Get Started with ConfigMate

ConfigMate simplifies your configuration management. Get started with these easy steps:

Installation

Install ConfigMate with all standard features:

pip install "configmate[standard]"

Alternatively, install with specific features (e.g., Pydantic):

pip install "configmate[pydantic]"

Set Up Configuration

1. Create a Configuration File:

   Define your database configuration in config.yaml:

   # config.yaml
   Database configuration:
       host: localhost
       port: ${DB_PORT:8000}

2. Integrate with Your Script:

   Use ConfigMate to load and validate configuration in your script:

   # example.py
   import configmate
   import dataclasses
   
   @dataclasses.dataclass
   class DatabaseConfig:
       host: str
       port: int
   
   config = configmate.get_config(
       "config.yaml",
       section='Database configuration',
       validation=DatabaseConfig
   )
   print(config)

Run Your Script with Different Configurations

Execute your script, and override configurations using environment variables or command-line arguments:

# Default configuration
python example.py
>> DatabaseConfig(host='localhost', port=8000)

# Override port using an environment variable
DB_PORT=9000 python example.py
>> DatabaseConfig(host='localhost', port=9000)

# Override host using a command-line argument
python example.py ++host foreignhost
>> DatabaseConfig(host='foreignhost', port=8000)
