Thanks for opening this, I really appreciate it.

[chrisgrieser]

btw, if you add a stylua.toml and/or .editorconfig, such formatting issues would be much easier to catch 🙏

I have a .luacheckrc at the root. Is stylua the more commonly used tool?

[icholy]

I just tested your fork and 0.9 doesn't seem to have vim.lsp.get_clients. I think we'll need to use vim.lsp.buf_get_clients instead. I can do that myself if you don't feel like it though, so let me know.

edit: I'll change the call after merging this.

Yes, by far. Among other things, the last luacheck commit was 6 years ago.

@chrisgrieser does the lua/neovim community have a convention for indentation?

[chrisgrieser]

@icholy not that I know of. I think every plugin author decides themselves, and sets that in their config file, I think. Adding an .editorconfig (supported by neovim core) is and a .stylua.toml as the most popular lua formatter should be enough from what I can tell.
