uv

I've slowly been getting more familiar with uv and the broader new school of python packaging ecosystems (sorry, I used virtualenv for a long time, it does the job fine), and one of the most exciting things to me is its use of dependency groups in a pyproject.toml file: finally, a non-janky way to use different packages in different environments. However, I think its documentation leaves a bit to be desired on this front, so I wrote down a few commands I find myself using regularly.

To add a package to a specific group:

uv add --group dev python-dotenv
