I have been looking at both ANTLR and JavaCC but I can't find any main differences between the two tools, one being the ANTLR can parse C++ code. Are there any other differences

thanks
Allan

You mean that ANTLR can generate C++ as well as Java, right? Yep, that's one difference. The tools are pretty much in the same spirit, but with different styles. JavaCC grammars look very much like Java code while ANTLR grammars look more like traditional grammars. Both tools allow lots of lookahead and predicates (code that evaluates at runtime to alter the parse).
