Re: Bison/Yacc with Objective-C ?

Graham,

Definitely not nonsense, and is the solution I will use unless I can find a more direct route. I have done this in the past for YACC to generate C++ on Windows systems. The headache with this solution is that the Xcode has a built-in rule that goes from YACC to C and tries to compile immediately. I will have to learn how to replace the built-in YACC rule with something else.

Thanks again for your suggestion,

Tom Wetmore

I do see that bison can generate C++ instead of C. Does anyone know whether there is any version of yacc or bison that has been modified to generate Objective-C? Or if there is any other parser generator available that can generate Objective-C.

That means that could be Objective-C code - you'd only need to change the file extension from .c to .m to compile it. As long as the emitted code is the only Objective-C and therefore not required to be parsed by YACC, I reckon it ought to work.
