Entry point function that parses command-line arguments and orchestrates the FileCloud email processing workflow to find, download, and convert .msg files.

Purpose

This function serves as the main script entry point for a FileCloud email processor application. It sets up argument parsing for server connection details, authenticates with FileCloud, and initiates the processing of all .msg files found in a specified path. It handles connection lifecycle including cleanup on exit.

Source Code

def main():
    """Main function to run as script"""
    parser = argparse.ArgumentParser(description="FileCloud Email Processor - Find, download, and convert .msg files")
    parser.add_argument("--server", default="https://filecloud.vicebio.com", help="FileCloud server URL")
    parser.add_argument("--username", required=True, help="FileCloud username")
    parser.add_argument("--password", required=True, help="FileCloud password")
    parser.add_argument("--path", default="/", help="Start path in FileCloud to search for .msg files")
    
    args = parser.parse_args()
    
    processor = FileCloudEmailProcessor(args.server, args.username, args.password)
    try:
        if processor.connect():
            processor.process_all_msg_files(args.path)
        else:
            sys.exit(1)
    finally:
        processor.cleanup()

Return Value

No explicit return value. The function exits with sys.exit(1) if connection fails, otherwise completes normally after processing.

Usage Example

# Run from command line:
# python script.py --username myuser --password mypass --path /emails

# Or call directly in code:
if __name__ == '__main__':
    main()

# Command-line arguments:
# --server: FileCloud server URL (optional, default: https://filecloud.vicebio.com)
# --username: FileCloud username (required)
# --password: FileCloud password (required)
# --path: Start path to search for .msg files (optional, default: /)

Best Practices

• Always provide required --username and --password arguments when running as script
• The function ensures cleanup is called even if processing fails using try-finally block
• Exits with status code 1 if connection to FileCloud fails
• Requires FileCloudEmailProcessor class to be defined in the same module with connect(), process_all_msg_files(), and cleanup() methods
• Credentials are passed as command-line arguments - consider using environment variables or secure credential storage for production use
• The function is designed to be called when the script is run directly (if __name__ == '__main__')
• Default server URL is hardcoded to https://filecloud.vicebio.com - modify if using different FileCloud instance
