It's way more painful to extract the first matching group like this without ripgrep, afaict

I would honestly be fine hard-coding this and the latest version, since we already search-and-replace the latest version every time we upgrade the LSP. Fewer dependencies, easier to maintain (IMO). But of course I defer to you.

sed -rn 's/.*"ruff>=(.*).*",/\1/p' pyproject.toml works

Maybe it's just me but a sed invocation like that is entirely incomprehensible haha :)

I'd like to try this out since I wrote it up and haven't tried generating matrix test versions like this before, but at the first sign of trouble I'm happy to just switch to hard-coded versions.

It seemed overkill to include these in the matrix — it was a lot of testing

To me, lowest and highest python versions would be sufficient in general

I wish we could just store "fixtures by version" or something, rather than having to construct these and encode facts like "Which URL is present at which version?" in the test logic. Like, in Rust, we'd just run the command with different versions and snapshot the output, which feels easier to maintain and understand. I don't know if I have a concrete suggestion here -- more reacting to the increased logic in the tests now.

Hm interesting yeah.. this whole bit would make more sense as a snapshot too.

A strong case for us building Python test tooling <3
