Quarto rendering trouble with Pandoc

[AlbertRapp]

I run into trouble rendering Quarto files inside Positron when this requires Pandoc. For example, this can happen when trying to render Rmd pagedown files. I'm always switching to RStudio to render in these cases.

I suspect that this happens because the RSTUDIO_PANDOC env-variable isn't available. But the way I understand #3856, this env-variable should be available when rendering Rmd or Qmd files. But this isn't the case for me.

When I render a Quarto file that looks like this:

---
title: "Untitled"
format: html
---

```{r}
Sys.getenv('RSTUDIO_PANDOC')
```

I get a "" output for the Sys.getenv() call. Am I doing something wrong here?

What gesture are you using to render the Rmd pagedown files? The change you referenced makes the variable available specifically when performing an R Markdown render task:

But it doesn't set RSTUDIO_PANDOC for ordinary terminals. I've opened #7700 to get that tracked.

Ahh didn't know that one has to render it specifically with this command. I thought Quarto will always (when available) render .Rmd files with R Markdown.
