This page concerns the development for new PyMOL Plugin Architecture. We are requesting ideas, code, etc on how to best implement a successful plug in system.
Review of Current Plugin System
Ideas/Features for the New Plugin System
More than one file per plugin
I'd like plugins that behave like proper Python modules with the ability to span multiple files/directories. One simple way to do this would be to distribute plugins as zip files. E.g. if we have a directory Foo that contains
MyMod __init__.py """Some documentation here""" Foo.py def doit(): print "It is done!"
We can zip it up like
If you stick MyMod.zip in a plugins directory like /blahblah/Pymol/plugins/MyMod.zip you can then say this: <source lang="Python"> sys.path.append('/blahblah/Pymol/plugins/MyMod.zip') from MyMod import Foo Foo.doit()
Python does not impose the restriction that the module/directory name (MyMod) should be the same as the zip file name (MyMod.zip), but we might want to.
Then we need to formally spell out the API by which the Plugin is launched.
This makes it very easy to install/uninstall plugins, and PyMOL can just have a simple loop that iterates over the plugins directory, adds the appropriate things to sys.path, verifies that the resulting objects support the API, and adds them to the menu.
Some sort of persistent config files where users can store things like paths to relevant files, settings, etc. would be very useful. The APBS plugin, for instance, is a bit of a bother to use when you have APBS installed in a non-standard location. It would be very convenient if you could set the location once and have it persist.
