1. THE DRUPAL 8 PLUGIN SYSTEM: EXTENSIBILITY FOR ALL I am , , and .Xano @BartFeenstra http://mynameisbart.com

2. WHAT ARE PLUGINS? Swappable extensions that provide logic for a specific (set of) task(s) Uniquely identifiable Metadata Multiple instances can co-exist (reuse)

3. DRUPAL 7 PLUGINS Hook discovery (core and most contributed modules) File-based discovery (ctools) Magic hooks/callbacks/includes Some plugins are classed

4. SAY WHAT?

5. DRUPAL 8 PLUGINS Are classed. Always. Should implement interfaces. Consistent API for discovering and instantiating plugins, regardless of type.

6. NO MORE DARK MAGIC

7. JARGON, DO YOU SPEAK IT?

8. PLUGIN TYPE

9. PLUGIN (DEFINITION)

10. PLUGIN DISCOVERY

11. PLUGIN FACTORY

12. PLUGIN MANAGER (DISCOVERY + FACTORY + ...)

13. PLUGIN INSTANCE

14. PLUGIN CONFIGURATION

15. RECREATING/CLONING PLUGIN INSTANCES Using Plugin type/manager, ID, and configuration through ConfigurablePluginInterface.

16. DISCOVERY METHODS Annotated class discovery (mostly different logic) YAML discovery (mostly reused logic) Static discovery (testing) Hook discovery (deprecated)

17. ANNOTATED CLASS DISCOVERY

18. YAML DISCOVERY system.admin: title: Administration route_name: system.admin weight: 9 menu_name: admin system.admin_content: title: Content description: 'Find and manage content.' route_name: system.admin_content parent: system.admin weight: -10 system.admin_structure: route_name: system.admin_structure parent: system.admin description: 'Administer blocks, content types, menus, etc.' title: Structure weight: -8

20. DERIVATIVES One base plugin definition can be dynamically expanded into multiple derivative plugin definitions.

21. THERE'S A MODULE FOR THAT http://drupal.org/project/plugin

22. PLUGIN TYPE DISCOVERY

23. ADMINISTRATIVE OVERVIEW

24. CONFIGURATION SCHEMAS plugin.plugin_configuration.*.*

25. TYPED PLUGIN DEFINITION API Now: PluginDefinitionMapperInterface Future: PluginDefinitionInterface

26. PLUGIN SELECTORS

27. FIELD TYPES/WIDGETS/FORMATTER S

28. CONCLUSION EXTENDING DRUPAL HAS NEVER BEEN EASIER.
