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.
Writer
  • 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.
Reader
  • Can only read metadata; content is not accessible.

Usage

Writer
w, err := mobi.NewWriter("/tmp/example.mobi")
if err != nil {
	panic(err)
}
defer w.Close()

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

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

// Add chapters and subchapters
ch1 := w.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"))

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

// Output MOBI File
w.Write()
Reader
r, err := mobi.NewReader("/tmp/example.mobi")
if err != nil {
	panic(err)
}
defer r.Close()

fmt.Printf("Document type: %s\n", r.DocType())
fmt.Printf("Author(s): %s\n", strings.Join(r.Authors(), ", "))
fmt.Printf("Title: %s\n", r.BestTitle())
// See reader.go for additional record types

if r.HasCover() {
	img, _ := r.Cover()
	f, _ := os.Create("/tmp/mobi_example.jpg")
	jpeg.Encode(f, img, nil)
	f.Close()
}

func NewWriter 

func NewWriter(filename string) (writer *MobiWriter, err error)

NewWriter initializes a writer. Takes a pointer to file and book title/database name

Example 
package main

import (
	"github.com/efskap/mobi"
)

func main() {
	w, err := mobi.NewWriter("/tmp/example.mobi")
	if err != nil {
		panic(err)
	}
	defer w.Close()

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

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

	// Add chapters and subchapters
	ch1 := w.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"))

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

	// Output MOBI File
	w.Write()

}
