Conditional content: Website vs. Presentation

[johannesingrisch]

Hi all,
is it possible to use conditional content not only for different output formats (e.g., html vs. pdf) but also for different document types?

Background: I am creating lecture slides (reveal js) and I want to automatically publish these as a website. On the website, I want to add additional content, which is not part of the lecture slides.

Best,

This is what "project profiles" and "conditional content" features do (see https://quarto.org/docs/projects/profiles.html and https://quarto.org/docs/authoring/conditional.html).

To have access to those features, Quarto >= 1.2 is required.

@dragonstyle I have a follow-up question: how to literally targets only html since html is an alias for everything?

---
title: Title
format:
  revealjs: default
  html: default
---

::: {.content-visible when-format="html"}

Will only appear in HTML and not in Reveal.js, but actually it appears.

:::

::: {.content-visible when-format="revealjs"}

Will only appear in Reveal.js and not in HTML or other formats.

I figure a way to do this, but it is definitely not straightforward at all.

I don't think alias should be named after formats.
In the documentation, there are formats with *, one might think of using those, but it does not work.
I would rather have an alias ends with * (e.g., html*) in its definition and to be able to use html to target the actual html format, not the type of format.

---
title: Title
format:
  revealjs: default
  html: default
---

::: {.content-visible when-format="html" unless-format="revealjs"}

Will only appear in HTML and not in Reveal.js, but actually it appears.

:::

::: {.content-visible when-format="revealjs"}

Will only appear in Reveal.js and not in HTML or other formats.

@mcanouil Is there also a way to do something like:

::: {.content-visible when-format="revealjs|beamer"}

This content is only displayed in RevealJS and/or Beamer output.

Perhaps there is a workaround for this particular case, but I am also interested in a more general approach. Perhaps a feature request if this is not already possible?

[mcanouil]

Simply had another "when-format" statement.
No need to invent syntaxes.

Note that I don't think "beamer" exists as it's actually a PDF format.

I see, thank you. I wasn't aware that that syntax would work as it was not directly clear to me from the docs. Would it be an idea to explicitly mention this and its reverse in the docs? The reverse (multiple unless-format="") also seems to work and can be quite useful too.
