A method in Golang to generate random strings and copy them to the paste board

Some time ago in my life, I occasionally needed to rename some files, and it was a random name, just

It started with a manual renaming and typing a bunch of alphanumeric characters on the keyboard, but after a while it became a bit of a hassle, so I figured out if I could use golang to do this and automatically convert the generated strings

Copy to the paste board and generate the exe file with a double click. Just do it.

I did some research on the Internet and wrote about it.

Install the necessary libraries

go get github.com/atotto/clipboard

Code implementation

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)
  // Copy contents to clipboard 
  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()
}

I'm just randomly generating 10 characters here, but you can change it yourself.

Finally, the exe file is generated. When you want to use it, double-click 1 and you have it in your paste board.
