Why does quarto_render() not propagate parameter in typst?

[silvanhi]

Description

I’m having trouble propagating parameters with quarto. If I update the yaml parameter, the file renders properly but if i call quarto_render() with execute_params() it does not. Reason why I need quarto_render() is that I have to create multiple reports with various parameter sets on the same template.

Here is my example:
test.qmd

---
title: "Title Text"
author: "Author Name"
format: 
    typst:
        output-file: test.pdf
        template-partials: 
            - typst/typst-show.typ
            - typst/typst-template.typ
params:
    test_parameter: yaml Parameter
---
Current parameter value: `r params$test_parameter``

typst-show.typ

#show: article.with(
$if(title)$
    title: "$title$",
$endif$        

$if(author)$
    author: "$author$",
$endif$

$if(params.test_parameter)$
    test_parameter: "$params.test_parameter$",
$endif$
)

typst-template.typ

#let article(
  title: "Default Title",
  author: "Default Author",
  paper: "a4",
  test_parameter: "Default Parameter",
  body
) = {
  set document(
    title: title,
    author: author
  )

  set page(
    paper: paper
  )

  // Render content
  heading(title)
  heading(author)
  text(test_parameter)

  body
}

render.R

library(quarto)

# Render the Quarto document with parameters
quarto::quarto_render(
  input = "drafts/test.qmd",
  execute_params = list(
    test_parameter = "quarto render parameter"
  )
)

Also, I observe that if I use inline-code to call parameters within body, it does not render properly. This may be due to typst but in case someone knows how to deal with that, I’d be happy as well.

This has nothing to do with the R package wrapper.
Parameters are for computations only, for everything else use variables, environment variables, or metadata (parameters are not metadata).

Also, I observe that if I use inline-code to call parameters within body, it does not render properly.

Regarding this, please provide details or open a new issue.

Regarding using parameters for execution as Pandoc's metadata to be used in document, lua filter or in template, you need to explicit pass them. This is not done automatically. You can pass them all, or some of them.
