Tips for using ANTLR v3 generated files in Flash Builder 4.5.1

Question

Following these instructions , I am trying to use the ANTLR * .as files created in the current Flash Builder 4.5.1 project.

So I added this ANTLR Actionscript to my project - no problem.

I compiled the lexer / parser specifications using ANTLRWorks without any problems.

I added a language parameter to the * .g source file so that ANTLR generates ActionScript sources:

options { backtrack = true; memoize = true; k=2; output = AST; language=ActionScript; // Added this ASTLabelType = CommonTree; } 

Unfortunately, the ANTLR / ANTLRworks generated ActionScript code does not work:

To pop up statements read as follows catch (RecognitionException re) , but should look like this: catch ( re:RecognitionException ) .

In addition, Flash Builder complains about using an array here:

 public override function get tokenNames():Array { return PhpParser.tokenNames; } 

Can someone confirm these problems and possibly give hints how to solve them?

UPDATE-1

A quick look at ANTLR v3.3 sources showed this template code [line 142 @ ActionScript.stg]:

 catch ( re:RecognitionException ) 

So the current 3.3 branch seems to know the correct syntax.

Unfortunately, the current ANTLRworks 1.4.2, which includes branch 3.3, fails.

Terence Parr, ANTLR project manager has just confirmed that ANTLRworks needs a new compilation. Thanks for the great support!
