[@steveoc64]

Probably the most important playlist on the whole internet. Chris has singlehandedly saved our entire civilization from sliding into Idiocracy. Long live text mode, long live neovim, and long live pure Lua configs that are actually readable. Thx

[@yogxoth1959]

I’m switching my whole config to Lua too. I’ve never had any desire to learn vimscript, and I can use Lua in other areas as well.

[@tjex]

update for users doing fresh setup. 06:00 the maintainer of nvim-lsp-installer has superseeded the plugin with a new plugin called Mason. It's the same idea, just re written etc. So install that. All of chris' videos to do with lsp will still work for you (as the new plugin has the same approach, funcationality, etc)

[@avradeep]

Chris please add this to the description as well. I fumbled around for like an hour till I found this comment.

[@andreimotinga1826]

still didnt work for me. played with it for a bit - but in the end couldnt make it work for .jsx file. no LSP there.

[@dabzilla05]

As always, your content directly mirrors my own neovim journey. I was just doing all this research a few nights ago and it is really good to see another person using the same perspective of nvim-lsp-install, lsp-config, and lsp-csp with list-install as the wrapper. Appreciate the content, it makes a significant difference in an open source ecosystem where we don't have a huge company pumping out tutorial videos with every new release.

[@jetandarkumar8034]

hey Could you help me with something?

[@michaelcarnevale5620]

hey man just wanted to let you know i consider you the definitive source when i need to set up Vim or whatever other stuff ... you are clear, detailed but not too detailed, well organized, and likable (i appreciate that you don't put on a character, tho i do wonder how you're feeling based on your tone of voice) all in all man just wanted to say thanks your hard work has helped me and others

[@rdandnayak]

You are excellent teacher, every piece explained is to the point, no nonsense. Thanks for making this series

[@nikob381]

Man thank you so much for these videos. Every other resource seems to go down the COC route so it's nice to finally see an alternative setup that happens to match much of what I'd already put together myself so far. This playlist is amazing.

[@9bnmadden]

10xing my understanding of NVIM with this series! This is so awesome. Your hard work on all this is appreciated.

[@VitaliiPatsaliuk]

This is one of the best tutorial I have been watching on KZbin. Thank you! To be honest I faced with one problem when trying set root_pattern("Gemfile", ".git", ".") this config can help setup server for ruby (solargraph) to work correctly with rvm.

[@BigEyesLuigi1]

Thank you very much for creating this playlist. This is extremely useful for beginners like me to make Neovim behaves more like an IDE :)

[@moslastar86]

Thanks for the series! I believe the 'M' is for module.

[@ruchejok4946]

Dude, you're godsent. Thank you, thank you, thank you for your amazing playlist, and for all the hard work you've put into creating your repo and teaching a bunch of randos online how to turn neovim into an amazing, personolized IDE. I've been doing a lot of work in Inteliji Idea, and though it is very good in its niche, I grew tired of all the bloat, lags, and endless indexing. This, what you've done to promote neovim to people, is truly great. 10/10

[@undertheradar4645]

Man, this tutorial, playlist, channel.. is genuinely invaluable

[@r0yce]

This is probably the most important video. And since it has gone somewhat obsolete it would be great if you made another video on this. I know your repo has the latest code but your explanations are really helpful.

[@Benjigga]

The Easter egg at the end is really useful. Thanks!

[@arlaxia]

Even a year after, this playlist is helping me learn how to configure neovim so good.

[@jitessh]

Thank you for sharing this knowledge. I love this series.

[@dhananjaym2311]

Thank you very much for creating this playlist. This is extremely useful!!

[@kasen7442]

13:28 For anyone having problems with line diagnostics keep in mind that show_line_diagnostics is deprecated so in order to make it work you should change line 79 to something like: 'lua vim.diagnostic.open_float(0, { scope = "line", border = "rounded" })'

[@youdontknowme2508]

Thanks a lot. I was having the exact issue.

[@xGshikamaru]

I wish I saw your comment earlier, cause I fixed it myself but to do that I had to go through the neovim repo, find that commit 06064411ea7ff825aed3d4e01207914ed61d7ee79d4411ea7ff825aed3d4e01207914ed61d7ee79d broke the API on october 19th. I’m confused, because neovim-from-scratch was updated to work with neovim 0.8.0 which was released on september 30th and I was running 0.8.1. I downloaded 0.8.0 appimage and it seems the breaking change is also there. Not really sure what’s going on with neovim releases, or if we could make a pull request for neovim-from-scratch. BTW you can omit the bufnr and just call open_float({ scope = "line", border = "rounded })

[@crytex1747]

This whole series is so awesome!

[@himanshutripathi7441]

Thank you for these videos. Best LSP tutorial

[@kristun216]

Just wanted to say thank you. After 64 commits, discovering LSPs and trying out lazygit. I am ready to switch full-time to Neovim. I really appreciate it man, thank you so much.

[@ostapsulyk]

It actually worked!!!!!!!! ahahhha thats awesome, thank you. Cant wait for next video

[@josefhula9811]

Thanks a lot, great comprehensive and explanatory video

[@dhananjayraut]

[@r-iliass9587]

Just at the right time!

[@evadeflow]

_Damn._ Neovim has gotten _super_ sexy in the four years since I last looked at it seriously. After this series, I'm hooked! Thanks for making it so painless to get up and running.

[@stoicfloor]

So happy to be moving away from CoC. Thanks Chris!

[@kenng3271]

Very good tutorial, thanks for creating it

[@dylanelens]

One day when I am past being a student I will remember you. Really appreciate this super sexy setup.

[@bendirval3612]

This is a maddening amount of configuration. The old vimscript plugins just require a couple of variables to be set for each plugin, at most. I don't normally shy away from config work, but these lua plugins are just too much work--they don't seem ready for ordinary usage. The deeper I get into this project, the more unwieldy it gets.

[@penguin1714]

It would be super awesome if you went through and showed how to configure lsp on a per project basis. For example, in C, I often need to use different toolchains. The only way to do this currently is to change my clangd opts being passed to the lsp-installer setup function every time I need to change this. I've added more information on a github issue (#48) on your neovim from scratch repo (posting the link here removes my comment =( ) Thanks a bunch for this series. Really helpful

Does anyone have problems with the help of the selected suggestion? When I Control+j/k to choose an option I get: "... bad argument #1 to 'min' (number expected, got nil)" It's the only thing that I could not solve!

[@MrZombieSwamp]

how can I configure the LSP to use a virtual environment for python??

[@djcardwellai]

hey chris I'm trying to split with :Vex but am unable to do so. Can you help me out here?

[@rohitsrao]

As of 19 Oct 2021, it is recommended to use cmp_nvim_lsp.default_capabilities(capabilities) instead of cmp_nvim_lsp.update_capabilities(capabilities) as the latter will be deprecated

[@jlysiak]

Cool video series! Thx a lot! Btw, I have a quesion. Can we somehow get rid of `user.` prefix when we are inside lsp package? That's the only thing which annoys me a lot :)

[@creative-commons-videos]

how can i open another project without closing neovim, like in vscode i can click open folder and choose any other project director to open

[@Aucacoyan]

Hi! Awesome video, as always, I'm binging all the content. Can you please update this video for mason? because the repo it's now updated on the branch LSP. Thanks!

[@ebiscaia]

Hi Chris, Any chance of updating this tutorial as nvim-lsp-installer will not be maintained anymore? In my case my diagnostics are messed up (just first occurrence appears). It seems like it is ignoring some parts of the handler file. Thanks

[@danhenri3310]

anyone getting an "attempt to index a boolean value" about their lsp/init.lua file for the "require("user.lsp.handlers).setup()" line? Can't figure out what's wrong but I assume something with the setup function?

[@hechuan5075]

i just had the same problem. i figured it out by inserting a print statment before every function call in lsp.handlers. turns out i forgot to install cmp-nvim-lsp

[@tony-ma]

can you please also do a vedio on your latest terminal configure?

[@reubenpopp2006]

So, one thing I noticed while getting this working is that I have to be typing a method name to get the signature/docs to show. Is there a way to hover on a method (eg, go's fmt.Printf) and have it display the text without having to do a substitution on Printf?

[@pojeb2]

Hi Chris i need your help. I'm traying to run dartls as lsp server using nvim-lsp-installer. After instalation using 'LspInfo", i see information: Other clients that match the filetype: dart. I dont know what i'm doing wrong , why dartls client is not attached to my buffer. thank you in advance for your help.

[@flywithoutwingss]

Hi, did anyone make work emmet-ls with react? Can't find the way to configure.

[@matthewgreen9810]

At 14:40, when highlight is on the keyword 'function', it highlights the corresponding 'end'.

[@56phil020244]

Excellent series, Chris. I have a LSP question. Thanks to lsp-zero and Mason, I'm set up for C++. There's one minor issue, it's flagging a correct statement as an error. I think that's because I'm using c++20, and clangd is using an earlier standard. How do I get clangd to use C++20? Thank you.

[@TorresHerminio]

Hey Chris, first thing first, I like to say thank you for doing this playlist. Also, I like to ask you after I set up things for LSP, my vim it's opening very slowly, this is right? Besides I try to set up things to work with elixirls, but I don't know if it is working properly, can you give me a hand? I can share with you my files, thank you again!

[@TheRealSh1fu]

Can you make a video updating the LSP Config using mason.nvim instead? nvim-lsp-installer is no longer being maintained. Thanks!

[@StephenMolloyGoogle]

I have the rust-analyser binary installed on my PATH, and I've installed it so that LspInstallInfo confirms it's there. I've added it to the list of servers in configu.lua, but it still isn't connecting when I open a rust file. What am I doing wrong?

[@StephenMolloyGoogle]

Of course, as soon I as I write this, I figure it out. I typo'd the name. "rust_analyzer", not "rust_analyser". Doh.

[@RotAdhs]

First of all, thank you for helping us out on our nvim adventures. Does anyone know how he opens :Vexplore at 06:53 ? Even looking at the keystrokes and using the nvim configurations files I do not understand how the new panel resizes to less than 50% of the window.

[@RotAdhs]

Hello, it's me again. I found out why I was facing that issue earlier. In the video he uses the "nvimtree" plugin which I wasn't using in my nvim configuration. Nvimtree is introduced in branch 12-nvimtree and I was using 06-LSP. He's just pressing e to open up the nvimtree panel (where leader is "").

[@LongestYardstick]

I've seen cpp programmers use m_VariableName to denote "member" fields or whatever, maybe the M table is reminiscent of that?

[@m3hdim3hdi]

When I open a .js file with neovim i get this error message: "Autostart for tsserver failed: matching root directory not detected" and when i check LspInfo i get this: "Unable to find executable. Please check your path and ensure the server is installed". and python and html completion works perfectly, can you help me please?

[@khanriza]

Had the same problem, don't know what I did to fix it though :D

[@daniilkasatkin8170]

You need to install TS to root directory of npm

I'm having trouble with pyright lsp, local modules are not recognized (from the project directory) and I'm using the local system interpreter (python 3.9), any help ? Looked into nvim-lsp-config server_configurations.md but didn't help. Thanks!

[@WeAreTeamNovus]

Did you figure it out? In the same boat.

[@Jantalus]

@@WeAreTeamNovus Didn't but it points to "single file mode" when you use :LspInfo, was going to look (recommended via nvim forum) to read into :help lspconfig, in the category of root directories. If you solve pls lemme know :^)

[@minhtam5661]

amazing video 👍 could you tell me about your pc specs? (is it macbook m1?)

[@chrisatmachine]

I'll never own a macbook again since they're just fancy spy devices at this point. I have a PC: ryzen 3600 and 2070 GPU for videos. And a s76 lemur which I do most of my development on.

[@breakersun]

thanks for such great video. just wondering where this handler.lua came from? I mean, what's the idea to create a handler.lua in the first place? is it a request needed by some plugins or something? just curious how it works. Sorry if this is a silly question. thanks.

[@jrdicoll]

I have the same doubt, I got so lost in this part of the course hahahah

[@cryptocurrents946]

BTW the "gl" key-binding now reports that: vim.lsp.diagnostic.show_line_diagnostics() is deprecated. The replacement in handlers.lua is: 'lua vim.diagnostic.open_float({ border = "rounded" })', See: h: deprecated

[@batteryonfire]

Hi Chris - Amazing. I spent the whole day in configuring neovim based on your playlist. Post full installation, the responsiveness on mac ( just 6 months only ) of NVIM is pretty poor. there is significant lag everywhere. I also restricted treesitter to only few languages and also the servers to just 4 or 5 but it didn't help much.

[@xGshikamaru]

16:15 : I always assumed M would represent a module

[@micahalan]

Thank you for your video and Neovim-from-scratch. 27:41 I noticed that Pyright wasn't able to resolve 3rd party modules/imports, I was also having the same issue, I was wondering if you knew how to fix this. Pyright seems to be working just fine in VSCode.

[@atuki-]

[@jamesstakebake3481]

I'll bet you M stands for module a generic name for a set of code. I know this is just speculation but it makes sense to me

[@ricardorien]

I'm using Nvim 5.0 == Error here == Error detected while processing /home/ricardo/.config/nvim/init.lua: E5113: Error while calling lua chunk: /home/ricardo/.config/nvim/lua/user/lsp/handlers.lua :36: attempt to index field 'diagnostic' (a nil value)

[@chrisatmachine]

Check the readme

[@FoolsTech]

The author of Lua is using M as abbreviation for Module all across his book Programming in Lua, especially in the chapter "The Basic Approach for Writing Modules in Lua". Though I don't recommend this book for getting started with Lua for Neovim, since it's covering Lua 5.3 which has some significant changes since 5.1 which is used in NeoVim's LuaJit. And it's also very academical and has a horrible editing and didactic approach, despite 4th edition. You're better off with Neovim's lua help pages. But once you figured out most important stuff in NeoVim and Lua it might be a valuable resource for advanced Lua programming.

[@duyhung.30]

can u make another vid using mason.nvim plss

[@cthutu]

You don't need cmp_nvim_lua now since the LSP manages it with the Lua server.

[@pythusiast4701]

I am using iTerm2 with Oh-my-zsh that is why somehow fonts are not working but unfortunately I am also not able to see the line diagnostics using {gl} shortkeys. I have cloned your repo and switching branches along with your videos but still I am not able to see suggestions cmp suggestions by LSP :( However I am trying my level best to keep up with you Also getting below error in NVIM: [nvim-cmp] documentation is deprecated.
