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](http://kitenet.net/~kyle/family/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](http://kitenet.net/~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

[[tag patch]]

This is my second cut at a feature like that requested here.
It can also be found [here](http://ikidev.betacantrips.com/patches/move.patch).

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.

Hmm. Shouldn't that be done on a by-RCS basis, though? (i.e. implemented
by backends in the `rcs_move` function)

Also, how should ikiwiki react if a page is edited (say, by another user)
before it is moved? Bail, or shrug and proceed?
