+ * Provide diff functions for the node module.

+
+/**
+ * Implements hook_entity_diff().
+ *
+ * This function compares core node properties. This is currently limited to:
+ *   - title: The title of the node.
+ *
+ * @param object $old_node
+ *   The older node revision.
+ * @param object $new_node
+ *   The newer node revision.
+ * @param array $context
+ *   An associative array containing:
+ *   - entity_type: The entity type; e.g., 'node' or 'user'.
+ *   - old_entity: The older entity.
+ *   - new_entity: The newer entity.
+ *   - view_mode: The view mode to use. Defaults to FALSE. If no view mode is
+ *                given, the recommended fallback view mode is 'default'.
+ *   - states: An array of view states. These could be one of:
+ *     - raw: The raw value of the diff, the classic 7.x-2.x view.
+ *     - rendered: The rendered HTML as determined by the view mode. Only
+ *                 return markup for this state if the value is normally shown
+ *                 by this view mode. The user will most likely be able to see
+ *                 the raw or raw_plain state, so this is optional.
+ *
+ *                 The rendering state is a work in progress.
+ *
+ *     Conditionally, you can get these states, but setting these will override
+ *     the user selectable markdown method.
+ *
+ *     - raw_plain: As raw, but text should be markdowned.
+ *     - rendered_plain: As rendered, but text should be markdowned.
+ *
+ * @return array
+ *   An associative array of values keyed by the entity property.
+ *
+ *   This is effectively an unnested Form API-like structure.
+ *
+ *   States are returned as follows:
+ *
+ *   $results['line'] = array(
+ *     '#name' => t('Line'),
+ *     '#states' => array(
+ *       'raw' => array(
+ *         '#old' => '<p class="line">This was the old line number [tag].</p>',
+ *         '#new' => '<p class="line">This is the new line [tag].</p>',
+ *       ),
+ *       'rendered' => array(
+ *         '#old' => '<p class="line">This was the old line number <span class="line-number">57</span>.</p>',
+ *         '#new' => '<p class="line">This is the new line <span class="line-number">57</span>.</p>',
+ *       ),
+ *     ),
+ *   );
+ *
+ *   For backwards compatability, no changes are required to support states,
+ *   but it is recommended to provide a better UI for end users.
+ *
+ *   For example, the following example is equivalent to returning the raw
+ *   state from the example above.
+ *
+ *   $results['line'] = array(
+ *     '#name' => t('Line'),
+ *     '#old' => '<p class="line">This was the old line number [tag].</p>',
+ *     '#new' => '<p class="line">This is the new line [tag].</p>',
+ *   );
