Development Dependency Overrides

[iloveitaly]

One of the things I've always missed from ruby is development dependency overrides. Here's the situation:

• You have a dependency in one of your projects that is published on pypi
• Something is broken in it. You clone it with hopes of fixing it locally before getting the patch merged upstream.
• You want to temporarily override the pypi reference to point to a path on your local filesystem without modifying pyproject.toml

Ruby allows you to do this with:

bundle config set local.rack ~/Work/git/rack

It would be great if uv provided similar sort of functionality.

I believe this is possible today with:

[tool.uv]
override-dependencies = ["dependency @ file:///path/to/dependency"]

I think you can also run code with the --with option of uv run command, or --with-requirements if you have many. That won't modify the pyproject.toml and the code will only run in an ephemeral virtual environment.

This is awesome. Will try this out and report back. Thanks for all of the help.
