Hi All,
Given a distribution name (ie: one of those things setuptools uses,
'name' parameter to setup.py's setup call, etc) of a dsitrbution
that has been installed with easy_install, buildout, pip, etc, how
can I find out what python packages (ie: dotted names that I can
import) are provided by that package?
I'm trying to write a scanner than looks for SQLAlchemy table
objects and it would be great to be able to pass a distribution name
rather than a set of dotted package names...
get_distribution('projectname').get_metadata('top_level.txt').splitlines()
will return you a list of top-level package or module names provided
by the package.
Subpackages you'll have to find yourself; the pkgutil module in 2.5+
has a walk_packages() that might be helpful.
(Note that if there are packages installed in "flat" form (e.g.
pip-installed or system-installed), you may see overlapping packages
in the same directory, so simply walking packages in a distribution
object's base directory may include packages and modules from another project.)
