 Lighttpd apparently sets REDIRECT_STATUS=200 for the server.error-handler-404 page. This breaks the [[plugins/404]] plugin which checks this variable for 404 before processing the URI. It also doesn't seem to set REDIRECT_URL.

 I was able to fix my server to check the REQUEST_URI for ikiwiki.cgi and to continue processing if it was not found, passing $ENV{SEVER_NAME} . $ENV{REQUEST_URI} as the first parameter to cgi_page_from_404. However, my perl is terrible and I just made it work rather than figuring out exactly what to do to get it to work on both lighttpd and apache.
 
 This is with lighttpd 1.4.19 on Debian.

+I have completely overhauled the Asciidoc plugin for ikiwiki that was created by [[Karl Mowson|http://www.mowson.org/karl/colophon/]].  The source can be downloaded from my [[Dropbox|http://dl.dropbox.com/u/11256359/asciidoc.pm]].
+
+### Features
+
+* Uses a filter hook to escape WikiLinks and Directives using Asciidoc `+++` passthrough macros, to avoid them being processed by Asciidoc. This behavior is configurable in the wiki setup file.
+* Adds a preprocessor directive 'asciidoc' which allows extra Asciidoc command-line options to be passed on a per-page basis. Each parameter name is the option name (the leading `--` will be inserted automatically), and the parameter value is the option value. Currently, only 'conf-file' and 'doctype' are allowed (or even useful).
+* Sets the page title from the first line in the Asciidoc file using a meta directive. This behavior is configurable in the wiki setup file.
+* Searches for an Asciidoc configuration file named the same as the wiki if none is specified in the setup file.
+* Asciidoc configuration files are stored in the wiki. They should be named `._conf` to avoid publishing them.
+
+### Problems
+
+* Escaping Directives is not optimal. It prevents markup from being used in Directives, and the passthrough macros have to include extra spaces to avoid having directives that return an empty string collapse to `++++++`. In addition, I had to borrow the regexps from the Ikiwiki source code; it would be nice if this were available as part of the API.
+* Handling of Asciidoc errors is suboptimal; they are simply inserted into the returned page.  This could be fixed in Perl 5.12 by using the run_forked() in IPC::Cmd.

+I have a second plugin that adds a directive 'dump', and dumps all sorts of information (env variables and template variables) about a page into the end of the page. It's cheesy, but it's available in my [[Dropbox|http://dl.dropbox.com/u/11256359/dump.pm]] as well as the Asciidoc plugin.
+
+### Issues
+* It really ought to use some kind of template instead of HTML. In fact, it ought to embed its information in template variables of some kind rather than stuffing it into the end of the page.

 OK, here's an alternative approach, closer in spirit to what was initially

+requested. I haven't tested this on a full website with the CGI yet.
 
 The idea is that in the common case, the CGI and the pages will reside on the
 same server, so they can use "semi-absolute" URLs (`/ikiwiki.cgi`, `/style.css`,
-`/bugs/done`) to refer to each other. My branch adds config options which
-could be set as follows for ikiwiki.info or any branchable.com site:
-
-* local_url: /
-* local_cgiurl: /ikiwiki.cgi
-
-Most redirects, form actions, links etc. can safely use this form rather than
-the fully-absolute URL. If not configured, these options default to the
-corresponding absolute URL, which is would also be correct for unusual sites
-where the CGI and the pages aren't on the same server.
-
-(In theory you could use things like `//static.example.com/wiki/` and
-`//dynamic.example.com/ikiwiki.cgi` to preserve choice of http/https
+`/bugs/done`) to refer to each other. Most redirects, form actions, links etc.
+can safely use this form rather than the fully-absolute URL.
+
+The initial version of the branch had config options `local_url` and
+`local_cgiurl`, but they're now automatically computed by checking
+whether `url` and `cgiurl` are on the same server with the the same URL
+scheme. In theory you could use things like `//static.example.com/wiki/`
+and `//dynamic.example.com/ikiwiki.cgi` to preserve choice of http/https
 while switching server, but I don't know how consistently browsers
-suppot that.)
+suppot that.
 
 "local" here is short for "locally valid", because these URLs are neither
 fully relative nor fully absolute, and there doesn't seem to be a good name
 for them...
+
+New API added by this branch:
+
+* `urlto(x, y, 'local')` uses `$local_url` instead of `$config{url}`
+
+* `IkiWiki::baseurl` has a new second argument which works like the
+  third argument of `urlto`
+
+* `IkiWiki::cgiurl` uses `$local_cgiurl` if passed `local_cgiurl => 1`
+
+* `IkiWiki::cgiurl` omits the trailing `?` if given no named parameters
+  except `cgiurl` and/or `local_cgiurl`
+
+Bugs:
+
+* I don't think anything except `openid` calls `cgiurl` without also
+  passing in `local_cgiurl => 1`, so perhaps that should be the default;
+  `openid` uses the `cgiurl` named parameter anyway, so there doesn't even
+  necessarily need to be a way to force absolute URLs? Any other module
+  that really needs an absolute URL could use
+  `cgiurl(cgiurl => $config{cgiurl}, ...)`,
+  although that does look a bit strange
+
+* It occurs to me that `IkiWiki::cgiurl` could probably benefit from being
+  exported? Perhaps also `IkiWiki::baseurl`?
+
+* Or, to reduce use of the unexported `baseurl` function, it might make
+  sense to give `urlto` a special case that references the root of the wiki,
+  with a trailing slash ready to append stuff: perhaps `urlto('/')`,
+  with usage like this?
+
+        do_something(baseurl => urlto('/', undef, local)`);
+        do_something_else(urlto('/').'style.css');
+        IkiWiki::redirect(urlto('/', undef, 1));
