Morph

Morph is simple tools that helps you work with protoc stub and struct, where you can convert protoc stub to struct, or otherwise, save your time by copying all attribute data, except (Objects, Slices, Array) to target struct or protoc.

Installation

1. Required go installed on your machine

go version

2. Get morph

go get -u github.com/xoxoist/morph

3. Import morph

import "github.com/xoxoist/morph"

Quick Start

package main

import (
	"fmt"
	"github.com/xoxoist/morph"
	"github.com/xoxoist/morph/example/model"
	pb "github.com/xoxoist/morph/example/protobuf"
)

func sampleStructToProtoc() *pb.Todo {
	var todoProtocBlank = &pb.Todo{}
	todoStruct := model.Todo{
		ID:            "5b9e1416-1f06-4a61-a30a-0dcff164639b",
		Name:          "Lloyd",
		Completed:     true,
		NumberCode:    129520,
		NumberProduct: 25983578228,
		Codes:         []model.Code{{1}, {4}, {9}},
	}

	for _, c := range todoStruct.Codes {
		todoCodeProtocBlank := &pb.Code{}
		morph.Struct(&c).Protoc(todoCodeProtocBlank)
		todoProtocBlank.Codes = append(todoProtocBlank.Codes, todoCodeProtocBlank)
	}

	return todoProtocBlank
}

func sampleProtocToStruct(todoProtoc *pb.Todo) model.Todo {
	var todo model.Todo
	morph.Protoc(todoProtoc).Struct(&todo)

	for _, i := range todoProtoc.Codes {
		var code model.Code
		morph.Protoc(i).Struct(&code)
		todo.Codes = append(todo.Codes, code)
	}

	return todo
}

func main() {
	todoProtoc := sampleStructToProtoc()
	fmt.Println(fmt.Sprintf("protoc : %+v", todoProtoc))
	todoStruct := sampleProtocToStruct(todoProtoc)
	fmt.Println(fmt.Sprintf("struct : %+v", todoStruct))
}

API Examples

Conversion

• morph.Struct(v interface{}) morph.ProtocTransformed

  // blank protoc
  var todoProtocBlank = &pb.Todo{}
  todoStruct := model.Todo{
      ID:            "5b9e1416-1f06-4a61-a30a-0dcff164639b",
      Name:          "Lloyd",
      Completed:     true,
      NumberCode:    129520,
      NumberProduct: 25983578228,
  }
  // binds all struct attributes to protoc attributes
  morph.Struct(&todoStruct).Protoc(todoProtocBlank)

• morph.Protoc(v interface{}) morph.StructTransformed

  // blank struct
  var todo model.Todo
  todoProtoc := &pb.Todo{
      Id:            "5b9e1416-1f06-4a61-a30a-0dcff164639b",
      Name:          "Lloyd",
      Completed:     true,
      NumberCode:    129520,
      NumberProduct: 25983578228,
  }
  // binds all protoc attributes to struct attributes
  morph.Protoc(todoProtoc).Struct(&todo)
