Highlighted code syntax in Keynote

Do you want to display some code in a Keynote presentation?

It's easy. All you need is Homebrew installed.

First you need to install the program highlight.

$ brew install highlight

So you have a piece of code. For example some Python code. The take that snippet of code and save it to a file like code.py. Now all you need to do is run this:

$ highlight -O rtf code.py | pbcopy

Then, switch back into Keynote and simply paste.

But if you don't want to create a file of the snippet, simply copy the snippet from within your editor and run this:

$ pbpaste | highlight -S py -O rtf | pbcopy

The -S py means "syntax is py (for python)".

You can use highlight for a bunch of other things like creating HTML. See man highlight for more tips.
