Sharing function : Calling a function from require file

Solar2D General Questions/Discussion

Hey,
I’m trying to structure things more nicely and having my interface files on require files that load in. Now im having difficulty access/ sharing out the functions from one to another.

I can call a function that is in menu_letters.lua from the main file (menu_letters.menuOut) but what I require is to call a function from the main file in the required module… so below I need to call menuOpen in the main file from the file that is being required… like using _parent in Flash…

How is this possible?
main.lua

 super = require("menu\_letters")  
 level = super:newMain()  
  
menuOpen = function( event )  
 transition.to(btn\_menutab, { time = 500, rotation = 180 })  
end

menu_letters.lua

menuOut = function( event ) transition.to(btn\_menutab, { time = 500, rotation = 0 }) end [import]uid: 21298 topic_id: 17048 reply_id: 317048[/import]

@josh, just one little note from a development point of view.

the menu_letters.lua file is more like a library for you, right? because if that is how you look at it then there is a simple thing that I wanted to suggest.

you *never* have the library work with fixed elements/variable name, it has routines that get variable and objects passed to it to manage. this is in reference to the btn_menutab that is in your code, it is an absolute (hardcoded) variable.

if you do not look at it like a library, then you will have to look at the module(…, package.seeall) line at the start of your code. However adding that is also a choice that is up to you as there are some developers that prefer *not* to use that as it will be deprecated, no idea when, but deprecated for sure.

I use the module method and I wouldn’t worry about it for now as when the time comes, my apps might have been updated several times over by then.

cheers,
