Arg returns directory path and nothing else

Hey. Maybe it's just to early in the morning for me right now but for some reason I can't get behind it:
Code: Select all
-- Conf.lua
function love.conf(t)
t.console = true
end
-- main.lua
local function foo(...)
for _,v in ipairs(arg) do
print(v)
end
end
foo("Hello", "you", 1, 2, 3)
-- Output: C:\Users\Lars\Desktop/Test
Why is the output the directory path instead of the passed variables in the foo function arguments?
Thanks for the help. (LÖVE 11.1, Atom Editor, Win10).
(I feel so stupid)

The answer lies in the fact that the vararg expression is not accessed through a variable called
arg anymore (since lua 5.1+, but even that didn't really support that), and arg in löve is a global in the main thread having the command line arguments in it.
You want to either use {...} or the select statement if you want to work with varargs.

Thanks, easiest answer you ever had to give I guess.
I didn't used it for quite some time and I can remember that this worked in the past. "Arg" is also used in the Lua PIL that is linked
in my bookmarks, maybe I should update the link.
I go back to bed! n8
