前段时间在生活中偶尔需要对某些文件进行重命名，而且是随机名字，刚

开始是手动重命名然后在键盘上胡乱打一些字母数字，时间长了发现也挺麻烦的，于是想到能不能用golang实现这个功能并且自动把生成的字符串

复制到粘贴板，然后生成exe文件，要用的是直接鼠标双击就行。说干就干。

网上搜了些相关资料，于是写了出来。

安装必要的库

go get github.com/atotto/clipboard

代码实现

package main

import (
    "fmt"
    "github.com/atotto/clipboard"
    "math/rand"
    "strings"
    "time"
)

var a = [...]string{"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z",
    "1", "2", "3", "4", "5", "6", "7", "8", "9", "0"}

func main() {
    s := g()
    fmt.Println(s)
    //复制内容到剪贴板
    clipboard.WriteAll(s)
}

func g() string {
    var builder strings.Builder
    for i := 0; i < 10; i++ {
        rand.Seed(time.Now().UnixNano())
        time.Sleep(1 * time.Nanosecond)
        c := rand.Intn(36)
        builder.WriteString(a[c])
    }
    return builder.String()
}

我这里是随机生成10个字符，你也可以自己改。

最后生成了exe文件，要用的时候双击一下，你的粘贴板里就有了。
