System Documentation

What problem does it solve?

Undo/redo systems are essential for complex interactions, but implementing reliable, mergeable undo stacks across diverse actions is error-prone and time-consuming.

Core Features & Use Cases

  • Implements an UndoRedoService that exposes deterministic undo/redo stacks, reactive state (e.g., CanUndo, CanRedo), and event-driven notifications.
  • Supports mergeable commands via IMergeableCommand to condense consecutive actions and optimize history.
  • Includes built-in commands (CompositeCommand, MoveTransformCommand, SetSettingCommand<T>, SetVolumeCommand) and a ready-to-use installer to wire the service in projects.
  • Event types include CommandExecutedEvent, UndoPerformedEvent, RedoPerformedEvent, and UndoStackClearedEvent for UI and analytics.

Quick Start

Install and wire up the UndoRedoService, implement a custom IUndoableCommand, and attach it to your action triggers via ExecuteAsync to enable undo/redo.
