Multiline comments collapse to one line

[wa8f7192]

Hi,

I would like to know if it is possible to collapse multiline comments to one line instead of two lines?
is this something we would need to adjust from the code editor instead / we can update the grammar accordingly?

this is the code currently we have for comments

hidden terminal ML_COMMENT: /(/*[\s\S]?*/)/;
hidden terminal ML_COMMENT1: '(' -> ')';
hidden terminal SL_COMMENT: ///[^\n\r]/;

Hi, did you check if adjusting
toFoldingRange in DefaultFoldingRangeProvider does work?

See also the includeLastFoldingLine method that explicitly controls this behavior:

langium/packages/langium/src/lsp/folding-range-provider.ts

Lines 138 to 149 in 335f9a9

	protected includeLastFoldingLine(node: CstNode, kind?: string): boolean {
	if (kind === FoldingRangeKind.Comment) {
	return false;
	}
	const nodeText = node.text;
	const endChar = nodeText.charAt(nodeText.length - 1);
	if (endChar === '}' || endChar === ')' || endChar === ']') {
	return false;
	}
	return true;

@wa8f7192 You can override the class to change the behavior according to your liking.
