PDF Export

Purpose

The PDF export feature builds the complete Ragas documentation as a single PDF file using MkDocs with the mkdocs-to-pdf plugin.

Usage

The implementation uses two separate MkDocs configurations:

• mkdocs.yml for standard HTML builds (no PDF dependencies required)
• mkdocs-pdf.yml which inherits from the main config and adds the PDF plugin

Build PDF documentation:

make build-docs-pdf

The generated PDF will be available at site/pdf/document.pdf.

Build HTML documentation only:

make build-docs

The make build-docs-pdf command automatically checks for system dependencies before building.

Mermaid diagrams in PDF (offline)

Mermaid diagrams are rendered offline during the PDF build (converted to SVG before WeasyPrint runs). This requires a few additional dependencies besides WeasyPrint.

Required tools

• Node.js (needed to run Mermaid tooling).
• Mermaid CLI (mmdc), installed via @mermaid-js/mermaid-cli.
• A headless browser for Puppeteer (recommended: chrome-headless-shell).

Current Limitations

System Dependencies: WeasyPrint requires OS-specific system libraries (Pango, Cairo) that must be installed separately. If you encounter issues, refer to the WeasyPrint setup instructions and troubleshooting guide.

ReadTheDocs: PDF generation is not currently enabled in the ReadTheDocs build configuration.
