Options.OptStream.IOOps

Description

This module defines IOOps, which is a way to abstract away IO operations required for Options.OptStream.

Synopsis

class Monad m => IOOps m where
- getArgs :: m [String]
- getProgName :: m String
- putStrLn :: String -> m ()
- die :: String -> m a
- exitSuccess :: m a

Documentation

class Monad m => IOOps m where Source #

IOOps is a typeclass that describes parts of IO used by Options.OptStream. It is meant to be represented by IO in production and a mock implementation in tests.

Methods

getArgs :: m [String] Source #

getProgName :: m String Source #

putStrLn :: String -> m () Source #

die :: String -> m a Source #
