errors with %() syntax

[stevenspiel]

I have a method:

def log_status_change
  logger %(
    foo #{bar}
  )
end

and when running yardstick 'app/**/*rb' from the command line, it returns:

ruby-2.3.1/gems/yardstick-0.9.9/lib/yardstick/parser.rb:53:in `select': undefined method `file' for nil:NilClass (NoMethodError)

So, after doing some digging, YARD::Registry.all(:method) returns an array, and for the #log_status_change method above, it returns:

[
  ...
  #<yardoc method StateMachineBase#(
      foo #{bar}
    >,
  ...
]
