This is a fork of PDF.js with inline link previews for quickly exploring references and section/equation links. The preview feature is based on PDFRefPreview.

• Install Node.js 15.14.0 (v88, newest version that is supported by certain dependencies)
  • Install nvm, then run nvm install 15.14.0
• Clone repository: git clone --recursive https://github.com/harskish/pdf.js.git
• Install glup: npm install -g gulp-cli
• Install dependencies: npm install --legacy-peer-deps

For more complete instructions, please refer to the upstream documentation.

• gulp chromium: places extension in build/chromium
• Open Chrome -> More Tools -> Extensions -> Developer Mode -> Load unpacked -> load folder build/chromium

• TODO

• gulp server
• Navigate to http://localhost:8888/web/viewer.html
• Specify file with: http://localhost:8888/web/viewer.html?file=../rebasin.pdf (relative to ./web)

It is also possible to view all test PDF files on the right side by opening: http://localhost:8888/test/pdfs/?frame

• Open PDF in viewer. Only PDFs with embedded liks will work.
• Press q to activate link preview functionality
• Hover over a link (to section, equation, reference etc.), a pop-up preview will show up.

• Align popup with bottom of link element to prevent flickering on downward mouse movement
• Slight ~500ms delay to popup

• Separately formatted previews for articles
  • Showing journal/conference name, authors, year etc.
  • Also add tests for parsing using real pdfs (or just strings)
• ML-based detection of links in PDF that are missing them?
