Cldr_Dates_Times v2.19.2

This is the changelog for Cldr_Dates_Times v2.19.2 released on July 9th, 2024. For older changelogs please consult the release tag on GitHub

Bug Fixes

Reinstate Cldr.DateTime.Format.date_formats/3 which was incorrectly removed in version 2.19. Version 2.19 made efforts to improve the symmetry of Cldr.Date, Cldr.Time and Cldr.DateTime. Part of that work is to have each of those modules contain the functions formats/3 and available_formats/3. It was not intended at this time that the equivalent functions be removed from Cldr.DateTime.Format. Thanks to @tjchambers for the report. Closes #51.

Cldr_Dates_Times v2.19.1

Adds support for formatting using format IDs (atoms that are keys to locale-independent formats) in Cldr.Date.to_string/2 and Cldr.Time.to_string/2. They have been previously supported in Cldr.DateTime.to_string/2 only.
Add MyApp.Cldr.DateTime.Format.common_date_time_format_names/0.
Improve the error message if :hour is outside the valid range.

Cldr_Dates_Times v2.15.0

This is the changelog for Cldr_Dates_Times v2.15.0 released on October 17th, 2023. For older changelogs please consult the release tag on GitHub

Deprecations

The support of :style as a synonym for :format with the functions Cldr.Time.to_string/2, Cldr.Date.to_string/2 and Cldr.DateTime.to_string/2 is now removed. The :style option is now used to influence the use of "at" formats in Cldr.DateTime.to_string/2. :style also remains a valid option for interval formatting.

Enhancements

Add support for "at" style formatting for DateTime structs. This style is documented in TR35 and was introduced in CLDR 43. Thanks to @jueberschlag for the report and motivation to get this done.

Cldr_Dates_Times v2.14.3

This is the changelog for Cldr_Dates_Times v2.14.3 released on October 10th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

Fix typespecs for various functions that allow a string-based locale identifier. Thanks to @jarrodmoldrich for the report. Closes #39.

Cldr_Dates_Times v2.14.0

This is the changelog for Cldr_Dates_Times v2.14.0 released on August 17th, 2023. For older changelogs please consult the release tag on GitHub

Enhancements

Updates to ex_cldr version 2.37.0 which includes data from CLDR release 43
Adds an option :wrapper to Cldr.DateTime.to_string/2, Cldr.Date.to_string/2 and Cldr.Time.to_string/2. The argument is a 2-arity function that receives the parameters string and tag where tag is an atom denoting the time unit being formatted (for example, :minute or :year or :literal). The function must return either iodata or a "safe string" such as that returned by Phoenix.HTML.Tag.content_tag/3. The function can be used to wrap format elements in HTML or other tags.

Cldr_Dates_Times v2.13.3

This is the changelog for Cldr_Dates_Times v2.13.3 released on March 13th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

This release requires (and configures) ex_cldr version 2.36.0 or later. That version fixes the interval format data so that formats required by locales that use 24-hour times are not overwritten by data for 12-hour formats. As a result, formatting intervals using a format key directly (ie one of the keys in the map returned by MyApp.Cldr.DateTime.Format.date_time_interval_formats/1) may find the key has changed.

Fixes localised time interval formatting to respect the locale's preference for 12-hour or 24-hour times. Thanks to @Gladear for the report and collaboration. Closes #35.

Cldr_Dates_Times v2.13.2

This is the changelog for Cldr_Dates_Times v2.13.2 released on March 12th, 2023. For older changelogs please consult the release tag on GitHub

Bug Fixes

Fixed interval formats when the format provided is a string (rather than the normal atom-based predefined formats)
Fixed setting the number system from options (typographical error)
Removed spurious IO.inspect/2 output when the format is a string.

Cldr_Dates_Times v2.13.1

This is the changelog for Cldr_Dates_Times v2.13.1 released on November 12th, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

Fixes doc generation errors (no functional changes to executing code). Closes #34. THanks to @sax for the report and the PR.

Cldr_Dates_Times v2.13.0

This is the changelog for Cldr_Dates_Times v2.13.0 released on October 19th, 2022. For older changelogs please consult the release tag on GitHub

Enhancements

Updates to CLDR 42. The data time formats for several locales have changed from "<date> at <time>" to "<date>, <time>". This is a new category of formats that retain the at formats but these are not yet exposed in ex_cldr_dates_times.

Cldr_Dates_Times v2.12.0

This is the changelog for Cldr_Dates_Times v2.12.0 released on May 7th, 2022. For older changelogs please consult the release tag on GitHub

Cldr_Dates_Times v2.11.0

This is the changelog for Cldr_Dates_Times v2.11.0 released on February 21st, 2022. For older changelogs please consult the release tag on GitHub

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.

Cldr_Dates_Times v2.10.2

This is the changelog for Cldr_Dates_Times v2.10.2 released on January 15th, 2022. For older changelogs please consult the release tag on GitHub

Bug Fixes

Fix Date.to_string/2 when the second argument is a list of options and not a backend module. Previously this would ignore any :backend option and try to use Cldr.default_backend!/0 which would fail if not one was configured. The same fix is applied to Cldr.Time.to_string/2 and Cldr.DateTime.to_string/2.

Cldr_Dates_Times v2.10.1

  {:ok, "Jan 1, 2020 –"}

Cldr_Dates_Times v2.9.1

This is the changelog for Cldr_Dates_Times v2.9.1 released on August 14th, 2021. For older changelogs please consult the release tag on GitHub

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

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

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

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 –"}

All calling Date, Time and DateTime to_string/3 as to_string/1 omitting the backend and providing options. The backend will default to Cldr.default_backend(). An exception will be raised if there is no default backend.
Updates to ex_cldr_calendars 1.0 which includes Cldr.Calendar.week_of_month/1. The result corresponds to the W format which is now implemented as well.

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

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

Correctly calculates week_of_year
Supports Calendar.ISO and any calendar defined with Cldr.Calendar (see ex_cldr_calendars)

Known limitations

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

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:

Create a backend module:

defmodule MyApp.Cldr do
  use Cldr,
    locales: ["en", "fr", "ja"],
    providers: [Cldr.Number, Cldr.Calendar, Cldr.DateTime]

end

Update config.exs configuration to specify this backend as the system default:

config :ex_cldr,
  default_locale: "en",
  default_backend: MyApp.Cldr

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.
