I am working on my presentation for ChefConf. I plan to have quite a lot of code samples. I’ve found the options for getting code samples with nice syntax highlight a lackluster endeavour, with various GUI editors like TextMate, Sublime, and Atom having “Copy as RTF” plugins, but none of them being easily customizable.
So I did a quick Google search and happened on a gist I hadn’t seen before. It describes the following steps:
- Install Homebrew (done, I have that covered with Chef ;)).
- Install “highlight” with
brew install highlight.
- Use highlight to transform the source code file to RTF and copy it to the clipboard.
- Paste the clipboard into Keynote.app.
This isn’t much different than the other solutions, except one super cool thing I learned about highlight.
It has styles.

That’s right, at least at the time of this writing highlight has 82 different styles available. Including my favorite(s) solarized – both light and dark. Note that the
--help output says that this option is deprecated in the version I’ve installed (3.18_1), but the styles are in
Highlight knows the syntax highlighting for a lot of languages, these are in
/usr/local/Cellar/highlight/VERSION/share/langDefs. For example I can get my Ruby recipe highlighted with this:
This will use Courier New as the font, and depending on the theme/style used, some of the highlighting may be bold or italic. This is easy enough to change in Keynote though.
