TodoList Print List

Part of TodoList to a todo product, built on task rows. A TodoList declared no capability, so the only way its work left the screen was a screenshot. Microsoft To Do's list menu answers that with Print list, and nothing more.

How it works

• The TodoList is Portable, with one export-only format: Print. ResourceDefinitionMap gives it portable, and PortableFormatMap holds its one format, so Print sits in the resource page's Export menu beside every other type's exports (resource model). The browser's print dialog also saves a PDF, so this is the list's export as much as its print.
• Print opens a dialog of toggles, as To Do's does: Print steps, on by default, and Print notes, off. The export runs from the Export menu, outside any component, so it loads the list and opens the dialog through useTodoListPrintDialogStore, keyed by the list it was opened for, as the Sheet's export opens useSheetPortableDialogStore. The toggles are the viewer's and carry to the next print. ResourceDialogsComponentMap maps the TodoList to ResourceTodoListDialogs, which mounts the edit dialog, the print dialog and the print sheet together, as ResourceSheetDialogs does.
• What prints is the list as the reader sees it: the list's name as the heading, then each open todo in the viewer's sort, through the same sortTodoListItems the Items blade draws with (importance), each after an empty circle to tick on paper, with its due date through NuxtTime. Its steps follow when that toggle is on, each ticked or not, and its notes when that one is. Completed todos follow under a Completed heading, struck through and newest first, as the section on screen does.
• The printed sheet is its own element. ResourceTodoListPrintSheet mounts only between Print and the browser's afterprint, teleported to the body and drawn hidden print:block. While it is mounted it marks the body, and a print rule hides every other child of the body, so the page prints the list and none of the app. It prints in the light scheme whatever the page's theme. The notes are the schema's already-sanitized HTML.

What is deliberately not in it

• No CSV or Markdown export yet. Portable makes either one more entry in the same map, but To Do offers neither and no one has asked for one; printing to PDF already makes a file.
• No email list. To Do reaches email only through sharing, which is the smart lists' and sharing's territory.
