For example, zc.catalog declares these dependencies in its setup.py

Is it possible to reliably get this list in a custom Python code
without having to parse setup.py?
Something like this should do the trick:
import tempfile, os.path
from setuptools.sandbox import run_setup
def get_requires(setup_dir, empty_tmpdir):
tmpdir = tempfile.mkdtemp(prefix="egginfotmp-")
run_setup(os.path.join(setup_dir,'setup.py'), ['-e', tmpdir])
for dist in pkg_resources.find_distributions(tmpdir, True):
return dist.requires()
else:
raise RuntimeError("egg_info didn't work")
You'll get back a list of pkg_resources.Requirement objects rather
than strings, but you can turn them back into strings if you like.
