初始Golang

基本语法

main.go

package main

import(
    "fmt"
)

func main(){
    fmt.Println("Hello World")
}

Template包

Template.go

import (
	"fmt"
	"text/template"
    "os"
	"regexp"
)


func main(){
	fmt.Println("Hello Go !")
	tdata := []info{
		{"abcabcabcfsdfsdfsdf"},
		{"aaafsdgdfhergdfbdfgbdhdfgdg"},
	}
	replaceFuncMap := template.FuncMap{
		"replaceAll":replaceAll,
	}
	tmpl, err := template.New("test").Funcs(replaceFuncMap).Parse(`
	{{ range . }} 
		// {{ .Info }} 
		{{ replaceAll "(aaaa)" "1111" .Info 
		| replaceAll "(abc)" "【$1】"  
		| replaceAll "(aaa)" "【$1】"  
		}} 
	{{end}}`)
	if err != nil { panic(err) }
	err = tmpl.Execute(os.Stdout, tdata)
	if err != nil { panic(err) }

	var a string

	fmt.Scanln(&a)
	fmt.Print("input", a)
}

func replaceAll(from ,to, input string) string{
	m1 := regexp.MustCompile(from)
	 return m1.ReplaceAllString(input,to)
	// return strings.ReplaceAll(input,from ,to)
}


type info struct{
	Info string
}
