Mixlib::Config

Mixlib::Config provides a class-based configuration object, like the one used in Chef. To use in your project:

  require 'rubygems'
  require 'mixlib/config'

  class MyConfig
    extend(Mixlib::Config)
    configure do |c|
      c[:first_value] = 'something'
      c[:other_value] = 'something_else'
    end
  end

Or…

  class MyConfig
    extend(Mixlib::Config)

    first_value 'something'
    other_value 'something_else'
  end

To check a configuration variable:

  MyConfig.first_value   # returns 'something'
  MyConfig[:first_value] # returns 'something'

To change a configuration variable at runtime:

  MyConfig.first_value('foobar')    # sets first_value to 'foobar'
  MyConfig[:first_value] = 'foobar' # sets first_value to 'foobar'

You should populate your class with the default values for every configuration variable that might be accessed. If you try and access a variable that does not exist, Mixlib::Config will throw an <ArgumentError>.

To load a ruby configuration file (which will evaluate in the context of your configuration class):

  MyConfig.from_file('your_config_file.rb')

Enjoy!
