Using lexertl in Wave seems like a very nice first step to getting the library accepted into boost. How would I go about doing this?
To make it easy I wrote the C++ lexer based on lexertl (fitting into Wave) and changed the list_includes sample in Wave (libs/wave/samples/list_includes) to use it. It's in the Boost CVS::HEAD. Unfortunately, I was not able to make it working correctly (I probably got some of the regex's wrong - I just copied them over from the Slex lexer). I had a very hard time to figure out, which of the token definitions made the lexertl library choke (I've got some nasty assertions from the VC8 debug STL). And even after removing the offending regex token definitions, I got errors from the test (see below). Would it be possible to improve debug support for the library? In any case I'm not blaming lexertl, all errors are mine :-P - Writing the lexer itself was a simple task. To make testing of the lexer itself a bit easier I added a selfcontained test: libs/wave/test/testlexers/test_lexertl_lexer.cpp, verifying the correctness in the context of Wave. This test is a good starting point for debugging. Anyway I checked my current state into the CVS, just in case somebody wants to take over. Regards Hartmut
