Distribution.Hackage.DB.Parsed
Description
This module provides simple access to the Hackage database by means
of Map.
- type Hackage = Map String (Map Version GenericPackageDescription)
- readHackage :: IO Hackage
- readHackage' :: FilePath -> IO Hackage
- parseHackage :: ByteString -> Hackage
- parseUnparsedHackage :: Hackage -> Hackage
- parsePackage :: String -> Version -> ByteString -> GenericPackageDescription
- parsePackage' :: ByteString -> Either String GenericPackageDescription
Documentation
type Hackage = Map String (Map Version GenericPackageDescription) #
A Map representation of the Hackage database. Every package name
maps to a non-empty set of version, and for every version there is a
parsed Cabal file.
readHackage :: IO Hackage #
Read the Hackage database from the location determined by hackagePath
and return a Map that provides fast access to its contents.
readHackage' :: FilePath -> IO Hackage #
parseHackage :: ByteString -> Hackage #
Parse the contents of Hackage's 00-index.tar into a Hackage map.
parsePackage :: String -> Version -> ByteString -> GenericPackageDescription #
Convenience wrapper around parsePackage' to parse a single Cabal
file. Failure is reported with error.
parsePackage' :: ByteString -> Either String GenericPackageDescription #
Parse a single Cabal file.
