Hi all, I have my third-party dependencies for a Python package specified in a

pyproject.toml

file, using Flit to build the sdist/wheel. Is there a way to set a

python_requirements

to read the

pyproject.toml

file, when I’m not using Poetry? I saw that Pants supports PEP 517 to build the distribution, but I’m curious if it can also single-source the external dependencies. Thanks!

Are the deps in pyproject.toml poetry-compatible? Or does flit do its own thing? If the former then a (possibly misnamed...)

poetry_requirements()

target should do the trick I think

It’s in a separate section

This is what the code looks like to do that https://github.com/pantsbuild/pants/blob/671cf3e09e0e3871c08cd01fea5be721a23b58f3/src/python/pants/backend/python/macros/poetry_requirements.py#L425-L543 Everything above in that file is the actual parsing code

Thanks! I’ll get something working and try to upstream it 😄

please feel free to ask for help! we definitely are eager to help out contributors 🙂 Check out https://www.pantsbuild.org/docs/contributor-overview for contribution guide, and https://www.pantsbuild.org/docs/plugins-overview for plugins in general I'm happy to write out more detailed instructions on how to do this if it would help

I think this tracks the idea: https://github.com/pantsbuild/pants/issues/16289

Ah awesome!
