Cucumber's ANSI colors messing up emacs compilation buffer

Question

When working in Emacs, I use the compile command (F12 by default) to run programs. When I run Cucumber in Emacs, Cucumber spits out ANSI colors that the Emacs compilation mode doesn't interpret. The result is ugly and hard to read. Here's a snippet of the *compilation* buffer showing the ugly:

^[[31m(::) failed steps (::)^[[0m 

The command I'm using:

( cd ~/lab/rails/todolist && rake cucumber:all ) 

Versions:

• Emacs 23.1
• Cucumber 0.8.3
• Cucumber-rails 0.3.2

The world would be sunshine and birds singing if I could:

• Get Emacs to interpret ANSI color codes in its compilation buffer, or
• Get Cucumber to stop spitting out ANSI color codes

Any ideas?

I use this to turn on ansi color interpretation in my compilation buffer:

(require 'ansi-color) (defun colorize-compilation-buffer ()   (let ((inhibit-read-only t))     (ansi-color-apply-on-region (point-min) (point-max)))) (add-hook 'compilation-filter-hook 'colorize-compilation-buffer)
