What is tricky with analyzing C are macros and preprocessors directive.
srcML does a satisfactory job. But indeed, having a solution based on PetitParser is indeed promising.

Yes, and I don't know what to do, and would like to know if you or someone else have any idea of how to solve it. I will think some approach, but if you have some idea to share it would be better so I go directly to a good solution. I'm thinking that to feed the parser I'll have to preprocess the string with another parser, and make a string to string conversion by having a set of defines and paths so that #includes and #ifdefs work. But probably I'll need a cache because the generated string will be huge.

What do you think?

Can't macros and preprocessor directives be represented as just another nodes in the AST?

The idea of this work is to be able to feed the parser with C headers and automagically get the C bindings done in smalltalk.
