HowTo Use Hooks¶

This How-To is only relevant for plugin authors trying to extend Redmine

Redmine supports the concept of Hooks. It is an API to allow external code to extend the core Redmine functionality in a clean way. Hooks allow the plugin author to register callback functions which are executed one after another when the Redmine code reaches specific points in the code.

Additional methods to extend or replace Redmine code are:

• Using rails callbacks
• Wrapping an existing method using alias_method_chain
