 `rcs_commit()` uses backticks instead of `system()`, to prevent darcs' output being sent to the browser and mucking with the HTTP headers (`darcs record` has no --quiet option). And `rcs_recentchanges()` uses regexes rather than parsing darcs' XML output.

 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]]

 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. :)
+
+<http://khjk.org/~pesco/ikiwiki-darcs/>
+
+I've taken all the good stuff from the above and added the missing hooks. Some of them I haven't had a chance to test, namely `rcs_rename`, `rcs_remove`, `rcs_commit_staged`, and `rcs_diff`. 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?
