However, I am interested in there being some structure for all entries (from sub-categories). Of course the ones I mentioned have (multiple) categories attached. This makes it difficult but not impossible.

I guess your answer is 'No breadcrumb'.

Perhaps I'll suggest an alternative.

Thanks.

@
if pagename.startswith('Category:')
supercategories = pagename.split('::')
for category in supercategories:
if category != supercategories[-1]:
print link_to(category)
else:
print bold(category)
else:
print bold(pagename)

It even says "for category pages only" in my last post. It's okay if you don't get it - just wait until it's implemented and it will become clear. In case there are real questions about the implementation from people who actually do the implementation, I'll be happy to answer them over at the bug tracker:

As described in my original post, the idea is to have these breadcrumbs for Category pages only where there is a "super-category". I don't think it's a good idea to include history in the breadcrumbs. What I want is just to have an easy way to go from a sub-category to its super-category without having to manually edit the URL or go through the home page.

Each wiki article can have multiple categories. So you can only display the breadcrumb if the user has manually clicked on that category (in their history).

Wiki home

Click on "Overview" of Language Bindings, which opens Category:LanguageBindings

Go to the middle of the page, section Subcategories and click on PySide

That's indeed a bit awkward to find. The more I think on it the more I tend to the conclusion that the wiki structure is not as easy and convenient to navigate through as it could be. I will do some research on other sides to give examples of how it may work better.
