Hi Induh, usually what people do is write an Abstract Syntax Tree (AST) grammar which constructs an AST and then you can use different AST parsers which have the different actions.
Or you could use try this http://www.antlr.org/wiki/display/ANTLR3/Composite+Grammars BR, Paul Indhu Bharathi schrieb: > > Hi, > > > > Is there a way to separate grammar and actions into two different > files?
