[@Pau1danelli]

Thank you so much for this series. I had some time over christmas and after watching these videos was able to translate my vimrc setup to be totally Lua.

[@user-yn6ii7ys3u]

Your playlists are the best neovim related content on youtube rn. Thank you very much for making these.

[@pmerikan]

What can I say? Chris, you're the best!! 6 months ago I started migrating my vim config to Lua and also migrated to Lsp, but I never really landed it. I have picked some settings here and there but didn't always understand what it actually did. I have been following you for quite some time now and I must say that you are the only one that actually explains it to us mere mortals. Keep up the good work.

[@h4pz]

Thanks Chris for the great content. Always appreciated

[@smjonas8616]

Super useful, thank you! I've been trying to wrap my head around null-ls for quite some time. Now I finally understood it!

[@exequiellaresdev]

Thank you! I love this series. I'm finally could get my neovim php environment working 💪

[@318307able]

Just simply the best. Thank you Chris

[@nodidog]

Thanks Chris, series has been very helpful

[@Chris-jp6ll]

A second before throwing the towel your series comes along and saves the day. Thank you :)

[@srinivasrg5125]

Thank you Chris. Great help for me!

[@LongestYardstick]

Dude I’ve been playing with lunar vim all day and you’re a Lua coding monster! Really enjoying your code, thanks for everything.

[@luskira]

Thanks so much you've lift such a weight from my shoulders by compiling this playlist

[@ekekw930]

Thanks Chris

[@MartinsTalbergs]

this vid will make numbers!

[@ytcdi]

I am using it! Thanks

[@josemiguelochoa5372]

Nice content. Thanks!

[@LudoTechWorld]

I'm successfully using this plugin, but it works because I copied configurations I found here and there, I didn't really understand how it works... until now! Thank you!

[@tobias-edwards]

Thanks for this! The null-ls documentation is so verbose and hyperlinked. It's like navigating a digital Yellow pages

[@tobias-edwards]

If null-ls is to bridge the gap between Neovim's native LSP and formatters, linters, etc. I see that the native LSP is slowly providing support for linters like 'eslint'. Would this mean that in time null-ls will be redundant?

[@andresgutgon]

Thanks a lot for these series. Is super good! I have a question, what about doing formating when saving the file?

[@Heshamelfakharani]

thank you for all this. can you make an extra video for DAP or debugging in general?

[@namtruong4071]

How can i setup prettier format on save base on local .prettierrc like vscode in null-ls

[@blumaa]

Hey man if you're ever in Berlin, let me know- I'll buy you a beer or two. Thanks for these tutorials!

[@tridibbiswas3361]

Hi, Thank you for this video. I am using flake8 for diagnostics with null_ls. While its working properly I am getting two sets of same kind od diagnostics one from flake8 configured through null-ls and the other one through pyright which I am using as my lsp server. How to stop the diagnostics from pyright only and use the one from flake8

[@IranzinhoBRG]

Is there a way to make .prettierrc options take precedence over "extra_args"? Great video, congrats!

[@KronosaurusRex]

Maybe this question is somewhat dumb, but is there a way of having that global prettier settings and adjusting so it respects the prettierrc or similar?

[@flywithoutwingss]

Hi, Ive been reading the documentation, but I cant figure out, how to configure options in prettier, like for example "--print-width 110", this value I cant use it as an extra argument, Dont know how to add arguments that need a name and a respective value. Anyone having this issue ? thanks.

[@Oswee]

Any idea how null-ls is different from efm-language-server? And can it chain multiple linters and formatters for a single buffer?

[@atahanozbayram1619]

Is there any plugin that helps with updating imports and paths when a filename is changed?

[@WeAreTeamNovus]

How can I do formatting when writing to a file (:w)?

[@willianalmeida3670]

Can anyone show me a way to configure Lvim to develop in React. I couldn't configure auto complete for html tags (with auto closing) inside jsx/tsx..

[@MohdAfnan]

Hey Chris can you make a video on cheovim which is made by NTBBloodbath

[@ebiscaia]

Hi Chris, When I try to format a lua file using :lua vim.lsp.buf.formatting_sync() it prompts me which formatter to use (summenko [lsp] or null-ls). Is there a way to choose the default one? Thanks

[@ebiscaia]

Nevermind, it was just a matter of seeing the rest of the video. Cheers, mate

[@barefeg]

@@ebiscaia What was the solution? he fixed it for tsserver but not lua

[@ebiscaia]

@@barefeg apply the same idea just change names

Hi Chris, thank you for the series. Im following one-by-one and finally decided to take the jump and ove over to the Lua side. Im facing a big speed issue on startup though. Im running macOS Catalina on a MBP 2019 16" (Intel) and nvim --startuptime takes about 400+ ms on every startup. Your startup speed seems much faster, could you run a benchmark and share your numbers?

[@MartinsTalbergs]

Oh no, that is long startup, see the output of :scriptnames - a list of loaded junk, maybe something you do not need

[@julien4699]

@@MartinsTalbergs I have already tried to disable default plugins in my lua config. Not sure what else could be done... Full disk encryption is enabled on my laptop, perhaps it slows it down some. But judging by Chris' videos the startup is almost instant

[@MartinsTalbergs]

@@julien4699 It might be that one of plugins has a bug - I had an issue due to bug in nvim-tree, if Git-icons were enabled, it took 400ms on every file write, due to doing some I/O stuff. Maybe it is deeper - if you happen to use apples M1 chip it has to carry out virtualization for another architecture, since the new one is not widely supported yet. You already mentioned the "nvim --startuptime", see the step that has the longest exec time there. Encryption should not be the issue.

[@julien4699]

@@MartinsTalbergs Im running a "nvim --startuptime" for each branch as I go. LSP + cmp seems to add a bit of overhead. But nothing stands out that much to me. What surprises me is how quickly the startup slows down when adding a few more plugins (cloning a later branch in the series) while I read of people with 40+ plugins getting startup times under 100ms My machine is Intel-based FWIW

[@rounakjain5774]

Thanks for all the good work! However, I just lost an hour because I used your config and had not watched this video. The team at my workplace prefers double quotes. I was trying all sorts of things in my `.eslintrc` and `.prettierrc` but could not stop nvim from changing double quotes to single quotes. So, I guess its not really a good idea to keep the `--single-quote` preference in `null-ls.lua`

[@zen-ventzi-marinov]

Does you .pretterrc just work out of the box? If it does work, would you mind a quick test with .prettierignore(e.g. add a *.ts or some other file) and see if it works?

[@aaronyx2124]

in case anyone ran :lua vim.lsp.buf.formatting_sync() and got an error, change it to :lua vim.lsp.buf.format() and you should be fine

[@nex7268]

what broswer r u using, that theme looks extreamly cool :D

[@chuny_dev]

In html appears the prompt :C

[@TheZusak]

Can you instead use Mason to install the formatters and use null-ls to apply formatting?

[@br3ntor]

That's what I did and worked for me.

[@wayneswildworld]

How do you install the binary for black?

[@chrisatmachine]

using mason now, could also use a package manager

[@wayneswildworld]

​@@chrisatmachine Firstly thank you for responding. I've gotten everything working with no errors however I can't seem to figure out how to get prettier to work I can't run the vim formating command that you use in this video. The other thing I am struggling to figure out is how to do find and replace in vim. If you can help me with these issues I would really appreciate it. I made an issue on git hub wakywayne

[@helloquico]

'brew install stylua' on a mac

[@cthutu]

I prefer to add "vim.cmd [[autocmd BufWritePre * lua vim.lsp.buf.formatting_sync()]]" to my init script to do formatting everytime I save a file.
