This repository is a version of happy which uses a recursive ascent-descent backend as described in this bachelors thesis. It uses happy-lib to do .y-file parsing and processing and only uses a different backend for RAD code generation.
Build via:
$ cabal build
$ cabal build -f -bootstrap
(depending on whether you want a bootstrapped happy (by default) or not), and perform the tests via:
$ cabal test
$ cabal test -f -bootstrap
