RSpec. How to color the piped or redirected output?

In versions of RSpec before 2.0 I could pipe the color output to less or redirect it to a file. In order to do it I simply have to set the RSPEC_COLOR environment variable to true. However, in the new main version of the framework this variable has stopped to define the output type (color or monchrome). Is t开发者_如何学运维here any way to pipe or redirect the color in RSpec 2.0 and higher?

Thanks.

Debian GNU/Linux 5.0.7;

Ruby 1.9.2;

RSpec 2.4.0.

I found the answer by myself.

One should use the tty configuration option to achieve the effect.

Here's the example:

# spec/spec_helper.rb

RSpec.configure do |config|
  config.tty = true
end

The answer in the question is the correct one:

# spec/spec_helper.rb

RSpec.configure do |config|
  config.tty = true
end

Then rspec | grep --color="never" something keeps the coloring.

By looking at the sources, it seems that the color_enabled configuration option is now in the Configuration module of RSpec. However, if the output is not done to a tty, color is disabled.

My suggestion would be to set color_enabled = true and to monkey patch the RSpec Configuration module so that is works even when not outputting to a tty:

module RSpec   
  module Core
    class Configuration
      def color_enabled
        true
      end
    end
  end
end

This is not the nicest way, though. This is also untested and I think that monkey patching rspec is not the easiest thing to do because usually tests are run via the dedicated command line tool.

Maybe you could open a bug report to the maintainer and ask for a force_color_enabled option ? It would probably be very quick to implement...

Good Luck and Happy Coding !

It's as simple as:

# spec/spec_helper.rb

RSpec.configure do |config|
  config.color_enabled = true
end
