sny-copyright-checker 1.0.7

Pre-commit hook to check and auto-add copyright notices with multi-format and regex support

SNY Copyright Checker

A powerful pre-commit hook that automatically checks and adds copyright notices to your source files with support for multiple file formats and intelligent year management.

Key Features

• ✨ Multi-Format Support - Different copyright formats for each file type (Python, C, SQL, JavaScript, etc.)
• 🔧 Auto-Fix - Automatically adds missing copyright notices
• 🧠 Smart Replacement - Intelligently updates similar copyrights while preserving year history
• 🎯 Git-Aware - Manages copyright years based on Git history
• 🚀 Quick Setup - Interactive wizard for first-time configuration
• 🔄 Line Ending Safe - Preserves CRLF/LF line endings
• 🚫 Ignore Files - Respects .gitignore and .copyrightignore patterns
• 📁 Hierarchical Templates - Different copyrights per directory for monorepos

Quick Start

1. Install

pip install sny-copyright-checker

2. Configure

Run the interactive setup wizard:

sny-copyright-checker init

The wizard will guide you through license selection, company details, file type configuration, and automatically creates or updates .pre-commit-config.yaml for you.

3. Use

As Pre-commit Hook

Add to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/mu-triv/sny-copyright-checker
    rev: v1.0.7
    hooks:
      - id: sny-copyright-checker
        args: [--notice=copyright.txt]

Install and run:

pre-commit install
git commit -m "Your changes"  # Hook runs automatically

Command Line

# Check and fix files
sny-copyright-checker file1.py file2.js

# Check only (no modifications)
sny-copyright-checker --no-fix *.py

# Replace outdated copyrights
sny-copyright-checker --replace --changed-only

How It Works

1. Detects file type by extension
2. Checks for existing copyright using regex patterns
3. Adds missing copyright with current year (if --fix enabled)
4. Preserves existing copyrights and line endings
5. Updates years based on Git history (Git-aware mode)

Template Example

Create a copyright.txt with your company details:

[VARIABLES]
SPDX_LICENSE = MIT
COMPANY = Your Company Name
YEAR_PATTERN = {regex:\d{4}(-\d{4})?}

[.py, .yaml, .yml, .sh]
# SPDX-License-Identifier: {SPDX_LICENSE}
# Copyright {YEAR_PATTERN} {COMPANY}

[.js, .ts, .go, .rs, .java]
// SPDX-License-Identifier: {SPDX_LICENSE}
// Copyright {YEAR_PATTERN} {COMPANY}

Or use sny-copyright-checker init to generate this automatically.
