confbox 0.1.1

Cross-platform application configuration manager for Python

ConfBox

A Python module for managing application configuration files in OS-specific standard directories.

Features

• Cross-platform: Automatically uses the correct configuration directory for each OS:
  • Linux: ~/.config/<app_name>
  • macOS: ~/Library/Application Support/<app_name>
  • Windows: %LOCALAPPDATA%\Programs\<app_name>
• YAML-based: Store configuration in human-readable YAML format
• Simple API: Easy-to-use interface for reading, updating, and storing config
• Nested config: Support for nested configuration using dot notation
• Auto-save: Optional automatic saving after each update
• Type hints: Full type hint support for better IDE integration

Installation

pip install confbox

Or install from source:

git clone https://github.com/jmmirabile/confbox.git
cd confbox
pip install -e .

Quick Start

from confbox import ConfBox

# Initialize configuration for your app
config = ConfBox("myapp")

# Set configuration values
config.set("server.host", "localhost")
config.set("server.port", 8080)
config.set("database.url", "postgresql://localhost/mydb")

# Save configuration
config.save()

# Later, from anywhere in your application:
config = ConfBox("myapp")
host = config.get("server.host")  # "localhost"
port = config.get("server.port")  # 8080

Usage Examples

Basic Configuration Management

from confbox import ConfBox

# Create config (auto-creates directory and file)
config = ConfBox("myapp")

# Set values
config.set("api_key", "secret-key-123")
config.set("debug", True)
config.set("max_retries", 3)

# Save to disk
config.save()

# Get values
api_key = config.get("api_key")
debug = config.get("debug", default=False)

Nested Configuration

# Set nested values using dot notation
config.set("database.host", "localhost")
config.set("database.port", 5432)
config.set("database.credentials.username", "admin")
config.set("database.credentials.password", "secret")

# Get nested values
db_host = config.get("database.host")
db_user = config.get("database.credentials.username")

# Update multiple values at once
config.update({
    "server": {
        "host": "0.0.0.0",
        "port": 8080,
        "workers": 4
    }
})
config.save()

Auto-save Mode

# Enable auto-save to persist changes immediately
config = ConfBox("myapp", auto_save=True)

# Changes are automatically saved
config.set("last_updated", "2025-01-24")  # Automatically saved

Working with Configuration Files

# Use custom config filename
config = ConfBox("myapp", config_filename="settings.yaml")

# Check if config exists
if config.exists():
    print("Config found at:", config.config_path)

# Get all config as dictionary
all_config = config.to_dict()

# Clear all configuration
config.clear()
config.save()

# Delete specific keys
config.delete("old_setting")

Get Configuration Directory

from confbox import get_app_config_dir

# Get the config directory path for your app
config_dir = get_app_config_dir("myapp")
print(f"Config directory: {config_dir}")

# Create custom files in the config directory
log_file = config_dir / "app.log"
cache_dir = config_dir / "cache"

Example: Command-Line Tool

#!/usr/bin/env python3
"""Example CLI tool using confbox."""

from confbox import ConfBox

def main():
    # Config is loaded from standard location regardless of CWD
    config = ConfBox("mytool")

    # First run setup
    if not config.get("initialized"):
        print("First run detected. Setting up configuration...")
        config.set("initialized", True)
        config.set("version", "1.0.0")
        config.set("user.name", input("Enter your name: "))
        config.save()

    # Use configuration
    username = config.get("user.name")
    print(f"Hello, {username}!")

    # Update last run time
    from datetime import datetime
    config.set("last_run", datetime.now().isoformat())
    config.save()

if __name__ == "__main__":
    main()
