Highlight Clipboard

highlights clipboard code for Keynote presentations

Why?

If you are presenting code, you should do this as text, as people could copy it after you share your slides. There is no option for code in Keynote, so here is a simple way to do this.

Usage

First install hightlight on your Mac using Homebrew.

# be sure to update brew
sudo brew update

# when updated install highlight
sudo brew install highlight

This could take a while. Meanwhile, you can copy the function into your ~/.profile file.

Open another shell session on Terminal.app, copy the code you want to highlight and run:

# syntax [theme] [font-size]
hc js malokai 40

The RTF result of code highlighting is now copied to your clipboard. Paste it on Keynote and voilá, color was added to your code.

PROTIP: run highlight -w to see a list of available themes.
