sample client-server pair using gRPC and Qt in Go. The server simply stores an integer. The client, when started, automatically connects to the server and, once a second, requests the next value in an incrementing counter. I made this for testing the install environment when working with gRPC and Qt together in Go, since both have a non-trivial install process.

see here to install gRPC: http://www.grpc.io/docs/quickstart/go.html and here to install Qt: https://github.com/therecipe/qt

• lib - contains the gRPC protobuf definition of our service. Our service
• defines one unary endpoint with an input message type and an output message
• type.
• lib/count.proto - the gRPC definitions, written by a human
• lib/count - the Go package containing our gRPC client and server definitions
• lib/count/count.pb.go - generated from lib/count.proto using the following protoc invokation:
  protoc -I count count.proto --go_out=plugins=grpc:count
• cmd - contains our executable programs
• cmd/count-client - a gRPC client with a Qt ui
• cmd/count-server - a gRPC server, no graphical ui
