Ok, nice to hear that.
Setting up the right environment for plugins is also very hard, if not impossible to do completely correct: cpython just isn't designed for having several completely seperate interpreters in one application (and no, Py_NewInterpreter/Py_EndInterpreter don't count). Different plugin bundles with py2app will share part of the environment, such as having a shared sys.path.So does that mean that I shouldn't run two Python plugins in the same program, or that I need to be careful that they have the same dependencies, or that the first contains all the dependencies of subsequent plugins, or what? I'm just trying to understand here.
If you have two python plugins for the same program they should at the very least use the same version of python, using different versions of python may or may not work.
I'd have to study the plugin main code to be absolutely sure, but AFAIK if plugins A and B both depend on package C they should depend on the same version of C because at runtime they will both use the version that's included in whichever of the plugins was loaded first.
If you can arrange for one of the plugins to be loaded first it would be useful to have that plugin include the Python framework and large extensions (like PyObjC). That way other plugins can stay very small and you don't get confusion on what gets loaded.
