What is the preferred way (better style) to name a namespace in Ruby? Singular or Plural?

Question

What are for you the pros and cons of using:

FooLib::Plugins
FooLib::Plugins::Bar

vs.

FooLib::Plugin
FooLib::Plugin::Bar

naming conventions? And what would you use or what are you using? What is more commonly used in the comunity?

Answer 1

Use:

module FooLib end
module FooLib::Plugins end
class  FooLib::Plugins::Plugin; end #the base for plugins
class  FooLib::Plugins::Bar < FooLib::Plugins::Plugin; end
class  FooLib::Plugins::Bar2 < FooLib::Plugins::Plugin; end

or in a different words:

module FooLib
  module Plugins
    class Plugin; end #the base for plugins
    class Bar < Plugin; end
    class Bar2 < Plugin; end
  end
end

Also arrange the files like this:

- foo_lib/
  - plugins/
    - plugin.rb
    - bar.rb
    - bar2.rb

This is how Rails does it (so this is the Rails Way). I.e. look at the Associations namespace and the Associations::Association class from which all of the classes form the Associations namespace inherits (i.e. Associations::SingularAssociation).
