Shortcode expansion inside attributes requires single quotes

[marianoibaldi]

Bug description

Hello,

I have a Quarto project with a document and an associated variables file (_variables.yml). When I try to use one of these shortcodes in the fig-scap option, it is not replaced by its associated value. Additionally, and depending on the quotes used for the content of the fig-scap option, the results are different:

• If single quotes are used, the shortcode is expressed in its original form (e.g. {{< var vars.ttx >}}).

• If double quotes are used, the reference to the figure and its caption is completely broken and so it is not appearing in the list of figures.

Steps to reproduce

I created a github repository with the minimal reproducible example:

https://github.com/marianoibaldi/figscap.git

Expected behavior

The text displayed in the list of figures should appear as: Short text TLex

Actual behavior

Unwanted behavior is highlighted in red in the figure.

This is a known issue, and you currently have to use single quotes if you want to use shortcodes in attributes. It's an ugly quirk but one we really cannot easily fix at the moment.

Thank you @cscheid! But when I use the single quotes, the result is the unprocessed shortcode (as the figure 2 in my screen capture).
Maybe I am loosing something of your explanation?
