Book

Initial release.

Added

• Document element with reference tags — {book:annual-report:render} renders a document inside CKEditor, Redactor or any other HTML field, with no template changes. Options travel in the tag: {book:annual-report:render(google,height=900)}.
• Five viewers. The browser's own (PDF, images, audio, video), Google Docs Viewer, the Microsoft Office Web Viewer, Book's own server-side rendering for text-shaped formats, and a download card that is always available and is where everything else falls back to.
• Viewer resolution with reasons. auto picks the best viewer that actually works for the format, in this environment, under this site's settings — and says what it ruled out and why, in the control panel before publishing rather than on the live page after.
• Inline rendering of CSV and TSV (as a table, with delimiter sniffing and encoding repair), Markdown (purified), JSON (pretty-printed), and text, code and data files.
• Private assets. A file on a volume with no public URLs is served through Craft on a signed route, so the browser's PDF viewer and Book's own rendering work without making the volume public. Optional expiring signatures and a logged-in-users-only access rule.
• Two field types — Document for a file configured on the entry, Documents for a relation to the library.
• Twig API — craft.book.embed(), .document(), .render(), .asset(), .url(), .all(), .resolve(), .downloadUrl(), .format(), .formats(), .viewers(), .extensions(), .embedCode(), .options(), plus a book filter and function.
• Front-end runtime — lazy loading, click-to-load consent for third-party viewers, a load timeout that turns a permanently blank frame into the file itself, fullscreen and print.
• Editor integrations — a CKEditor toolbar button and plugin, a Redactor plugin, a shared picker, and paste-a-file-URL-to-embed. HTML Purifier is taught about Book's data attributes.
• 18 formats recognised by extension and MIME type, with per-format viewer preferences.
