Hello,
I need to interact with some other program, and wrote the following code:
module Main where
import System.Process
import System.IO
main :: IO ()
main = do
putStrLn "Running proc9..."
(inp,out,err,pid) <- runInteractiveProcess "prog1" [] Nothing Nothing
hSetBuffering inp LineBuffering
hSetBuffering out LineBuffering
hSetBuffering err LineBuffering
hPutStrLn inp "1"
a <- hGetLine out
hPutStrLn inp a
a <- hGetLine out
waitForProcess pid
putStrLn a
But it does not work as I expected. As long as there is no need to put some
input after having received some output it is no problem, but real interaction
seems not possible.
Is there a solution to work with the Handles as with stdin,... ?
using ghc 6.6 on Windows
Thanks in advance for your help.
