module Agents class TwitterUserAgent < Agent include TwitterConcern cannot_receive_events! description <<-MD #{twitter_dependencies_missing if dependencies_missing?} The TwitterUserAgent follows the timeline of a specified Twitter user. To be able to use this Agent you need to authenticate with Twitter in the [Services](/services) section first. You must also provide the `username` of the Twitter user to monitor. Set `include_retweets` to `false` to not include retweets (default: `true`) Set `expected_update_period_in_days` to the maximum amount of time that you'd expect to pass between Events being created by this Agent. Set `starting_at` to the date/time (eg. `Mon Jun 02 00:38:12 +0000 2014`) you want to start receiving tweets from (default: agent's `created_at`) MD event_description <<-MD Events are the raw JSON provided by the [Twitter API](https://dev.twitter.com/docs/api/1.1/get/statuses/user_timeline).
