This gem adds methods to colorize strings using ansi escape codes. The gem works by adding methods to the standard String class. All added methods start with the prefix 'ansi_' and continue with one of the symbols defined in the ANSI_CMD hash in ansi_colors.rb.
Example:
require 'ansi_colors'
puts "red coloured string".ansi_red
puts "white and bold string".ansi_white.ansi_bold
