gotag

golang auto generate struct tag

example

run this main.go

package main

import (
	"fmt"
	tag "gotag"
)

type User struct {
	// @Tag: json bson
	UserName string
	Age      int
}

type Book struct {
	Name   string
	Author string
}

func main() {
	tag.UseFilter(tag.FilterStruct)

	tag.ParseFile("src/gotag/example2/main.go")

	// you can also parae package
	//tag.ParsePkg("src/gotag/example2/")

}

then you can see the user struct

type User struct {
	// @Tag: json bson
	UserName string `json:"user_name" bson:"user_name"`
	Age      int 	`json:"age" bson:"age"`
}

notice

1. you need write @Tag: comment on the first field of the struct
2. after the @Tag:, write you need the tag
3. see the struct user in example

extend

2. add or overloaded node's parse handle: see this
3. use middleware to filter and parse node
