revealjs title slide partial

kbvernon commented 1 month ago

Bug description

If I use the default template-partial for the title slide in a revealjs presentation but make no changes to the template-partial, shouldn't it have the same formatting as a presentation that doesn't use the template-partial at all?

Steps to reproduce

test-with-partial.qmd

---
title: "Critical Role"
subtitle: "Nerdy Ass Voice Actors Playing DnD"
author: 
  - name: Nott the Brave
    affiliation: The Mighty Nein
    orcid: 0000-0002-1825-0097
  - name: Fresh Cut Grass
    affiliation: Bells' Hells
    orcid: 0000-0002-1825-0097
date: last-modified
format:
  revealjs:
    template-partials:
      - title-slide.html
---

title-slide.html

<section id="$idprefix$title-slide"$for(title-slide-attributes/pairs)$ $it.key$="$it.value$"$endfor$>
  <h1 class="title">$title$</h1>
$if(subtitle)$
  <p class="subtitle">$subtitle$</p>
$endif$
$for(author)$
  <p class="author">$author$</p>
$endfor$
$for(institute)$
  <p class="institute">$institute$</p>
$endfor$
$if(date)$
  <p class="date">$date$</p>
$endif$
</section>

Expected behavior

I would expect these to produce the same output as

test-without-partial.qmd

Actual behavior

Yaml options author.orcid and author.affiliation get dropped and formatting is removed.

For reference, I was hoping to add

github: kbvernon/my-revealjs-repo

to the yaml and then this to title-slide.html

$if(github)$
    <p>GitHub: <a href="https://github.com/$github$">$github$</a></p>
$endif$

on the assumption that there's not a better way to do this...

It should, but you need to use the right title-slide partial. Since Quarto 1.2, where this partial has been introduced, Quarto is using an improved version of title slide partials. So the exact one to provide would be

https://github.com/quarto-dev/quarto-cli/blob/main/src/resources/formats/revealjs/pandoc/title-fancy/title-slide.html

The one you provided explicitely is the default pandoc title slide

https://github.com/quarto-dev/quarto-cli/blob/main/src/resources/formats/revealjs/pandoc/title-slide.html

That is why you get a difference.

The usual one from Pandoc can be opt-in by title-slide-style: pandoc (See https://quarto.org/docs/reference/formats/presentations/revealjs.html#slides)

So if you do

I believe you will get the same output.
