║ ⬡ The fastfetch you always wanted — for ROS2 ⬡ ║
╚═════════════════════════════════════════════════════════════════════===═════╝
A beautiful, interactive Fastfetch-like system information tool and web dashboard built specifically for **ROS2 developers**.
Born from frustration. Built for roboticists.
🧠 The Genesis (aka "The Rant")
Let’s be real. We all love fastfetch. It makes us feel like elite hackers when we see that ASCII distro logo and realize we’re only idling at 400MB of RAM on our lean KDE Plasma setup. 🐧💻
But as ROS2 developers, we live in a simulation of our own creation—a simulation of multiple sourcing environments, competing DDS implementations, and the eternal mystery of "Which Domain ID am I on again?"
We looked at fastfetch and thought:
"This is great, but does it know if my TF-Luna LiDAR node is actually publishing, or if my Link Budget calculation just collapsed in a high-frequency filter failure?" 🤔💥
It didn't. And we were tired of the "Sourcing Dance":
- Open Terminal A. Source Jazzy. Run bridge.
- Open Terminal B. Source Humble. Wonder why nothing talks.
- Open Terminal C. Check
ros2 node list. Realize we aren't sourced at all. - Kernel Panic (Internal). 🤯
ROS2 Info was engineered to synthesize environmental telemetrics with live robotics runtime data. We needed a canonical "Source of Truth" that looked good enough to satisfy our terminal Rice addiction (CLI) while being accessible enough to monitor from a smartphone during hardware integration (WebUI).
We created this because Efficiency is not just about compute cycles; it's about Developer Experience (DX).
(And because looking at distro-aware ASCII art makes the wait for colcon build to finish slightly less agonizing.) 🎨
🚀 Key Features 🖥️ CLI (Fastfetch Mode) Distro-Aware ASCII Art: Automatically detects your ROS2 distro (Jazzy, Humble, Foxy, etc.) and displays a unique, stylized ASCII logo.
System & Environment Stats: OS version, CPU, Memory usage, ROS2 version, DDS middleware, and Domain ID at a glance.
Workspace Auto-Detection: Scans and displays your sourced colcon workspaces and their build status.
📊 Real-time Robotics Pulse Live Watch Mode: Instantly see active nodes, topics, services, and actions.
Interactive TUI: A built-in terminal user interface powered by click and rich to selectively view different system panels.
🌐 Web Dashboard (Inspired by ros.org) Elegant, Light-Themed Web UI: A modern dashboard that live-updates your system and ROS2 stats.
Community Integration: Seamlessly embeds the official ROS2 community blog for news and updates.
(Ensure you have sourced your ROS2 environment first: source /opt/ros/jazzy/setup.bash)
Run the command directly to print a beautiful fastfetch-style summary to your terminal:
ros2 run ros2_info ros2_infoKeep the terminal open and automatically refresh the runtime stats (nodes/topics) every 2 seconds:
ros2 run ros2_info ros2_info --watch 2Don't want to type flags? Open the interactive terminal UI to browse your system:
ros2 run ros2_info ros2_info --interactiveLaunch a rich, interactive web UI that you can view in your browser (defaults to http://localhost:8099):
ros2 run ros2_info ros2_info webros2 run ros2_info ros2_info nodes # List all active nodes
ros2 run ros2_info ros2_info topics # List all active topics
ros2 run ros2_info ros2_info packages # List installed ROS2 packages
ros2 run ros2_info ros2_info env # Show ROS2 environment variablesBuilt with Python, Click, Rich, and Flask. Designed for roboticists.
