ChatManager-Core

Incoming and outgoing lines are sorted into channels by regex patterns, for example a split for trade chat or a clan channel. Each channel appears in its own window, keeps a message history with a size limit set in the configuration, and can be shown or hidden through the settings. Mention detection flags a message that contains a player's nickname and gives it a dedicated message type with an accompanying sound.

The library is built around a programmatic API for registering custom message parsers and handlers, so other mods can extend channels and events. It intercepts the player chat and system chat packets, along with locally added client messages, and wraps them in a unified Message model with types. Long messages are split into chunks by ChatQueueManager, which bypasses the vanilla 256-character limit and sends the parts in order with a configurable delay.

Input history keeps full undo and redo stacks, with Ctrl+Z and Ctrl+Y hotkeys. Macros are named text snippets with an enable or disable toggle and a timer for repetitive chat actions. The mod requires Cloth Config API, and it is open source under the GNU General Public License v3.0 only, published for 1.21.4 and 26.2. It runs on the client only.
