Module: Kolorit::Linux

Included in:
Windows
Defined in:
lib/kolorit/linux.rb

Overview

Color codes for Linux systems. Allow use of color methods in many different ways.

Include methods outside of main module to use them directly on string (or integer, array, hash). This is done when you call ‘require ’kolorit’‘. You can also just include it in class where you want to use it:

Examples:

Include Kolorit::Linux in just one class


class MyClass
  require 'kolorit/linux'
  include Kolorit::Linux
  # rest_of_code
end

Use color named methods


red 'Hello Red Ruby!'
# or
green 'Hello Green Ruby!'

Use colorize/kolorize methods


colorize :red, 'Hello Red Ruby!'
# or
kolorize 'Ruby goes green, again!', :green

Colorize also accept block


# colorize accept color as first argument

colorize(:green) do
  case @var = SomeClass.call_some_method
  when 'some response'
    "do_something_with_response #{@var}"
  else
    # in this situation #red has precedence over #green
    red("Returned Error for #{@var}")
  end
end

# kolorize accept string as first argument

kolorize(@result) { @result.is_a?(String) ? :green : :red }
