Description
Hi! My name is Alek, and I am interested in using this Buildpack in a tool to create both Development and Production images of an application.
I did a little digging through the codebase (I don't know Rust, so I relied pretty heavily on Claude), and it seems I'm not currently able to override which set of dependencies the Buildpack pulls in (I.E. something like modifying the pip install -r requirements.txt command to pip install -r dev-requirements.txt or modifying the uv sync command to uv sync --group dev).
Would it be possible to add one or more configuration options to this Buildpack to support this feature?
Possible Implementation
If I understand the Buildpack Specification correctly, this could be done through one or more environment variables of the form BP_*.
Would something like this make sense:
BP_PIP_REQUIREMENTS=<file with your requiremnens>
BP_UV_GROUP=<your uv group>
I believe if BP_PIP_REQUIREMENTS was set, then you would need to detect that file to pass detection. If BP_UV_GROUP was set, you would fail detection if uv.lock was missing.
I am unfamiliar with poetry, so I'm unsure what the appropriate mechanism for that tool would be.
PS Hi @edmorley! It was a pleasure meeting you at PyCon!
