Not sure how good it is.
How do you enable semantic highlighting for Python?
4 projects | /r/neovim | 7 Jul 2023

That explains why I didn't see textDocument/semanticTokens/full or anything like it in pyright's code. Do you happen to know of any Python LSP that has semantic tokens? pylsp, pyright, and jedi-language-server all don't have it. The only one I could find that might support it is https://github.com/mtshiba/pylyzer but I haven't tried that LSP yet

You might want to check Pylyzer then (https://github.com/mtshiba/pylyzer).
I'm not involved at all. It is still very very early in development. But as it is in the same vein, I thought I'd mentioned it here.
Python development in a restricted environment
1 project | /r/neovim | 28 Apr 2023

I don't need a lot. Something like "go to definition" and "show docstring" would go a long way, "signature help" would be nice... I'd take a nice completion, but that would just be a cherry on top. Any low-effort ways to achieve this? I've found https://github.com/mtshiba/pylyzer which looked really nice (and I could just download the right binary), but it has another programming language as a dependency, which is kind of intimidating...

Ruff v0.1.0
8 projects | news.ycombinator.com | 16 Oct 2023

I love Ruff. It's amazing. It's blindingly fast. I dig it.
But. v0.1.0 comes with a breaking change: the old `--output` option is now named `--output-format`, and it was only deprecated 3 weeks ago in version 0.0.291 (https://github.com/astral-sh/ruff/releases/tag/v0.0.291). That's bound to break some CI pipelines, and definitely breaks the python-lsp-ruff language server plugin. If you use the latter, I have a PR at https://github.com/python-lsp/python-lsp-ruff/pull/48 that will get you running again for now.
To be super clear, the Ruff team doesn't owe it to anyone to make the command line stable. This is a little inconvenient, but that's our problem, not theirs. They've made an amazing free tool we can all use. Still, it's something you'll need to know about and deal with.
