Documentation

color :: ColorIntensity -> Color -> String -> String Source #

Wrap a string in ANSI codes to set and reset foreground colour.

bgColor :: ColorIntensity -> Color -> String -> String Source #

Wrap a string in ANSI codes to set and reset background colour.

data Color #

ANSI's eight standard colors. They come in two intensities, which are controlled by ColorIntensity. Many terminals allow the colors of the standard palette to be customised, so that, for example, setSGR [ SetColor Foreground Vivid Green ] may not result in bright green characters.
