h20tui 0.1.1

A TUI for ROS 2

ROS 2 Window Manager TUI (h20tui)

A high-performance, asynchronous Text User Interface (TUI) designed for ROS 2 Humble. This tool transforms your terminal into a tiling window manager specifically tuned for robotics development. Navigate your workspace, monitor topics, and manage multiple nodes side-by-side using pure keyboard motions.

🚀 Key Features

• Ament-Aware Fuzzy Discovery: Instantly find executables and launch files by scanning the ament_index. No more "trash" suggestions from standard bash completion.
• Tiling Workspace: Split your view into multiple independent panes to monitor topic echo, node info, and launch logs simultaneously.
• Vim-Powered Navigation: Full hjkl support for tree navigation, log scrolling, and Ctrl + h/l for lightning-fast pane switching.
• Robust Process Management: Uses Unix process groups (os.killpg) to ensure that killing a ros2 launch command actually cleans up all child nodes.
• Search-to-Select Workflow: Seamless focus transition from the fuzzy-search bar to the command tree using only the Enter key.
