[Distutils] Finding modules in an egg / distribution
Hi there, We have been struggling to find a nice way to list all the modules (or packages) that are part of a particular Distribution (or egg). Nice should also mean that it works when the egg is installed. We have a need to do some introspection on the code shipped as an egg. Any ideas?

Trouble is that pkgutil.walk_packages needs a path to search from. Distribution.location is always your site-packages directory once a Distribution is installed, so walking that just gives ALL installed packages. If your Distribution contains some sort of main package that contains everything in it, you can use that package's .__path__, but then you'd need to discover what that package is. Distributions could also contain more than one package next to each other, and top-level modules. (The __path__ of a top-level module is also simply the site-packages directory.) There is a metadata file top_level.txt which one could use to get the names of top-level packages/modules in the Distribution. This can however contain a namespace package too - and you don't want all the packages inside the namespace package - just the bits inside the chosen Distribution...

Hello Iwan, This project can answer your questions: https://pypi.python.org/pypi/pkginfo FTR we planned to include something like it when the distutils2 project was active; distlib or the variant of distlib that will end up in the 3.4 standard library could include similar features.

Ah, well in that case you'll have to inspect either .egg-info/SOURCES.txt or the PEP 376 installation manifest. I don't know of any reliable way to do what you want for system-installed packages at the moment. ___ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
