Linkst

Introduction

Linkst is a Typst package for drawing knots in knot theory.
Since the package is new, formal documentation is limited.
For examples of all available features, check the example files:
examples/node.typ, examples/edge.typ, and examples/knot.typ

// Example of drawing a trefoil knot:

#let trefoil = knot(
  node(0, 0, connect: ((0, 1), (2, 3, true))),
  node(2, 0, connect: ((0, 1, true), (2, 3))),
  node(1, calc.sqrt(3), connect: ((0, 3, true), (1, 2))),
  
  edge(0, 1, bezier-rel: (0, 0.2), stroke: red),
  edge(2, 0, bezier-rel: ((-0.7, 1), (0.7, 1),), stroke: red),
  edge(2, 0, bezier-rel: (0, 0.2), stroke: blue),
  edge(1, 2, bezier-rel: ((-0.7, 1), (0.7, 1),), stroke: blue),
  edge(1, 2, bezier-rel: (0, 0.2), stroke: green),
  edge(0, 1, bezier-rel: ((-0.7, 1), (0.7, 1),), stroke: green),

  style: (
    stroke: 3pt,
    scale: 0.8,
    bridge-space: 0.6,
    transform: ((-1, -calc.sqrt(3) / 3),),
  )
