Download

You can download the extension directly from the MediaWiki source code repository (browse code). You can get:

One of the extensions tags

Not all extensions have tags. Some extensions have tags for each release, in which case those tags have the same stability as the release. To download a tag

• Go to the tags list
• Click the name of the tag you want to download
• Click "snapshot"

The latest version of one of the extensions branches

Each extension has a master branch containing the latest code (might be unstable). Extensions can have further branches as well.

• Go to the branches list
• Click the branch name
• Click "snapshot"

A snapshot made during the release of a MediaWiki version.

This might be unstable and is not guaranteed to work with the associated MediaWiki version.

• Download snapshot

After you've got the code, save it into the extensions/cldr directory of your wiki.

If you are familiar with git and have shell access to your server, you can obtain the extension, with all its tags and branches, as follows:

cd extensions
git clone https://gerrit.wikimedia.org/r/p/mediawiki/extensions/cldr.git

Installation

1. Download the files from Git or download a snapshot. Choose the version that matches your version of MediaWiki.
2. Create a directory cldr in your $IP/extensions directory.
3. Extract the files to this $IP/extensions/cldr directory.
4. Add
   require_once( "$IP/extensions/cldr/cldr.php" );
   to the bottom of LocalSettings.php.
5. Installation can now be verified through Special:Version of your wiki.

Updating data

The CLDR extension comes with data pre-populated in the language files, but if you want to get the latest data from the Unicode Consortium, you'll need to download it from the CLDR site and then run a rebuild script.

Download newest data from CLDR site:

http://www.unicode.org/cldr/repository_access.html

Example (from within the cldr directory):

wget http://www.unicode.org/Public/cldr/latest/core.zip
unzip core.zip -d core
php rebuild.php

Usage and parameters

Language names

CLDR defines the class LanguageNames which has a static method, getNames(). LanguageNames::getNames accepts three parameters:

1. code - the ISO 639 code of the preferred language to return the list in
2. fbMethod - fallback method. Should be set to one of the following:
   • LanguageNames::FALLBACK_NATIVE (default): Missing entries fallback to the native name
   • LanguageNames::FALLBACK_NORMAL: Missing entries fallback through the fallback chain
3. list - which languages to return. Should be set to one of the following:
   • LanguageNames::LIST_MW_SUPPORTED: Only languages that have localization in MediaWiki
   • LanguageNames::LIST_MW (default): All languages that are in Names.php
   • LanguageNames::LIST_MW_AND_CLDR: All languages that are either in MediaWiki or in CLDR

Example

The following example sets a variable to the list of all languages in MediaWiki and CLDR in English.

if ( is_callable( array( 'LanguageNames', 'getNames' ) ) ) {
    $languages = LanguageNames::getNames( 'en' ,
        LanguageNames::FALLBACK_NORMAL,
        LanguageNames::LIST_MW_AND_CLDR
    );
} else {
    // If we need to display something, use this as fallback
    $languages = Language::getLanguageNames( false );
}

Country names

CLDR defines the class CountryNames which has a static method, getNames(). CountryNames::getNames accepts one parameter:

1. code - the ISO 639 code of the preferred language to return the list in

Example

The following example sets a variable to the list of all countries in CLDR in French.

if ( is_callable( array( 'CountryNames', 'getNames' ) ) ) {
    $countries = CountryNames::getNames( 'fr' );
}

Currency names

CLDR defines the class CurrencyNames which has a static method, getNames(). CurrencyNames::getNames accepts one parameter:

1. code - the ISO 639 code of the preferred language to return the list in

Example

The following example sets a variable to the list of all currencies in CLDR in German.

if ( is_callable( array( 'CurrencyNames', 'getNames' ) ) ) {
    $currencies = CurrencyNames::getNames( 'de' );
}

CLDR includes a very large number of currencies, including many that are no longer in use.
