Haskell cross-platform getChar with NoBuffering
Comment

To get a single character input in Haskell with NoBuffering
and support for cross-platform usage, you can make use of the hSetBuffering
function from the System.IO
module. Here's an example:
haskellimport System.IO
main :: IO ()
main = do
-- Set buffering mode to NoBuffering
hSetBuffering stdin NoBuffering
-- Get a single character from the user
c <- getChar
putStrLn ""
putStrLn $ "You entered: " ++ [c]
In this example, hSetBuffering stdin NoBuffering
is used to set the buffering mode of the standard input (stdin
) to NoBuffering
. This ensures that the input is read character-by-character without buffering.
The getChar
function is then used to read a single character from the user. The character is stored in the variable c
. Finally, the program outputs the entered character.
This code should work on both Windows and Unix-like systems, providing you with a cross-platform solution for reading a single character input with NoBuffering
in Haskell.
