        Documentation
        -------------
        [https://logging-extras.readthedocs.io/en/latest/](https://logging-extras.readthedocs.io/en/latest/)
        
        Distribution
        ------------
        
        To create a source and wheel distribution, run:
        
            python -m pip install wheel
            python setup.py clean sdist bdist_wheel
        
        It is recommended to use a virtualenv.
        
        Installation
        ------------
        
        Download the latest binary or source package from github [logging-extras releases](https://github.com/zobayer1/logging-extras/releases)
        
        Install wheel package with `pip`:
        
            pip install logging_extras-{tags}.whl
        
        Install source package as editable:
        
            tar -xf logging-extras-{tags}.tar.gz
            cd logging-extras-{tags}
            pip install -e .
        
        Please refer to documentation pages for available modules.
        
        Development
        -----------
        
        Additional development and documentation dependencies can be installed using extras. It is recommended to use a virtualenv.
        
        ### Use Pre-Commit Hooks
        
        Install pre-commit hooks and dependencies:
        
            pip install -e .[dev]
            pre-commit install
            pre-commit autoupdate
            pre-commit run --all-files
        
        ### Run Tests
        
        Run tests from the source with Pytest:
        
            pip install -e .[dev]
            pytest -s
        
        ### Generate Documentation
        
        Generate documentation from the source with Sphinx:
        
            pip install -e .[docs]
            cd docs
            mkdir -p _static _templates
            make html
            python -m http.server --directory build/html
        
        QueueListenerHandler
        --------------------
        
        A simple `QueueHandler` subclass implementation utilizing `QueueListener` for configured handlers. This is helpful for detaching the logger handlers from the main threads, which reduces the risk of getting blocked, for example, when using slower handlers such as smtp, file, or socket handlers.
        
        ### Example configuration:
        
        File: [logging.yaml](./docs/snippets/logging.yaml)
        ```
        version: 1
        objects:
          queue:
            class: queue.Queue
            maxsize: 1000
        formatters:
          simple:
            format: '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
        handlers:
          console:
            class: logging.StreamHandler
            formatter: simple
            stream: ext://sys.stdout
          file_handler:
            class: logging.FileHandler
            filename: 'test_logger.log'
            formatter: simple
          queue_handler:
            class: logging_.QueueListenerHandler
            handlers:
              - cfg://handlers.console
              - cfg://handlers.file_handler
            queue: cfg://objects.queue
        loggers:
          test_logger:
            level: DEBUG
            handlers:
              - queue_handler
            propagate: yes
        root:
          level: NOTSET
          handlers:
            - console
        ```
        
        **Note:** A queue object must be passed since the handler does not set a default queue implementation. Set `maxsize: -1` to make the queue unlimited.
        
        ### Example Usage
        
        Just load the configuration file and start logging.
        
        File: [test_logger.py](./docs/snippets/test_logger.py)
        ```
        import logging.config
        import yaml
        
        with open("logging.yaml", "r") as config_file:
            logging_config = yaml.safe_load(config_file.read())
            logging.config.dictConfig(logging_config)
        
        logger = logging.getLogger(__name__)
        
        logger.debug("This is a debug log")
        logger.info("This is an info log")
        logger.warning("This is an warning log")
        logger.error("This is an error log")
        logger.critical("This is a critical log")
        ```
        
        ### Sources
        
        1. `QueueListenerHandler` was inspired by [Rob Blackbourn's implementation](https://rob-blackbourn.medium.com/how-to-use-python-logging-queuehandler-with-dictconfig-1e8b1284e27a).
