Cldr v1.5.1 Cldr View Source

Cldr provides the core functions to retrieve and manage the CLDR data that supports formatting and localisation.

This module provides the core functions to access formatted CLDR data, set and retrieve a current locale and validate certain core data types such as locales, currencies and territories.

Cldr functionality is packaged into a several packages that each depend on this one. These additional modules are:

  • Cldr.Number.to_string/2 for formatting numbers and Cldr.Currency.to_string/2 for formatting currencies. These functions are contained in the hex package ex_cldr_numbers.

  • Cldr.List.to_string/2 for formatting lists. These function is contained in the hex package ex_cldr_lists.

  • Cldr.Unit.to_string/2 for formatting SI units. These function is contained in the hex package ex_cldr_units.

  • Cldr.DateTime.to_string/2 for formatting of dates, times and datetimes. This function is contained in the hex package ex_cldr_dates_times.

Link to this function all_locale_names() View Source
all_locale_names() :: [Cldr.Locale.locale_name(), ...]

Returns a list of all the locale names defined in the CLDR repository.

Note that not necessarily all of these locales are available since functions are only generated for configured locales which is most cases will be a subset of locales defined in CLDR.

See also: requested_locales/0 and known_locales/0

Link to this function available_locale_name?(locale_name) View Source
available_locale_name?(Cldr.Locale.locale_name() | Cldr.LanguageTag.t()) ::
  boolean()

Returns a boolean indicating if the specified locale is available in CLDR.

The return value depends on whether the locale is defined in the CLDR repository. It does not necessarily mean the locale is configured for Cldr. See also Cldr.known_locale?/1.
