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.
