# Naniyatsu

We are stupid.  
We can't remember `instance_of?`, `kind_of?` and `is_a?` method.  

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'naniyatsu'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install naniyatsu

## Usage

```ruby
require 'naniyatsu'

class Hoge
  extend Naniyatsu
end

class Fuga < Hoge
end

class Piyo < Fuga
end

Hoge.new.hoge? # => true
Fuga.new.hoge? # => true
Piyo.new.hoge? # => true

Hoge.new.fuga? # => false
Fuga.new.fuga? # => true
Piyo.new.fuga? # => true

Hoge.new.piyo? # => false
Fuga.new.piyo? # => false
Piyo.new.piyo? # => true
```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake ]spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
