Global `url` variable?

Questions
1

Whats the global url variable for, and why is it empty? :confused:

2

I’m not sure what variable you are referring to. How did you come across it?

3

Even more, if a variable is ‘empty’ (or nil) in Lua, then it does not exist at all, unlike for some other languages!

Where did you encounter this?

Update: @sven and I tried it out and indeed, if you pprint (url) it show you an empty table.

We’re not sure where it originates from (yet)

Hmm, so it’s an empty global table? Iterate the globals like this:

for name,value in pairs(_G) do
  print(name)
end

I’ve never seen url before either. Strange.
