This is what I do, from within my programm, and it works fine.

But I like to avoid this step.

-

I currently try to use the setuptools code to instantiate an egg from 
the setup.py file (which contains all information), and to apply then 
the functions from pkg_resources.

Looks somehow like this:


from distutils.core import run_setup
dist = run_setup( setuppys[0],None,'init')
print dist

loaded_components = []
module = []

import pkg_resources
for name in pkg_resources.get_entry_map(dist,'trac.plugins'):
    entry_point =
pkg_resources.get_entry_info(dist,trac.plugins', name)
	entry_point.load()

but this fails, I must have missed some point.

(('Expected string, Requirement, or Distribution', ))

although "dist" is an:

<setuptools.dist.Distribution instance at 0x0187E260>

-

How can I create an egg representing object (from the sources/setup.py), 
from which I can load the entry-points afterwards, without having to 
generate an egg_info on the file-system?
