mw.language

Methods for transforming message syntax.

Base language object with methods related to language support, attempting to mirror some of the functionality of the Language class in MediaWiki:

  • storing and retrieving language data
  • transforming message syntax ({{PLURAL:}}, {{GRAMMAR:}}, {{GENDER:}}, {{#FORMAL:}})
  • formatting numbers

Properties

data :Objectstatic #

Language-related data (keyed by language, contains instances of mw.Map).

Exported dynamically by the ResourceLoader\LanguageDataModule class in PHP.

To set data:

// Override, extend or create the language data object of 'nl'
mw.language.setData( 'nl', 'myKey', 'My value' );

// Set multiple key/values pairs at once
mw.language.setData( 'nl', { foo: 'X', bar: 'Y' } );

To get GrammarForms data for language 'nl':

var grammarForms = mw.language.getData( 'nl', 'grammarForms' );

Possible data keys:

  • digitTransformTable
  • separatorTransformTable
  • minimumGroupingDigits
  • formalityIndex
  • grammarForms
  • pluralRules
  • digitGroupingPattern
  • fallbackLanguages
  • bcp47Map
  • languageNames
