Engage! is an event-based parser generator. As far as I know, this is the only event-based parser generator in existence (please tell me if I'm wrong, would be glad to hear of similar projects), even though event-based parsers like SAX or RxParse are not really rarities. It was designed and developed as an experiment and published at the REBLS workshop at SPLASH 2019. The PDF of the paper is freely available, it contains a more detailed and precise description of the idea, some implementation details and empirical comparison of parsers.
