Dashboard Test

Expected behavior

I would expect a comma-separated list of authors when a dashboard is authored by multiple people.

For example: John Doe, Jane Doe

My use case for this is attempting to produce a dynamic "poster" presentation using the dashboard. So far I think it might work with a couple workarounds!

Actual behavior

Author names are concatenated with no punctuation. Trailing spaces which are included in the author name field are removed (which is expected), meaning at best I'd probably write a bit of javascript to capture the author field and format the author list.

Yikes, that's not a great look on our part 😬.

It seems that when Quarto sees a "fancy" author list like that, the author metadata key that is visible in the Lua filters is a plain concatenation of the author names. This happens in every format, not only in dashboards. In other formats, though, Quarto uses the fancy author list to synthesize the title block.

We'll fix this for sure, thanks for reporting!

As a temporary workaround, you can do the following:

---
title: "Test Dashboard"
author:
  - name: John Doe
    orcid: 0000-0000-0000-0000
    affilifation:
        name: My Institution
  - name: Jane Doe
    orcid: 0000-0000-0000-0001
    affilifation:
        name: My Institution
filters:
  - fix_author.lua

Dashboard Test

fix_author.lua

function Meta(meta)
  meta.author = "John Doe, Jane Doe" -- or whatever else you need
  return meta
end
