Hi all. Is anybody familiar with the GCC lexer, locate at libcpp/lex.c in the GCC source tree? http://gcc.gnu.org/viewcvs/trunk/libcpp/ http://gcc.gnu.org/onlinedocs/cppinternals/Lexer.html#Lexer I'd like to do lexical analysis on some C source code for educational purposes, but I am having troubles in finding entry points to the libcpp library. As I read at http://gcc.gnu.org/onlinedocs/cppinternals/Lexer.html#Lexer , cpp_get_token() should be the main API call, defined at libcpp/macro.c , but I can't locate client code in GCC sources (which is, where the lexer is called), nor testcases that could illustrate me, for instance, how to cook the input to get it into a cpp_reader struct (the type required for cpp_get_token()'s input). So: what's the entry point to libcpp? Where do I find examples of calls, if any? Cheers, Giovanni PS: please CC your reply to me, since I am not a subscriber of gcc-help.
