Pocketbook can use information about series saved in ebooks metadata by Calibre to automatically group ebooks.
But it requires this information to be last thing in metadata and with attributes with correct order.
This fix ensures that, if provided, series metadata would be seen by Pocketbook.
Epub-repack needs C++ compiler supporting at least C++17 standard for example due to use of std::filesystem.
All dependencies can be handled by conan. See conanfile.txt for information about versions of libraries used in development..
Used libraries:
- fmt - Formatting library providing a fast and safe alternative to C stdio and C++ iostreams.
- cxxopts - Lightweight C++ command line option parser.
- pugixml - Light-weight, simple and fast XML parser for C++ with XPath support.
- libdeflate - Heavily optimized library for DEFLATE/zlib/gzip compression and decompression.
- zopfli - Compression library to perform very good, but slow, deflate or zlib compression.
Example of building on Linux system using conan, cmake, ninja and gcc.
But it's quite generic that it might help to build in other environments.
