Deciders

Deciders are flags to enable/disable specific features inside TweetDeck. Said features are usually near production-ready.

Location

You can get all deciders using TD.decider.getAll().

The returned object includes all deciders as keys and their status as boolean value. Like this

{
  "abuse_emergency_filter_info": true,
  "account_settings_join_team_flow": true,
  "account_settings_redesign": true,
  "action_favorited_retweet": true,
  /* ... more keys ... */
  "windows_migration_logged_in_2": true,
  "windows_migration_logged_out_2": true,
  "windows_migration_warning_2": true,
}

Override

You can override deciders in several ways.

The first one, courtesy of @NO_BOOT_DEVICE, consists of wrapping one of TD.decider methods to specifically modify specific keys when getting the deciders from TweetDeck's backend.

window.decider_override = {
  "hearts_and_likes2": true,   // revert likes to favorites
  "dm_rounded_avatars": false, // make avatars in dms nonround
  "simplified_replies": false  // remove "Replying to" replacing mentions
};

TD.decider.updateFromBackend = _.wrap(TD.decider.updateFromBackend, (function(func, dict) {
  for (var a in window.decider_override) { dict[a] = window.decider_override[a]; }
  return func(dict);
}));

TD.decider.updateForGuestId();

The other, simpler, uses the decider_overlay in TD.config (probably used for debugging purposes).

TD.config.decider_overlay = {
  "hearts_and_likes2": true,
  "dm_rounded_avatars": false,
  "simplified_replies": false
};

Notice

To avoid any issues (broke templates/features), the deciders should be changed as soon as TD is defined.
