# module Kramdown::Utils::Configurable

Methods for registering configurable extensions.

### Public Instance Methods

configurable(name) click to toggle source

Create a new configurable extension called `name`.

Three methods will be defined on the calling object which allow to use this configurable extension:

configurables

  Returns a hash of hashes that is used to store all configurables of the object.

<name>(ext_name)

  Return the configured extension `ext_name`.

add_<name>(ext_name, data=nil, &block)

  Define an extension `ext_name` by specifying either the data as argument or by using a block.

       # File lib/kramdown/utils/configurable.rb
    27 def configurable(name)
    28   unless respond_to?(:configurables)
    29     singleton_class.send(:define_method, :configurables) do
    30       @_configurables ||= Hash.new {|h, k| h[k] = {} }
    31     end
    32   end
    33   singleton_class.send(:define_method, name) do |data|
    34     configurables[name][data]
    35   end
    36   singleton_class.send(:define_method, "add_#{name}".intern) do |data, *args, &block|
    37     configurables[name][data] = args.first || block
    38   end
    39 end
