Internal links

The `po_link_to` option in `ikiwiki.setup` is used to decide how
internal links should be generated, depending on web server features
and site-specific preferences.
-### Default linking behavior
+#### Default linking behavior
If `po_link_to` is unset, or set to `default`, ikiwiki's default
linking behavior is preserved: `\[[destpage]]` links to the master
language's page.
-### Link to current language
+#### Link to current language
If `po_link_to` is set to `current`, `\[[destpage]]` links to the

The `OTHERLANGUAGES` loop provides ways to display other languages'
versions of the same page, and the translations' status.
-One typically adds the following code to `templates/page.tmpl`:
-
- <TMPL_IF NAME="OTHERLANGUAGES">
- <div id="otherlanguages">
- <ul>
- <TMPL_LOOP NAME="OTHERLANGUAGES">
- <li>
- <a href="<TMPL_VAR NAME="URL">"><TMPL_VAR NAME="LANGUAGE"></a>
- <TMPL_UNLESS NAME="MASTER">
- (<TMPL_VAR NAME="PERCENT"> %)
- </TMPL_UNLESS>
- </li>
- </TMPL_LOOP>
- </ul>
- </div>
- </TMPL_IF>
-
-The following variables are available inside the loop (for every page in):
+An example of its use can be found in the default
+`templates/page.tmpl`. In case you want to customize it, the following
+variables are available inside the loop (for every page in):
* `URL` - url to the page
* `CODE` - two-letters language code
### Display the current translation status
The `PERCENTTRANSLATED` variable is set to the translation
-completeness, expressed in percent, on "slave" pages.
-
-One can use it this way:
-
- <TMPL_IF NAME="ISTRANSLATION">

Better links

-### Page title in links
-
-Using the fix to
+Once the fix to
[[bugs/pagetitle_function_does_not_respect_meta_titles]] from
-[[intrigeri]]'s `meta` branch, the generated links' text is based on
-the page titles set with the [[meta|plugins/meta]] plugin. This has to
-be merged into ikiwiki upstream, though.
+[[intrigeri]]'s `meta` branch is merged into ikiwiki upstream, the
+generated links' text will be optionally based on the page titles set
+with the [[meta|plugins/meta]] plugin, and will thus be translatable.
+It will also allow displaying the translation status in links to slave
+pages. Both were implemented, and reverted in commit
+ea753782b222bf4ba2fb4683b6363afdd9055b64, which should be reverted
+once [[intrigeri]]'s `meta` branch is merged.
+
+An integration branch, called `meta-po`, merges [[intrigeri]]'s `po`
+and `meta` branches, and thus has this additional features.
+
+Language display order
+----------------------
+
+Jonas pointed out that one might want to control the order that links to
+other languages are listed, for various reasons. Currently, there is no
+order, as `po_slave_languages` is a hash. It would need to be converted
+to an array to support this. (If twere done, twere best done quickly.)
+--[[Joey]]
+
+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
+--------------------------------
-Robustness tests
-----------------
+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.
-### Enabling/disabling the plugin
+That's really confusing, especially as clicking such a link
+brings up an edit form to create a new, english page.
-* enabling the plugin with `po_translatable_pages` set to blacklist: **OK**
-* enabling the plugin with `po_translatable_pages` set to whitelist: **OK**
-* enabling the plugin without `po_translatable_pages` set: **OK**
-* disabling the plugin: **OK**
+This is with po_link_to=current or negotiated. With default, it doesn't
+happen..
-### Changing the plugin config
+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]]
-* adding existing pages to `po_translatable_pages`: **OK**
-* removing existing pages from `po_translatable_pages`: **OK**
-* adding a language to `po_slave_languages`: **OK**
-* removing a language from `po_slave_languages`: **OK**
-* changing `po_master_language`: **OK**
-* replacing `po_master_language` with a language previously part of
- `po_slave_languages`: needs two rebuilds, but **OK** (this is quite
- a perverse test actually)
+Double commits of po files
+--------------------------
-### Creating/deleting/renaming pages
+When adding a new english page, the po files are created, committed,
+and then committed again. The second commit makes this change:
-All cases of master/slave page creation/deletion/rename, both via RCS
-and via CGI, have been tested.
+ -"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"
-### Misc
+Same thing happens when a change to an existing page triggers a po file
+update. --[[Joey]]
-* general test with `usedirs` disabled: **OK**
-* general test with `indexpages` enabled: **not OK**
-* general test with `po_link_to=default` with `userdirs` enabled: **OK**
-* general test with `po_link_to=default` with `userdirs` disabled: **OK**
+Ugly messages with empty files
+------------------------------
+
+If there are empty .mdwn files, the po plugin displays some ugly messages.
+
+Translation of directives
+-------------------------
-Misc. bugs
-----------
+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.
+
+2 test suite failures
+--------------------
+
+t/po is currently failing tests 57 and 59 (and I would like to release
+soon..) --[[Joey]]
+
+> They are failing because of commit cdc3576c8d1e (po: do not inject
+> custom bestlink function when `po_link_to` eq `default`). The test
