[Pyobjc-dev] Detecting Python interpreters on startup

[Dinu G. <gh...@da...>]

Hi,

I got the following request, which makes me wonder how the one Python
interpreter is located running PyObjC applications?

In my bin-python-main.py (which might not be the newest one) I found the
following snippet:

     ## bin-python-main.py

     // figure out which python interpreter to use
     NSString *pythonBinPath = [[NSUserDefaults standardUserDefaults] 
stringForKey: @"PythonBinPath"];
     pythonBinPath = pythonBinPath ? pythonBinPath : @"/usr/bin/python";

Is this hardwiring /usr/bin/python as the one interpreter to use? Or
has this been determined at "project instantiation time" using the
Python-Cocoa Application template?

What is the general policy in chosing between possibly many installed
Python interpreters and/or can this decission be delayed until the
launch time of an application and how?

Thanks,

Dinu
