[antlr-interest] Separating text from comment in a source file

[Mark Venbrux]

Hi,

I would like to separate text from comment in a source file. In the end I
would like to keep the source code as is, and to process the comments. I
tried the following grammar, but it doesn't work as expected.
Warning: [17:01:59] warning(201): d:\temp\antlr.g:26:40: The following
alternatives are unreachable: 1
This is about the TEXT rule.

Comments are picked up, but text is skipped. What is wrong here?

Cheers,
Mark

grammar antlr;
options {filter=true;}
@header {
package test;
}

@lexer::header {package test;}

@members {
}

file:  (

               COMMENT  {System.out.println("CO: "+$COMMENT.text);}
       |       TEXT     {System.out.println("TE: "+$TEXT.text);}
       )*
       ;



COMMENT
    :   '/*' (options {greedy=false;} : . )* '*/'
    ;

TEXT
       :  (options {greedy=false;} : . )+
       ;
