(noun) a maker of arrows

A Typst package for drawing diagrams with arrows, built on top of CeTZ.

#arrow-diagram(cell-size: 15mm, {
	let (src, img, quo) = ((0, 1), (1, 1), (0, 0))
	node(src, $G$)
	node(img, $im f$)
	node(quo, $G slash ker(f)$)
	conn(src, img, $f$, "->")
	conn(quo, img, $tilde(f)$, "hook-->", label-side: right)
	conn(src, quo, $pi$, "->>")
})

#arrow-diagram(
	node-stroke: black,
	node-fill: blue.lighten(90%),
	node((0,0), `typst`),
	node((1,0), "A"),
	node((2,0), "B", stroke: 2pt),
	node((2,1), "C"),

	conn((0,0), (1,0), "->", bend: 15deg),
	conn((0,0), (1,0), "<-", bend: -15deg),
	conn((1,0), (2,1), "=>", bend: 20deg),
	conn((1,0), (2,0), "..>", bend: -0deg),
)

Todo

• [x] Mathematical arrow styles
• [ ] Support CeTZ arrowheads
• [ ] Allow referring to node coordinates by their content
• [ ] Support loops connecting a node to itself
• [ ] More ergonomic syntax to avoid repeating coordinates?
