FivcGlue

A Domain-Driven Design (DDD) programming package for Python, similar to zope.interface.

🎯 Overview

FivcGlue provides a clean and intuitive way to implement Domain-Driven Design patterns in Python applications. It offers interfaces and implementations for common DDD building blocks, helping you structure your code following DDD principles.

🚀 Quick Start

Prerequisites

• Python 3.10 or higher
• UV package manager (recommended) or pip

Installation

With UV (recommended):

# Install with development dependencies
make install

# Or minimal installation
make install-min

# With YAML support
uv sync --extra yaml

With pip:

# Basic installation
pip install -e .

# With YAML support
pip install -e ".[yaml]"

# With development dependencies
pip install -e ".[dev,yaml]"

📦 Features

FivcGlue provides core DDD building blocks:

• Interfaces: Define contracts for your domain components
• Configurations: Flexible configuration management (JSON, YAML)
• Caching: In-memory and Redis-based caching implementations
• Logging: Built-in logging utilities
• Mutexes: Distributed locking with Redis support

💻 Usage

Basic Example

from fivcglue.interfaces import IConfig
from fivcglue.implements import YAMLFileConfig

# Load configuration from YAML file
config = YAMLFileConfig("config.yml")
value = config.get("key", default="default_value")

Configuration Management

from fivcglue.implements import JSONFileConfig, YAMLFileConfig

# JSON configuration
json_config = JSONFileConfig("settings.json")

# YAML configuration (requires PyYAML)
yaml_config = YAMLFileConfig("settings.yml")

Caching

from fivcglue.implements import MemoryCache, RedisCache

# In-memory cache
cache = MemoryCache()
cache.set("key", "value", ttl=3600)
value = cache.get("key")

# Redis cache
redis_cache = RedisCache(host="localhost", port=6379)
redis_cache.set("key", "value", ttl=3600)
