execParser :: ParserInfo a -> IO a #
Run a program description.
Parse command line arguments. Display help text and exit if any parse error occurs.
prefs :: PrefsMod -> ParserPrefs #
Create a ParserPrefs given a modifier
Show the help text if the user enters only the program name or subcommand.
This will suppress a "Missing:" error and show the full usage instead if a user just types the name of the program.
optsParser :: Parser Opts Source #
