[Pyobjc-dev] char return values

[Ryan B. <ry...@wa...>]

Hey,
	I'm building a bridge between Supercollider (an interpreted, audio  
oriented programming language) and Objective-C/Cooca, and I've been  
looking at the pyobjc source code a lot to see how you are doing  
things. The pyobjc source has been a huge help, and I'm constantly  
impressed by it's cleverness. I'm going to be directly ripping off  
the gen_all_protocols.py and gen_protocols.py scripts to generate  
lists of informal protocol method type codes.
	One of things I noticed in looking at the code is that the  
pythonify_c_value function (in objc_support.m) assumes that all  
char's should be passed to python as ints. The comment says this is  
because BOOL's are typedefed to char. While BOOLs are used a lot more  
than char in Cocoa (I think NSNumber is the only thing that returns a  
char), this does break returning a char from an Objective-C method. I  
can't see anyway around this short of parsing all the Cocoa headers  
to figure out when things are char and when things are BOOLs...so is  
this just an accepted issue?
