Issues with Citations and Pandoc

[maurerle]

Explain the problem.
I am using a markdown file with bibliography and convert to a revealjs presentation:
pandoc -s --bibliography biblio.bib --citeproc CITATIONS -t revealjs -o example24a.html

as taken from the examples (except for revealjs).

This presents some issues:

1. references are not split across multiple pages if needed
   • of course this is not the case with normal bullet points either, but you can't edit this for references?
   • this should also be fixed for beamer output
2. links are not clickable, even with link-citations: true
   • this works properly with beamer output, but not with revealjs

I would suggest to create an option of citation-presentation-count to have only 3 references per page?
Any other suggestion? Currently the references are not really usable for presentations (beamer and revealjs) with more than 3 sources listed.
But I'd really love to have this integrated.

Pandoc version?
What version of pandoc are you using, on what OS?

pandoc 2.18 on Debian 11

I solved this issue for my use case by adding the following to my style.css for revealjs:

.references {
  font-size: 0.5em;
  text-align: left;
}

Might be helpful for others.
Yet a more general solution is still needed, as this only fits my 10ish sources and is not very generic

The solution for beamer is to put the class allowframebreaks on your references slide:

# References {#refs .allowframebreaks}

[jgm]

I don't know if there is anything like allowframebreaks for reveal.js, but if so that could be a solution to 1.

I'm not sure about 2 -- link-citations ought to work in reveal.js. Looks like there's a bug, we're getting links that look like

href="#/ref-foo_1938"

instead of

href="#ref-foo_1938"

Hm, looks like that code is there intentionally in the HTML writer:

                        let s' = case T.uncons s of       
                                   Just ('#',xs) -> let prefix = if slideVariant == RevealJsSlides
                                                             then "/"
                                                             else writerIdentifierPrefix opts                                       
                                             in  "#" <> prefix <> xs         
                                   _ -> s

See https://revealjs.com/links/
However, this doesn't seem to work in my tests. Perhaps it only works if the link is to an identifier on a section?

[jgm]

This seems to be an odd limitation in reveal.js -- you can link to a section (slide) but not to something within one. Pandoc uses a generic method when you select link-citations, and this links to the citation itself, not the references slide, so this won't work with reveal.js.

[jgm]

A more general CSS solution for the references slide is

#refs {
    height: 800px;
    overflow-y: auto !important;
}

which will give you a scroll bar.

@maurerle did you ever find a way to paginate the references?

[maurerle]

No, I either use the scrollbar or make the text on the citation slide smaller.

But at least linking to references now works properly in reveal.js :)
