Using ruby keyword in application

Ruby

Hey all,

In this line of code:

class Class
def dual_accessor(*attributes)
options = attributes.extract_options!
attributes.each do |attribute|
class_eval <<-ruby
class_inheritable_accessor :#{attribute}

    singleton_class.send :alias_method, :read_#{attribute},

:#{attribute}

    def self.#{attribute}(value = :__read__)
      if value == :__read__
        read_#{attribute}
      else
        self.#{attribute} = value
      end
    end
  ruby
  self.send(attribute, options[:default]) if options[:default]
end

end
end

I’m not sure what “<<-ruby ruby” is doing in there and how it impacts
the code.

Thanks for response.
