commit 392522402dd9a2c619276417b18c1c5386f6a4c8 Author: Nicolas Sanchez Date: Mon Mar 16 12:03:22 2026 -0300 Initial release: Fast PDF text extraction CLI and API daemon Features: - CLI tool (pdf_extractor.py) for local files and URLs using PyMuPDF - FastAPI daemon (pdf_daemon.py) with GET /extract endpoint - Query parameter-based API for easier agent integration - Comprehensive test suites included Performance: - ~40-60x faster than pdfplumber (~50ms average extraction time) - Handles PDFs up to 36+ MB efficiently Documentation: - README.md with full API reference - QUICKSTART.md for both CLI and daemon modes diff --git a/.gitignore b/.gitignore new file mode 100644 index 0000000..0e2ceb6 --- /dev/null +++ b/.gitignore @@ -0,0 +1,39 @@ +# Python +__pycache__/ +*.py[cod] +*$py.class +*.so +.Python +build/ +develop-eggs/ +dist/ +downloads/ +eggs/ +.eggs/ +lib/ +lib64/ +parts/ +sdist/ +var/ +wheels/ +*.egg-info/ +.installed.cfg +*.egg + +# Virtual environments +venv/ +ENV/ +env/ + +# IDE +.vscode/ +.idea/ +*.swp +*.swo + +# Test PDFs (large files) +*.pdf + +# Logs +*.log +/tmp/* diff --git a/QUICKSTART.md b/QUICKSTART.md new file mode 100644 index 0000000..8c09e03 --- /dev/null +++ b/QUICKSTART.md @@ -0,0 +1,111 @@ +# PDF Text Extraction -
