[00:00.000 --> 00:09.380]  Andrei, he's going to talk about a new of them, I went through this deck, it's actually
[00:09.380 --> 00:10.380]  really cool.
[00:10.380 --> 00:13.460]  Before you go on, I need to give you this.
[00:13.460 --> 00:14.460]  Yeah.
[00:14.460 --> 00:26.420]  No, we need this one for the projection, so here we go.
[00:26.420 --> 00:30.500]  One, one, one.
[00:30.500 --> 00:32.220]  Can you hear me?
[00:32.220 --> 00:33.220]  Can you hear me?
[00:33.220 --> 00:34.220]  Yes.
[00:34.220 --> 00:35.220]  Cool.
[00:35.220 --> 00:36.220]  I can...
[00:36.220 --> 00:39.100]  I think I can fix it.
[00:39.100 --> 00:44.340]  I can use it, so let's start, so we don't have time.
[00:44.340 --> 00:45.340]  Okay.
[00:45.340 --> 00:53.180]  Today I will talk about Rust and NeoVim, so if you see something inaccurate, I'm new
[00:53.180 --> 00:57.100]  in Rust, so please don't judge me too much.
[00:57.100 --> 00:59.060]  A little bit about me.
[00:59.060 --> 01:05.980]  I'm Andrei, I'm from Ukraine, now living in Vienna, in Austria, I do a lot Go, Python,
[01:05.980 --> 01:14.020]  I love gymnastics on other stuff, I love speaking, I just dig talk in another room, so I just
[01:14.020 --> 01:15.020]  move forward.
[01:15.020 --> 01:16.020]  Cool.
[01:16.020 --> 01:17.020]  Let's start.
[01:17.020 --> 01:29.740]  So NeoVim is the most loved editor in 2021 and in 2022, and Rust is the most loved language
[01:29.740 --> 01:36.980]  in 2022, so I feel it's a win-win, it's the best combination you can ever see.
[01:36.980 --> 01:41.060]  So can you raise your hand very quick, who use like NeoVim or something?
[01:41.060 --> 01:43.060]  Oh, it's my audience.
[01:43.060 --> 01:44.060]  Nice, nice.
[01:44.060 --> 01:45.060]  Nice.
[01:45.060 --> 01:46.860]  So why this for you?
[01:46.860 --> 01:54.820]  If you like me, love to spend all the day, weekends, configuring my development environment,
[01:54.820 --> 01:58.180]  please don't tell it to my boss.
[01:58.180 --> 02:04.100]  And since all of you using NeoVim, I think you know how to quick from Vim, right?
[02:04.100 --> 02:06.500]  No need to explain, cool?
[02:06.500 --> 02:09.900]  So sugar smoking also, cool.
[02:09.900 --> 02:16.740]  So first things first, NeoVim is just a fork of Vim, which is focused on like extensibility
[02:16.740 --> 02:17.740]  and usability.
[02:17.740 --> 02:26.140]  One of the examples is they injected or added ability to write plugins in Lua, which is great.
[02:26.140 --> 02:39.060]  And since 0.5, as you know, NeoVim supports LSP client framework, all good, all good.
[02:39.060 --> 02:45.340]  This means NeoVim can work as a client to LSP servers like Rust Analyzer and building
[02:45.340 --> 02:46.700]  other tools.
[02:46.700 --> 02:53.740]  So to prove my words, yeah, if you open NeoVim and type help LSP, it's like inside editor,
[02:53.740 --> 02:55.260]  which is nice.
[02:55.260 --> 02:58.340]  And you can read what you can do.
[02:58.340 --> 03:07.780]  So and for some of you who don't know what is LSP, very quick, so LSP is like a bridge.
[03:07.780 --> 03:13.580]  So now you can focus on developers of language servers, can focus on developing language
[03:13.580 --> 03:19.300]  service, and developers of editors can focus on editors.
[03:19.300 --> 03:21.700]  And it's like win-win again.
[03:21.700 --> 03:28.460]  Because previously it was like this, you need to write a tool, which format your code or
[03:28.460 --> 03:35.300]  whatever, it parse all three and depend on language, you can integrate it.
[03:35.300 --> 03:41.660]  And jumping between languages is hard, that's why it's nice when you have this LSP.
[03:41.660 --> 03:46.580]  So quick start, I assume you know how to install NeoVim.
[03:46.580 --> 03:55.500]  So if you never did it before, I highly recommend to start with this one file config, which is
[03:55.500 --> 03:58.740]  here and put it in your config location.
[03:58.740 --> 04:06.540]  What it does, it's very small, and it has few important plugins, which helps you to
[04:06.540 --> 04:08.060]  try it out.
[04:08.060 --> 04:14.660]  And I highly recommend to use it because it's easy to start doing something small and simple
[04:14.660 --> 04:20.980]  rather than starting like, okay, I need like lots of files, I need to repo for all my configs,
[04:20.980 --> 04:21.980]  et cetera.
[04:21.980 --> 04:26.980]  And as soon as you know more, you can refactor it.
[04:26.980 --> 04:35.940]  So in this file, include this new Mason plugin, which helps you to install language servers,
[04:35.940 --> 04:42.460]  which is handy, because you can do it directly from NeoVim, and it will install binaries
[04:42.460 --> 04:51.980]  directly to NeoVim standard pass, and when you start NeoVim, it will add this like location,
[04:51.980 --> 04:56.580]  so NeoVim and tooling will can communicate with these binaries.
[04:56.580 --> 05:08.860]  And it supports LSP, so also for debuggers, for linters, for motors, sorry, next.
[05:08.860 --> 05:16.580]  So when you're done, you can see this after complete, which is great.
[05:16.580 --> 05:19.500]  Another interesting feature you can do after imports.
[05:19.500 --> 05:25.540]  So for example, if you use hash map, but you forget to import it, I usually do it.
[05:25.540 --> 05:26.820]  It's very nice.
[05:26.820 --> 05:35.100]  And if you bind this code action, it will print you like different depend on which part
[05:35.100 --> 05:36.820]  of code you are.
[05:36.820 --> 05:45.740]  If it has any connections, for example, import hash map, you can type and import it automatically,
[05:45.740 --> 05:46.900]  and that's it.
[05:46.900 --> 05:49.060]  It's very cool.
[05:49.060 --> 05:50.340]  Same with rename.
[05:50.340 --> 05:57.220]  So now all haters of Vim can't say that you're renaming using grep, so you can rename using
[05:57.220 --> 06:03.420]  syntax tree, be smart, and using entire code base.
[06:03.420 --> 06:04.420]  And that's it.
[06:04.420 --> 06:11.780]  Yeah, I supposed to make a juice, but since we decided to reduce talk, I just have a picture.
[06:11.780 --> 06:15.900]  If you like me, forget your key maps, because you have tons.
[06:15.900 --> 06:21.540]  You can just use this nice plug-in telescope key maps and just remind yourself, oh, shit,
[06:21.540 --> 06:23.180]  just fuzzy find this.
[06:23.180 --> 06:24.780]  So very handy.
[06:24.780 --> 06:32.380]  For example, I forget LSP references, so I can find how to run it.
[06:32.380 --> 06:39.100]  And again, this LSP references is more or less language agnostic.
[06:39.100 --> 06:43.860]  It's extension of telescope, which like get it and show you.
[06:43.860 --> 06:51.060]  You can do hover documentation, you can do, I don't know, signature help, and many more.
[06:51.060 --> 06:56.260]  Other features, which I unfortunately can't cover in this short talk, but I highly recommend
[06:56.260 --> 07:00.180]  you go to this page and see how smart Rust Analyzer.
[07:00.180 --> 07:08.500]  It can do very nice refactoring, like, I don't know, apply Moore's law for your binary logic,
[07:08.500 --> 07:14.740]  replace some patterns, et cetera.
[07:14.740 --> 07:17.740]  So I'm personally using big config.
[07:17.740 --> 07:19.580]  You can, if you want, you can check it.
[07:19.580 --> 07:22.300]  It's more organized because it's really big.
[07:22.300 --> 07:25.300]  It's not one file.
[07:25.300 --> 07:31.740]  And if you need refresh knowledge about WIM, there are two really good books I ever read
[07:31.740 --> 07:36.820]  about editors, and you can play a little bit with WIM golf.
[07:36.820 --> 07:39.740]  If you never try, I highly recommend.
[07:39.740 --> 07:46.340]  Yeah, and a few references of guys which inspire me to use Neo WIM a lot.
[07:46.340 --> 07:48.220]  And thank you.
[07:48.220 --> 07:49.220]  Questions.
[07:49.220 --> 07:50.220]  Yeah, thanks.
[07:50.220 --> 07:51.220]  Questions.
[07:51.220 --> 07:52.220]  Yeah, thanks.
[07:52.220 --> 07:53.220]  Yeah, thanks.
[07:53.220 --> 07:54.220]  Yeah, thanks.
[07:54.220 --> 07:55.220]  Thanks.
[07:55.220 --> 07:56.220]  Thanks.
[07:56.220 --> 07:57.220]  Thanks.
[07:57.220 --> 07:58.220]  Thanks.
[07:58.220 --> 07:59.220]  Thanks.
[07:59.220 --> 08:00.220]  Thanks.
[08:00.220 --> 08:01.220]  Thanks.
[08:01.220 --> 08:02.220]  Thanks.
[08:02.220 --> 08:03.220]  Thanks.
[08:03.220 --> 08:04.220]  Thanks.
[08:04.220 --> 08:05.220]  Thanks.
[08:05.220 --> 08:06.220]  Thanks.
