name: haskellscript version: 0.2.3 synopsis: Command line tool for running Haskell scripts with a hashbang. description: This tool provides the ability to script in a shell with Haskell (including dependencies) the same way that has been possible with bash scripts or Python. . /Examples/ . Print out JSON constructed with Aeson . . Lookup weather for your current IP address . . /Prerequisites/ . A sandbox capable install of [Cabal](https://www.haskell.org/cabal/). . /Howto/ . The script falls into three main parts: . * The hashbang first line: . > #!/usr/bin/env haskellscript . * Dependencies (potentially including versions): . > --#aeson . * The code: . > import Data.Aeson > import Data.ByteString.Lazy hiding (putStrLn, unpack) > import Data.Text > import Data.Text.Encoding > jsonExample = object ["Test" .= True, "Example" .= True] > main = putStrLn $ unpack $ decodeUtf8 $ toStrict $ encode jsonExample . Note that because the dependencies specified are hashed to enable re-use it's worth specifying exact versions across multiple scripts to prevent the version used being quite old after a while. license: BSD3 license-file: LICENSE author: Sean Parsons maintainer: github@futurenotfound.com copyright: Copyright (C) 2015 Sean Parsons category: Development build-type: Simple cabal-version: >=1.10 homepage: http://github.com/seanparsons/haskellscript/ bug-reports: http://github.com/seanparsons/haskellscript/issues source-repository head type: git location: git://github.com/seanparsons/haskellscript.git executable haskellscript main-is: HaskellScript.hs build-depends: base >=4.6 && <4.9, either, directory, filepath, text, mtl, process, cryptohash hs-source-dirs: src default-language: Haskell2010
