Quarto VS Code extension inadvertently disables GitHub Copilot autocomplete for all other languages

[hangler]

Quarto is wonderful. However, the VS Code extension sets the following configuration rule by default:

        "github.copilot.enable": {
		"quarto": false
	}

When github.copilot.enable has a value set for any particular language, though, it implicitly disables Copilot for all non-listed languages. This is unexpected and difficult to debug.

The solution is to add a wildcard setting:

        "github.copilot.enable": {
		"quarto": false
                "*": true
	}

However, I'm not sure how to have this interact smoothly with any settings a user might already have for this configuration rule. (In my case, nothing was set before installing Quarto.)

Sorry, I just want to make sure I understand. You're claiming that this setting disabled copilot for you in all languages? I have the extension installed and can't repro (I use copilot on a daily basis):

Yes, in my case it did. Here's an example with a Remix project I just created:

That appears to be exactly what I'm running:

Did you possibly have other values set on the github.copilot.enable object in your settings before adding the "quarto": false line at all..?

Thanks for following up. It turns out that yes, I do have something very much like this on my VS Code user settings. I have no recollection of adding it (and I wish these files were stored in version control but, alas, they're not... :( ), but the following lines are present in my ~/Library/Application Support/Code/User/settings.json file:

  "github.copilot.enable": {
    "quarto": false,
    "*": true
  },

I'll say that "When github.copilot.enable has a value set for any particular language, though, it implicitly disables Copilot for all non-listed languages" smells like a VS Code bug to me. Nevertheless, it's a sufficiently bad one that we should be willing to work around it.

Adding "*": true seems intuitive, but I'd like to know how VS Code composes github.copilot.enable settings before making this change. It might just be that we want to instead remove the github.copilot.enable entry altogether.

I was just thinking exactly this myself, as I pondered it some more... setting a value specific to one language doesn't seem like it should require opting-in for all other languages! (I just tested, and changing the value to "quarto": true, but not adding the wildcard entry, has the same effect as "quarto": false).
