Synopsis

$cparse(<text>)
$cparse(“<text>” <arguments>…)

Technical:

In the first form, <text> is a string that can contain embeded color directives. In the second form, <text> is a dword that can contain embedded color directives *and* references to $* which are satisfied by the following <arguments>. Don't forget to double up your $'s in this second format when refering to $*.

This function parses <text> according to the following table:

Color Code(s) Text Text Background
%k %K %0 black bold black black
%r %R %1 red bold red red
%g %G %2 green bold green green
%y %Y %3 yellow bold yellow yellow
%b %B %4 blue bold blue blue
%m %M %5 magenta bold magenta magenta
%p %P magenta (purple) magenta (purple)
%c %C %6 cyan bold cyan cyan
%w %W %7 while bold white white

These codes have special meanings

Color Code Meaning
%F flashing
%n Turn all colors off
%N Don't reset colors at end of string
%X Insert a literal Control-X (see example below)
%% Insert a literal %

Practical:

This is a convenient way add color to scripts without actually using the control-c character.

Returns:

<text> parsed according to the rules in the above table

Examples:

Example 1: basic colors

$cparse(bl%Bah)

returns

bl^C4ah

where ^C4 is the control-c color code for blue.

Example 2: interpolation

$cparse("This is a $$0 test" cparse)

returns

This is a cparse test

Remember that $'s are expanded before a function is called, so you have to double up the $'s to make it work properly.

Example 3: 256-colors

$cparse(%X80Testing)

returns

^X80Testing

which will render your Testing in color 80 (usually some kind of blue)

Disclaimer:

“Bold Colors” is implementation defined by your terminal emulator. You might expect any of these outcomes

  1. Bold text but ordinary color
  2. Ordinary text but bold color
  3. Bold text and bold color
  4. Ordinary text and ordinary color

(That last one is pretty lame, but believe it or not there are emulators that actually do that.) You can use 256 colors to work around this
