Use of metadata variables in code chunk

[Pierre9344]

Hello,

In the documentation, there is a page concerning the use of variables declared in the .yml file or in the document YAML field.
Is there a way to access those variables in the code chunk in a way similar to what the rmarkdown knitr package does?

If not, is there a chance that this feature would be added later?

Thank you in advance for your answer

Right now there isn't a cross language way to accomplish this, but you could use the rmarkdown syntax like

---
title: Test 123
---

## this is a test


```{r}
rmarkdown::metadata$title
```

to access document metadata and you could read the _variables.yml file directly in a code chunk as well...

So this is only for knitr engine.
How hard it would be to internally turn all metadata into some kind of "params" list (and equivalent for Python)? 🤔

@mcanouil it's in our radar, stay tuned.

FWIW, I used _variables.yml content in an unexecuted HTML code block and in a Javascript (not OJS) block for a recent map we did. It did require some HTML escaping for our specific case (displaying an iframe embed code, or copying one to the clipboard), but otherwise it worked great!
