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_2w in Docker.
• PID-safe process-group shutdown with no remaining simulation nodes or zombie processes.
• Rich trajectory CSV export and a repository-aware list-demos CLI 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
