Hi, Just pushed 3.0ea7: http://www.antlr.org/download/antlr-3.0ea1.tar.gz and examples: http://www.antlr.org/download/examples-v3.tar.gz The ruby example is just my start on it...python grammar was ported to v3, but I'm not sure it's right yet. Enjoy. Many many updates in 3.0ea7. See the README.txt Ter
