SO basically, I would like to make a multi-file program that can be put into any directory.

Thing is, it is called with loadfile so the following will not work:


fs.getDir(shell.getRunningProgram())

SO let's say I have a script like this:


--IN test.lua
write('DIR: ')
dir = read()
loadfile(fs.combine(dir, 'test.lua'), _G)()

--IN <somedir>/test.lua
dir =
  ...
print(dir)

How could I get the dir of the running file's directory instead of the shell's current path?

You can't.

loadfile completely separates the file path (including the directory) from the executable code because it creates an anonymous function.

Obviously you could pass the directory as an argument, as the program which is calling loadfile certainly knows where that is.

Ok. That sounds good I guess.

You might be able to ask the shell for the current directory, this may not be the directory of the file though.
