Hello everyone  
I created a simple hot reload tool for Processing  
For details, please see the demo video and explanation in the README.

I’m currently fixing an issue where it won’t coexist with other tools that use JavaFX.  
I look forward to hearing your thoughts.

Looks interesting, but I’m curious why in the video the windows close and reopen on code change?

Thank You. Because it is restarting the process internally.  
However, reusing windows provides a better UX. (This is a problem that needs to be solved)

Ah, OK, that explains it. The term “hot reload” is usually used to mean within one process, which is what confused me. It’s an area I’m really interested in and have been working around for years so I’m always interested to see different approaches.
