The knob package

Create memory-backed 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)
