[il-antlr-interest: 20762] how to stop parser on lexical error???

Hi I am trying to stop parsing on a lexical error, and it just doesn't want to stop. I have tried this thread : http://www.antlr.org/wiki/pages/viewpage.action?pageId=5341217 and it doesn't work. I am using antlr 3.1.1. I have also tried adding the catch rules in my grammar: @members { prote

ANTLR Testing is a unit testing library for ANTLR grammars using JUnit and a fluid interface. I use it on a couple of my own projects, and I have students using it as well. I released version 0.8 today. You can get it here: http://antlr-testing.sourceforge.net/ . It has some nice new features:

My use case was just traversing a tree, not matter how it looks. But having ^(. ID) could mean "anything that has an ID as its first child". No idea what would be the use case, so I know where you are coming from. Maybe just add it for the sake of completeness and so that my tree rule finally w

Hi, Not sure if this is dummy level, but I can't figure out why the presence of token Date messes up the parsing. When Date is present and not a fragment, I get EarlyExitException on inputs like "123" and "123,456." My question is primarily whether this is a bug or normal behavior. I'm sure there

I tried this out and it actually works great :) I am wondering if "bottomup" is really needed, though. I only need "topdown" as the whole structure already is encoded in the tree. So there is no need to track context for me in that way. Do you have any use case for that? Or did I get that all w
