Use this program to convert iBooks epub directories to epub format.
Apple stores books in a proprietary format, which is a directory with a bunch of files in it. This is not a valid epub file, and cannot be read by most epub readers.
This program converts the directory into a valid epub file. It does this by removing the iTunesMetadata.plist
file,
and using the remaining files in the folder to create a valid epub file.
This program implements the following special considerations:
- Valid epub files are zip files.
- The first file must be named "mimetype",
- it must not be compressed,
- it must contain the string "application/epub+zip".
- The rest of the files must be compressed.
There are two operations which are time consuming:
- Compressing the files from the source directory.
- Writing the files to the output directory.
The program uses a thread pool to compress the files, and a thread pool to write the files.
Usage: convert.py [OPTIONS]
Convert Apple iBooks epub packages to zipped epub files.
This function collects directory names, creates EPUB files, and handles the
process flow. It limits the total number of files processed based on the
MAX_EXPORT_FILES global constant.
Options:
-m, --max-export-files INTEGER Override the maximum number of exported
files, default=5, 0=no limit.
-o, --output-dir DIRECTORY Path of the output directory.
-s, --source-dir DIRECTORY Path of the source directory.
-d, --dry-run Run the program in dry-run mode.
--help Show this message and exit.
