## Usefull things to know

Regenerate gRPC code (https://grpc.io/docs/languages/go/quickstart/#regenerate-grpc-code)

* ( cd  ~/go/src/github.com/grpc-go/cmd/protoc-gen-go-grpc/ && go install . )
*
protoc \
  --go_out=Mgrpc/service_config/service_config.proto=/internal/proto/grpc_service_config:. \
  --go-grpc_out=Mgrpc/service_config/service_config.proto=/internal/proto/grpc_service_config:. \
  --go_opt=paths=source_relative \
  --go-grpc_opt=paths=source_relative \
  cliInterface/gosdnCLI.proto
  
Generate the ygot code:

just type: go generate
