As a start, with a few lines of Python code after the doxyparser.parse(file) calls in the script, you can do something like: # start code to autogenerate wxc.h wxc_header = "" for aclass in doxyparse.classes: for amethod in methods: self_ref = "TSelf" if amethod.name == "Create": self_ref = "TClass" wxc_header += "%s(%s) " % (self_ref, aclass.name) else: wxc_header += "%s " % (wxc_type_for_type(amethod.return_type) wxc_header += "%s_%s( %s _obj" % (aclass.name, amethod.name, self_ref + (" + aclass.name + ")") for param in amethod.params: wxc_header += ", %s %s" % (wxc_type_for_type(param["type"]), "_" + param["declname"]) # Note: uncomment this if you support adding default values # if "defval" in param: # wxc_header += "=" + param["defval"] wxc_header += " );\n" wxc_file = open("wxc.h", "wb") wxc_file.write(wxc_header) wxc_file.close() # end code This is all just pseudo-code, and methods like wxc_type_for_type would need implemented, and you'd also need to probably work out some special logic for constructors, a list of classes to exclude, etc. but this should give you an idea of how to start things off. Ideally you'd actually have your own generate_c_bindings.py file that does an "import doxyparser", then runs "doxyparse.parse()" itself rather than extending the doxymlparser.py script, but anyway, just some ideas.
