Add fields for node and comment links (links variable elements)

Hi:

Links variable (the one that includes the standard "read more", number of comments, "add new comment", etc) is generated by drupal core in node.module (read more) and comment.module (comments links).

The problem is that drupal core only knows about full and teaser view modes so the links "read more" and comment number only are shown in teaser view mode. If you, like me, have a teaser extended (teas_ext) view mode, and you want to include this links, there's no easy way to do it.

AFAIK the only way to control what to show, what to hide or what to modify is via hook or theme.

I've needed to create a hook_node_view_alter to show this links in my teas_ext view mode (and to customize them in the way I wanted). I think it would be very useful if DS provides a comment number field, add comment field, new comments field in the same way it provides a read more field by now.

Thanks.

I post the code I've used to customize my site just in case someone need it:

/**
* Implements hook_node_view_alter().
*/
function bwaslala_ui_node_view_alter(&$build) {
  $node=$build['#node'];
  $view_mode=$build['#view_mode'];
  $links=array();
  // Add links for teas_ext view mode (extracted from node.module and comment.module
  if ($view_mode == 'teas_ext') {
    // Read more for teas ext
    $node_title_stripped = strip_tags($node->title);
    $links['node-readmore'] = array(
      'title' => t('Read more<span class="element-invisible"> about @title</span>', array('@title' => $node_title_stripped)),
      'href' => 'node/' . $node->nid,
      'html' => TRUE,
      'attributes' => array('rel' => 'tag', 'title' => $node_title_stripped),
    );
    // Assign links
    $build['links']['node']['#links']=$links;
    // Comments links for teas ext
    $links=array();
    // Teaser view: display the number of comments that have been posted,
    // or a link to add new comments if the user has permission, the node
    // is open to new comments, and there currently are none.
    if (user_access('access comments')) {
      if (!empty($node->comment_count)) {
        $links['comment-comments'] = array(
          'title' => format_plural($node->comment_count, '1 comment', '@count comments'),
          'href' => "node/$node->nid",
          'attributes' => array('title' => t('Jump to the first comment of this posting.')),
          'fragment' => 'comments',
          'html' => TRUE,
        );
      }
    }
    if ($node->comment == COMMENT_NODE_OPEN) {
      if (user_access('post comments')) {
        $links['comment-add'] = array(
          'title' => t('Add new comment'),
          'href' => "comment/reply/$node->nid",
          'attributes' => array('title' => t('Add a new comment to this page.')),
          'fragment' => 'comment-form',
        );
      }
      else {
        $links['comment_forbidden'] = array(
          'title' => theme('comment_post_forbidden', array('node' => $node)),
          'html' => TRUE,
        );
      }
    }
    // Assign links
    $build['links']['comment']['#links']=$links;
  }
  // I only want add new comment link if there is no comment yet (this is applicable to teaser and teas_ext view modes)
  if (isset($build['links']['comment']['#links']['comment-comments'],$build['links']['comment']['#links']['comment-add'])) {
    unset($build['links']['comment']['#links']['comment-add']);
  }
  // I don't want new comments link (too much noise)
  if (isset($build['links']['comment']['#links']['comment-new-comments'])) {
    unset($build['links']['comment']['#links']['comment-new-comments']);
  }
  // Change read more with see more (useful to blog and gallery)
  if (isset($build['links']['node']['#links']['node-readmore'])) {
    $build['links']['node']['#links']['node-readmore']['title']=t('See more<span class="element-invisible"> about @title</span>', array('@title' => $node_title_stripped));
  }
