Lappa v0.4.30
Lappa 0.4.30
Lappa is a desktop ROS2 package IDE. This release focuses on a professional first-run experience, a denser IDE workflow, reliable Docker diagnostics, and an RViz-style native simulation view.
Highlights
- First-run Welcome screen with workspace and package entry points.
- Compact VS Code-style explorer, source editor, AI chat, and live simulation layout.
- OBJ, STL, DAE, and URDF text plus 3D preview in the same editor pane.
- RViz-style grid, axes, lidar, obstacles, trajectory, and camera controls.
- Docker status for CLI, daemon, Compose, image, container health, and active ROS2 launch.
- Verified real ROS2 build and launch flow for
diff_drive_2win Docker. - PID-safe process-group shutdown with no remaining simulation nodes or zombie processes.
- Rich trajectory CSV export and a repository-aware
list-demosCLI command.

On Windows, double-click the executable to open the IDE. On Linux, mark the binary executable before launching it. Docker is optional; native simulation and package editing work without a host ROS2 installation.
Verification
- Ruff lint
- Python compile check
- Full Pytest suite
- PyInstaller Windows smoke test
- Docker Desktop build, healthcheck, ROS2 launch, status, and shutdown audit
