[Pyobjc-dev] FourCharCodes vs. PyObjC

[Bob I. <bo...@re...>]

In Python, four char codes are strings of length four.  PyObjC sees the 
signature of FourCharCode as an unsigned integer.  This is bad, AFAIK 
there is no "signature character" that we can use to specify a length 
of four.. so basically I have some 30 or so, maybe more, mappings to 
write just to provide FourCharCode to string of length four 
compatibility.

This is mostly a question for Ronald I guess, but how would this best 
be done?  Basically what needs to be done is a lot of PyMac_GetOSType 
and PyMac_BuildOSType all over the place.. or else people will have to 
struct.unpack('L', fourCharCode)[0] everywhere, which is not fun.  A 
potential solution to this would be to add a signature character, or to 
allow length of 4 strings for any uint32.. but I'd also like to see 
things come out of PyObjC as length of four character strings.

Also, how can I transparently bridge AEDesc with 
NSAppleEventDescriptor?  They're basically the same thing.
