How do I add paramters to the footer of the PDF when rendering the quarto document of format typst

[Prav14]

Description

Hi,
I would like to add the parameters I passed to the quarto document in the footer of the rendered document. I using typst to render the PDF. I tried using r params$text_label and also {{ < meta params.text_label > } } but unable to get the parameter value into the footer.

Code to render the quarto document
quarto::quarto_render("test_app_pdf1.qmd",execute_params=list(text_label="This is PDF generation test."))

quarto document code

title: "Test Parametes in footer"
params:
text_label: " "
format:
typst:
include-in-header:
text: |
#set page(footer: [This is a footer; r params$text_label])

This is a Quarto Test

I was wondering if there was another way to add the parameters to the footer of the PDF or if anyone could help to debug if I missed something in the above code.

I am using Quarto 1.4

Thank you!

Could you properly format your code to be usable? Thank you.

You can share a self-contained "working" (reproducible) Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).
See https://quarto.org/bug-reports.html#small-is-beautiful-aim-for-a-single-document-with-10-lines.

If you have multiple files (and if it is absolutely required to have multiple files), please share as a Git repository.

````qmd
---
title: "Reproducible Quarto Document"
format: html
engine: knitr

This is a reproducible Quarto document using `format: html`.
It is written in Markdown and contains embedded R code.
When you run the code, it will produce a plot.

```{r}
plot(cars)
```

Additionally and if not already given, please share the output of quarto check within a code blocks (i.e., using three backticks ```txt), see https://quarto.org/bug-reports.html#check.

Sure!
Code to render the quarto document
quarto::quarto_render("test_app_pdf1.qmd",execute_params=list(text_label="This is PDF generation test."))

Thanks.
I meant to edit your original post mostly.

You cannot do what you are trying to do.
Inline code in YAML is kind of a legacy of knitr.

Here is a Quarto workaround/approach:

---
title: "Test Parametes in footer"
params: 
  text_label: "In the qmd"
format:
  typst:
    include-in-header: 
      text: |
        #set page(footer: [This is a footer; {{< meta params.text_label >}}])
---

# This is a Quarto Test

Thanks for the reply. I actually tried this. But the problem I see when I use this is - it prints the parameter value from the quarto document (In the qmd) not the parameter value I pass when I render the quarto document (This is PDF generation test).

Below is the code I use to render the document.
quarto::quarto_render("test_app_pdf1.qmd",execute_params=list(text_label="This is PDF generation test."))

I don't think you can do what you want.

You can use metadata instead (it's available to the R wrapper package, see https://quarto-dev.github.io/quarto-r/reference/quarto_render.html).

quarto render index.qmd --metadata text_label:"oh no"

---
title: "Test Parametes in footer"
text_label: "In the qmd"
format:
  typst:
    include-in-header: 
      text: |
        #set page(footer: [This is a footer; {{< meta text_label >}}])
