I was just discussing this with some folks here at PyCon. Clang has a library interface (libclang): http://clang.llvm.org/doxygen/group__CINDEX.html There's Python bindings for it; I'm sure the author would like some company =) https://bitbucket.org/binet/py-clang/ Cheers P -- http://mail.python.org/mailman/listinfo/python-list
