This repo builds on top of the reflection capabilities in the Protobuf runtime for Go and also provides reflection APIs for gRPC as well.

Note
Version 2.0.0 is still a work in progress. It is basically feature complete, but still needs more tests for the new functionality.
You can try it out by getting a pre-release version:
go get github.com/jhump/protoreflect/[email protected]
Note that the APIs may change a little bit between now and a final v2.0.0 release. Also note that some packages in v2 still need more tests, so you may find some bugs. But that should mostly be for new functionality. If you're just trying to update your code from v1 of this repo, those packages should be rock-solid and least likely to see any further API changes.
The protoreflect package in the Protobuf Go runtime provides the Descriptor interface and implementations of it that correspond to each of the descriptor types. These types are effectively smart wrappers around the generated Protobuf types in the descriptorpb package. These wrappers make descriptors much more useful and easier to use.
This repo provides some additional packages for using and interacting with descriptors.
import "github.com/jhump/protoreflect/v2/protoprint"
The protoprint package allows for printing of descriptors to .proto source files. This is effectively the inverse of a parser/compiler (such as the protocompile package.) Combined with the protobuilder package, this is a useful tool for programmatically generating protocol buffer sources.
import "github.com/jhump/protoreflect/v2/protobuilder"
The protobuilder package allows for programmatic construction of rich descriptors. Descriptors can be constructed programmatically by creating trees of descriptor protos and using the protodesc package to link those into rich descriptors. But constructing a valid tree of descriptor protos is far from trivial.
So this package provides generous API to greatly simplify that task. It also allows for converting rich descriptors into builders, which means you can programmatically modify/tweak existing descriptors.
