rapinoe's Introduction

Rapinoe

Rapinoe helps you parse Apple Keynote files.

Primarily it's designed to help you access the simple metadata of a Keynote file: return how many slides there are, extract the slide previews baked into the file, tell you various details about the file itself on disk, and so on.

Install

First you'll need ImageMagick. If you use Homebrew, you'll be fine with a quick:

brew install imagemagick

Then install the gem:

gem install rapinoe
