abstract class CKEditorPluginBase extends PluginBase implements CKEditorPluginInterface, CKEditorPluginButtonsInterface (View source)

Defines a base CKEditor plugin implementation.

No other CKEditor plugins can be internal, unless a different CKEditor build than the one provided by Drupal core is used. Most CKEditor plugins don't need to provide additional settings forms.

This base class assumes that your plugin has buttons that you want to be enabled through the toolbar builder UI. It is still possible to also implement the CKEditorPluginContextualInterface (for contextual enabling) and CKEditorPluginConfigurableInterface interfaces (for configuring plugin settings).

NOTE: the Drupal plugin ID should correspond to the CKEditor plugin name.
