Kirby Paperback Export

Export Kirby CMS content for use with the Paperback Book Maker.

This plugin is compatible with both Kirby 3 and Kirby 4.

What does this plugin do?

The plugin generates a lightly formatted plain text file from a set of pages specified by the user. The text file is used to create a “book” package which can be viewed on a Newton OS device.

An example of the exported file can be downloaded using the link below. The file contains all of the terms currently published on the Newton Glossary site.

What is a Paperback book, you ask?

Paperback is a simple cross-platform utility created by David Fedor that takes plain text files and quickly packages them for viewing on a Newton OS device. Since the Paperback utility only runs under classic Mac OS and Windows, an online Paperback Book Maker was developed by Victor Rehorst for all your cross-platform needs.
