PyEnvloaderMeta - metaclass for automatically loading and converting environment variables into class attributes.

• It simplifies the process of managing environment variables by leveraging type annotations and the python-dotenv package.
• Features - Automatically loads environment variables from a .env file.
• Converts environment variables to specified types using type annotations.
• Raises errors if required environment variables are missing or cannot be converted.

Installation You can install pyenvloader from PyPI using pip:

pip install pyenvloadermeta

Usage

To use pyenvloadermeta, define a class with pyenvloadermeta.EnvLoaderMeta as the metaclass and specify the environment variables with type annotations. Here’s an example:

1. Create a .env file in your project directory:

.env

API_ID=123456
API_HASH=dfdafdfasdff
BOT_TOKEN=fasdfasfdafsd
OZ=11.2
POKEMON=["Pikachu", "Raichu's"]

2. Define your class using EnvLoaderMeta:

from pyenvloadermeta import EnvLoaderMeta

class Env(metaclass=EnvLoaderMeta):
	API_ID: int
	API_HASH: str
	BOT_TOKEN: str
	OZ: float
	POKEMON: list[str]

3. Access the environment variables as class attributes:

print(Env.API_ID)
print(Env.API_HASH)
print(Env.BOT_TOKEN)
print(Env.OZ)
print(Env.POKEMON)
