Setuptools zig build

A setuptools extension, for building cpython extensions with zig build, enabling simple source-only pip distributions that compile at install time. This is my take on deinventing the wheel

check out zig-zon for a full example.

Example

Your project needs to have:

• setup.py to configure this setuptools extension to run during python's wheel build
• build.zig to configure the build of the shared library
• build.zig.zon optionally - to specify zig dependencies

from setuptools import Extension
from setuptools import setup

setup(
    name='zig-zon',
    packages=[],
    zig_build={
        # stores zig's depdendency pacakges in python's sdist. This requires a call to
        # CPython.addSdistList(b); in `build.zig`
        # If set to False, potential dependencies will be downloaded by zig instead.
        "sdist": True,
        # tries to import 'ziglang' to get a zig compiler when building wheel
        "use_ziglang_python_package": True,
        # passes -Doptimize= to zig build
        "optimize": "ReleaseSmall",
        # passes -Dversion=<pip package version> to zig build
        "pass_version_option": True,
        # extra arguments to zig build. In this case we pass the `install` and `test` steps
        'extra_args': [
            "install", "test",
        ],
    },
    # Names of the libraries your `build.zig` will produce, and this module will install
    ext_modules=[Extension('zig_zon', [])],
)
