What is the correct way to share package version with setup.py and the package?

Question

With distutils, setuptools, etc. a package version is specified in setup.py:

# file: setup.py
...
setup(
name=\'foobar         


        

Answer 1

The accepted answer requires that the package has been installed. In my case, I needed to extract the installation params (including __version__) from the source setup.py. I found a direct and simple solution while looking through the tests of the setuptools package. Looking for more info on the _setup_stop_after attribute lead me to an old mailing list post which mentioned distutils.core.run_setup, which lead me to the actual docs needed. After all that, here's the simple solution:

file setup.py:

from setuptools import setup

setup(name='funniest',
      version='0.1',
      description='The funniest joke in the world',
      url='http://github.com/storborg/funniest',
      author='Flying Circus',
      author_email='flyingcircus@example.com',
      license='MIT',
      packages=['funniest'],
      zip_safe=False)

file extract.py:

from distutils.core import run_setup
dist = run_setup('./setup.py', stop_after='init')
dist.get_version()
