Description
This module provides simple access to the Hackage database by means
of Map
.
- type Hackage = Map String (Map Version ByteString)
- readHackage :: IO Hackage
- readHackage' :: FilePath -> IO Hackage
- parseHackage :: ByteString -> Hackage
- hackagePath :: IO FilePath
Documentation
type Hackage = Map String (Map Version ByteString) Source
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
Cabal file stored as a (lazy) ByteString
.
readHackage :: IO Hackage Source
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 Source
parseHackage :: ByteString -> Hackage Source
Parse the contents of Hackage's 00-index.tar
into a Hackage
map.
hackagePath :: IO FilePath Source
Determine the default path of the Hackage database, which typically
resides at "$HOME/.cabal/packages/hackage.haskell.org/00-index.tar"
.
Running the command "cabal update"
will keep that file up-to-date.
