Unify when-xxx filters and {{< var >}} for conditionals

[SanaeBer-03]

Description

Hello,

I’m proposing to unify the conditional behavior of the {{< var >}} macro and the when-xxx filters so that one single syntax can cover:

• Value-based checks (e.g. eq="100m")

• Numeric comparisons (gt, lt, ge, le)

• Contextual switches (format, output, engine, etc.)

Instead of maintaining separate pipelines for when-format, when-length, when-score, etc., you could write:

{{< var length eq="100m" >}}
…content shown only when length == 100 m…
{{< /var >}}

and similarly handle all other cases. Is there any plan to merge these two systems into one? Thank you!

Your are mixing two completely different things.
Filter working on Divs which is the "conditional content" and the shortcodes which are to be replaced by text.

Note that you can write your own Quarto extension to implement this but I highly suggest you don't mix syntaxes.

Additionally, please format your post using inline code and code block.

::: {.conditional-var length eq="100m"}
…content shown only when length == 100 m…
