Internal links
--------------
+### Links targets
+
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
`destpage`'s version written in the current page's language, if
* `foo/destpage/index.LL.html` if `usedirs` is enabled
* `foo/destpage.LL.html` if `usedirs` is disabled
-### Link to negotiated language
+#### Link to negotiated language
If `po_link_to` is set to `negotiated`, `\[[page]]` links to the
negotiated preferred language, *i.e.* `foo/page/`.
* if the web server does not support Content Negotiation, setting
`po_link_to` to `negotiated` will produce a unusable website.

Server support
==============
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">
- <div id="percenttranslated">
- <TMPL_VAR NAME="PERCENTTRANSLATED">
- </div>
- </TMPL_IF>
+completeness, expressed in percent, on "slave" pages. It is used by
+the default `templates/page.tmpl`.

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

-Robustness tests
-----------------
-
-### Enabling/disabling the plugin
-
-* 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**
-
-### Changing the plugin config
-
-* 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)
-
-### Creating/deleting/renaming pages
-
-All cases of master/slave page creation/deletion/rename, both via RCS
-and via CGI, have been tested.
-
-### Misc
-
-* 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**

-Misc. bugs
+[[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 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]]
+
+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]]
+
+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?
