Problem with require

Scouser · March 2013

@Atilim:

Looking at this thread I decided to see if I could help. I downloaded the project, loaded it into Gideros Studio and tried to run it. This is what I get:

tiled_map.lua:23: module 'maps/map01' not found:
	no field package.preload['maps/map01']
	no file 'C:\Program Files (x86)\Lua\5.1\lua\maps/map01.luac'
	no file '.\maps/map01.dll'
	no file 'C:\Program Files (x86)\Gideros\maps/map01.dll'
	no file 'C:\Program Files (x86)\Gideros\loadall.dll'
stack traceback:

It works perfectly fine on Windows XP. This machine is running Windows 7 Professional 64bit and I'm a bit puzzled as to why it cannot see the map file. Maybe you could shed some light on it.

The offending line is the map = require(filename) line in the following function

function TiledMap:init(filename)
 
	local directory = "."
 
	if string.find(filename, "/") then
		directory = string.gsub(filename, "/%w*$", "")
	end
 
	local map = require(filename)	-- Error occurs here
 
	.....
 
end

@Scouser that's quite interesting, because it seems to work on mine Windows 7 machine 32bit.
And I don't even see any issues that was mentioned in the original post, it seems to work fine for me

I remember in some post it was mentioned that there were couple of issues with require:
1) it cached results, so its better not to use it if you requiring and deleting stuff
2) you could not require files in temp or documents folders

I know this probably does not apply here, but the solution mentioned was to use dofile or loadfile. Maybe it would work?

@ar2rsawseen: The problem here is that tiled_map.lua uses require(filename). I know that dofile(filename..".lua") works but I was making @atilim aware of the problem I encountered.

This looks like a problem which could happen to other users and it would be helpful if @atilim could replicate and fix it OR maybe change the TileMap examples supplied with GiderosStudio to use dofile instead require.
