[antlr-interest] Generator Bug: Expands $ within Comments

[Foust]

The latest beta (from 08/03/2008) expands parser variables within comments:

 

statement                           : ^(T_STMT expr?)

                                                {

 
System.out.println("STMT: ");// + $expr.text);

                                                }

 

It wouldn't be such an issue, except there are cases (like this one) where
the expansion extends over multiple lines, so temporarily-commenting out a
portion of a line using a line comment as above causes a compilation problem
in the target language:

 

   System.out.println("STMT: ");
//(object1!=null?(input.getTokenStream().toString(

           input.getTreeAdaptor().getTokenStartIndex(object1.start),

           input.getTreeAdaptor().getTokenStopIndex(object1.start))):null));
