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