I've created a Parsing Toolkit (for JavaScript) which I believe fulfills 7/10 of the requirements described. Chevrotain - https://github.com/SAP/chevrotain https://github.com/SAP/chevrotain The list of features can be found here: - https://sap.github.io/chevrotain/docs/features/blazing_fast.html https://sap.github.io/chevrotain/docs/features/blazing_fast.... What is interesting imho is that Chevrotain is not a Parser Generator nor a Parser Combinator. It is a tool that makes it easier to craft hand built recursive decent parsers rather than a whole new level of abstraction.
