> * Live image and hot-patching is great. You edit it within the code, so if you're making a shooter game, and you're in a "draw HUD" function, you can just edit the code to be what you want and send that function to the running image, to update while you play. Any time you spot a bug, you can isolate, correct, and verify, while still running the game.

I think this is an excellent selling point. Many frameworks (e.g. JavaScript frameworks) have file system watching implemented, but it is not the same.




It is not even close to the same. And I think the point is that hot patching.

If you could save a JavaScript file and it would reload just those functions in your running app with out changing state, then that would be closer.

As far as I am aware it is near impossible in every language that isn't lisp


You can reload functions without changing state in, oh, POSIX shell.

I carefully wrote the Basta code (Bash Status Line) to be hot upgradable. https://kylheku.com/cgit/basta/about
