project:
  output-dir: Slides

• Send the slides to the “Slides” directory.

format: 
  beamer:
    theme: Madrid
    colortheme: PrimaryBullets
    aspectratio: 169
    toc: false
    include-in-header: "defs_beamer.tex"
    execute:
      echo: false
      fig-width: 7
      fig-height: 3.5
      code-line-numbers: false

• format defines the format, but only when the profile is not set to book.
  • beamer produces pdf slides, using the \(\LaTeX\) beamer class. If this is unfamiliar to you, you can change this to be html slides. The code used for conditional inclusion is based on the profile, not the output format.
    • theme: Madrid is specific to the beamer class.
    • colortheme: PrimaryBullets uses my custom beamer colortheme (which also affects the theme. this is bad programming on my part, but it looks nice). If you use this, you should change the name, institution, and email in the definition!
    • aspectratio and toc (table of contents), are beamer specific settings.
    • include-in-header uses a custom \(\LaTeX\) definition file for spacing in books versus slides. See below.
    • execute makes figures the right size for 16x9 slides. It also makes echo false by default (the book uses true by default).

For include-in-header: defs_beamer.tex, I use two special commands to make sure that I can control spacing in the slides and the book separately. In slides, I want to add spacing between lists. The \lspace command is defined as \newline if the file is executed without profile --book, and it’s defined as nothing if the profile is set to book. Similarly, \pspace adds a space between paragraphs if the book is rendering to slides and does nothing for the book.
