 Priority:  low          |   Milestone:                
Component:  wiki         |     Version:  0.9.4         
 Severity:  trivial      |    Keywords:  showpath, wiki
-------------------------+--------------------------------------------------
 I'd like to see bread-crumb-navigation for the wiki.

 I adapted the ShowPath Trac hack (http://trac-
 hacks.org/wiki/TracShowPathPatch) to 0.9.3. As I'm not very capable with
 Python, instead of a diff, here's what needs to be changed:

 == Python Source ==

 The following code needs to be added to "wiki/web_ui.py":


 {{{
         prefix = Markup(page.name)
         heirarchy = prefix.split('/')

         if len(heirarchy) > 1 or heirarchy[0] != 'WikiStart':
             req.hdf.setValue('wiki.page_parent.node_count', '%s' %
 len(heirarchy))
             for i in range(len(heirarchy)):
                 req.hdf.setValue('wiki.page_parent.node.%d' % i,
 heirarchy[i])
 }}}

 Inbetween
 {{{
        req.hdf['wiki.action'] = action
        req.hdf['wiki.page_name'] = page.name
        req.hdf['wiki.current_href'] = self.env.href.wiki(page.name)
 }}}

 and
 {{{
         return 'wiki.cs', None
 }}}
 The linenumber in 0.9.3, for the text above, is 120...


 == CSS ==

 The wiki template (wiki.cs) hast to be changed too:

 This line
 {{{
    <li><a href="<?cs var:trac.href.wiki ?>">Start Page</a></li>
 }}}
 has to be replaced with this
 {{{
  <div class="wikinav">
    >> <a href="<?cs var:$trac.href.wiki ?>">Start Page</a>
    <?cs set:node_href = trac.href.wiki ?><?cs set:node_max =
 wiki.page_parent.node_count - 1 ?>
    <?cs each:node = wiki.page_parent.node ?>
    <?cs set:node_href = node_href + '/' + node ?> > <?cs if:node_max ==
 name(node) ?><?cs var:node ?>
    <?cs else ?><a href="<?cs var:node_href ?>"><?cs var:node ?></a><?cs
 /if ?><?cs /each ?>
  </div>
 }}}
 The wikinav class has to be defined in the default css too.

 I hope this simple change can be integrated into trac :)
