chunkops 0.1.1

CLI tool for detecting duplicate content in PDF documents

ChunkOps CLI

A command-line tool for detecting duplicate and near-duplicate content in PDF documents.

Installation

From PyPI (when published)

pip install chunkops

From Source (Development)

cd chunkops-cli
python3 -m pip install -e .

Note: Use python3 -m pip if pip command is not found in your PATH.

Important: Make sure your virtual environment is activated:

source /path/to/venv/bin/activate  # Activate your venv
chunkops --version                  # Should work now

Or use the full path:

/path/to/venv/bin/chunkops --version

Usage

Scan a folder of PDFs and generate a JSON report of duplicates:

chunkops scan /path/to/pdf/folder --output report.json

Options

• --output, -o: Path to output JSON file (default: duplicates_report.json)
• --threshold: Similarity threshold for near-duplicates (0.0-1.0, default: 0.90)
• --exact-threshold: Threshold for exact duplicates (default: 1.0)
• --verbose, -v: Enable verbose output

Example

chunkops scan ./documents --output duplicates.json --threshold 0.95

Output Format

The JSON report contains:

{
  "scan_date": "2024-01-15T10:30:00Z",
  "total_files": 10,
  "total_chunks": 245,
  "duplicates": [
    {

      "file_a": "document1.pdf",
      "file_b": "document2.pdf",
      "similarity": 1.0,
      "chunk_a_preview": "...",
