[Pyobjc-dev] Calling python from objc

[Akhar <ak...@gm...>]

I seem to have a bit of a problem with calling python objects from 
cocoa apps. I did find your post on soureforge about how it could be 
done (http://sourceforge.net/mailarchive/message.php?msg_id=7503787).  
I tried to do as the poster did however I need to call the python code 
from another object that is linked to a custom view. Here is what I 
have :
-----main.m
#import <Cocoa/Cocoa.h>
#import <PythonGlue.h>
#import <Script.h>
int main(int argc, const char *argv[])
{
     return NSApplicationMain(argc, argv);
}

-----myoutput.h,
/* outputView */

#import <Cocoa/Cocoa.h>
#import <PythonGlue.h>
#import <Script.h>
@interface outputView : NSView
{
	NSString *command;
	NSColor *bgColor;
	NSMutableDictionary *attributes;
	Script *script;
}
- (void)prepareAttributes;
- (void)drawStringCenteredIn: (NSRect)bounds;
- (void)setBgColor:(NSColor *)c;
- (NSColor *)bgColor;
- (void)setString: (NSString *)cmd;
- (NSString *)command;
@end

----myoutput.m,
#import "outputView.h"

@implementation outputView

- (id)initWithFrame:(NSRect)rect
{
	if (self = [super initWithFrame:rect]) {
	[[PythonGlue alloc] init];
	scr = [Script instantiateSubclassNamed:@"pyScript"]; // this is where 
it should run the python code
	NSLog(@"initializing view the big one");
	[self prepareAttributes];
	[self setBgColor:[NSColor yellowColor]];
	[self setString:@"Nothing to see here! move on!"];
	}
	return self;
}
... more ... but ... cut ...
@end
----Script.h,
/* Shell */

#import <Cocoa/Cocoa.h>

@interface Script : NSObject
+ instatiateSubclassNamed: (NSString *) aClassName;
@end
@interface Script (pyScript)
- (void) test;
@end

----Script.m,
#import "Script.h"

@implementation Script(pyScript)
+ instantiateSubclassNamed:(NSString*) aClassName
{
	Class aClass = NSClassFromString(aClassName);
	return [[aClass alloc] init];
}

@end

----pyScript.py
from objc import *
from Foundation import *
from AppKit import *

Script = lookUpClass("Scipt")
class pyScript(Script):
     def init(self):
         print "creating object"
         return self
     def test_(self, obj):
		print "in python here test worked"

and the pythonglue.h/.m and the python framework.
 From that standpoint all seems great. I have the exact same setup as he 
does except for the main.m that was left as is. instead in myoutput.h I 
created the Script *py; variable to my knowledge this is not the 
problem, I get a:
  objc.nosuchclass_error: 'Script' is not defined. error.
What am i doing wrong?
