[Haskell-cafe] CPP, Leopard and Haskell Objective-C bindings

[Joel Reymont]

It seems that the current approach taken by HOC is to strip  
preprocessing directives. This may not have been a problem before  
Leopard but Cocoa header files are now full of macros in most unusual  
places, e.g.

@interface NSObject (NSDeprecatedMethods)

+ (void)poseAsClass:(Class)aClass  
DEPRECATED_IN_MAC_OS_X_VERSION_10_5_AND_LATER;

@end

I'm trying to figure out the easiest way to run CPP over the header  
files before processing them in HOC.

Is there a CPP written in Haskell and packaged as a library?

Does someone have a quick Haskell solution for running CPP over a  
header file (with include paths?), redirecting into a temp file and  
reading that back into Haskell?

Should I preprocess all Cocoa header files using make and then read  
these in?

	Thanks, Joel
