted that this package + +00:22:13.760 --> 00:22:19.919 +should be treated as a temporary +distribution mechanism only, + +00:22:19.919 --> 00:22:24.720 +to help with bootstrapping +tree-sitter adoption. + +00:22:24.720 --> 00:22:27.760 +The plan is that eventually these files + +00:22:27.760 --> 00:22:29.156 +should be provided by + +00:22:29.156 --> 00:22:32.480 +the language major modes themselves. + +00:22:32.480 --> 00:22:36.320 +But in order to do that, we need better +tooling, + +00:22:36.320 --> 00:22:40.240 +so we're not there yet. + +00:22:40.240 --> 00:22:43.280 +Since the core already works +reasonably well, + +00:22:43.280 --> 00:22:45.289 +there are several areas +that would benefit + +00:22:45.289 --> 00:22:49.120 +from the community's contribution. + +00:22:49.120 --> 00:22:52.640 +So tree-sitter's upstream language +repositories + +00:22:52.640 --> 00:22:55.679 +already contain highlighting queries on +their own. + +00:22:55.679 --> 00:22:57.573 +However, they are pretty basic, + +00:22:57.573 --> 00:23:02.559 +and they may not fit well with existing +Emacs conventions. + +00:23:02.559 --> 00:23:07.120 +Therefore, the language bundle has its +own set of highlighting queries. + +00:23:07.120 --> 00:23:12.556 +This requires maintenance until language +major modes adopt tree-sitter + +00:23:12.556 --> 00:23:16.640 +and maintain the queries on their own. + +00:23:16.640 --> 00:23:19.056 +The queries are actually +quite easy to write, + +00:23:19.056 --> 00:23:22.000 +as you've already seen. + +00:23:22.000 --> 00:23:25.360 +You just need to be familiar +with the language, + +00:23:25.360 --> 00:23:35.200 +familiar enough to come up with sensible +highlighting patterns. + +00:23:35.200 --> 00:23:39.679 +And if you are a maintainer of a +language major mode, + +00:23:39.679 --> 00:23:44.189 +you may want to consider integrating +tree-sitter into your mode, + +00:23:44.189 --> 00:23:48.573 +initially maybe as an optional feature. + +00:23:48.573 --> 00:23:53.279 +The integration is actually pretty +straightforward, + +00:23:53.279 --> 00:23:56.640 +especially for syntax highlighting. + +00:23:56.640 --> 00:24:01.520 +Or alternatively, + +00:24:01.520 --> 00:24:05.760 +you can also try writing a new major +mode from scratch + +00:24:05.760 --> 00:24:08.000 +that relies on tree-sitter + +00:24:08.000 --> 00:24:12.559 +from the very beginning. + +00:24:12.559 --> 00:24:17.523 +The code for such a major mode is +quite simple. + +00:24:17.523 --> 00:24:23.200 +For example, this is the proposed + +00:24:23.200 --> 00:24:26.240 +wat-mode for web assembly. + +00:24:26.240 --> 00:24:39.520 +The code is just one page of code, +not a lot. + +00:24:39.520 --> 00:24:42.720 +You can also try writing new minor modes + +00:24:42.720 --> 00:24:46.559 +or writing integration packages. + +00:24:46.559 --> 00:24:50.880 +For example, a lot of packages + +00:24:50.880 --> 00:24:54.559 +may benefit from tree-sitter integration, + +00:24:54.559 --> 00:25:02.960 +but no one has written +the integration yet. + +00:25:02.960 --> 00:25:04.836 +If you are interested in tree-sitter, + +00:25:04.836 --> 00:25:08.023 +you can use these links to learn more +about it. + +00:25:08.023 --> 00:25:11.440 +I think that's it for me today. + +00:25:11.440 --> 00:25:18.159 +I'm happy to answer any questions. diff --git

in a structured format for example in - -00:01:23.520 --> 00:01:24.560 -json - -00:01:24.560 --> 00:01:26.640 -that might even be if your job is not - -00:01:26.640 --> 00:01:28.560 -programming per se - -00:01:28.560 --> 00:01:30.400 -and reading through such a bigger chunk - -00:01:30.400 --> 00:01:33.119 -of json can be non-trivial however - -00:01:33.119 --> 00:01:36.479 -while just reading and understanding it - -00:01:36.479 --> 00:01:39.119 -will be essential to getting your job - -00:01:39.119 --> 00:01:40.320 -done - -00:01:40.320 --> 00:01:43.680 -so let's quickly check out an example - -00:01:43.680 --> 00:01:47.200 -json file this is from the github api - -00:01:47.200 --> 00:01:50.560 -where which is a request sorry the - -00:01:50.560 --> 00:01:53.119 -response to a request for a specific - -00:01:53.119 --> 00:01:55.280 -issue on the github api so let's - -00:01:55.280 --> 00:01:58.799 -quickly check that one out - -00:01:58.799 --> 00:02:01.280 -okay so here it is open and we can - -00:02:01.280 --> 00:02:03.280 -already see that there is lots of stuff - -00:02:03.280 --> 00:02:05.439 -going on here - -00:02:05.439 --> 00:02:08.319 -it's uh 200 lines it's not going to be - -00:02:08.319 --> 00:02:10.319 -very easy just just to find out what are - -00:02:10.319 --> 00:02:12.160 -the top level things in here what are - -00:02:12.160 --> 00:02:13.920 -the top level attributes of course I can - -00:02:13.920 --> 00:02:14.560 -do this - -00:02:14.560 --> 00:02:16.480 -and maybe it would by hand but that - -00:02:16.480 --> 00:02:17.840 -doesn't scale - -00:02:17.840 --> 00:02:20.560 -I can use cool Emacs facilities like the - -00:02:20.560 --> 00:02:22.560 -height show mode and try to - -00:02:22.560 --> 00:02:24.720 -fold all the things that are top level - -00:02:24.720 --> 00:02:27.200 -but that also doesn't really scale - -00:02:27.200 --> 00:02:29.760 -there must be a better way and of course - -00:02:29.760 --> 00:02:32.000 -there is there is prior art - -00:02:32.000 --> 00:02:34.959 -there is a tool called jq I'm going to - -00:02:34.959 --> 00:02:36.080 -quote the usp - -00:02:36.080 --> 00:02:39.120 -from their website jq is like - -00:02:39.120 --> 00:02:42.959 -sed said for json data you can use it to - -00:02:42.959 --> 00:02:44.720 -slice and filter and map - -00:02:44.720 --> 00:02:46.720 -and transform structured data with the - -00:02:46.720 --> 00:02:47.840 -same ease that - -00:02:47.840 --> 00:02:51.519 -z awk grep and friends let you play with - -00:02:51.519 --> 00:02:54.000 -text - -00:02:54.000 --> 00:02:56.160 -let me give you a quick demonstration of - -00:02:56.160 --> 00:02:57.519 -it by the way - -00:02:57.519 --> 00:02:59.680 -it's written in portable c it has zero - -00:02:59.680 --> 00:03:01.920 -runtime dependency so it's very easy - -00:03:01.920 --> 00:03:04.959 -to get started with it and use it on - -00:03:04.959 --> 00:03:09.040 -pretty much any unix-based - -00:03:09.040 --> 00:03:12.800 -computer sorry no linux based computer - -00:03:12.800 --> 00:03:16.159 -apologies okay so let's explore a - -00:03:16.159 --> 00:03:19.599 -json file with it it's a command line - -00:03:19.599 --> 00:03:21.120 -tool and it has a very - -00:03:21.120 --> 00:03:24.640 -simple command line syntax so you - -00:03:24.640 --> 00:03:26.799 -call the binary and then you give it a - -00:03:26.799 --> 00:03:27.840 -query - -00:03:27.840 --> 00:03:31.680 -and a file and then we'll return - -00:03:31.680 --> 00:03:33.840 -its answer so for example if I want the - -00:03:33.840 --> 00:03:35.440 -top level keys - -00:03:35.440 --> 00:03:38.319 -I will just say jq keys the file and it - -00:03:38.319 --> 00:03:39.840 -will return the keys - -00:03:39.840 --> 00:03:42.319 -simple as that so let's check this out - -00:03:42.319 --> 00:03:43.519 -in a real - -00:03:43.519 --> 00:03:46.879 -shell here I am in eshel - -00:03:46.879 --> 00:03:50.080 -let's run jq keys on the github - -00:03:50.080 --> 00:03:53.200 -issue comment and we can see - -00:03:53.200 --> 00:03:56.959 -that we have actually received a list - -00:03:56.959 --> 00:04:00.000 -back here with the top level - -00:04:00.000 --> 00:04:02.000 -things okay so this issue it looks very - -00:04:02.000 --> 00:04:04.319 -very interesting so let's uh ask it to - -00:04:04.319 --> 00:04:06.239 -give me more information on this - -00:04:06.239 --> 00:04:10.080 -issue then it's hairy again that's a lot - -00:04:10.080 --> 00:04:11.360 -of stuff - -00:04:11.360 --> 00:04:14.319 -I mean lucky for for us we are in Emacs - -00:04:14.319 --> 00:04:17.759 -here so we can use nice shortcuts we can - -00:04:17.759 --> 00:04:21.040 -copy this we go can go in here just - -00:04:21.040 --> 00:04:22.000 -select that - -00:04:22.000 --> 00:04:24.400 -get that out or something like this but - -00:04:24.400 --> 00:04:25.600 -still - -00:04:25.600 --> 00:04:28.320 -this is not really it's not really the - -00:04:28.320 --> 00:04:29.600 -best way - -00:04:29.600 --> 00:04:34.080 -to do that right it gets kind of tedious - -00:04:34.080 --> 00:04:36.639 -at this point the output can be - -00:04:36.639 --> 00:04:37.680 -humongous - -00:04:37.680 --> 00:04:39.360 -the shell is not really the best place - -00:04:39.360 --> 00:04:42.479 -to read through such big output I mean e - -00:04:42.479 --> 00:04:43.600 -shell is - -00:04:43.600 --> 00:04:45.440 -probably one of the better shells for - -00:04:45.440 --> 00:04:47.440 -this because it's just a regular Emacs - -00:04:47.440 --> 00:04:48.560 -buffer but still - -00:04:48.560 --> 00:04:51.199 -it's not really the best tool and I need - -00:04:51.199 --> 00:04:52.720 -to repeat the command - -00:04:52.720 --> 00:04:55.280 -all the time until I finally build the - -00:04:55.280 --> 00:04:56.000 -right query - -00:04:56.000 --> 00:04:59.120 -and all the time I use I lose my - -00:04:59.120 --> 00:05:02.080 -focus I lose what I'm currently looking - -00:05:02.080 --> 00:05:02.800 -at - -00:05:02.800 --> 00:05:06.080 -I'm seeing the new result it would be so - -00:05:06.080 --> 00:05:08.160 -much nicer to have live feedback - -00:05:08.160 --> 00:05:10.080 -and when working with Emacs we're quite - -00:05:10.080 --> 00:05:11.600 -used to that so there should be an - -00:05:11.600 --> 00:05:12.320 -option - -00:05:12.320 --> 00:05:15.120 -and of course there is it's Emacs right - -00:05:15.120 --> 00:05:17.759 -so you can do anything - -00:05:17.759 --> 00:05:20.880 -there is various good tools for - -00:05:20.880 --> 00:05:22.960 -completion in Emacs - -00:05:22.960 --> 00:05:26.000 -I used ivy for this - -00:05:26.000 --> 00:05:29.039 -I'm going to code the usp for ivy - -00:05:29.039 --> 00:05:31.840 -iv is a generic completion mechanism for - -00:05:31.840 --> 00:05:32.639 -Emacs - -00:05:32.639 --> 00:05:34.639 -while it operates similarly to other - -00:05:34.639 --> 00:05:35.919 -completion schemes - -00:05:35.919 --> 00:05:38.960 -such as icomplete mode iv aims to be - -00:05:38.960 --> 00:05:40.400 -more efficient smaller - -00:05:40.400 --> 00:05:43.120 -simpler and smoother to use yet highly - -00:05:43.120 --> 00:05:45.199 -customizable - -00:05:45.199 --> 00:05:47.840 -and that's true one of the cool things - -00:05:47.840 --> 00:05:49.440 -of iv - -00:05:49.440 --> 00:05:52.479 -compared to other completion mechanisms - -00:05:52.479 --> 00:05:54.320 -in Emacs - -00:05:54.320 --> 00:05:58.160 -is that it can be used on dynamic - -00:05:58.160 --> 00:06:01.600 -data so usually completion works on a - -00:06:01.600 --> 00:06:03.520 -static input for example you're in a - -00:06:03.520 --> 00:06:05.360 -buffer a text buffer - -00:06:05.360 --> 00:06:08.800 -and you use I search maybe with idle - -00:06:08.800 --> 00:06:09.600 -mode - -00:06:09.600 --> 00:06:12.400 -and you find your results that's all - -00:06:12.400 --> 00:06:13.360 -nice - -00:06:13.360 --> 00:06:16.960 -however if I - -00:06:16.960 --> 00:06:19.840 -want to search on dynamic data that - -00:06:19.840 --> 00:06:20.720 -doesn't work - -00:06:20.720 --> 00:06:23.759 -so whenever I type in my query - -00:06:23.759 --> 00:06:27.039 -for jq I actually need to call the jq - -00:06:27.039 --> 00:06:28.000 -binary - -00:06:28.000 --> 00:06:30.160 -and it will give a different result set - -00:06:30.160 --> 00:06:32.840 -back so it's a really - -00:06:32.840 --> 00:06:36.319 -dynamic mechanism that we need here it's - -00:06:36.319 --> 00:06:38.240 -much more like a search engine - -00:06:38.240 --> 00:06:41.440 -and ivy luckily has something built in - -00:06:41.440 --> 00:06:42.560 -and it's called - -00:06:42.560 --> 00:06:46.000 -console so I used council and jq - -00:06:46.000 --> 00:06:48.160 -and combined them and build a new - -00:06:48.160 --> 00:06:49.199 -package - -00:06:49.199 --> 00:06:52.960 -with which we can use Emacs and jq - -00:06:52.960 --> 00:06:56.000 -to have live feedback - -00:06:56.000 --> 00:06:58.800 -it's very easy to use so you just call - -00:06:58.800 --> 00:06:59.840 -console.jq - -00:06:59.840 --> 00:07:02.800 -on a buffer containing json for example - -00:07:02.800 --> 00:07:04.319 -the one we have here - -00:07:04.319 --> 00:07:07.280 -let's call console.jq on it and we - -00:07:07.280 --> 00:07:08.319 -already - -00:07:08.319 --> 00:07:11.280 -get a default query the dot query which - -00:07:11.280 --> 00:07:13.039 -just gives us - -00:07:13.039 --> 00:07:16.080 -the same file but now we can change it - -00:07:16.080 --> 00:07:17.280 -and for example - -00:07:17.280 --> 00:07:19.039 -find all the keys in here and then we - -00:07:19.039 --> 00:07:21.039 -see I had this issue this was the one - -00:07:21.039 --> 00:07:22.800 -that we were interested in - -00:07:22.800 --> 00:07:24.639 -so let's find more information on the - -00:07:24.639 --> 00:07:26.479 -issue what - -00:07:26.479 --> 00:07:28.800 -keys does it have actually have uh it - -00:07:28.800 --> 00:07:31.680 -has assignees that that interests me - -00:07:31.680 --> 00:07:34.800 -so let's check out the assignees in here - -00:07:34.800 --> 00:07:37.039 -there's two of them but I'm only - -00:07:37.039 --> 00:07:39.759 -interested in the first one - -00:07:39.759 --> 00:07:42.000 -I'm making stuff up as I go here of - -00:07:42.000 --> 00:07:43.599 -course - -00:07:43.599 --> 00:07:46.000 -and whenever I hit enter I get a new - -00:07:46.000 --> 00:07:47.039 -buffer - -00:07:47.039 --> 00:07:50.160 -which just shows me this - -00:07:50.160 --> 00:07:53.520 -particular result for the particular - -00:07:53.520 --> 00:07:55.599 -query that I entered - -00:07:55.599 --> 00:07:59.199 -so let me do that again we are in here - -00:07:59.199 --> 00:08:03.199 -we are looking at a - -00:08:03.199 --> 00:08:05.840 -json file this can be very very big - -00:08:05.840 --> 00:08:07.520 -doesn't also need to be a file just - -00:08:07.520 --> 00:08:09.520 -needs to be a buffer - -00:08:09.520 --> 00:08:12.160 -you call console.jq on it and you can do - -00:08:12.160 --> 00:08:13.599 -any kind of - -00:08:13.599 --> 00:08:16.479 -query on it for example let's see if - -00:08:16.479 --> 00:08:18.080 -there is a url here - -00:08:18.080 --> 00:08:20.319 -yes there's a url let's see if there's a - -00:08:20.319 --> 00:08:23.759 -repository here repository - -00:08:23.759 --> 00:08:26.879 -no there isn't what was it called issue - -00:08:26.879 --> 00:08:33.440 -keys repository url it was called okay - -00:08:33.440 --> 00:08:36.640 -so let's see issue pause - -00:08:36.640 --> 00:08:40.240 -url and then we see so - -00:08:40.240 --> 00:08:42.959 -apparently this issue command is for a - -00:08:42.959 --> 00:08:44.159 -repository called - -00:08:44.159 --> 00:08:47.839 -organize I wonder what that might be - -00:08:47.839 --> 00:08:50.320 -okay so that was a very short - -00:08:50.320 --> 00:08:52.640 -introduction to console jq - -00:08:52.640 --> 00:08:54.800 -you can see the timer here I only have - -00:08:54.800 --> 00:08:56.800 -one minute left to go so I'm going to - -00:08:56.800 --> 00:08:57.440 -leave - -00:08:57.440 --> 00:08:59.760 -with a very very short introduction to - -00:08:59.760 --> 00:09:01.519 -the console gq - -00:09:01.519 --> 00:09:05.040 -code it's not even 60 lines - -00:09:05.040 --> 00:09:07.519 -of e-lisp so building something like - -00:09:07.519 --> 00:09:09.600 -this is very very easy - -00:09:09.600 --> 00:09:12.800 -I would encourage you to go and read - -00:09:12.800 --> 00:09:14.560 -through the code in your own time - -00:09:14.560 --> 00:09:16.160 -if you're interested in building - -00:09:16.160 --> 00:09:18.320 -something like this if you're interested - -00:09:18.320 --> 00:09:19.600 -in just using - -00:09:19.600 --> 00:09:22.720 -jq or you're done - -00:09:22.720 --> 00:09:24.320 -these are the links to all the tools - -00:09:24.320 --> 00:09:25.839 -console.jq of course - -00:09:25.839 --> 00:09:28.800 -is readily available on melpah also - -00:09:28.800 --> 00:09:29.519 -developed - -00:09:29.519

talk and part of +the EmacsConf 2020 schedule. + +00:00:18.000 --> 00:00:19.439 +This is what we're going to do. + +00:00:19.439 --> 00:00:22.320 +I'll make a quick introduction to the +topic at hand. + +00:00:22.320 --> 00:00:24.400 +I'll give you a demonstration of some +tools, + +00:00:24.400 --> 00:00:29.199 +and then we'll leave you +with the links to said tools. + +00:00:29.199 --> 00:00:31.679 +Before that, just a little bit about me. + +00:00:31.679 --> 00:00:40.399 +I am the CEO and co-founder of a company +based in the Swiss mountains called 200ok.ch. + +00:00:40.399 --> 00:00:44.879 +We are a product incubator and +service consultancy, + +00:00:44.879 --> 00:00:50.000 +but we like to spend most or at least as +much time as we can + +00:00:50.000 --> 00:00:52.719 +building free software. + +00:00:52.719 --> 00:00:56.879 +I'm also an ordained Zen monk and abbot +of the Lambda Zen temple. + +00:00:56.879 --> 00:01:04.159 +You can reach me anytime on questions +regarding Emacs, for example, + +00:01:04.159 --> 00:01:07.200 +at alain@200ok.ch. + +00:01:07.200 --> 00:01:09.439 +But back to the topic at hand. + +00:01:09.439 --> 00:01:11.760 +The proposition is as following: + +00:01:11.760 --> 00:01:14.000 +most work on the computer is based on +either + +00:01:14.000 --> 00:01:16.479 +text processing or text consumption. + +00:01:16.479 --> 00:01:22.799 +And very often, the text which you need +to process is in a structured format, + +00:01:22.799 --> 00:01:24.560 +for example, in JSON. + +00:01:24.560 --> 00:01:28.560 +That might even be if your job is not +programming per se. + +00:01:28.560 --> 00:01:33.119 +Reading through such a bigger chunk of +JSON can be non-trivial, however, + +00:01:33.119 --> 00:01:36.479 +while just reading and understanding it + +00:01:36.479 --> 00:01:40.320 +will be essential to getting your job +done. + +00:01:40.320 --> 00:01:44.479 +So let's quickly check out an example +JSON file. + +00:01:44.479 --> 00:01:47.200 +This is from the Github API, + +00:01:47.200 --> 00:01:52.079 +which is a request--sorry, the +response to a request + +00:01:52.079 --> 00:01:54.640 +for a specific issue on the github API. + +00:01:54.640 --> 00:01:58.799 +So let's quickly check that one out. + +00:01:58.799 --> 00:02:01.920 +Okay. So here it is open, and we can +already see + +00:02:01.920 --> 00:02:05.439 +that there is lots of stuff +going on here. + +00:02:05.439 --> 00:02:07.360 +It's 200 lines. + +00:02:07.360 --> 00:02:09.200 +It's not going to be very easy + +00:02:09.200 --> 00:02:11.840 +just to find out what are the top level +things in here, + +00:02:11.840 --> 00:02:13.360 +what are the top level attributes. + +00:02:13.360 --> 00:02:17.840 +Of course I can do this, and maybe do it +by hand, but that doesn't scale. + +00:02:17.840 --> 00:02:21.599 +I can use cool Emacs facilities like the +hideshow-mode + +00:02:21.599 --> 00:02:24.720 +and try to fold all the things that are +top level, + +00:02:24.720 --> 00:02:27.200 +but that also doesn't really scale. + +00:02:27.200 --> 00:02:29.360 +There must be a better way. + +00:02:29.360 --> 00:02:32.000 +Of course there is. There is prior art. + +00:02:32.000 --> 00:02:34.080 +There is a tool called jq. + +00:02:34.080 --> 00:02:37.760 +I'm going to quote the USP (unique selling proposition) from their website: + +00:02:37.760 --> 00:02:42.000 +jq is like sed for JSON data. + +00:02:42.000 --> 00:02:46.319 +you can use it to slice and filter and +map and transform structured data + +00:02:46.319 --> 00:02:47.840 +with the same ease that + +00:02:47.840 --> 00:02:54.000 +sed, awk, grep, and friends let you +play with text. + +00:02:54.000 --> 00:02:56.879 +Let me give you a quick demonstration of +it. + +00:02:56.879 --> 00:02:59.040 +By the way, it's written in portable C. + +00:02:59.040 --> 00:03:03.519 +It has zero runtime dependency, so it's +very easy to get started with it + +00:03:03.519 --> 00:03:09.840 +and use it on pretty much any UNIX-based +computer. + +00:03:09.840 --> 00:03:14.000 +Sorry, no, Linux-based computer, +apologies. + +00:03:14.000 --> 00:03:18.720 +Okay, so let's explore a +JSON file with it. + +00:03:18.720 --> 00:03:20.000 +It's a command line tool, + +00:03:20.000 --> 00:03:24.000 +and it has a very simple command +line syntax. + +00:03:24.000 --> 00:03:29.840 +So you call the binary and then you give +it a query and a file, + +00:03:29.840 --> 00:03:32.560 +and then it will return its answer. + +00:03:32.560 --> 00:03:35.440 +So, for example, if I want the top +level keys, + +00:03:35.440 --> 00:03:38.000 +I will just say jq keys the file + +00:03:38.000 --> 00:03:39.840 +and it will return the keys. + +00:03:39.840 --> 00:03:44.400 +Simple as that. So let's check this out +in a real shell. + +00:03:44.400 --> 00:03:46.879 +Here I am in eshell. + +00:03:46.879 --> 00:03:51.440 +Let's run jq keys on the Github issue comment. + +00:03:51.440 --> 00:03:58.799 +We can see that we have actually +received a list back here + +00:03:58.799 --> 00:04:00.319 +with the top-level things. + +00:04:00.319 --> 00:04:02.879 +So this issue... It looks very interesting. + +00:04:02.879 --> 00:04:07.360 +Let's ask it to give me more information on this issue. + +00:04:07.360 --> 00:04:11.360 +Then it's hairy again. That's a lot of stuff. + +00:04:11.360 --> 00:04:14.560 +I mean, lucky for us, we are in Emacs here, + +00:04:14.560 --> 00:04:16.720 +so we can use nice shortcuts. + +00:04:16.720 --> 00:04:22.000 +We can copy this. We can go in here, just select that, + +00:04:22.000 --> 00:04:24.160 +get that out or something like this. + +00:04:24.160 --> 00:04:32.320 +But still, this is not really the best way to do that, right? + +00:04:32.320 --> 00:04:34.080 +it gets kind of tedious. + +00:04:34.080 --> 00:04:37.680 +At this point the output can be humongous. + +00:04:37.680 --> 00:04:41.919 +The shell is not really the best place to read through such big output. + +00:04:41.919 --> 00:04:45.759 +I mean, eshell is probably one of the better shells for this, + +00:04:45.759 --> 00:04:47.919 +because it's just a regular Emacs buffer, + +00:04:47.919 --> 00:04:50.720 +but still, it's not really the best tool. + +00:04:50.720 --> 00:04:53.680 +I need to repeat the command all the time + +00:04:53.680 --> 00:04:56.000 +until I finally build the right query. + +00:04:56.000 --> 00:04:59.840 +And all the time, I lose my focus, + +00:04:59.840 --> 00:05:02.800 +I lose what I'm currently looking at. + +00:05:02.800 --> 00:05:05.520 +I'm seeing the new result. + +00:05:05.520 --> 00:05:08.160 +It would be so much nicer to have live feedback. + +00:05:08.160 --> 00:05:10.720 +When working with Emacs, we're quite used to that. + +00:05:10.720 --> 00:05:12.320 +So there should be an option. + +00:05:12.320 --> 00:05:15.120 +And of course there is. It's Emacs, right, + +00:05:15.120 --> 00:05:17.759 +so you can do anything. + +00:05:17.759 --> 00:05:22.960 +There is various good tools for completion in Emacs. + +00:05:22.960 --> 00:05:26.000 +I used ivy for this. + +00:05:26.000 --> 00:05:29.039 +I'm going to quote the USP for ivy. + +00:05:29.039 --> 00:05:32.639 +ivy is a generic completion mechanism for Emacs. + +00:05:32.639 --> 00:05:37.919 +While it operates similarly to other completion schemes such as icomplete mode, + +00:05:37.919 --> 00:05:42.160 +ivy aims to be more efficient, smaller, simpler, and smoother to use, + +00:05:42.160 --> 00:05:45.199 +yet highly customizable. + +00:05:45.199 --> 00:05:46.479 +And that's true. + +00:05:46.479 --> 00:05:49.440 +One of the cool things of ivy + +00:05:49.440 --> 00:05:54.320 +compared to other completion mechanisms in Emacs + +00:05:54.320 --> 00:05:59.120 +is that it can be used on dynamic data. + +00:05:59.120 --> 00:06:02.400 +So usually completion works on a static input. + +00:06:02.400 --> 00:06:05.360 +For example, you're in a buffer, a text buffer, + +00:06:05.360 --> 00:06:09.600 +and you use isearch maybe with ido-mode, + +00:06:09.600 --> 00:06:13.360 +and you find your results. That's all nice. + +00:06:13.360 --> 00:06:19.600 +However, if I want to search on dynamic data, + +00:06:19.600 --> 00:06:20.720 +that doesn't work. + +00:06:20.720 --> 00:06:24.880 +So whenever I type in my query for jq, + +00:06:24.880 --> 00:06:28.000 +I actually need to call the jq binary, + +00:06:28.000 --> 00:06:30.720 +and it will give a different result set back. + +00:06:30.720 --> 00:06:36.160 +So it's a really dynamic mechanism that we need here. + +00:06:36.160 --> 00:06:38.240 +It's much more like a search engine. + +00:06:38.240 --> 00:06:41.440 +ivy luckily has something built in, + +00:06:41.440 --> 00:06:43.520 +and it's called counsel. + +00:06:43.520 --> 00:06:47.360 +So I used counsel and jq and combined them, + +00:06:47.360 --> 00:06:49.199 +and built a new package + +00:06:49.199 --> 00:06:52.960 +with which we can use Emacs and jq + +00:06:52.960 --> 00:06:56.000 +to have live feedback. + +00:06:56.000 --> 00:06:57.759 +It's very easy to use. + +00:06:57.759 --> 00:06:59.840 +So you just call counsel-jq + +00:06:59.840 --> 00:07:02.160 +on a buffer containing JSON. + +00:07:02.160 --> 00:07:04.319 +For example, the one we have here. + +00:07:04.319 --> 00:07:06.800 +Let's call counsel-jq on it, + +00:07:06.800 --> 00:07:10.080 +and we already get a default query, + +00:07:10.080 --> 00:07:14.639 +the dot query, which just gives us the same file. + +00:07:14.639 --> 00:07:16.240 +But now we can change it. + +00:07:16.240 --> 00:07:18.639 +For example, find all the keys in here. + +00:07:18.639 --> 00:07:20.319 +And then we see I had this issue. + +00:07:20.319 --> 00:07:22.800 +This was the one that we were interested in. + +00:07:22.800 --> 00:07:25.599 +So let's find more information on the issue. + +00:07:25.599 --> 00:07:28.720 +What keys does it have actually have? + +00:07:28.720 --> 00:07:31.680 +It has assignees. That interests me. + +00:07:31.680 --> 00:07:34.800 +So let's check out the assignees in here. + +00:07:34.800 --> 00:07:39.759 +There's two of them, but I'm only interested in the first one. + +00:07:39.759 --> 00:07:43.599 +I'm making stuff up as I go here, of course. + +00:07:43.599 --> 00:07:47.039 +Whenever I hit enter, I get a new buffer + +00:07:47.039 --> 00:07:52.639 +which just shows me this particular result + +00:07:52.639 --> 00:07:55.599 +for the particular query that I entered. + +00:07:55.599 --> 00:07:57.680 +So let me do that again. + +00:07:57.680 --> 00:08:04.000 +We are in here. We are looking at a JSON file. + +00:08:04.000 --> 00:08:05.840 +This can be very, very big. + +00:08:05.840 --> 00:08:07.280 +Doesn't also need to be a file. + +00:08:07.280 --> 00:08:09.520 +Just needs to be a buffer. + +00:08:09.520 --> 00:08:11.360 +You call counsel-jq on it, + +00:08:11.360 --> 00:08:14.319 +and you can do any kind of query on it. + +00:08:14.319 --> 00:08:18.080 +For example, let's see if there is a URL here. + +00:08:18.080 --> 00:08:19.440 +Yes, there's a URL. + +00:08:19.440 --> 00:08:22.827 +Let's see if there's a repository here. + +00:08:22.827 --> 00:08:24.639 +Repository. No, there isn't. + +00:08:24.639 --> 00:08:33.440 +What was it called? Issue. Keys. Repository URL, it was called. + +00:08:33.440 --> 00:08:38.240 +So let's see issue repository URL, + +00:08:38.240 --> 00:08:39.519 +and then we see. + +00:08:39.519 --> 00:08:44.800 +So apparently this issue comment is for a repository called organice. + +00:08:44.800 --> 00:08:47.839 +I wonder what that might be. + +00:08:47.839 --> 00:08:52.640 +Okay. So that was a very short introduction to counsel-jq. + +00:08:52.640 --> 00:08:54.240 +You can see the timer here. + +00:08:54.240 --> 00:08:57.440 +I only have one minute left to go, so I'm going to leave + +00:08:57.440 --> 00:09:02.880 +with a very, very short introduction to the counsel-jq code. + +00:09:02.880 --> 00:09:06.000 +It's not even 60 lines of elisp, + +00:09:06.000 --> 00:09:09.600 +so building something like this is very, very easy. + +00:09:09.600 --> 00:09:14.560 +I would encourage you to go and read through the code in your own time, + +00:09:14.560 --> 00:09:17.519 +if you're interested in building something like this. + +00:09:17.519 --> 00:09:22.720 +If you're interested in just using jq or you're done, + +00:09:22.720 --> 00:09:24.320 +these are the links to all the tools. + +00:09:24.320 --> 00:09:28.240 +counsel-jq, of course, is readily available on MELPA. + +00:09:28.240 --> 00:09:32.959 +Also developed under the AGPL license on Github. + +00:09:32.959 --> 00:09:36.080 +And this organice thing, by the way, it's + +00:09:36.080 --> 00:09:38.560 +Org Mode for mobile and desktop browsers. + +00:09:38.560 --> 00:09:43.120 +Also a great free software tool maybe that interests you. + +00:09:43.120 --> 00:09:46.240 +Thank you for listening. Have a great time. + +00:09:46.240 --> 00:09:49.360 +10 seconds left. I am going to stop this now. + +00:09:49.360 --> 00:09:53.920 +Enjoy EmacsConf.

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

So who am I? I am a senior at +Stanford Online High School, + +00:00:19.520 --> 00:00:22.800 +and I am also a violinist. + +00:00:22.800 --> 00:00:25.199 +I started violin when I was two and a half, + +00:00:25.199 --> 00:00:28.560 +and I have been keeping it up ever since. + +00:00:28.560 --> 00:00:30.240 +Violin is a huge part of my life, + +00:00:30.240 --> 00:00:33.360 +and I am very much a musician at heart. + +00:00:33.360 --> 00:00:36.239 +I am also a somewhat capable programmer. + +00:00:36.239 --> 00:00:39.280 +I've done a lot of informal programming in the past, + +00:00:39.280 --> 00:00:45.840 +and this year I'm taking my first AP Comp. Sci. course in my high school. + +00:00:45.840 --> 00:00:51.039 +And so I've done a lot of side projects, + +00:00:51.039 --> 00:00:56.800 +mainly in Python, and some very short scripts in Elisp. + +00:00:56.800 --> 00:00:59.840 +And last but not least, I am a tinker. + +00:00:59.840 --> 00:01:05.280 +I love to play around with things and see what I can do better, + +00:01:05.280 --> 00:01:10.880 +and just have as much fun as possible. + +00:01:10.880 --> 00:01:15.040 +So how did I find Emacs? + +00:01:15.040 --> 00:01:18.880 +I discovered it actually through a talk, funnily enough, + +00:01:18.880 --> 00:01:23.947 +at a Vim conference given by Aaron Bieber, titled: + +00:01:23.947 --> 00:01:28.320 +"Evil Mode or How I Learned to Stop Worrying and Love Emacs." + +00:01:28.320 --> 00:01:31.439 +I watched that talk a couple times over, + +00:01:31.439 --> 00:01:35.759 +just marveling at all the wonderful things that he could do in Emacs. + +00:01:35.759 --> 00:01:38.799 +And being a previous Vim user myself, + +00:01:38.799 --> 00:01:42.399 +I found it very enticing to be able to have + +00:01:42.399 --> 00:01:47.040 +the evil-mode package and very quickly switch to Emacs. + +00:01:47.040 --> 00:01:49.680 +At the time, I was also in my sophomore year, + +00:01:49.680 --> 00:01:56.320 +and so I had had a sort of a note-taking system +in the past. + +00:01:56.320 --> 00:02:01.680 +But it was not good, and I needed a more organized note-taking system. + +00:02:01.680 --> 00:02:04.240 +My parents had suggested paper for a while, + +00:02:04.240 --> 00:02:09.759 +and there was the whole organization part of that, + +00:02:09.759 --> 00:02:12.080 +but that did not really work out for me. + +00:02:12.080 --> 00:02:16.239 +And so I was trying to find this better note-taking system, + +00:02:16.239 --> 00:02:19.440 +and it was very hard. + +00:02:19.440 --> 00:02:23.520 +I had two main criteria which I did not define at the time, + +00:02:23.520 --> 00:02:26.640 +but I realized was really what I was looking for. + +00:02:26.640 --> 00:02:29.599 +First of all, it had to be flexible enough, + +00:02:29.599 --> 00:02:33.680 +and second of all, I had to have control over the data. + +00:02:33.680 --> 00:02:36.239 +And so through this process, + +00:02:36.239 --> 00:02:41.920 +I actually went through a bunch of note-taking softwares rather systematically. + +00:02:41.920 --> 00:02:47.519 +I went through Google Docs, which very much did not work out. + +00:02:47.519 --> 00:02:52.080 +I also went through Evernote which also was not great for me, + +00:02:52.080 --> 00:02:55.200 +and OneNote, which I settled on for a little while, + +00:02:55.200 --> 00:02:58.800 +but it did not meet these criteria, + +00:02:58.800 --> 00:03:00.879 +particularly the second one. + +00:03:00.879 --> 00:03:03.840 +I had taken some notes and I wanted to export it, + +00:03:03.840 --> 00:03:07.519 +and OneNote did not let me do that. + +00:03:07.519 --> 00:03:12.000 +It was PDF. Horribly-organized PDF. + +00:03:12.000 --> 00:03:17.440 +And that's when I knew I needed some change. + +00:03:17.440 --> 00:03:21.519 +So I discovered Emacs through this talk, + +00:03:21.519 --> 00:03:27.040 +and through the wonderful features of Org Mode. + +00:03:27.040 --> 00:03:30.080 +This is my first journal entry in Emacs. + +00:03:30.080 --> 00:03:34.000 +I had been playing with it for one day, + +00:03:34.000 --> 00:03:35.760 +and I was on the Org Agenda, + +00:03:35.760 --> 00:03:38.159 +and I happened to press I, + +00:03:38.159 --> 00:03:43.040 +which for the Emacs keybinding is the default for diary entry. + +00:03:43.040 --> 00:03:45.440 +I was very excited. + +00:03:45.440 --> 00:03:50.239 +I shouldn't stay on the slide too long lest you read it. + +00:03:50.239 --> 00:03:53.760 +So let's move on to the next one. + +00:03:53.760 --> 00:03:57.200 +So the learning curve for me, I think, + +00:03:57.200 --> 00:04:00.480 +particularly being an ex-Vim user, + +00:04:00.480 --> 00:04:03.760 +evil-mode made it very easy to switch. + +00:04:03.760 --> 00:04:07.439 +Thankfully, there was the Emacs reference sheet, + +00:04:07.439 --> 00:04:16.160 +and having evil-mode to switch between texts... + +00:04:16.160 --> 00:04:17.919 +Whether it be editing a text file, + +00:04:17.919 --> 00:04:21.600 +or going to other parts of just Emacs in general, + +00:04:21.600 --> 00:04:25.520 +I think Vim really helped with making me feel comfortable + +00:04:25.520 --> 00:04:28.000 +within this new environment. + +00:04:28.000 --> 00:04:32.160 +So, having that experience, I also wasn't new + +00:04:32.160 --> 00:04:33.759 +to the keybind-based world. + +00:04:33.759 --> 00:04:36.320 +I have been very comfortable with the computer + +00:04:36.320 --> 00:04:40.160 +and the keyboard for most of my life, + +00:04:40.160 --> 00:04:45.520 +and so it was not a totally new environment for me. + +00:04:45.520 --> 00:04:49.360 +I also spent a lot of time looking at the Emacs reference sheet, + +00:04:49.360 --> 00:04:54.720 +Just thinking about trying to find all of the different functions. + +00:04:54.720 --> 00:04:58.720 +If I didn't know what something was, then I queried it in Emacs, + +00:04:58.720 --> 00:05:01.199 +and then I figured out what it was. + +00:05:01.199 --> 00:05:05.600 +And that was one of the best ways for me to discover + +00:05:05.600 --> 00:05:09.360 +all of the capabilities of Emacs. + +00:05:09.360 --> 00:05:12.800 +Thirdly, of course, the self-documenting feature + +00:05:12.800 --> 00:05:17.120 +or nature of Emacs and narrowing frameworks such as helm + +00:05:17.120 --> 00:05:21.360 +really helped find things, especially for M-x. + +00:05:21.360 --> 00:05:25.919 +For a while, I was just... + +00:05:25.919 --> 00:05:30.720 +I would go about my day, and if I pressed a keybind that I didn't know what it did, + +00:05:30.720 --> 00:05:37.039 +I would do the lossage and see the list of keybinds that I had pressed + +00:05:37.039 --> 00:05:43.039 +and tried to find that one, and query the function and what not. + +00:05:43.039 --> 00:05:48.160 +So yeah. And now we jump to now. + +00:05:48.160 --> 00:05:53.280 +So there is at least one moment in each day when I think + +00:05:53.280 --> 00:05:55.600 +how would I live without Emacs, + +00:05:55.600 --> 00:05:59.120 +particularly now during my senior year in high school. + +00:05:59.120 --> 00:06:04.880 +Things are very busy with school, violin, and other side projects. + +00:06:04.880 --> 00:06:12.720 +It's pretty crazy, and so Emacs and Org Mode has really helped me stay + +00:06:12.720 --> 00:06:14.479 +on track with everything. + +00:06:14.479 --> 00:06:16.319 +And the flexibility of these software + +00:06:16.319 --> 00:06:19.919 +is being able to have things in different files, + +00:06:19.919 --> 00:06:21.600 +notes within the tasks, + +00:06:21.600 --> 00:06:25.840 +all of that stuff has been truly a lifesaver. + +00:06:25.840 --> 00:06:28.400 +And so I think I can confidently say + +00:06:28.400 --> 00:06:35.280 +that I have found Emacs to be the perfect software for me + +00:06:35.280 --> 00:06:38.639 +over the past two years of using Emacs. + +00:06:38.639 --> 00:06:42.240 +Now it is about two years and two months. + +00:06:42.240 --> 00:06:45.039 +I have built a fairly well organized + +00:06:45.039 --> 00:06:49.520 +2000+ line Org literate config. + +00:06:49.520 --> 00:06:53.840 +I actually started with an Elisp config, + +00:06:53.840 --> 00:06:56.800 +just the vanilla Emacs with evil-mode, + +00:06:56.800 --> 00:06:59.039 +and I built it up from there. + +00:06:59.039 --> 00:07:02.400 +Eventually I switched to Org literate configs, + +00:07:02.400 --> 00:07:05.840 +and used that to organize the snippets + +00:07:05.840 --> 00:07:08.639 +that I was putting in there. + +00:07:08.639 --> 00:07:14.000 +So yeah, this is really my workflow now. + +00:07:14.000 --> 00:07:18.960 +Currently about 90% of everything I do on my computer is in Emacs. + +00:07:18.960 --> 00:07:21.360 +The most notable things, of course-- + +00:07:21.360 --> 00:07:25.280 +the list is far too long to put on one slide-- + +00:07:25.280 --> 00:07:28.160 +but I do a lot of my programming in Emacs, + +00:07:28.160 --> 00:07:31.280 +mainly Python and Elisp. + +00:07:31.280 --> 00:07:33.199 +Because of my AP Comp. Sci. class, + +00:07:33.199 --> 00:07:35.199 +I have to do Java as well, + +00:07:35.199 --> 00:07:41.840 +and thank goodness Emacs has wonderful support for that as well. + +00:07:41.840 --> 00:07:45.840 +Also, I do all of my school assignments, + +00:07:45.840 --> 00:07:47.840 +more or less, in Emacs. + +00:07:47.840 --> 00:07:51.919 +Essay writing I do in Org Mode, and I have some template files, + +00:07:51.919 --> 00:07:55.039 +template Org files which I just include at the top, + +00:07:55.039 --> 00:08:01.440 +and then I can export easily to LaTeX and a beautiful PDF. + +00:08:01.440 --> 00:08:03.440 +Math, physics, same thing. + +00:08:03.440 --> 00:08:09.599 +LaTeX fragments are a lifesaver, and also really pretty. + +00:08:09.599 --> 00:08:13.199 +I take notes on basically everything. + +00:08:13.199 --> 00:08:15.120 +At first, I had things separate, + +00:08:15.120 --> 00:08:19.680 +and then I started sort of putting it all into one notes.org file, + +00:08:19.680 --> 00:08:22.479 +or most of it into one file, + +00:08:22.479 --> 00:08:24.960 +and that has actually worked out surprisingly well, + +00:08:24.960 --> 00:08:30.442 +especially with all the searching +features of agenda and what not. + +00:08:30.442 --> 00:08:33.440 +And I also use mail. + +00:08:33.440 --> 00:08:37.680 +I recently made the switch, probably about one or two months ago, + +00:08:37.680 --> 00:08:42.399 +and it has been one of the best switches I've ever had, + +00:08:42.399 --> 00:08:47.839 +especially given connecting to tasks all of this wonderful stuff. + +00:08:47.839 --> 00:08:54.160 +Just putting even more in Emacs is always a good thing, I found. + +00:08:54.160 --> 00:08:56.959 +So reflecting back on my journey, + +00:08:56.959 --> 00:08:59.600 +I think one of the most important things + +00:08:59.600 --> 00:09:01.440 +was just having a reason to use it. + +00:09:01.440 --> 00:09:06.080 +When I came to Emacs I had something that I was looking for, + +00:09:06.080 --> 00:09:09.839 +and as soon as I found it, I delved right in, + +00:09:09.839 --> 00:09:12.720 +and I started using it for that thing. + +00:09:12.720 --> 00:09:16.240 +So I was sort of forced to take the time to read the docs + +00:09:16.240 --> 00:09:20.880 +and figure out what functions I needed to function + +00:09:20.880 --> 00:09:25.839 +and how I was going to put my workflow, + +00:09:25.839 --> 00:09:30.399 +and also, of course, the desire to tinker. + +00:09:30.399 --> 00:09:35.839 +So, really, what's next for me is just wanting to become + +00:09:35.839 --> 00:09:38.640 +a more active member of the Emacs community. + +00:09:38.640 --> 00:09:40.959 +I want to give back, and I think this talk + +00:09:40.959 --> 00:09:43.760 +is sort of the first step to that + +00:09:43.760 --> 00:09:46.399 +being a more active part of this community + +00:09:46.399 --> 00:09:52.720 +that has, indirectly, perhaps, but just really helped me + +00:09:52.720 --> 00:09:55.839 +become a better and more organized human being. + +00:09:55.839 --> 00:10:00.240 +I have some package ideas that I'm slowly working on, + +00:10:00.240 --> 00:10:05.920 +and yeah, I just hope to spread the word. + +00:10:05.920 --> 00:10:09.360 +So thank you very much for listening to my lightning talk. + +00:10:09.360 --> 00:10:11.360 +If you'd like to contact me here are + +00:10:11.360 --> 00:10:14.800 +three modes of or two modes of communication. + +00:10:14.800 --> 00:10:17.600 +I will be on IRC more soon, + +00:10:17.600 --> 00:10:22.079 +and you can always email me if you have any questions. + +00:10:22.079 --> 00:10:25.519 +You can also search me on Youtube: Pierce Wang violin. + +00:10:25.519 --> 00:10:33.040 +Thank you very much and I hope you enjoy the rest of the conference. diff --git a/2020/subtitles/emacsconf-2020--27-state-of-retro-gaming-in-emacs-chip8--vasilij-wasamasa-schneidermann-autogen.vtt b/2020/subtitles/emacsconf-2020--27-state-of-retro-gaming-in-emacs-chip8--vasilij-wasamasa-schneidermann-autogen.vtt deleted file mode 100644 index 1d41f1e5..00000000 --- a/2020/subtitles/emacsconf-2020--27-state-of-retro-gaming-in-emacs-chip8--vasilij-wasamasa-schneidermann-autogen.vtt +++ /dev/null @@ -1,913 +0,0 @@ -WEBVTT -

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

I'm 28 years old. + +00:00:12.000 --> 00:00:14.719 +I work as a cyber security consultant at msg systems, + +00:00:14.719 --> 00:00:17.359 +and test other people's web applications + +00:00:17.359 --> 00:00:20.160 +and review the source code for security problems. + +00:00:20.160 --> 00:00:22.080 +You can reach me by email. + +00:00:22.080 --> 00:00:25.039 +I have my own self-hosted git repositories, + +00:00:25.039 --> 00:00:28.160 +and I have a blog where you can occasionally find new posts by me + +00:00:28.160 --> 00:00:32.160 +on all kinds of things, not just Emacs things. + +00:00:32.160 --> 00:00:34.559 +The motivation about this one... + +00:00:34.559 --> 00:00:37.600 +I found that Emacs is the ultimate procrastination machine, + +00:00:37.600 --> 00:00:39.600 +and there are lots of fun demonstrations. + +00:00:39.600 --> 00:00:41.200 +I'll go over a few of them. + +00:00:41.200 --> 00:00:45.840 +For example, someone made a thing to order salad for himself online, + +00:00:45.840 --> 00:00:48.239 +so he doesn't have to walk over to the shop. + +00:00:48.239 --> 00:00:51.760 +There's plenty of IRC bots. There's some game things. + +00:00:51.760 --> 00:00:55.600 +There's an emulator for the Z-machine +which you can use to play zork. + +00:00:55.600 --> 00:00:57.440 +And so I asked myself, at this point, + +00:00:57.440 --> 00:00:59.920 +can you actually emulate retro games at 60fps? + +00:00:59.920 --> 00:01:02.079 +I looked around a bit and found some projects, + +00:01:02.079 --> 00:01:06.159 +but none that were actually able to do it at 60fps. + +00:01:06.159 --> 00:01:08.000 +So I set out to do my own one, + +00:01:08.000 --> 00:01:09.200 +and looked out for a console + +00:01:09.200 --> 00:01:11.119 +that you can actually emulate at that speed, + +00:01:11.119 --> 00:01:14.690 +using Emacs with its very, very limited rendering. + +00:01:16.320 --> 00:01:19.200 +And here's the project, chip8.el. + +00:01:19.200 --> 00:01:20.560 +It's pretty much finished. + +00:01:20.560 --> 00:01:24.000 +It clocks into under 1000 source lines of code. + +00:01:24.000 --> 00:01:26.159 +It supports the superchip 8 extensions. + +00:01:26.159 --> 00:01:27.280 +It runs at full speed. + +00:01:27.280 --> 00:01:29.600 +All games behave okay, as far as I'm concerned, + +00:01:29.600 --> 00:01:31.680 +and yeah, I'm pretty happy with it. + +00:01:31.680 --> 00:01:34.479 +It's very much the hello world of emulation, + +00:01:34.479 --> 00:01:40.880 +and I might, maybe, do some other emulation projects in the future. + +00:01:40.880 --> 00:01:43.360 +Now, for the section which is the longest: + +00:01:43.360 --> 00:01:45.439 +bunch of fun facts about chip8.el + +00:01:45.439 --> 00:01:49.200 +which I've learned during this project. + +00:01:49.200 --> 00:01:51.759 +So what the hell is chip8 anyway? + +00:01:51.759 --> 00:01:54.960 +First of all, unlike many other emulation game things, + +00:01:54.960 --> 00:01:56.799 +it's not a console, but a VM. + +00:01:56.799 --> 00:02:00.000 +It was designed for easy porting of home +computer games. + +00:02:00.000 --> 00:02:02.320 +It wasn't terribly successful, + +00:02:02.320 --> 00:02:05.439 +but there's still a small community of enthusiasts writing games for it, + +00:02:05.439 --> 00:02:09.119 +and there are even a few demos. + +00:02:09.119 --> 00:02:11.039 +This VM has system specs. + +00:02:11.039 --> 00:02:14.720 +It has a very, very simple 8-bit cpu with 16 registers, + +00:02:14.720 --> 00:02:17.280 +and 36 fixed-size instructions. + +00:02:17.280 --> 00:02:19.680 +You have a whole 4 kilobyte of RAM. + +00:02:19.680 --> 00:02:22.080 +You have a stack with 16 return addresses. + +00:02:22.080 --> 00:02:25.760 +The resolution is 64 by 32 black/white pixels. + +00:02:25.760 --> 00:02:28.000 +Rendering is done by drawing sprites. + +00:02:28.000 --> 00:02:29.200 +These are drawn in XOR mode, + +00:02:29.200 --> 00:02:31.840 +meaning that if you draw a sprite and set a bit, + +00:02:31.840 --> 00:02:35.040 +it just flips over from black to white or white to black. + +00:02:35.040 --> 00:02:39.360 +For sound, you have a monotone buzzer that can just beep at one frequency. + +00:02:39.360 --> 00:02:43.120 +Most unusually, there's a hexadecimal keypad as input, + +00:02:43.120 --> 00:02:48.480 +so the keys are basically zero to nine and a to f. + +00:02:48.480 --> 00:02:50.720 +So how does this whole thing work? + +00:02:50.720 --> 00:02:52.400 +It runs at an unspecified speed. + +00:02:52.400 --> 00:02:53.040 +You'll probably have to do some fine-tuning + +00:02:53.040 --> 00:02:56.080 +to find the speed you're happy with. + +00:02:56.080 --> 00:02:58.080 +Sound and delay timers exist. + +00:02:58.080 --> 00:03:01.120 +They count down at 60fps down to 0. + +00:03:01.120 --> 00:03:05.120 +This is done so that you can play a sound at some specific time. + +00:03:05.120 --> 00:03:07.840 +The game itself is loaded with a fixed offset into RAM. + +00:03:07.840 --> 00:03:10.480 +The program counter is set to exactly that offset, + +00:03:10.480 --> 00:03:11.920 +and from there it enters the game loop + +00:03:11.920 --> 00:03:13.280 +where it decodes an instruction, + +00:03:13.280 --> 00:03:14.800 +executes it for the side effects, + +00:03:14.800 --> 00:03:18.130 +and just loops and does this ad infinitum. + +00:03:19.599 --> 00:03:22.720 +So the game loop was the first thing where we ran into problems. + +00:03:22.720 --> 00:03:25.120 +The usual game approach is to do stuff, + +00:03:25.120 --> 00:03:26.640 +figure out how long to wait, + +00:03:26.640 --> 00:03:29.280 +wait for exactly that much, and repeat. + +00:03:29.280 --> 00:03:31.680 +This doesn't work well in Emacs at all, because, well, + +00:03:31.680 --> 00:03:34.959 +user input, basically. + +00:03:34.959 --> 00:03:37.760 +Emacs is designed to just do whatever it needs to do + +00:03:37.760 --> 00:03:39.040 +whenever you enter user input + +00:03:39.040 --> 00:03:42.319 +instead of doing things at one specific time. + +00:03:42.319 --> 00:03:46.640 +If you try to do interruptable sleep, well, you get unpredictable behavior. + +00:03:46.640 --> 00:03:50.480 +For example, it can be the timer doesn't run at all at the next time + +00:03:50.480 --> 00:03:52.560 +because you've accidentally cancelled it. + +00:03:52.560 --> 00:03:55.120 +If you do uninterruptable sleep, it freezes instead , + +00:03:55.120 --> 00:03:56.720 +which isn't what we want either. + +00:03:56.720 --> 00:04:00.560 +So I went for timers, which forced me to do inversion of control, + +00:04:00.560 --> 00:04:02.560 +meaning that I have to write code in the style + +00:04:02.560 --> 00:04:04.879 +where it just calls timer, + +00:04:04.879 --> 00:04:06.560 +and this allows this input to happen + +00:04:06.560 --> 00:04:11.040 +and for things to progress at roughly the speed I want to. + +00:04:11.040 --> 00:04:14.159 +So there's the timer function which is called at 60fps + +00:04:14.159 --> 00:04:17.359 +and I have to be very careful to not do too much in it. + +00:04:17.359 --> 00:04:21.305 +And, say, this function executes CPU cycles, + +00:04:21.305 --> 00:04:26.479 +decrement the sound/delay registers, and redraw the screen. + +00:04:26.479 --> 00:04:28.800 +So to map this whole system to Emacs Lisp, + +00:04:28.800 --> 00:04:31.199 +I've used just integers and vectors + +00:04:31.199 --> 00:04:33.120 +which contain even more integers. + +00:04:33.120 --> 00:04:35.040 +This is used for the RAM, registers, + +00:04:35.040 --> 00:04:37.040 +return stack, key state, screen, + +00:04:37.040 --> 00:04:38.508 +and so on and so forth. + +00:04:38.508 --> 00:04:41.520 +Basically, what you would do if you were writing C. + +00:04:41.520 --> 00:04:43.360 +All of this is stored in global variables. + +00:04:43.360 --> 00:04:45.600 +I'm not using any lists at all. + +00:04:45.600 --> 00:04:48.400 +As a side effect, there's no consing going on at all. + +00:04:48.400 --> 00:04:50.080 +There are no extra objects created + +00:04:50.080 --> 00:04:53.199 +which would trigger garbage collection processes. + +00:04:53.199 --> 00:04:55.600 +Getting this right was rather tricky, actually, + +00:04:55.600 --> 00:04:58.240 +and there were some hidden garbage collection problems + +00:04:58.240 --> 00:05:01.759 +which I had to resolve over time. + +00:05:01.759 --> 00:05:03.759 +So, decoding instructions. + +00:05:03.759 --> 00:05:06.800 +For this, you have to know that all instructions are two bytes long, + +00:05:06.800 --> 00:05:08.880 +and the arguments are encoded inside them. + +00:05:08.880 --> 00:05:11.440 +For example, the jump to address instruction + +00:05:11.440 --> 00:05:15.120 +is encoded as one and three hex digits. + +00:05:15.120 --> 00:05:18.400 +The type is extracted masking with #xF000 + +00:05:18.400 --> 00:05:20.400 +and then shifting it by 12 bits. + +00:05:20.400 --> 00:05:23.520 +Mask means you perform the binary AND. + +00:05:23.520 --> 00:05:28.400 +You can do the same with the argument by masking with #0xFFF and no shift. + +00:05:28.400 --> 00:05:30.560 +If you do this long enough, you'll find common patterns. + +00:05:30.560 --> 00:05:32.639 +For example, addresses are always encoded like this + +00:05:32.639 --> 00:05:34.880 +using the last three nibbles. + +00:05:34.880 --> 00:05:36.160 +In the code, you'll find a big cond + +00:05:36.160 --> 00:05:40.070 +which dispatches on the type and executes it for the side effects. + +00:05:41.440 --> 00:05:45.919 +For testing, I've initially just executed the ROM until I've hit C-g, + +00:05:45.919 --> 00:05:49.039 +and then use the debug command to render the screen to a buffer. + +00:05:49.039 --> 00:05:53.199 +Later on, I found tiny ROMs that just display a static test screen, + +00:05:53.199 --> 00:05:57.280 +for example, logo, and looked whether it looked right. + +00:05:57.280 --> 00:05:58.800 +I added instructions as needed + +00:05:58.800 --> 00:06:00.720 +and went through more and more and more ROMs. + +00:06:00.720 --> 00:06:04.000 +And later I wrote a unit test suite as a safety net. + +00:06:04.000 --> 00:06:07.840 +This unit test suite, it just sets up an empty emulator state, + +00:06:07.840 --> 00:06:09.199 +executes some instructions, + +00:06:09.199 --> 00:06:14.880 +and then looks whether the expected side effects have happened. + +00:06:14.880 --> 00:06:18.319 +For debugging, I usually use edebug, but this was super ineffective, + +00:06:18.319 --> 00:06:21.600 +because, well, you don't really want to step through big cons + +00:06:21.600 --> 00:06:23.680 +doing side effects for every single cycle, + +00:06:23.680 --> 00:06:26.880 +when it can take like 100 cycles for things to happen. + +00:06:26.880 --> 00:06:29.680 +Therefore I've set up logging. + +00:06:29.680 --> 00:06:32.639 +Whenever I logged something and couldn't figure out the error, + +00:06:32.639 --> 00:06:37.039 +I compared my log output with the instrumented version of another emulator, + +00:06:37.039 --> 00:06:40.479 +and if the logs diverge, then I have figured out where the bug lies + +00:06:40.479 --> 00:06:42.720 +and could look deeper into it. + +00:06:42.720 --> 00:06:44.960 +Future project idea might be a chip 8 debugger, + +00:06:44.960 --> 00:06:49.440 +but I doubt I'll ever go into it. + +00:06:49.440 --> 00:06:51.759 +For analysis, I initially wrote a disassembler, + +00:06:51.759 --> 00:06:54.400 +which is a very simple thing but super tedious, + +00:06:54.400 --> 00:06:56.639 +especially if you wanted to add advanced functionality, + +00:06:56.639 --> 00:06:58.720 +for example, analysis or thinking of what part is data, + +00:06:58.720 --> 00:07:00.000 +what part is code. + +00:07:00.000 --> 00:07:03.360 +I had this great idea for using the radare 2 framework + +00:07:03.360 --> 00:07:06.479 +and adding analysis and disassembly plug-in for it. + +00:07:06.479 --> 00:07:08.400 +So I looked into this. Found, okay, + +00:07:08.400 --> 00:07:10.319 +you can write plugins in C + +00:07:10.319 --> 00:07:12.639 +but also in Python, so I wrote one in Python, + +00:07:12.639 --> 00:07:14.720 +and then discovered there's actually an existing one in core, + +00:07:14.720 --> 00:07:18.400 +which you have to enable explicitly by passing an extra argument. + +00:07:18.400 --> 00:07:21.680 +I've tried it and found it's not exactly as good as my own one, + +00:07:21.680 --> 00:07:24.160 +so I improved this one and submitted pull requests + +00:07:24.160 --> 00:07:26.610 +until it was at the same level. + +00:07:28.080 --> 00:07:30.720 +Rendering was the trickiest part of this whole thing, + +00:07:30.720 --> 00:07:34.319 +because, well, I decided against using a library. + +00:07:34.319 --> 00:07:37.120 +Not like there would have been any usable library for this. + +00:07:37.120 --> 00:07:40.880 +My usual approach of creating SVG files was too expensive. + +00:07:40.880 --> 00:07:45.120 +It just created too much garbage and took too long time. + +00:07:45.120 --> 00:07:47.360 +I then tried creating mutating strings. + +00:07:47.360 --> 00:07:52.479 +This was either too expensive, just like SVGs, or too complicated. + +00:07:52.479 --> 00:07:57.280 +I tried changing SVG tiles, which created gaps between the lines. + +00:07:57.280 --> 00:08:00.720 +Then I tried to create an xpm file which was backed by a bool vector + +00:08:00.720 --> 00:08:02.400 +and mutating this bool vector, + +00:08:02.400 --> 00:08:04.000 +but the image caching effect + +00:08:04.000 --> 00:08:06.479 +made it just every nth frame to appear, + +00:08:06.479 --> 00:08:08.879 +which wasn't good either. + +00:08:08.879 --> 00:08:11.440 +Then I had the idea to just use plain text + +00:08:11.440 --> 00:08:13.120 +and paint the individual characters + +00:08:13.120 --> 00:08:14.800 +with a different background color. + +00:08:14.800 --> 00:08:17.120 +This had perfect, perfect performance. + +00:08:17.120 --> 00:08:19.280 +There were many optimization attempts until I got there, + +00:08:19.280 --> 00:08:21.199 +and it was very, very stressful. + +00:08:21.199 --> 00:08:26.160 +I wasn't sure whether I would ever get to accept the performance at all. + +00:08:26.160 --> 00:08:28.560 +For sound you only need to do a single beep, + +00:08:28.560 --> 00:08:31.280 +so technically, it shouldn't be difficult to emulate it. + +00:08:31.280 --> 00:08:33.039 +However, doing this is hard because + +00:08:33.039 --> 00:08:37.200 +Emacs officially only supports synchronous playback of sounds. + +00:08:37.200 --> 00:08:41.360 +But there's also Emacs process, which you can launch in asynchronous way. + +00:08:41.360 --> 00:08:44.720 +So I looked into it and found that mplayer has a slave mode + +00:08:44.720 --> 00:08:48.640 +and mpv supports listing on the fifo for commands. + +00:08:48.640 --> 00:08:53.760 +So I've created a pipe, started a paused MPV in loop mode, + +00:08:53.760 --> 00:08:56.560 +and always send in pause and unpause command to the FIFO, + +00:08:56.560 --> 00:08:58.000 +and that way I could control + +00:08:58.000 --> 00:09:02.640 +when to start beeping and stop beeping. + +00:09:02.640 --> 00:09:04.160 +So yeah, that's it so far. + +00:09:04.160 --> 00:09:07.200 +It was a very educational experience. + +00:09:07.200 --> 00:09:10.320 +I have tried out a bunch of games which were, + +00:09:10.320 --> 00:09:14.320 +well, I almost say the worst ports of classic games I've ever tried. + +00:09:14.320 --> 00:09:15.680 +It wasn't terribly fun to play them, + +00:09:15.680 --> 00:09:18.555 +but was fun to improve the emulator + +00:09:18.555 --> 00:09:21.760 +until, well, things worked good enough. + +00:09:21.760 --> 00:09:25.120 +I've learned a lot about how computers work at this level, + +00:09:25.120 --> 00:09:28.880 +so, maybe, maybe I'll in the future make another emulator, + +00:09:28.880 --> 00:09:34.000 +but I'm not sure whether anything more advanced, like an Intel 8080 emulator, + +00:09:34.000 --> 00:09:36.560 +will actually run in Emacs fast enough, + +00:09:36.560 --> 00:09:37.839 +but it's still an interesting idea, + +00:09:37.839 --> 00:09:40.800 +because then you could actually have an OS inside Emacs + +00:09:40.800 --> 00:09:43.120 +and fulfill that one specific meme. + +00:09:43.120 --> 00:09:45.440 +But if I try to do most serious stuff, + +00:09:45.440 --> 00:09:47.040 +I'll probably use Chicken Scheme, + +00:09:47.040 --> 00:09:49.920 +which is my preferred language for serious projects, + +00:09:49.920 --> 00:09:53.279 +and write a NES game emulator. + +00:09:53.279 --> 00:09:57.839 +And that's it.

-00:13:27.760 --> 00:13:30.959 -so creating any free software any - -00:13:30.959 --> 00:13:33.040 -self-organizing free software project - -00:13:33.040 --> 00:13:36.000 -is is challenging to start with and - -00:13:36.000 --> 00:13:37.200 -we're generally - -00:13:37.200 --> 00:13:38.480 -people with a bunch of other - -00:13:38.480 --> 00:13:40.320 -responsibilities by the time we get to - -00:13:40.320 --> 00:13:40.560 -it - -00:13:40.560 --> 00:13:44.000 -so it's it's not just hey - -00:13:44.000 --> 00:13:47.040 -you know the general herding cats it's - -00:13:47.040 --> 00:13:47.680 -it's - -00:13:47.680 --> 00:13:49.120 -you know trying to make it a part of - -00:13:49.120 --> 00:13:51.040 -your life to - -00:13:51.040 --> 00:13:54.399 -uh that being kind of a - -00:13:54.399 --> 00:13:57.680 -you know challenging battle we we - -00:13:57.680 --> 00:14:00.480 -kind of aligned on some some principles - -00:14:00.480 --> 00:14:02.639 -that we wanted to adhere to - -00:14:02.639 --> 00:14:04.079 -once we started taking the project - -00:14:04.079 --> 00:14:05.680 -seriously - -00:14:05.680 --> 00:14:09.519 -like pre you know particularly - -00:14:09.519 --> 00:14:12.720 -recognizing gnu in specific as we focus - -00:14:12.720 --> 00:14:15.199 -on giving back to the community - -00:14:15.199 --> 00:14:16.480 -taking what we learned as pearl - -00:14:16.480 --> 00:14:18.240 -programmers and - -00:14:18.240 --> 00:14:22.079 -uh you know bringing that spirit forward - -00:14:22.079 --> 00:14:24.320 -into into our work and maybe - -00:14:24.320 --> 00:14:26.399 -specifically support making sure that we - -00:14:26.399 --> 00:14:27.120 -can - -00:14:27.120 --> 00:14:30.639 -um you know write uh functions for the - -00:14:30.639 --> 00:14:31.760 -game - -00:14:31.760 --> 00:14:35.199 -um in pearl if we want to - -00:14:35.199 --> 00:14:38.079 -and then to use the game as a vehicle to - -00:14:38.079 --> 00:14:40.320 -make people look beyond - -00:14:40.320 --> 00:14:43.360 -the - -00:14:43.360 --> 00:14:46.800 -typically open source or sorry typically - -00:14:46.800 --> 00:14:49.600 -uh nominally open source at best - -00:14:49.600 --> 00:14:52.160 -generally pretty closed world of - -00:14:52.160 --> 00:14:54.160 -computer gaming a lot of windows users - -00:14:54.160 --> 00:14:55.440 -out there a lot of free - -00:14:55.440 --> 00:14:57.519 -non-free communication tools and a lot - -00:14:57.519 --> 00:14:59.760 -of uh - -00:14:59.760 --> 00:15:01.839 -you know a lot of ground to cover from a - -00:15:01.839 --> 00:15:03.360 -free software perspective - -00:15:03.360 --> 00:15:05.920 -so what can Emacs do from a gaming - -00:15:05.920 --> 00:15:07.360 -standpoint to - -00:15:07.360 --> 00:15:12.160 -to open that up - -00:15:12.160 --> 00:15:14.880 -and not to mention the hubris of the you - -00:15:14.880 --> 00:15:16.720 -know the two of us with a few friends - -00:15:16.720 --> 00:15:18.399 -basically deciding to take on what - -00:15:18.399 --> 00:15:19.440 -amounts to a - -00:15:19.440 --> 00:15:21.839 -huge project um you know we're - -00:15:21.839 --> 00:15:24.720 -essentially a year in now and we haven't - -00:15:24.720 --> 00:15:27.839 -really gotten over halfway to our - -00:15:27.839 --> 00:15:30.000 -minimum playtestable candidate - -00:15:30.000 --> 00:15:32.880 -um it's a it's a work in progress we've - -00:15:32.880 --> 00:15:34.320 -got a long row to go - -00:15:34.320 --> 00:15:36.800 -there's at least 50 items on the things - -00:15:36.800 --> 00:15:38.399 -that we think are critical to - -00:15:38.399 --> 00:15:40.320 -to be able to introduce it to my younger - -00:15:40.320 --> 00:15:44.720 -kids for example - -00:15:44.720 --> 00:15:48.399 -um okay so we're in the accomplishments - -00:15:48.399 --> 00:15:49.279 -section - -00:15:49.279 --> 00:15:50.959 -so we're supposed to be talking about - -00:15:50.959 --> 00:15:52.639 -the things that we have - -00:15:52.639 --> 00:15:55.920 -succeeded in doing in our first year um - -00:15:55.920 --> 00:15:58.880 -we have succeeded in working with data - -00:15:58.880 --> 00:16:01.199 -in org documents using org mode - -00:16:01.199 --> 00:16:04.480 -tables to store the data that we're - -00:16:04.480 --> 00:16:05.360 -going to use - -00:16:05.360 --> 00:16:09.279 -in the various parts of our game - -00:16:09.279 --> 00:16:12.519 -um and we've had a lot of success with - -00:16:12.519 --> 00:16:14.160 -svg.el - -00:16:14.160 --> 00:16:16.639 -uh it started withdrawing maps and we - -00:16:16.639 --> 00:16:17.279 -have - -00:16:17.279 --> 00:16:19.440 -another talk about our mapping - -00:16:19.440 --> 00:16:21.440 -specifically coming up next so we'll - -00:16:21.440 --> 00:16:23.759 -put off some of that discussion for a - -00:16:23.759 --> 00:16:25.199 -separate talk - -00:16:25.199 --> 00:16:28.720 -um but we've also succeeded in - -00:16:28.720 --> 00:16:32.320 -um getting into a bunch of different - -00:16:32.320 --> 00:16:35.680 -elements of the game where uh - -00:16:35.680 --> 00:16:38.160 -we're you know making a lot of progress - -00:16:38.160 --> 00:16:38.959 -using this - -00:16:38.959 --> 00:16:41.920 -drawing engine we developed to also draw - -00:16:41.920 --> 00:16:43.759 -this other thing and also draw this - -00:16:43.759 --> 00:16:45.279 -other thing and also draw this other - -00:16:45.279 --> 00:16:46.079 -thing and it's - -00:16:46.079 --> 00:16:49.519 -um you know we kind of backed into - -00:16:49.519 --> 00:16:52.560 -we've got this aesthetic and we're - -00:16:52.560 --> 00:16:54.720 -using it to draw interfaces for all of - -00:16:54.720 --> 00:17:03.120 -the different parts of the game - -00:17:03.120 --> 00:17:05.600 -so let's talk let's talk a little bit - -00:17:05.600 --> 00:17:06.959 -about what - -00:17:06.959 --> 00:17:10.880 -uh what works now um - -00:17:10.880 --> 00:17:13.360 -first of all there's the mapping part - -00:17:13.360 --> 00:17:14.640 -that eric mentioned - -00:17:14.640 --> 00:17:18.480 -and we'll jump here into um we'll start - -00:17:18.480 --> 00:17:20.880 -opening up some files and looking around - -00:17:20.880 --> 00:17:22.160 -um but then - -00:17:22.160 --> 00:17:25.520 -also later uh we'll we'll fire up an eye - -00:17:25.520 --> 00:17:26.959 -elm and look at some of the - -00:17:26.959 --> 00:17:28.400 -some of the other proofs of concept so - -00:17:28.400 --> 00:17:30.240 -hopefully we can - -00:17:30.240 --> 00:17:32.240 -pivot the second talk more toward the - -00:17:32.240 --> 00:17:34.320 -demos as as we skip some of the - -00:17:34.320 --> 00:17:35.520 -interactive stuff that might be - -00:17:35.520 --> 00:17:43.200 -mentioned in the slides that we go by - -00:17:43.200 --> 00:17:46.880 -so maps - -00:17:46.880 --> 00:17:50.080 -visual battle board um - -00:17:50.080 --> 00:17:53.120 -the battle board I'm just gonna I'm just - -00:17:53.120 --> 00:17:54.160 -gonna skip it eric - -00:17:54.160 --> 00:18:02.000 -we'll hit it in the next one okay - -00:18:02.000 --> 00:18:08.480 -hang on - -00:18:08.480 --> 00:18:09.919 -okay so I'm just going to go ahead and - -00:18:09.919 --> 00:18:11.840 -open up uh maps and - -00:18:11.840 --> 00:18:13.760 -let you talk from the from the svg - -00:18:13.760 --> 00:18:15.039 -process itself - -00:18:15.039 --> 00:18:16.480 -because that's the interesting part to - -00:18:16.480 --> 00:18:22.240 -me that uh to me - -00:18:22.240 --> 00:18:26.080 -okay talk about the svg - -00:18:26.080 --> 00:18:28.640 -process like what what are you thinking - -00:18:28.640 --> 00:18:30.640 -exactly we want to talk about how - -00:18:30.640 --> 00:18:33.760 -we turn our data into an image or - -00:18:33.760 --> 00:18:37.919 -what what are you hoping for yeah so - -00:18:37.919 --> 00:18:39.760 -I mean did you did you want to talk more - -00:18:39.760 --> 00:18:41.200 -from from the - -00:18:41.200 --> 00:18:45.679 -svg the hand-drawn svg graphics at all - -00:18:45.679 --> 00:18:47.039 -I thought we were going to save that - -00:18:47.039 --> 00:18:49.760 -stuff for the passing talk okay - -00:18:49.760 --> 00:18:52.000 -right now if you want yeah I mean so - -00:18:52.000 --> 00:18:53.440 -we've got about - -00:18:53.440 --> 00:18:56.559 -uh 10 minutes before the turn where we - -00:18:56.559 --> 00:18:58.400 -thought we would first take any - -00:18:58.400 --> 00:19:00.400 -questions that are hanging out there - -00:19:00.400 --> 00:19:02.320 -I unfortunately closed the ether pad but - -00:19:02.320 --> 00:19:04.799 -I can open it again real quick - -00:19:04.799 --> 00:19:08.480 -and or you can jump - -00:19:08.480 --> 00:19:11.440 -jump into the to the pathing stuff now - -00:19:11.440 --> 00:19:12.320 -or I can just - -00:19:12.320 --> 00:19:13.760 -throw up an animal and we can start the - -00:19:13.760 --> 00:19:15.440 -demos so - -00:19:15.440 --> 00:19:18.880 -let me invite uh almond or sasha back in - -00:19:18.880 --> 00:19:19.840 -if you guys - -00:19:19.840 --> 00:19:22.160 -or leo if any of you want to join the - -00:19:22.160 --> 00:19:22.960 -conversation - -00:19:22.960 --> 00:19:25.840 -make a suggestion as to how we balance - -00:19:25.840 --> 00:19:27.120 -between the remaining time - -00:19:27.120 --> 00:19:29.840 -the rest of what we have left starts in - -00:19:29.840 --> 00:19:32.480 -on toward the technical so especially - -00:19:32.480 --> 00:19:35.120 -if there would be questions uh questions - -00:19:35.120 --> 00:19:36.840 -about the game right now that would be - -00:19:36.840 --> 00:19:40.160 -awesome - -00:19:40.160 --> 00:19:48.720 -and I'm gonna get seated again - -00:19:48.720 --> 00:19:51.200 -I'm not sure if I talk over the stream - -00:19:51.200 --> 00:19:53.200 -um if you'll hear it because I'm just - -00:19:53.200 --> 00:19:54.720 -watching your stream - -00:19:54.720 --> 00:20:01.200 -but I can try writing an irc um - -00:20:01.200 --> 00:20:04.640 -sure yeah questions would be cool um or - -00:20:04.640 --> 00:20:07.360 -um yeah well eric why don't you just go - -00:20:07.360 --> 00:20:08.559 -ahead and start walking us through the - -00:20:08.559 --> 00:20:09.120 -hand - -00:20:09.120 --> 00:20:11.440 -hand-drawn svg stuff just a little bit - -00:20:11.440 --> 00:20:12.960 -because I think - -00:20:12.960 --> 00:20:14.640 -if that isn't interesting to people we - -00:20:14.640 --> 00:20:17.120 -can just preempt for a question - -00:20:17.120 --> 00:20:21.120 -okay so historically when we - -00:20:21.120 --> 00:20:24.080 -um decided to actually start writing - -00:20:24.080 --> 00:20:25.840 -code one of the very first things we - -00:20:25.840 --> 00:20:26.720 -wanted to do - -00:20:26.720 --> 00:20:30.080 -was the maps because initially it seemed - -00:20:30.080 --> 00:20:31.919 -like the maps were going to be one of - -00:20:31.919 --> 00:20:33.840 -the biggest challenges - -00:20:33.840 --> 00:20:35.760 -in terms of how do we get a text editor - -00:20:35.760 --> 00:20:38.000 -to draw pictures for us - -00:20:38.000 --> 00:20:42.159 -um we pretty quickly decided we wanted - -00:20:42.159 --> 00:20:45.280 -to work with svgs because it allowed us - -00:20:45.280 --> 00:20:48.559 -to leverage the power of Emacs as a text - -00:20:48.559 --> 00:20:52.159 -editor and a text manipulator to write - -00:20:52.159 --> 00:20:56.080 -text graphics with the svg format - -00:20:56.080 --> 00:20:59.520 -so we did some svg graphics by hand - -00:20:59.520 --> 00:21:01.440 -we went in and just started hand coding - -00:21:01.440 --> 00:21:02.640 -things that looked - -00:21:02.640 --> 00:21:05.440 -visually like the maps we used to draw - -00:21:05.440 --> 00:21:07.440 -by hand on graph paper when - -00:21:07.440 --> 00:21:08.960 -we were you know sitting around the - -00:21:08.960 --> 00:21:11.360 -table - -00:21:11.360 --> 00:21:14.559 -yep absolutely what emerged from that - -00:21:14.559 --> 00:21:17.840 -is as we started working on um some of - -00:21:17.840 --> 00:21:20.400 -these files this particular image is a - -00:21:20.400 --> 00:21:24.000 -test of some 20 wide water - -00:21:24.000 --> 00:21:26.240 -with some beaches around it and a - -00:21:26.240 --> 00:21:28.000 -special chamber kind of off to the side - -00:21:28.000 --> 00:21:29.679 -called a clapper - -00:21:29.679 --> 00:21:33.760 -and this was the way we would code is by - -00:21:33.760 --> 00:21:36.559 -sketching by hand all of these things to - -00:21:36.559 --> 00:21:37.600 -look right - -00:21:37.600 --> 00:21:39.440 -and then we would take that code and we - -00:21:39.440 --> 00:21:42.080 -noticed um it became real repetitive - -00:21:42.080 --> 00:21:43.919 -as we would go like chunk of water chunk - -00:21:43.919 --> 00:21:45.440 -of water chunk of water - -00:21:45.440 --> 00:21:46.880 -and we're like okay so what we really - -00:21:46.880 --> 00:21:48.559 -need is to define a - -00:21:48.559 --> 00:21:52.000 -set of um we called it tiles um but like - -00:21:52.000 --> 00:21:53.600 -you could think of it as rubber stamps - -00:21:53.600 --> 00:21:55.760 -where we write this graphics code - -00:21:55.760 --> 00:21:57.440 -and then we're able to repeat it in - -00:21:57.440 --> 00:22:00.400 -different places around the map - -00:22:00.400 --> 00:22:03.039 -um you want to flip over to code view - -00:22:03.039 --> 00:22:07.120 -and show that or do we want to move into - -00:22:07.120 --> 00:22:10.240 -tiles code - -00:22:10.240 --> 00:22:12.720 -so you know you can see just really -

I will just add that if, if you're. -00:29:34.960 --> 00:29:36.399 -running a little bit +00:25:12.160 --> 00:25:15.570 +If one's passion as a dungeon master is killing player -00:29:36.399 --> 00:29:39.120 -we decided to do some experimentation +00:25:15.570 --> 00:25:19.210 +characters this game is meant for you. You don't have to -00:29:39.120 --> 00:29:42.480 -about seeing what we could do to push +00:25:19.210 --> 00:25:23.050 +build your game like that. But that's definitely a thing -00:29:42.480 --> 00:29:46.080 -the limits of our tile +00:25:23.050 --> 00:25:25.160 +that people do with this game. -00:29:46.080 --> 00:29:49.360 -and gender so we more or less on the +00:25:25.160 --> 00:25:28.430 +And then as Erik said, it just encourages you to put your -00:29:49.360 --> 00:29:50.080 -surface +00:25:28.430 --> 00:25:32.160 +creativity on the table to bring all the different elements. -00:29:50.080 --> 00:29:53.120 -map I +00:25:32.160 --> 00:25:35.830 +Hopefully, this may be clear in our slides since we were a -00:29:53.120 --> 00:29:56.399 -basically started with almost no +00:25:35.830 --> 00:25:39.430 +little fumbling for the first few minutes of the talk -00:29:56.399 --> 00:29:58.399 -tiles from below like the water and the +00:25:39.431 --> 00:25:44.160 +but there's also a kind of a player's guide that I started a few years ago. -00:29:58.399 --> 00:30:00.240 -beaches and the general store and the +00:25:44.160 --> 00:25:47.950 +That's not super complete, but does cover some -00:30:00.240 --> 00:30:01.279 -stairs +00:25:47.950 --> 00:25:52.160 +of the high level basics of the game that Erik's been talking from. -00:30:01.279 --> 00:30:03.679 -were existing tiles but then we were +00:25:52.160 --> 00:25:55.800 +And I would add that some of the things that you know some -00:30:03.679 --> 00:30:05.200 -like this is going to be a surface map +00:25:55.800 --> 00:25:58.890 +of what makes dungeon great is that there's a lot of -00:30:05.200 --> 00:30:07.279 -so we're outdoors so I want hills and I +00:25:58.890 --> 00:26:02.950 +mystery about it, like the player's handbook doesn't tell -00:30:07.279 --> 00:30:08.399 -want trees +00:26:02.950 --> 00:26:07.020 +you all of the rules, or like any really mystery and like -00:30:08.399 --> 00:30:11.760 -and I want grass and um it took a little +00:26:07.020 --> 00:26:09.160 +there's mazes and there's puzzles, -00:30:11.760 --> 00:30:12.399 -while +00:26:09.160 --> 00:26:12.650 +and you have to figure out how things work, and like we've -00:30:12.399 --> 00:30:15.039 -playing with svg to come up with some +00:26:12.650 --> 00:26:16.020 +got all of these treasure items in there that could help -00:30:15.039 --> 00:30:16.320 -acceptable code +00:26:16.020 --> 00:26:20.160 +you deal with a particular monster if it occurs to you to use it. -00:30:16.320 --> 00:30:18.480 -but once the like the grass gets tiled +00:26:20.160 --> 00:26:24.160 +And, you know, like that. There's a lot of. -00:30:18.480 --> 00:30:19.840 -out it +00:26:24.160 --> 00:26:27.450 +You don't know what's going on you're dropped in the middle -00:30:19.840 --> 00:30:21.600 -kind of you know gives the illusion of +00:26:27.450 --> 00:26:30.680 +of this situation and you have to try and survive and level -00:30:21.600 --> 00:30:23.039 -grass and +00:26:30.680 --> 00:26:33.750 +up and figure it out. And if you succeed in doing that for -00:30:23.039 --> 00:30:24.880 -you know these are all in my estimation +00:26:33.750 --> 00:26:36.520 +a long enough eventually you start realizing that there are -00:30:24.880 --> 00:30:26.399 -kind of crude graphics +00:26:36.520 --> 00:26:40.890 +big picture puzzles that there are, you know, there is more to this than just -00:30:26.399 --> 00:30:28.640 -but we're at the proof of concept stage +00:26:40.890 --> 00:26:43.160 +killing things and taking their stuff. -00:30:28.640 --> 00:30:30.399 -and it definitely proves that we can use +00:26:43.160 --> 00:26:46.190 +And that's where the joy of designing these games comes in -00:30:30.399 --> 00:30:31.679 -our graphics engine +00:26:46.190 --> 00:26:48.890 +for me is like designing the mazes and designing the -00:30:31.679 --> 00:30:34.640 -to decide what we want our maps to look +00:26:48.890 --> 00:26:51.890 +puzzles and like, oh yeah and then they're going to come -00:30:34.640 --> 00:30:35.279 -like +00:26:51.890 --> 00:26:51.890 +out of this room and you know what they're going to do. -00:30:35.279 --> 00:30:39.440 -and real quickly compose new map tiles +00:26:51.891 --> 00:26:57.160 +They're wanting to go that way. -00:30:39.440 --> 00:30:44.240 -and uh stamp out a bunch of new maps +00:26:57.160 --> 00:27:00.160 +So I'm going to put the trap right there. -00:30:44.240 --> 00:30:46.880 -so now I'll uh show off one of the other +00:27:00.160 --> 00:27:00.160 +And I walk right into it every time. -00:30:46.880 --> 00:30:48.640 -things so the next thing we did once we +00:27:00.161 --> 00:27:00.161 +And then when the party does get in your map -00:30:48.640 --> 00:30:50.559 -once we had the maps doing +00:27:00.162 --> 00:27:00.162 +and they do exactly what you thought and they hit the trap -00:30:50.559 --> 00:30:51.919 -and we haven't gotten into the features +00:27:00.163 --> 00:27:07.820 +it's just really satisfying -00:30:51.919 --> 00:30:53.600 -of the maps we can we can appoint time +00:27:07.820 --> 00:27:07.820 +to watch the look on their little faces -00:30:53.600 --> 00:30:54.960 -to that or not +00:27:07.821 --> 00:27:12.160 +as they squirm and struggle to stay alive. -00:30:54.960 --> 00:30:58.960 -but um there are a number of +00:27:12.160 --> 00:27:14.580 +Yeah, that's, that's what I was trying to get at. Thanks. -00:30:58.960 --> 00:31:00.720 -uh featured features there that we can +00:27:14.580 --> 00:27:18.160 +All right, that was perfect for me. All right. -00:31:00.720 --> 00:31:02.840 -look at the +00:27:18.160 --> 00:27:21.360 +So so highlight your question for me if you think it's -00:31:02.840 --> 00:31:05.760 -uh we then wanted to +00:27:21.360 --> 00:27:24.800 +important we grab it here before we jump into demos, -00:31:05.760 --> 00:31:08.640 -try to see if that could make other +00:27:24.801 --> 00:27:28.160 +but otherwise I think it's time to try running some code. -00:31:08.640 --> 00:31:10.399 -interfaces more appealing so we built +00:27:28.160 --> 00:27:30.160 +Let's say. -00:31:10.399 --> 00:31:11.360 -stuff like +00:27:30.160 --> 00:27:37.160 +Okay, I say do it.

All right, I'm not sure what's -00:36:10.640 --> 00:36:11.040 -draw +00:35:12.360 --> 00:35:14.160 +up with the battle board Erik. -00:36:11.040 --> 00:36:14.880 -engine using um all of the same things +00:35:14.160 --> 00:35:17.190 +We haven't messed with that one for a while in fact we had -00:36:14.880 --> 00:36:19.599 -let's see that's selected so +00:35:17.190 --> 00:35:20.270 +discussed using its code as an example so maybe we'll debug -00:36:19.599 --> 00:36:21.680 -uh we'll just try bringing up a map +00:35:20.270 --> 00:35:21.160 +it with you. -00:36:21.680 --> 00:36:23.119 -again +00:35:21.160 --> 00:35:24.160 +I'll certainly check for questions first. -00:36:23.119 --> 00:36:26.320 -there's one and you'll notice um dm +00:35:24.160 --> 00:35:29.740 +Um, the. So the character sheet which is not scaling -00:36:26.320 --> 00:36:28.560 -map doesn't know anything about the new +00:35:29.740 --> 00:35:31.160 +ideally here. -00:36:28.560 --> 00:36:29.839 -draw engine +00:35:31.160 --> 00:35:36.160 +See if reloading it does anything. -00:36:29.839 --> 00:36:31.599 -and there are a couple of places where +00:35:36.160 --> 00:35:37.160 +Nope. -00:36:31.599 --> 00:36:33.520 -the new draw engine is still +00:35:37.160 --> 00:35:40.660 +As far as I can tell, assuming you don't have this -00:36:33.520 --> 00:36:36.480 -hooked in to the s for example +00:35:40.660 --> 00:35:43.160 +implemented character sheet. -00:36:36.480 --> 00:36:37.440 -particularly +00:35:43.160 --> 00:35:49.800 +That's right, there's everything in scale, it take in order -00:36:37.440 --> 00:36:39.680 -the sizing of the graph paper background +00:35:49.800 --> 00:35:54.160 +to get what you were looking at there. -00:36:39.680 --> 00:36:41.119 -so I've started the work +00:35:54.160 --> 00:35:56.160 +All right. -00:36:41.119 --> 00:36:44.240 -in dmdraw.el +00:35:56.160 --> 00:36:03.201 +This, this whole thing is hard coded, basically to the -00:36:44.240 --> 00:36:47.040 -of trying to show how exactly we did +00:36:03.202 --> 00:36:08.160 +gills, except for things like this. -00:36:47.040 --> 00:36:47.440 -this +00:36:08.160 --> 00:36:11.780 +This program represents a re implementation of the drawing -00:36:47.440 --> 00:36:50.160 -removing the how did we get data out of +00:36:11.780 --> 00:36:17.420 +engine using all of the same things. Let's see that -00:36:50.160 --> 00:36:51.760 -org mode that I talked about yesterday +00:36:17.420 --> 00:36:20.160 +selected so -00:36:51.760 --> 00:36:53.280 -with our etl flows +00:36:20.160 --> 00:36:23.160 +we'll just try bringing up a map again. -00:36:53.280 --> 00:36:56.480 -and just focusing on +00:36:23.160 --> 00:36:27.180 +There's one and you'll notice DM map doesn't know anything -00:36:56.480 --> 00:36:58.960 -how did we solve the problem of +00:36:27.180 --> 00:36:31.240 +about the new draw engine, and there are a couple of places -00:36:58.960 --> 00:37:00.160 -predicated drawing +00:36:31.240 --> 00:36:35.160 +where the new draw engine is still hooked in to the. -00:37:00.160 --> 00:37:01.839 -which I realized we didn't really talk +00:36:35.160 --> 00:36:38.250 +For example, particularly the sizing of the graph paper -00:37:01.839 --> 00:37:05.200 -about so should I jump into that +00:36:38.250 --> 00:36:43.160 +background. So I've started the work in DM draw. -00:37:05.200 --> 00:37:07.760 -yeah I guess uh how are we on time we +00:36:44.160 --> 00:36:47.950 +Of trying to show how exactly we did this removing the, how -00:37:07.760 --> 00:37:09.280 -have time for detours +00:36:47.950 --> 00:36:51.040 +did we get data out of org mode that I talked about -00:37:09.280 --> 00:37:11.359 -um yeah it looks like we could spend two +00:36:51.040 --> 00:36:56.410 +yesterday with our ETL flows, and just focusing on what how -00:37:11.359 --> 00:37:12.800 -or three minutes on that and then +00:36:56.410 --> 00:37:00.580 +did we solve the problem of predicated drawing, which I -00:37:12.800 --> 00:37:15.599 -uh come back for the questions cool do +00:37:00.580 --> 00:37:04.290 +realized we didn't really talk about so should I jump into -00:37:15.599 --> 00:37:17.680 -it +00:37:04.290 --> 00:37:05.160 +that. -00:37:17.680 --> 00:37:20.480 -and I'm just gonna peek into my org mode +00:37:05.160 --> 00:37:06.160 +Yeah, I guess. -00:37:20.480 --> 00:37:20.800 -by +00:37:06.160 --> 00:37:09.160 +How are we on time, we have time for detours. -00:37:20.800 --> 00:37:23.200 -into my chat conference and I don't see +00:37:09.160 --> 00:37:12.450 +Um, yeah, it looks like we could spend two or three minutes -00:37:23.200 --> 00:37:24.960 -anybody talking to me from the organizer +00:37:12.450 --> 00:37:15.160 +on that and then come back for the questions. -00:37:24.960 --> 00:37:25.520 -channel +00:37:15.160 --> 00:37:18.160 +Cool. -00:37:25.520 --> 00:37:26.560 -so I'm going to assume that's a good +00:37:18.160 --> 00:37:21.440 +And I'm just going to peek into my org mode into my chat -00:37:26.560 --> 00:37:28.800 -guess +00:37:21.440 --> 00:37:24.970 +conference and I don't see anybody talking to me from the -00:37:28.800 --> 00:37:32.079 -um all right so let's let's go ahead and +00:37:24.970 --> 00:37:29.160 +organizer channel, so I'm gonna assume that's a good guess. -00:37:32.079 --> 00:37:34.160 -play with the map a little then that is +00:37:29.160 --> 00:37:33.700 +All right, so let's go ahead and play with the map a -00:37:34.160 --> 00:37:37.760 -uh pretty fun and and uh so much fun +00:37:33.700 --> 00:37:38.170 +little then that is pretty fun and so much fun that we -00:37:37.760 --> 00:37:39.440 -that we had to curtail play sessions in +00:37:38.170 --> 00:37:42.640 +had to curtail play sessions in order to keep working on -00:37:39.440 --> 00:37:41.760 -order to keep working on the project +00:37:42.640 --> 00:37:44.160 +the project. -00:37:41.760 --> 00:37:45.119 -um +00:37:44.160 --> 00:37:52.160 +So, I'll, I'll do the. -00:37:45.119 --> 00:37:48.480 -so uh I'll +00:37:52.160 --> 00:37:58.516 +Um, we'll try to find something different from any gift -00:37:48.480 --> 00:37:51.839 -I'll do the +00:37:58.517 --> 00:38:01.160 +I've shared here right. -00:37:51.839 --> 00:37:55.920 -um we'll try to find something different +00:38:01.160 --> 00:38:06.160 +So here we are in a random. Go ahead, Erik, you feel. -00:37:55.920 --> 00:38:01.040 -from any gif I've shared here right +00:38:06.160 --> 00:38:10.660 +Okay, so what we're, what Corwin is doing here is he's -00:38:01.040 --> 00:38:03.359 -so here we are in a random go ahead eric +00:38:10.660 --> 00:38:15.380 +about to put the map into play mode, which is going to turn -00:38:03.359 --> 00:38:05.760 -you phil +00:38:15.380 --> 00:38:17.160 +on the fog of war. -00:38:05.760 --> 00:38:08.240 -oh okay so what what what corwin is +00:38:17.160 --> 00:38:21.100 +And then we're going to use the fog of war and the, the -00:38:08.240 --> 00:38:10.000 -doing here is he's about to put the +00:38:21.100 --> 00:38:25.230 +play mode to kind of reveal the map, one square at a time -00:38:10.000 --> 00:38:13.359 -the map into play mode um +00:38:25.230 --> 00:38:28.160 +like we would during a play session. -00:38:13.359 --> 00:38:16.800 -which is going to turn on the fog of war +00:38:28.160 --> 00:38:32.350 +So we'll just drop the party randomly somewhere onto this -00:38:16.800 --> 00:38:19.920 -and then we're gonna use +00:38:32.350 --> 00:38:36.160 +map looks like we're on alpha maze level three here. -00:38:19.920 --> 00:38:23.040 -the fog of war and the the play mode to +00:38:36.160 --> 00:38:46.160 +And then we'll walk around a little. -00:38:23.040 --> 00:38:24.560 -kind of reveal the map +00:38:46.160 --> 00:38:52.280 +Okay, so we're halfway there. I'll have to, I'll have to do -00:38:24.560 --> 00:38:26.240 -one square at a time like we would +00:38:52.280 --> 00:38:55.540 +a full redraw the sketch the sketching stuff has has has -00:38:26.240 --> 00:38:28.160 -during a play session +00:38:55.540 --> 00:38:58.980 +broken things here like I said, the two aren't separated -00:38:28.160 --> 00:38:29.920 -so we'll just drop the party randomly +00:38:58.980 --> 00:39:01.910 +once I run them in the same instance, they're not -00:38:29.920 --> 00:38:31.280 -somewhere onto this map +00:39:01.910 --> 00:39:03.160 +predictable. -00:38:31.280 --> 00:38:33.839 -looks like we're on alpha maze level +00:39:03.160 --> 00:39:08.060 +Okay, so let me elaborate here when he says the sketching -00:38:33.839 --> 00:38:36.079 -three here +00:39:08.060 --> 00:39:12.960 +stuff. The current focus of our work is to turn all of this -00:38:36.079 --> 00:38:40.800 -and um +00:39:12.960 --> 00:39:17.940 +map stuff we've got into a basically a WYSIWYG map editor, -00:38:40.800 --> 00:38:46.320 -uh-oh then we'll walk around a little +00:39:17.940 --> 00:39:22.330 +where we can get into the tiles, and we'll be able to -00:38:46.320 --> 00:38:50.480 -okay there we go we're halfway there - -00:38:50.480 --> 00:38:52.160 -I'll have to I'll have to do a full - -00:38:52.160 --> 00:38:53.520 -redraw - -00:38:53.520 --> 00:38:55.920 -uh the sketch the sketching stuff has - -00:38:55.920 --> 00:38:58.480 -has has broken things here like I said - -00:38:58.480 --> 00:39:00.240 -the two aren't separated once I run them - -00:39:00.240 --> 00:39:01.599 -in the same instance they're not - -00:39:01.599 --> 00:39:03.520 -predictable - -00:39:03.520 --> 00:39:05.359 -okay so let me elaborate here when he - -00:39:05.359 --> 00:39:07.040 -says the sketching stuff - -00:39:07.040 --> 00:39:10.560 -the current um focus of our work is to - -00:39:10.560 --> 00:39:13.520 -turn all of this map stuff we've got - -00:39:13.520 --> 00:39:14.320 -into - -00:39:14.320 --> 00:39:17.920 -a basically a wysiwyg map editor - -00:39:17.920 --> 00:39:20.880 -where we can get into the tiles and - -00:39:20.880 --> 00:39:22.160 -we'll be able to - -00:39:22.160 --> 00:39:24.480 +00:39:22.330 --> 00:39:24.160 select the tile and basically rubber -00:39:24.480 --> 00:39:26.560 -stamp it into a map - -00:39:26.560 --> 00:39:29.680 -graphically and then save the map file - -00:39:29.680 --> 00:39:30.000 -out - -00:39:30.000 --> 00:39:33.280 -and load it back in later so that um - -00:39:33.280 --> 00:39:36.720 -we're able to you know just pound out - -00:39:36.720 --> 00:39:38.480 -these maps real fast - -00:39:38.480 --> 00:39:42.000 -um using a graphical editor rather than - -00:39:42.000 --> 00:39:43.200 -having to hand code - -00:39:43.200 --> 00:39:45.440 -every symbol and every square of the - -00:39:45.440 --> 00:39:48.000 -tables - -00:39:48.000 --> 00:39:52.960 -so the process of doing that um - -00:39:52.960 --> 00:39:54.800 -things are a mess we've got covers off - -00:39:54.800 --> 00:39:56.720 -there's wires hanging out - -00:39:56.720 --> 00:39:58.720 -um different stuff works on different - -00:39:58.720 --> 00:40:03.119 -days - -00:40:03.119 --> 00:40:05.200 -well I will say in our defense this is - -00:40:05.200 --> 00:40:07.119 -exactly why we staged a complicated - -00:40:07.119 --> 00:40:07.520 -thing - -00:40:07.520 --> 00:40:09.680 -and uh probably we should have just gone - -00:40:09.680 --> 00:40:11.119 -with that instead of - -00:40:11.119 --> 00:40:14.160 -trying to give you uh the experience - -00:40:14.160 --> 00:40:17.760 -of of of what it's like uh to use Emacs - -00:40:17.760 --> 00:40:19.200 -to do this which is - -00:40:19.200 --> 00:40:21.359 -which is sort of the last minute thought - -00:40:21.359 --> 00:40:23.280 -there and my apologies for that - -00:40:23.280 --> 00:40:25.119 -if that's made it harder to follow the - -00:40:25.119 --> 00:40:27.200 -thread let's check back now for - -00:40:27.200 --> 00:40:28.240 -questions - -00:40:28.240 --> 00:40:30.000 -and see if anybody wants to redirect at - -00:40:30.000 --> 00:40:36.640 -all - -00:40:36.640 --> 00:40:39.599 -so yep this so what you're looking at - -00:40:39.599 --> 00:40:40.800 -all uses prog - -00:40:40.800 --> 00:40:44.880 -pragmatic svg uh - -00:40:44.880 --> 00:40:47.760 -svg generation uh for question number - -00:40:47.760 --> 00:40:49.119 -four there have you played with - -00:40:49.119 --> 00:40:52.000 -generating svgs pragmatically in Emacs - -00:40:52.000 --> 00:40:55.119 -that is what the maps are doing um in - -00:40:55.119 --> 00:40:55.680 -terms - -00:40:55.680 --> 00:40:58.480 -of uh uh we should have been maybe more - -00:40:58.480 --> 00:41:00.400 -explicit about that we started hand - -00:41:00.400 --> 00:41:01.680 -coding things and - -00:41:01.680 --> 00:41:05.119 -once we got the idea of what the code - -00:41:05.119 --> 00:41:06.400 -was going to look like - -00:41:06.400 --> 00:41:09.359 -we switched to doing it programmatically - -00:41:09.359 --> 00:41:10.000 -so - -00:41:10.000 --> 00:41:12.880 -um we were going to open up maybe now if - -00:41:12.880 --> 00:41:14.640 -we've got time we can get into the tile - -00:41:14.640 --> 00:41:15.839 -set real quick - -00:41:15.839 --> 00:41:18.640 -sure we definitely didn't do any of the - -00:41:18.640 --> 00:41:20.560 -pathing slides and so now we've skipped - -00:41:20.560 --> 00:41:23.040 -over some stuff we were going to present - -00:41:23.040 --> 00:41:25.040 -yeah that's right we skipped a whole - -00:41:25.040 --> 00:41:26.880 -bunch of slides and I can certainly uh - -00:41:26.880 --> 00:41:28.160 -go back to them they're open here - -00:41:28.160 --> 00:41:31.040 -obviously - -00:41:31.040 --> 00:41:33.599 -um right I was just showing off the - -00:41:33.599 --> 00:41:34.480 -sketching - -00:41:34.480 --> 00:41:36.880 -tool uh briefly in that context but I - -00:41:36.880 --> 00:41:38.000 -think you're right let's - -00:41:38.000 --> 00:41:40.000 -we can jump over to the actually I - -00:41:40.000 --> 00:41:41.280 -should finish with this now having - -00:41:41.280 --> 00:41:42.000 -teased it - -00:41:42.000 --> 00:41:45.119 -so let's do the same thing here ctrl h m - -00:41:45.119 --> 00:41:47.119 -and you'll see in this case there are - -00:41:47.119 --> 00:41:48.560 -very few keyboard - -00:41:48.560 --> 00:41:52.160 -key bindings that are set up um even - -00:41:52.160 --> 00:41:55.359 -this uh shift delete has a tera uh - -00:41:55.359 --> 00:41:59.280 -or shift with uh - -00:41:59.280 --> 00:42:02.560 -yeah control delete it would seem to be - -00:42:02.560 --> 00:42:05.680 -so that has couple obvious bugs with it - -00:42:05.680 --> 00:42:07.119 -right didn't pick it didn't pick up - -00:42:07.119 --> 00:42:09.280 -those control points until I reused them - -00:42:09.280 --> 00:42:11.280 -not clearing that stack - -00:42:11.280 --> 00:42:13.760 -um and also should probably think about - -00:42:13.760 --> 00:42:14.480 -whether - -00:42:14.480 --> 00:42:16.720 -the origin should return and hey marking - -00:42:16.720 --> 00:42:18.400 -that origin would be nice - -00:42:18.400 --> 00:42:19.839 -so there's a tremendous amount to do - -00:42:19.839 --> 00:42:21.680 -here this is just uh - -00:42:21.680 --> 00:42:24.400 -showing that it is possible to use - -00:42:24.400 --> 00:42:26.079 -essentially like a touch input - -00:42:26.079 --> 00:42:31.680 -to um uh - -00:42:31.680 --> 00:42:35.119 -yeah and then also we can switch over to - -00:42:35.119 --> 00:42:35.760 -our place - -00:42:35.760 --> 00:42:39.040 -tool and - -00:42:39.040 --> 00:42:43.040 -um hopefully we can get a nice big menu - -00:42:43.040 --> 00:42:45.040 -of all the tiles that eric prepared for - -00:42:45.040 --> 00:42:49.440 -the game maps - -00:42:49.440 --> 00:42:51.680 -uh that was probably a terrible choice - -00:42:51.680 --> 00:42:53.119 -but there you have just a bit of - -00:42:53.119 --> 00:42:56.800 -corridor right - -00:42:56.800 --> 00:43:00.480 -that looks - -00:43:00.480 --> 00:43:04.560 -uh and even the click yep and this this - -00:43:04.560 --> 00:43:06.160 -glitch action here is the last thing I - -00:43:06.160 --> 00:43:07.280 -was working on before I dropped - -00:43:07.280 --> 00:43:08.079 -everything to - -00:43:08.079 --> 00:43:10.079 -to build the decks that uh we will soon - -00:43:10.079 --> 00:43:14.240 -share for this conference - -00:43:14.240 --> 00:43:19.680 -so okay back to the tile sets - -00:43:19.680 --> 00:43:22.160 -right so the way we approached drawing - -00:43:22.160 --> 00:43:23.440 -it programmatically - -00:43:23.440 --> 00:43:25.200 -is we broke our code up into little - -00:43:25.200 --> 00:43:27.280 -snippets we called tiles - -00:43:27.280 --> 00:43:29.280 -um corman's going to open up the tile - -00:43:29.280 --> 00:43:32.160 -set here basically each tile has a name - -00:43:32.160 --> 00:43:35.280 -and then with that name we place data - -00:43:35.280 --> 00:43:37.920 -into different layers of the image - -00:43:37.920 --> 00:43:40.640 -some of the layers are just svg paths - -00:43:40.640 --> 00:43:41.280 -and - -00:43:41.280 --> 00:43:44.880 -the data is just svg commands - -00:43:44.880 --> 00:43:47.920 -like we saw in that handwritten code and - -00:43:47.920 --> 00:43:50.960 -some of it is compositions of other - -00:43:50.960 --> 00:43:54.160 -tiles so a tile can be made up of other - -00:43:54.160 --> 00:43:56.160 -tiles - -00:43:56.160 --> 00:43:58.000 -furthermore some of these tiles have - -00:43:58.000 --> 00:43:59.599 -conditional code in it - -00:43:59.599 --> 00:44:02.319 -where like some of this stuff is talking - -00:44:02.319 --> 00:44:02.720 -about - -00:44:02.720 --> 00:44:06.560 -elf and bang elf so the map is going to - -00:44:06.560 --> 00:44:08.079 -be drawn differently depending - -00:44:08.079 --> 00:44:09.440 -on whether or not there's elves in the - -00:44:09.440 --> 00:44:11.200 -party - -00:44:11.200 --> 00:44:16.880 -um so and that's the demo they broke - -00:44:16.880 --> 00:44:18.240 -the engine has to make all those - -00:44:18.240 --> 00:44:20.000 -decisions um - -00:44:20.000 --> 00:44:21.599 -and that's what we're calling predicated - -00:44:21.599 --> 00:44:23.280 -drawing oh there's a - -00:44:23.280 --> 00:44:25.200 -special room here do you have any elves - -00:44:25.200 --> 00:44:26.480 -you do so I draw - -00:44:26.480 --> 00:44:32.880 -there is elf's way um - -00:44:32.880 --> 00:44:35.839 -yeah so we built up the set of tiles and - -00:44:35.839 --> 00:44:36.319 -then - -00:44:36.319 --> 00:44:39.920 -um we basically made map files which - -00:44:39.920 --> 00:44:43.760 -take um our map and break it up into xy - -00:44:43.760 --> 00:44:47.839 -grids and then we drop these tiles into - -00:44:47.839 --> 00:44:50.240 -positions on the map so we can use the - -00:44:50.240 --> 00:44:52.000 -same tile square after square after - -00:44:52.000 --> 00:44:52.480 -square - -00:44:52.480 --> 00:44:54.720 -when there's a corridor north south it's - -00:44:54.720 --> 00:44:55.680 -the same tile - -00:44:55.680 --> 00:44:59.119 -over and over again and that makes it - -00:44:59.119 --> 00:45:02.400 -easy to reuse the code and then also - -00:45:02.400 --> 00:45:05.920 -when uh - -00:45:05.920 --> 00:45:10.560 -when we go to present um the - -00:45:10.560 --> 00:45:13.520 -what am I trying to say the the drawing - -00:45:13.520 --> 00:45:15.839 -in in fog of war mode as we move down - -00:45:15.839 --> 00:45:18.000 -the corridor we can just add the - -00:45:18.000 --> 00:45:20.640 -necessary code one bit at a time to the - -00:45:20.640 --> 00:45:23.440 -visible image so that what we're - -00:45:23.440 --> 00:45:24.960 -displaying doesn't contain - -00:45:24.960 --> 00:45:27.359 -any data except what the party has - -00:45:27.359 --> 00:45:30.240 -already discovered - -00:45:30.240 --> 00:45:32.319 -and thus we have kind of spoiler rich - -00:45:32.319 --> 00:45:34.400 -documents sitting on the gm - -00:45:34.400 --> 00:45:37.359 -server and then less you know and - -00:45:37.359 --> 00:45:38.400 -spoiler-free - -00:45:38.400 --> 00:45:41.440 -data that flows down to the org mode uh - -00:45:41.440 --> 00:45:44.000 -files on the player system and the only - -00:45:44.000 --> 00:45:47.040 -real challenge is making sure that the - -00:45:47.040 --> 00:45:50.160 -the nothing that the game does can mess - -00:45:50.160 --> 00:45:50.960 -with the - -00:45:50.960 --> 00:45:54.480 -the the users the the players data file - -00:45:54.480 --> 00:45:55.280 -in case they - -00:45:55.280 --> 00:45:57.680 -might have their own notes and things in - -00:45:57.680 --> 00:46:00.160 -it that that would be the one - -00:46:00.160 --> 00:46:06.160 -uh you know number one thing to avoid - -00:46:06.160 --> 00:46:08.000 -another thing we can talk about here is - -00:46:08.000 --> 00:46:09.680 -that there are layers - -00:46:09.680 --> 00:46:11.839 -you can see this table at the bottom has - -00:46:11.839 --> 00:46:13.520 -tile and overlay - -00:46:13.520 --> 00:46:15.119 -the overlay column is just going to - -00:46:15.119 --> 00:46:17.040 -contain some actual svg - -00:46:17.040 --> 00:46:20.800 -xml style tags um so that's where we can - -00:46:20.800 --> 00:46:21.599 -add whatever - -00:46:21.599 --> 00:46:25.359 -text elements or other svg like raw svg - -00:46:25.359 --> 00:46:26.720 -tags we want - -00:46:26.720 --> 00:46:28.880 -whereas a lot of the other layers are - -00:46:28.880 --> 00:46:30.560 -going to be like path layers we've got - -00:46:30.560 --> 00:46:32.960 -water layers and beach layers - -00:46:32.960 --> 00:46:35.359 -and our plan was to have a style sheet - -00:46:35.359 --> 00:46:37.680 -that defines how each of those layers - -00:46:37.680 --> 00:46:38.720 -are represented - -00:46:38.720 --> 00:46:40.720 -so like when the water gets drawn blue - -00:46:40.720 --> 00:46:42.160 -and it's got arrows on it - -00:46:42.160 --> 00:46:45.520 -giving it direction um all of that - -00:46:45.520 --> 00:46:47.680 -can be customized with a style sheet to - -00:46:47.680 --> 00:46:49.200 -change the water to be - -00:46:49.200 --> 00:46:51.200 -whatever you want and like we have - -00:46:51.200 --> 00:46:52.960 -beaches as yellow but maybe you like - -00:46:52.960 --> 00:46:54.319 -beaches as red or - -00:46:54.319 --> 00:46:57.359 -you know whatever so we also built - -00:46:57.359 --> 00:47:01.200 -some test programs um - -00:47:01.200 --> 00:47:04.079 -and various of the I'm not not sure what - -00:47:04.079 --> 00:47:05.359 -kind of shape we're gonna find these in - -00:47:05.359 --> 00:47:07.040 -but we can try running them - -00:47:07.040 --> 00:47:10.640 -um here for example is just a - -00:47:10.640 --> 00:47:12.960 -very basic all of using a saint using - -00:47:12.960 --> 00:47:15.119 -the same file to define - -00:47:15.119 --> 00:47:18.560 -the tiles and and then - -00:47:18.560 --> 00:47:24.880 -the layout so to speak oh look at that - -00:47:24.880 --> 00:47:26.640 -uh there's the layout okay so that - -00:47:26.640 --> 00:47:28.960 -actually looks fine tile - -00:47:28.960 --> 00:47:30.960 -and it's pat so this is defining a tile - -00:47:30.960 --> 00:47:32.400 -named seas - -00:47:32.400 --> 00:47:35.440 -and uh it's gonna have a list of tiles - -00:47:35.440 --> 00:47:38.720 -defined above um and you'll notice also - -00:47:38.720 --> 00:47:41.839 -that we can just sort of freely define - -00:47:41.839 --> 00:47:44.559 -and redefine and it sort of figures out - -00:47:44.559 --> 00:47:46.160 -oh this must still be part of the b - -00:47:46.160 --> 00:47:50.839 -row um we could also have done - -00:47:50.839 --> 00:48:00.000 -this - -00:48:00.000 --> 00:48:02.160 -okay so this would this would work as - -00:48:02.160 --> 00:48:08.480 -would this - -00:48:08.480 --> 00:48:11.599 -one of uh early on in development when - -00:48:11.599 --> 00:48:12.720 -we were talking about - -00:48:12.720 --> 00:48:14.400 -getting data in and out of these org - -00:48:14.400 --> 00:48:15.839 -tables it - -00:48:15.839 --> 00:48:19.440 -was kind of a priority to us to - -00:48:19.440 --> 00:48:22.319 -leave the way the data is organized open - -00:48:22.319 --> 00:48:23.040 -to - -00:48:23.040 --> 00:48:26.960 -the users and to the dungeon masters so - -00:48:26.960 --> 00:48:30.720 -while we set our tile set apart from our - -00:48:30.720 --> 00:48:32.559 -map sets - -00:48:32.559 --> 00:48:35.440 -this clearly shows that you can cram a - -00:48:35.440 --> 00:48:38.319 -tile set and a map into a single file - -00:48:38.319 --> 00:48:41.040 -so in situations like the surface where - -00:48:41.040 --> 00:48:43.040 -we're using different tiles from other - -00:48:43.040 --> 00:48:43.760 -maps - -00:48:43.760 --> 00:48:46.559 -maybe it makes sense to move you know - -00:48:46.559 --> 00:48:48.079 -those tiles just into the file - -00:48:48.079 --> 00:48:50.559 -with your map or like it's hard for us - -00:48:50.559 --> 00:48:52.400 -to predict how other people are going to - -00:48:52.400 --> 00:48:54.319 -want to use this when they design their - -00:48:54.319 --> 00:48:55.119 -games - -00:48:55.119 --> 00:48:57.359 -so we wanted to leave it as versatile as - -00:48:57.359 --> 00:48:58.160 -possible - -00:48:58.160 --> 00:49:01.599 -about how you can use it where it - -00:49:01.599 --> 00:49:02.640 -matters right - -00:49:02.640 --> 00:49:04.319 -not support every feature in the world I - -00:49:04.319 --> 00:49:05.920 -can't count the number of times I said - -00:49:05.920 --> 00:49:07.280 -eric eric eric - -00:49:07.280 --> 00:49:09.200 -hey if we do it like this people will be - -00:49:09.200 --> 00:49:10.800 -able and he just like - -00:49:10.800 --> 00:49:14.000 -does it have to do that do we do we does - -00:49:14.000 --> 00:49:14.480 -it like - -00:49:14.480 --> 00:49:17.920 -do we need it right away uh - -00:49:17.920 --> 00:49:19.599 -do you have to really rewrite everything - -00:49:19.599 --> 00:49:21.040 -so it can all do that - -00:49:21.040 --> 00:49:24.160 -and uh a lot of those - -00:49:24.160 --> 00:49:26.880 -a lot of those conversations too but the - -00:49:26.880 --> 00:49:28.240 -the key flexibilities - -00:49:28.240 --> 00:49:31.200 -are really there people might want to - -00:49:31.200 --> 00:49:32.559 -use a lot of different files they might - -00:49:32.559 --> 00:49:34.160 -want to lay the tables out however they - -00:49:34.160 --> 00:49:35.760 -want they have to be able to say hey - -00:49:35.760 --> 00:49:37.440 -this is a table that has - -00:49:37.440 --> 00:49:39.440 -data that's controlled by the game and - -00:49:39.440 --> 00:49:40.720 -everything else in the file - -00:49:40.720 --> 00:49:44.079 -is not the game's problem - -00:49:44.079 --> 00:49:45.920 -on our table some of our tables started - -00:49:45.920 --> 00:49:47.440 -getting really wide so we started - -00:49:47.440 --> 00:49:48.960 -striping the tables - -00:49:48.960 --> 00:49:51.119 -where we'll repeat the same table over - -00:49:51.119 --> 00:49:52.640 -and over and over again to - -00:49:52.640 --> 00:49:56.400 -get all of the columns in there without - -00:49:56.400 --> 00:49:59.119 -making it you know a million miles wide - -00:49:59.119 --> 00:49:59.599 -yeah - -00:49:59.599 --> 00:50:01.040 -do you want to should I go ahead and - -00:50:01.040 --> 00:50:02.640 -pull open like a level here - -00:50:02.640 --> 00:50:06.079 -do you think sure just to have shown it - -00:50:06.079 --> 00:50:08.319 -the aisle set's a great example of - -00:50:08.319 --> 00:50:09.680 -striped tables if you - -00:50:09.680 --> 00:50:11.119 -look down like in the level change - -00:50:11.119 --> 00:50:18.800 -feature oh sure - -00:50:18.800 --> 00:50:20.240 -sorry I'm not quite sitting well to my - -00:50:20.240 --> 00:50:22.400 -keyboard here I can just readjust things - -00:50:22.400 --> 00:50:30.079 -real quick - -00:50:30.079 --> 00:50:33.280 -so what you know you can see here - -00:50:33.280 --> 00:50:35.200 -like some of these tables got real wide - -00:50:35.200 --> 00:50:36.800 -when we're stuffing svg - -00:50:36.800 --> 00:50:40.559 -tags into them and what we - -00:50:40.559 --> 00:50:44.160 -oh maybe it's not in these - -00:50:44.160 --> 00:50:50.079 -I thought it was - -00:50:50.079 --> 00:50:52.960 -special probably yeah no there it is - -00:50:52.960 --> 00:50:54.240 -yeah - -00:50:54.240 --> 00:50:56.000 -it was in level change it does the table +00:39:24.160 --> 00:39:30.510 +stamp it into a map graphically, and then save the map file -00:50:56.000 --> 00:50:58.720 -can you repeat okay great +00:39:30.510 --> 00:39:36.470 +out and load it back in later, so that we're able to just -00:50:58.720 --> 00:51:00.640 -up and down so fast I didn't realize so +00:39:36.470 --> 00:39:40.160 +pound out these maps real fast. -00:51:00.640 --> 00:51:01.920 -this first table +00:39:40.160 --> 00:39:44.480 +Using a graphical editor rather than having to hand code -00:51:01.920 --> 00:51:05.680 -we've got path and what is that stairs +00:39:44.480 --> 00:39:48.160 +every symbol and every square of the tables. -00:51:05.680 --> 00:51:08.800 -so the stairs level is one that draws in +00:39:48.160 --> 00:39:51.160 +So the process of doing that. -00:51:08.800 --> 00:51:10.079 -like a pink color +00:39:51.160 --> 00:39:56.190 +I hate them on things are a mess we've got covers off those -00:51:10.079 --> 00:51:11.920 -to highlight the places where you can +00:39:56.190 --> 00:40:03.160 +wires hanging out different stuff works on different days. -00:51:11.920 --> 00:51:13.440 -change level +00:40:03.160 --> 00:40:06.860 +Well, I will say in our defense this is exactly why we -00:51:13.440 --> 00:51:15.200 -and then if we scroll down to the second +00:40:06.860 --> 00:40:10.880 +staged a complicated thing, and probably we should have -00:51:15.200 --> 00:51:17.200 -half of this section +00:40:10.880 --> 00:40:14.510 +just gone with that instead of trying to give you the -00:51:17.200 --> 00:51:19.359 -the second table is going to have all of +00:40:14.510 --> 00:40:18.460 +experience of, of what it's like to use Emacs to do this -00:51:19.359 --> 00:51:20.960 -these same tiles in it but +00:40:18.460 --> 00:40:21.160 +which is sort of the last -00:51:20.960 --> 00:51:22.800 -instead of path and stairs we're going +00:40:21.160 --> 00:40:26.450 +thought there and my apologies for that if that's made it -00:51:22.800 --> 00:51:24.720 -to have other +00:40:26.450 --> 00:40:31.650 +harder to follow the thread. Let's check back now for -00:51:24.720 --> 00:51:27.920 -columns can we +00:40:31.650 --> 00:40:37.160 +questions and see if anybody wants to redirect at all. -00:51:27.920 --> 00:51:31.680 -see the next table +00:40:37.160 --> 00:40:41.438 +Oh yep, this. So what you're looking at all uses -00:51:31.680 --> 00:51:33.839 -there we go so the same tiles only here +00:40:41.439 --> 00:40:46.860 +progrmamatic SVG generation for question number four there, -00:51:33.839 --> 00:51:35.359 -we've got overlay +00:40:46.860 --> 00:40:52.160 +have you played with generating SVGs programmatically in Emacs. -00:51:35.359 --> 00:51:38.720 -documentation and behavior and I guess +00:40:52.160 --> 00:40:58.160 +That is what the maps are doing in terms of -00:51:38.720 --> 00:51:40.319 -we haven't talked about this at all the +00:40:58.160 --> 00:41:01.860 +being more explicit about that we started hand coding -00:51:40.319 --> 00:51:41.839 -behavior column +00:41:01.860 --> 00:41:05.650 +things and once we got the, the idea of what the code was -00:51:41.839 --> 00:51:44.880 -was our concept of a way that we could +00:41:05.650 --> 00:41:10.160 +going to look like we switched to doing it programmatically. -00:51:44.880 --> 00:51:47.520 -attach +00:41:10.160 --> 00:41:13.330 +So, we were going to open up maybe now we've got time we -00:51:47.520 --> 00:51:49.680 -functions basically to these different +00:41:13.330 --> 00:41:16.910 +can get into the tileset real quick. Sure, we definitely -00:51:49.680 --> 00:51:51.359 -areas of the map +00:41:16.910 --> 00:41:19.820 +didn't do any of the pathing slides and so now we've -00:51:51.359 --> 00:51:54.720 -because sometimes when you enter an area +00:41:19.820 --> 00:41:23.160 +skipped over some stuff we were going to present. -00:51:54.720 --> 00:51:57.760 -we want it to do something like +00:41:23.160 --> 00:41:27.030 +Yeah, that's right we skipped a whole bunch of slides and I -00:51:57.760 --> 00:51:59.920 -when you enter a stairs down maybe we +00:41:27.030 --> 00:41:31.160 +can certainly go back to them they're open here obviously. -00:51:59.920 --> 00:52:02.319 -want it to change to the next level +00:41:31.160 --> 00:41:34.110 +I'm right I was just showing off the sketching tool, -00:52:02.319 --> 00:52:04.559 -and draw the stairs up behind you and +00:41:34.110 --> 00:41:37.530 +briefly in that context but I think you're right, let's, we -00:52:04.559 --> 00:52:06.160 -draw you where you are +00:41:37.530 --> 00:41:40.800 +can jump over to the actually I should finish with this now -00:52:06.160 --> 00:52:09.200 -on the next level so +00:41:40.800 --> 00:41:42.160 +having teased it. -00:52:09.200 --> 00:52:11.040 -these are like hooks where we could +00:41:42.160 --> 00:41:46.970 +So let's do the same thing here Ctrl H M, and you'll see in -00:52:11.040 --> 00:52:12.240 -attach functions +00:41:46.970 --> 00:41:52.160 +this case there are very few key bindings that are set up. -00:52:12.240 --> 00:52:16.400 -or you know macros or whatever to +00:41:52.160 --> 00:41:57.320 +This shift delete has a terror or shift with a control -00:52:16.400 --> 00:52:18.480 -make the map have these behaviors as we +00:41:57.320 --> 00:42:01.920 +delete, it would seem to be. So that has a couple obvious -00:52:18.480 --> 00:52:23.440 -get further towards automation +00:42:01.920 --> 00:42:06.590 +bugs with it right didn't pick it didn't pick up those -00:52:23.440 --> 00:52:26.559 -cool um so that's that +00:42:06.590 --> 00:42:12.160 +control points until I reuse them not clearing that stack. -00:52:26.559 --> 00:52:30.839 -should be pretty close to our time +00:42:12.160 --> 00:42:16.720 +I think we can also should probably think about whether the -00:52:30.839 --> 00:52:33.920 -um questions or just say goodbye +00:42:16.720 --> 00:42:21.060 +origin should return and hey marking that origin would be -00:52:33.920 --> 00:52:36.880 -um yeah so there's the I'm sorry we +00:42:21.060 --> 00:42:25.370 +nice. So there's a tremendous amount to do here this is -00:52:36.880 --> 00:52:38.559 -couldn't show it earlier there is the +00:42:25.370 --> 00:42:30.090 +just showing that it is possible to use, essentially like a -00:52:38.559 --> 00:52:40.000 -battle board +00:42:30.090 --> 00:42:31.160 +touch input to, -00:52:40.000 --> 00:52:44.240 -um and so this is used just to keep +00:42:31.160 --> 00:42:40.730 +yeah, and then also we can switch over to our place tool, -00:52:44.240 --> 00:52:48.079 -track of hit points so with this example +00:42:40.730 --> 00:42:46.830 +and hopefully we can get a nice big menu of all the tiles that -00:52:48.079 --> 00:52:49.319 -battle board +00:42:46.830 --> 00:42:50.160 +Erik prepared for the game maps. -00:52:49.319 --> 00:52:51.680 -dmbattleboard.el there's there's a +00:42:50.160 --> 00:42:55.160 +That was probably a terrible choice but there you have just -00:52:51.680 --> 00:52:53.760 -complete example of not only +00:42:55.160 --> 00:42:57.160 +a bit of corridor right. -00:52:53.760 --> 00:52:57.200 -in a single file repub filling out the +00:42:57.160 --> 00:43:01.160 +That looks. -00:52:57.200 --> 00:53:00.480 -the cells and the tiles but then coming +00:43:01.160 --> 00:43:03.160 +And even the click. -00:53:00.480 --> 00:53:00.960 -in +00:43:03.160 --> 00:43:06.870 +Yep, and this click action here is the last thing I -00:53:00.960 --> 00:53:04.640 -and keeping the org mode file in sync +00:43:06.870 --> 00:43:10.510 +was working on before I dropped everything to build the -00:53:04.640 --> 00:53:05.280 -with +00:43:10.510 --> 00:43:14.160 +decks that we will soon share for this conference. -00:53:05.280 --> 00:53:09.040 -with clicks so and I can press the star +00:43:14.160 --> 00:43:20.160 +So okay, back to the tile sets. -00:53:09.040 --> 00:53:12.319 -key and set my damage to -1 and +00:43:20.160 --> 00:43:24.130 +So the way we approached drawing it programmatically is we -00:53:12.319 --> 00:53:15.359 -take the damage back off I just haven't +00:43:24.130 --> 00:43:28.160 +broke our code up into little snippets we called tiles. -00:53:15.359 --> 00:53:16.400 -spent a lot of time +00:43:28.160 --> 00:43:31.240 +And so this is where I was going to open up the tiles out -00:53:16.400 --> 00:53:18.079 -building up fancy bindings for this +00:43:31.240 --> 00:43:34.610 +here, basically each tile has a name, and then with that -00:53:18.079 --> 00:53:20.800 -you'll also find that the crew +00:43:34.610 --> 00:43:38.160 +name we place data into different layers of the image. -00:53:20.800 --> 00:53:23.119 -probably find how I figure out what was +00:43:38.160 --> 00:43:43.290 +Some of the layers are just SVG paths, and the data is just -00:53:23.119 --> 00:53:23.839 -clicked on +00:43:43.290 --> 00:43:48.430 +SVG commands, like we saw in that handwritten code, and -00:53:23.839 --> 00:53:26.880 -in the code hard but if I just assign +00:43:48.430 --> 00:43:53.560 +some of it is compositions of other tiles, so a tile can be -00:53:26.880 --> 00:53:28.000 -something recognizable +00:43:53.560 --> 00:43:56.160 +made up of other tiles. -00:53:28.000 --> 00:53:33.520 -for damage and then come into +00:43:56.160 --> 00:44:00.270 +Furthermore, some of these tiles have conditional code in -00:53:33.520 --> 00:53:35.440 -it will now have opened the org mode +00:44:00.270 --> 00:44:04.460 +it, where like some of this stuff is talking about elf and -00:53:35.440 --> 00:53:37.040 -file behind the scenes because it's +00:44:04.460 --> 00:44:05.160 +bang elf. -00:53:37.040 --> 00:53:41.280 -changing it +00:44:05.160 --> 00:44:09.540 +So the map is going to be drawn differently depending on -00:53:41.280 --> 00:53:44.640 -and we can then look at that file a +00:44:09.540 --> 00:44:13.160 +whether or not there's elves in the party. -00:53:44.640 --> 00:53:47.599 -little bit and hopefully +00:44:13.160 --> 00:44:17.160 +So, and that's the demo they broke. -00:53:47.599 --> 00:53:51.040 -that is un +00:44:17.160 --> 00:44:20.160 +So the engine has to make all those decisions. -00:53:51.040 --> 00:53:53.440 -uh large enough you can kind of see +00:44:20.160 --> 00:44:22.887 +And that's what we're calling predicated drawing. Oh, there's -00:53:53.440 --> 00:53:55.520 -there's our 17 damage landed +00:44:22.888 --> 00:44:26.810 +a special room here. Do you have any elves? You do. So I -00:53:55.520 --> 00:53:59.119 -in armor the logic that sits behind that +00:44:26.810 --> 00:44:33.160 +draw it the "there is elves" way. -00:53:59.119 --> 00:54:01.200 -to figure out the part of the screen +00:44:33.160 --> 00:44:37.440 +Yeah, so we built up the set of tiles, and then we -00:54:01.200 --> 00:54:08.880 -is not necessarily our finest work +00:44:37.440 --> 00:44:42.450 +basically made map files, which take our map and break it -00:54:08.880 --> 00:54:11.839 -uh uh but it but it does work and it's +00:44:42.450 --> 00:44:46.840 +up into XY grids, and then we drop these tiles into -00:54:11.839 --> 00:54:12.319 -one for +00:44:46.840 --> 00:44:49.160 +positions on the map. -00:54:12.319 --> 00:54:14.000 -the stuff was used on the map a little +00:44:49.160 --> 00:44:52.060 +So we can use the same tile square after square after -00:54:14.000 --> 00:54:15.920 -bit too we didn't really need to show +00:44:52.060 --> 00:44:55.470 +square. When there's a corridor north-south, it's the same -00:54:15.920 --> 00:54:17.520 -that in the demo but as you're scrolling +00:44:55.470 --> 00:44:59.980 +tile over and over again. And that makes it easy to reuse -00:54:17.520 --> 00:54:19.680 -around there's like a highlighter +00:44:59.980 --> 00:45:01.160 +the code. -00:54:19.680 --> 00:54:22.960 -um that that you know we were drawing on +00:45:01.160 --> 00:45:12.370 +And also, when we go to present the -- what am I trying to -00:54:22.960 --> 00:54:24.720 -shaft to show you which square you've +00:45:12.370 --> 00:45:16.180 +say -- the drawing in fog of war mode, as we move down the -00:54:24.720 --> 00:54:26.160 -got selected +00:45:16.180 --> 00:45:20.280 +corridor, we can just add the necessary code one bit at a -00:54:26.160 --> 00:54:28.800 -um because we were having trouble with +00:45:20.280 --> 00:45:24.160 +time to the visible image, so that what we're displaying -00:54:28.800 --> 00:54:29.839 -that code +00:45:24.160 --> 00:45:28.160 +doesn't contain any data except what the party has already -00:54:29.839 --> 00:54:31.280 -initially and we were sometimes +00:45:28.160 --> 00:45:30.160 +discovered. -00:54:31.280 --> 00:54:36.839 -revealing the wrong +00:45:30.160 --> 00:45:34.720 +And thus we have kind of spoiler-rich documents sitting on -00:54:36.839 --> 00:54:38.720 -okay +00:45:34.720 --> 00:45:39.120 +the GM server, and then less -- and spoiler-free data that -00:54:38.720 --> 00:54:40.480 -and I don't know how we're set for time +00:45:39.120 --> 00:45:43.160 +flows down to the org mode files on the player system. -00:54:40.480 --> 00:54:42.160 -but I just saw a message +00:45:43.160 --> 00:45:47.660 +And the only real challenge is making sure that nothing -00:54:42.160 --> 00:54:44.400 -um from trixie that she could jump on if +00:45:47.660 --> 00:45:52.230 +that the game does can mess with the users -- the players' -00:54:44.400 --> 00:54:46.480 -we want her oh that would be amazing +00:45:52.230 --> 00:45:56.610 +data file, in case they might have their own notes and -00:54:46.480 --> 00:54:47.920 -yeah go ahead and invite her in I'll +00:45:56.610 --> 00:46:03.800 +things in it. That would be the one, you know, number one -00:54:47.920 --> 00:54:51.680 -just cut to the scene as soon as she's +00:46:03.800 --> 00:46:06.160 +thing to avoid. -00:54:51.680 --> 00:54:56.160 -I in uh yeah so we're reaching the ask +00:46:06.160 --> 00:46:09.200 +Another thing we can talk about here is that there are -00:54:56.160 --> 00:54:56.799 -me any +00:46:09.200 --> 00:46:12.350 +layers. You can see this table at the bottom has tile and -00:54:56.799 --> 00:54:58.960 -anything uh portion of the program here +00:46:12.350 --> 00:46:16.860 +overlay. The overlay column is just going to contain some -00:54:58.960 --> 00:55:01.200 -with what uh with what time we have left +00:46:16.860 --> 00:46:19.160 +actual SVG XML style tags. -00:55:01.200 --> 00:55:02.559 -for your questions +00:46:19.160 --> 00:46:23.100 +So that's where we can add whatever text elements or other -00:55:02.559 --> 00:55:05.200 -um please correct me if we're still like +00:46:23.100 --> 00:46:27.120 +SVG, like raw SVG tags we want. Whereas a lot of the other -00:55:05.200 --> 00:55:06.160 -10 minutes +00:46:27.120 --> 00:46:30.980 +layers are going to be like path layers, we've got water -00:55:06.160 --> 00:55:08.799 -you know if we're if we're more than +00:46:30.980 --> 00:46:33.160 +layers and beach layers. -00:55:08.799 --> 00:55:10.000 -like +00:46:33.160 --> 00:46:36.370 +And our plan was to have a style sheet that defines how -00:55:10.000 --> 00:55:12.640 -15 to 20 minutes from our time but I I +00:46:36.370 --> 00:46:39.790 +each of those layers are represented. So like when the -00:55:12.640 --> 00:55:13.760 -suspect we've less weight +00:46:39.790 --> 00:46:43.140 +water gets drawn blue and it's got arrows on it giving it -00:55:13.760 --> 00:55:16.640 -left way less than that and out of +00:46:43.140 --> 00:46:47.140 +direction, all of that can be customized with a style sheet -00:55:16.640 --> 00:55:17.440 -respect for +00:46:47.140 --> 00:46:50.160 +to change the water to be whatever you want. -00:55:17.440 --> 00:55:24.319 -all the other presenters um +00:46:50.160 --> 00:46:53.430 +And like we have beaches as yellow, but maybe you like -00:55:24.319 --> 00:55:28.720 -oh I don't want to close that actually +00:46:53.430 --> 00:46:56.160 +beaches as red or, you know, whatever. -00:55:28.720 --> 00:55:30.640 -I think I may have found an old version +00:46:56.160 --> 00:47:03.570 +So we also built some test programs and various -- I'm not -00:55:30.640 --> 00:55:32.839 -of my slides that could have some good +00:47:03.570 --> 00:47:05.900 +sure what kind of shape we're going to find these in, but -00:55:32.839 --> 00:55:35.200 -stuff +00:47:05.900 --> 00:47:07.160 +we can try running them. -00:55:35.200 --> 00:55:36.799 -it's been an event for a couple of weeks +00:47:07.160 --> 00:47:13.950 +Here, for example, is just a very basic -- using the same -00:55:36.799 --> 00:55:38.799 -here I had a break in and uh +00:47:13.950 --> 00:47:21.160 +file to define the tiles and then the layout, so to speak. -00:55:38.799 --> 00:55:41.359 -my somebody got into our bank accounts +00:47:21.160 --> 00:47:25.160 +Oh, look at that. -00:55:41.359 --> 00:55:43.599 -and +00:47:25.160 --> 00:47:29.160 +There's the layout. Okay, so that actually looks fine. Tile. -00:55:43.599 --> 00:55:46.880 -nasty business just a lot going on over +00:47:29.160 --> 00:47:33.430 +And it's path. So this is defining a tile named "seas" and -00:55:46.880 --> 00:55:50.720 -over this whole year I think +00:47:33.430 --> 00:47:37.160 +it's going to have a list of tiles defined above. -00:55:50.720 --> 00:55:53.040 -do we have more questions to shag or +00:47:37.160 --> 00:47:41.120 +And you'll notice also that we can just sort of freely -00:55:53.040 --> 00:55:53.839 -where +00:47:41.120 --> 00:47:44.750 +define and redefine and it sort of figures out, oh, this -00:55:53.839 --> 00:55:56.960 -sure so I think +00:47:44.750 --> 00:47:47.160 +must still be part of the B row. -00:55:56.960 --> 00:55:58.799 -there was at least one we deferred a +00:47:47.160 --> 00:48:00.160 +We could also have done this. -00:55:58.799 --> 00:56:01.040 -little bit uh what the game +00:48:00.160 --> 00:48:08.160 +Okay, so this would work as would this. -00:56:01.040 --> 00:56:05.040 -is +00:48:08.160 --> 00:48:11.930 +>> Early on in development when we were talking about -00:56:05.040 --> 00:56:06.799 -uh always eight characters that can be +00:48:11.930 --> 00:48:16.520 +getting data in and out of these org tables, it was kind of -00:56:06.799 --> 00:56:08.400 -divided right that's so always eight +00:48:16.520 --> 00:48:22.160 +a priority to us to leave the way the data is organized -00:56:08.400 --> 00:56:10.000 -characters that can be divided between +00:48:22.160 --> 00:48:25.160 +open to the users and to the dungeon masters. -00:56:10.000 --> 00:56:12.160 -the party is the classic formula +00:48:25.160 --> 00:48:30.860 +So while we set our tile set apart from our map sets, this -00:56:12.160 --> 00:56:14.319 -it actually works pretty well for a +00:48:30.860 --> 00:48:36.430 +clearly shows that you can cram a tile set and a map into a -00:56:14.319 --> 00:56:16.240 -conversational group remember that +00:48:36.430 --> 00:48:38.160 +single file. -00:56:16.240 --> 00:56:17.760 -role-playing games are about talking to +00:48:38.160 --> 00:48:41.170 +So in situations like the surface where we're using -00:56:17.760 --> 00:56:18.480 -each other +00:48:41.170 --> 00:48:44.610 +different tiles from other maps, maybe it makes sense to -00:56:18.480 --> 00:56:20.000 -and being good at them is about taking +00:48:44.610 --> 00:48:47.890 +move, you know, those tiles just into the file with your -00:56:20.000 --> 00:56:22.079 -excellent notes so +00:48:47.890 --> 00:48:49.160 +map. -00:56:22.079 --> 00:56:23.200 -when you're sitting around with a group +00:48:49.160 --> 00:48:51.880 +But we also wanted to make sure, like, it's hard for us to -00:56:23.200 --> 00:56:24.559 -of people and you're going to have to +00:48:51.880 --> 00:48:54.640 +predict how other people are going to want to use this when -00:56:24.559 --> 00:56:25.920 -wait for them while they dig through +00:48:54.640 --> 00:48:56.160 +they design their games. -00:56:25.920 --> 00:56:26.880 -their notes +00:48:56.160 --> 00:49:00.780 +So we wanted to leave it as versatile as possible about how -00:56:26.880 --> 00:56:28.720 -and listen to all of the things they +00:49:00.780 --> 00:49:02.160 +you can use it. -00:56:28.720 --> 00:56:30.319 -find interesting to say +00:49:02.160 --> 00:49:04.810 +>> Where it matters, right? Not support every feature in -00:56:30.319 --> 00:56:32.240 -and try to reach an imaginative place +00:49:04.810 --> 00:49:05.160 +the world. -00:56:32.240 --> 00:56:34.160 -that you can stay together +00:49:05.160 --> 00:49:08.560 +I can't count the number of times I said, Erik, Erik, Erik, -00:56:34.160 --> 00:56:36.160 -while you're doing all that and working +00:49:08.560 --> 00:49:12.000 +hey, if we do it like this, people will be -- and he just, -00:56:36.160 --> 00:56:38.319 -in dice and remembering the rules +00:49:12.000 --> 00:49:14.160 +like, does it have to do that? -00:56:38.319 --> 00:56:40.880 -it's actually a complicated activity I +00:49:14.160 --> 00:49:19.090 +Like, do we need it right away? Do you have to really -00:56:40.880 --> 00:56:43.200 -liken it more to a bridge game +00:49:19.090 --> 00:49:21.160 +rewrite everything so it can all do that? -00:56:43.200 --> 00:56:46.240 -than to like uh +00:49:21.160 --> 00:49:26.160 +And a lot of those conversations, too. -00:56:46.240 --> 00:56:48.960 -you know parcheesi or perhaps even like +00:49:26.160 --> 00:49:30.160 +But the key flexibilities are really there. -00:56:48.960 --> 00:56:51.359 -risk or access and allies or other games +00:49:30.160 --> 00:49:32.160 +People might want to use a lot of different files. -00:56:51.359 --> 00:56:52.160 -that +00:49:32.160 --> 00:49:34.160 +They might want to lay the tables out however they want. -00:56:52.160 --> 00:56:54.319 -have have definitely the strategy to +00:49:34.160 --> 00:49:37.590 +They have to be able to say, hey, this is a table that has -00:56:54.319 --> 00:56:56.160 -them but +00:49:37.590 --> 00:49:40.950 +data that's controlled by the game, and everything else in -00:56:56.160 --> 00:57:00.160 -I don't eric your thoughts +00:49:40.950 --> 00:49:43.160 +the file is not the game's problem. -00:57:00.160 --> 00:57:03.920 -yeah I mean I think that's fair um +00:49:43.160 --> 00:49:45.980 +>> And our table, some of our tables started getting really -00:57:03.920 --> 00:57:06.640 -you know yes definitely the the +00:49:45.980 --> 00:49:48.160 +wide, so we started striping the tables. -00:57:06.640 --> 00:57:08.160 -tradition is to always have eight +00:49:48.160 --> 00:49:52.140 +We'll repeat the same table over and over and over again to -00:57:08.160 --> 00:57:09.440 -characters in the party +00:49:52.140 --> 00:49:56.180 +get all of the columns in there without making it, you know, -00:57:09.440 --> 00:57:12.079 -and you know one of the great things +00:49:56.180 --> 00:49:58.160 +a million miles wide. -00:57:12.079 --> 00:57:13.760 -about dungeon is that everybody who +00:49:58.160 --> 00:49:59.160 +>> Yeah. -00:57:13.760 --> 00:57:15.200 -writes their own dungeon +00:49:59.160 --> 00:50:02.450 +Do you want to -- should I go ahead and pull open, like, a -00:57:15.200 --> 00:57:18.000 -gets to write their own rules and is +00:50:02.450 --> 00:50:04.160 +level here, do you think? -00:57:18.000 --> 00:57:19.440 -free to change whatever +00:50:04.160 --> 00:50:05.160 +>> Sure. -00:57:19.440 --> 00:57:21.760 -you want and that being said I've +00:50:05.160 --> 00:50:06.160 +>> Just to have shown it. -00:57:21.760 --> 00:57:22.720 -certainly seen +00:50:06.160 --> 00:50:08.750 +>> The file set's a great example of striped tables if you -00:57:22.720 --> 00:57:25.839 -people try to take on challenging that +00:50:08.750 --> 00:50:11.160 +look down, like, in the level change feature. -00:57:25.839 --> 00:57:28.079 -always eight characters in a party +00:50:11.160 --> 00:50:18.160 +>> Oh, sure. -00:57:28.079 --> 00:57:30.640 -thing um I've seen people take +00:50:18.160 --> 00:50:21.160 +>> Sorry, I'm not quite sitting well to my keyboard here. -00:57:30.640 --> 00:57:32.640 -approaches like every player gets two +00:50:21.160 --> 00:50:30.160 +I can just readjust things real quick. -00:57:32.640 --> 00:57:34.640 -characters and then you can have a party +00:50:30.160 --> 00:50:33.920 +So what, you know, you can see here, like, some of these -00:57:34.640 --> 00:57:36.319 -ranging from two to ten +00:50:33.920 --> 00:50:38.160 +tables got real wide when we're stuffing SVG tags into them. -00:57:36.319 --> 00:57:38.079 -or there's always going to be ten or +00:50:38.160 --> 00:50:44.160 +And what we -- oh, maybe it's not in these. -00:57:38.079 --> 00:57:40.000 -there's you know this or that or people +00:50:44.160 --> 00:50:50.160 +I thought it was. -00:57:40.000 --> 00:57:43.200 -have um tried stuff and none of it has +00:50:50.160 --> 00:50:51.160 +It's special, probably. -00:57:43.200 --> 00:57:45.280 -really worked out very satisfactorily we +00:50:51.160 --> 00:50:52.160 +>> Yeah. -00:57:45.280 --> 00:57:45.839 -always +00:50:52.160 --> 00:50:54.160 +No, there it is, yeah. -00:57:45.839 --> 00:57:48.319 -seem to keep coming back to our um party +00:50:54.160 --> 00:50:55.160 +It was in level change. -00:57:48.319 --> 00:57:49.680 -of eight +00:50:55.160 --> 00:50:57.160 +It does the table key repeat. -00:57:49.680 --> 00:57:54.160 -yeah it's I I I I it's one of the things +00:50:57.160 --> 00:50:58.160 +>> Okay, great. -00:57:54.160 --> 00:57:55.839 -dungeon that you can't change when you +00:50:58.160 --> 00:50:59.720 +>> You were just scrolling up and down so fast I didn't -00:57:55.839 --> 00:57:57.359 -write your own dungeon +00:50:59.720 --> 00:51:00.160 +realize. -00:57:57.359 --> 00:57:58.720 -and that's the reason it's so +00:51:00.160 --> 00:51:04.270 +So this first table, we've got path and what is that, -00:57:58.720 --> 00:58:00.960 -complicated as a as a software +00:51:04.270 --> 00:51:05.160 +stairs? -00:58:00.960 --> 00:58:03.119 -project why it's taken us decades +00:51:05.160 --> 00:51:09.010 +So the stairs level is one that draws in, like, a pink -00:58:03.119 --> 00:58:04.559 -because +00:51:09.010 --> 00:51:13.160 +color to highlight places where you can change level. -00:58:04.559 --> 00:58:08.000 -trying to model the data for example or +00:51:13.160 --> 00:51:16.120 +And then if we scroll down to the second half of this -00:58:08.000 --> 00:58:11.280 -really any attempt to +00:51:16.120 --> 00:51:19.380 +section, the second table is going to have all of these -00:58:11.280 --> 00:58:14.160 -quantify it in specific terms always +00:51:19.380 --> 00:51:24.000 +same tiles in it, but instead of path and stairs, we're -00:58:14.160 --> 00:58:15.680 -falls to examples +00:51:24.000 --> 00:51:27.160 +going to have other columns. -00:58:15.680 --> 00:58:18.880 -well you know dungeons usually have +00:51:27.160 --> 00:51:31.160 +Can we see the next table? -00:58:18.880 --> 00:58:22.079 -elves dwarves and humans they have uh +00:51:31.160 --> 00:51:32.160 +There we go. -00:58:22.079 --> 00:58:25.280 -priests wizards and warriors uh they +00:51:32.160 --> 00:51:35.610 +So the same tiles, only here we've got overlay, -00:58:25.280 --> 00:58:27.599 -have eight characters in the party +00:51:35.610 --> 00:51:38.160 +documentation, and behavior. -00:58:27.599 --> 00:58:30.000 -the bell rocks are particularly nasty +00:51:38.160 --> 00:51:40.160 +And I guess we haven't talked about this at all. -00:58:30.000 --> 00:58:31.680 -and live in a room of some +00:51:40.160 --> 00:51:44.920 +The behavior column was our concept of a way that we could -00:58:31.680 --> 00:58:35.119 -specific shape um spoilers +00:51:44.920 --> 00:51:50.100 +attach functions, basically, to these different areas of -00:58:35.119 --> 00:58:38.319 -uh right and we don't tell you the rules +00:51:50.100 --> 00:51:51.160 +the map. -00:58:38.319 --> 00:58:39.520 -and that's what you know +00:51:51.160 --> 00:51:55.920 +Because sometimes when you enter an area, we want it to do -00:58:39.520 --> 00:58:40.960 -and you sit down at the table and you +00:51:55.920 --> 00:51:57.160 +something. -00:58:40.960 --> 00:58:42.640 -say what's your character name and +00:51:57.160 --> 00:52:00.880 +Like when you enter a stairs down, maybe we want it to -00:58:42.640 --> 00:58:44.480 -what's your special power +00:52:00.880 --> 00:52:04.850 +change to the next level and draw the stairs up behind you -00:58:44.480 --> 00:58:48.400 -and and then I say uh I +00:52:04.850 --> 00:52:08.160 +and draw you where you are on the next level. -00:58:48.400 --> 00:58:51.599 -I I'm zelda and uh +00:52:08.160 --> 00:52:13.470 +So these are like hooks where we could attach functions or, -00:58:51.599 --> 00:58:53.839 -I I have this bridge that I can put down +00:52:13.470 --> 00:52:18.390 +you know, macros or whatever to make the map have these -00:58:53.839 --> 00:58:56.000 -that always gets me across the river +00:52:18.390 --> 00:52:23.160 +behaviors as we get further towards automation. -00:58:56.000 --> 00:58:59.040 -um so let's touch on special power real +00:52:23.160 --> 00:52:25.160 +Cool. -00:58:59.040 --> 00:58:59.359 -quick +00:52:25.160 --> 00:52:31.160 +So that's that should be pretty close to our time. -00:58:59.359 --> 00:59:01.119 -since that's one of the things that is +00:52:31.160 --> 00:52:34.160 +Questions or just say goodbye. -00:59:01.119 --> 00:59:03.280 -kind of unique to dungeon +00:52:34.160 --> 00:52:38.160 +Yeah, so there's the I'm sorry we couldn't show it earlier. -00:59:03.280 --> 00:59:06.160 -and one of the things that is the +00:52:38.160 --> 00:52:41.160 +There is the battle board. -00:59:06.160 --> 00:59:06.720 -biggest +00:52:41.160 --> 00:52:46.160 +And so this is used just to keep track of hit points. -00:59:06.720 --> 00:59:08.960 -challenge to us in trying to code a +00:52:46.160 --> 00:52:50.540 +So with this example, battle board, dm battle board.el, -00:59:08.960 --> 00:59:10.240 -system like this for +00:52:50.540 --> 00:52:54.590 +there's there's a complete example of not only in a single -00:59:10.240 --> 00:59:13.200 -automated play and that's that every +00:52:54.590 --> 00:52:58.430 +file reaper, we filling out the tell the cells and the -00:59:13.200 --> 00:59:14.319 -character gets a +00:52:58.430 --> 00:53:03.720 +tiles, but then coming in and keeping the org mode file in -00:59:14.319 --> 00:59:17.119 -unique special power and traditionally +00:53:03.720 --> 00:53:06.160 +sync with with clicks. -00:59:17.119 --> 00:59:18.000 -you negotiate +00:53:06.160 --> 00:53:11.040 +So, and I can press the star key and set my damage to minus -00:59:18.000 --> 00:59:19.520 -your special power with the dungeon +00:53:11.040 --> 00:53:14.160 +one and take the damage back off. -00:59:19.520 --> 00:59:21.839 -master when you create your character +00:53:14.160 --> 00:53:17.770 +I just haven't spent a lot of time building up fancy bind -00:59:21.839 --> 00:59:24.079 -and occasionally throughout the course +00:53:17.770 --> 00:53:21.620 +ings for this, you'll also find that the crew probably find -00:59:24.079 --> 00:59:25.839 -of the character's life their special +00:53:21.620 --> 00:53:25.270 +how I figure out what was clicked on in the code hard, but -00:59:25.839 --> 00:59:27.359 -power might change +00:53:25.270 --> 00:53:30.010 +if I just assign something recognizable for damage, and -00:59:27.359 --> 00:59:29.920 -due to game circumstances usually it +00:53:30.010 --> 00:53:33.160 +then come into. -00:59:29.920 --> 00:59:33.280 -improves but sometimes not +00:53:33.160 --> 00:53:39.030 +It will now have opened the org mode file behind the scenes -00:59:33.280 --> 00:59:34.960 -uh and that's those are the most fun +00:53:39.030 --> 00:53:41.160 +because it's changing it. -00:59:34.960 --> 00:59:36.960 -conversations right sometimes we have +00:53:41.160 --> 00:53:48.340 +And we can then look at that file a little bit and -00:59:36.960 --> 00:59:39.440 -fun gaming sessions where we barely get +00:53:48.340 --> 00:53:54.130 +hopefully that is on large enough you can kind of see there -00:59:39.440 --> 00:59:41.760 -all the characters created and started +00:53:54.130 --> 00:53:57.160 +'s our 17 damage landed in armor. -00:59:41.760 --> 00:59:43.680 -because we get off into arguing about +00:53:57.160 --> 00:54:04.200 +The logic that sits behind that to figure out the part of -00:59:43.680 --> 00:59:45.440 -the special powers no zelda special +00:54:04.200 --> 00:54:10.160 +the screen is not necessarily our finest work. -00:59:45.440 --> 00:59:48.319 -powers obviously the candle come on +00:54:10.160 --> 00:54:12.960 +But it does work and that's one kind of stuff was used on -00:59:48.319 --> 00:59:53.359 -also that was link not zelda +00:54:12.960 --> 00:54:16.030 +the map a little bit too. We didn't really get to show that -00:59:53.359 --> 00:59:56.240 -I still have my t-shirt hey there she is +00:54:16.030 --> 00:54:18.970 +in the demo but as you're scrolling around there's like a -00:59:56.240 --> 01:00:01.440 -let's cut scene +00:54:18.970 --> 00:54:22.160 +highlighter that that, you know, we were drawing on. -01:00:01.440 --> 01:00:05.839 -you get video fun filters today because +00:54:22.160 --> 00:54:26.160 +Oh sure, show you which square you've got selected. -01:00:05.839 --> 01:00:07.359 -that's what we got going on over here +00:54:26.160 --> 00:54:30.300 +We were having trouble with that code. Initially, and we -01:00:07.359 --> 01:00:08.799 -today all right I'm gonna recut +00:54:30.300 --> 00:54:33.160 +were sometimes revealing the wrong. -01:00:08.799 --> 01:00:18.079 -everybody hang on tight +00:54:33.160 --> 00:54:38.160 +Okay. -01:00:18.079 --> 01:00:20.799 -all right there's eric this is gonna be +00:54:38.160 --> 00:54:41.320 +And I don't know how we're set for time but I just saw a -01:00:20.799 --> 01:00:23.200 -eric for a second hope +00:54:41.320 --> 00:54:45.240 +message from Trixie that she could jump on if we want her. -01:00:23.200 --> 01:00:25.200 -no worries and welcome to the welcome to +00:54:45.240 --> 00:54:48.290 +Oh, that would be amazing.

So, I think there was at least one we deferred a -01:01:07.680 --> 01:01:09.440 -vocabulary disconnect +00:56:02.240 --> 00:56:06.160 +little bit with the game is -01:01:09.440 --> 01:01:12.480 -like and this actually kind of comes up +00:56:06.160 --> 00:56:08.990 +always eight characters that can be divided right that's so -01:01:12.480 --> 01:01:13.359 -a lot +00:56:08.990 --> 00:56:11.660 +always eight characters that can be divided between the -01:01:13.359 --> 01:01:15.200 -in conversation with corona and eric and +00:56:11.660 --> 00:56:14.540 +party is the classic formula, it actually works pretty well -01:01:15.200 --> 01:01:18.000 -I but copy paste versus +00:56:14.540 --> 00:56:16.160 +for a conversational group. -01:01:18.000 --> 01:01:21.920 -what yank and w +00:56:16.160 --> 00:56:18.810 +I think the idea that role playing games are about talking -01:01:21.920 --> 01:01:27.920 -whatever w +00:56:18.810 --> 00:56:21.330 +to each other and being good at them is about taking -01:01:27.920 --> 01:01:30.000 -why would you even do that to us right +00:56:21.330 --> 00:56:23.770 +excellent notes.

And so, -01:08:26.640 --> 01:08:30.239 -and I think taking a dungeon and +01:07:48.670 --> 01:07:52.230 +like to know that there's something that exists, that is -01:08:30.239 --> 01:08:34.480 -like using it to +01:07:52.230 --> 01:07:54.160 +like purely hierarchical. -01:08:34.480 --> 01:08:35.839 -like combining it with org mode +01:07:54.160 --> 01:07:59.170 +It's incredible, like I can just run a report, basically -01:08:35.839 --> 01:08:37.759 -basically um +01:07:59.170 --> 01:08:03.550 +and get all of my like to do lists that I didn't have to -01:08:37.759 --> 01:08:41.040 -really yeah I'm excited about it I'm +01:08:03.550 --> 01:08:06.160 +put in one specific place. -01:08:41.040 --> 01:08:42.560 -excited to see like what it can do for +01:08:06.160 --> 01:08:13.190 +And, like, that's kind of been a complex issue for me of -01:08:42.560 --> 01:08:44.159 -player groups +01:08:13.190 --> 01:08:16.680 +like, okay, I have all these to do lists, like in Google -01:08:44.159 --> 01:08:47.759 -um yeah especially +01:08:16.680 --> 01:08:19.160 +Keep or whatever like what do I do with them now. -01:08:47.759 --> 01:08:50.319 -like I was excited about dungeon mode um +01:08:19.160 --> 01:08:24.160 +So being able to like pull them into one list. -01:08:50.319 --> 01:08:52.319 -before the pandemic and now like I'm +01:08:24.160 --> 01:08:27.160 +And then recycle through them is really incredible. -01:08:52.319 --> 01:08:53.920 -only more enthusiastic +01:08:27.160 --> 01:08:35.500 +And I think taking dungeon and like using it to like -01:08:53.920 --> 01:08:57.120 -so yeah uh definitely the pandemic has +01:08:35.500 --> 01:08:40.160 +combining it with org mode basically really. -01:08:57.120 --> 01:08:58.400 -been the greatest thing that happened to +01:08:40.160 --> 01:08:44.210 +I'm excited about it and I'm excited to see like what it -01:08:58.400 --> 01:08:59.120 -this game +01:08:44.210 --> 01:08:46.160 +can do for player groups. -01:08:59.120 --> 01:09:02.080 -terrible terrible as it is to say that +01:08:46.160 --> 01:08:49.190 +Especially now that quarantine like I was excited about -01:09:02.080 --> 01:09:02.640 -it +01:08:49.190 --> 01:08:50.160 +dungeon mode. -01:09:02.640 --> 01:09:05.120 -if we uh needed a hobby and it turns out +01:08:50.160 --> 01:08:54.040 +Before the pandemic and now like I'm only more enthusiastic. -01:09:05.120 --> 01:09:06.719 -role-playing games are +01:08:54.040 --> 01:08:57.940 +So, yeah, definitely the pandemic has been the greatest -01:09:06.719 --> 01:09:11.279 -a really good fit +01:08:57.940 --> 01:09:01.720 +thing that happened to this game, terrible terrible as it -01:09:11.279 --> 01:09:13.839 -so um so I think that's probably about +01:09:01.720 --> 01:09:05.090 +is to say that it, if we needed a hobby and it turns out -01:09:13.839 --> 01:09:14.799 -our time +01:09:05.090 --> 01:09:11.160 +role playing games are are really good. -01:09:14.799 --> 01:09:18.560 -um I'm guessing that's my call and +01:09:11.160 --> 01:09:16.610 +So, so I think that's probably about our time. I'm guessing -01:09:18.560 --> 01:09:21.759 -uh thank you very much thank you +01:09:16.610 --> 01:09:21.160 +that's my call.

-00:00:53.039 --> 00:00:54.559 -what's different and - -00:00:54.559 --> 00:00:57.360 -what is v term exactly so v term is a - -00:00:57.360 --> 00:00:58.879 -terminal emulator built - -00:00:58.879 --> 00:01:01.120 -on top of an external library the - -00:01:01.120 --> 00:01:02.719 -library is called libvi term - -00:01:02.719 --> 00:01:05.519 -and is the same library used by newton - -00:01:05.519 --> 00:01:07.200 -for their own terminal emulator - -00:01:07.200 --> 00:01:10.000 -it's a c library and this is what gives - -00:01:10.000 --> 00:01:10.799 -us - -00:01:10.799 --> 00:01:15.119 -a lot of good features first the speed - -00:01:15.119 --> 00:01:17.280 -time spent here 0.6 is essentially the - -00:01:17.280 --> 00:01:18.479 -time that it takes to - -00:01:18.479 --> 00:01:21.520 -one convert the emax representation of - -00:01:21.520 --> 00:01:22.240 -like text - -00:01:22.240 --> 00:01:23.840 -into the visa and representation of what -

-00:01:31.840 --> 00:01:33.680 -involved so these are the 0.6 seconds - -00:01:33.680 --> 00:01:34.240 -there - -00:01:34.240 --> 00:01:36.960 -as we say in the in ancestor that's much - -00:01:36.960 --> 00:01:37.920 -much - -00:01:37.920 --> 00:01:39.920 -more time it's much slower so the - -00:01:39.920 --> 00:01:41.680 -terminal will feel much snappier much - -00:01:41.680 --> 00:01:42.880 -faster - -00:01:42.880 --> 00:01:46.079 -but that's not the main benefit or the - -00:01:46.079 --> 00:01:47.840 -only benefit of using this external - -00:01:47.840 --> 00:01:48.799 -library - -00:01:48.799 --> 00:01:52.320 -feature the second big benefit - -00:01:52.320 --> 00:01:55.439 -is that v term has support for all the - -00:01:55.439 --> 00:01:56.560 -escape codes - -00:01:56.560 --> 00:01:59.200 -that exterm has support for so v term is - -00:01:59.200 --> 00:02:01.119 -essentially as running x term - -00:02:01.119 --> 00:02:03.600 -inside an imax buffer so let's see that - -00:02:03.600 --> 00:02:04.799 -this for example - -00:02:04.799 --> 00:02:07.119 -let's start by looking at the support - -00:02:07.119 --> 00:02:08.239 -for colors - -00:02:08.239 --> 00:02:09.920 -we have support for all the colors out - -00:02:09.920 --> 00:02:11.840 -of the box we don't have to do anything - -00:02:11.840 --> 00:02:15.040 -and if we did the same here well we have - -00:02:15.040 --> 00:02:15.680 -only - -00:02:15.680 --> 00:02:17.920 -20 colors there's a way to get all the - -00:02:17.920 --> 00:02:19.680 -colors but it's much more involved - -00:02:19.680 --> 00:02:23.040 -but this is not where v term shines - -00:02:23.040 --> 00:02:26.000 -uh we can run all the commands that we - -00:02:26.000 --> 00:02:27.200 -want - -00:02:27.200 --> 00:02:30.480 -h top and cdu - -00:02:30.480 --> 00:02:33.040 -everything runs here also this title - -00:02:33.040 --> 00:02:33.840 -it's a - -00:02:33.840 --> 00:02:36.400 -it's a fairly complicated manipulation - -00:02:36.400 --> 00:02:37.040 -of - -00:02:37.040 --> 00:02:40.879 -the window and it will not work here - -00:02:40.879 --> 00:02:42.319 -it just doesn't work actually now the - -00:02:42.319 --> 00:02:44.640 -terminal is probably messed up - -00:02:44.640 --> 00:02:48.400 -yes so using this external library - -00:02:48.400 --> 00:02:50.959 -removes the burden from the developers - -00:02:50.959 --> 00:02:52.000 -of having to implement - -00:02:52.000 --> 00:02:54.000 -support for all these cape codes we just - -00:02:54.000 --> 00:02:55.360 -use those - -00:02:55.360 --> 00:02:58.480 -so in many ways running veteran - -00:02:58.480 --> 00:03:01.760 -is us running extern inside a max - -00:03:01.760 --> 00:03:04.400 -but it's better than that because since - -00:03:04.400 --> 00:03:05.840 -this is an e-max buffer - -00:03:05.840 --> 00:03:08.879 -we can enjoy a lot of features from - -00:03:08.879 --> 00:03:09.760 -Emacs - -00:03:09.760 --> 00:03:11.920 -as well as a tighter integration with - -00:03:11.920 --> 00:03:13.200 -e-max itself - -00:03:13.200 --> 00:03:16.560 -for example as you see here the title of - -00:03:16.560 --> 00:03:17.599 -my buffer - -00:03:17.599 --> 00:03:20.720 -is from the director I'm in so let's go - -00:03:20.720 --> 00:03:21.760 -to my tmp - -00:03:21.760 --> 00:03:24.799 -the title will change so there's - -00:03:24.799 --> 00:03:26.560 -information being exchanged between v - -00:03:26.560 --> 00:03:28.000 -term and index - -00:03:28.000 --> 00:03:29.760 -and of course the title is not the only - -00:03:29.760 --> 00:03:32.000 -place where information is exchanged - -00:03:32.000 --> 00:03:34.799 -I can find a file and I will be in the - -00:03:34.799 --> 00:03:35.920 -directory - -00:03:35.920 --> 00:03:38.239 -where my terminal is this feature is - -00:03:38.239 --> 00:03:40.000 -also available in nc term - -00:03:40.000 --> 00:03:41.680 -and it works also on b term and it - -00:03:41.680 --> 00:03:43.840 -follows me so if I go to tmp I'll get - -00:03:43.840 --> 00:03:44.720 -the tmp - -00:03:44.720 --> 00:03:48.000 -if I ssh to a remote server it will work - -00:03:48.000 --> 00:03:48.640 -also - -00:03:48.640 --> 00:03:51.120 -on remote servers as well which is a - -00:03:51.120 --> 00:03:53.920 -very nice way to edit files remotely - -00:03:53.920 --> 00:03:55.760 -while we're working on a shelf and - -00:03:55.760 --> 00:03:57.360 -second while vterm - -00:03:57.360 --> 00:03:59.599 -is not an e-lisp interpreter like - -00:03:59.599 --> 00:04:02.159 -initial what we can do is we can - -00:04:02.159 --> 00:04:06.080 -still run inbox functions so for example - -00:04:06.080 --> 00:04:08.319 -that requires some configuration the - -00:04:08.319 --> 00:04:10.159 -term - -00:04:10.159 --> 00:04:12.480 -command message I as you see there's a - -00:04:12.480 --> 00:04:14.000 -higher so what I'm doing - -00:04:14.000 --> 00:04:16.239 -is I'm executing the eagles function I - -00:04:16.239 --> 00:04:17.199 -and I can drop that - -00:04:17.199 --> 00:04:19.840 -and turn it around uh hash function to - -00:04:19.840 --> 00:04:20.320 -run - -00:04:20.320 --> 00:04:24.880 -a-list functions or another one file see - -00:04:24.880 --> 00:04:27.600 -we call this feature message passing and - -00:04:27.600 --> 00:04:28.800 -it requires - -00:04:28.800 --> 00:04:30.880 -some configuration on the emac side as - -00:04:30.880 --> 00:04:32.000 -well as in the shell side - -00:04:32.000 --> 00:04:34.000 -it's important to stress what's the - -00:04:34.000 --> 00:04:35.360 -nature of feature - -00:04:35.360 --> 00:04:37.360 -for instance every time I'm sending a - -00:04:37.360 --> 00:04:39.120 -key binding it's not immediately clear - -00:04:39.120 --> 00:04:40.800 -if my intention is to send it to the - -00:04:40.800 --> 00:04:42.720 -shell or to imax so v term implements - -00:04:42.720 --> 00:04:44.320 -some reasonable defaults - -00:04:44.320 --> 00:04:46.800 -but at the moment it's mainly packaged - -00:04:46.800 --> 00:04:49.120 -to display characters on a screen - -00:04:49.120 --> 00:04:51.199 -so for example if you're using evil the - -00:04:51.199 --> 00:04:53.600 -editing commands in evil will not work - -00:04:53.600 --> 00:04:55.759 -immediately there's some work to be done - -00:04:55.759 --> 00:04:57.840 -and integration can be improved on that - -00:04:57.840 --> 00:04:58.479 -side but - -00:04:58.479 --> 00:05:00.240 -sometimes we really want this to behave - -00:05:00.240 --> 00:05:02.240 -exactly like a imax buffer - -00:05:02.240 --> 00:05:05.440 -we want to be able to search if - -00:05:05.440 --> 00:05:07.039 -if I try to get it to search it will not - -00:05:07.039 --> 00:05:08.880 -work I will send it to the shop so to do - -00:05:08.880 --> 00:05:09.360 -that - -00:05:09.360 --> 00:05:12.400 -we enabled the term copy mode so as you - -00:05:12.400 --> 00:05:12.800 -see -

First, the speed. + +00:01:15.119 --> 00:01:17.119 +Time spent here, 0.6, is essentially + +00:01:17.120 --> 00:01:18.479 +the time that it takes to: + +00:01:18.479 --> 00:01:22.240 +1. convert the Emacs representation of text + +00:01:22.241 --> 00:01:25.040 +into the vterm representation of what is a string, + +00:01:25.041 --> 00:01:27.360 +and 2., into actually displaying that, + +00:01:27.361 --> 00:01:29.520 +and that can take time + +00:01:29.520 --> 00:01:32.240 +if there's fontification involved. + +00:01:32.241 --> 00:01:34.240 +So these are the 0.6 seconds there. + +00:01:34.240 --> 00:01:38.479 +As we say, in ansi-term, that's much more time. + +00:01:38.480 --> 00:01:40.720 +It's much slower. So the terminal will feel + +00:01:40.721 --> 00:01:42.880 +much snappier, much faster. + +00:01:42.880 --> 00:01:46.720 +But that's not the main benefit or the only benefit + +00:01:46.721 --> 00:01:49.759 +of using this external library vterm. + +00:01:49.760 --> 00:01:53.040 +The second big benefit is that + +00:01:53.041 --> 00:01:56.560 +vterm has support for all the escape codes + +00:01:56.560 --> 00:01:58.320 +that xterm has support for, + +00:01:58.321 --> 00:02:01.119 +so vterm is essentially as running xterm + +00:02:01.119 --> 00:02:03.600 +inside an Emacs buffer. So let's see that. + +00:02:03.600 --> 00:02:05.759 +For example, let's start by looking + +00:02:05.760 --> 00:02:08.239 +at the support for colors. + +00:02:08.239 --> 00:02:10.319 +We have support for all the colors out of the box. + +00:02:10.320 --> 00:02:11.840 +We don't have to do anything. + +00:02:11.840 --> 00:02:14.720 +And if we did the same here, well, + +00:02:14.721 --> 00:02:16.800 +we have only 20 colors. + +00:02:16.801 --> 00:02:18.239 +There's a way to get all the colors, + +00:02:18.240 --> 00:02:19.680 +but it's much more involved. + +00:02:19.680 --> 00:02:23.040 +But this is not where vterm shines. + +00:02:23.040 --> 00:02:27.200 +We can run all the commands that we want. + +00:02:27.200 --> 00:02:31.440 +htop, ncdu, everything runs here. + +00:02:31.441 --> 00:02:35.519 +Also this title, it's a fairly complicated + +00:02:35.520 --> 00:02:37.920 +manipulation of the window + +00:02:37.921 --> 00:02:40.879 +and it will not work here. + +00:02:40.879 --> 00:02:42.000 +It just doesn't work actually. + +00:02:42.001 --> 00:02:46.160 +Now the terminal is probably messed up. Yes. + +00:02:46.161 --> 00:02:48.400 +So using this external library + +00:02:48.400 --> 00:02:50.959 +removes the burden from the developers + +00:02:50.959 --> 00:02:52.319 +of having to implement support + +00:02:52.320 --> 00:02:53.280 +for all the escape codes. + +00:02:53.281 --> 00:02:55.360 +We just use those. + +00:02:55.360 --> 00:02:58.480 +So in many ways, running vterm + +00:02:58.480 --> 00:03:01.760 +is running xterm inside Emacs, + +00:03:01.760 --> 00:03:04.159 +but it's better than that because, + +00:03:04.160 --> 00:03:05.840 +since this is an Emacs buffer, + +00:03:05.840 --> 00:03:09.760 +we can enjoy a lot of features from Emacs + +00:03:09.760 --> 00:03:11.360 +as well as a tighter integration + +00:03:11.361 --> 00:03:13.200 +with Emacs itself. + +00:03:13.200 --> 00:03:15.840 +For example, as you see here, + +00:03:15.841 --> 00:03:20.239 +the title of my buffer is from the directory I'm in. + +00:03:20.240 --> 00:03:21.760 +So let's go to my tmp. + +00:03:21.760 --> 00:03:23.440 +The title will change. + +00:03:23.441 --> 00:03:25.920 +So there's information being exchanged + +00:03:25.921 --> 00:03:28.000 +between vterm and Emacs. + +00:03:28.000 --> 00:03:30.000 +And of course, the title is not the only place + +00:03:30.001 --> 00:03:32.000 +where information is exchanged. + +00:03:32.000 --> 00:03:35.920 +I can find a file and I will be in the directory + +00:03:35.920 --> 00:03:37.680 +where my terminal is. + +00:03:37.681 --> 00:03:40.000 +This feature is also available in ansi-term, + +00:03:40.000 --> 00:03:41.360 +and it works also on vterm, + +00:03:41.361 --> 00:03:43.440 +and it follows me. So if I go to tmp, + +00:03:43.441 --> 00:03:44.720 +I'll get the tmp. + +00:03:44.720 --> 00:03:47.120 +If I ssh to a remote server, + +00:03:47.121 --> 00:03:50.239 +it will work also on remote servers as well, + +00:03:50.240 --> 00:03:53.920 +which is a very nice way to edit files remotely + +00:03:53.920 --> 00:03:55.599 +while we're working on a shell. + +00:03:55.600 --> 00:03:59.280 +And second, while vterm is not an Elisp interpreter + +00:03:59.281 --> 00:04:01.200 +like eshell, what we can do is + +00:04:01.201 --> 00:04:04.720 +we can still run Emacs functions. + +00:04:04.721 --> 00:04:06.080 +So for example... + +00:04:06.081 --> 00:04:08.000 +that requires some configuration. + +00:04:08.001 --> 00:04:11.599 +vterm command (message "hi") + +00:04:11.600 --> 00:04:13.120 +as you see there's a "hi" here. + +00:04:13.121 --> 00:04:14.959 +So what I'm doing is I'm executing + +00:04:14.960 --> 00:04:16.239 +the Elisp function hi. + +00:04:16.239 --> 00:04:18.959 +I can drop that and turn it around, + +00:04:18.960 --> 00:04:21.600 +hash function to run Elisp functions. + +00:04:21.601 --> 00:04:24.880 +Or another one, find-file, same. + +00:04:24.880 --> 00:04:27.360 +We call this feature "message passing," + +00:04:27.361 --> 00:04:30.000 +and it requires some configuration + +00:04:30.001 --> 00:04:32.000 +on the Emacs side as well as in the shell side. + +00:04:32.000 --> 00:04:33.440 +It's important to stress + +00:04:33.441 --> 00:04:35.360 +what's the nature of vterm. + +00:04:35.360 --> 00:04:37.919 +For instance, every time I'm sending a key binding, + +00:04:37.920 --> 00:04:40.000 +it's not immediately clear if my intention is + +00:04:40.001 --> 00:04:41.840 +to send it to the shell or to Emacs. + +00:04:41.841 --> 00:04:44.320 +So vterm implements some reasonable defaults, + +00:04:44.320 --> 00:04:46.800 +but at the moment it's mainly packaged + +00:04:46.800 --> 00:04:49.120 +to display characters on a screen. + +00:04:49.120 --> 00:04:50.720 +So for example, if you're using evil, + +00:04:50.721 --> 00:04:52.639 +the editing commands in evil + +00:04:52.640 --> 00:04:54.080 +will not work immediately. + +00:04:54.081 --> 00:04:55.759 +There's some work to be done + +00:04:55.759 --> 00:04:58.160 +and integration can be improved on that side, + +00:04:58.161 --> 00:05:00.240 +but sometimes we really want this to behave + +00:05:00.240 --> 00:05:02.240 +exactly like a Emacs buffer. + +00:05:02.240 --> 00:05:03.680 +We want to be able to search. + +00:05:03.681 --> 00:05:06.639 +If I try to get it to search, + +00:05:06.640 --> 00:05:07.280 +it will not work. + +00:05:07.281 --> 00:05:08.400 +I will send it to the shell. + +00:05:08.401 --> 00:05:11.919 +So to do that, we enabled vterm copy mode. + +00:05:11.920 --> 00:05:14.720 +As you see, copy mode, and now this buffer + +00:05:14.721 --> 00:05:17.039 +is essentially a fundamental buffer. + +00:05:17.039 --> 00:05:21.120 +I can move around. I can search. + +00:05:21.120 --> 00:05:25.520 +So it must have... I can do everything I want. + +00:05:25.521 --> 00:05:26.479 +And there are additional features. + +00:05:26.480 --> 00:05:30.560 +For example, I can jump around all the prompts. + +00:05:30.561 --> 00:05:32.639 +I find this extremely useful, + +00:05:32.639 --> 00:05:35.039 +because I can copy updates from my programs. + +00:05:35.040 --> 00:05:38.320 +What I always have to do is + +00:05:38.321 --> 00:05:41.520 +I have to Google some errors. + +00:05:41.521 --> 00:05:43.120 +So what I do is I select that + +00:05:43.120 --> 00:05:45.120 +and I have my keybinding in Emacs conf, + +00:05:45.121 --> 00:05:48.479 +and I'm Googling what I have to Google. + +00:05:48.480 --> 00:05:51.120 +So this is very nice and if I... + +00:05:51.121 --> 00:05:52.639 +now that I have selected something, + +00:05:52.640 --> 00:05:53.840 +if I just press return, + +00:05:53.841 --> 00:05:56.400 +I will go back to my normal editing mode + +00:05:56.401 --> 00:06:00.160 +with the text copied, so I can paste it back. + +00:06:00.161 --> 00:06:02.720 +So it's a quick way to interact with copy + +00:06:02.721 --> 00:06:05.840 +and interact with the output of a buffer. + +00:06:05.841 --> 00:06:09.120 +So finally, let's discuss how to actually use vterm. + +00:06:09.121 --> 00:06:10.560 +Let's circle back, let's go, + +00:06:10.560 --> 00:06:12.400 +and let's look at the GitHub repo + +00:06:12.400 --> 00:06:14.000 +where development is happening. + +00:06:14.001 --> 00:06:15.520 +vterm is available in MELPA, + +00:06:15.520 --> 00:06:17.759 +but since it's leveraging the power + +00:06:17.760 --> 00:06:18.960 +of an external module, + +00:06:18.960 --> 00:06:20.479 +you must have Emacs compiled + +00:06:20.480 --> 00:06:22.000 +with support for modules, + +00:06:22.000 --> 00:06:25.600 +and many distros like Ubuntu, Debian, + +00:06:25.600 --> 00:06:26.880 +that's not there. So you have to + +00:06:26.881 --> 00:06:29.199 +get Emacs with support for modules: + +00:06:29.200 --> 00:06:31.360 +compiling or getting images somewhere else. + +00:06:31.361 --> 00:06:33.840 +And also, the first time you are going to use this, + +00:06:33.840 --> 00:06:38.960 +which works only on Mac or GNU Linux systems, + +00:06:38.961 --> 00:06:41.759 +Emacs will try to find and compile this module, + +00:06:41.759 --> 00:06:44.240 +so it's important. This requirement is important. + +00:06:44.241 --> 00:06:46.400 +If you're using Windows, well, + +00:06:46.401 --> 00:06:49.199 +it's not available and will not work. + +00:06:49.199 --> 00:06:53.440 +So to conclude, I want to just advertise this page. + +00:06:53.440 --> 00:06:56.240 +If you have problems, look at the issues + +00:06:56.240 --> 00:06:58.240 +and open an issue in case. + +00:06:58.241 --> 00:06:59.199 +We'll try to help you. + +00:06:59.200 --> 00:07:00.800 +We are very excited about vterm, + +00:07:00.800 --> 00:07:02.639 +and I think it's a transformative +

and then you +00:01:45.921 --> 00:01:49.520 +So the basics of object orientation -00:01:53.759 --> 00:01:55.840 -instantiate that class and these +00:01:49.521 --> 00:01:50.560 +in most languages are:

+00:02:28.561 --> 00:02:31.680 +Emacs Lisp libraries, this relationship -00:02:34.080 --> 00:02:37.599 -in that data slots and +00:02:31.681 --> 00:02:34.080 +is turned on its head a little bit, -00:02:37.599 --> 00:02:40.239 -uh and instance methods are defined +00:02:34.080 --> 00:02:39.599 +in that data slots and instance methods -00:02:40.239 --> 00:02:41.360 -outside of the +00:02:39.600

00:02:49.920 +but first I want to talk about -00:02:49.840 --> 00:02:51.760 -about how news does this and in order to +00:02:49.921 --> 00:02:51.280 +how Gnus does this. -00:02:51.760 --> 00:02:54.319 -do that we are going to go deep into +00:02:51.281 --> 00:02:52.160 +In order to do that, -00:02:54.319 --> 00:02:57.440 -the darkest corner of the new co source +00:02:52.161 --> 00:02:54.319 +we are going to go deep into -00:02:57.440 --> 00:02:59.879 -code tree to a library called +00:02:54.319 --> 00:02:55.760 +the darkest corner -00:02:59.879 --> 00:03:02.879 -nno.l very cryptically +00:02:55.761 --> 00:02:58.080 +of the Gnus source code tree -00:03:02.879 --> 00:03:05.040 -titled uh library and when we open it up +00:02:58.081 --> 00:03:01.440 +to a library called nnoo.el, -00:03:05.040 --> 00:03:06.800 -we find +00:03:01.441 --> 00:03:04.080 +very cryptically-titled library, -00:03:06.800 --> 00:03:09.519 -a library with no code comments and +00:03:04.081 --> 00:03:06.800 +and when we open it up, we find -00:03:09.519 --> 00:03:11.040 -almost no doc strings +00:03:06.800 --> 00:03:09.280 +a library with no code comments + +00:03:09.281 --> 00:03:11.040

-00:03:24.480 --> 00:03:25.760 -of back ends for news +00:03:23.921 --> 00:03:25.760 +different kinds of backends for Gnus, -00:03:25.760 --> 00:03:27.280 -and then those back ends can be +00:03:25.760 --> 00:03:26.799 +and then those backends -00:03:27.280 --> 00:03:29.760 -instantiated as individual +00:03:26.800 --> 00:03:30.879 +can be instantiated as individual servers.

+00:03:32.480 --> 00:03:34.319 +you're supposed to use two macros, -00:03:33.360 --> 00:03:36.000 -two macros which you can see here one is +00:03:34.320 --> 00:03:35.680 +which you can see here. -00:03:36.000 --> 00:03:36.640 -called def +00:03:35.681 --> 00:03:37.280 +One is called defvoo, -00:03:36.640 --> 00:03:39.599 -vu and one is called defu and if you +00:03:37.281 --> 00:03:39.440 +and one is called deffoo. -00:03:39.599 --> 00:03:41.280 -look at the definitions the definitions +00:03:39.441 --> 00:03:40.400 +If you look at the definitions, -00:03:41.280 --> 00:03:43.280 -look pretty simple here def vu basically +00:03:40.401 --> 00:03:41.920 +the definitions look pretty simple. -00:03:43.280 --> 00:03:45.440 -turns into a def var +00:03:41.921 --> 00:03:45.440 +Here, defvoo basically turns into a defvar 00:03:45.440 --> 00:03:49.040 -and foo turns into a defund +and foo turns into a defun. 00:03:49.040 --> 00:03:52.239 -and along with those basic definitions +Along with those basic definitions, 00:03:52.239 --> 00:03:55.760 -the library also does some registration +the library also does some registration, 00:03:55.760 --> 00:03:58.720 -memoization caching of those variables - -00:03:58.720 --> 00:04:00.080 -it saves them in the structure - -00:04:00.080 --> 00:04:01.840 -for later use so that we know that those - -00:04:01.840 --> 00:04:03.360 -are meant to be - -00:04:03.360 --> 00:04:05.280 -uh attributes and methods that are used +memoization, caching of those variables. -00:04:05.280 --> 00:04:06.640 -with instances +00:03:58.720 --> 00:04:00.879 +It saves them in the structure for later use, -00:04:06.640 --> 00:04:08.000 -with server instances but you can see +00:04:00.880 --> 00:04:03.360 +so that we know that those are meant to be -00:04:08.000 --> 00:04:09.280 -that there's no server instance +00:04:03.360 --> 00:04:04.799 +attributes and methods -00:04:09.280 --> 00:04:10.560 -definition here there's no +00:04:04.800 --> 00:04:06.640 +that are used with instances, -00:04:10.560 --> 00:04:13.200 -like no nothing these are top level +00:04:06.640 --> 00:04:07.519 +with server instances. -00:04:13.200 --> 00:04:14.239 -these are top level +00:04:07.520 --> 00:04:08.159 +But you can see that -00:04:14.239 --> 00:04:18.160 -definitions so really data attributes +00:04:08.160 --> 00:04:10.000 +there's no server instance definition here. -00:04:18.160 --> 00:04:18.639 -for +00:04:10.001 --> 00:04:12.159 +There's no, like, no nothing. -00:04:18.639 --> 00:04:22.000 -new servers and +00:04:12.160 --> 00:04:14.799 +These are top-level definitions, -00:04:22.000 --> 00:04:23.840 -methods or functions that operate on +00:04:14.800 --> 00:04:20.239 +so really, data attributes for new servers -00:04:23.840 --> 00:04:25.440 -those instances are completely +00:04:20.240 --> 00:04:23.040 +and methods or functions -00:04:25.440 --> 00:04:28.400 -separate mechanisms they don't really +00:04:23.041 --> 00:04:24.639 +that operate on those instances -00:04:28.400 --> 00:04:29.600 -have anything to do with each other they +00:04:24.640 --> 00:04:27.840 +are completely separate mechanisms. -00:04:29.600 --> 00:04:31.680 -don't belong to the same data structures +00:04:27.841 --> 00:04:29.040 +They don't really have anything to do -00:04:31.680 --> 00:04:37.120 -so how do they work follow me +00:04:29.041 --> 00:04:29.520 +with each other. -00:04:37.120 --> 00:04:39.520 -aka methods and attributes these are all +00:04:29.521 --> 00:04:31.680 +They don't belong to the same data structures. -00:04:39.520 --> 00:04:41.360 -the things I just said +00:04:31.680 --> 00:04:34.080 +So how do they work? -00:04:41.360 --> 00:04:44.479 -so when you define a +00:04:34.081 --> 00:04:37.120 +Follow me. deffoo and defvoo, -00:04:44.479 --> 00:04:48.560 -a backend type +00:04:37.120 --> 00:04:38.960 +aka methods and attributes, -00:04:48.560 --> 00:04:51.199 -in noose what you get is this a +00:04:38.961 --> 00:04:41.360 +these are all the things I just said. -00:04:51.199 --> 00:04:52.400 -definition a list +00:04:41.360 --> 00:04:50.240 +So when you define a a backend type in Gnus, -00:04:52.400 --> 00:04:54.080 -and it'll say there is such a back end +00:04:50.241 --> 00:04:52.400 +what you get is this: a definition, a list. -00:04:54.080 --> 00:04:55.520 -as nnml +00:04:52.400 --> 00:04:55.520 +It'll say, there is such a backend as nnml, 00:04:55.520 --> 00:04:58.880 -and these are its uh data attributes +and these are its data attributes -00:04:58.880 --> 00:04:59.520 -that any +00:04:58.880 --> 00:05:01.039 +that any given instance can have, -00:04:59.520 --> 00:05:01.840 -given instance can have and then these +00:05:01.040 --> 00:05:04.720 +and then these are the functions or methods -00:05:01.840 --> 00:05:02.960 -are +00:05:04.721 --> 00:05:06.880 +that are defined to operate on -00:05:02.960 --> 00:05:04.960 -the functions or methods that are +00:05:06.880 --> 00:05:08.240 +an instance of this backend, -00:05:04.960 --> 00:05:06.880 -defined to operate on +00:05:08.241 --> 00:05:09.600 +so a server that belongs to -00:05:06.880 -->

least we have this data here. -00:05:11.440 --> 00:05:13.360 -backend so at least we have this data +00:05:13.601 --> 00:05:16.080 +That's handy.
