Mobi

Writer/Reader for Mobi format.

Note: All testing were done on Kindle Previewer (Windows) and Kindle Paperwhite (6th Gen)

Before You Start

This is more or less WIP. Use at your own risk.
This package was written for a specific task, thus there are certain limitations, such as:
- img tags are ignored and not embedded.
- TOC depth does not go beyond 1. Meaning for now you can only have chapters and sub-chapters. But sub-chaper can not have it's own sub-chapters.
HTML formatting is supported, but rendering is dependant on your eBook reader. (For Kindle see Supported HTML Tags in Book Content)
Cover images should be in JPG (I have not tested GIF, which sould be supported).
- IMPORTANT: Images resized using image/jpeg package will not display (in Kindle) because JFIF APP0 marker segment is not generated by image/jpeg package.
Table of Content is automaticaly generated.

Usage

Writer

m, err := mobi.NewWriter("output.mobi")
if err != nil {
	panic(err)
}

m.Title("Book Title")
m.Compression(mobi.CompressionNone) // LZ77 compression is also possible using  mobi.CompressionPalmDoc

// Add cover image
m.AddCover("data/cover.jpg", "data/thumbnail.jpg")

// Meta data
m.NewExthRecord(mobi.EXTH_DOCTYPE, "EBOK")
m.NewExthRecord(mobi.EXTH_AUTHOR, "Book Author Name")
// See exth.go for additional EXTH record IDs

// Add chapters and subchapters
ch1 := m.NewChapter("Chapter 1", []byte("Some text here"))
ch1.AddSubChapter("Chapter 1-1", []byte("Some text here"))
ch1.AddSubChapter("Chapter 1-2", []byte("Some text here"))

m.NewChapter("Chapter 2", []byte("Some text here")).AddSubChapter("Chapter 2-1", []byte("Some text here")).AddSubChapter("Chapter 2-2", []byte("Some text here"))
m.NewChapter("Chapter 3", []byte("Some text here")).AddSubChapter("Chapter 3-1", []byte("Some text here"))
m.NewChapter("Chapter 4", []byte("Some text here")).AddSubChapter("Chapter 4-1", []byte("Some text here"))

m.Write()
