We now have an experimental ePub Export Add-On for Ryuzine Writer! You can now also export your Ryuzine publications to ePub 3.0 format with a couple button clicks. You’ll need at least Ryuzine Writer 0.9.6.4 and the 21KB zip archive with the add-on itself:
Once you’ve got it installed and have PHP File Operations enabled the process goes something like this:
1. Compose or Load a Ryuzine file into the rich-text editor (you don’t even need to “Build” it if you aren’t also creating one in Ryuzine format).
2. Press the [ > ] button and then the [ ePub Export ] button. The new Workspace loads.
3. Press the “Auto Fill” button to automatically populate the form with information about your publication.
4. Press the “Build” button and wait for a shiny, new ePub file to drop into your downloads folder.
Be aware that this is a version 0.1 “Alpha” release of this Add-On, so there are no guarantees. Make certain you read the “Known Issues” in the README file bundled with the Add-On. Files produced with it were tested in Azardi 19, ePubView 1.2, Adobe Digital Editions 1.7.2, and Adobe Digital Editions 2.0 on a Mac. All of the files produced could be opened, however some would occasionally, randomly crash the latter two Adobe reader apps (still investigating why). The .epub files produced are unlikely to validate but generally do not contain major errors that prevent them from being opened and read. Also be aware that rendering of EPUB 3.0 format can vary greatly from one e-reader app or device to another, meaning it is highly unlikely the ePub version of your publication will look exactly like your Ryuzine version.
Got skills and want to help improve it? We’ve set up a GitHub Repository for this Add-On at: https://github.com/ryumaru/epub-addon where you may find more recent stable and unstable versions.
UPDATE 2013-10-30 – updated to version 0.2 alpha which fixes a problem with form submission that prevented the add-on from building the epub package on servers running newer versions of PHP. To update just trash/overwrite your existing file in ~/ryuzinewriter/addons/.
UPDATE 2015-08-30 – updated to version 0.3 alpha which is compatible with the new Add-On API for Ryuzine Writer v1.0. It is included in the Ryuzine PDK download.
