Google 'Empty' not generated with a namespace

[qnm]

I've got a protobuf which returns an Empty e.g.

syntax = "proto3";
import 'google/protobuf/empty.proto';

service Subscription {
  rpc Subscribe(Subscriptions) returns (google.protobuf.Empty);
}

However, the generated code:

   class SubscriptionService < Twirp::Service
     rpc :Subscribe, Subscriptions, Empty, :ruby_method => :subscribe
   end

Whereas it should be:

   class SubscriptionService < Twirp::Service
     rpc :Subscribe, Subscriptions, Google::Protobuf::Empty, :ruby_method => :subscribe
   end

I'm calling the generator using:

grpc_tools_ruby_protoc --ruby_out=app/rpc --twirp_ruby_out=app/rpc app/proto/*.proto

root@11768bc0a972:/# grpc_tools_ruby_protoc --version
libprotoc 3.5.1

Any ideas what I'm doing wrong?

Nothing is wrong in your definitions. The code generation simply does not support importing other message types yet. I'll see if I can add support to it.
