protofmt

修改自 https://github.com/emicklei/proto-contrib

使用

package main

import (
	"bytes"
	"os"

	"github.com/emicklei/proto"
	"gitter.top/common/protofmt"
)

func main()  {
	def, err := os.ReadFile("testdata.proto")
	if err != nil {
		// do something
    }
	parser := proto.NewParser(bytes.NewReader(def))
	parse, err := parser.Parse()
	if err != nil {
		// do something
	}
	var buf = new(bytes.Buffer)
	protofmt.NewFormatter(buf, "    ").Format(parse)
	err = os.WriteFile("testdata.proto", buf.Bytes(), os.ModePerm)
	if err != nil {
		// do something
	}
}
