A library for text decoration with ANSI escape sequences made easy. Decorate your terminal text expressively. Any complex data type, existing or custom, can be simply colorized by implementing the class ToEscapable, then output to terminal or converted to String using the provided functions.

Simple Example

import Data.Monoid ((<>))
import Text.EscapeArtist

underlines = Underline $ FgCyan "I am underlined" <> UnderlineOff " but I am not " <> FgMagenta "and I am over here"

putEscLn underlines

Implementing ToEscapable

import Data.Monoid ((<>))
import Text.EscapeArtist

data ABC = A | B deriving (Show, Eq)

instance ToEscapable ABC where
    toEscapable (A) = FgRed $ show A
    toEscapable (B) = FgGreen $ show B

instance (ToEscapable a) => ToEscapable (Maybe a) where
     toEscapable (Just a) = FgGreen "Just" <> Inherit " " <> FgYellow a
     toEscapable a = FgRed $ show a
