    Not particularly relevant to the core article, but just a dumb thought re: the LSP/LS annoyance mentioned in the intro.

    I think maybe some of it stems from 'ls' the command. If I saw something called py-ls instead of py-lsp, I may think it's a python based ls command. "Name Collision" as it were.

    Anyways off to read the rest of the article...

    As someone who recently set up something similar in Emacs with eglot I had to ditch Python-LSP-server.

    It was so incredibly slow to respond, even on a M2 Max MBP, that it lowered my productivity by orders of magnitudes (and made Emacs laggy).

    Maybe I did something wrong? I don’t know.

    What I do know is that I tried pyright instead as a different LSP-server for Python and I haven’t looked back.

    It’s a night and day difference. It’s snappy and everything works as expected, with venvs and mypy too.

      I agree. I really wanted to like python-lsp-server (aka pylsp), but I felt it's kind of a mess getting everything set up and configured. Loathe as I was to configure a server running in Node to help my editor with Python code, it's far and away the best option I've found so far.

      I do hope "ruff server" will do for Python LSPs what ruff did for linting and formatting.

        It's not ready yet, but https://pyrefly.org/ might be a good competitor/complement in the future

          Looks promising! It doesn't work with my poetry environment, but I like what I see so far. Definitely something to watch.

        I haven't tried the Ruff server yet, but Jedi Language Server is usably fast, and does a good enough job.

          Jedi's very nice for refactoring and auto-completion! I get more value from linting and type checking, though, and Jedi doesn't handle those. Pairing it with something like pyright is a great combination if your editor lets you connect to multiple servers.

      last time i looked the people were recommending basedpyright: https://github.com/DetachHead/basedpyright
