# Spank

A simple light weight inversion of control container written in ruby.

## Installation

Add this line to your application's Gemfile:

    gem 'spank'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install spank

## Usage

Register a single component and resolve it.

```ruby

  container = Container.new
  container.register(:item) do
    "ITEM"
  end
  container.register(:pants) { jeans }
  container.register(:pants) { dress_pants }
  item = container.resolve(:item)
  
```

Register multiple items, and resolve them.

```ruby

  container = Container.new
  container.register(:pants) { jeans }
  container.register(:pants) { dress_pants }
  pants = container.resolve_all(:item)
  
```

Register a singleton.

```ruby

  container = Container.new
  container.register(:singleton) { fake }.as_singleton
  single_instance = container.resolve(:singleton)
  same_instance = container.resolve(:singleton)
  
```

Automatic dependency resolution.

```ruby

  class Child
    def initialize(mom,dad)
    end
  end
  
  container = Container.new
  container.register(:mom) { mom }
  container.register(:dad) { dad }
  child = sut.build(Child)
      
```

Register selective interceptors.

```ruby

  class Interceptor
    def intercept(invocation)
      invocation.proceed
    end
  end
  
  class Command
    def run(input)
    end
  end
  
  container = Container.new
  container.register(:command) { Command.new }.intercept(:run).with(Interceptor.new)
  proxy = container.resolve(:command)
  proxy.run("hi")
      
```

[Static gateway](http://codebetter.com/jpboodhoo/2007/10/15/the-static-gateway-pattern/) to connect to the container.

```ruby
  
  container = Container.new
  Spank::IOC.bind_to(container)
  Spank::IOC.resolve(:item)
      
```

Enjoy!
