function diff_entity_info_alter in Diff 7.3

Implements hook_entity_info_alter().

Although the module only provides an UI for comparing nodes, it has an extendable API for any entity, so we supply two view modes for all entities.

• diff_standard: This view mode is used to tell the module how to compare individual fields. This is used on the revisions page.

File

./diff.module, line 252

Provides functionality to show a diff between two node revisions.

Code

function diff_entity_info_alter(&$entity_info) {
  foreach (array_keys($entity_info) as $entity_type) {
    if (!empty($entity_info[$entity_type]['view modes'])) {
      $entity_info[$entity_type]['view modes'] += array(
        'diff_standard' => array(
          'label' => t('Revision comparison'),
          'custom settings' => FALSE,
        ),
      );
    }
  }
