Yukata

A light weight, no dependency, plain old ruby objects on steroids.

Example

require 'yukata'
require 'pp'

class Author < Yukata::Base
  attribute :name, String
end

class Book < Yukata::Base
  attribute :title,      String
  attribute :author,     Author, coerce: false
  attribute :created_at, Date,   default: -> { Date.today }, writer: false

  def author=(value)
    @author = Author.new(value.to_h)
  end
end

book = Book.new({
  title: 'Hunt For Red October',
  author: {
    name: 'Tom Clancy'
  }
})

pp book

Creating A Coercion

This library comes with a custom coercion library. It's fairly straight forward.

Yukata.coercer.register(String, URI) do |string, type|
  #
  # Maybe do some fancy string cleanup before you coerce it
  #
  URI(string)
end

Then require that coercion to make sure it's loaded and all you simply have to do now is just do the following.

require 'pp'

class Website < Yukata::Base
  attribute :uri, URI
end

website = Website.new({uri: 'http://example.com'})

pp website
