The Unicode Consortium's Common Locale Data Repository (CLDR) contains tons of high-quality locale data such as formatting rules for dates, times, numbers, currencies as well as language, country, calendar-specific names etc.

For localizing applications in Ruby we obviously want to use this incredibly comprehensive and well-maintained resource.

ruby-cldr exports the XML-serialized CLDR data as YAML and Ruby files, for consumption in an I18n context.

ruby-cldr is a work in progress towards a complete and accurate serialization of the CLDR data as Ruby + YAML files.

There are still a number of issues that need to be addressed before it can be considered production-ready.

• Ruby 3.1+
• Thor

gem install bundler
bundle install
thor cldr:download

By default, the thor cldr:export command will export all known components from all locales to the target directory:

thor cldr:export

You can also optionally specify locales and/or components to export as well as the target directory:

# Export the `Numbers` and `Plurals` components for the locales `de`, `fr-FR` and `en-ZA` to the `./data` target directory
thor cldr:export --locales de fr-FR en-ZA --components Numbers Plurals --target=./data

CLDR defines a hierarchy of four draft statuses, used to indicate how confident they are in the data: unconfirmed < provisional < contributed < approved.

By default, ruby-cldr only exports data with a minimum draft status of contributed (i.e., contributed or approved). This is the same threshold that is used by the Unicode Consortium's International Components for Unicode (ICU).

Set the --draft-status= parameter to specify the minimum draft status the data needs in order to be exported:

# Export any data with a minimum draft status of `provisional`
# (i.e., `provisional`, `contributed` or `approved`)).
thor cldr:export --draft-status=provisional

bundle exec ruby test/all.rb
