mason-null-ls.nvim VS formatter.nvim

I followed the default configuration with Lazy.nvim I found of the github page of mason-null-ls : https://github.com/jay-babu/mason-null-ls.nvim

I will update mason-null-ls: https://github.com/jay-babu/mason-null-ls.nvim#available-null-ls-sources. It is inaccurate since this commit. As long as the convention is followed (aka something-like in mason and something_like in null-ls) exceptions aren't needed. Exceptions live here: https://github.com/jay-babu/mason-null-ls.nvim/blob/main/lua/mason-null-ls/mappings/source.lua

You can use mason-null-ls.nvim also, is a similar bridge to the mason-lspconfig plugin. The plugin translates the server names between mason and null-ls so u just have to add the servers you want to use.

Personally I don’t use linters inside of the editor itself, but I do use formatters. For that I use null-ls which also works for linters, and allows you to configure them (eg. pass arguments to the binary) and hooks them as regular language servers, so you could look into that. The formatters can also be installed through mason but there’s also this plugin which says it’s a bridge to use mason and null-ls (I haven’t tried it, for me things just work with mason and null-ls).

Let me know your thoughts on https://github.com/jayp0521/mason-null-ls.nvim :), just updated the docs. Note: this plugin doesn't do any extra setup outside what is requested.

Can anyone explain why someone would use null-ls if you're using the modern lsp setup (say, from kickstart.nvim). I see comments mentioning formatting. I see formatters mentioned several times. Why not just use https://github.com/mhartington/formatter.nvim?

I use null-ls (https://github.com/jose-elias-alvarez/null-ls.nvim), I haven't tried it for python, but haven't had trouble with lua, js, ts or rust. You can also look into formatter.nvim (https://github.com/mhartington/formatter.nvim).

I use formatter.nvim for formatting

For formatting, formatter.nvim is a good choice and has similar setup to nvim-lint.

I finally installed this formatter plugin and configured it to execute de clang-format command like this

mhartington/formatter.nvim is used for automatic code formatting. Its configuration also shows how to use nvim_create_augroup and nvim_create_autocmd from Lua.

This might have something to do with extmarks being clobbered when the new text is written. For example, here is a GitHub issue describing the problem: https://github.com/mhartington/formatter.nvim/issues/22 This is for formatter.nvim, but this would likely apply to any process that rewrites the whole buffer.

i have always had trouble with lsp formatting and null-ls (may just be me, i'm not super clued in) so i use formatter.nvim https://github.com/mhartington/formatter.nvim/

Take a look at formatter.nvim

I've had really good experience with formatter-nvim.
