language code does not seem to work

Using a language code as the second parameter to languagename, as described on this page, do not seem to work anymore. To add that option again, replace the function languageName in I18nTags_body.php with this code:

	public static function languageName( &$parser, $code = '', $code2 = '' ) {
		global $wgLang;
		if ( !$code ) return '';
		$native = $code2 === 'native';
		$cldr   = is_callable(array( 'LanguageNames', 'getNames' ));
		if ( !$native && $cldr ) {
			$code2 = $code2 ? $code2 : $wgLang->getCode();
			$languages = LanguageNames::getNames( $code2,
				LanguageNames::FALLBACK_NORMAL,
				LanguageNames::LIST_MW_AND_CLDR
			);
		} else {
			$languages = Language::getLanguageNames( false );
		}
		return isset($languages[$code]) ? $languages[$code] : $code;
	}

To add the possibility to convert in the other direction (i.e. from a language name in some language to an ISO code, you need to edit three files:

In I18nTags.php, add

$parser->setFunctionHook( 'languagecode', array($class, 'languageCode' ) );

in the function efI18nTagsInit, between wfLoadExtensionMessages. In I18nTags_body.php, add a new function like this:

	public static function languageCode( &$parser, $name = '', $lang = '' ) {
		global $wgLang;
		if ( !$name ) return '';
		$native = $lang === 'native';
		$cldr   = is_callable(array( 'LanguageNames', 'getNames' ));
		if ( !$native && $cldr ) {
			$lang = $lang ? $lang : $wgLang->getCode();
			$languages = LanguageNames::getNames( $lang,
				LanguageNames::FALLBACK_NORMAL,
				LanguageNames::LIST_MW_AND_CLDR
			);
		} else {
			$languages = Language::getLanguageNames( false );
		}
		$key = array_search($name, $languages);
		return $key ? $key : $name;
	}

and finally, in I18nTags.magic.php, add the line

'languagecode' => array( 0, 'languagecode' ),

to the array with aliases of all languages used on your wiki, e.g. like this:

/** English (English) */

$magicWords['en'] = array(

'languagename' => array( 0, 'languagename' ),

'languagecode' => array( 0, 'languagecode' ),

);

This is how we use this extension at Säsongsmat.nu. //rotsee 12:07, 29 October 2011 (UTC) 16:35, 31 October 2011 (UTC)

Hmm, by judging from the amount of replies you received, I am not sure whether this extension is still maintained. Did you file a bug on bugzilla for this? You may as well provide your amendments as a patch. Cheers [[kgh]] (talk) 00:54, 3 October 2012 (UTC)

No, I didn't yet, but I guess I should file a bug and submit a patch! rotsee (talk) 07:59, 4 October 2012 (UTC)

Probably you have developer access, too. In this case you could even commit the patch directly and have it reviewed and merged. I think this would even be the faster solution. I could have thought about this earlier. :( Cheers [[kgh]] (talk) 08:23, 4 October 2012 (UTC)

It's unclear what is not working. Please provide minimal example. Nikerabbit (talk) 10:32, 20 February 2016 (UTC)

Transcluding does not work. :-(

We have installed the extension, but sadly it doesn't fit to our needs. it is neither possible to use

<formatnum lang="fa">{{some template}}</formatnum> nor {{some template | lang=fa}} with the formatnum code within the template. The whole text in the template is a simple number!

We quickly deinstalled the extension again. Dennisroczek (talk) 18:55, 4 October 2015 (UTC)

This is expected. You can use the {{#tag:formatnum}} mechanism to work around this. Nikerabbit (talk) 10:34, 20 February 2016 (UTC)

License?

@Nikerabbit: This extension is lacking license information. It will be great if it could be specified. Thanks and cheers [[kgh]] (talk) 16:00, 30 March 2018 (UTC)

It has GPL-2.0-or-later mentioned in two places, so you can update that to where it is missing. Nikerabbit (talk) 06:03, 3 April 2018 (UTC)

Thanks. Ah, I only looked at the common places. Will author a change. [[kgh]] (talk) 07:08, 3 April 2018 (UTC)
