    warn_with_color

    I can’t guarantee this will work on legacy operating systems, but if you’re using Linux or OS/X, adding a splash of color to your console output helps in finding those ever elusive warnings:

    require "highline"
require "facet/module/alias_method_chain"

module Kernel
  def warn_with_color(message)
    warn_without_color HighLine.new.color(message.to_s, :red)
  end
  alias_method_chain :warn, :color
end

      Allright, so either on .irbc (the configuration file for your command-line ruby) or directly in your Ruby Program, right ?

      I pulled this out of Buildr, so I’m guessing directly in your Ruby Program.
