Setup.py util to get common description variables like version, author, etc from packages without importing the modules. (To avoid circular imports and related errors)

setup_utils.py

__version__ = "0.1"
__author__ = "mariocesar"

def get_module_meta(module_path):
    import re

    with open(module_path) as cakebet_meta:
        meta = cakebet_meta.read()
    return dict(re.findall('(?P<key>__.+__)\s=\s["\' ](?P<value>.+)["\' ]', meta))

test.py

from utils import setup_utils

meta = setup_utils.get_module_meta('setup_utils.py')

assert '__version__' in meta
assert '__author__' in meta

assert meta['__author__'] == 'mariocesar'
assert meta['__version__'] == '0.1'
