# DeepDup [![Build Status](https://img.shields.io/travis/ollie/deep_dup/master.svg)](https://travis-ci.org/ollie/deep_dup) [![Code Climate](https://img.shields.io/codeclimate/github/ollie/deep_dup.svg)](https://codeclimate.com/github/ollie/deep_dup) [![Gem Version](https://img.shields.io/gem/v/deep_dup.svg)](https://rubygems.org/gems/deep_dup)

Deep duplicate Ruby objects. Some objects cannot be `dup`ped like `nil`,
`false`, `true`, numbers, symbols and method objects. In those cases
return themselves.

## Usage

No monkey patching:

```ruby
dupped = DeepDup.deep_dup('chunky')
dupped = DeepDup.deep_dup(['chunky', [:bacon, { hi: 5 }]])
dupped = DeepDup.deep_dup(['a', :a, 1, { bacon: { chunky: 'yeah' } }])
dupped = DeepDup.deep_dup(SomeClass.new)

array = [1, 2]
array << array
dupped = DeepDup.deep_dup(array)
```

With monkey patching

```ruby
require 'deep_dup/core_ext/object'

dupped = 'chunky'.deep_dup
dupped = ['chunky', [:bacon, { hi: 5 }]].deep_dup
dupped = ['a', :a, 1, { bacon: { chunky: 'yeah' } }].deep_dup
dupped = SomeClass.new.deep_dup

array = [1, 2]
array << array
dupped = array.deep_dup
```
