  1. Install GNU social directly under a domain (Qvitter is not compatible with subdirectory installs) with fancy urls enabled (if your instance has "index.php" in its URLs, Qvitter will not work properly) and HTTPS enabled (it's always best to use HTTPS from the beginning, there will be issues with federation if you choose to enable HTTPS later)

  2. Put all files in local/plugins/Qvitter

  3. Add addPlugin('Qvitter'); to your /config.php file.

  4. It's highly recommended to use the StoreRemoteMedia plugin. It will cache attachments from remote instances locally and make them appear in the streams. Add addPlugin('StoreRemoteMedia'); to your /config.php file. (Only available in newer GNU social)

  5. There are settings in QvitterPlugin.php, but for easy updates, put them in config.php instead. Example:

// Qvitter-settings
$config['site']['qvitter']['enabledbydefault'] = true;
$config['site']['qvitter']['defaultbackgroundcolor'] = '#f4f4f4';
$config['site']['qvitter']['defaultlinkcolor'] = '#0084B4';
$config['site']['qvitter']['timebetweenpolling'] = 5000;
$config['site']['qvitter']['urlshortenerapiurl'] = ''; // if your site is on HTTPS, use url to shortener.php here
$config['site']['qvitter']['urlshortenersignature'] = 'b6afeec983';
$config['site']['qvitter']['sitebackground'] = 'img/vagnsmossen.jpg';
$config['site']['qvitter']['favicon_path'] = Plugin::staticPath('Qvitter', '').'img/gnusocial-favicons/';
$config['site']['qvitter']['sprite'] = Plugin::staticPath('Qvitter', '').'img/sprite.png?v=40';
$config['site']['qvitter']['enablewelcometext'] = true;
// $config['site']['qvitter']['customwelcometext']['sv'] = '<h1>Välkommen till – en federerad<sup>1</sup> mikrobloggsallmänning!</h1><p>Etc etc...</p>';
// $config['site']['qvitter']['customwelcometext']['en'] = '<h1>Welcome to – a federated microblog common!</h1><p>Etc etc...</p>';
// $config['site']['qvitter']['customtermsofuse'] = 'Our custom terms of use';
$config['site']['qvitter']['blocked_ips'] = array();

// Recommended GNU social settings
$config['thumbnail']['maxsize'] = 3000; // recommended setting to get more high-res image previews
$config['profile']['delete'] = true; // twitter users are used to being able to remove their accounts
$config['profile']['changenick'] = true; // twitter users are used to being able to change their nicknames
$config['public']['localonly'] = true; // only local users in the public timeline (qvitter always has a timeline for the whole known network)
addPlugin('StoreRemoteMedia'); // makes remote images appear in the feed

The settings should be self-explanatory. In doubt, ask in the !qvitter group on, or email

  1. For better performance, disable checkschema (instructions in GNU social's config.php), but don't forget to run it when updating plugins (including Qvitter).

  2. To change the logo, edit /img/sprite.png. For easier git-updates, put it in GNU social's locale folder, and edit the sprite path setting above.


  1. Translation files reside in /locale and /doc folders.

  2. When translating .json files, don't translate the placeholder strings inside curly brackets {}


Qvitter uses GNU social's built in "twitter compatible" API. The API was designed to be compatible with Twitter's API v1.0. Some documentation is here: Twitter's API v1.1 documentation is also useful, but may be partly incorrect.

Qvitter extends this API in a few undocumented ways. See onRouterInitialized() in QvitterPlugin.php for ideas about paths for the API extensions.


Qvitter is tested with the latest GNU social nightly
