Features

• Flexible URL Extraction: Extract URLs from text using regular expressions.
• Domain Parsing: Parse domains into subdomains, root domains, and top-level domains (TLDs).
• Extended URL Parsing: Extend the standard net/url package in Go with additional fields and capabilities.

Installation

To install the package, run the following command in your terminal:

go get -v -u github.com/hueristiq/hq-go-url

This command will download and install the hq-go-url package into your Go workspace, making it available for use in your projects.

Usage

Below are examples demonstrating how to use the different features of the hq-go-url package.

URL Extraction

You can extract URLs from a given text string using the Extractor. Here's a simple example:

package main

import (
    "fmt"
    hqgourl "github.com/hueristiq/hq-go-url"
    "regexp"
)

func main() {
    extr := hqgourl.NewExtractor()
    text := "Check out this website: https://example.com and send an email to info@example.com."
    
    regex := extr.CompileRegex()
    matches := regex.FindAllString(text, -1)
    
    fmt.Println("Found URLs:", matches)
}

Customizing URL Extraction

You can customize how URLs are extracted by specifying URL schemes, hosts, or providing custom regular expression patterns.

• Extract URLs with Specific Schemes (e.g., HTTP, HTTPS, FTP):

  extr := hqgourl.NewExtractor(
      hqgourl.ExtractorWithSchemePattern(`(?:https?|ftp)://`),
  )

  This configuration will extract only URLs starting with http, https, or ftp schemes.

• Extract URLs with Custom Host Patterns (e.g., example.com):

  extr := hqgourl.NewExtractor(
      hqgourl.ExtractorWithHostPattern(`(?:www\.)?example\.com`),
  )

  This setup will extract URLs that have hosts matching www.example.com or example.com.

Note

Since API is centered around regexp.Regexp, many other methods are available

Domain Parsing

The DomainParser can parse domains into their components, such as subdomains, root domains, and TLDs:

package main

import (
    "fmt"
    hqgourl "github.com/hueristiq/hq-go-url"
)

func main() {
    dp := hqgourl.NewDomainParser()

    parsedDomain := dp.Parse("subdomain.example.com")

    fmt.Printf("Subdomain: %s, Root Domain: %s, TLD: %s\n", parsedDomain.Sub, parsedDomain.Root, parsedDomain.TopLevel)
}

URL Parsing

The Parser provides an extended way to parse URLs, including additional fields like port and file extension:

package main

import (
    "fmt"
    hqgourl "github.com/hueristiq/hq-go-url"
)

func main() {
    up := hqgourl.NewParser()

    parsedURL, err := up.Parse("https://subdomain.example.com:8080/path/file.txt")
    if err != nil {
        fmt.Println("Error parsing URL:", err)

        return
    }

    fmt.Printf("Subdomain: %s\n", parsedURL.Domain.Sub)
    fmt.Printf("Root Domain: %s\n", parsedURL.Domain.Root)
    fmt.Printf("TLD: %s\n", parsedURL.Domain.TopLevel)
    fmt.Printf("Port: %d\n", parsedURL.Port)
    fmt.Printf("File Extension: %s\n", parsedURL.Extension)
}

Set a default scheme:

up := hqgourl.NewParser(hqgourl.ParserWithDefaultScheme("https"))
