A VS Code extension to assist manimgl math animation development. Provides scene detection, command execution, checkpoint replay, and configuration file completion to accelerate the iteration workflow within the editor.
Features
Scene Detection — Automatically identify scene classes inheriting from Scene
CodeLens — One-click run/export entry points on scene classes and checkpoints
Command Execution — Run current scene, export video (single scene / all scenes / low-quality quick export)
Checkpoint Replay — Start running from a comment marker; code is automatically copied to clipboard, works with the interactive window
Configuration Support — Auto-create, open, syntax highlight, hover hints, and completion for custom_config.yml
Walkthrough — Guide through the complete process of cloning, installing, verifying, and creating scenes
