  • v3.5.2 Changes

    🚀 This is the changelog for Cldr_units v3.5.2 released on April 12th, 2021. For older changelogs please consult the release tag on GitHub

    🐛 Bug Fixes

    • 🛠 Fix getting a unit pattern when the unit value is zero, one or two and there is no pattern for the default unit plural category. Thanks to @syfgkjasdkn for the report. Closes #21.

  • v3.5.1 Changes

    🚀 This is the changelog for Cldr_units v3.5.1 released on April 11th, 2021. For older changelogs please consult the release tag on GitHub

    🐛 Bug Fixes

    • 👉 Use :other plural category to format units which have a value of 0, 1 or 2 when the natural unit pattern has no substitutions. This corrects the situation in locales such as he and ar where the unit pattern for plural category :one has no substitutions. Previously this would means the formatted string for a unit with a vaue of 1 and -1 would both output the same string. Thanks to @jarrodmoldrich for the report and to @voltone for his family's help with hebrew grammar.

  • v3.5.0 Changes

    🚀 This is the changelog for Cldr_units v3.5.0 released on April 8th, 2021. For older changelogs please consult the release tag on GitHub

    Overview

    🚀 In this release the Cldr.Unit.to_string/{1, 2, 3} function has been rewritten and the concrete impementation is now in Cldr.Unit.Format. The primary reasons for rewriting are:

    🐎 1. Improves performance by 20% over the old implementation. 🚀 2. Supports grammatical case and grammatical gender. These allow for better sentence formation in a localised fashion. Only are few locales have the required data for now (for example, fr and de) however more locales will have data in upcoming CLDR releases.

    ✅ Note that full testing of grammatical case and grammatical gender variations is not yet complete.

    🗄 Soft Deprecation

    • 🚀 The function Cldr.Unit.to_iolist/{1, 2, 3} is soft deprecated. It is still available and no deprecation warning is emitted. It will however be removed from the public API in a future release. This function is primarily used to support implementation of Cldr.Unit.to_string/3

    • As of this release, argument checking in Cldr.Unit.to_iolist/3 is less rigorous in order to avoid the relatively expensive argument normalization process happening twice (once in Cldr.Unit.to_string/3 and then again in Cldr.Unit.to_iolist/3).

    🐛 Bug Fixes

    • The new string formatter correctly assembles units with an SI prefix (ie millimeter) in languages such as German where the noun is capitalized.

    • 🛠 Fixes calculating the base unit when the unit is a complex compound unit.

    • ✂ Remove double parsing when calling Cldr.Unit.new/2 and the unit is not in Cldr.Unit.known_units/0

    • Ensure Cldr.Unit.unit_category/1 returns an error tuple if the category is unknown

    ✨ Enhancements

    • 📦 Updated to require ex_cldr version 2.20 which includes CLDR 39 data.

    • Add Cldr.Unit.validate_grammatical_gender/2

    • Add Cldr.Unit.known_grammatical_cases/0

    • Add Cldr.Unit.known_grammatical_genders/0

    • Add Cldr.Unit.known_measurement_system_names/0

    • ➕ Add Cldr.Unit.invert/1 to invert a "per" unit. This allows for increased compatibility for conversions. For example, "liters per 100 kilometers" is a measure of consumption, as is "miles per gallon". However these two units are not convertible without inverting one of them first since one is "volume per length" and the other is "length per volume".

    • ➕ Add Cldr.Unit.conversion_for/2 to return a conversion list used when converting one unit to another.

    • ➕ Add Cldr.Unit.grammatical_gender/2 to return the grammatical gender for a given unit and locale

    • ➕ Add Cldr.Unit.conversion_for/2 to return a conversion list used when converting one unit to another.

    • Add support for grammatical cases for Cldr.Unit.to_string/2 and Cldr.Unit.to_iolist/2. Not all locales support more than the nominative case. The nominative case is the default. Any configured "Additional Units" in a backend module will need to be modified to put the localisations a map with the key :nominative. See the readme for more information on migrating additional units. On example is:

      defmodule MyApp.Cldr do
use Cldr.Unit.Additional

    use Cldr, locales: ["en", "fr", "de", "bs", "af", "af-NA", "se-SE"], default_locale: "en", providers: [Cldr.Number, Cldr.Unit, Cldr.List]

    unit_localization(:person, "en", :long, nominative: %{ one: "{0} person", other: "{0} people" }, display_name: "people" ) end

    
* 👌 Support conversions where one of the base units is the inverted conversion of the other. This allows conversion between, for example, `mile per gallon` and `liter per 100 kilometer`. These are both compound units of `length` and `volume` but are inverse representations from each other.
