All tasks from all files that link to this file, even indirectly?

[spencercook]

This is probably too complicated but, is it possible to list all tasks in all notes that branch out from a central note? The "branches" not all the same length. The task list would live in the central note.

So far, I have this but it's obviously a long way off.

dataview task from "" where contains(file.inlinks.file.name, "CENTRAL FILE") or contains(file.outlinks.file.name, "CENTRAL FILE")

Thanks for any help-

This is a task for DataviewJS:

let page = dv.current().file.path;
let pages = new Set([page]);

let stack = [page];
while (stack.length > 0) {
	let elem = stack.pop();
	let meta = dv.page(elem);
	if (!meta) continue;

	for (let inlink of meta.file.inlinks.concat(meta.file.outlinks).array()) {
		if (pages.has(inlink.path)) continue;
		pages.add(inlink.path);
		stack.push(inlink.path);
	}
}

let data = dv.array(Array.from(pages)).map(p => dv.page(p)).where(p => !!p).file.tasks;
dv.taskList(data);

This computes all tasks in all files that are connected to the current file (both inlinks and outlinks).

Hey, thanks so much for the reply. I tried it out and got an error:

Seems some links lead to undefined pages

Hmm... I updated the script to perhaps work better in that case.
