# Unwrap Shortlinks

Stable tag: 0.3.4  
Tags: urls, links, classicpress  
Tested up to: 6.6  
Contributors: Kelson  
License: GPLv2 or later

Follows shortened links (t.co, bit.ly, etc) and WordPress' ?p=123-style links, and expands them so that your blog post will point directly to the destination.

## Description

Automatically expands URLs at the following known link shorteners when you save a post:
* t.co
* bit.ly
* ow.ly
* j.mp
* is.gd
* trib.al
* buff.ly
* wp.me
* tmblr.co
* goo.gl
* dlvr.it
* fb.me
* qr.ae
* aka.ms
* tinyurl.com

## Installation

Install the plugin and activate it. The next time you paste a supported short URL into a post, it will be updated when the post is saved.

## Frequently Asked Questions

### What if the destination redirects to another link?

If the destination is another known URL shortener (ex. t.co pointing to bit.ly pointing to wp.me pointing to a blog post), it'll keep going up to 8 levels (to avoid infinite loops!) or until it gets a URL that isn't on the list. 

### How do I add a shortener to the list?

It's not supported yet, but I plan on adding an options page for it.

### I'm running on a local server and this doesn't do anything!

Most likely your system is configured to block your local webserver
from making outgoing connections. This is a sensible default for security!
Depending on your system, it may be blocked by a local or network firewall.
If you're running Fedora Workstation with SELinux (like I am), this will enable it:
```
sudo setsebool -P httpd_can_network_connect true
```

### What about compatibility?

It should work going back to the classic editor and forward to the block editor. It even works on [ClassicPress](https://www.classicpress.net/).
