Hi,
I'm playing with ANTLRWorks 1.2.1. When I try to debug my grammar, the result
is a compile error, unreachable statement. Any hints on how to correct this?
Please find the grammar and the console error message included at the bottom.
Thanks,
András
--- unreachable.g --------------------
grammar unreachable;
ID : ('a'..'z'|'A'..'Z')+ ;
DEFINES : '::=' ;
WS : (' '|'\t')+ {skip();} ;
prog: stat+ ;
stat: assignment;
assignment : leftValue WS* DEFINES WS* rightValue
{System.out.println($leftValue.value + "=" + $rightValue.value);};
leftValue returns [String value]: ID {return $ID.text;};
rightValue returns [String value]: ID {return $ID.text;}| sequence {return
$sequence.value;};
sequence returns [String value]: 'SEQUENCE' WS* '{' WS* e=rightValue
{$value=$e.value;} (WS* ',' WS* e=rightValue {$value += $e.value;})* WS* '}'
{return $value;};
