Well, here's my version too. It only does getctime -- using a real XML parser, instead of regexp ugliness -- and maybe recentchanges, but that may be bitrotted, or maybe I never finished it, as I only need the getctime. As for actual commits, I have previously voiced my opinion, that this should be done by the plugin generating a patch bundle, and forwarding it to darcs in some way (`darcs apply` or even email to another host, possibly moderated), instead of the hacky direct modification of a working copy. It could also be faster to getctime in a batch. Just reading in all the changes the first time they're needed, might not be a big improvement in many cases, but if we got a batch request from ikiwiki, we could keep reaing the changes until all the files in this batch request have been met. --[[tuomov]]

I merged the two versions above and made some fixes; it is recording my web edits in darcs and showing a recent changes page.
It is in a [darcs repository](http://joyful.com/darcsweb/darcsweb.cgi?r=ikiwiki-darcs), please send patches. --[[Simon_Michael]]

I have addressed the recentchanges bit, you can find my hacked up darcs.pm at .
It's got couple of FIXMEs, and a very site-specific filter for recentchanges. Not sure how to do that better though. I will eventually add web commits, probably of my own (and mention it here).

And here's yet another one, including an updated `ikiwiki-makerepo`. :)
(now a darcs repo)

I've taken all the good stuff from the above and added the missing hooks. The code hasn't seen a lot of testing, so some bugs are likely yet to surface. Also, I'm not experienced with perl and don't know where I should have used the function `possibly_foolish_untaint`.
Regarding the repository layout: There are two darcs repositories. One is the `srcdir`, the other we'll call `master`.
* HTML is generated from `srcdir`.
* CGI edits happen in `srcdir`.
* The backend pulls updates from `master` into `srcdir`, i.e. darcs commits should happen to `master`.
* `master` calls ikiwiki (through a wrapper) in its apply posthook, i.e. `master/_darcs/prefs/defaults` should look like this:
apply posthook ikiwrap
apply run-posthook
(I'm not sure, should/could it be `ikiwrap --refresh` above?)
* The backend pushes CGI edits from `srcdir` back into `master` (triggering the apply hook).
* The working copies in `srcdir` and `master` should *not* be touched by the user, only by the CGI or darcs, respectively.
> Review of this one:
>
> * Should use tab indentation.
> * `rcs_getctime` should not need to use a ctime cache (such a cache should
> also not be named `.ikiwiki.ctimes`). `rcs_getctime` is run exactly
> once per page, ever, and the data is cached in ikiwiki's index.
> * I doubt that ENV{DARCS} will be available, since the wrapper clobbers> the entire
> environment. I'd say remove that.
> * I don't understand what `darcs_info` is doing, but it seems to be
> parsing xml with a regexp?
> * Looks like `rcs_commit` needs a few improvements, as marked TODO
> * `rcs_remove` just calls "rm"? Does darcs record notice the file was removed
> and automatically commit the removal? (And why `system("rm")` and not
> `unlink`?)
> * Is the the darcs info in [[details]] still up-to-date re this version?
