formatter.nvim VS nvim-lspinstall

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.

A word of caution, I believe lspinstall has been deprecated in favor of nvim-lspinstall which itself has also been deprecated in favor of mason-lspconfig

kabouzeid/nvim-lspinstall will aide in installing lsp's if you want. I have chosen not to because I want to have my full setup scripted so when I setup any new machine I just run my ansible-playbook. This library is nice to just set things up quick and play with them.

nvim-lspinstall

I'm trying to edit a lua file, and got this error which I realize is because I didn't have the Lua language server installed. So using the LspInstall plugin, I did :LspInstall lua which was successful.

Once you have it installed, you can configure it following the configuration of this file: https://github.com/kabouzeid/nvim-lspinstall/wiki. The part that ia bellow the comment "-- lsp-install" works and it was what I used initially when I didn't really know much about configuring neovim.

I am using lspinstall to install language server. It uses this json-language-server. As the docs says jsonc is supported and it allows comments in jsonc filetypes but the lsp is not showing diagnostic if I make any other syntax error. On line 34 i have removed a comma and still lsp showing no diagnostic error in jsonc file.

You could try to use the instructions that nvim-lspinstall uses to install the tailwindcss language server: https://github.com/kabouzeid/nvim-lspinstall/blob/main/lua/lspinstall/servers/tailwindcss.lua (lines 4 - 12)
