Organize a python library as plugins

Question

I would like to create a library, say foolib, but to keep different subpackages separated, so to have barmodule, bazmodule, all under the same foolib main package. In other words, I want the client code to be able to do

import foolib.barmodule import foolib.bazmodule

but to distribute barmodule and bazmodule as two independent entities. Replace module with package as well... ba[rz]module can be a fukll fledged library with complex content.

The reason behind this choice is manifold:

I would like a user to install only barmodule if he needs so.
I would like to keep the modules relatively independent and lightweight.
but I would like to keep them under a common namespace.

jQuery has a similar structure with the plugins.

Is it feasible in python with the standard setuptools and install procedure ?

You may be looking for namespace packages. See also PEP 382.

Yes, simply create a foolib directory, add an __init__.py to it, and make each sub-module a .py file.

/foolib barmodule.py bazmodule.py

then you can import them like so:

from foolib import barmodule barmodule.some_function()

Yes, this I know. My problem is not how to create a package containing two modules. My problem is to distribute them as two independent "sublibraries" part of the same library namespace.

Why not simply have a /plugins/ folder that users can drop plugins into and that gets checked when foolib is called?
