formatter.nvim VS lsp-format.nvim

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.

suffice it to say, I haven't needed to mess with it in a very long time, and it works very nicely and smoothly. I based it on https://github.com/lukas-reineke/lsp-format.nvim back before he extracted that plugin from his dotfiles, but over time I added a lot.

Ok guys I solved it by using this wonderful plugin https://github.com/lukas-reineke/lsp-format.nvim . Apparently it had something to do with setting up my autosave from null-ls but can't be sure. Anyways, solved.

My first reaction is to set a buffer-exclusive autocmd on lsp attach to call vim.lsp.buf.format(), that should work if you don't want depdenencies. Another way to go is https://github.com/lukas-reineke/lsp-format.nvim, it's a thin wrapper around nvim's format and can provide format on save.

Use lsp-format.nvim and put null-ls on the blacklist.

If you already use metals as a language server, it looks like scalafmt support is already built in. If you're using metals in Neovim but not getting formatting, check your lsp configuration. Alternatively, use lsp-format.nvim to ensure formatting happens. That goes for using it with null-ls, too.

Thanks! One additional question, I'm using lsp-format. And to use it, I just

My plugin lukas-reineke/lsp-format.nvim does that. It wraps around the built-in LSP formatting with a couple opinionated improvements.

You can take a look at my plugin LSP-format.nvim for a bit more robust solution to async format on save. But it will also write the file twice. There is currently no other way to do this.

I recommend instead using lsp-format.nvim to manage multiple LSP clients trying to format.
