I don't know where/when this API bigotry started, but I wish it would
stop. Let's make Mac OS X great and stop bickering about whose API is
better than the other guys, or that the a particular problem is the
result of Carbon vs. Cocoa, and instead, let's just fix the problem.
This has nothing to do with Carbon - it has to do with how AppKit
dispatches odocs and how DropScript is written. From the DropScript
source:
- (BOOL) application: (NSApplication*) anApplication
openFile: (NSString* ) aFileName
{
if (myAppIsLaunching) myAppWasLaunchedWithDocument = YES;
[self runScriptWithFiles: [NSArray arrayWithObject: aFileName]];
return YES;
}
So for every file that you get a message for, you run the script. The
end result, that the script is invoked N times, shouldn't be surprising
to anyone.
I've fixed DropScript to do the right thing. I'm not a regular
contributor to Darwin so please tell me who/where to send the patch so
the problem will be fixed for users of the software.
