Splatter

Expand constructor arguments to instance variables base on splat.

This was inspired by Gourmet Service Objects, but to use without Virtus.

Usage

Splatter::Init

class AcceptInvite
  include Splatter::Init

  splat :invite, :user

  def call
    @invite.accept!(@user)
    UserMailer.invite_accepted(invite).deliver
  end
end

AcceptInvite.new(invite, user).call

Splatter::Service

class AcceptInvite
  include Splatter::Init
  include Splatter::Service

  splat :invite, :user

  def call
    @invite.accept!(@user)
    UserMailer.invite_accepted(invite).deliver
  end
end

AcceptInvite.call(invite, user)

Splatter

Use include Splatter to include both, Splatter::Init and Splatter::Service

Installation

Add this line to your application's Gemfile:

gem 'splatter'

Easy / straightforward to mock because of single #call interface.
