[![Build Status](https://travis-ci.org/matthewrudy/memoist2.png?branch=master)](https://travis-ci.org/matthewrudy/memoist2)

Simple Memoization for Ruby 2.0+.

### Differences between Memoist & Memoist2

Unlike [Memoist], this is **not** a drop-in replacement for old ActiveSupport::Memoizable. Memoist will still work just fine for that if you're using Ruby 2.0+. This project, on the other hand, is just me playing using Module#prepend which makes this stuff very simple.

**[Memoist]**
  * Works on all Rubies.
  * Is quite complicated.
  * Has the exact same api as `ActiveSupport::Memoizable`.

**Memoist2**
  * Only works on `Ruby >= 2.0.0`.
  * Is deliberately much simpler.
  * Has a slightly different API that could totally change.

Example
-------

Memoize an instance method

class Foo
      include Memoist2
  
      def bar
        sleep 1 && 2**10
      end
      memoize :bar
    end

Memoize a class method

class Foo
      include Memoist2
  
      def self.bar
        # something expensive
      end
      memoize_class_method :bar
    end
