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.
