Enrichments (e9s) module for localized pluralization
Rich-pluralization is a module of E9s (http://github.com/archan937/e9s) which provides localized pluralization in combination with i18n. Doing this enables you to only translate words in singular form as the module pluralizes the translation for you.
As as example, in the Dutch locale you can do the following:
>> "Appendix".pl => "Appendices"
Dutch pluralization rules are provided along with Rich-pluralization and has a 86% test coverage out of 54977 words which are provided by INL. Unfortunately we can’t distribute the complete list of nouns due to the closed nature of the database.
Rich-pluralization preserves the casing in the pluralized result:
>> "huis".pl => "huizen" >> "Huis".pl => "Huizen" >> "HUIS".pl => "HUIZEN"
Note: I18n.locale is :nl
Install the Rich-pluralization gem:
sudo gem install rich_pluralization
Add rich_pluralization in environment.rb as a gem dependency:
config.gem "rich_pluralization"
Install the Rich-pluralization plugin:
./script/plugin install git://github.com/archan937/rich_pluralization.git
Install i18n if you haven’t already:
sudo gem install i18n
Set the default locale to :nl in environment.rb:
config.i18n.default_locale = :nl
Run the Rails console:
./script/console
Start pluralizing in Dutch:
>> "Academicus".pl => "Academici"
Just call the pl method on string or symbols to pluralize.
Note: I18n.locale is :nl
>> "brief".pl => "brieven" >> "gebruiker".pl => "gebruikers" >> :museum.pl => "musea" >> "afspraak".pl => "afspraken"
Rich-pluralization has enriched the String class with several inflection methods such as upcase_first, cp_case, upcase_first! and pluralize!. Please visit http://github.com/archan937/rich_pluralization/blob/master/lib/rich/pluralization/core/string/inflections.rb to see all the methods.
Rich-pluralization inflections resembles the inflections of ActiveSupport::Inflector. Unfortunately, specifying inflections within config/initializers/inflections.rb influences your Rails application and thus causes great problems.
To specify pluralization rules for different locales. You have to use regular expressions and put them in config/locales/language.yml.
Note: specified in config/locales/nl.yml

This Rails gem / plugin depends on:
i18n
http://github.com/svenfuchs/i18n
- Complete the Dutch and Spanish inflections
- Most String inflection methods are also defined in rich_i18n (keep it DRY)
- Check whether to make Rich-pluralization compatible with Rails 3
