How to render raw code with specified format in Quarto?

Description

Hello there,
I'm running Quarto version 1.8.22 in Ubuntu 22.04 and have an issue with rendering certain formats of raw code in a qmd file. This issue occurs independent of the IDE, i.e. in Positron (2025.10.1 build 4), VSCodium (1.103.25610) and RStudio (2025.05.1+513).

In my case Quarto does render raw code in html format but not in typst (or latex) format.

Here is my reprex:

---
title: reprex
format: html
---

# Lorem ipsum

This is raw code with typst attribute:
```{=typst} 
#set text(fill: red)
This text is red.
```

This is the same raw code without a pandoc attribute:
``` 
#set text(fill: red)
This text is red.
```

This is raw code with html attribute:
```{=html}
<iframe src="https://quarto.org/" width="500" height="400"></iframe>
```

This is the rendered html I get:

Why in my case does Quarto rendering have a problem with pandoc attributes typst (and latex)?

Thanks in advance!
Greb

What are you trying to do? I'm almost certain you misunderstood what a raw block is. In particular you seem to confuse raw block with code block.

Typst code has no meaning in HTML and other formats (non Typst).
Same for other raw blocks.

I suggest to read again the documentation about source code and raw content.

Thanks, @mcanouil

In particular you seem to confuse raw block with code block.

That was indeed my problem.
