Let uv provide python versions #72

Closed bluss closed 1 month ago

bluss commented 1 month ago

What's the problem this feature will solve?

Hi, do you plan to let Uv supply python installations? It could install all necessary versions. Similar to the experiment I did with rye ( https://github.com/bluss/tox-rye ).

It removes the need for python installs to be arranged up front. Or enables already installed but not previously discovered (by tox) python versions installed by uv.

Describe the solution you'd like

tox-uv would request (and if needed install) each python version from Uv. Uv has a preview feature for installing python (uv python).

Alternative Solutions

Possibly do it with another tox extension that complements tox-uv instead of replacing it? I'm not up to date on tox's plans for python discovery, maybe there's another way to hook into it.

Additional context

Uv python toolchain docs https://docs.astral.sh/uv/concepts/python-versions/ (NOTE: preview docs for preview features)

Well ok, my bad, that's what it's already doing, great.

This doesn't seem to work for python versions that uv could provide but that don't already exist on the system, tox skips them, or if skip_missing_interpreters is false tox fails with "No interpreter found for Python X.Y in managed installations or system path"
