hash_out

Include HashOut to your class and convert your object to a hash with the #hash_out method.

Install

Add to your Gemfile:

gem 'hash_out', '~> 0.1'

Or install it from the command line:

$ gem install hash_out

Usage

require 'hash_out'.
Include HashOut in your class.
If desired, exclude methods from #hash_out by adding exclude_from_hash_out to them.
Call #hash_out on the instance to return a hash of method names and their values.

`#hash_out` automatically excludes the following from the hash it returns:

private methods
methods that require arguments
instance methods in classes that include HashOut that wrap or otherwise call #hash_out

require 'hash_out'

class Movie
  include HashOut

  def title
    'Fire Walk With Me'
  end

  def director
    exclude_from_hash_out
    'David Lynch'
  end

  def available_instantly? catalog=TerribleStreamingService.new
    catalog.available_instantly? self
  end

  def has_actor? actor
    actors.include? actor
  end

  def chance_of_sequel? existing_sequels, strategy=FutureSequelStrategy
    strategy.new(self, existing_sequels).chance > 0.5
  end

  private

  def actors
    ['Sheryl Lee', 'David Bowie', 'Ray Wise']
  end
end

movie = Movie.new
movie.hash_out
# => {:title=>"Fire Walk With Me", :available_instantly?=>false}
