protoc-gen-marshal-zap is a protoc plugin to generate code that implements zapcore.ObjectMarshaler interface (uber-go/zap) to the protoc message.
- Go compiler and tools
- protoc compiler
- protoc-gen-go
See https://github.com/protocolbuffers/protobuf-go
go install github.com/kei2100/protoc-gen-marshal-zap/plugin/protoc-gen-marshal-zap@latest
Define your proto file
syntax = "proto3";
package simple;
// If you want to use "marshal_zap.mask" option, import "marshal-zap.proto"
import "marshal-zap.proto";
message SimpleMessage {
string message = 1;
string secret_message = 2 [(marshal_zap.mask) = true];
}
Generate the code
protoc -I. -I$(go env GOPATH)/src/github.com/kei2100/protoc-gen-marshal-zap --go_out=. --marshal-zap_out=. simple.proto
Output results should be:
simple.pb.go # auto-generated by protoc-gen-go
simple.pb.marshal-zap.go # auto-generated by protoc-gen-marshal-zap
simple.proto # original proto file
simple_marshal_zap.pb.go
is generated as follows
// Code generated by protoc-gen-marshal-zap. DO NOT EDIT.
// source: simple.proto
package simple
import (
"go.uber.org/zap/zapcore"
)
func (x *SimpleMessage) MarshalLogObject(enc zapcore.ObjectEncoder) error {
if x == nil {
return nil
}
enc.AddString("message", x.Message)
enc.AddString("secret_message", "[MASKED]")
return nil
}
Compile marshal-zap.proto
$ make proto
Run tests
