How can I use regex for input validation in Go?

You can use the regexp package in Go to create regex patterns for validating input. What specific input are you looking to validate?

I want to validate email addresses.

You can use a regex pattern like ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$ to validate email addresses. Would you like to see an example code?

Yes, please show me an example.

Here's a simple example:

package main

import (
    "fmt"
    "regexp"
)

func main() {
    email := "[email protected]"
    pattern := `^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$`
    matched, _ := regexp.MatchString(pattern, email)
    fmt.Println(matched) // Output: true
}

This will print true if the email is valid.
