Install dependency groups in the `uv pip` interface, i.e., `uv pip install --group`

[hynek]

Hi,

I got really excited about PEP 735 but then I noticed it can't really be used with unlocked packages?

Like in hynek/svcs#107, I would like to be able to do uv pip install --group dev --editable . (instead of uv pip install -e .[dev] although if you just allowed to pass dep groups like this, I'd be happy too)

This is completely orthogonal that many open-source packages can't use locking yet due to #7533 – some/many people just don't want to go that route.

Or am I missing something?

We didn't add it to the uv pip API because it's not available there yet and we want to match their interface

Ah cool, that was my suspicion!

🙏 patiently awaiting this 🙏

In the meantime, I'm using

uv export --only-group=... | uv pip install --requirements=-

to install specific dependency groups.
