Logical / Boolean Parameters passed to quarto get changed to "yes" and "no"

[marianklose]

Hi there,

thanks for the amazing CLI and wrapper package for R. I just tried to pass some logical parameters (TRUE/FALSE) from a render.R script to quarto and they got coverted to "yes" and "no". The problem itself and a possible solutions is mentioned in this stackoverflow post:

https://stackoverflow.com/questions/73571919/how-to-pass-logical-parameters-with-the-quarto-r-package-to-the-knitr-chunk-opti

Since quarto-r is only a wrapper to the CLI I assume that it is not possible to pass booleans from R via YAML to quarto CLI. Would it be feasabile to put somewhere a hint in the documentation that booleans are being converted to a character string?

Thanks for the report. This is indeed an issue because Quarto follow YAML 1.2 spec with no support for yes/no and yaml R package used by this package is following 1.1 spec with yes/no support for boolean.

cat(yaml::as.yaml(list(show_plot = TRUE, show_code = TRUE)))
#> show_plot: yes
#> show_code: yes

This is this issue
