Properties Pattern

Use the Properties pattern (e.g. JavaScript's object system) in Ruby.

Installation

Add this line to your application's Gemfile:

gem 'properties_pattern'

And then execute:

$ bundle

Or install it yourself as:

$ gem install properties_pattern

Usage

Create a new object with Properties::BASE.inherit new_properties_hash, NOT Properties.new (otherwise, prototypes will not work out of the box).

Inherit from an existing object with existing_object.inherit new_properties_hash

Get property from object or it's prototype chain with existing_object.get property_name

Set property in object with existing_object.put property_name, property_value

See if object has property with existing_object.has? property_name

Remove property from object with existing_object.remove property_name
