Visual editor doesn't recognize formats starting with live-

[mine-cetinkaya-rundel]

For using the visual editor with live-* formats (using quarto-live), the visual editor doesn't have the same features as those for the * format.

For example, inserting columns into slides:

• format: revealjs

• format: live-revealjs

I was just curious to learn how we did detection.

quarto/apps/lsp/src/service/quarto.ts

Lines 118 to 125 in 3bd070a

	// detect reveal document
	const formats: string[] = [];
	if (isQuartoRevealDoc(code)) {
	formats.push("revealjs");
	}
	if (isQuartoDashboardDoc(code)) {
	formats.push("dashboard");
	}

quarto/packages/quarto-core/src/document.ts

Lines 112 to 138 in 3bd070a

	const kRegExYAML =
	/(^)(---[ \t]*[\r\n]+(?![ \t]*[\r\n]+)[\W\w]*?[\r\n]+(?:---|\.\.\.))([ \t]*)$/gm;
	export function isQuartoDocWithFormat(doc: Document | string, format: string) {
	if (typeof(doc) !== "string") {
	if (isQuartoDoc(doc)) {
	doc = doc.getText();
	} else {
	return false;
	}
	}
	if (doc) {
	const match = doc.match(kRegExYAML);
	if (match) {
	const yaml = match[0];
	return (
	!!yaml.match(new RegExp("^format:\\s+" + format + "\\s*$","gm")) ||
	!!yaml.match(new RegExp("^[ \\t]*" + format + ":\\s*(default)?\\s*$", "gm"))
	);
	}
	}
	return false;
	}
	export function isQuartoRevealDoc(doc: Document | string) {
	return isQuartoDocWithFormat(doc, "revealjs");
	}

Our regex will be something like ^format:\s+revealjs\s*$ so it will indeed not catch live-revealjs

Thanks for catching this !

We probably need to teach the extension about our format specification in Quarto parseFormatString() if we want to cover all the possible cases !

That's exactly what I was thinking. Ideally, the extension would be using the FormatDescription type here instead of a string, and using the same code.
