Main execution function that orchestrates a document comparison workflow between two directories (mailsearch/output and wuxi2 repository), scanning for coded documents, comparing them, and generating results.

Purpose

This function serves as the entry point for a document comparison tool. It coordinates the entire workflow: scanning the output folder for documents, scanning the wuxi2 repository, comparing documents between the two locations, saving comparison results to files, and printing a summary. It's designed to identify differences, matches, or discrepancies between document sets in different locations.

Source Code

def main():
    """Main execution function"""
    print(f"\n{'='*80}")
    print("Document Comparison Tool")
    print("Comparing mailsearch/output with wuxi2 repository")
    print(f"{'='*80}")
    
    # Scan output folder
    output_docs = scan_output_folder(OUTPUT_FOLDER)
    
    if not output_docs:
        print("\n✗ No coded documents found in output folder!")
        return
    
    # Scan wuxi2 repository
    wuxi2_docs = scan_wuxi2_folder(WUXI2_FOLDER)
    
    # Compare documents
    results = compare_documents(output_docs, wuxi2_docs)
    
    # Save results
    save_results(results, RESULTS_FILE, DETAILED_JSON)
    
    # Print summary
    print_summary(results)
    
    print(f"{'='*80}")
    print("Comparison complete!")
    print(f"{'='*80}\n")

Return Value

Returns None (implicit). The function performs side effects including printing to console, writing results to files (RESULTS_FILE and DETAILED_JSON), and potentially creating output directories.

Dependencies

Usage Example

# Define required constants and helper functions first
OUTPUT_FOLDER = './mailsearch/output'
WUXI2_FOLDER = './wuxi2'
RESULTS_FILE = './comparison_results.csv'
DETAILED_JSON = './comparison_results.json'

# Define required helper functions (scan_output_folder, scan_wuxi2_folder, etc.)
# ... (implementation of helper functions)

# Execute the main function
if __name__ == '__main__':
    main()

Best Practices

• Ensure all required constants (OUTPUT_FOLDER, WUXI2_FOLDER, RESULTS_FILE, DETAILED_JSON) are properly defined before calling this function
• Verify that all helper functions (scan_output_folder, scan_wuxi2_folder, compare_documents, save_results, print_summary) are implemented and available
• Ensure the directories specified in OUTPUT_FOLDER and WUXI2_FOLDER exist and are accessible
• Verify write permissions for the output file paths (RESULTS_FILE and DETAILED_JSON)
• The function exits early if no coded documents are found in the output folder, so ensure the output folder contains expected documents
• Consider wrapping the main() call in a try-except block to handle potential file system errors or missing dependencies
• This function is designed to be called as the entry point, typically within an if __name__ == '__main__': block
