decgen

Introduction

decgen can generate boilerplate code to handle

• tracing requests using opentrace,
• manage database/sql transactions,
• create adapters to use generated grpc servers as clients,
• protect the methods on a struct with a mutex,

decgen primarily works by generating implementations of interfaces that utilize other implementations of those interfaces.

usage

Downloading decgen is done using go get.

go get github.com/robbert229/decgen

trace

To use decgen to generate a decorator first you need to create your interface.

type Service interface {
    Do(ctx, *Request) (*Response, error)
}

decgen -i Service -s TracingService -o ./tracer.go -t trace .
