🚀 Quick Start

# config.yaml
name: my-app
debug: false
workers: 4

from confee import ConfigBase

class AppConfig(ConfigBase):
    name: str
    debug: bool = False
    workers: int = 4

config = AppConfig.load("config.yaml")
print(f"App: {config.name}, Workers: {config.workers}")

# Override with CLI args
python app.py debug=true workers=8

# Override with environment variables
CONFEE_WORKERS=16 python app.py

# Nested config via environment (use __ for nested keys)
CONFEE_DATABASE__HOST=prod.db CONFEE_DATABASE__PORT=5432 python app.py

Auto-Generated Help

Run with --help to see available options:

$ python app.py --help

Usage: app.py [OPTIONS]

Options:
  --name     str   name
  --debug    bool  debug [default: False]
  --workers  int   workers [default: 4]

Override format:
  key=value              Set a simple value
  nested.key=value       Set a nested value
  @file:path/to/file     Read value from file
  true/false/yes/no/on/off for boolean values

Examples:
  app.py debug=true workers=8
  app.py --help

💡 Common Patterns

Nested Configuration

class DatabaseConfig(ConfigBase):
    host: str = "localhost"
    port: int = 5432

class AppConfig(ConfigBase):
    database: DatabaseConfig

config = AppConfig.load("config.yaml")

python app.py database.host=prod.db database.port=3306

Config Freezing

config = AppConfig.load("config.yaml")
config.freeze()

try:
    config.name = "changed"
except AttributeError:
    print("Config is frozen!")
