Curated collection of common regular expressions for Go

is

Introduction

Package is provides a curated collection of common regular expressions for Go. It aims to simplify the process of validating common patterns, such as IP addresses, URLs, email addresses, and more, using easy-to-use regular expressions.

package main

import (
  "github.com/madflojo/is"
)

func main() {
  // Validate an IPv4 address
  if is.IPv4().MatchString("10.0.0.1") {
    // do stuff
  }

  // Validate a web URL
  if is.URL().MatchString("https://example.com") {
    // do stuff
  }

  // Validate an email address
  if is.Email().MatchString("[email protected]") {
    // do stuff
  }
}

Regular expressions can be complex and challenging to create for every edge case. The goal of this project is to provide a collection that covers most common cases, while acknowledging that not all possible edge cases are addressed. Contributions and improvements to the regular expressions are always welcome to enhance the package's reliability and usefulness.
