What does "m" stand for in rpsec testing?

Question

I execute:

rake spec:models

and I get:

←[32m.←[0m

Finished in 0.08304 seconds
←[32m1 example, 0 failures←[0m

I haven't seen an explication for the "32m1" or "0m" anywhere. What are they?

Answer 1

Those are ANSI escape sequences that would normally tell the console the color the output, or the background of the output.

Check out this related question for a gem you can install that will fix that: Displaying Unix color on Windows Cmd

You can read more about ANSI escape codes here.

Whoops, that link for the gems actually are for separate consoles, not gems. My bad. I used to use a gem wirble, which has been replaced by a new gem called brice. You can find brice here. Looks like I also used the win32console gem, which is what did the actual conversion of the color codes to the respective console colors. My old .irbrc file looks like this:

begin
  # load wirble
  require 'wirble'
  require 'win32console'
  include Win32::Console::ANSI

  # start wirble
  Wirble.init
  Wirble.colorize
 rescue LoadError => err
   warn "Couldn't load wirble: #{err}"
end
