# Grab

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

    def initialize(params)

      foo = params[:foo]

      bar = params[:bar]

    end

you can write:

    def initialize(params)

      foo, bar = params.grab(:foo, :bar)

    end

If you prefer a KeyError to be raised when a key is missing (like Array#fetch) then use `grab!` instead of `grab`.

## Installation

Add this line to your application's Gemfile:

    gem 'grab'

And then execute:

    $ bundle
