You need to add EOF token as last element of your start rule.

Even if i give an invalid character at the last the parser is not throwing the exception. The below is my grammar :- // *************************** grammar test; globalnumber : phonedigit (NEWLINE)* ; phonedigit : (DIGIT)* ; NEWLINE : '\n' ; DIGIT : (0-9) ALPHA : ('a'-'z') | ('A'-'Z'); // *************************** Here if we notice that the NEWLINE is an optional rule. , when I give the input as " 12345a " for the rule "globalnumber" then the parser is not throwing any exception. i checked the parser code its just consuming those tokens . :-( When I make the NEWLINE as mandatory then its working fine. but i dont want that to be a mandatory RULE. Thanx a lot for reading this query expecting your response.
