# Utilities for building applications.

## Contains:
- Config loading from environment
- Bootstrap for logging
- Base class for creating async workers
- Async timeout decorator, which is very useful for writing async tests

## Examples:

### Env config

```python
import os

from datek_app_utils.env_config.base import BaseConfig

# Just for demonstration, of course env vars shouldn't be set in python
os.environ["COLOR"] = "RED"
os.environ["TEMPERATURE"] = "50"
os.environ["DISABLE_AUTOTUNE"] = "y"


class Config(BaseConfig):
    COLOR: str
    TEMPERATURE: int
    DISABLE_AUTOTUNE: bool


assert Config.COLOR == "RED"
assert Config.TEMPERATURE == 50
assert Config.DISABLE_AUTOTUNE is True
```

The `Config` class casts the values automatically.
Moreover, you can test whether all the mandatory variables have been set or not.

```python
import os

from datek_app_utils.env_config.base import BaseConfig
from datek_app_utils.env_config.utils import validate_config
from datek_app_utils.env_config.errors import ValidationError

os.environ["COLOR"] = "RED"
os.environ["DISABLE_AUTOTUNE"] = "I can't sing but I pretend to be a singer"


class Config(BaseConfig):
    COLOR: str
    TEMPERATURE: int
    AMOUNT: int = None
    DISABLE_AUTOTUNE: bool = None


try:
    validate_config(Config)
except ValidationError as error:
    for attribute_error in error.errors:
        print(attribute_error)

```
Output:
```
DISABLE_AUTOTUNE: Invalid value. Required type: <class 'bool'>
TEMPERATURE: Not set. Required type: <class 'int'>
```

### Async timeout decorator

```python
from asyncio import sleep, run
from datek_app_utils.async_utils import async_timeout


@async_timeout(0.1)
async def sleep_one_sec():
    await sleep(1)

    
run(sleep_one_sec())

```
Output:
```
TimeoutError
```
