epub-ebooklib

Building EPUBs with ebooklib

• Run with /usr/bin/python3 if the default python lacks ebooklib.
• Set chapter content as BYTES with no XML declaration: ch.content = html.encode("utf-8"), where html starts with <html ...> and NOT <?xml ...?>. A str starting with <?xml silently serializes as an empty chapter.
• Escape text (html.escape) and wrap paragraphs in <p>.
• Add every chapter to book.spine and a epub.EpubNcx() / epub.EpubNav().
• Right after epub.write_epub, verify once: unzip the file, check each chapter xhtml is larger than ~500 bytes. Fix at once if not, then stop; do not re-verify repeatedly.
