14. Colors

When specifying a color, it is possible to use its X11 Color Name (usually in the file ‘/etc/X11/rgb.txt’). You can also use a six digit hex string prefixed by a ’#’ character in the same way that you can specify colors in HTML.

All text printed by StumpWM is run through a coloring engine before being displayed. All color commands start with a ‘^’ (caret) character and apply to all text after it.

^0-9

A caret followed by a single digit number changes the foreground color to the specified color. A ‘*’ can be used to specify the normal color. See the color listing below.

^0-90-9

A caret followed by two digits sets the foreground and background color. The first digit refers to the foreground color and the second digit to the background color. A ‘*’ can be used in place of either digit to specify the normal color. See the color listing below.

^B

Turn on bright colors.

^b

Turn off bright colors.

^n

Use the normal background and foreground color.

^R

Reverse the foreground and background colors.

^r

Turn off reverse colors.

^[

Push the current colors onto the color stack. The current colors remain unchanged.

^]

Pop the colors off the color stack.

^>

Align the rest of the line to the right of the window.

^f<n>

Sets the current font to the font at index n in the screen’s font list.

^(<modifier> &rest arguments)

Allows for more complicated color settings: <modifier> can be one of :fg, :bg, :reverse, :bright, :push, :pop, :font and :>. The arguments for each modifier differ:

• :fg and :bg take a color as an argument, which can either be a numeric index into the color map or a hexadecimal color in the form of "#fff" or "#ffffff".
• :reverse and :bright take either t or nil as an argument. T enables the setting and nil disables it.
• :push and :pop take no arguments. :push pushes the current settings onto the color stack, leaving the current settings intact. :pop pops color settings off the stack, updating the current settings.
• :font takes an integer that represents an index into the screen’s list of fonts, or, possibly, a literal font object that can immediately be used. In a string you’ll probably only want to specify an integer.
• :> takes no arguments. It triggers right-alignment for the rest of the line.

^^

Print a regular caret.

The default colors are made to resemble the 16 VGA colors and are:

0 black

1 red

2 green

3 yellow

4 blue

5 magenta

6 cyan

7 white

There are only 8 colors by default but 10 available digits. The last two digits are left up to the user. Behind The Scenes Look At Colors for information on customizing colors.
