I thought I'd draw attention to a desire of mine for ikiwiki. I'm no power-user, and mostly I do fairly simple stuff with my wiki.
However, I would like the ability (now) to rename/move/delete pages. As part of having a genealogy wiki, I've put name and dates of birth/death as part of the title of each article (so to avoid cases where people have the same name, but are children/cousins/etc of others with that name). However, some of this information changes. For instance, I didn't know a date of death and now I do, or I had it wrong originally, or it turns out someone is still alive I didn't know about. All of these cases leave me with bad article titles.
So, I can go ahead and move the file to a new page with the correct info, orphan that page, provide a link for the new page if desired, and otherwise ignore that page. But then, it clutters up the wiki and serves no useful purpose.
Anyway to consider implementing rename/move/delete ? I certainly lack the skills to appreciate what this would entail, but feel free to comment if it appears impossible, and then I'll go back to the aforementioned workaround. I would prefer simple rename, however.
Thanks again to Joey for putting ikiwiki together. I love the program.

The MediaWiki moving/renaming mechanism is pretty nice. It's easy to get a list of pages that point to the current page. When renaming a page it sticks a forwarding page in the original place. The larger the size of the wiki the more important organization tools become.
I see the need for:
- a new type of file to represent a forwarding page
- a rename tool that can
- move the existing page to the new name
- optionally drop a forwarding page
- optionally rewrite incoming links to the new location

This could be implemented through the use of an HTTP redirect to the
new page, but this has the downside that people may not know they're being
redirected.
This could also be implemented using a combination of raw inline and meta
to change the title (add a "redirected from etc." page. This could be done
with a plugin. A redirect page would be [[redirect page="newpage"]].
But then if you click "edit" on this redirect page, you won't be able
to edit the new page, only the call to redirect.

[[tag patch]]
This is my second cut at a feature like that requested here.
It can also be found here.
A few shortcomings exist:
- No precautions whatsoever are made to protect against race conditions or failures
in the rcs_move function. I didn't even do the
cgi_editpage thing where I hold
the lock and render afterwards (mostly because the copy I was editing was not
up-to-date enough to have that code). Although FAILED_SAVE is in movepage.tmpl,
no code activates it yet.
- Some code is duplicated between cgi_movepage and cgi_editpage, as well
as rcs_commit and rcs_move.
- The user interface is pretty lame. I couldn't figure out a good way to let
the user specify which directory to move things to without implementing a
FileChooser thing.
- No redirect pages like those mentioned on [[todo/Moving_Pages]] exist yet,
so none are created.
- I added a Move link to page.tmpl but it may belong better someplace else --
maybe editpage.tmpl? Not sure.
- from is redundant with page so far -- but since the Move links could someday
come from someplace other than the page itself I kept it around.
- If I move foo.mdwn to bar.mdwn, foo/* should move too, probably.
Looks like a good start, although I agree about many of the points above,
and also feel that something needs to be done about rcses that don't
implement a move operation -- falling back to an add and delete.
--[[Joey]]
Hmm. Shouldn't that be done on a by-RCS basis, though? (i.e. implemented
by backends in the rcs_move function)
Probably, yes, but maybe there's a way to avoid duplicating code for that
in several of them.
Also, how should ikiwiki react if a page is edited (say, by another user)
before it is moved? Bail, or shrug and proceed?
The important thing is to keep in mind that the page could be edited,
moved, deleted, etc in between the user starting the move and the move
happening. So, the code really needs to deal with all of these cases in
some way. It seems fine to me to go ahead with the move even if the page
was edited. If the page was deleted or moved, it seems reasonable to exit
with an error.
