Syntax highlighting code for keynote presentations

Most of my talks and lecture material over the past several years have been html5 slide decks. Syntax highlighting has been extremely easy since I parse all the code with knitr. However, I’ve had to use keynote again recently and have found it hard to insert readable code chunks. I’ve recently discovered a tool called highlight that makes things easier again.

You can install highlight using homebrew.

brew install highlight

Then highlight code from a script and copy it to your clipboard with this simple command:

highlight -O rtf <script_name>.R | pbcopy

and paste the result into a slide. voila.
