The showframe 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/showframe:v0.1.0": background
#set page(paper: "a6")

#set page(background: background())
#lorem(100)

#pagebreak()

#set page(background: background(stroke: blue + 1pt))
#lorem(100)

Known issues

The following limitations are known, PRs to address them are always welcome!:

• If page.margin contains the inside or outside keys, and page.binding is set to auto, the package will currently assume an LTR document with binding on the left side. It would be correct to follow Typst and determine the binding according to the text direction.

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.
