tldextract

==========

Extract root domain, subdomain name, tld from a url, using the [IANA TLD list](https://data.iana.org/TLD/tlds-alpha-by-domain.txt).

This is a modified version of https://github.com/joeguo/tldextract which uses the [public suffix](https://www.publicsuffix.org/) list of TLDs. 

Installation

==========

Install tldextract:

```sh

go get github.com/joeguo/tldextract

```

To run unit tests, run this command  in tldextract's source directory($GOPATH/src/github.com/joeguo/tldextract):

```sh

go test

```

Example

==========

```go

package main

import (

"fmt"

"github.com/joeguo/tldextract"

)

func main() {

	urls := []string{"git+ssh://www.github.com:8443/", "http://media.forums.theregister.co.uk", "http://218.15.32.76", "http://google.com?q=cats"}

	cache := "/tmp/tld.cache"

	extract, _ := tldextract.New(cache,false)

	for _, u := range (urls) {

		result:=extract.Extract(u)

		fmt.Printf("%+v;%s\n",result,u)

	}

}

```

Output will look like:

```plain

  &{Flag:1 Sub:www Root:github Tld:com};git+ssh://www.github.com:8443/

  &{Flag:1 Sub:media.forums Root:theregister Tld:co.uk};http://media.forums.theregister.co.uk

  &{Flag:2 Sub: Root:218.15.32.76 Tld:};http://218.15.32.76

  &{Flag:1 Sub: Root:google Tld:com};http://google.com?q=cats

```
