The scaffolder Package

Show borders around the main text area, header and footer in Typst documents.

This may be useful to understand and debug layout issues.
The idea is similar to the LaTeX showframe
package.

Usage

#import "@preview/scaffolder:0.2.1": scaffolding
#set page(paper: "a6")

#set page(background: scaffolding())

#lorem(100)

#pagebreak()

#set page(
  background: scaffolding(stroke: blue + 1pt),
  columns: 2,
)

#lorem(100)

Feature ideas

The following are some ideas of functionality that might be added or improved
in this package:

• Further separate measuring and rendering steps in the implementation.
  This would allow to make the rendering more customizable
  e.g. like the cross markers in this related
  tex.SE question,
  or by not having contiguous lines but just rectangles around the main and
  margin text areas.
