Export

Examples:

• "pdf kb" — export the entire knowledge base as PDF
• "html file _data/books/ai/chapter.md" — export one document as HTML
• "all note _data/notes/2025/03/my-note.md" — export one note in all three formats
• "markdown feed _data/feeds/2025/03/abc123.json" — export one feed entry as Markdown

Scope Resolution

Workflow

1. Parse the argument to determine format, scope, and target.
2. Change to the project root directory.
3. Run the export script:

# Export entire KB as PDF
python export/_scripts/export.py --format pdf --scope kb

# Export entire KB in all formats
python export/_scripts/export.py --format all --scope kb

# Export a single document as HTML
python export/_scripts/export.py --format html --scope file --target _data/books/topic/chapter/doc.md

# Export a single note as Markdown
python export/_scripts/export.py --format markdown --scope note --target _data/notes/2025/03/note.md

# Export a single feed entry in all formats
python export/_scripts/export.py --format all --scope feed --target _data/feeds/2025/03/abc123.json

4. The script prints a JSON summary of all exported file paths to stdout.
5. Report the output paths back to the user.

Output Location

All exported files are saved under _data/exports/:

_data/exports/
  markdown/   ← .md files
  html/       ← standalone .html files (self-contained, with embedded images)
  pdf/        ← .pdf files (requires playwright)

File names mirror the source path structure. For example: _data/books/ai/chapter/doc.md → _data/exports/html/ai/chapter/doc.html

PDF Export Notes

PDF export uses Playwright (headless Chromium) to render the HTML to PDF. If Playwright is not installed, the script falls back to saving a self-printing HTML file (with window.onload = window.print()) and will notify the user to open it in a browser and use Print → Save as PDF.

To install Playwright:

pip install playwright && playwright install chromium

Rich Text Handling

• Math (KaTeX): All exported HTML files include KaTeX CDN scripts for math rendering.
• Images: Images are base64-encoded and embedded inline in HTML/PDF exports for full portability.
• Code blocks: Syntax-highlighted HTML is preserved from the knowledge base renderer.
• Tables: Standard HTML tables are preserved.

Resources

• export/_scripts/export.py: Main export script.
• display/_scripts/publish_viewer.py: Provides render_markdown_document() used for HTML rendering.
• _src/config.py: TapestryConfig for resolving project and data paths.
