C library for handling Mobipocket/Kindle (MOBI) ebook format documents.
Library comes with several command line tools for working with mobi ebooks. The tools source may also be used as an example on how to use the library.
- 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)
- writing back loaded documents
- metadata editing
- handling encrypted documents
- encrypting documents for use on eInk Kindles
- improve writing
- serialize rawml into raw records
- process RESC records
- functions,
- structures for the raw, unparsed records metadata and data,
- structures for the parsed records metadata and data,
- enums
[for git] $ ./autogen.sh
$ ./configure
$ make
[optionally] $ make test
$ sudo make install
On macOS, you can install via Homebrew with brew install libmobi.
- The supported way of building project is by using autotools.
- Optionally project provides basic support for CMake, Xcode and MSVC++ systems. However these alternative configurations are not covering all options of autotools project. They are also not tested and not updated regularly.
- single include file:
#include <mobi.h> - linker flag:
-lmobi - basic usage:
#include <mobi.h>
/* Initialize main MOBIData structure */
/* Must be deallocated with mobi_free() when not needed */
MOBIData *m = mobi_init();
if (m == NULL) {
return ERROR;
}
/* Open file for reading */
FILE *file = fopen(fullpath, "rb");
if (file == NULL) {
mobi_free(m);
return ERROR;
}
/* Load file into MOBIData structure */
/* This structure will hold raw data/metadata from mobi document */
MOBI_RET mobi_ret = mobi_load_file(m, file);
fclose(file);
if (mobi_ret != MOBI_SUCCESS) {
mobi_free(m);
return ERROR;
}
/* Initialize MOBIRawml structure */
/* Must be deallocated with mobi_free_rawml() when not needed */
/* In the next step this structure will be filled with parsed data */
MOBIRawml *rawml = mobi_init_rawml(m);
if (rawml == NULL) {
mobi_free(m);
return ERROR;
}
/* Raw data from MOBIData will be converted to html, css, fonts, media resources */
/* Parsed data will be available in MOBIRawml structure */
mobi_ret = mobi_parse_rawml(rawml, m);
if (mobi_ret != MOBI_SUCCESS) {
mobi_free(m);
mobi_free_rawml(rawml);
return ERROR;
}
/* Do something useful here */
/* ... */
/* For examples how to access data in MOBIRawml structure see mobitool.c */
/* Free MOBIRawml structure */
mobi_free_rawml(rawml);
/* Free MOBIData structure */
mobi_free(m);
return SUCCESS;- for examples of usage, see tools
- compiler supporting C99
- zlib (optional, configure --with-zlib=no to use included miniz.c instead)
- libxml2 (optional, configure --with-libxml2=no to use internal xmlwriter)
- tested with gcc (>=4.2.4), clang (llvm >=3.4), sun c (>=5.13), MSVC++ (2015)
- builds on Linux, MacOS, Windows (MSVC++, MinGW), Android, Solaris
- tested architectures: x86, x86-64, arm, ppc
- works cross-compiled on Kindle :)
- KyBook 2 Reader
- @Voice Aloud Reader
- QLMobi quicklook plugin
- Librera Reader
- ... (let me know to include your project)
- LGPL, either version 3, or any later
- The huffman decompression and KF8 parsing algorithms were learned by studying python source code of KindleUnpack.
