+[Darcs](http://darcs.new) is a distributed revison control
+system. Ikiwiki supports storing a wiki in a
+Darcs repository.
+
+An Ikiwiki wrapper is run by the `posthook` to update a wiki whenever commits
+or remote pushes come in. When running as a [[cgi]] with Darcs, ikiwiki
+automatically commits edited pages, and uses the Darcs history to generate the
+[[RecentChanges]] page.
+
+Example for a `_darcs/prefs/defaults` file in `$SRCDIR`:
+
+ apply posthook /path/to/repository/_darcs/ikiwiki-wrapper
+ apply run-posthook

-## [darcs](http://darcs.net/) (not yet included)
+## [[darcs]]
-Support for using darcs as a backend is being worked on by [Thomas
-Schwinge](mailto:tschwinge@gnu.org), although development is on hold curretly.
-There is a patch in [[todo/darcs]].
+Regarding the repository layout: There are two darcs repositories. One is the `srcdir`, the other we'll call `master`.
-### How will it work internally?
+* 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:
-``Master'' repository R1.
-
-RCS commits from the outside are installed into R1.
-
-HTML is generated from R1. HTML is automatically generated (by using a
-``post-hook'') each time a new change is installed into R1. It follows
-that rcs_update() is not needed.
-
-There is a working copy of R1: R2.
-
-CGI operates on R2. rcs_commit() will push from R2 to R1.
-
-You browse the wiki on R1 and web-edit it on R2. This means for example
-that R2 needs to be updated from R1 if you are going to web-edit a page,
-as the user otherwise might be irritated otherwise...
-
-How do changes get from R1 to R2? Currently only internally in
-rcs\_commit(). Is rcs\_prepedit() suitable?
-
-It follows that the HTML rendering and the CGI handling can be completely
-separated parts in ikiwiki.
-
-What repository should [[RecentChanges]] and History work on? R1?
-
-#### Rationale for doing it differently than in the Subversion case
-
-darcs is a distributed RCS, which means that every checkout of a
-repository is equal to the repository it was checked-out from. There is
-no forced hierarchy.
-
-R1 is nevertheless called the master repository. It's used for
-collecting all the changes and publishing them: on the one hand via the
-rendered HTML and on the other via the standard darcs RCS interface.
-
-R2, the repository the CGI operates on, is just a checkout of R1 and
-doesn't really differ from the other checkouts that people will branch
-off from R1.
-
-(To be continued.)
-
-#### Another possible approach
-
-Here's what I (tuomov) think, would be a “cleaner” approach:
-
- 1. Upon starting to edit, Ikiwiki gets a copy of the page, and `darcs changes --context`.
- This context _and_ the present version of the page are stored in as the “version” of the
- page in a hidden control of the HTML.
- Thus the HTML includes all that is needed to generate a patch wrt. to the state of the
- repository at the time the edit was started. This is of course all that darcs needs.
- 2. Once the user is done with editing, _Ikiwiki generates a patch bundle_ for darcs.
- This should be easy with existing `Text::Diff` or somesuch modules, as the Web edits
- only concern single files. The reason why the old version of the page is stored in
- the HTML (possibly compressed) is that the diff can be generated.
- 3. Now this patch bundle is applied with `darcs apply`, or sent by email for moderation…
- there are many possibilities.
-
-This approach avoids some of the problems of concurrent edits that the previous one may have,
-although there may be conflicts, which may or may not propagate to the displayed web page.
-(Unfortunately there is not an option to `darcs apply` to generate some sort of ‘confliction resolution
-bundle’.) Also, only one repository is needed, as it is never directly modified
-by Ikiwiki.
-
-This approach might be applicable to other distributed VCSs as well, although they're not as oriented
-towards transmitting changes with standalone patch bundles (often by email) as darcs is.
-

-This is my ([bma](bma@bmalee.eu)) darcs.pm - it's messy (my Perl isn't up to much) but seems to work. It uses just one repo, like the mercurial plugin (unlike the above version, which AIUI uses two).
-
-`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]]

-I merged the two versions above and made some fixes; it is recording my web edits in darcs and showing a recent changes page.

-
-> I'd like to see at least the following fixed before I commit this: --[[Joey]]
-> * Running `darcs record $filename` in backticks is not good (security)
-> The thing to do is to open stdout to /dev/null before execing darcs.
-> * Get `rcs_recentchanges_xml` working, parsing xml with regexps does
-> not seem like a maintenance win.
-> * `rcs_notify` should be removed, it's no longer used.
-> * Some form of conflict handling. Using darcs to attempt to merge
-> the changes is I gusss optional (although every other rcs backend,
-> including svn manages to do this), but it needs to at *least* detect
-> conflicts and return a page with conflict markers for the user to fix
-> the conflict.
-
-I have addressed the recentchanges bit, you can find my hacked up darcs.pm at <http://web.mornfall.net/stuff/web-root/IkiWiki/Rcs/darcs.pm>.
-
-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`. :)
-
<http://khjk.org/~pesco/ikiwiki-darcs/> (now a darcs repo)
-> Note that there's a 'darcs' branch in git that I'm keeping a copy of your
-> code in. Just in case. :-)
-
-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.

+I've finally merged this into ikiwiki master. The plugin looks quite
+complete, with only the new `rcs_receive` hook missing, and I
+hope it works as good as it looks. :) If anyone wants to work on improving
+it, there are some TODOs as mentioned above that could still be improved.
