module I18n::Pluralization

Overview

Contains utilities allowing to pluralize translated strings.

Custom pluralization rules can be implemented by subclassing the I18n::Pluralization::Rule abstract class and by implementing a #rule method. Custom pluralization rules can then be registered for specific locale through the use of the #register_rule method.

class CustomRule < I18n::Pluralization::Rule
  def rule(count : Int) : Symbol
    count == 1 ? :one : :other
  end
end

I18n::Pluralization.register_rule("en-CA", CustomRule)
