protoc-gen-jsonshim

protoc-gen-jsonshim is a plugin for protoc which generates MarshalJSON() and UnmarshalJSON() functions for .pb.go types. The implementations simply redirect to MarshalJSONPB() and UnmarshalJSONPB() respectively. This allows the types to be used with native Go JSON serialization.

Usage

Add the executable to your system's PATH, for example:

$ go install istio.io/tools/cmd/protoc-gen-golang-jsonshim

Add the jsonshim_out option to your protoc command line, for example:

$ protoc --jsonshim_out=:output/path ...
