Add methods to manipulate the order of the entries in the Hash object.

Installation

Add this line to your application's Gemfile:

gem 'hash_order_helper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hash_order_helper

Usage

require 'hash_order_helper'

hash = {b: 200, a: 100, c: 150}

hash.sort_pair
#=> {:a=>100, :b=>200, :c=>150}

hash.unshift(d: 300)
#=> {:d=>300, :b=>200, :a=>100, :c=>150}

The following methods are added:

• sort_pair -> Hash
• sort_pair! -> Hash
• sort_pair_by {|key, value| ... } -> Hash
• sort_pair_by! {|key, value| ... } -> Hash
• at(nth) -> Array
• insert(nth, hash) -> Hash
• last -> Array
• last(n) -> Array
• pop -> Array
• pop(n) -> Array
• nd_push(hash) -> Hash non-destructive (alias: +)
• push(hash) -> Hash (alias: <<)
• nd_unshift(hash) -> Hash non-destructive
• unshift(hash) -> Hash
• >>(receiver_hash) -> Hash

>> method

require 'hash_order_helper'

hash = {b: 200, a: 100, c: 150}

{d: 300} >> hash
#=> {:d=>300, :b=>200, :a=>100, :c=>150}
