simple-cmd-args: Simple command args parsing and execution
This is a small wrapper over optparse-applicative which allows combining args parsers directly with IO commands. For subcommands this can avoid type boilerplate. It also provides a few functions for common Mod combinations.

Readme for simple-cmd-args-0.1.1
[back to package description]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...")
]
