Simple terminal string styling in Haskell, in the style of JavaScript's sindresorhus/chalk and sindresorhus/ansi-styles.
cabal install chalk
(Image borrowed from sindresorhus/ansi-styles.) Use any of the styling functions above to get the effect you want.
Since these are functions, you can compose them as you like.
import System.Console.Chalk
main = do
putStrLn $ green "This is going to be green."
putStrLn $ (underline . blue) "This is going to be blue and underlined."The type of the styling functions is (Monoid m, IsString m) => m -> m, so you
can use any type that has an instance of Monoid and IsString, which probably covers
what you will use this for.
