simple-cmd-args

A thin layer over optparse-applicative that avoids type plumbing for subcommands by using Parser (IO ()).

Usage

import SimpleCmdArgs
import Control.Applicative (some)
import SimpleCmd (cmd_)

main =
  simpleCmdArgs Nothing "my example tool" "Longer description..." $
  subcommands
    [ Subcommand "echo" "Print name" $ putStrLn <$> strArg "NAME"
    , Subcommand "ls" "Touch FILE" $ cmd_ "ls" <$> some (strArg "FILE...")
    ]
