ROS2 devs release lint_launch for launch file debugging
New open-source tool catches ROS2 launch file errors before deployment
Open Source Robotics Foundation (OSRF) has open-sourced lint_launch, a ROS2-specific tool designed to catch common errors in launch files before they cause runtime failures. Unlike standard ROS2 launch validation which often provides vague error messages from the launch library itself, lint_launch pinpoints exact locations within complex include chains.
The tool enforces stricter parameter passing conventions than default ROS2 behavior, requiring explicit parameter declaration and passing through the include hierarchy. This makes launch files more reusable and maintainable by making data flows explicit. It can be integrated into CMake test suites or run as a standalone CLI, making it suitable for both development and CI environments where robot-specific launch files need continuous validation.
- Open Source Robotics Foundation (OSRF) released lint_launch for ROS2 launch file validation
- Catches missing parameters, executables, and invalid includes with precise error locations in complex include chains
- Available as standalone CLI or CMake test integration for CI pipeline deployment
Why It Matters
Saves robotics developers debugging time by catching launch file errors early in development and CI workflows
