How to get all tasks & subtasks below a tag?

[davingreen]

I annotate tasks such as:

#task/today
- [] task 1
  - [] subtask 1
- [] task 2

How do I query to display all tasks with #task/today tags above the list from any file?

Alternatively, would like a way to write a single tag for a list of tasks rather than adding a tag to each task in the list. I tried this format and script, but it does not get any sub-tasks:

- [] #task/merge
  - [] task 1
    - [] subtask 1
  - [] task 2

// This note's name
const currentNoteName = dv.current().file.name

// Notes with merge tags & reference to this note
const notes = dv.pages(`#task/merge and [[${currentNoteName}]]`).filter(n => !!n.file.tasks.filter(t => t.tags.includes('#task/merge')))

const tasks = notes.map(n => n.file.tasks.array()).array().flat().filter(t => t.tags.includes('#task/merge'))

// For each note, check tasks for merge tasks
for (let note of notes) {
	const mergeTasks = note.file.tasks.array().filter(t => t.tags.includes('#task/merge') && t.text.includes(currentNoteName))
	if (mergeTasks) {
		// Link to file
		dv.paragraph(note.file.link)

		const listUnderTask = mergeTasks.map(t => t.children.map(c => c.text))
		dv.taskList(mergeTasks)
	}
}

Thank you!

Tasks in specific section

For your first example, you can't filter tasks by a tag above the tasks list. But you can use a header. For example

### tasks today
- [ ] task 1
  - [ ] subtask 1
- [ ] task 2

DQL query:

TASK
WHERE meta(section).subpath = "tasks today"

DVJS query:

dv.taskList(dv.pages().file.tasks.where(t => t.section.subpath == "tasks today"))

Tasks nested in a main task with a specific tag

For

- [ ] #task/merge
  - [ ] task 1
    - [ ] subtask 1
  - [ ] task 2

DVJS query:

dv.taskList(dv.pages('#task/merge').file.tasks.where(t => t.tags.includes("#task/merge")).children)
