# Attribeauty

I just wanted a quick, simple way to initialize mutable objects. This is it.
There are so many of these, but none were what I wanted.

## Installation

Install the gem and add to the application's Gemfile by executing:

    $ bundle add attribeauty

If bundler is not being used to manage dependencies, install the gem by executing:

    $ gem install attribeauty

## Usage

Inherit from `Attribeauty::Base` and then add attribute with the type you want.
Initialize with these and they will be cast to that attribute.
Use `assign_attributes` to update the object.


```
class MyClass < Attribeauty::Base
  attribute :first, :string
  attribute :second, :integer
  attribute :third, :float
  attribute :forth, :boolean
  attribute :fifth, :time
  attribute :sixth, :koala
end

instance = MyClass.new(first: 456)
instance.first # => "456"
instance.assign_attributes(second: "456")
instance.second # => 456
instance.first = 9000
instance.first # => "9000"
```

To add your own types, simply have a class that handles `MyClassName.new.cast(value)`:

```
Attribeauty.configure do |config|
  config.types[:koala] = MyTypes::Koala
end

module MyTypes
  class Koala
    def cast(value)
      value.inspect.to_s << "_koalas"
    end
  end
end

class MyClass < Attribeauty::Base
  attribute :wild_animal, :koala
end

instance = MyClass.new(wild_animal: "the_wildest_animals_are")
instance.wild_animal # => "the_wildest_animals_are_koalas"

```

Note, failing to call `inspect` on the value when casting is likely to raise an error.

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` 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 the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
