Rainbow.Colors

Ordinarily you should not need this module; typically you will just import Rainbow, which re-exports the most useful things from this module. This module also contains data constructors that Rainbow does not re-export.

8 color

noColor8 :: Color8

Resets the color (foreground or background, as appropriate) to the default for your terminal. Usually you will not need this, as each Chunk starts out with the terminal's default colors.

black8 :: Color8

red8 :: Color8

green8 :: Color8

yellow8 :: Color8

blue8 :: Color8

magenta8 :: Color8

cyan8 :: Color8

white8 :: Color8

256 color

noColor256 :: Color256

Resets the color (foreground or background, as appropriate) to the default for your terminal. Usually you will not need this, as each Chunk starts out with the terminal's default colors.

grey :: Color256

brightRed :: Color256

brightGreen :: Color256

brightYellow :: Color256

brightBlue :: Color256

brightMagenta :: Color256

brightCyan :: Color256

brightWhite :: Color256

Both 8- and 256-color terminals

data Radiant

A Radiant affects both 8- and 256-color terminals. (It does not necessarily affect both the foreground and background; whether it affects the foreground, background, or both depends upon the context in which it is used.)

Constructors

Radiant

Fields

rad8 :: Color8

rad256 :: Maybe Color256

If Nothing, use the rad8 color on 256-color terminals.

Instances

Eq Radiant

Ord Radiant

Show Radiant

Color Radiant

Affects the foreground and background of both 8- and 256-color terminals.

both :: Color8 -> Radiant

A Radiant with the same color for both 8- and 256-color terminals.

noColorRadiant :: Radiant

A Radiant that uses the terminal's default colors for both 8- and 256-color terminals.

black :: Radiant

red :: Radiant

green :: Radiant

yellow :: Radiant

blue :: Radiant

magenta :: Radiant

cyan :: Radiant

white :: Radiant

class Color a where

Changing colors. Instances of this class affect the background or the foreground color. For example, to get a Chunk that changes the background to red, use back red; for the foreground, use fore red. Whether 8-color or 256-color terminals (or both) are affected depends on the particular instance.

Because Word8 is an instance of Color, you can use literals to affect the color of 256-color terminals. For example, if you have a 256 color terminal:

putChunkLn $ "muddy yellow background" <> back (100 :: Word8)

This example would not affect an 8-color terminal, as the Word8 instance affects 256-color terminals only.

Methods

back :: a -> Chunk

Create a Chunk that affects the background color only.

fore :: a -> Chunk

Create a Chunk that affects the foreground color only.

Instances

Color Word8

Affects the foreground and background of 256-color terminals.

Color Color256

Color Color8

Color Enum8

Affects the foreground and background of 8-color terminals.

Color Radiant

Affects the foreground and background of both 8- and 256-color terminals.
