Grab

Grab provides an clean way to fetch multiple values from a hash. Instead of:

def initialize(params)
  foo = params.fetch(:foo)
  bar = params.fetch(:bar)
end

you can write:

def initialize(params)
  foo, bar = params.grab(:foo, :bar)
end

or if some of your params are optional:

def initialize(params)
  foo, bar = params.values(:foo, :bar)
end

Installation

Add this line to your application's Gemfile:

gem 'grab'

And then execute:

$ bundle

Or install it yourself as:

$ gem install grab
