pb-go-tag-bson

Adds bson:"-" tag to XXX_ fields in .pb.go

This utility is useful if you insert structs generated from protocol buffers into MongoDB.

Note: XXX_ fields were introduced in github.com/golang/protobuf v1.1.0

Before

type Entity struct {
	Type                 string   `protobuf:"bytes,1,opt,name=type" json:"type,omitempty"`
	Id                   string   `protobuf:"bytes,2,opt,name=id" json:"id,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-"`
	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}

After

type Entity struct {
	Type                 string   `protobuf:"bytes,1,opt,name=type" json:"type,omitempty"`
	Id                   string   `protobuf:"bytes,2,opt,name=id" json:"id,omitempty"`
	XXX_NoUnkeyedLiteral struct{} `json:"-" bson:"-"`
	XXX_unrecognized     []byte   `json:"-" bson:"-"`
	XXX_sizecache        int32    `json:"-" bson:"-"`
}

Install

go get -u github.com/arkavo-com/pb-go-tag-bson
