Keep all the code that you can out of the .g file. I'd like to put support code in superclasses, but would prefer not to separate the lexer and parser grammars. Is there any way to do that (without changing the Java target templates)? <http://www.antlr.org/jira/browse/ANTLR-375> seems relevant, but it is shown as not fixed. You would get the superclass for the parser only. But, as soon as you want to use superclasses, then you should really separate them out as it is easier to spot what is going on when you come back to it in 18 months time.
