# exists [![[version]](https://badge.fury.io/rb/exists.svg)](http://badge.fury.io/rb/exists)  [![[travis]](https://travis-ci.org/janlelis/exists.png)](https://travis-ci.org/janlelis/exists)

Like ActiveSupport's presence, but for [Object#null?](https://github.com/janlelis/null_question)

For example, this is useful when setting defaults via or: `object.exists || other_object`


## Setup

Add to your **Gemfile**:

```ruby
gem 'exists'
```


## Usage

```ruby
class NullObject
  def null?
    true
  end
end

nil.exists #=> nil
NullObject.new.exists #=> nil
"some object".exists #=> "some object"
```
