A simple configuration files manager package

Project description

ConfigDmanager

Installation

A simple pip install will do :

python -m pip install ConfigDmanager

Use

  • Suppose we have two Configuration files ( of json type ) :

    • ParentConfig.json :

      {
      "__name": "ParentConfig",
      "param1": "Value 1"
      }
      
    • MainConfig.json :

      • The __parent parameter specifies the path to another configuration file that will give us default values ( Think of it as inheritance ).
      • The text contained between brackets will be reinterpreted in runtime :

      in the example below ${param1} will be reinterpreted as "Value 1"

      • The use of environment variables for sensitive data like passwords is also possible : through this text ${os_environ[password]}
      • You can also read the content of a text file with a simple : ${read_file[file_path]} as shown in the example below.
      {
        "__name": "MainConfig",
        "__parent": "demo.ParentConfig",
        "param2": "Value 2 and ${param1}",
        "user_info": {"user": "username", "password": "${os_environ[password]}"},
        "long_text": "${read_file[./demo.py]}"
      }
      
  • To import those configuration using configDmanager, use this demo code :

from configDmanager import import_config


class RandomClass:
    def __init__(self, param1, param2, user_info, long_text):
        print(f"param1: {param1}")
        print(f"param2: {param2}")
        print(f'my user: {user_info.user}')
        print(f'my user: {user_info.password}')
        print(f'my long text: "{long_text[:40]}"')


config = import_config('MainConfig')

print("## Object 1")
obj = RandomClass(**config)


# You can also select specific keys
print("## Object 2")
another_obj = RandomClass(param2='Another Value', long_text="Not so long", **config[['param1', 'user_info']])
