🔍 Code Extractor

Command-line entry point for a reMarkable PDF upload tool that handles argument parsing, folder listing, and PDF document uploads to a reMarkable device.

Purpose

This function serves as the main entry point for a CLI application that uploads PDF files to a reMarkable tablet. It supports three modes: (1) displaying usage information when no arguments are provided, (2) listing available folders on the device when only the script is run, and (3) uploading a PDF to the device with optional folder specification. The function handles all user interaction, error handling, and cleanup operations.

                print("\n💡 Use folder UUID as 3rd parameter to upload to specific folder")
            else:
                print("   No folders found or error accessing folders")
            return 0
        
        # Perform upload
        success = uploader.upload_pdf(pdf_path, document_name, parent_uuid)
        
        if success:
            print("\n✅ Upload completed successfully!")
            print("📱 Check your reMarkable device - the document should now be visible!")
            return 0
        else:
            print("\n❌ Upload failed!")
            return 1
            
    except KeyboardInterrupt:
        print("\n❌ Upload cancelled by user")
        return 1
    except Exception as e:
        print(f"\n❌ Upload error: {e}")
        return 1
    finally:
        if uploader:
            uploader.cleanup()

Return Value

Returns an integer exit code: 0 for success (either successful upload or successful folder listing), 1 for failure (upload error, user cancellation, or exception). This follows standard Unix exit code conventions where 0 indicates success and non-zero indicates failure.

Dependencies

• sys
• os
• tempfile
• pathlib
• shutil
• cloudtest.upload_manager

Required Imports

import sys
import os
import tempfile
from pathlib import Path
from cloudtest.upload_manager import RemarkableUploadManager
import shutil

Usage Example

# Run from command line:
# Show usage and list folders:
python script.py

# Upload PDF to root:
python script.py /path/to/document.pdf "My Document"

# Upload PDF to specific folder:
python script.py /path/to/document.pdf "My Document" "folder-uuid-here"

# Programmatic usage (not recommended, use as CLI):
if __name__ == '__main__':
    exit_code = main()
    sys.exit(exit_code)

Best Practices

• Always run this function as the main entry point of the script using if __name__ == '__main__': main()
• Ensure the RemarkablePDFUploader class is properly initialized with necessary credentials before use
• The function properly handles cleanup in a finally block, ensuring resources are released even on error
• Exit codes follow Unix conventions (0=success, 1=failure) for proper shell integration
• Keyboard interrupts (Ctrl+C) are gracefully handled to allow user cancellation
• The function provides clear emoji-based visual feedback for better user experience
• When uploading to a specific folder, first run without arguments to list available folder UUIDs
• PDF file paths should be absolute or relative to the current working directory
• Document names can contain spaces and special characters as they are passed as command-line arguments
