• ox-epub

Generate =.epub= files directly from OrgMode. This will export EPUB version 2, which should give broad compatibility. It should also be relatiely easy to convert the resulting =.epub= to a =.mobi= (Kindle).

** Prerequisites

This depends on Emacs 24.3 and OrgMode 9, it won't work on OrgMode 8 or any version of Emacs before 24.3.

You will also need a working version of the =zip= utility.

** Installation

If you have MELPA stable activated, it is as simple as this:

=M-x package-install RET ox-epub RET=

** Usage

See the =sample= directory for a sample of what ox-epub can do.

Hit =C-c C-e E e= to publish the current buffer to an EPUB.

There are some required export options that need to be set. These are

• =UID= a unique id of the document, otherwise known as uri, may be a url
• =DATE= the date of the document, for valid values see [[https://www.w3.org/TR/NOTE-datetime]]
• =AUTHOR= the document author or editor, the creator in the EPUB spec
• =TITLE= the document title

Furthermore there are some properties which are optional:

• =Subject= the subject matter of the book
• =Description= a description of the book
• =Publisher= the publisher of the book
• =License= the rights associated with this book, the copyright notice and further rights may be included in this option.
• =EPUBCOVER= the cover image to use for the export
• =EPUBSTYLE= the CSS file to use for the export, this is set by default but can be set on a per document basis

The only other option that is exported:

• =LANGUAGE= the language of the book, this is to be interpreted according to RFC3066 or it's succeeding documents [[https://www.ietf.org/rfc/rfc3066.txt]], no other interpretations are allowed according to the EPUB spec.

** Features

Currently =ox-epub= can do the following:

• simple cover images
• inclusion of png and jpg images
• export of mathematical formulas
• direct =.epub= generation
• add stylesheets to your liking: Use the EPUBSTYLE property to add a list of stylesheets and customize =html-head-include-default-style= to toggle inclusion of the default stylesheet.

** Caveats

• Mathematical formulas only export well if you use the =dvipng= backend. =dvipng= should be included in TeXlive.

** Coffee

I very much like coffee, so if you want to contribute to my coffee fund, you can now do that :)
