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?

Reproduisez l’exemple dans la Visual Studio Code extension avec 1.lua et 2.lua dans le même workspace, puis suivez la manière dont le language server partage les variables globales entre les fichiers. Déterminez comment l’utilisation explicite de require devrait affecter les diagnostics et si une option de configuration est nécessaire. Le travail est terminé lorsque 2.lua signale foobar comme indéfini, sauf si 1.lua est explicitement requis.
