Parameter in Quarto Typst not working with quarto::render function

[nithinmkp]

Description

I am basically trying to do some dynamic documents using quarto and typst. but I am not able to pass colours from R code to typst.

The issue is this:
I have penguins.qmd which is parameterised. The qmd file works as expected and creates a dynamic report which has also some nice colour codes based on the input parameter. But when I use render.R to create reports for all species, everything works except the colour coding. I can’t find a way to do this. Now since i need this report for three species of penguins in my analysis, i can change my params argument in penguins.qmd to generate report. This works as expected as shown below.

The report is also colour coded. Now i can use render.R to generate all reports at once. But the issue is although some contents change when we use this approach some contents do not change. as show below

as can be seen color is still of adelie in side bar. also in header it is still adelie. I guess it is beacause of my template issues. Hope i have made my issue clear!

Parameters are for computations as already stated in your previous issue, they are not metadata, so you cannot do as --execute-param won't update the default metadata:

• https://github.com/nithinmkp/typst-paramter/blob/main/typst-show.typ#L9

So use actual metadata such as top level "species" and generate that metadata in your code.

```{r}
#| output: asis
#| echo: false
cat(sprintf("\n\n---\nspecies: %s\n---\n\n", params[["species"]]))
```

In the future, please share small example and don't use library(tidyverse) which means to install more than 100 packages for no reasons here.
The following is quite enough.

---
title: "Penguins"
format:
  typst:
    template-partials:
      - typst-show.typ
      - typst-template.typ
params:
  species: Adelie
engine: knitr
---

```{=typst}
#v(-1em)
*#text(size: 1.6em)[`{r} params[["species"]]`]*  
```

Sure! noted!. But with this how will i control the position? and also about colour?

[mcanouil]

Please try the code shared in your example.

Thanks a lot. Just one clarification. The ```{r}
#| output: asis
#| echo: false
cat(sprintf("\n\n---\nspecies: %s\n---\n\n", params[["species"]]))
