The (term ansi-color) module generates ANSI escape sequences for colors. Here is an example of the module's use:
method one: safer, since you know the colors
will get reset
(display (colorize-string "Hello!\n" 'RED 'BOLD 'ON-BLUE))
method two: insert the colors by hand
(for-each display
(list (color 'RED 'BOLD 'ON-BLUE)
"Hello!"
(color 'RESET))) color . lst | [Function] |
Returns a string containing the ANSI escape sequence for producing the requested set of attributes.
The allowed values for the attributes are listed below. Unknown attributes are ignored.
CLEAR and RESET are allowed and equivalent.
BOLD makes text bold, and DARK reverses this. UNDERLINE and UNDERSCORE are equivalent. BLINK makes the text blink. REVERSE invokes reverse video. CONCEALED hides output (as for getting passwords, etc.).
BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE
ON-BLACK, ON-RED, ON-GREEN, ON-YELLOW, ON-BLUE, ON-MAGENTA, ON-CYAN, ON-WHITE
colorize-string str . color-list | [Function] |
Returns a copy of str colorized using ANSI escape sequences according to the attributes specified in color-list. At the end of the returned string, the color attributes will be reset such that subsequent output will not have any colors in effect.
The allowed values for the attributes are listed in the documentation for the color function.
