Locale

The editor content language code in the ISO 639-1 format.

Usually the same as the editor language, it can be customized by passing an optional argument to the Locale constructor.

Text direction of the editor content language.

If the content language was passed directly to the Locale constructor, this property represents the direction of that language.

If the editor content language was derived from the editor language, the content language direction is the same as the UI language direction.

The value is either 'ltr' or 'rtl'.

Translates the given message to the uiLanguage. This method is also available in Editor and View.

This method's context is statically bound to the Locale instance and should always be called as a function:

const t = locale.t;
t( 'Label' );

The message can be either a string or an object implementing the Message interface.

The message may contain placeholders (%<index>) for value(s) that are passed as a values parameter. For an array of values, the %<index> will be changed to an element of that array at the given index. For a single value passed as the second argument, only the %0 placeholders will be changed to the provided value.

const t = locale.t;
t( 'Label' );

The message supports plural forms. To specify the plural form, use the plural property. Singular or plural form will be chosen depending on the first value from the passed values. The value of the plural property is used as a default plural translation when the translation for the target language is missing.

const t = locale.t;
t( 'Label' );

• The message should provide an ID using the id property when the message strings are not unique and their translations should be different.

const t = locale.t;
t( 'Label' );

Object that contains translations.

The editor UI language code in the ISO 639-1 format.

If the content language was not specified in the Locale constructor, it also defines the language of the content.

Text direction of the editor UI language. Either 'ltr' or 'rtl'.
