How to properly require lua file?? (app crashes after apk packaging)

Apollo14 · October 2020

Hi guys!
I have appConfig.lua file that contains:

return {
	adTestingEnabled=false,
	forceDefaultSettings=false,
	--etc...
}

And I have this line of code in my main.lua:

APP_CONFIG=require("appConfig")

It works on gideros emulators (both PC and mobile).
BUT it crashes after packaging apk.

OMG it's so ugly, I came to know that it broke my release version for 10 days already and I didn't even know about it. App fell down in keyword rankings.
Why does working with gideros have to be so ugly?
How do we properly require such files?

You basically don’t need require with gideros, because gideros loads all your files by default unless you tell it otherwise. If you really want to require a file, you have to tell gideros your file shouldn’t be read by default by marking it ‘exclude from execution’ or —!NOEXEC.
It looks like it works in the player but in reality your file is loaded and executed twice. During export, gideros merges all lua files that have not been excluded into a single one, so require doesn’t work anymore.

Last note, always check your exported packages before pushing them to the stores. A player is close to the real thing, but has some specific code and initialization to make it communicate with the studio, obviously, and is not 100% the same as the autonomous version.

I made a change to the studio so that it renames lua files that will be merged during export when sending them to the player, that way 'require' will fail in player too.

Guys, so what is a correct way to store app settings in a separate file? (and load it in the init.lua)

As often there are many ways:
- do as you initially did, but mark your setting file ‘exclude from execution’
- Or just make its file name not ending in .lua and use dofile() to load it
- Use the dependency graph to have the settings file loaded first (I still need to check if it actually works)

Why not to use init.lua without any extra files?

Usually I have global table "Game" in init.lua with all variables.

Yes, it works, init.lua can have dependencies.

I wanna maintain several projects using one codebase but different configuration
I think "exclude from execution" will work well

I've also tried dofile("appConfig.txt"), but when we edit txt files in Gideros there's no convenient syntax highlight, editing lua-files is much more pleasant.

Just add

--!NOEXEC

at the very first line of your config file, Gideros will recognize it as no exec automatically (without using right click menu)
