[antlr-interest] Template Rewrite Rule consumes one more Token than expected

[Felix Dorner]

Hi,

I have a problem in a template grammar that's rewriting the tokenstream. 
I don't understand why the input:

a * b; \n

returns "where's the semicolon?", i.e. the trailing semicolon is eaten 
up too...

Thanks for your help. Felix.


Here's the test grammars:

grammar Test;

options{
output=AST;
ASTLabelType=CommonTree;
}

statement
    :    expression ';'!
    ;
expression
    :    ID '*'^ ID;
   
ID    :    'a'..'z';

WS
    : ( ' ' | '\t' | '\r' | '\n' )+ { $channel = HIDDEN; } ;



tree grammar TestTree;

options{
tokenVocab=Test;
output=template;
ASTLabelType=CommonTree;
rewrite=true;
}


statement
    :    expression;
   
expression
    :    ^('*' ID ID)
            -> template(text={"where's the semicolon?"}) "<text>"
    ;
