Defaultinator

Allows you to set default values when setting attributes using attr_accessor or attr_reader. Saves having to define attributes then instantly override them to set a default method.

Turns this:

class Foo
  attr_accessor :things
  def things
    @things ||= []
  end
end

into this:

class Foo
  attr_accessor :things, default: []
end

Also works with attr_accessor or attr_reader in modules, and with passing multiple attributes to define at once.

Installation

Add this line to your application's Gemfile:

gem 'defaultinator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install defaultinator

Usage

If you're not setting default values for the attribute, then just use attr_accessor (or attr_reader) as normal including setting multiple attributes at once.

attr_accessor :foo
attr_accessor :sed, :fred
attr_reader :bar
attr_reader :george, :paul

If you want default values, it's much the same but just pass a hash as the last argument stating what the default value is.

attr_accessor :foo, default: true
attr_accessor :sed, :fred, default: []
attr_reader :bar, default: {}
attr_reader :george, :paul, default: false
