module Redmine #:nodoc:

  class PluginNotFound < StandardError; end

  class PluginRequirementError < StandardError; end

  # Base class for Redmine plugins.

  # Plugins are registered using the <tt>register</tt> class method that acts as the public constructor.

  #

  #   Redmine::Plugin.register :example do

  #     name 'Example plugin'

  #     author 'John Smith'

  #     description 'This is an example plugin for Redmine'

  #     version '0.0.1'

  #     settings :default => {'foo'=>'bar'}, :partial => 'settings/settings'

  #   end

  #

  # === Plugin attributes

  #

  # +settings+ is an optional attribute that let the plugin be configurable.

  # It must be a hash with the following keys:

  # * <tt>:default</tt>: default value for the plugin settings

  # * <tt>:partial</tt>: path of the configuration partial view, relative to the plugin <tt>app/views</tt> directory

  # Example:

  #   settings :default => {'foo'=>'bar'}, :partial => 'settings/settings'

  # In this example, the settings partial will be found here in the plugin directory: <tt>app/views/settings/_settings.rhtml</tt>.

  #

  # When rendered, the plugin settings value is available as the local variable +settings+
