grpc/golang with flatbuffers

[Giang Tran]

Hi!

I'm trying grpc with flatbuffer 1.4 (golang), a small test

namespace fzhello;
table HelloReq {
    message: string;
}


table HelloResp {
    response: string;
}
rpc_service FzHello {
  SayHello(HelloReq): HelloResp;
}

flatc --go --grpc fzhello/fzhello.idl

But it generate me some C++ RPC interface file instead of Go. So what should I do?

Currently, only C++ is supported. Python is being worked on, and I suggest Java & Go be next. Harsh is the one currently working on it (cc-ed).

Hi Giang!

As Wouter said, only C++ is supported yet. I'm currently working on adding support for Python. Go and Java are next. :)

OK, thank you.

Has there been some progress on this?

[Wouter van Oortmerssen]

Yes, actually Go support was just merged: https://github.com/google/flatbuffers/commit/a31ddd2bb38f719996137c9c35bc702f2abaefa5

Try it out and give us some feedback :)

I just tried it. It Works! YAY! :D

How does one define a client/server stream? Is that supported?

That's good to know :)

Streaming should be supported. As you can see in the example rpc_service, you can specify (streaming: "client") (or "server", or "bidi", or "none").
