Access Quarto params from R notebook

[AlbertoFabbri93]

Description

Hi, in my _quarto.yml file I have declared a variable:

params:
  save: false

The problem is that I can not find a way to access this variable from my R notebook. The canonical way to do that would be to access params$save but when I do that I get the following error:

Error in params$save : object of type 'closure' is not subsettable

If I understand it correctly, params is being overwritten by a package I am importing but I can not remove any of the imported packages. Also, accessing params as the first thing in my code does not make any difference, not sure why though.

I tried many other functions from the knitr package to access params but nothing works. How do I do it?

Thanks!

params is a document-level feature (not project-level) from knitr.

Ah okay, I missed that. So there is no way to share parameters across documents, not even using a metadata file? I read a few discussions on similar issues and there were talks about some workarounds but it doesn't seem like any of them works when including parameters, or?

That's not how Jupyter/Knitr works.
The parameter feature is single-document and document-level only, that's the limitation.

You could try using metadata instead of params, via QUARTO_EXECUTE_INFO environment variable can contains a path to a JSON with everything, see https://quarto.org/docs/advanced/quarto-execute-info.html
