parser package:ghc

A pure interface to the module parser.

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 :: ParserOpts -> String -> P a -> ParseResult a
runParser opts str parser = unP parser parseState
where
filename = "<interactive>"
location = mkRealSrcLoc (mkFastString filename) 1 1
buffer = stringToStringBuffer str
parseState = initParserState opts buffer location

Parsers for unit/module identifiers

Parse a response file into arguments.

Parser options. See mkParserOpts to construct this.

Extracts the flags needed for parsing

Errors from the Cmm parser
