iOS - How can i pass launch args to main.lua?

Solar2D Native builds
#1

The docs says that “willLoadMain” method execute before main.lua will be called.

so, i want to pass some data as an argument table, like a product version, sandbox or debug bool values, etc.

is the any way can i perform it?

or, maybe i could set table in _G from this point? its fine too.

If I remember correctly, all you need to do to get launch arguments is to put the following line of code in your main.lua.

local launchArgs = ...

I think that the only way you can pass those launchArgs was via URLs or notifications, but it’s been such a long while that things may have changed.

#3

this part is familiar to me, the question is how to put the lua table in those args.

maybe it has some function like Corona::Lua::DispatchRuntimeEvent(L, …); which i can call from AppCoronaDelegate file.

it probably must have one.

#4

I am probably misunderstanding what you mean, but you can add tables to it in main.lua via

local launchArgs = { ... } launchArgs.myTable = {}

If you want to include some extra data to the launchArgs before main.lua, then you’ll probably need to dig into Corona source. As far as I remember, only way to get anything to launchArgs is by starting a Corona app via notifications or via URL.

#5

so, for now i find out how to set table in _G and use it.

here is piece of my code 

lua\_newtable(L); lua\_setglobal(L, "\_CONST"); lua\_getfield(L, LUA\_GLOBALSINDEX, "\_CONST"); for ( NSString \*key in constants ){ if ( [constants[key] isKindOfClass:[NSString class]] ){ const char \*var = [constants[key] UTF8String]; lua\_pushstring(L, var); lua\_setfield(L, -2, [key UTF8String] ); } if ( [constants[key] isKindOfClass:[NSNumber class]] ){ lua\_pushnumber(L, [constants[key] intValue]); lua\_setfield(L, -2, [key UTF8String] ); } } lua\_pushboolean(L, (isProduction) ? 1 : 0 ); lua\_setfield(L, -2, "PRODUCTION" ); lua\_pop(L, 1);

but anyway, if the solution with launch args will appear, please, let me know.
