Hi
getChar doesn't return until I press Enter. I need something that returns immediately after I press any key.
It's a problem with buffering:
hSetBuffering stdin NoBuffering
This usually doesn't work on Windows: GHC 6.4.2 and 6.6: requires <enter> Hugs (console) Sept. 2006: requires <enter> WinHugs (GUI) Sept. 2006: works as expected But it seems to work on Linux: GHC 6.4.1 on Ubuntu 6.06: works as expected GHC 6.6 on Ubuntu 6.06: works as expected I am really interested in hearing of a solution that works on all platforms.
import IO main = do hSetBuffering stdin NoBuffering hGetChar stdin
