36 /* Twitter Plugin for Friendica
38 * Author: Tobias Diekershoff
39 * tobias.diekershoff@gmx.net
41 * License:3-clause BSD license
44 * To use this plugin you need a OAuth Consumer key pair (key & secret)
45 * you can get it from Twitter at https://twitter.com/apps
47 * Register your Friendica site as "Client" application with "Read & Write" access
48 * we do not need "Twitter as login". When you've registered the app you get the
49 * OAuth Consumer key and secret pair for your application/site.
51 * Add this key pair to your global .htconfig.php or use the admin panel.
53 * $a->config['twitter']['consumerkey'] = 'your consumer_key here';
54 * $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
56 * To activate the plugin itself add it to the $a->config['system']['addon']
57 * setting. After this, your user can configure their Twitter account settings
58 * from "Settings -> Plugin Settings".
60 * Requirements: PHP5, curl [Slinky library]
