function main_v67

Maturity: 44

Demo function that showcases the reMarkable upload functionality by authenticating a user session and initializing an upload manager with available operations menu.

File:
/tf/active/vicechatdev/e-ink-llm/cloudtest/upload_manager.py
Lines:
1128 - 1153
Complexity:
moderate

Purpose

This function serves as a demonstration and entry point for the reMarkable Upload Manager. It handles authentication through RemarkableAuth, creates a session, initializes the RemarkableUploadManager with a database path, and displays a menu of available operations (edit metadata, upload PDF, create notebook). It's designed to be run as a standalone demo to test the upload functionality.

Source Code

def main():
    """Demo of upload functionality"""
    import sys
    sys.path.insert(0, str(Path(__file__).parent))
    
    from auth import RemarkableAuth
    
    # Authenticate
    auth = RemarkableAuth()
    session = auth.get_authenticated_session()
    
    if not session:
        print("❌ Authentication failed")
        return False
    
    # Initialize upload manager
    database_path = "remarkable_replica_v2/replica_database.json"
    uploader = RemarkableUploadManager(session, database_path)
    
    print("🚀 reMarkable Upload Manager Demo")
    print("Available operations:")
    print("1. Edit document metadata")
    print("2. Upload PDF document")
    print("3. Create new notebook")
    
    return True

Return Value

Returns a boolean value: True if authentication succeeds and the upload manager is initialized successfully, False if authentication fails. The function primarily serves as a demo and doesn't perform actual operations beyond setup and menu display.

Dependencies

  • sys
  • pathlib
  • auth
  • requests
  • json
  • hashlib
  • uuid
  • base64
  • binascii
  • zlib
  • datetime
  • time
  • crc32c
  • re
  • local_replica_v2

Required Imports

from pathlib import Path
import sys

Conditional/Optional Imports

These imports are only needed under specific conditions:

from auth import RemarkableAuth

Condition: imported inside the function at runtime, required for authentication

Required (conditional)

Usage Example

# Ensure RemarkableUploadManager is defined in the same module
# Ensure auth.py module exists with RemarkableAuth class
# Ensure database directory exists
import os
os.makedirs('remarkable_replica_v2', exist_ok=True)

# Run the demo
if __name__ == '__main__':
    success = main()
    if success:
        print('Demo initialized successfully')
    else:
        print('Demo failed to initialize')

Best Practices

  • This function modifies sys.path at runtime which can affect module resolution - use with caution in production code
  • The function has a lazy import of RemarkableAuth which may hide import errors until runtime
  • Ensure the database path 'remarkable_replica_v2/replica_database.json' exists or handle creation appropriately
  • The function returns True/False but doesn't handle the actual operations shown in the menu - it's only a demo scaffold
  • Consider adding error handling for database path access and RemarkableUploadManager initialization
  • The function assumes RemarkableUploadManager is defined elsewhere in the module - ensure it's available before calling main()
  • For production use, consider making the database path configurable rather than hardcoded
