Hi,

Depending on the type of system, it requires that a filesystem is present and you need to point the LUA_PATH environment variables to your USB location.

According to your example, below the module (in file_y) and program (in file_x)

file_y.lua
==========
local M = {}  -- define module table

M.func_y = function()    -- define function inside module table
   print("func_y was called")
end

return M    -- return module table

file_x.lua
==========
local file_y = require("file_y")   -- load your module

local func_x = function()
   file_y.func_y()   -- call the function in the other module
   print("func_x was called")
end

-- here is where your program starts
func_x()  -- call func_x

Your example is perfect.

I added:

 

package.path = "0:"

 

at the beginning of each file because the USB stick root, where the files

are stored, is seen as "0:".

 

By the way I get an "attempt to call a nil value" error message.

Do I have to set the LUA_PATH in a different way?

Or is there something else going wrong?

Thanks,

I.
