{.unnumbered} messing up Typst pagebreaks

[the-solipsist]

I have a line in the template partial typst-template.typ:
show heading.where(depth: 1, outlined: true): it => { pagebreak(weak: true); it }

This works normally.

However, if my qmd document has any heading which is {.unnumbered}, then I get an error:

[typst]: Compiling UpdatedSL.typ to UpdatedSL.pdf...error: pagebreaks are not allowed inside of containers
    ┌─ UpdatedSL.typ:361:56
    │
361 │   show heading.where(depth: 1, outlined: true): it => { pagebreak(weak: true); it }
    │                                                         ^^^^^^^^^^^^^^^^^^^^^
    │
    = hint: try using a `#colbreak()` instead

Setting headings as numbering: none in the typst.template works just fine.

With this little information, it would seem that the issue is a Typst issue in your code that is unrelated to Quarto. Typst has a forum, but if you don't provide the means for others to help, it's unlikely you'll get a solution.

Did you try to modify your code as suggested by Typst?

Could you share a small self-contained "working" (reproducible) example to work with, i.e., a complete Quarto document or a Git repository? The goal is to make it as easy as possible for us to recreate your problem so that we can fix it: please help us help you! Thanks.

Sorry about that. I've provided a reproducible example below.

Modifying the pagebreak() to colbreak() as suggested by Typst subtly interferes with my page numbering code which is required to change the numbering from Roman numerals in the frontmatter to Hindu-Arabic numerals from the Introduction onwards.

For the moment I'm using this ugly kludge to get around the limitation:

  show heading.where(label: <abbreviations>)
   .or(heading.where(label: <about-this-report>))
   .or(heading.where(label: <funding>))
   .or(heading.where(label: <annex-1-policy-objectives-national-digital-government-and-governance-policy>))
   .or(heading.where(label: <annex-2-draft-policies-under-digital-government>))
   .or(heading.where(label: <annex-3-cyber-security-strategy-thrust-areas>))
   .or(heading.where(label: <annex-4>)): set heading(numbering: none)

Possibly related to this

• Typst: Unnumbered headings wrapped in extraneous block element #13212

We do our own Header creation when unnumbered is set.

This may not be necessary anymore following recent Pandoc support

• In Typst output, Quarto doesn't add identifier as label if .unlisted or .unnumbered is present as Pandoc does #13698

You're spot on!

I deleted the outer #block and used typst to compile the document and it compiled!

Thanks for confirming - this will be handled within the issues linked

Minimum working example:

test.qmd:

---
format:
  typst:
    template-partials: 
      - typst-template.typ
    keep-typ: true
---

# Heading {.unnumbered}

typst-template.typ:

#let article(
  cols: 1,
  toc_title: "Table of contents",
  toc_depth: 3,
  doc,
) = {
  // Level-1 headings start on a new page
  show heading.where(depth: 1, outlined: true): it => { pagebreak(weak: true); it }

  // the below is from the default template and is what is causing the issue:
  if cols == 1 {
    doc
  } else {
    columns(cols, doc)
  }
}

The default typst-template.typ:
