Universe

A crossword-like game written in Typst. You should fill in letters to satisfy regular expression constraints. Currently, squares and regular hexagons are supported.

[!note] This is not a puzzle solver, but a puzzle layout builder.

It takes inspiration from a web image, which derives our standard example.

Basic Usage

We use crossregex-square and crossregex-hex to build square and hex layouts respectively. They have the same argument formats. A crossregex dispatcher function can be used for dynamic grid kind, which is compatible with version 0.1.0.

#import "@preview/crossregex:0.2.0": crossregex
// or import and use `crossregex-hex`

#crossregex(
  3,
  constraints: (
    `A.*`, `B.*`, `C.*`, `D.*`, `E.*`,
    `F.*`, `G.*`, `H.*`, `I.*`, `J.*`,
    `K.*`, `L.*`, `M.*`, `N.*`, `O.*`,
  ),
  answer: (
    "ABC",
    "DEFG",
    "HIJKL",
    "MNOP",
    "QRS",
  ),
)

#import "@preview/crossregex:0.2.0": crossregex-square

#crossregex-square(
  9,
  alphabet: regex("[0-9]"),
  constraints: (
    `.*`,
    `.*`,
    `.*`,
    `.*`,
    `.*[12]{2}8`,
