Plurality

Plurality lets you define different sentence pluralizations based on the number of nouns passed to it.

Add this line to your application's Gemfile:

gem 'plurality'

And then execute:

$ bundle

Or install it yourself as:

$ gem install plurality

Plurality relies on on I18n's backend for storing the plural forms. It also follows I18n's own conventions for storing plurals with the added exception of being able to pluralize up to 1000 sentences instead of the limitation of the current language.

If you are using Simple backend then below is what your en.yml would look like. The tokens are the ordinals representation of where the noun falls in the array. They are calculated by the gem numbers_and_words. The additonal token is a special one that is calculated based on the number of nouns minus the ordinal tokens used.

en:
  email:
    subject:
      one: "%{first} was added"
      two: "%{first} and %{second} were added"
      other: "%{first}, %{second} and %{additional} others were added"

Then you simply call Plurality.t or Plurality.translate with the array of nouns and it'll spit out the rest for you.

require 'plurality'

users = %w(Evan Rob Bill Josh)

Plurality.t 'email.subject', nouns: users #=> "Evan, Rob and 2 others were added"

You may also pass additional options that'll be passed through to I18n.translate assuming they don't conflict with the reserved tokens.
