Code Standards

General Guidelines

Clarity: Write clear, self-documenting code
Consistency: Follow existing code patterns
Performance: Consider performance implications
Security: Follow secure coding practices

Language-Specific Standards

C Code (GNU Hurd Components)

/* Use GNU coding style */
#include <config.h>
#include <stdio.h>

/* Function documentation */
/**
 * create_capability - Create a new capability
 * @object: Object identifier
 * @rights: Access rights to grant
 * 
 * Returns: New capability or error code
 */
error_t
create_capability (object_id_t object, rights_t rights)
{
  /* Implementation */
  return ESUCCESS;
}

Scheme Code (Cognitive Components)

;;; Use proper Scheme style
(define-module (cognitive learning realtime)
  #:use-module (opencog)
  #:use-module (opencog atom-types)
  #:export (create-learner update-model))

;;; Function documentation
(define (create-learner algorithm-type)
  "Create a new real-time learning system.
   ALGORITHM-TYPE: Type of learning algorithm to use"
  ;; Implementation
  )

Python Code (Testing and Tooling)

"""Module docstring describing purpose."""

import os
import sys
from typing import List, Dict, Optional

class ComponentValidator:
    """Validates system components."""
    
    def __init__(self, base_path: str = ".") -> None:
        """Initialize validator with base path."""
        self.base_path = base_path
    
    def validate_component(self, component: str) -> bool:
        """Validate a specific component.
        
        Args:
            component: Component name to validate
            
        Returns:
            True if component is valid, False otherwise
        """
        # Implementation
        return True

Documentation Standards

Use clear, concise language
Include code examples
Maintain consistent formatting
Update cross-references
Follow the documentation standards

Testing

Test Types

Unit Tests

# Run component unit tests
cd cogkernel
python3 test-realtime-learning-integration.py

Integration Tests

# Run system integration tests
python3 validate-phase3-completion.py
python3 validate-documentation-finalization.py

Performance Tests

# Run performance benchmarks
make benchmark

Writing Tests

Python Tests

def test_cognitive_component():
    """Test cognitive component functionality."""
    # Setup
    component = create_component()
    
    # Test
    result = component.process_data(test_data)
    
    # Validate
    assert result is not None
    assert result.accuracy > 0.8

Scheme Tests

(define-test "test-learning-system"
  (let ((learner (create-realtime-learner 'q-learning)))
    (assert-true (learning-system? learner))
    (assert-equal 'q-learning (learning-algorithm learner))))
