| Summary : Access Hackage\'s package database via Data.Map
|
Description :
This module provides simple access to the Hackage database by means of
\'Data.Map\'. Suppose you wanted to implement a utility that queries the set of
available versions for a given package, the following program would do the
trick:
> import qualified Distribution.Hackage.DB as DB > import Distribution.Text (
display ) > import System.Environment ( getArgs ) > > main :: IO () > main = do
> pkgs < - getArgs > db < - DB.readHackage > let getVersions name = maybe []
DB.keys (DB.lookup name db) > mapM_ (putStrLn . unwords . map display .
getVersions) pkgs
When run, it would produce the following output:
> ./a.out containers deepseq cabal-install > 0.1.0.0 0.1.0.1 0.2.0.0 0.2.0.1
0.3.0.0 0.4.0.0 > 1.0.0.0 1.1.0.0 1.1.0.1 1.1.0.2 > 0.4.0 0.5.0 0.5.1 0.5.2
0.6.0 0.6.2 0.6.4 0.8.0 0.8.2 0.10.0 0.10.2.
