It would be great if I could tell ikiwiki to automatically instantiate pages for each [[tag|/tags]], according to a template, especially when $tagbase is set.
Tags are mainly specific to the object to which they’re stuck. However, I often use them the other way around, too: as concepts. And sometimes I’d like to see all pages related to a given concept (“tagged with a given tag”). The only way to do this with ikiwiki is to instantiate a page for each tag and slap a map on it. This is quite tedious and I’d really love to see Ikiwiki do so by default for all tags.

I would love to see this as well. -- dato
I have create a patch to [[tag.pm|plugins/tag]] for add the option for auto create tag pages.
A new setting is used to enable or disable auto-create tag pages, tag_autocreate.
The new tag file is created during the preprocess phase.
The new tag file is then complied during the change phase.

This uses a [[template|wikitemplates]] called autotagpage.tmpl, here is my template file:
\[[!inline pages="link(<TMPL_VAR TAG>)" archive="yes"]]
A quirk I have not figured out is during the sub change, see my comments in the code.
I am not sure if that is the best way to handle it.

No, this doesn't help:
+ # This refresh/saveindex is to fix the Tags link
+ # With out this additional refresh/saveindex the tag link displays ?tag
+ IkiWiki::refresh();
+ IkiWiki::saveindex();
On the second extra pass, it doesn't notice that it has to update the "?"-link. If I run ikiwiki once more, it is updated. I don't know yet how this should be fixed, because I don't know the internals of ikiwiki well enough. Something inhibits detecting the need to update in refresh() in Render.pm; perhaps, this condition:
if (! $pagemtime{$page}) {
...
push @add, $file;
...
}
is not satisfied for the newly created tag page. I shall put debug msgs into Render.pm to find out better how it works. --Ivan Z.
