lighttpd
--------
-lighttpd unfortunately does not support content negotiation.
+Recent versions of lighttpd should be able to use
+`$HTTP["language"]` to configure the translated 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)

Markup languages support
------------------------
-[[Markdown|mdwn]] is well supported. Some other markup languages supported
-by ikiwiki mostly work, but some pieces of syntax are not rendered
-correctly on the slave pages:

An integration branch, called `meta-po`, merges [[intrigeri]]'s `po`
and `meta` branches, and thus has this 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]]
-
-> The commit 0113c69d4fb in my po branch might fix this. --[[intrigeri]]
-
->> It may fix it in passing, but shouldn't it also be fixed for the other
->> `po_link_to` styles? (Also, if `mybestlink` is going to always
->> just return `bestlink` in this case, there seems no reason to inject
->> it.) --[[Joey]]
-
Language display order
----------------------
to an array to support this. (If twere done, twere best done quickly.)
--[[Joey]]
-Duplicate %links ?
-------------------
-
-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?
---[[Joey]]
-
-> It would replace it. The only problematic case is when another
-> plugin has its own reasons, in its `scan` hook, to add a page
-> that is already there to `$links{$page}`. This other plugin's
-> effect might then be changed by po's `scan` hook... which could
-> be either good (better overall l10n) or bad (break the other
-> plugin's goal). --[[intrigeri]]
-
->> Right.. well, the cases where links are added is very small.
->> Grepping for `add_link`, it's just done by link, camelcase, meta, and
->> tag. All of these are supposed to work just link regular links
->> so I'd think that is ok. We could probably remove the currently scary
->> comment about only wanting to change the first link. --[[Joey]]
-
->>> Commit 3c2bffe21b91684 in my po branch does this. --[[intrigeri]]
-
-Name of toplevel index page
----------------------------
-
-Normally at the top index page of a wiki, you see the wiki name at
-the top. However, at the top *translated* index page, you see something
-like "index.da". --[[Joey]]
-
-> I suggest changing `Render.pm`, line 115, to replace the `$page eq 'index'`
-> test with a predicate call such as isindexpage($page). Such a predicate
-> function could then be overriden by the po plugin. --[[intrigeri]]
-
->> Could do that, but if you have such a function it's natural to want to
->> use it elsewhere. Not clear to me it would make sense for po to override
->> such a function if it were used in some of the other places that compare

->>
->> The other option would be for po to override the template setting.

-
->>> Great idea. Commit 6c0f9c691c3df3a in my po branch does it. --[[intrigeri]]
+> Done in my po branch, preserving backward compatibility. Please

Pagespecs

Double commits of po files
--------------------------
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]]
+
+New pages not translatable
+--------------------------
+
+Today I added a new English page to l10n.ikiwiki.info. When I saved,
+the page did not have the translation links at the top. I waited until
+the po plugin had, in the background, created the po files, and refreshed;
+still did not see the translation links. Only when I touched the page
+source and refreshed did it finally add the translation links.
+I can reproduce this bug in a test site. --[[Joey]]
+
Ugly messages with empty files
------------------------------
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
-------------------------
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.)
