Shell Scripting With Haskell
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.
Howto
The script falls into three main parts:
- The hashbang first line:
bash #!/usr/bin/env haskellscript - Dependencies (potentially including versions):
bash --#aeson - The code:
haskell {-# LANGUAGE OverloadedStrings #-} 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.
