[drupal-devel] Improve Drupal themability

[Stefan Nagtegaal]

All,

to improve theming of drupal I would like to introduce two new 
functions, which are theme_list() and theme_list_item()..

function theme_list($items = array(), $id) {
   if (isset($items)) {
     $output .= '<ul id="'. $id .'">';
     foreach ($items as $item) {
       $output .= theme('list_item', $item);
     }
     $output .= '</ul>';
   }
   return $output;
}

function theme_list_item($item, $class = NULL) {
   return '<li class="'. $class .'">'. $item .'</li>';
}

These two functions will help us, theme drupal. Every list is getting a 
unique id like $module-$method. For example we get:

<ul id="book navigation">
   <li class="leaf"><a href="#">...</a></li>
   <li class="leaf"><a href="#">...</a></li>
   <li class="leaf"><a href="#">...</a></li>
</ul>

With these two functions we can get all hardcoded lists (<ul><li>) out 
of drupal..
At the end, a lot of theme function will be deprecated. you can think 
about theme_status_messages(), theme_node_list().

Combining this with the modified theme_box()-approach of Ber Kessels 
(http://drupal.org/node/15332) we can theme almost anything we want and 
how we want, with less extraneous markup..

I would like to know what you guys think about this, and dicuss before 
having some major patches hitting the patch queue..



Stefan.
