This package implements facilities to create KF8-formatted MOBI and AZW3 books. We also export the raw PalmDB writer and various PalmDoc, MOBI and KF8 components as subpackages, which can be used to implement other formats that build on these standards.
This fork was created from the original to add support for vertical right-to-left text (and also vertical left-to-right text for completeness). (in addition to support for horizontal RTL which seems to be in the code, though I haven't tested it and didn't modify it's behavior in this fork). This allows this library to generate japanese azw3 ebooks with the same text orientation as in typical Japanese printed novels to enjoy them on a Kindle reader.
Also, I added ExtraHead field to Book to allow adding e.g. extra styles directly to the generated html files.
In order to get vertical RTL text, use mobi.Book's RightToLeft=true and Vertical=true:
mb := mobi.Book{
// ...
RightToLeft: true,
Vertical: true,
}In order to get emphasis markers from yomukaku work use the following for Book's
mb := mobi.Book{
// ...
ExtraHead: `
<style>
.emphasisDots {
font-weight: normal;
text-emphasis-style: dot;
-webkit-text-emphasis-style: dot;
}
</style>`
}It would probably be cleaner to introduce the necessary styles as CSS files and refer to them in each html file using Book.CSSFlows instead of this dirty yet easy hack in templating.go.
The same goes for injecting e.g. the style for emphasisDots class via ExtraHead.
- Chapters are supported but subchapters are not
- Old readers without KF8 are not supported (Kindle 1, 2 and DX)
- Books without any text content are always malformed
- Errors during template expansion result in a panic
- MobileRead Wiki
- Calibre source code for MOBI support
- Vladimir Konovalov's Golang MOBI writer
- Library of Congress on the MOBI format
Huge thanks to the authors of these resources.
