  Examples for the book “Alex and Happy”

I have been struggling for a few days to figure out how to do this. The majority of resources for Alex / Happy seem to be very outdated, but I've had the most luck with this one: https://github.com/jmoy/alexhappy/blob/master/whitespace/Lexer.x

  A simple and lazy programming language with Damas-Hindley-Milner type inference and higher kinded types.

I should be able to look at the repo later today. Maybe I'll spot the problem. In any case I have a project which does use Alex and Happy in a "monadic way" so you should be able to compare it against something. And maybe find the problem on your own. You can check it out here https://github.com/Taskkill/frea/tree/main/src/Compiler/Parser Hope it might help as I don't really have any self-promoting intentions.
