Short title YAML option for Beamer

[wklimowicz]

In some beamer themes, the title of the presentation shows up at the bottom of each slide. Some titles don't fit:

There is an option for adding a shorter title at the bottom with square brackets on \title:

\title[Short Title]{This is the long title}

This works for beamer, but also for some document classes like amsart.

This seems like a clean implementation (line breaks for clarity):

src/resources/formats/pdf/pandoc/title.tex:

\title
+$if(shorttitle)$[$shorttitle$]$endif$
{$title$$if(thanks)$\thanks{$thanks$}$endif$}

And the qmd file:

---
title: Long title
format:
  beamer:
    shorttitle: Short title
---

An easy PR but I thought I'd check here first -- any thoughts? It would only work for some LaTeX formats, and I don't know whether the YAML key should be short-title or shorttitle.

It has to be in an if Beamer statement, because the partial is not specific to Beamer.

See https://quarto.org/docs/reference/formats/pdf.html for other options.
For short, words are delimited by a dash.

Feel free to submit a PR.

Actually, looks like this is already called title-short in the ACS template: https://github.com/quarto-journals/acs/blame/main/template.qmd -- probably best to keep using that one.

In terms of the if statement, this works for some other formats aside from beamer. For example, using amsart with the same implementation as above:

---
title: This is a very long title that runs off to the side
title-short: Short title
format: 
  pdf:
    documentclass: amsart
---
# Foo
\pagebreak
# Bar

Would this justify keeping it as a more general partial?

The real question is why this was not in Pandoc's template, if it is an option used by "most" classes.

[Mgonrub]

I'm not sure what you're asking, but I'm learning to use quarto (and with jupyter notebook) and I want to apply with beamer.
I am using themes in beamer. And I use these 2 options in the YAML:
title: long title.
subtitle: and the short title

[mcanouil]

@Mgonrub are you sure you are answering the right thread?

[Mgonrub]

Hi,
I offer my humble apologies, I was just trying to help. Saying that there was another option to put titles. Here I leave an example.

De nuevo, lo siento mucho (Again, sorry so much...)...

[mcanouil]

The goal is to have the short title feature from LaTeX, not title or subtitle, i.e., no need to shorten the title everywhere, the short title will appear at the bottom while you'll have the actual and possibly long title as title on the title slide.

PS: @Mgonrub no need to apologise and thank you anyway for the suggested "trick".

@wklimowicz Was this implemented at last?

[wklimowicz]

There's an open PR in #5627. Your hack below is probably easiest for the time being.

[raffaem]

Here is a hack altough it's horrible:

title: "Placeholder, otherwise the title page would not be rendered."
header-includes:
  - \AtBeginDocument{\title[ShortTitle]{LongTitle}}
  - \AtBeginDocument{\subtitle[ShortSubTitle]{LongSubTitle}}
  - \AtBeginDocument{\author[ShortAuthor]{LongAuthor}}
  - \AtBeginDocument{\institute[ShortInstitute]{LongInstitute}}
  - \usepackage[italian]{datetime2}
  - \newcommand{\mydate}{\DTMdisplaydate{2024}{10}{09}{-1}}
  - \AtBeginDocument{\date[\DTMsetdatestyle{iso}\mydate]{\mydate}}

Credit

EDIT: Changed the hack to also include the other entries

@mcanouil can we move this into an issue?

[raffaem]

This was fixed upstream: jgm/pandoc#10248

@mcanouil Do we need to do something for it to propagate here? Or is it automatic as a new quarto version will include a pandoc that support this?

[cscheid]

We've already updated Pandoc for 1.6, and we only update Pandoc once a release. Quarto 1.7 will include this.

[mcanouil]

Please don't ping for no reason. Thank you!

Embedded version of Pandoc will be updated when it will be updated. And this will only happen after Pandoc has made a release and after testing in Quarto which happens once or twice within a release development.
