Warm Reloading for maximum productivity

[44100hertz]

package.loaded.MODULE = nil enables MODULE to be required a second time, which allows us to reload files on demand.

combine this with putting xpcall inside each bind-love hook, plus an "error mode" as technomancy has implemented -- this would allow us to reload a broken file as well.

This could be taken even further, by adding a "debug mode" where we can break out of the current scene and interactively choose which files to reload when pressing F5 (thru inspecting the package.loaded table)

The watch-reload approach doesn't enable us to preserve state between reloads. In theory, this does.

Some kinds of state:

• loaded program and its data structures
• initial state changes in the code updates
• function changes in the code updates
• macro updates (if they are handled differently)
• Clearing any error handling status (when and why)
• graphics data
• sound data

Sounds like it's already been proven in existing fennel games... maybe we give it a shot, but time box it to about 2 hours of effort. After the game jam we could explore it more thoroughly
