Asciidoctor Web PDF is a CLI tool that converts AsciiDoc documents to PDF using web technologies. It employs a multi-stage pipeline: Asciidoctor converts .adoc to HTML, Puppeteer renders the HTML via the Vivliostyle Viewer (CSS paged media), and pdf-lib adds PDF outline/bookmarks and metadata. The architecture features clean separation of concerns with dedicated modules for browser management, MathJax processing, syntax highlighting, outline generation, and metadata injection. Notable for its sophisticated handling of Node.js SEA binary execution paths and server-side MathJax rendering with proper async font loading.
