PetitParser

PetitParser combines ideas from scannerless parsing, parser combinators, parsing expression grammars and packrat parsers to model grammars and parsers as objects that can be reconfigured dynamically.

The version of PetitParser that is integrated into GT is PetitParser2 (AKA PP2) by Jan Kurš. It builds on and extends the original PetitParser framework by Lukas Renggli, in particular to make it easy to implement an Island parser
