r2s

r2s is a Text User Interface (TUI) for interacting with various aspects of a ROS 2 system. It is intended as a supplement to the ros2cli suite of command line tools.

r2s is written in Python and utilizes Textual for building the UI.

Roadmap

Currently, there are 2 primary widgets for visualizing information in a grid or as a stream of text logs.

  • ROS 2
    • Visualize stream of ROS messages in the text log view (ros2 topic echo)
    • Visualize stream of ROS logs from a node (rosconsole)
    • Visualize system load of individual nodes (requires instrumentation to associate PID with node)
    • Publish messages on a topic (ros2 topic pub)
    • Advance lifecycle node states (ros2 lifecycle)
    • Visualize message definitions (ros2 interface)
    • Call Services (ros2 service)
  • Colcon
    • List packages in a workspace (colon list/colcon graph)
    • Select and build multiple packages
    • View package build logs
    • View test logs
  • Gazebo
    • Visualize topics/nodes
    • Port ROS functionality to gz-transport and gz-msgs
