effectful-2.4.0.0: src/Effectful/Console/ByteString/Lazy.hs

-- | Lifted functions from "Data.ByteString.Lazy.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.Lazy.Char8 (ByteString)
-- > import Data.ByteString.Lazy.Char8 qualified as LBS8
-- > import Effectful.Console.ByteString.Lazy (Console)
-- > import Effectful.Console.ByteString.Lazy qualified as Console
--
module Effectful.Console.ByteString.Lazy
  ( -- * Effect
    Console

    -- ** Handlers
  , runConsole

    -- * Operations
  , getContents
  , putStr
  , putStrLn
  , interact
  ) where

import Prelude hiding
  ( getContents
  , interact
  , putStr
  , putStrLn
  )
