Basic types and values

Types

Color types

Sourcetype color4 = {
  1. r4 : bool;
  2. g4 : bool;
  3. b4 : bool;
  4. intensity4 : bool;
}

The type of 4-bits colors. They are informally rgb colors where each component is in a scale from 0 to 1, with an additionnal intensity bit.

Sourcetype cube6 = {
  1. r6 : int;
  2. g6 : int;
  3. b6 : int;
}

The type of rgb colors with each component in [0; 5]. This is used to encode the 6*6*6 color cube of 8-bits colors?

Sourcetype color8 =
  1. | Standard of color4
  2. | Cube6 of cube6
  3. | Grayscale of int

The type of a 8-bits color. Such a color is either a standard color, a 6*6*6 rgb color or some kind of grey on a 24-steps grayscale. Thus, the paramter of Grayscale should be in [0; 23]

Sourcetype color24 = {
  1. r24 : int;
  2. g24 : int;
  3. b24 : int;
}

The type of 24-bits colors. Each component belongs to [0; 255].

Sourcetype color =
  1. | C4 of color4
  2. | C8 of color8
  3. | C24 of color24

The type of a color that can be a 4-, 8- or 24-bits color.

Sourcetype style =
  1. | Reset
  2. | Bold
  3. | Faint
  4. | Faint_bold_off
  5. | Italic
  6. | Italic_fraktur_off
  7. | Fraktur
  8. | DoubleUnderlined
  9. | Underlined
  10. | Underlined_off
  11. | Reverse_video
  12. | Reverse_video_off
  13. | Conceal
  14. | Conceal_off
  15. | Crossed_out
  16. | Crossed_out_off
  17. | Framed
  18. | Framed_encircled_off
  19. | Encircled
  20. | Overlined
  21. | Overlined_off
  22. | Default_font
  23. | Font of int
  24. | Fg of color
  25. | Default_fg
  26. | Bg of color
  27. | Default_bg

All style sequences that are implemented.

Sourceval green : color4
Sourceval blue : color4
Sourceval yellow : color4
Sourceval magenta : color4
Sourceval cyan : color4
Sourceval white : color4
High intensity 4-bits colors
Sourceval hi_black : color4
Sourceval hi_red : color4
Sourceval hi_green : color4
Sourceval hi_blue : color4
Sourceval hi_yellow : color4
Sourceval hi_magenta : color4

Standard palettes types

Sourcetype rgb = int * int * int
Sourcemodule Color4Map : sig ... end
Sourcemodule Color8Map : sig ... end
Sourcetype color_palette =
  1. | VGA
  2. | CMD
  3. | Terminal_app
  4. | PuTTY
  5. | MIRC
  6. | Xterm
  7. | X
  8. | Ubuntu
  9. | Custom_palette of rgb Color4Map.t

The kind of palette the terminal uses. It is used to match a 4-bits color to a rgb color. This is useful to find the clostest 4-bits color to a rgb color, according to the actual colors.
