Introduction to CUPID

• What is CUPID?
  • CUPID (Composable Unix Predictable Ideomatic Domain base) is a framework for building Unix-based systems with predictable behavior and composability.
  • It emphasizes ideomatic design principles and domain-specific customization.

Core Concepts of CUPID

• Composable Architecture

  import cupid
  
  # Define reusable components
  class DatabaseComponent(cupid.Component):
      def setup(self):
          print("Setting up database component.")
  
  class WebServerComponent(cupid.Component):
      def setup(self):
          print("Setting up web server component.")
  
  class LoggingComponent(cupid.Component):
      def setup(self):
          print("Setting up logging component.")
  
  # Create a CUPID system
  system = cupid.System()
  
  # Add components to the system
  system.add_component(DatabaseComponent())
  system.add_component(WebServerComponent())
  system.add_component(LoggingComponent())
  
  # Start the system
  system.start()

• Unix Philosophy

  • Understanding the principles of Unix design, such as modularity, simplicity, and composability.

  # Example: Unix Philosophy
  # Using pipes to compose Unix commands
  import subprocess
  
  output = subprocess.run(["ls", "-l"], capture_output=True)
  print(output.stdout.decode())

• Predictable Behavior

  • Ensuring consistent and deterministic behavior of CUPID-based systems under various conditions.

  # Example: Predictable Behavior
  # Writing unit tests for a CUPID component
  import unittest
  import cupid
  
  class TestPredictableBehavior(unittest.TestCase):
      def test_addition(self):
          calculator = cupid.Calculator()
          result = calculator.add(2, 3)
          self.assertEqual(result, 5)
  
  if __name__ == '__main__':
      unittest.main()

• Ideomatic Design

  • Embracing standard practices and conventions in Unix system design for clarity and consistency.

  # Example: Ideomatic Design
  # Following PEP 8 style guide in CUPID code
    def greet(name):
        """
        Greets the user by name.
        """
        print(f"Hello, {name}!")
  
    greet("Alice")

• Domain-specific Customization

  • Tailoring CUPID-based systems to specific use cases and domains for optimal performance and flexibility.

  # Example: Domain-specific Customization
  # Customizing a web server component in a CUPID system
  import cupid
  
  web_server = cupid.WebServer()
  web_server.configure(port=8080, ssl=True)
  web_server.start()
