1	# Edits reaching into equation objects
2
3	`lab/` holds COM reads of a disposable OneNote 2010 clone editing a copy of
4	`corpus/math-edit/native-editor-4` by hand. `before.xml` is the page as it opened and
5	`after.xml` as it ended; the rest are reads between steps.
6
7	- A mouse selection from inside `√x+1`'s root into `∛x`'s shows both objects selected
8	whole, and Backspace removes both paragraphs (`roots-deleted.xml`).
9	- From after `a₁` in `a₁+b₂` into the body of a sum ending its paragraph: the sum is taken
10	whole with the paragraph's end, so Backspace joins `a₁` to the integral below.
11	- From a fraction's numerator in `One a/b+c two` into the root of `Three √x+y four`:
12	both objects whole, leaving `One +y four`.
13	- Enter between `→` and `∞` in `lim_(n→∞) a_n` makes the limit an equation array
14	(`limit-enter.xml`).
15	- A click in "Type equation here." selects the placeholder whole; Enter leaves its
16	paragraph empty above a new one (`placeholder-enter.xml`), and typing `x` replaces it.
17	- A drag past a line's end also takes the paragraph's end: "Alpha beta", "Gamma delta"
18	selected from `Alp` to past `delta` delete to `Alpepsilon`.
19
20	`candidate/` is the output of `selections_into_equation_objects_take_them_whole` in
21	`crates/canvas/tests/links_equations.rs`: the same edits through the editor on the same
22	page, one revision each. `cold/` is a fresh OneNote 2010 read of it, whose MathML matches
23	the lab's equation for equation. `tools/test_equation_select.py` checks this without a VM.
24	Regenerate with `CANVAS_EQUATION_SELECT_EXPORT` set to a new absolute directory while
25	running the test, then cold-open it with
26	`tools/native_runner.py OUTPUT COLD --expected-pages 1 --collect-notebook --screenshots`.

1	# Print
2
3	`native/Print.one` is a section the COM API made in OneNote 2010: "Printing test", a
4	ruled page (horizontal lines every 0.2 points, as OneNote reads the XML's spacing, and a
5	margin line) with a 70-paragraph outline running past the first sheet, a picture, an
6	outline near the first sheet's foot and one reaching 867 points across; "Second page";
7	and "Wide 1200" and "Wide 560", titled pages whose one word sits that far across.
8	`native/section.pdf` is OneNote's File, Save As, PDF of the section, the same sheets File,
9	Print prints. `native/rules-section.pdf` is its PDF of `page-background/candidate`.
10
11	What they show, on a 612.36 by 790.92 point Letter sheet:
12
13	- The page prints between 36-point top and bottom margins, the margin origin at (72, 36).
14	Content reaching past the paper's right edge shrinks the whole page to fit it with 9
15	points to spare: "Printing test" prints at 0.672, "Wide 560" at 0.978, "Wide 1200" at
16	0.484.
17	- A sheet ends before the first line it would cut: the first holds paragraphs 1 to 37 and
18	the second starts at paragraph 38. Content below that on the first sheet waits for the
19	next.
20	- Rule lines print across the paper's whole width, down to the bottom margin of every
21	sheet. The page colour does not print. Template art does, and a page longer than a sheet
22	only through its art ("VeryLargeGrid") takes a second sheet.
23	- The footer, "Print Page 1", is the section's name and the sheet's number counted across
24	the whole printout, in 10-point Times New Roman centred near the paper's bottom edge; it
25	shrinks with the page towards the bottom left. No header prints; the title, date and
26	time are the page's own.
27
28	Print Preview and Settings offers Print range (Current Page, Page Group, Current Section),
29	Paper size, Scale content to paper width (on), Orientation, Footer (section and page
30	number, page number, section, none) and Start page numbering at 1. Save As, PDF offers
31	Selected Pages, Current Section and Current Notebook.
32
33	`crates/canvas/src/print.rs` checks Snowbound's sheets against these without a VM.
