[Python-Dev] Python keywords (was Lockstep iteration !) (original) (raw)

This is an alternative approach that we should certainly consider. We could use ANTLR (www.antlr.org) as our parser generator, and have it generate Java for JPython, and C++ for CPython. This would be a good chunk of work, and it's something I really don't have time to pursue. I don't even have time to pursue the idea about moving keyword recognition into the lexer.

I'm just not sure if you want to bother introducing C++ into the Python codebase solely to only have one parser for CPython and JPython.

Yet another reason why it would be nice to (eventually) merge the parsing technology in CPython and JPython.
