Consider using ruff-lsp instead of pylsp as the default language server for Python

It's my view that ruff-lsp can provide a nicer user experience than pylsp mostly because ruff is very fast (written in Rust), so why not switch to it by default? Configuration for Helix is avai... More on github.com

r/neovim on Reddit: Ruff v0.4.5: Ruff's language server is now in beta!

May 23, 2024 -

Ruff Server is now in beta! In case you didn't know, ruff server is an lsp for python that is also a rewrite of ruff-lsp in rust which was originally written in python I believe. What excites me the most about their blog post regarding the new release is the last bullet point...

Supporting more general language server features: We plan to expand the server's capabilities beyond linting, formatting, and diagnostics.

I hope this means that we might see a highly performant, high quality alternative to the other python lsps.
