Support RevealJS chalkboard

[neilernst]

I'm trying to use this with the Reveal Chalkboard plugin, but it doesn't work. Perhaps it is my config. My header looks something like:

---
title: My Title
format:
  clean-revealjs: default
  revealjs: 
    chalkboard: true
author:
  - name: Neil Ernst
date: last-modified
---

I'm guessing there is some issue in the format: key with order? I tried both clean first and last.

@neilernst place the options you want passed to revealjs under the desired format, e.g.:

---
title: My Title
format:
  clean-revealjs:
    chalkboard: true
author:
  - name: Neil Ernst
date: last-modified
---

Then, pressing c opens the chalkboard.

Thanks! where does the clean-revealjs: default go? I would guess as default it doesn't need to be stated explicitly.

[coatless]

The default component just indicates that no other revealjs options will be passed in. Since we're specifying chalkboard: true, we can no longer use the default entry. If we wanted to enable additional revealjs features, then we would need to add each new feature similar to if we were just using the revealjs format, e.g.

---
title: My Title
format:
  clean-revealjs:
    chalkboard: true
    incremental: true
author:
  - name: Neil Ernst
date: last-modified
---

If we just wanted the vanilla revealjs slides, we would have used revealjs in place of the clean-revealjs format:

format:
  revealjs:
    chalkboard: true
    incremental: true

Thanks for jumping in @coatless. I've been traveling so didn't have a chance to respond yet. (As an side: I've found myself recommending your macrtools package to several people recently. Very cool.)

@neilernst Just to add one more point, the default argument is actually redundant here. I left it in because it makes it slightly more convenient when you are switching in non-default args like chalkboard. But for a plain vanilla doc, your YAML can just as well be:

---
title: My Title
format: clean-revealjs
author:
  - name: Neil Ernst
date: last-modified
---

I might actually change the template YAML, so that this doesn't confuse others...

thanks for the help folks. I'm grateful for the work on this template - I'm changing my lecture slides to use Quarto and this template, learning as I go :)
