Module weave

Render items in a mapping using patterns found in the children of the element.

Keyvalue recognizes the following patterns:

• header: Rendered at the start, before the first item. If multiple header patterns are provided they are rendered together in the order they were defined.
• footer: Just like the header only renderer at the end, after the last item.
• item: Rendered once for each item in the sequence. Can contain subpatterns key and value.

  If multiple item patterns are provided then the pattern is cycled in the order defined.

• divider: Rendered once between each item in the sequence. Multiple divider patterns are cycled.
• empty: Rendered instead of item and divider patterns when the sequence contains no items.

Example:

 <table nevow:render="sequence" nevow:data="peopleSeq">
   <tr nevow:pattern="header">
     <th>name</th>
     <th>email</th>
   </tr>
   <tr nevow:pattern="item" class="odd">
     <td>name goes here</td>
     <td>email goes here</td>
   </tr>
   <tr nevow:pattern="item" class="even">
     <td>name goes here</td>
     <td>email goes here</td>
   </tr>
   <tr nevow:pattern="empty">
     <td colspan="2"><em>they've all gone!</em></td>
   </tr>
 </table>

Provide alternating background colors for e.g. zebra tables.

Parameters:

• styles - Two or more CSS class names to iterate.

  Use like this:

   render_zebra = weave.zebra()
  
   <table>
     <tr nevow:render="zebra"><td>foo</td></tr>
     <tr nevow:render="zebra"><td>bar</td></tr>
     <tr nevow:render="zebra"><td>baz</td></tr>
   </table>
