It depends on the Perl `Locale::Po4a::Po` library (`apt-get install po4a`).

+denial-of-service attacks before version 0.35.

`po_master_language` is used to set the "master" language in
`ikiwiki.setup`, such as:
- po_master_language => { 'code' => 'en', 'name' => 'English' }
+ po_master_language: en|English
`po_slave_languages` is used to set the list of supported "slave"
languages, such as:
- po_slave_languages => { 'fr' => 'Français',
- 'es' => 'Castellano',
- 'de' => 'Deutsch',
- }
+ po_slave_languages:

Decide which pages are translatable
-----------------------------------
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
==============
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.
-When `usedirs` is enabled, one has to set `DirectoryIndex index` for
-the wiki context.
+Add 'Options MultiViews' to the wiki directory's configuration in Apache.
+
+When `usedirs` is enabled, you should also set `DirectoryIndex index`.
+
+These settings are also recommended, in order to avoid serving up rss files
+as index pages:
-Setting `DefaultLanguage LL` (replace `LL` with your default MIME
-language code) for the wiki context can help to ensure
-`bla/page/index.en.html` is served as `Content-Language: LL`.
+ AddType application/rss+xml;qs=0.8 .rss
+ AddType application/atom+xml;qs=0.8 .atom
+
+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 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)
+TODO: Example
Usage
=====
The `ISTRANSLATION` and `ISTRANSLATABLE` variables can be used to
display things only on translatable or translation pages.
+The `LANG_CODE` and `LANG_NAME` variables can respectively be used to
+display the current page's language code and pretty name.
+
### Display page's versions in other languages
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`.

Likewise, "slave" pages are not supposed to have sub-pages;
-[[WikiLinks|wikilink]] that appear on a "slave" page therefore link to
+[[WikiLinks|ikiwiki/wikilink]] that appear on a "slave" page therefore link to
the master page's sub-pages.
Translating
Markup languages support
------------------------
-Markdown 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:
+[[Markdown|mdwn]] and [[html]] are well supported. Some other markup
+languages supported by ikiwiki mostly work, but some pieces of syntax
+are not rendered correctly on the slave pages:
* [[reStructuredText|rst]]: anonymous hyperlinks and internal
cross-references
* [[wikitext]]: conversion of newlines to paragraphs
* [[creole]]: verbatim text is wrapped, tables are broken
-* [[html]] and LaTeX: not supported yet; the dedicated po4a modules
- could be used to support them, but they would need a security audit
+* LaTeX: not supported yet; the dedicated po4a module
+ could be used to support it, but it would need a security audit
* other markup languages have not been tested.
+Renaming a page
+---------------
+
+A translatable page may be renamed using the web interface and the
+[[rename plugin|plugins/rename]], or using the VCS directly; in
+the latter case, *both* the "master" page and every corresponding
+`.po` file must be renamed in the same commit.
+
Security
========
-[[./security]] contains a detailed security analysis of this plugin
+[[po/discussion]] contains a detailed security analysis of this plugin
and its dependencies.
When using po4a older than 0.35, it is recommended to uninstall
`Text::WrapI18N` (Debian package `libtext-wrapi18n-perl`), in order to
avoid a potential denial of service.

-### Page title in links
-
-Using 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

-Maybe write separate documentation depending on the people it targets:
-translators, wiki administrators, hackers. This plugin may be complex
-enough to deserve this.
