Hello, I got some lua script
Code: 
package.path = "./Scripts/DCS-BIOS/test/compile/?.lua;" .. package.path
lfs = require("Scripts.DCS-BIOS.test.compile.lfs")
dofile([[Scripts/DCS-BIOS/BIOS.lua]])
But I need rewite it using absolut paths, my take:

Code: 
print(package.path)
package.path = "C:\\\\Users\\\\mplichta\\\\Saved Games\\\\DCS-BIOS\\\\test\\\\compile\\\\?.lua;" .. package.path
print(package.path)
lfs = require("Users.mplichta.Saved Games.DCS-BIOS.test.compile.lfs")
...
Looks like package.path is updated correctly, but I dont know how use require to load file lfs.lua from ..\test\compile\ directory, result is like (by the way I'm using lupa python libarary:
Code:

Hi there,

Can you provide a bit more regarding the purpose of your script?

So if I'm in directory were Scripts dir is, I can call:

So LocalCompile.lua orginal contet:
Code: 
-- This can be used to run the DCS-BIOS JSON generation locally without
-- starting a DCS mission
-- DCS-BIOS wiki Developer Guide have information on how to install the lua interpreter. No need to install
-- additional lua modules such as socket etc.
-- Execute => lua LocalCompile-lua or run it via VS Code task

package.path = "./Scripts/DCS-BIOS/test/compile/?.lua;" .. package.path

So if I'm in directory were Scripts dir is, I can call:
Code: 
PS C:\Users\mplichta\Projects\dcspy> dir

    Directory: C:\Users\mplichta\Projects\dcspy

Mode                 LastWriteTime         Length Name

PS C:\Users\mplichta\Projects\dcspy> lua Scripts\DCS-BIOS\test\compile\LocalCompile.lua
and it generate bunch of JSONs in Scripts\DCS-BIOS\doc\json directory
Click to expand...
Not what I was asking... let me rephrase:
What is the purpose of your script? What are you trying to accomplish?
