Match size of brakets

[mpmdean]

Thanks for the nice package.

If I write

$ braket(f, D^dagger , n) braket(n, D, i) $
The left and right brakets don't match

I failed to work out how to add a hidden superscript, which seems like the natural way to address this?

Hi, I'm glad that you find the package useful!

This issue is actually part of Typst itself: a symbol's attachment (superscript, subscript) can affect the symbol frame's overall height, and the bracket's height is too sensitive on the content's height - though we certainly want the bracket to be taller if the contained symbol is very tall, e.g. an integration symbol. Maybe you could consider filing an issue on https://github.com/typst/typst.

Besides, the height of lr is settable. Maybe we can add a size argument to braket?

	if args.len() <= 2 {
	$ lr(angle.l bra#h(0pt)mid(|)#h(0pt)ket angle.r) $
	} else {
	let middle = args.at(1)
	$ lr(angle.l bra#h(0pt)mid(|)#h(0pt)middle#h(0pt)mid(|)#h(0pt)ket angle.r) $
	}

//  This is NOT a full solution.
#set math.lr(size: 500%)

$ lr(angle.l D angle.r) $

Hi - that's a great idea. Feel free to open a PR:) However, I noticed Typst's lr() doesn't handle mid() well with the size parameter. I think that'd be a blocking issue:

#set math.lr(size: 500%)

$ lr(angle.l A mid(|) B angle.r), lr(angle.l A B angle.r) $

This isn't an issue with Typst, but with the font I believe. The font doesn't have constructable angle brackets, and so only has the fixed preconstructed sizes which stop at approx. 300% (33pt).

These are the 8 variants it has (sizes aren't exact, I just picked percentages that work to show the variants):

$
  stretch(|, size: #500%)
  stretch(angle.r, size: #100%)
  stretch(angle.r, size: #107%)
  stretch(angle.r, size: #112.5%)
  stretch(angle.r, size: #125%)
  stretch(angle.r, size: #150%)
  stretch(angle.r, size: #200%)
  stretch(angle.r, size: #225%)
  stretch(angle.r, size: #250%)
