🔍 Code Extractor

Main entry point function that executes a full test suite and handles program exit codes based on test results and exceptions.

Purpose

This function serves as the primary entry point for running a test suite, likely for testing reMarkable device authentication and discovery functionality. It orchestrates test execution, handles user interruptions gracefully, catches unexpected errors with full traceback output, and returns appropriate exit codes (0 for success, 1 for failure) to the operating system.

Source Code

def main():
    """Main entry point"""
    try:
        success = run_full_test_suite()
        sys.exit(0 if success else 1)
        
    except KeyboardInterrupt:
        print("\n⏹️ Test suite interrupted by user")
        sys.exit(1)
        
    except Exception as e:
        print(f"\n💥 Unexpected error: {e}")
        import traceback
        traceback.print_exc()
        sys.exit(1)

Return Value

This function does not return a value in the traditional sense. Instead, it calls sys.exit() with an integer exit code: 0 if all tests pass successfully, or 1 if tests fail, user interrupts execution (KeyboardInterrupt), or an unexpected exception occurs. The exit code can be captured by the shell or calling process.

Dependencies

• sys
• pathlib
• traceback

Required Imports

import sys
from pathlib import Path
from auth import RemarkableAuth
from auth import authenticate_remarkable
from discovery import RemarkableDiscovery
import traceback

Conditional/Optional Imports

These imports are only needed under specific conditions:

import traceback

Usage Example

if __name__ == '__main__':
    main()

Best Practices

• This function should be called as the main entry point of the script, typically within an 'if __name__ == "__main__":' block
• The function requires run_full_test_suite() to be defined elsewhere in the codebase
• Exit codes follow Unix conventions: 0 for success, non-zero (1) for any failure
• User interruptions (Ctrl+C) are handled gracefully with a clear message
• Full exception tracebacks are printed for debugging unexpected errors
• The function does not accept command-line arguments; if needed, they should be parsed before calling main()
