/* 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]
|
|
*
