simple-cmd: Simple String-based process commands

[ bsd3, library, system ] [ Propose Tags ]

Thin wrappers over System.Process (readProcess, readProcessWithExitCode, and rawSystem). The idea is to provide some simple common idioms for easy calling out to commands from programs. For more advanced shell-scripting or streaming use turtle, shelly, command, etc.

Build Status Hackage

simple-cmd

Some simple String wrappers of readProcess, readProcessWithExitCode, rawSystem from the Haskell process library.

Usage

import SimpleCmd
cmd_ :: String -> [String] -> IO ()

outputs to stdout. For example

cmd_ "git" ["clone", url]

This can shortened to git_ "clone" [url].

cmd :: String -> [String] -> IO String

returns stdout as a String.

There are also cmdBool, cmdMaybe, cmdList, shell, and others.

Other examples:

gitBranch :: IO String
grep_ pat file :: IO Bool
sudo c args :: IO ()

See the library documentation for more details.
