Fontify: coloring rgb hex code by its value

Fontify: coloring rgb hex code by its value

[Xah]

i seems to recall that there's a module that will fontify a hex color
code by its value.
That is, if i have this line in my .css file:

pre.php {border-color:#2e8b57}

then the “#2e8b57” is colored using that value.

anyone know what's the name of this module or where can i get it?

A short code showing can this can be written will also be appreciated.

Thanks.

I believe this is done in the code for `list-colors-display'. That could be one
place to start. I do the same thing in some of my code, for example this:

(defun icicle-make-color-candidate (color-name &optional hex-rgb)
  (let ((rgb-string (or hex-rgb (hexrgb-color-name-to-hex color-name))))
    (put-text-property 0 (length rgb-string) 'face
                       (cons 'background-color rgb-string)
                       rgb-string)
    (list (list color-name rgb-string))))

That is in icicles-cmd.el:
http://www.emacswiki.org/cgi-bin/wiki/icicles-cmd.el

It uses code in hexrgb.el:

See also command `palette' of palette.el, for similar code:

Here's what I have in my .emacs (I culled of the net somewhere a while back).

I'm sure you can adapt this to whatever mode you want.

;;;======================================================================
;;; automatically color hex color strings
(defvar hexcolor-keywords
  '(("#[abcdef[:digit:]]\\{6\\}"
     (0 (put-text-property (match-beginning 0)
			   (match-end 0)
			   'face (list :background
				       (match-string-no-properties 0)))))))

(defun hexcolor-add-to-font-lock ()
  (font-lock-add-keywords nil hexcolor-keywords))
(add-hook 'emacs-lisp-mode-hook 'hexcolor-add-to-font-lock)
(add-hook 'nxml-mode-hook 'hexcolor-add-to-font-lock)

probably from http://www.emacswiki.org/cgi-bin/emacs-en/HexColour

It contains a few enhanced versions, as well.
