Sorry, I didn't specify enough constraints in my original post.
- The code that calls the external scripts has to be cross-platform, and run on
linux as well as OS X. So, no NSTask.
- I can modify the code that calls the scripts, and I can use OS X-only APIs to
set up a global environment (for processes launched by my app) if that sort of
thing is possible.
- I don't want to make the user modify things like launchd config or /etc. They
can install required dependencies (like certain Python modules), but that's
about it. I'd love to find a way to package those in the app bundle, too.
I'm thinking the best thing to do is pass in paths and an environment string to
be used in the system() call (e.g., invoke it as "export PYTHONPATH=...; export
PYTHONHOME=...; path/to/script args"). Maybe I can even leverage that to let me
put the requisite python modules in the app bundle...
