Description

Lifted functions from Data.ByteString.Char8 that are related to standard streams. Like the original module, you probably want to import this module qualified to avoid name clashes with the functions provided by Prelude, e.g.:

import Data.ByteString (ByteString)
import qualified Data.ByteString.Char8 as BS8
import Effectful.Console.ByteString (Console)
import qualified Effectful.Console.ByteString as Console

Synopsis

data Console :: Effect
runConsole :: IOE :> es => Eff (Console ': es) a -> Eff es a
getLine :: Console :> es => Eff es ByteString
getContents :: Console :> es => Eff es ByteString
putStr :: Console :> es => ByteString -> Eff es ()
putStrLn :: Console :> es => ByteString -> Eff es ()
interact :: Console :> es => (ByteString -> ByteString) -> Eff es ()

Effect

data Console :: Effect Source #

An effect for reading from/writing to stdin, stdout or stderr.

Instances
