[Distutils] PBR/distutils2 with pep517 Support Was: Conditionless setup.py

[Chris Barker]

I've thought for ages that we could  transition to a more sane system by
convention:

"your setup.py, after being imported, will have a "setup_params" attribute
that is a dict that can be passed to setup()."

So tools that want metadata, etc. without actually running an install could
do;

import setup

name = setup.setup_params['name']
requirements = setup.setup_params['install_requires']

etc...

i.e -- it does need to run the code in setup.py, but it does NOT need to
run setup install, or build, or whatever else.


A typical simple setup.py with static meta-data would be:

from setuptools import setup

setup_params = {name:'sample',
                version:'1.2.0',
                description:'A sample Python project',
                url:'https://github.com/pypa/sampleproject',
                author:'The Python Packaging Authority',
                license:'MIT',
                packages:['the_package'],
                install_requires=['peppercorn'],
                ...
                }

setup(**setup_params)

But a setup.py could still have arbitrary code to build up the dict of
parameters if need be.
