Libmobi

C library for handling Mobipocket/Kindle (MOBI) ebook format documents. Current version supports reading and parsing functions.

There is a simple program included in the project: mobitool.c. It may serve as an example how to use the library.

What works:

• reading and parsing:
  • some older text Palmdoc formats (pdb),
  • Mobipocket files (prc, mobi),
  • newer MOBI files including KF8 format (azw, azw3),
  • Replica Print files (azw4)
• recreating source files using indices
• reconstructing references (links and embedded) in html files
• reconstructing source structure that can be fed back to kindlegen
• reconstructing dictionary markup (orth, infl tags)
• handling encrypted documents

Todo:

• writing MOBI documents
• process RESC records
• exporting to EPUB documents

Doxygen documentation:

• functions,
• structures for the raw, unparsed records metadata and data,
• structures for the parsed records metadata and data,
• enums

Source:

• on github

Installation:

$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

Usage

• single include file: #include <mobi.h>
• linker flag: -lmobi

Requirements

• compiler supporting C99
• zlib (optional, configure --with-zlib=no to use included miniz.c instead)
• libxml2 (optional, enables OPF handling, configure --with-libxml2=no to disable)
• tested with gcc (>=4.2.4), clang (llvm >=3.4), sun c (>=5.13)
• builds on Linux, MacOS X, Windows (MinGW), Solaris
• tested architectures: x86, x86-64, arm, ppc
• works cross-compiled on Kindle :)
