Hello, I’ve constantly found myself struggling to create a launch file when I am working on projects that require the launch of multiple nodes and launch files 😅  
This made me think of finding a tool a month ago to help with that but I didn’t find any, so I thought, why don’t I try building one!

Although it is very basic, it serves as a good starting point for me. I got busy and abandoned it but got reminded yesterday when I discovered [LaunchMap](https://discourse.openrobotics.org/t/launchmap-visualize-your-ros-2-launch-files-in-vscode/45179)!

I thought it would be worth sharing to help others. The generated launch file can be checked and verified with [LaunchMap](https://discourse.openrobotics.org/t/launchmap-visualize-your-ros-2-launch-files-in-vscode/45179)!

While this works for me, I believe there could be better ways of achieving the same or improving it. Suggestions and contributions are always welcome!

This is pretty cool. Thanks for sharing. Already starred your repo!

Food for thought, you might want to run the generated file through a linter like black or ruff to keep it nice and neat before committing to people’s robotics code base.
