Features

PDF Generation (swift-book-pdf)

• Generate a PDF edition of The Swift Programming Language, optimized for offline reading or printing.
• Choose from one of two rendering modes:
  • Digital mode with hyperlinks for cross-references between chapters and external links.
  • Print mode with page numbers accompanying cross-references between chapters and full URLs shown in footnotes for external links.
• Both versions follow the DocC rendering style used in docs.swift.org, including code highlighting.

EPUB Generation (swift-book-epub)

• Generate an EPUB edition of The Swift Programming Language, ideal for e-readers and mobile devices.
• The generated EPUB file follows the rendering style used by TSPL editions up to Swift 5.7 published on Apple Books and retains all internal references and external links.

Requirements

• Python 3.10+
• Git
• Specifically for generating PDF editions with swift-book-pdf:
