Happy is a parser generator for Haskell 98 (and later).
Happy is built using Cabal. First install GHC, then:
$ cabal install
If you obtained the development version from https://github.com/simonmar/happy/, install via:
$ make sdist && cabal install
Complete documentation can be found in the directory 'doc', in DocBook XML format. To format the documentation, the DocBook-Tools suite (see https://github.com/docbook/wiki/wiki/DocBookTools) provides all the bits & pieces you need. Alternatively, pre-formatted documentation is available from Happy's homepage (URL above).
The directory 'examples' contains some example parsers that use Happy.
