Hey Open Robotics folks 👋

So I built a small tool called **ros2\_info**.  
The idea was simple: _what if `fastfetch`, but for your entire ROS2 environment?_

One command → instant snapshot of everything happening in your ROS2 setup.

**What it shows:**  
• ROS2 distro + whether it’s LTS or nearing EOL  
• Live nodes, topics, services, and actions  
• Auto-detects which DDS middleware you’re running  
• All detected colcon workspaces + their build status  
• Installed ROS2 packages grouped by category  
• System stats (CPU, RAM, Disk)  
• Pending ROS2-related `apt` updates  
• A small web dashboard at **localhost:8099**

Basically the stuff I kept checking with 10 different commands… now in one place 😅

Works across ROS2 distros: **Foxy → Humble → Iron → Jazzy → Rolling**

**Install**

```auto
cd ~/ros2_ws/src
git clone https://github.com/zang7777/ros2_info.git
cd ~/ros2_ws && colcon build --symlink-install
source install/setup.bash
(best recommended) ros2 run ros2_info ros2_info --interactive
or just
ros2 run ros2_info ros2_info 

```

Always fun building little dev tools for the ecosystem 🤖

This looks useful! Could you please share a sample CLI output for quick evaluation?
