Welcome to our new gem! In this gem, you are able to Deep Clone your Hash and Array very easily. If you are using Ruby outside Rails, and want to deep clone your Reference Data Type, then this gem is perfect for you to fullfill your requirements.
Add this line to your application's Gemfile:
gem 'd_clone'And then execute:
$ bundle install
Or install it yourself as:
$ gem install d_clone
require "d_clone"
Lets first try it for Hashes
x = { a: 1, b: { c: 3, d: [ 11, 12, 13 ], e: 12 } }
clone_x = x.d_clone
puts clone_x[:b]
{:c=>3, :d=>[11, 12, 13], :e=>12}
puts clone_x[:b][:d]
[11, 12, 13]
clone_x[:b][:f] = 14
clone_x[:b][:d] << 14
puts clone_x
{:a=>1, :b=>{:c=>3, :d=>[11, 12, 13, 14], :e=>12, :f=>14}}
puts x
{:a=>1, :b=>{:c=>3, :d=>[11, 12, 13], :e=>12}}
The changes done in 'clone_x' don't reflect in 'x' (x remains intact)
Lets now try it for Arrays
y = [1, 2, [ 3, 4, 5, [ 6, 7 ], { a: 11, b: 12 } ]]
clone_y = y.d_clone
puts y[2][3]
[6, 7]
puts y[2][4]
{:a=>11, :b=>12}
y[2][3] << 88
y[2][4][:c] = 333
puts y
[1, 2, [3, 4, 5, [6, 7, 88], {:a=>11, :b=>12, :c=>333}]]
puts clone_y
[1, 2, [3, 4, 5, [6, 7], {:a=>11, :b=>12}]]
The changes done in 'y' don't reflect in 'clone_y' (clone_y remains intact)
