Thanks for the reminder to check out asciidoctor-pdf! I forgot about it because I was using macOS's default, out-of-date Ruby version for the longest time and the gem required a newer version. I've since figured out how to install and change the default Ruby installation though, so I need to check it out. It's certainly a pain getting my current workflow set up on a new machine (e.g. installing TexLive takes forever for the latex-pdf support in pandoc).
