efm-langserver VS dotfiles

Usually another program is used to lint/format code. Basic way is to just run them as a shell command or in another terminal and reload the file, but you can also hook it up to lsp. For example Javascript/Typescript projects use eslint and prettier. Runing `npx prettier` will format the files according to default rules. This is fine for every once in a while or a pre-commit hook. I think you are looking to have it integrated in nvim. Most formatters don't have a language server so you can connect them to nvim lsp with a general language server like: https://github.com/mattn/efm-langserver

I just started using helix and I absolutely love it 🔥 But I faced a really weird problem with using efm-langserver in helix.

I installed efm-langserver with Homebrew. Then, after my `mason_lspconfig` setup I tried adding this:

I've been using pint for formatting php files with null-ls.nvim. Few days ago null-ls.nvim has announced that the plugin will be archived in few months so I started migrating all my formatters and linter from null-ls to efm-langserver. I got other things such as prettier, black, isort, mypy, etc. working but can't get pint to work with php files: If I run pint via efm-langserver, everything is deleted from the buffer, and the saved file is formatted separately. How do I setup efm-langserver correctly to work with pint? Below is my config.yml for pint currently. yaml tools: pint: &pint format-command: "pint --no-interaction --quiet ${INPUT}" format-stdin: false languages: php: - <<: *pint Thank you.

It seems to be a recurring issue: https://github.com/mattn/efm-langserver/issues/181 https://github.com/mattn/efm-langserver/issues/241

I use the LSP if it supports formatting. I supplement that with efm-langserver which interfaces with CLI formatters and linters. It works well, similar to null-ls as I understand it.

As far as I know, the only solution (other than getting formatting directly from a LSP server) is to use EFM (https://github.com/mattn/efm-langserver), which implements the tricky logic of figuring out how to only update the changed text.

Thank you so much!! From my research it used to be documented in the wiki but was removed, and I was not using the option nesting within the completion key. Looking at your dot files made it clear how to use it, may help someone else:

I'm following along with this post and the associated dotfiles.

I call it with an autocommand on save here https://github.com/lukas-reineke/dotfiles/blob/master/vim/lua/lsp.lua#L124-L129

I have a format on save setup with efm that I'm pretty happy with https://github.com/lukas-reineke/dotfiles/blob/master/vim/lua/lsp.lua prettier is in there as well.
