In ANTLR 4, the parsers exits successfully even if the input does match the grammer only partially. Can this behavior be changed? I would like the parser to either recognize a complete parse or fail. There may be some of the input left, but the input parsed so far must match the complete grammar.

That's probably a FAQ already. End your main rule with EOF, so it only matches if the the given text exactly can be matched by that rule.

Hi Mike,
that's not what I meant. Using EOF, input and parse must end at the same time. Without EOF, the parse may be incomplete and there may be some input left. I'd like to have a complete parse and probably some left over input.
Regards,
Armin
