RespondToDig

This gem backports Array#dig and Hash#dig methods from Ruby 2.3+ to earlier versions of Ruby, only if you explicitly call it.

vs RubyDig

• RubyDig has side-effects, but RespondToDig doesn't.
• RespondToDig only supports Array and Hash, but RespondToDig supports any Enumerable classes which have [] method such as Struct.

Installation

Add this line to your application's Gemfile:

gem 'respond_to_dig'

And then execute:

$ bundle

Or install it yourself as:

$ gem install respond_to_dig

            dad: {first: "Homer", last: "Simpson"},
            kids: [
