/**
|
||||
* Slinky allows you to go back and forth between "long" and shortened URLs
|
||||
* using popular URL shortening services.
|
||||
*
|
||||
* Slinky assumes you have cURL installed and working, and requires the JSON
|
||||
* extension installed if you're working with a service that uses JSON.
|
||||
*
|
||||
* Slinky will ONLY work with PHP5+
|
||||
*
|
||||
* It supports some of the more popular services, with easy extensibility for
|
||||
* adding your own relatively easily. It defaults to using TinyURL
|
||||
* for shortening URLs. If you want to use some of the other services, you need
|
||||
* to set some configuration options before actually shortening/lengthening
|
||||
* URLs. I'd strongly suggest that you cache results using memcached, a local
|
||||
* DB or whatever to avoid having to hit APIs etc every time you encounter a
|
||||
* URL.
|
||||
*
|
||||
* Slinky supports shortening, and auto-detection (for lengthening URLs)
|
||||
* using these services:
|
||||
* - Bit.ly
|
||||
* - Tr.im
|
||||
* - TinyURL
|
||||
* - Is.Gd
|
||||
* - Fon.gs
|
||||
* - Micurl.com
|
||||
* - ur1.ca
|
||||
* - Ptiturl
|
||||
* - Tighturl
|
||||
* - 2tu.us
|
||||
* - Snipr / Snipurl / Snurl.com / Sn.im
|
||||
*
|
||||
*
|
||||
* To use Slinky:
|
||||
*
|
||||
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
||||
* - Creates a new Slinky instance, will default to using TinyURL for ->short();
|
||||
*
|
||||
* $slinky = new Slinky( 'http://dentedreality.com.au', new Slinky_Bitly() );
|
||||
* - Creates new Slinky, forces use of Bit.ly for ->short();
|
||||
*
|
||||
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
||||
* echo $slinky->short();
|
||||
* - echos the short version of http://dentedreality.com.au/ (default to TinyURL)
|
||||
*
|
||||
* $slinky = new Slinky( 'http://tinyurl.com/jw5sh' );
|
||||
* echo $slinky->long();
|
||||
* - echos out the long version of http://tinyurl.com/jw5sh (which should be http://dentedreality.com.au/)
|
||||
*
|
||||
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
||||
* echo $slinky->long();
|
||||
* - Attempts to lengthen the URL, but will not auto-detect which service it is
|
||||
* so it will just output the original URL. Useful for always attempting to
|
||||
* lengthen any URL you come across (fails gracefully)
|
||||
*
|
||||
* $slinky = new Slinky( 'http://dentedreality.com.au/' );
|
||||
* $slinky->set_cascade( array( new Slinky_Trim(), new Slinky_IsGd(), new Slinky_TinyURL() ) );
|
||||
* echo $slinky->short();
|
||||
* - Uses the powerful cascade mode to make sure that we get a short URL from
|
||||
* Tr.im, Is.Gd or TinyURL (in that order).
|
||||
*
|
||||
* See specific service class definitions below for examples of how to use them,
|
||||
* as some services allow (or require) additional properties before you can use
|
||||
* them (for authentication etc).
|
||||
*
|
||||
* To use a different service with Slinky, just create your own class and
|
||||
* extend Slinky_Service(). Make sure you implement url_is_short(), url_is_long(),
|
||||
* make_short() and make_long(). If you need to GET or POST a URL, you can use
|
||||
* ->url_get() and ->url_post(), which your class will have inherited.

/* Twitter Plugin for Friendika
|
||||
*
|

* Author: Tobias Diekershoff
|
||||
* tobias.diekershoff@gmx.net
|
||||
*
|
||||
* License:3-clause BSD license (same as Friendika)
|
||||
*
|
||||
* Configuration:
|
||||
* To use this plugin you need a OAuth Consumer key pair (key & secret)
|
||||
* you can get it from Twitter at https://twitter.com/apps
|
||||
*
|
||||
* Register your Friendika site as "Client" application with "Read & Write" access
|
||||
* we do not need "Twitter as login". When you've registered the app you get the
|
||||
* OAuth Consumer key and secret pair for your application/site.
|
||||
*
|
||||
* Add this key pair to your global .htconfig.php
|
||||
*
|
||||
* $a->config['twitter']['consumerkey'] = 'your consumer_key here';
|
||||
* $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
|
||||
*
|
||||
* To activate the plugin itself add it to the $a->config['system']['addon']
|
||||
* setting. After this, your user can configure their Twitter account settings
|
||||
* from "Settings -> Plugin Settings".
|
||||
*
|
||||
* Requirements: PHP5, curl [Slinky library]
|
||||
*
|
||||
* Documentation: http://diekershoff.homeunix.net/redmine/wiki/friendikaplugin/Twitter_Plugin
