Revisions feature

I made some modifications in nofitications_content.module - node revisions token values:

function notifications_content_nodeapi();
[code]
case 'insert':
// Notifications just for published nodes. If we don't have any option enabled for this content type, skip the event
if (!isset($done[$node->nid]) && $node->status && empty($node->notifications_content_disable) && notifications_content_type_enabled($node->type)) {
$done[$node->nid] = TRUE;
$event = array(
'module' => 'node',
'oid' => $node->nid,
'type' => 'node',
'action' => $op,
'node' => $node,
'params' => array('nid' => $node->nid, "vid" => $node->vid),
);
if ($op == 'update') {
// If the node has been published the 'update' will become a 'insert' (first post)
// In this case the event user will be the node author instead of the current user
if (!isset($node->old_status)) {
// We try to find out previous status with the cached node.
$oldnode = node_load($node->nid);
$node->old_status = $oldnode->status;
}
if (!$node->old_status) {
// The node has gone from unpublished to published, adjust event parameters
$event['uid'] = $node->uid;
$event['action'] = 'insert';
}
// If immediate sending is active, need to reset the node cache so we don't send old versions of the node
if (variable_get('notifications_send_immediate', 0)) {
node_load(0, NULL, TRUE);
}
}
notifications_event($event);
}
break;
[/code]

function notifications_content_notifications();
[code]
case 'event load': // $arg0 is event
$event = &$arg0;
$load = array();
if ($event->type == 'node') {
if (!empty($event->params['nid']) && empty($event->objects['node'])) {
if ($node = node_load($event->params['nid'])) {
$event->objects['node'] = $node;
$event->objects['revisions'] = node_load($event->params['nid'],$event->params['vid']);
}
else { // Node not available anymore, mark event for deletion
$event->delete = TRUE;
}
}
if (!empty($event->params['cid']) && empty($event->objects['comment'])) {
if ($comment = notifications_content_comment_load($event->params['cid'])) {
$event->objects['comment'] = $comment;
}
else { // Comment not available anymore, mark event for deletion
$event->delete = TRUE;
}
}
}
break;
[/code]

function notifications_content_token_list();
[code]
if ($type == 'node' || $type == 'all') {
$tokens['node']['node-teaser'] = t('The node teaser.');
$tokens['node']['node-body'] = t('The node body.');
//$tokens['node']['node-url'] = t('The node view url for read more links.');
$tokens['node']['node-teaser-raw'] = t('Unfiltered node teaser. WARNING - raw user input.');
$tokens['node']['node-body-raw'] = t('Unfiltered node body. WARNING - raw user input.');
$tokens['node']['revision-user'] = t('User of node revision');
$tokens['node']['revision-date'] = t('Date of node revision');
}
[/code]

function notifications_content_token_values();
[code]
case "revisions":
if ($revision = $object) {
$ruser = user_load($revision->revision_uid);
$values['revision-user'] = $ruser->name;
$values['revision-date'] = format_date($revision->revision_timestamp, 'small');
return $values;
}
break;
[/code]
