◆ bcp47()

static LanguageCode::bcp47 (   $code)
static

Get the normalised IETF language tag See unit test for examples.

See mediawiki.language.bcp47 for the JavaScript implementation.

Parameters
string$codeThe language code.
Returns
string A language code complying with BCP 47 standards.

◆ getDeprecatedCodeMapping()

static array static array static LanguageCode::getDeprecatedCodeMapping ( )
static

Returns a mapping of deprecated language codes that were used in previous versions of MediaWiki to up-to-date, current language codes.

This array is merged into $wgDummyLanguageCodes in Setup.php, along with the fake language codes 'qqq' and 'qqx', which are used internally by MediaWiki's localisation system.

Returns
string[]

◆ getNonstandardLanguageCodeMapping()

static LanguageCode::getNonstandardLanguageCodeMapping ( )
static

Returns a mapping of non-standard language codes used by (current and previous version of) MediaWiki, mapped to standard BCP 47 names.

This array is exported to JavaScript to ensure mediawiki.language.bcp47 stays in sync with LanguageCode::bcp47().

Returns
string[]

◆ replaceDeprecatedCodes()

static LanguageCode::replaceDeprecatedCodes (   $code)
static

Replace deprecated language codes that were used in previous versions of MediaWiki to up-to-date, current language codes.

Other values will returned unchanged.

Parameters
string$codeOld language code
Returns
string New language code

Member Data Documentation

◆ $deprecatedLanguageCodeMapping

array LanguageCode::$deprecatedLanguageCodeMapping
staticprivate
Initial value:
= [
'als' => 'gsw'

Mapping of deprecated language codes that were used in previous versions of MediaWiki to up-to-date, current language codes.

These may or may not be valid BCP 47 codes; they are included here because MediaWiki renamed these particular codes at some point.

Mapping from deprecated MediaWiki-internal language code to replacement MediaWiki-internal language code.

◆ $nonstandardLanguageCodeMapping

array static array LanguageCode::$nonstandardLanguageCodeMapping
staticprivate
Initial value:
= [
'cbk-zam' => 'cbk'

Mapping of non-standard language codes used in MediaWiki to standardized BCP 47 codes.

These are not deprecated (yet?): IANA may eventually recognize the subtag, in which case the -x- infix could be removed, or else we could rename the code in MediaWiki, in which case they'd move up to the above mapping of deprecated codes.

As a rule, we preserve all distinctions made by MediaWiki internally. For example, de-formal becomes de-x-formal instead of just de because MediaWiki distinguishes de-formal from de (for example, for interface translations). Similarly, BCP 47 indicates that kk-Cyrl SHOULD not be used because it "typically does not add information", but in our case MediaWiki LanguageConverter distinguishes kk (render content in a mix of Kurdish variants) from kk-Cyrl (convert content to be uniformly Cyrillic). As the BCP 47 requirement is a SHOULD not a MUST, kk-Cyrl is a valid code, although some validators may emit a warning note.
