feat: support bazel (rules_python) as a PEP-517 backend #1103
Description
🚀 feature request
Probably very low priority, but having support for pyproject.toml would be awesome. Maybe for the first pass rules_python can support parsing [project] and other fields as metadata
Relevant Rules
py_wheel
Description
A clear and concise description of the problem or missing capability...Describe the solution you'd like
An example pyproject.toml:
[build-system]
requires = ["setuptools>=65", "setuptools_scm[toml]>=7", "wheel"]
build-backend = "setuptools.build_meta"
[project]
name = "my_project"
description = "description"
readme = { file = "README.md", content-type = "text/markdown" } # P1?
requires-python = ">=3.8"
version = "0.0.1"

]and its corresponding rule:
py_wheel(
name = "my_wheel",
pyproject_toml = "://pyproject.toml"
)Describe alternatives you've considered.
I can contribute the implementation upstream if this makes sense. I believe we already have tomli available so it should be relatively straightforward for implementation.

Any update on this?

Can you describe why this would be useful?
When a wheel is built and distributed (via PyPI or alternative artifact repositories) the pyproject.toml file is not leveraged by package installers.

https://peps.python.org/pep-0621/
The PEP describe the current generation of Python packaging system. A lot of these components help streamline Python project, and a lot of Python packages has adopted this (i.e numpy, scipy, pandas, and so on).
This makes it for a repo that setup pyproject.toml to set up adoption with bazel. We are evaluating bazel as build tool to make it consistent across our multiple projects.

I think I understand what you’re asking for. Are you asking for support of specifying the third-party dependencies of the project? Then the issue description isn’t clear.
The only table in PEP-621 that would be relevant for consumption via the rules would be the
dependenciestable. Possiblyrequires_python.The current mechanism for consuming third-party dependencies in the rules would be
pip_parseorcompile_pip_requirements.py_wheelis for building wheels.aarnphm commentedon Aug 27, 2023
Right, sorry for not making it clear. I think in terms of implementation rules_python will need to be able to parse
requires_pythonandbuild_systemin order to compile the wheel. Python specific build system such as hatch, flit, pdm has PEP517-compatible format designed for packaging.I believe the currently limitation for rules_python is that it depends on setuptools iirc. So in order to support pyproject, rules_python might need to add
buildto support parsing this pyproject.tomladditionally, all of the metadata can be used with distribution and wheel metadata generation.
I don't think this is specifically for parsing third-party dependencies.

Got it. So you want bazel to be usable as a PEP-517 compatible build backend?

I think @nicholasjng has created something of interest to address this ticket https://github.com/nicholasjng/bazelbuild
