enhancements-1

 Enhancements

  • Updates to ex_cldr version 2.26.0 and ex_cldr_numbers version 2.25.0 which use atoms for locale names and rbnf locale names. This is consistent with other elements of t:Cldr.LanguageTag where atoms are used when the cardinality of the data is fixed and relatively small and strings where the data is free format.

bug-fixes-6

 Bug fixes

  • Open interval formats can now also be called directly on the backend. For example:

      iex> MyApp.Cldr.Date.Interval.to_string ~D[2020-01-01], nil
  {:ok, "Jan 1, 2020 –"}

bug-fixes-7

 Bug fixes

  • When formatting an open interval (one side is nil) the backend function date_time_interval_fallback/2 is used to retrieve the format pattern. Previously this function was being called with default parameters. Now it is properly called with a locale and a calendar.

cldr_dates_times-v2-9-0

 Cldr_Dates_Times v2.9.0

This is the changelog for Cldr_Dates_Times v2.9.0 released on August 14th, 2021. For older changelogs please consult the release tag on GitHub

bug-fixes-8

 Bug fixes

  • Fix splitting interval formats when there is no repeating field. Use the principal that standalone formats are equivalent to normal formats when splitting. ie, for this purposes "L" == "M". This means the locale "fa" no longer raises an exception.

enhancements-4

 Enhancements

  • Allow formatting of intervals where one side is nil. This will produce an open-ended interval. Only one side of the interval can be nil. Thanks to @woylie for the request. Closes #23.

Examples

  iex> Cldr.Date.Interval.to_string ~D[2020-01-01], nil, MyApp.Cldr,
  ...> format: :short
  {:ok, "1/1/20 –"}

  iex> Cldr.Time.Interval.to_string ~U[2020-01-01 00:00:00.0Z], nil, MyApp.Cldr,
  ...> format: :long, style: :flex
  {:ok, "12:00:00 AM UTC –"}

  iex> Cldr.DateTime.Interval.to_string ~U[2020-01-01 00:00:00.0Z], nil, MyApp.Cldr
  {:ok, "Jan 1, 2020, 12:00:00 AM –"}

enhancements-5

 Enhancements

  • Updated to ex_cldr version 2.23.0 which changes the names of some of the field in the "-u-" extension to match the CLDR canonical name. In particular the field name hour_cycle changes to hc. The values for hc also change to the canonical forms of :h12, :h11, :h23 and :h24.

defmodule MyApp.Cldr do
  use Cldr, providers: [Cldr.Number, Cldr.DateTime], default_locale: "en"
end

defmodule MyApp do
  alias MyApp.Cldr

  def some_fun do
    Cldr.Date.to_string Date.utc_today()

 Cldr_Dates_Times v2.0.0

This is the changelog for Cldr_Dates_Times v2.0 released on June 9th, 2019. For older changelogs please consult the release tag on GitHub

This release depends on ex_cldr_calendars which provides the underlying calendar calculations as well as providing a set of additional calendars.

breaking-changes

 Breaking Changes

  • ex_cldr_dates_times requires a minimum Elixir version of 1.8. It depends on Calendar capabilities built into this and later release.

  • ex_cldr_dates_times now depends upon ex_cldr version 2.0. As a result it is a requirement that at least one backend module be configured as described in the ex_cldr readme.

  • The public API is now based upon functions defined on a backend module. Therefore calls to functions such as Cldr.DateTime.to_string/3 should be replaced with calls to MyApp.Cldr.DateTime.to_string/3 (assuming your configured backend module is called MyApp.Cldr).

enhancements-13

 Enhancements

known-limitations

 Known limitations

  • Does not calculate week_of_month. If called will return 1 for all input values.

migration

 Migration

ex_cldr_dates_times uses the configuration set for the dependency ex_cldr. See the documentation for ex_cldr

Unlike ex_cldr_dates_times version 1, version 2 requires one or more backend modules to host the functions that manage CLDR data. An example to get started is:

  1. Create a backend module:
defmodule MyApp.Cldr do
  use Cldr,
    locales: ["en", "fr", "ja"],
    providers: [Cldr.Number, Cldr.Calendar, Cldr.DateTime]

end
  1. Update config.exs configuration to specify this backend as the system default:
config :ex_cldr,
  default_locale: "en",
  default_backend: MyApp.Cldr
  1. Replace calls to Date. Time and DateTime functions to_string/2 with calls to to_string/3 where the second parameter is a backend module.
