Create slideshows and give high quality presentations.

* Portable slides

Produce high quality presentations that work anywhere with =HTML/JS= using [[https://revealjs.com][Reveal.js]][fn:1]. Achieve integration inside of Emacs with [[https://github.com/hexmode/ox-reveal][ox-reveal]][fn:2]. Configure it to use a =CDN= producing presentations that are not dependent on locally installed software. An important caveat here is that paths to images must be absolute URLs.

#+begin_src emacs-lisp
(use-package ox-reveal
  :after ox
  :custom (org-reveal-root "https://cdn.jsdelivr.net/npm/reveal.js"))
#+end_src

** Capture template

When using the [[file:writing.org][Writing]] module, add a capture template for quickly creating slide presentations with the desired markup and configuration already applied.

#+begin_src emacs-lisp
(with-eval-after-load 'org-roam
  (add-to-list 'org-roam-capture-templates
               '("s" "Slides" plain (function org-roam-capture--get-point)
                 "%?"
                 :file-name "docs/slides/${slug}"
                 :unnarrowed t
                 :head
