Global in one file affects diagnostics in another

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

If I have 1.lua:

function Main()
    foobar = 1
end

and 2.lua:

function Main()
    print(foobar)
end

in the same workspace/directory.

I would expect 2.lua to show foobar as undefined (unless I explicitly require 1.lua)

Actual Behaviour

No error is shown.

Additional Notes

This might be a pecularity of how I'm using lua (each file defines a separate plugin) but I would be surprised if this is an uncommon usage pattern. At the very least there should be a way to configure the behaviour.

Also - I'd be curious to understand the thinking behind the existing behaviour?

Riproduci l’esempio nella Visual Studio Code extension con 1.lua e 2.lua nello stesso workspace, quindi traccia il modo in cui il language server condivide le variabili globali tra i file. Determina in che modo l’uso esplicito di require dovrebbe influire sulle diagnosi e se sia necessaria un’opzione di configurazione. Il lavoro è completato quando 2.lua segnala foobar come non definito, a meno che 1.lua non venga richiesto esplicitamente.
