I'm working on my little project (an IM client) which I wanted to support plugins. My idea was that the core program would by itself do virtually nothing but manage plugins and all functionality would be provided by the plugins themselves (including protocol handling and UI. My first attempt was to check a directory for *.py files, execfile() them and rely on them to call a method to register a plugin object. This approach led to some conundrums and I discarded the it as bad design. My second take was to __import__() from each plugin file the plugin object and append it to a list of all plugins. But, this way I have to put imports into the __init__() of the plugin object or else they have no effect. Is this a valid approach? I'm starting to think that such problems are again symptoms of poor design.
I'd also be grateful for pointers to a well designed Pythonic plugin architecture but I'd much prefer a small project with a simple API. TIA, Greg Slodkowicz -- http://mail.python.org/mailman/listinfo/python-list
