Python packages without setup.py

[Adam <adam%netbsd.org@localhost>]

Some recent Python packages do not distribute setup.py, but rely on other tools to build and package.

Here are the steps I've taken to generate setup.py for PkgSrc using devel/py-flit.


cd ${WRKSRC}
flit-3.10 build --format sdist --setup-py
bsdtar --strip-components 1 -zxvf dist/*.tar.gz '*/setup.py'
sed -i '' -e '/generated by flit/d' -e 's,distutils.core,setuptools,' setup.py


Copy setup.py to ${FILESDIR}/setup.py


Add these to Makefile:

# Important: Re-generate files/setup.py on update.

pre-configure:
	${CP} ${FILESDIR}/setup.py ${WRKSRC}/


I used this method on py-flit_core, py-flit, py-tomli, and py-tomli_w.

I know it's a little bit messy and only applies to packages using Flit as a tool in pyproject.toml.

Kind regards,
Adam
