With this addon to Friendica you can give your user the possibility to post
their *public* messages to Twitter. The messages will be strapped their rich
context and shortened to 140 characters length if necessary. If shortening of
the message was performed a link will be added to the Tweet pointing to the
original message on your server.
There is a similar addon for forwarding public messages to
"StatusNet":http://status.net [[StatusNet Plugin]].

___ Requirements ___
To use this plugin you have to register your Friendica instance as an
_client application_ for Twitter with _read and write_ access, we do not intend
to use Twitter for login. The registration can be done at twitter.com/apps
and you need to have a Twitter account to do so.
After you registered the application you get an OAuth consumer key / secret
pair that identifies your app, you will need them for configuration.
The inclusion of a shorturl for the original posting in cases when the
message was longer than 140 characters requires it, that you have *PHP5+* and
*curl* on your server.
___ Where to find ___
In the Friendica git repository /addon/twitter/, this directory contains
all required PHP files (including the Twitter OAuth library [1] by Abraham
Williams, MIT licensed and the Slinky library [2] by Beau Lebens, BSD license),
a CSS file for styling of the user configuration and an image to _Sign in with
Twitter_.

___ Configuration ___
__ Global Configuration __
If you enabled an administrator account, please use the admin panel to cofigure
the Twitter reley.
To activate this addon add @twitter@ to the list of active addons in your
.htconfig.php file
$a->config['system']['addon'] = "twitter, ..."
Afterwards you need to add your OAuth consumer key / secret pair to it by
adding the following two lines
$a->config['twitter']['consumerkey'] = 'your consumer KEY here';
$a->config['twitter']['consumersecret'] = 'your consumer SECRET here';
When this is done your user can now configure their Twitter connection at
"Settings -> Plugin Settings" and enable the forwarding of their *public*
messages to Twitter.
__ User Configuration __
When the OAuth consumer informations are correctly placed into the
configuration file and a user visits the "Plugin Settings" page they can now
connect to Twitter. To do so one has to follow the _Sign in with Twitter_
button (the page will be opened in a new browser window/tab) and get a PIN from
Twitter. This PIN has to be entered on the settings page. After submitting the
PIN the plugin will get OAuth credentials identifying this user from the
Friendica account.
If this first step was successful the Twitter configuration will be changed
on the "Plugin Settings" page displaying two check boxes. One to enable/disable
the forwarding of *all public* postings to Twitter and one to clear the
personal configuration from the Twitter credentials.
