• we now can select the execution order that we prefer from:

  • dependencies -> before -> perform (default, value false)
  • before -> dependencies -> perform (value true)

  just do:

  UseCase.configure do |config|
    # indicates which execution order we want
    # value false (default) selects dependencies -> before -> perform
    # value true select before -> dependencies -> perform
    config.before_depends = false
  end

• it's now possible to set accessors to attributes in context, for example instead of doing context.parameter we can just write parameter, this can be done with class methods:

  class Case < UseCase::Base
    context_reader :books
    context_writer :review
    context_accessor :comments

    def perform
      puts books # same as puts context.bookd
      self.review = 'Very good' # same as context.review = 'Very good'
      # self.comments and comments are also made available
    end
  end

• you can skip the execution flow by invoking skip!, this will interrupt the current UseCase and it's dependencies like stop!, but it will continue with the following UseCases:

  def perform
    skip! if context.to_skip
  end

• it’s possible to insert a usecase to chain using invoke!:

  def perform
    invoke! AnotherUseCase
  end

Opening pull request for discussion. Tests broken most likely because of how I persist nodes, will try to fix after knowing if the changes are good :)

PS: tests are fixed :)

@junhanamaki It would be nice if you split this pull request in 4. One for each feature.

Do you see as a good compromise to just remove the features not suited for the project, as opposed to creating more pull requests?
