  • Import the package:
#import "@preview/mastermind:0.1.0": *
  • Create the list of classes:
#let classes = (
  animal: class(
    (0, 0),
    "Animal",
    type: "interface",
    attributes: ("+age: int", "+gender: String"),
    methods: ("+isMammal()", "+mate()"),
  ),
  // ...
)
  • Create the list of relationships:
#let relationships = (
  inheritance(classes.animal, classes.duck),
  // ...
)
  • Draw the diagram:
#draw-class-diagram(classes, relationships, themes.default)

Available relationships:

  • inheritance
  • implementation
  • association
  • dependency
  • aggregation
  • composition
