What this book covers

Chapter 1, Introduction to Redmine Plugins, provides an introduction to the basic structure of a Redmine plugin as well as some preliminary initialization and configuration settings.

Chapter 2, Extending Redmine Using Hooks, dives into how Redmine core components such as internal models, views, controllers, and helpers can be extended from within our plugin through the use of the hooks system.

Chapter 3, Permissions and Security, introduces the Redmine permissions system and how our plugin can make use of this existing infrastructure. It also includes a case study on how a custom access control system can be implemented by a plugin in order to limit access to content in a more granular fashion.

Chapter 4, Attaching Files to Models, highlights how quickly Redmine's built-in file attachment components can be added to our plugin models, views, and controllers.

Chapter 5, Making Models Searchable, walks the user through how some of Redmine's core plugins can be used to allow a plugin model's content to be included within the search system. It also covers how permissions are used to limit search results, and even how the default search functionality provided through Redmine's core plugin can be overridden, allowing us to further limit results using custom logic or permissions.

Chapter 6, Interacting with the Activity Stream, introduces another core Redmine plugin that allows us to inject custom events into a project's activity stream. It also covers how activity events are defined and formatted and how activity providers are configured and registered.

Chapter 7, Managing Plugin Settings, covers the definition and initialization of plugin settings and how a generic view partial can be provided to facilitate management of these settings values. It also discusses how these setting values can be applied within our plugin's views and controllers.

Chapter 8, Testing Your Plugin, provides an introduction to writing and running unit, integration, and functional tests that tie into Redmine's infrastructure. It also provides a brief note on how to integrate a GitHub hosted Redmine plugin with the Travis CI continuous integration service.

Appendix, Releasing Your Plugin, gives some pointers to plugin authors regarding what they can do to promote the release of their newly authored plugin. This is only meant to provide a handful of suggestions and not act as a de facto guide on plugin publication.
