lua - want to call a function in main.lua from another module

Question

I want a to call a function that is defined in main.lua from a module that is required (included) in main.lua. What's the best/cleanest way to do this?

Edit:

I eventually went down the dispatch event route. That seems to be a neat way of doing it.

Answer 1

There are two options as far as I can see:

1. Define the function A first, then require() the module, and call function A there.
2. require() the module first, and have the module define a function B that calls the function A in your main file. Call function B whenever you are ready to call it (i.e. function A is defined) in your main file.

The latter seems cleaner, but that would be a matter of personal preference.
