NilObject

Very simple Null Object pattern implementation. Avdi Grimm has a blog post that gives an excellent introduction to the pattern in Ruby: http://devblog.avdi.org/2011/05/30/null-objects-and-falsiness/

Add this line to your application's Gemfile:

gem 'nil_object'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nil_object

Wherever you want a NilObject simply instantiate one with NilObject.new, conversion methods (such as to_s, to_i, etc.) work like they would on nil, method_missing will return self.

You can extend NilObject to create your own variations of NilObjects as you please.

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
