ShowPath integration into Trac

[cmarschalek]

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 :)

any news on this?

[Matthew Good]

Milestone 0.9.7 is for bug fixes only. This will not be added for that release.

[cmarschalek]

Well, can you set another milestone (or close it) then? It would be nice to finally find out what you guys think about this enhancement :) Tia!

I added this patch by hand the to 0.10 trunk and it works just great.

[Christopher Lenz]

We're feature-freezing 0.10, so this isn't going in now.

[anonymous]

please don't ignore this feature. It is very useful.

[markus]

I'd like to see it too coming with 0.10…

showpath patch updated to the trunk r3717

Replying to markus:

As cmlenz said, this will not be going into 0.10. We need to lock down the feature set so we can work out some remaining bugs and push out the release.

[sid]

You should be able to do this quite easily in 0.11 using PageTemplates. See r3881 and #962 for more details.

You'll just need to add a PageTemplates/DefaultPage with the macro in it.

[Christian Boos]

See #4423, which discusses how to solve this in a generic way.

[Christian Boos]

I'll add the hierarchical path information, similar to what we have for the repository browser. Related to #4507.

[cmarschalek]

Thanks, sounds great!

[anonymous]

For 0.10.4 change:

    	prefix = Markup(page.name)

to

    	prefix = page.name

and this will work — not sure the implications, but that did the trick for me.

Also slap some css in share\trac\htdocs\css\trac.css

div.wikinav {
 position: absolute;
 top: 117px;
 left: 10px;
 color: #999;
 text-transform: lowercase;
 display: block;
}

Adjust CSS for positioning as needed.

I took the version on MacroBazaar, which wasn't quite right, fixed it up, and put it on Trac Hacks at ​th:wiki:ShowPathPlugin.

Patch against 0.11-stable showing the path of hierarchical wiki pages

[Remy Blank]

Replying to cboos:

I'll add the hierarchical path information, similar to what we have for the repository browser.

The patch above adds clickable path information to the top of hierarchical wiki pages. The path is not shown for non-hierarchical pages.

Questions:

• The style has been borrowed directly from the repository browser. It is relatively close to the style of first-level wiki titles, except for the color. Should it be made more differentiated?

• Should this functionality be made configurable?

Comments?

[cmarschalek]

The style should be a css class which can be customized when needed (imho) ;)

If you look at the patch, you'll see that it is a set of CSS classes.

"Should this functionality be made configurable? "

Did you mean the overall functionality of showing the breadcrumbs then? If so, imho, this doesn't need to be configurable (like I said before a wiki should have some default way of navigation). I'm certain though, that at least someone will not like such feature, but looking at the patch (yes, now I did;) it should be quite easy to remove…

Replying to cmarschalek:

Yes, that's what I meant. Sorry for not being clear.

Please note though that this patch doesn't implement breadcrumbs, but shows the path for pages that have a hierarchical structure (i.e. contain a '/'). Breadcrumbs are a list of the most recently visited items. There's a plugin for that: ​th:BreadCrumbsNavPlugin.

[anonymous]

Well for hierachical data the recently visited items is the path ;) Anyway this "path" is what I ment with breadcrumbs in lack of a better term…

How about letting this in into 0.11.2?
