# Pluralize helper for French language.
#
# Because French pluralization has special rules :
# Example :
# pluralize(0, "degré") # => "0 degré"
# pluralize(1, "degré") # => "1 degré"
# pluralize(2, "degré") # => "2 degrés"
# pluralize(0.5, "degré") # => "0.5 degré"
# pluralize(1.9, "degré") # => "1.9 degré"
# pluralize(-1.9, "degré") # => "-1.9 degré"
# pluralize(-2, "degré") # => "-2 degrés"
#
# Options :
# :without_count : if you don't want to output the count (only the word),
# :plural : to use a custom plural.
#
def pluralize(count, singular, options = {})
  "".tap do |result|
    result << "#{count || 0} " unless options[:without_count]
    result << (count.to_i > -2 && count.to_i < 2 ? singular : (options[:plural] || singular.pluralize)).to_s
  end
end

cool !

Wouldn't gettext be able to handle this?

afranke ? Why do you want to use gettext ? Rails already got a full internationalization system (Rails i18n API) since Rails 2.3, see : http://guides.rubyonrails.org/i18n.html to learn how to use it.

Doesn't this i18n API already handle pluralization? I don't use Ruby nor Rails, but in other languages gettext is the de facto standard and it takes care of plurals. So I find it weird that you might need such a code and that it's not already done in the API.

The Rails i18n system provides a lot of features to translate strings, interpolation, date/time localizing... And of course, know how to pluralize words.
This helper does not implement "singular" or "pluralize" which are already implemented in Rails i18n.
This is just an additionnal language RULE.
In English we say "0 + plural", in other language it may be different. In french we say "0 + singular". This helper is to override this rule for the French language.

Ok, nevermind then.
