gookit/goutil/dump
– 是一个 golang 数据打印工具包,能够打印出丑陋易读的 go slice, map, struct 数据。
次要性能:
- 应用简略,间接调用
dump.P(vars...)
即可 - 反对所有的根底数据类型
- 反对 slice, map, struct 数据结构
- 反对传入打印多个变量
- 默认输入调用地位,方便使用
- 反对自定义局部能力,如 缩进,色调主题等

打印根底类型
package main
import "github.com/gookit/goutil/dump"
// rum demo:
// go run ./dump/_examples/basic_types.go
func main() {
dump.P(
nil, true,
12, int8(12), int16(12), int32(12), int64(12),
uint(22), uint8(22), uint16(22), uint32(22), uint64(22),
float32(23.78), float64(56.45),
'c', byte('d'),
"string",
)
}
输入成果:
打印 slice
打印 array, slice 都会一行一个元素输入,同时会在最初输入长度。
package main
import "github.com/gookit/goutil/dump"
// rum demo:
// go run ./dump/_examples/slice.go
func main() {
dump.P([]byte("abc"),
[]int{1, 2, 3},
[]string{"ab", "cd"},
[]interface{}{
"ab",
234,
[]int{1, 3},
[]string{"ab", "cd"},
},
)
}
输入成果:
打印 map
打印 map 数据结构,会一行一个元素输入,同时会在最初输入 map 长度。
package main
import "github.com/gookit/goutil/dump"
// rum demo:
// go run ./map.go
// go run ./dump/_examples/map.go
func main() {
dump.P(map[string]interface{}{
"key0": 123,
"key1": "value1",
"key2": []int{1, 2, 3},
"key3": map[string]string{
"k0": "v0",
"k1": "v1",
},
},
)
}
输入成果:
打印 struct
打印 struct 数据,指针类型会主动打印底层实在数据
package main
import (
"fmt"
"github.com/gookit/color"
"github.com/gookit/goutil/dump"
)
// rum demo:
// go run ./struct.go
// go run ./dump/_examples/struct.go
func main() {
s1 := &struct {cannotExport map[string]interface{}}{cannotExport: map[string]interface{}{
"key1": 12,
"key2": "abcd123",
},
}
s2 := struct {
ab string
Cd int
}{"ab", 23,}
color.Infoln("- Use fmt.Println:")
fmt.Println(s1, s2)
color.Infoln("\n- Use dump.Println:")
dump.P(
s1,
s2,
)
}
输入成果:
自定义 dumper
反对自定义 dumper 一些选项。如 缩进,色调主题等
// Options for dump vars
type Options struct {
// Output the output writer
Output io.Writer
// NoType dont show data type TODO
NoType bool
// NoColor don't with color
NoColor bool
// IndentLen width. default is 2
IndentLen int
// IndentChar default is one space
IndentChar byte
// MaxDepth for nested print
MaxDepth int
// ShowFlag for display caller position
ShowFlag int
// MoreLenNL array/slice elements length > MoreLenNL, will wrap new line
// MoreLenNL int
// CallerSkip skip for call runtime.Caller()
CallerSkip int
// ColorTheme for print result.
ColorTheme Theme
