Line breaks in quarto document with typst

Debugging advice: Look at intermediate files:

keep-typ: true
keep-md: true

This is valid if you produced Raw typst. Currently, you produce Markdown content that will be parsed. In Markdown linebreak is done using two spaces and a new line (Pandoc - Pandoc User’s Guide)

If you need a hard line break, put two or more spaces at the end of a line.

In the intermediate, you can see that you would produce Markdown content, that will be then converted to typst.

So you could do two spaces and a newline

(UA_string <- params$UAs |> stringr::str_replace_all(" ", "  \n"))

Otherwise, if you produce raw content, you need to use specific block or at least use correct typst. From the doc you linked, I do think you need to had newlines after the \. So I would try

```{r}
#| include: false

# Format the UA string for printing.
(UA_string <- params$UAs |> stringr::str_replace_all(" ", " \\\\\n") |> knitr::raw_block(type = "typst"))
```


## Current NKR UAs (avoids):  
`r UA_string`
  • knitr::raw_block() will ensure you are setting the content to be Raw Typst
  • using `r and not `{r} will make sure the content is not escaped. If you are already producing Markdown output, you need to either using `{r} I(<markdown_string>)` or just usual knitr (See Quarto – Inline Code)

This will produce this Markdown

```{=typst}
A:66 \
B:8,18,35,37,38,39,41,42,54,55,59,64,65,67,73,78 \
Cw:2,4,5,6,7,8,12,15,17,18 \
DR:8,11,12,13,14,17,18 \
DQ:7 \
DQA:04,05,06
```

And Same output as above.

Another variant as example

```{r}
#| include: false

# Format the UA string for printing.
(UA_string <- params$UAs |> stringr::str_replace_all(" ", " \\\\\n"))
```


## Current NKR UAs (avoids):  

```{=typst}
`{r} I(UA_string)`
```

Hope it helps understand
