[Pyobjc-dev] Newbie question : embedding pyobjc in a Cocoa app

[Byron W. <by...@bl...>]

I am building a cocoa app and would like to embed python to extend the 
functionality. Ideally I would like to created a python object and and 
give it a callback to my objective code.

Looking at the embedded Tutorial it seems that the way to embed pyobjc 
would be to create a bundle and instantiate that bundle to use the 
python modules within it. So I created a little test project and am 
somewhat stuck. I have the following main method :

int main(int argc, char *argv[])
{
	//NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
	//PythonGlue *glue = [[PythonGlue alloc] init];
	NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
     NSString *pluginPath = [[NSBundle mainBundle]
                                 pathForResource:@"Test"
                                          ofType:@"plugin"];
     NSBundle *pluginBundle = [NSBundle bundleWithPath:pluginPath];
     [pluginBundle load];
	NSLog(@"pluginBundle = %@",pluginBundle);
	Class testClass = [pluginBundle classNamed:@"Test"];
	NSLog(@"testClass = %@",testClass);
	id test = [[testClass alloc] init];
	NSLog(@"Terst = %@",test);
     [pool release];
     return NSApplicationMain(argc,  (const char **) argv);
}

I created a Test.py that contains the following :

import objc
from Foundation import *

class Test(NSObject):
	def init(self):
		self = super(Test, self).init()
		if self is None:
			return None
# subclass specific initialization here
# nib not loaded yet
		print "Test init()"
		return self

The bundle loads fine but the following statments return nil :
NSLog(@"testClass = %@",testClass);
NSLog(@"Terst = %@",test);


BTW, I am pretty new to Python, once I get over the embedding hurdle I 
plan to get deeper into Python. What am I doing wrong? How can I 
instantiate python objects via the bridge? Is what I am attempting 
possible (instantiating bundle and attempting to retrieve python 
class)? I looked around on the archive but all I could up with that was 
close to what I am attempting eludes to some old code that I can no 
longer find (PythonGlue.*).

Any help is much appreciated. BTW, I am looking at RubyCocoa as an 
alternative and their documentation seems to lack information related 
to embedding and extending a cocoa app :(
