Like `yacc', it takes a file containing an annotated BNF specification +of a grammar and produces a Haskell module containing a parser for the grammar. + +Happy is flexible: you can have several Happy parsers in the same program, +and several entry points to a single grammar. Happy can work in conjunction +with a lexical analyser supplied by the user (either hand-written or generated +by another program), or it can parse a stream of characters directly (but +this isn't practical in most cases). + +As of version 1.5, Happy is capable of parsing full Haskell. We have a +Haskell parser that uses Happy, which will shortly be part of the library +collection distributed with GHC. +EOF |
