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