goprotoc

Go-protoc

This repo makes it easy to build Protobuf plugins. The official Protobuf runtime for Go includes a similar package, but it is in practice only useful for generating Go code. It places extra constraints on the input files that only make sense when generating Go code, and it uses a model that includes several Go-specific fields (like the Go package and import path for a file, or the Go name for an element). This has no such constraints and uses a simpler model (protoreflect.Descriptor) to provide an easy way to build plugins that generate code other than Go.

Status: Experimental

The V1 of this repo included additional APIs that are useful for generating Go code. It is effectively superseded by the newer google.golang.org/protobuf/compiler/protogen package that is now part of the Protobuf runtime for Go. The V1 also included a goprotoc binary but that was just an experiment that never reached parity with the official protoc and has not been maintained. If you're looking for a protoc replacement, take a look at buf.

What remains in this V2 may never see the light of day in a release. It is a paired down and updated versions of the V1 plugins package. It is experimental.
