colorize the alr output in Emacs' compilation buffer

[Rolf Ebert]

I call 'alr build' as compile command. That does not look pretty at all,
the escape sequences are shown and not translated. So I called 'alr
--no-color build'. But that looks boring. After some research I added
the following two lines to my .emacs:

(require 'ansi-color)
(add-hook 'compilation-mode-hook 'ansi-color-for-comint-mode-on)

But that does not work neither.

Has anybody tried that before and has a solution?

Regards
