# Liner

Lay a liner for your Ruby classes. Liner is designed to enhance simple classes
with some common idioms.

## Usage

You can setup a Liner based class in any of these equivalent ways:

```ruby
Engine = Liner.new(:layout, :fuel)
```
```ruby
class Engine < Liner.new(:layout, :fuel)
end
```
```ruby
class Engine
  liner :layout, :fuel
end
```

Your new class comes with an initializer that takes values in the order you
defined them.
```ruby
e = Engine.new('V6', 'gasoline')
# => #<Engine layout="V6", fuel="gasoline">
```
Or, you can initialize with a hash if you prefer.
```ruby
e = Engine.new(layout: 'V8', fuel: "gasoline")
# => #<Engine layout="V8", fuel="gasoline">
```

Attribute getters and setters are built in.
```ruby
e.fuel            # => "gasoline"
e.fuel = "diesel" # => "diesel"
```

Attributes are accessible via hash style lookup too.
```ruby
e[:layout]        # => "V8"
e[:layout] = "V6" # => "V6"
e[:foo] = "Bar"   # => ArgumentError: Invalid liner attribute: 'foo'
```

Equality methods are also availble.
```ruby
e.eql? Engine.new(layout: 'I4')               # => false
e == Engine.new(layout: 'V6', fuel: 'diesel') # => true
```

## Installation

Add this line to your application's Gemfile:

    gem 'liner'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install liner
