Did ever have the need of writing a #protoc plugin and/or a #protobuf custom option?

If yes, you might have noticed that this is pretty hard and resources are scarce. In this article, I introduce how to write a small protoc plugin in #cpp and #go.

Was it easy to get every #protoc plugin executing correctly and outputting to the right place after migrating this code? No. But did I come out of it having learned valuable information about the internals of protoc that makes me a better engineer? Also no.
