has-properties

has_properties provides an easy way to create basic class definitions with properties. It essentially wraps a lot of attr_(reader/writer/accessor) calls into a neat package with a nifty initializer.

Add this line to your application's Gemfile:

gem 'has-properties'

And then execute:

$ bundle

Or install it yourself as:

$ gem install has-properties

1. Include the HasProperties module
2. Define your properties
3. ??????
4. Profit?

    class Example
      include HasProperties
    
      has_read_properties :readable, :another_readable
      has_write_properties :writable, :another_writable
      has_properties :readable_and_writable
    end
    
    e = Example.new(:readable => 1, :writable => 2, :readable_and_writable => 3)

    e.readable
    => 1

    e.readable = 2
    => NoMethodError

    e.writable
    => NoMethodError

    e.writable = 3
    => 3

    e.readable_and_writable
    => 3

    e.readable_and_writable = 4
    => 4

You don't have to include every property in the initializer hash. For example, the example above defines the :another_readable property, but it was never initialized when the object was created. This means that a call to e.another_readable would equal nil.

    e.another_readable
    => nil
