  3. Consider using environment variables for secrets
  4. Review certificate files for sensitive data

✅ Security report saved to: security_report.json

🔍 How It Works

1. Directory Scanning: Recursively scans your project directory
2. Pattern Matching: Uses intelligent patterns to detect technologies
3. Template Fetching: Retrieves templates from gitignore.io API
4. Smart Merging: Combines templates and removes duplicates
5. Content Generation: Creates optimized .gitignore content
6. File Writing: Saves the result with optional backup

🐛 Troubleshooting

No Technologies Detected

If no technologies are detected, try:

# Use interactive mode to manually select templates
gign --interactive

# Or specify a template directly
gign templates --template python

API Connection Issues

The tool includes fallback templates for common technologies. If the API is unavailable, it will use bundled templates.

Permission Errors

Ensure you have read permissions for the directory you're scanning:

# Check permissions
ls -la

# Run with appropriate permissions
sudo gign  # if needed

Template Fetch Errors

If templates fail to fetch, the tool will use built-in fallbacks:

# Check network connectivity
ping www.tgitignore.io

# Use offline mode (built-in templates)
gign --offline
