The header of subpages always links to its "superpage", even if it doesn't exist. I'm not sure if this is a feature or a bug, but I would certainly prefer that superpages weren't mandatory.

For example, if you are in 'example/page.html', the header will be something like 'wiki / example / page'. Now, if 'example.html' doesn't exist, you'll have a dead link for every subpage.

This is a bug, but fixing it is very tricky. Consider what would happen if example.mdwn were created: example/page.html and the rest of example/ would need to be updated to change the parentlink from a bare word to a link to the new page. Now if example.mdwn were removed again, they'd need to be updated again. So example/ depends on example. But it's even more tricky, because if example.mdwn is modified, we don't want to rebuild example/*!

ikiwiki doesn't have a way to represent this dependency and can't get one without a lot of new complex code being added.

Note that this code has now been added. In new terms, example/* has a presence dependency on example. So this bug is theoretically fixable now. --Joey

For now the best thing to do is to make sure that you always create example if you create example/foo. Which is probably a good idea anyway..

Note that this bug does not exist if the wiki is built with the "usedirs" option, since in that case, the parent link will link to a subdirectory, that will just be missing the index.html file, but still nicely usable. --Joey does not exist. Then, on, in the parentlinks line, writing links to the top-level index file. It should rather not link anywhere at all. --tschwinge

So, the bug has changed behavior a bit. Rather than a broken link, we get a link to the toplevel page. This, FWIW, is because the template now uses this for each parentlink:

<a href="<TMPL_VAR URL>"><TMPL_VAR PAGE></a>/

Best workaround is still to enable usedirs. --Joey
