Simple messaging system.

An implementation of the Chatops-RPC Protocol client

chats is a drop-in gem to add chat messaging to your Rails app. It implements a real-time messaging engine for Ruby on Rails 8+ apps: direct messages (DMs), group chats, image attachments, emoji reactions, read receipts, unread badges, and typing indicators. All rendered server-side and updated live with Hotwire (Turbo Streams over Action Cable), so it ships with zero custom JavaScript build steps and works with importmaps out of the box. Any model can converse via a single `acts_as_messager` macro (users, organizations, support agents — participants are polymorphic), conversations can be optionally attached to any domain record via `acts_as_chat_subject` (so users can chat about a specific order, a listing, a booking), and the whole inbox UI is overridable view-by-view like Devise. It exposes small adapter seams a blocked-users lookup, a `can_message` policy, and a notifier hook; so it snaps onto the `moderate` gem for Trust & Safety (report/block/filter, DSA + app-store compliance) and onto any notification system (like the `noticed` gem) without any hard dependencies. Messages support soft deletion, editing, system messages posted by your app, per-sender rate limiting, and optional encryption at rest.

Adds a chat functionality to any Rails 3 application. Send chat messages to online users within your application like any gmail/facebook chat. It assumes that you are using devise gem and user model as devise model for login.

ChatWorkTo can transfer ChatWork messages via notifier.

Calls a callback regularly and notifies when it returns true
