# AttrDefaultable

Easily add attributes with default values to your classes.

## Installation

Add this line to your application's Gemfile:

    gem 'attr_defaultable'

To optionally slip attr_defaultable into Module so it is available without extending:

    gem 'attr_defaultable', require: 'extend_attr_defaultable'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install attr_defaultable

## Usage

```ruby
class Example
  extend AttrDefaultable
  attr_defaultable :foo, -> { 'bar' }
end
```

This will create a getter/setter pair for your variable `foo`. If the setter is not used before the getter
the proc given will be called and it's result used to set the value of `foo`.

Very useful for creating dependency definitions with protected default values that are evaluated just in time.

## Alternate Usage

By using the alternate gem declaration in your Gemfile or manually
requiring `extend_attr_defaultable` early in your application, you can avoid the explicit `extend`
in your class.

```ruby
class Example
  attr_defaultable :foo, -> { 'bar' }
end
```
