 /**
- * Wrapper function for translation which match the API
- * of gettext()/_() and ngettext().
+ * Class Languages
+ *
+ * Load Shaarli translations using 'gettext/gettext'.
+ * This class allows to either use PHP gettext extension, or a PHP implementation of gettext,
+ * with a fixed language, or dynamically using autoLocale().
  *
- * Not doing translation for now.
+ * Translation files PO/MO files follow gettext standard and must be placed under:
+ *   <translation path>/<language>/LC_MESSAGES/<domain>.[po|mo]
  *
- * @param string $text  Text to translate.
- * @param string $nText The plural message ID.
- * @param int    $nb    The number of items for plural forms.
+ * Pros/cons:
+ *   - gettext extension is faster
+ *   - gettext is very system dependent (PHP extension, the locale must be installed, and web server reloaded)
  *
- * @return String Text translated.
+ * Settings:
+ *   - translation.mode:
+ *     - auto: use default setting (PHP implementation)
+ *     - php: use PHP implementation
+ *     - gettext: use gettext wrapper
+ *   - translation.language:
+ *     - auto: use autoLocale() and the language change according to user HTTP headers
+ *     - fixed language: e.g. 'fr'
+ *   - translation.extensions:
+ *     - domain => translation_path: allow plugins and themes to extend the defaut extension
+ *       The domain must be unique, and translation path must be relative, and contains the tree mentioned above.

+## Translations
+
+Shaarli supports [gettext](https://www.gnu.org/software/gettext/manual/gettext.html) translations
+since `>= v0.9.2`.
+
+Note that only the `default` theme supports translations.
+
+### Contributing
+
+We encourage the community to contribute to Shaarli's translation either by improving existing 
+translations or submitting a new language. 
+
+Contributing to the translation does not require development skill.
+
+Please submit a pull request with the `.po` file updated/created. Note that the compiled file (`.mo`)
+is not stored on the repository, and is generated during the release process.
+
+### How to
+
+First, install [Poedit](https://poedit.net/) tool.
+
+Poedit will extract strings to translate from the PHP source code.
+
+**Important**: due to the usage of a template engine, it's important to generate PHP cache files to extract 
+every translatable string. 
+
+You can either use [this script](https://gist.github.com/ArthurHoaro/5d0323f758ab2401ef444a53f54e9a07)  (recommended)
+or visit every template page in your browser to generate cache files, while logged in.
+
+Here is a list :
+
+```
+http://<replace_domain>/
+http://<replace_domain>/?nonope
+http://<replace_domain>/?do=addlink
+http://<replace_domain>/?do=changepasswd
+http://<replace_domain>/?do=changetag
+http://<replace_domain>/?do=configure
+http://<replace_domain>/?do=tools
+http://<replace_domain>/?do=daily
+http://<replace_domain>/?post
+http://<replace_domain>/?do=export
+http://<replace_domain>/?do=import
+http://<replace_domain>/?do=login
+http://<replace_domain>/?do=picwall
+http://<replace_domain>/?do=pluginadmin
+http://<replace_domain>/?do=tagcloud
+http://<replace_domain>/?do=taglist
+```
+
+#### Improve existing translation
+
+In Poedit, click on "Edit a Translation", and from Shaarli's directory open 
+`inc/languages/<lang>/LC_MESSAGES/shaarli.po`. 
+
+The existing list of translatable strings should have been loaded, then click on the "Update" button.
+
+You can start editing the translation.
+
+![poedit-screenshot](images/poedit-1.jpg)
+
+Save when you're done, then you can submit a pull request containing the updated `shaarli.po`.
+
+#### Add a new language
+
+Open Poedit and select "Create New Translation", then from Shaarli's directory open 
+`inc/languages/<lang>/LC_MESSAGES/shaarli.po`.
+
+Then select the language you want to create. 
+
+Click on `File > Save as...`, and save your file in `<shaarli directory>/inc/language/<new language>/LC_MESSAGES/shaarli.po`.  
+`<new language>` here should be the language code respecting the [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-2) 
+format in lowercase (e.g. `de` for German).
+
+Then click on the "Update" button, and you can start to translate every available string.
+
+Save when you're done, then you can submit a pull request containing the new `shaarli.po`.
+
+### Extend Shaarli's translation
+
+If you're writing a custom theme, or a non official plugin, you might want to use the translation system,
+but you won't be able to able to override Shaarli's translation.
+
+However, you can add your own translation domain which extends the main translation list.
+
+> Note that you can find a live example of translation extension in the `demo_plugin`.
+
+First, create your translation files tree directory:
+
+```
+<your_module>/languages/<ISO 3166-1 alpha-2 language code>/LC_MESSAGES/
+```
+
+Your `.po` files must be named like your domain. E.g. if your translation domain is `my_theme`, then your file will be
+`my_theme.po`.
+
+Users have to register your extension in their configuration with the parameter 
+`translation.extensions.<domain>: <translation files path>`.
+
+Example:
+
+```php
+if (! $conf->exists('translation.extensions.my_theme')) {
+    $conf->set('translation.extensions.my_theme', '<your_module>/languages/');
+    $conf->write(true);
+}
+```
+
+> Note that the page needs to be reloaded after the registration.
+
+It is then recommended to create a custom translation function which will call the `t()` function with your domain.
+For example :
+
+```php
+function my_theme_t($text, $nText = '', $nb = 1)
+{
+    return t($text, $nText, $nb, 'my_theme'); // the last parameter is your translation domain.
+}
+```
+
+All strings which can be translated should be processed through your function:
+
+```php
+my_theme_t('Comment');
+my_theme_t('Comment', 'Comments', 2);
+```
+
+Or in templates:
+
+```php
+{'Comment'|my_theme_t}
+{function="my_theme_t('Comment', 'Comments', 2)"}
+```
+
+> Note than in template, you need to visit your page at least once to generate a cache file.
+
+When you're done, open Poedit and load translation strings from sources:
+
+  1. `File > New`
+  2. Choose your language
+  3. Save your `PO` file in `<your_module>/languages/<language code>/LC_MESSAGES/my_theme.po`.
+  4. Go to `Catalog > Properties...` 
+  5. Fill the `Translation Properties` tab
+  6. Add your source path in the `Sources Paths` tab
+  7. In the `Sources Keywords` tab uncheck "Also use default keywords" and add the following lines:
+  
+```
+my_theme_t
+my_theme_t:1,2
+```
+
+Click on the "Update" button and you're free to start your translations!

- * configure server http://posativ.org/isso/docs/configuration/server/

- 
-
-Problem: by default, Isso thread ID is guessed from the current url (only one thread per page).  
-if we want multiple threads on a single page (shaarli linklist), we must use : the `data-isso-id` client config,
-with data-isso-id being the permalink of an item.
-
-`<section data-isso-id="aH7klxW" id="isso-thread"></section>` 
-`data-isso-id: Set a custom thread id, defaults to current URI.`
-
-Problem: feature is currently broken https://github.com/posativ/isso/issues/27 
-
-Another option, only display isso threads when current URL is a permalink (`\?(A-Z|a-z|0-9|-){7}`) (only show thread
-when displaying only this link), and just display a "comments" button on each linklist item. Optionally show the comment
-count on each item using the API (http://posativ.org/isso/docs/extras/api/#get-comment-count). API requests can be done
-by raintpl `{function` or client-side with js. The former should be faster if isso and shaarli are on ther same server.
-
-Showing all full isso threads in the linklist would destroy layout
