Changelog for Cldr v2.7.0

This is the changelog for Cldr v2.7.0 released on April 22nd, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Updates to CLDR version 35.1.0 which is primarily related to the change of Japanese era with the ascension of a new emporer on April 1st.

Changelog for Cldr v2.6.2

This is the changelog for Cldr v2.6.2 released on April 16th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Adds Cldr.flag/1 that returns a binary unicode grapheme representing a flag for a given territory

  • The parameters provided to Cldr.Plug.SetLocale.init/1 are now conformed more precisely based upon the provided options. This ensures that the keys :cldr and :gettext are set from other options if they are not provided directly.

Bug Fixes

  • Cldr.Plug.SetLocale.init/1 would raise an exception if no :gettext key was specified. This is now corrected.

Changelog for Cldr v2.6.1

This is the changelog for Cldr v2.6.1 released on April 13th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Correctly resolves the :data_dir param for a backend module. Thanks to @erikreedstrom for the report. Closes #123.

  • Raises if a backend module configures an :otp_app that is not known

Changelog for Cldr v2.6.0

This is the changelog for Cldr v2.6.0 released on March 28th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

There is one unresolved issue in this implementation related to plural rules for the locale "kw" (Cornish).

The plural rule definition for :other in the repository is:

"pluralRule-count-other": " @integer 4~19, 100, 1000000, … @decimal 0.1~0.9, 1.1~1.7, 10.0, 100.0, 1000.0 100000.0 1000000.0, …",

However in rules testing, the values 1000.0, 10000.0 and 100000.0 are resolving to category :two rather than :other. Until this is resolved, these data points are removed from the test data.

Changelog for Cldr v2.5.0

This is the changelog for Cldr v2.5.0 released on March 23rd, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Adds the global :ex_cldr configuration key :default_backend.

  • Adds Cldr.default_backend/0 which will return the configured default backend or will raise an exception if not is configured.

  • Where appropriate, Cldr.* will now use Cldr.default_backend() as a default parameter.

Changelog for Cldr v2.4.3

This is the changelog for Cldr v2.4.3 released on March 20th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix Cldr.validate_locale/1 @spec error and remove spurious @dialyzer directives

Changelog for Cldr v2.4.2

This is the changelog for Cldr v2.4.2 released on March 15th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Exclude Cldr.Currency from the list of known providers so that it won't be compiled twice when working with ex_cldr_numbers.

Changelog for Cldr v2.4.1

This is the changelog for Cldr v2.4.1 released on March 14th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Makes generation of documentation for backend modules optional. This is implemented by the :generate_docs option to the backend configuration. The default is true. For example:
defmodule MyApp.Cldr do
  use Cldr,
    default_locale: "en-001",
    locales: ["en", "ja"],
    gettext: MyApp.Gettext,
    generate_docs: false
end

Changelog for Cldr v2.4.0

This is the changelog for Cldr v2.4.0 released on March 10th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Minor restructuring of the locale files. Calendar map keys are harmonised to have the same names and meanings. This would not normally be user visible but a change in data format suggests a minor version bump to easy version management.

  • Restructure the data returned by Cldr.Config.week_info/0 to also encode week days as numbers in the range 1..7 where 1 is Monday.

Changelog for Cldr v2.3.2

This is the changelog for Cldr v2.3.2 released on March 8th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Does a better job of detecting a required JSON library and raising at compile time if no such library can be found. In order of priority the search for a JSON library is:

    • the key :json_library under the application key :ex_cldr
    • a configured Phoenix json_library
    • a configured Ecto json_library
    • Jason if configured
    • Poison if configured

Changelog for Cldr v2.3.1

This is the changelog for Cldr v2.3.1 released on March 6th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Fix dialyzer errors. In some cases, notably related to nimble_parsec, errors are generated that need to be fixed in a dependency. These errors are added to the .dialyzer_ignore_warnings file for now.

Changelog for Cldr v2.3.0

This is the changelog for Cldr v2.3.0 released on March 4th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • Adds Cldr.LanguageTag.to_string/1 which converts a Cldr.LanguageTag{} into a language tag string. This is useful when creating a collator that is based upon libicu since that collator will apply the configuration specified by the u extension in the language tag. For example:
iex> {:ok, locale} = Cldr.validate_locale "en-US-u-co-phonebk-nu-arab", MyApp.Cldr
iex> Cldr.LanguageTag.to_string(locale)
"en-Latn-US-u-ca-phonebk-nu-arab"

Bug Fixes

  • Fix a bug when parsing some locale strings which have extensions. An extension may have a list of "keyword-type" pairs or simply "keyword". Parsing was failing when only the "keyword" form was used. For example the following used to fail, but is now parsed correctly:
iex> {:ok, locale} = Cldr.validate_locale "en-US-u-co-ca", MyApp.Cldr
{:ok,
 %Cldr.LanguageTag{
   canonical_locale_name: "en-Latn-US",
   cldr_locale_name: "en",
   extensions: %{},
   gettext_locale_name: nil,
   language: "en",
   language_subtags: [],
   language_variant: nil,
   locale: %{calendar: "gregory", collation: "standard"},
   private_use: [],
   rbnf_locale_name: "en",
   requested_locale_name: "en-US",
   script: "Latn",
   territory: "US",
   transform: %{}
 }}
  • Fix a race condition when starting up the compile-time locale cache

Changelog for Cldr v2.2.7

This is the changelog for Cldr v2.2.7 released on February 23rd, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

Correctly validates locales that are not pre-compiled into a backend. At compile time, all configured locales are generated from the CLDR data. However not all valid locales can be predefined - especially those that have variants, subtags or extensions or use a different casing to the canonical form.

For example, the following would fail in prior releases even though it is perfectly valid since language tags are defined to be case insensitive:

iex> MyApp.Cldr.validate_locale "en-au"
{:error, {Cldr.UnknownLocaleError, "The locale \"en-au\" is not known."}}

Similarly, it is expected that both the POSIX and IEEE formats of a language tag are acceptable, meaning that a - or _ should be acceptable. Again, in prior releases this would result in an error:

iex> MyApp.Cldr.validate_locale "en_AU"
{:error, {Cldr.UnknownLocaleError, "The locale \"en_AU\" is not known."}}

Lastly, when using locale extensions, subtags or variants the validation would fail:

MyApp.Cldr.validate_locale "en-u-ca-buddhist"
{:error, {Cldr.UnknownLocaleError, "The locale \"en_AU\" is not known."}}

Each of these examples now correctly validates:

iex> TestBackend.Cldr.validate_locale "en-au"
{:ok,
 %Cldr.LanguageTag{
   canonical_locale_name: "en-Latn-AU",
   cldr_locale_name: "en-AU",
   extensions: %{},
   gettext_locale_name: "en",
   language: "en",
   language_subtags: [],
   language_variant: nil,
   locale: %{},
   private_use: [],
   rbnf_locale_name: "en",
   requested_locale_name: "en-AU",
   script: "Latn",
   territory: "AU",
   transform: %{}
 }}
iex> TestBackend.Cldr.validate_locale "en_au"
{:ok,
 %Cldr.LanguageTag{
   canonical_locale_name: "en-Latn-AU",
   cldr_locale_name: "en-AU",
   extensions: %{},
   gettext_locale_name: "en",
   language: "en",
   language_subtags: [],
   language_variant: nil,
   locale: %{},
   private_use: [],
   rbnf_locale_name: "en",
   requested_locale_name: "en-AU",
   script: "Latn",
   territory: "AU",
   transform: %{}
 }}
iex> TestBackend.Cldr.validate_locale "en-u-ca-buddhist"
{:ok,
  %Cldr.LanguageTag{
    canonical_locale_name: "en-Latn-US",
    cldr_locale_name: "en",
    extensions: %{},
    gettext_locale_name: "en",
    language: "en",
    language_subtags: [],
    language_variant: nil,
    locale: %{calendar: :buddhist},
    private_use: [],
    rbnf_locale_name: "en",
    requested_locale_name: "en",
    script: "Latn",
    territory: "US",
    transform: %{}
}}

Changelog for Cldr v2.2.2

This is the changelog for Cldr v2.2.2 released on February 9th, 2019. For older changelogs please consult the release tag on GitHub

Enhancements

  • add Cldr.Config.currencies_for/2 to return a map of the currency definition for a locale

Changelog for Cldr v2.2.1

This is the changelog for Cldr v2.2.1 released on January 30th, 2019. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Correctly add the gettext locale to the language tag returned by <backend>.default_locale and Cldr.default_locale/2. Thanks to @erikreedstrom. Closes #106.

Enhancements

  • Added a section on migrating from Cldr 1.x to 2.x.

Changelog for Cldr v2.2.0

This is the changelog for Cldr v2.2.0 released on December 23nd, 2018. For older changelogs please consult the release tag on GitHub

Enhancements

  • Bump nimble_parsec to version 0.5 which has some breaking changes from 0.4 that affects the language tag parser.

  • Use IO.warn/1 for compiler warnings related to global configuration and Cldr providers configuration for a backend.

Changelog for Cldr v2.1.0

This is the changelog for Cldr v2.1.0 released on December 1st, 2018. For older changelogs please consult the release tag on GitHub

Bug Fixes

  • Don't issue a bogus global config deprecation warning.

Enhancements

  • Revises the Cldr provider strategy - again. Rather than try to auto-discover available provider modules and configuring them automatically they are now configured under the :provider key. The readme contains further information on configuring providers. For example:
defmodule MyApp.Cldr do
  use Cldr,
    locales: ["en", "zh"],
    default_locale: "en",
    providers: [Cldr.Number, Cldr.List]
end

The default behaviour is the same as Cldr 2.0 in that all known cldr providers are configured.

Changelog for Cldr v2.0.4

This is the changelog for Cldr v2.0.4 released on November 26th, 2018. For older changelogs please consult the release tag on GitHub

Bug fixes

  • Dependency plugin check was using Mix.Project.in_project/3 which actually changes directory which during compilation is a bad thing (since compilation is in parallel and within a single Unix process). The plugin dependency list is now static. Thanks to @robotvert. Closes #93.

Changelog for Cldr v2.0.3

This is the changelog for Cldr v2.0.3 released on November 25th, 2018. For older changelogs please consult the release tag on GitHub

Bug fixes

  • Check for a json library existence as early as possible in the compile cycle since it is required during compilation of Cldr.

Changelog for Cldr v2.0.2

This is the changelog for Cldr v2.0.2 released on November 24th, 2018. For older changelogs please consult the release tag on GitHub

Enhancements

  • Move minimal Decimal version to 1.5

Bug fixes

  • Cldr.Substitution.substitute/2 now conforms to its documentation and substitutes a list of terms into a list format

Changelog for Cldr v2.0.1

This is the changelog for Cldr v2.0.1 released on November 22, 2018. For older changelogs please consult the release tag on GitHub

Bug fixes

  • Fixes a bug whereby a backend configured with locales, but no default locale (and no global configuration), would crash during compilation

Changelog for Cldr v2.0.0

This is the changelog for Cldr v2.0.0 released on November 22, 2018. For older changelogs please consult the release tag on GitHub

Enhancements

See also Breaking Changes below.

  • Transforms the regex's for currency spacing to be compatible with the elixir regex engine. This supports improved conformance for currency formatting in ex_cldr_numbers
  • Removes the need for Phoenix as a dependency in tests. Thanks to @lostkobrakai. Closes #84.
  • Print deprecation message if the global config is used for more than :json_library and :default_locale
  • Align Cldr/get_locale/1/0 and Cldr.put_locale/2/1 with Gettext. See Cldr.get_locale/1, Cldr.get_locale/0, Cldr.put_locale/2 and Cldr.put_locale/1
  • Improve performance of Cldr.Gettext.Plural and align its return better with Gettext
  • Add the 'miscellaneous' number formats to the locale definition files. This allows formatting of "at least", "approximately", "at most" and "range". These formats will be used in ex_cldr_numbers.

Purpose of the changes

Version 2.0 of Cldr is focused on re-architecting the module structure to more closely follow the model set by Phoenix, Ecto, Gettext and others that also rely on generating a public API at compile time. In Cldr version 1.x, the compile functions were all hosted within the ex_cldr package itself which has created several challenges:

  • Only one configuration was possible per installation
  • Dependency compilation order couldn't be determined which meant that when Gettext was configured a second, forced, compilation phase was required whenever the configuration changed
  • Code in the ex_cldr _build directory would be modified when the configuration changed

New structure and configuration

In line with the recommended strategy for configurable library applications, Cldr now requires a backend module be defined that hosts the configuration and public API. This is similar to the strategy used by Gettext, Ecto, Phoenix and others. These backend modules are defined like this:

defmodule MyApp.Cldr do
  use Cldr, locales: ["en", "zh"]
end

For further information on configuration, consult the readme.

Migrating from Cldr 1.x to Cldr version 2.x

Although the api structure is the same in both releases, the move to a backend module hosting configuration and the public API requires changes in applications using Cldr version 1.x. The steps to migrate are:

  1. Change the dependency in mix.exs to {:ex_cldr, "~> 2.0"}
  2. Define a backend module to host the configuration and public API. It is recommended that the module be named MyApp.Cldr since this will ease migration through module aliasing.
  3. Change calls to Cldr.function_name to MyApp.Cldr.function_name. The easiest way to do this is to alias the backend module. For example:
defmodule MyApp.SomeModule do
# alias the backend module so that calls to Cldr functions still work
  alias MyApp.Cldr

  def some_function do
    IO.puts Cldr.known_locale_names
  end
end

Breaking Changes

  • Configuration has changed to focus on the backend module, then otp app, then global config. All applications are required to define a backend module.
  • The Public API moves to a configured backend module. Functions previous called on Cldr should be called on MyApp.Cldr.
  • The ~L sigil has been removed. The public api functions support either a locale name (like "en") or a language tag.
  • Cldr.Plug.AcceptLanguage and Cldr.Plug.SetLocale need to have a config key :cldr to specify the Cldr backend to be used.
  • The Mix compiler :cldr is obsolete. It still exists so configuration doesn't break but its no a :noop. It should be removed from your configuration.
  • Cldr.Config.get_locale/1 now takes a config or backend parameter and has become Cldr.Config.get_locale/2.
  • Cldr.get_current_locale/0 is renamed to Cldr.get_locale/0 to better align with Gettext
  • Cldr.put_current_locale/1 is renamed to Cldr.put_locale/1 to better align with Gettext
