Text threading and image wrap-around for Typst.

meander provides a core function reflow to segment a page and wrap content around images.

See the documentation.

Quick start

The function meander.reflow splits the input sequence into

• obstacles: all objects created via the function placed (which is like place),
• containers: produced by container, optionally specifying an alignment and dimensions,
• flowing content: produced by content.

#import "@preview/meander:0.2.0"

#let my-img-1 = box(width: 7cm, height: 7cm, fill: orange)
#let my-img-2 = box(width: 5cm, height: 3cm, fill: blue)
#let my-img-3 = box(width: 8cm, height: 4cm, fill: green)
#let my-img-4 = box(width: 5cm, height: 5cm, fill: red)
#let my-img-5 = box(width: 4cm, height: 3cm, fill: yellow)

#meander.reflow({
  import meander: *

  // As many obstacles as you want
  placed(top + left, my-img-1)
  placed(top + right, my-img-2)
  placed(horizon + right, my-img-3)
  placed(bottom + left, my-img-4)
  placed(bottom + left, dx: 32%,
         my-img-5)

  // The container wraps around all
  container()
  content[
    #set par(justify: true)
    #lorem(600)
  ]
})

Use multiple containers to produce layouts in columns.

#import "@preview/meander:0.2.0"

#let my-img-1 = box(width: 7cm, height: 7cm, fill: orange)
#let my-img-2 = box(width: 5cm, height: 3cm, fill: blue)
#let my-img-3 = box(width: 8cm, height: 4cm, fill: green)

#meander.reflow({
  import meander: *

  placed(bottom + right, my-img-1)
  placed(center + horizon, my-img-2)
  placed(top + right, my-img-3)

  // With two containers we can
  // emulate two columns.
  container(width: 55%)
  container(align: right, width: 40%)
  content[#lorem(600)]
})

Meander allows precise control over the boundaries of obstacles, to draw complex paragraph shapes.

#import "@preview/meander:0.2.0"

#meander.reflow({
  import meander: *

  placed(
    center + horizon,
    boundary:
      // Override the default margin
      contour.margin(1cm) +
      // Then redraw the shape as a grid
      contour.grid(
        // 25 vertical and horizontal subdivisions (choose whatever looks good)
        div: 25,
        // Equation for a circle of center (0.5, 0.5) and radius 0.5
        (x, y) => calc.pow(2 * x - 1, 2) + calc.pow(2 * y - 1, 2) <= 1
      ),
    // Underlying object
    circle(radius: 3cm, fill: yellow),
  )

  container(width: 48%)
  container(align: right, width: 48%)
  content[
    #set par(justify: true)
    #lorem(600)
  ]
})
