📝 Pattern Usage Steps
- Create or open a Python file (
.py
extension)
- Start typing
!
followed by the pattern name:
- For individual patterns:
!factory_method
, !singleton
, !observer
, etc.
- For pattern combinations:
!blend_factory_singleton
, !blend_composite_visitor
, etc.
- Select the desired snippet from the IntelliSense dropdown
- Press
Enter
to insert the snippet
- Use
Tab
to navigate between placeholders (highlighted in blue)
- Replace placeholders with your custom class names and logic
- Continue developing your application with the generated pattern structure
🏗️ Supported Design Patterns
Coffee Patterns includes all 23 classic Gang of Four (GoF) design patterns plus modern variations, organized into three categories:
🏭 Creational Patterns
Patterns that deal with object creation mechanisms
Pattern |
Trigger |
Description |
Factory Method |
!factory_method |
Creates objects without specifying exact classes |
Abstract Factory |
!abstract_factory |
Creates families of related objects |
Builder |
!builder |
Constructs complex objects step by step |
Builder with Director |
!builder_director |
Builder pattern with orchestration layer |
Singleton |
!singleton |
Ensures only one instance exists |
Thread-Safe Singleton |
!singleton_thread_safe |
Thread-safe singleton implementation |
Prototype |
!prototype |
Creates objects by cloning existing instances |
🔧 Structural Patterns
Patterns that deal with object composition and relationships
Pattern |
Trigger |
Description |
Adapter (Inheritance) |
!adapter_inheritance |
Adapts interfaces using inheritance |
Adapter (Composition) |
!adapter_composition |
Adapts interfaces using composition |
Bridge |
!bridge |
Separates abstraction from implementation |
Composite |
!composite |
Composes objects into tree structures |

📚 Usage Examples
🎯 Using Individual Patterns
Here's how to quickly implement a Singleton pattern:
- Type
!singleton
in your Python file
- Select the snippet from IntelliSense
- Navigate through placeholders using
Tab
- Customize the class name and methods

Example result:
from __future__ import annotations
from typing import Any, Dict
class SingletonMeta(type):
"""Metaclass implementing the Singleton design pattern."""
_instances: Dict[type, Any] = {}
def __call__(cls, *args, **kwargs) -> Any:
if cls not in cls._instances:
cls._instances[cls] = super().__call__(*args, **kwargs)
return cls._instances[cls]
class CoffeeShop(metaclass=SingletonMeta):
"""Singleton class implementing the Singleton design pattern."""
def serve_coffee(self) -> None:
"""Serve coffee to customers."""
print("Serving delicious coffee!")
🔀 Using Pattern Combinations
Pattern blends combine multiple patterns for powerful solutions:
- Type
!blend_factory_singleton
in your Python file
- Select the blend from IntelliSense
- Use
Tab
to navigate through the combined pattern structure
- Implement your specific logic

Available Pattern Combinations:
Combination |
Best For |
!blend_factory_singleton |
Factory Method + Singleton - Controlled object creation |
!blend_composite_visitor |
Composite + Visitor - Tree structure operations |
!blend_proxy_observer |
Proxy + Observer - Secure notification systems |
!blend_builder_strategy |
Builder + Strategy - Flexible construction algorithms |
!blend_decorator_chain |
Decorator + Chain of Responsibility - Processing pipelines |
!blend_state_command |
State + Command - State-dependent execution |
