# exists [![[version]](https://badge.fury.io/rb/exists.svg)](https://badge.fury.io/rb/exists) [![[ci]](https://github.com/janlelis/exists/workflows/Test/badge.svg)](https://github.com/janlelis/exists/actions?query=workflow%3ATest)
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"
```
