Using Apache `mod_negotiation` makes it really easy to have Apache
serve any page in the client's preferred language, if available.
-This is the default Debian Apache configuration.

+Add 'Options MultiViews' to the wiki directory's configuration in Apache.
When `usedirs` is enabled, one has to set `DirectoryIndex index` for
the wiki context.
language code) for the wiki context can help to ensure
`bla/page/index.en.html` is served as `Content-Language: LL`.
+For details, see [Apache's documentation](http://httpd.apache.org/docs/2.2/content-negotiation.html).

lighttpd
--------
-lighttpd unfortunately does not support content negotiation.
+Recent versions of lighttpd should be able to use
+`$HTTP["language"]` to configure the translatted pages to be served.
-**FIXME**: does `mod_magnet` provide the functionality needed to
- emulate this?
+See [Lighttpd Issue](http://redmine.lighttpd.net/issues/show/1119)
+TODO: Example
Usage
=====
once [[intrigeri]]'s `meta` branch is merged.
An integration branch, called `meta-po`, merges [[intrigeri]]'s `po`
-and `meta` branches, and thus has thise additional features.

-Self links
-----------
-
-If a page contains a WikiLink to itself, ikiwiki does not normally
-turn that into a hyperlink. However, if a translated page contains a
-WikiLink to itself, a hyperlink is inserted, at least with the default
-`po_link_to` the link points to the English version of the page. Is there a
-good reason for that to be done? --[[Joey]]
+and `meta` branches, and thus has this additional features.
Language display order
----------------------
to an array to support this. (If twere done, twere best done quickly.)
--[[Joey]]
-Duplicate %links ?
-------------------
+> Done in my po branch, preserving backward compatibility. Please
+> review :) --[[intrigeri]]
+
+Pagespecs
+---------
+
+I was suprised that, when using the map directive, a pagespec of "*"
+listed all the translated pages as well as regular pages. That can
+make a big difference to an existing wiki when po is turned on,
+and seems generally not wanted.
+(OTOH, you do want to match translated pages by
+default when locking pages.) --[[Joey]]
+
+Edit links on untranslated pages
+--------------------------------
+
+If a page is not translated yet, the "translated" version of it
+displays wikilinks to other, existing (but not yet translated?)
+pages as edit links, as if those pages do not exist.
-I notice code in the scan hook that seems to assume
-that %links will accumulate duplicate links for a page.
-That used to be so, but the bug was fixed. Does this mean
-that po might be replacing the only link on a page, in error?
+That's really confusing, especially as clicking such a link
+brings up an edit form to create a new, english page.
+
+This is with po_link_to=current or negotiated. With default, it doesn't
+happen..
+
+Also, this may only happen if the page being linked to is coming from an
+underlay, and the underlays lack translation to a given language.
--[[Joey]]
-Bug when editing underlay file
+> Any simple testcase to reproduce it, please? I've never seen this
+> happen yet. --[[intrigeri]]
+
+>> Sure, go here <http://l10n.ikiwiki.info/smiley/smileys/index.sv.html>
+>> (Currently 0% translateed) and see the 'WikiLink' link at the bottom,
+>> which goes to <http://l10n.ikiwiki.info/ikiwiki.cgi?page=ikiwiki/wikilink&from=smiley/smileys&do=create>
+>> Compare with eg, the 100% translated Dansk version, where
+>> the WikiLink link links to the English WikiLink page. --[[Joey]]
+
+Double commits of po files
+--------------------------
+
+When adding a new english page, the po files are created, committed,
+and then committed again. The second commit makes this change:
+
+ -"Content-Type: text/plain; charset=utf-8\n"
+ -"Content-Transfer-Encoding: ENCODING"
+ +"Content-Type: text/plain; charset=UTF-8\n"
+ +"Content-Transfer-Encoding: ENCODING\n"
+
+Same thing happens when a change to an existing page triggers a po file
+update. --[[Joey]]
+
+> * The s/utf-8/UTF-8 part is fixed in my po branch.
+> * The ENCODING\n part is due to an inconsistency in po4a, which
+> I've just send a patch for. --[[intrigeri]]
+
+Ugly messages with empty files
------------------------------
-While I've gotten translated underlays working, there is a bug
-if the wiki is currently using a page from the underlay, and the master
-language version is edited. This causes the edited page to be saved
-to srcdir.. and all the translations get set to 0% and their
-po files have the translated strings "emptied". What's really going on
-is that these are entirely new po files not based on the old ones
-in the basewiki, and thus lacking translations. --[[Joey]]
+If there are empty .mdwn files, the po plugin displays some ugly messages.
+
+> This is due to a bug in po4a (not checking definedness of a
+> variable). One-liner patch sent. --[[intrigeri]]
+
+Translation of directives
+-------------------------
+
+If a translated page contains a directive, it may expand to some english
+text, or text in whatever single language ikiwiki is configured to "speak".
+
+Maybe there could be a way to switch ikiwiki to speaking another language
+when building a non-english page? Then the directives would get translated.
+
+(We also will need this in order to use translated templates, when they are
+available.)
