Recordkeeper

Recordkeeper is a ruby gem that works like Python's Counter method. Built as a monkey patch to the Array class, recordkeeper takes an array and returns a hash where the keys are the array's values, and the values are the instances in which the values appear in the original array.

So for example:

[1, 1, 1, 4, 2, 5].recordkeeper returns 4 => 1, 2 => 1, 5=>1

["apple", "apple", "banana", "cartoon"].recordkeeper returns "banana"=>1, "cartoon"=>1

Installation

Add this line to your application's Gemfile:
