Parser

Description

This module provides the generated Happy parser for Haskell. It exports a number of parsers which may be used in any library that uses the GHC API. A common usage pattern is to initialize the parser state with a given string and then parse that string:

        runParser :: DynFlags -> String -> P a -> ParseResult a
        runParser flags str parser = unP parser parseState
        where
          filename = "<interactive>"
          location = mkRealSrcLoc (mkFastString filename) 1 1
          buffer = stringToStringBuffer str
          parseState = mkPState flags buffer location in
