Not all of the ANSI escape codes are provided by this module, but most (if not all) of the popular and well supported ones are. For a full list, have a look at the current version of the API. Each supported escape code or family of codes has a corresponding function that comes in three variants:


A full example is available, but for a taste of how the library works try the following code:

import System.Console.ANSI

main = do
    setCursorPosition 5 0
    setTitle "ANSI Terminal Short Example"

    setSGR [ SetConsoleIntensity BoldIntensity
           , SetColor Foreground Vivid Red
    putStr "Hello"
    setSGR [ SetConsoleIntensity NormalIntensity
           , SetColor Foreground Vivid White
           , SetColor Background Dull Blue
    putStrLn "World!"
