ghc-turtle
Shell programming, Haskell-style
'turtle' is a reimplementation of the Unix command line environment in Haskell so that you can use Haskell as both a shell and a scripting language. Features include: * Batteries included: Command an extended suite of predefined utilities * Interoperability: You can still run external shell commands * Portability: Works on Windows, OS X, and Linux * Exception safety: Safely acquire and release resources * Streaming: Transform or fold command output in constant space * Patterns: Use typed regular expressions that can parse structured values * Formatting: Type-safe 'printf'-style text formatting * Modern: Supports 'text' Read "Turtle.Tutorial" for a detailed tutorial or "Turtle.Prelude" for a quick-start guide 'turtle' is designed to be beginner-friendly, but as a result lacks certain features, like tracing commands. If you feel comfortable using 'turtle' then you should also check out the 'Shelly' library which provides similar functionality.
