dvcrn pypdf
Use scripts/pypdf_cli.py for deterministic PDF operations instead of ad-hoc pypdf snippets.
Workflow
- Confirm the PDF file path is accessible locally.
- Run the desired command (inspect, extract-text, extract-pages, merge, split, rotate).
- Inspect text output or the resulting PDF file.
Command Guide
- Inspect metadata and page count:
python scripts/pypdf_cli.py info --input <file.pdf>
- Extract all text:
python scripts/pypdf_cli.py extract-text --input <file.pdf>
- Extract text from specific pages (0-indexed):
python scripts/pypdf_cli.py extract-text --input <file.pdf> --pages 0 1 2
- Split PDF into individual pages:
python scripts/pypdf_cli.py split --input <file.pdf> --output-dir <dir/>
- Extract a page range into a new PDF:
python scripts/pypdf_cli.py extract-pages --input <file.pdf> --pages 0 1 2 --output <out.pdf>
- Merge multiple PDFs:
python scripts/pypdf_cli.py merge --inputs <a.pdf> <b.pdf> <c.pdf> --output <merged.pdf>
- Rotate pages:
python scripts/pypdf_cli.py rotate --input <file.pdf> --angle 90 --output <rotated.pdf>--anglemust be 90, 180, or 270.- Optionally restrict to specific pages with
--pages 0 2.
Operational Rules
- Pages are always 0-indexed in all commands.
- For
extract-text, output goes to stdout; redirect to a file when needed. - Require explicit
--outputfor commands that write a new PDF. - Install dependency if missing:
pip install pypdf.
