Qualify the namespace for Integrations

[olleolleolle]

To get this working, I had to:

• introduce a --load option to pre-load the code (perhaps this is ready to go into the README?)
• add this PR's StateMachines:: namespacing of one line of code in the machine handler

---

# .yardopts
--load load_yard_plugins.rb
lib/**/*.rb
app/**/*.rb -

# load_yard_plugins.rb
require 'state_machines'
require 'state_machines/graphviz'
require 'state_machines/yard'

[olleolleolle]

Closing, in favor of #1.

My current load_yard_plugins.rb:

require 'state_machines'
require 'state_machines/graphviz'
require 'state_machines/yard'

#
# See: https://github.com/state-machines/state_machines-yard/pull/1

class StateMachine::YARD::Handlers::Transition
  def process
    if [StateMachines::Machine, StateMachines::Event, StateMachines::State].include?(owner.class)
      options = {}

      # Extract requirements
      ast = statement.parameters.first
      ast.children.each do |assoc|
        # Skip conditionals
        next if %w(if :if unless :unless).include?(assoc[0].jump(:ident).source)

        options[extract_requirement(assoc[0])] = extract_requirement(assoc[1])
      end

      owner.transition(options)
    end
  end
end

class StateMachine::YARD::Handlers::Machine
  def integration
    @integration ||= StateMachines::Integrations.match_ancestors(namespace.inheritance_tree(true).map { |ancestor| ancestor.path })
  end
end
