Decoder for a ProtocolBuffers message that produces a Go map[string]interface{}

protobuf2map

protobuf2map can decode a ProtocolBuffer marshaled message into a map[string]interface{} using its .proto definition.

This package was created to transform such messages directly to JSON without using the generated (Go) code to do the unmarshaling and marshaling. It can be used to inspect messages for quick view and debugging. Do not use this if performance is of importance.

package main

import (
		pd "github.com/emicklei/protobuf2map"
)

func main() {
	defs := pd.NewDefinitions()
	_ = defs.ReadFile("your.proto")
	protoBytes := []byte{} // your marshalled Protobuf message
	dec := pd.NewDecoder(defs, proto.NewBuffer(protoBytes))
	result, _ := dec.Decode("yours", "YourMessage")
	log.Printf("%#v",result)
}

how to compile the test

protoc --go_out=. *.proto

protobuf2map's Issues

Missing types (`uint64`)

I get this error when decoding a .proto that works elsewhere:

unknown type:uint64

Is it possible there are a few missing types?
