Syntax Highlight Code in Keynote or Powerpoint

I came across this awesome gist explaining how to syntax highlight code in Keynote. The same trick works for Powerpoint. Mac only.

1. Install homebrew if you don’t have it already and brew install highlight.
2. highlight -O rtf myfile.ext | pbcopy to highlight code to a formatted text converter in RTF output format, and copy the result to the system clipboard.
3. Paste into Keynote or Powerpoint.

If I’ve got some code in a file called eset_pca.R:

I can simply highlight -O rtf eset_pca.R | pbcopy and then paste it right into Keynote or Powerpoint.
