typst output doesn't process links from gt

[arthurgailes]

Bug description

The link below works in the gt via RStudio, but typst somehow ignores the markdown output. Thanks for you time.

Steps to reproduce

---
format: typst
---

## Quarto

Works great in GT, typst says no

```{r}
library(gt)

gt(gtcars[1:5,]) |> 
  tab_source_note(md("[google](google.com)"))
```

But it could say yes! [google](google.com)

Expected behavior

No response

Actual behavior

To be clear, gt does not emit Markdown, it emits HTML.
Use keep-md: true to see the intermediate Markdown document that is processed to Typst.

I don't know where the issue lies, but Quarto succeeds in parsing HTML tables with links, but not from your example.

Will look, since this is going through Quarto’s Typst-specific html table processing

[mcanouil]

Oh, I thought it was going through HTML > AST > Typst.

Note that the processing issue is not specific to Typst, also why I thought of the HTML table parsing to AST (or maybe a gt issue).
Sorry, to not have make this clearer.

I believe it is gt issue. The encoded part in data-qmd-base64 is HTML content and not markdown content

> rawToChar(base64enc::base64decode("PGEgaHJlZj0iZ29vZ2xlLmNvbSI+Z29vZ2xlPC9hPg=="))
[1] "<a href=\"google.com\">google</a>"

It should be [google](google.com) so that Quarto renders it to the right format through pandoc.

This is a gt issue.

And I think this is the same as what I found in there

• rendering a gt table with typst in R quarto #11610 (comment)

gt is applying some markdown conversion before passing it to quarto (rstudio/gt@31c1632/R/quarto.R#L33-L41 (blame)). This seems not right, because then markdown seems to be converted to HTML before being encoded for quarto.

Oh, I thought it was going through HTML > AST > Typst.

For Typst only, it's HTML > juice html > AST > Typst, which is why I always get concerned when gt-Typst issues come up. (But I should test first.)
