The knob package

[ Tags: library, mit, system ] [ Propose Tags ]

Create memory-backed IO.Handles, referencing virtual files. This is mostly useful for testing Handle-based APIs without having to interact with the filesystem.

import Data.ByteString (pack)
import Data.Knob
import System.IO

main = do
    knob <- newKnob (pack [])
    h <- newFileHandle knob "test.txt" WriteMode
    hPutStrLn h "Hello world!"
    hClose h
    bytes <- Data.Knob.getContents knob
    putStrLn ("Wrote bytes: " ++ show bytes)
