Do you have any idea for auto-completion feature of ruff-lsp?

I want to use auto-completion with ruff-lsp.
I'm trying to implement this feature while watching python-lsp-server implementaions. python-lsp-server uses jedi for auto-completion.

It works now but sometimes very slow compared to vscode IntelliSense (pylance) (My editor is helix-editor).

Specifically for helix, multiple LSP support may also fulfil this need: helix-editor/helix#2507
Although, that would inherit the overhead of python-lsp-server.

[tsugumi-sys]

Yes, and that also would be because of jedi performance.
davidhalter/jedi#1059

I wish there is a rust implementation of jedi.

Presumming you off load linting jobs to ruff. Then for autocompletion, you may use pyright, which is much faster than python-lsp-server.

I guess my comment belongs on this topic - I am using neovim with coq. My previous other Python LSP tools provided auto-completion with coq. Those are pyre, pyright and python-lsp-server. ruff-lsp does not integrate with coq out of the box. I'm happy to make some effort to do the integration but have no idea where to start.

This server handles linting (at least currently). Why would you expect it to also handle code intelligence including completions? You can always use additional servers for that.

I agree with you.
I'm helix user and I did not know about multiple LSP settings, but I just found this PR .

And I added auto-completion with jedi to ruff-lsp in my forked repo, but now I think it's not a good way for the reasons above.

@rchl oh, OK. I guess it's because I stumbled across ruff-lsp via Mason and it's categorised as the same type of tool as the old ones I was using (i.e. LSP), which all plug in to coq and trigger the LSP completions. So I assumed ruff-lsp not only did linting but also some value-adds such as LSP hints to coq. Thanks for the correction.
