24 24 # Plugins are registered using the <tt>register</tt> class method that acts as the public constructor.

26 26 # Redmine::Plugin.register :example do

28 28 # author 'John Smith'
29 29 # description 'This is an example plugin for Redmine'

34 34 # === Plugin attributes
35 35 #
36 36 # +settings+ is an optional attribute that let the plugin be configurable.
37 37 # It must be a hash with the following keys:
38 38 # * <tt>:default</tt>: default value for the plugin settings
39 39 # * <tt>:partial</tt>: path of the configuration partial view, relative to the plugin <tt>app/views</tt> directory
40 40 # Example:
41 41 # settings :default => {'foo'=>'bar'}, :partial => 'settings/settings'
42 42 # In this example, the settings partial will be found here in the plugin directory: <tt>app/views/settings/_settings.rhtml</tt>.
43 43 #
44 44 # When rendered, the plugin settings value is available as the local variable +settings+
