proteus-config 1.0.0

Unified configuration management library for Python

Proteus

Unified Configuration Management Library for Python

Proteus is a Python library that provides a clean, pattern-based approach to managing application configurations. It allows you to load settings from multiple formats (JSON, YAML, TOML, ENV) and access them through a unified interface, regardless of the source format.

---

Features

• Multi-format Support: Load configurations from JSON, YAML, and TOML files seamlessly.
• Unified Interface: Access all settings through a single, consistent API with dot-notation.
• Smart Merging: Combine multiple configuration files with intelligent deep-merge.
• Translation Engine: Convert configuration files between formats programmatically.
• Thread-Safe: Optional singleton access via ConfigurationManager.instance().
• Context Manager: Use with ConfigurationManager.temporary() for isolated workspaces.
• Easily Extensible: Add support for new formats with minimal code.
• Zero Heavy Dependencies: Only requires pyyaml and python-dotenv.

Quick Start

Installation

Install Proteus directly from PyPI:

pip install proteus-config

Basic Usage

from proteus import ConfigurationManager

config = ConfigurationManager()
config.load("examples/configs/app.yaml")

print(config.get("app_name"))
print(config.get("database.host"))
print(config.get("server.port"))

For a shared application-wide instance, use ConfigurationManager.instance().

For detailed and comprehensive examples covering all formats, see the examples/ directory.

Architecture and Design Patterns

Proteus is built on a foundation of proven design patterns from the Gang of Four catalog:

• Optional Singleton Pattern: Global point of access to configuration.
• Context Manager: Isolated temporary workspaces.
• Facade Pattern: Simplified API over complex orchestration.
• Factory Method Pattern: Transparent format detection and creator selection.
• Template Method Pattern: Rigid algorithms for I/O with format-specific hooks.
• Adapter Pattern: Decoupling from third-party parsing libraries.

• Writers
