Hi,
I'm wondering if someone has a nice solution for the following problem.
I'd like to be able to import all the modules in a directory, such that
developers can simply add a *.py file somewhere (or a directory), and
let the framework import them automatically for doing something with
them.
For example, let's take the following directory structure:
framework
core.py
/ modules
/ __init__.py
/ module1.py
/ module2.py
/ module3
/ __init__.py
So we can end up with something like that pseudo code in the
modules/__init__.py:
__all__ = [module_path for dir_path in
os.listdir(os.path.abspath(__file__))
if module_path.endswith('.py')
or (os.path.isdir(module_path)
and os.path.exists(os.path.join(module_path, "__init__.py")))
]
The framework is then be able to use:
import modules
for module_path in modules.__all__:
the_module = __import__(module_path, fromlist=[''])
## Do additional checks and process ...
[As a side note, i never really understood the fromlist argument, maybe
it's worth another thread?]
This solution works but has at least 2 flaws:
- won't work with eggs or zip files out of the box
- is not pythonic (not sure it'll even pass python 3)
Any suggestion?
Philippe
