+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 theyâre stuck. However, I often use them the other way around, too: as concepts. And sometimes Iâd like to see all pages related to a given concept (âtagged with a given tagâ). 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 Iâd really love to see Ikiwiki do so by default for all tags.

+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.

+
+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.
