Welcome to the File Input Output in Haskell page! Here, you'll find the source code for this program as well as a description of how the program works.
module Main where
import System.IO
main :: IO ()
main = do
-- write
handle <- openFile "output.txt" ReadWriteMode
hPutStr handle "file contents"
hClose handle
-- read
handle <- openFile "output.txt" ReadWriteMode
value <- hGetContents handle
-- Print the contents of the file that was read.
-- Haskell reads the file lazily, so the value must be printed before the handle is closed
putStrLn value
hClose handle
