Mix XFMT
能够打印构造体嵌套指针地址外部数据的格式化库
Formatting library that can print the internal data of the nested pointer address of the struct
Github
https://github.com/mix-go/xfmt
Overview
在 Golang 中应用 fmt
打印构造体时,无奈打印指针字段外部的数据结构,导致减少 debug 难度,该库能够解决这个问题。
Installation
- 装置
go get -u github.com/mix-go/xfmt
Usage
-
反对的办法,与
fmt
零碎库完全一致Sprintf(format string, args ...interface{}) string
Sprint(args ...interface{}) string
Sprintln(args ...interface{}) string
Printf(format string, args ...interface{})
Print(args ...interface{})
Println(args ...interface{})
- 反对
Tag
疏忽某个援用字段
type Foo struct {Bar *Bar `xfmt:"-"`}
- 应用
蕴含指针的构造体
type Level3 struct {Name string}
type Level2 struct {
Level3 *Level3 `xfmt:"-"`
Name string
}
type Level1 struct {
Name string
Level2 *Level2
Level2_1 *Level2
}
创立变量
l3 := Level3{Name: "Level3"}
l2 := Level2{Name: "Level2", Level3: &l3}
l1 := Level1{Name: "Level1", Level2: &l2, Level2_1: &l2}
打印比照
fmt
打印
fmt.Println(fmt.Sprintf("%+v", l1))
{Name:Level1 Level2:0xc00009c500 Level2_1:0xc00009c500}
xfmt
打印:其中 Level3 被定义的 tag 疏忽,Level2_1 因为和 Level2 是同一个指针因而前面的疏忽解决
fmt.Println(xfmt.Sprintf("%+v", l1))
{Name:Level1 Level2:0xc00009c500:&{Level3:0xc00007f030 Name:Level2} Level2_1:0xc00009c500}
