Features

• Colored console logging
• Logging to file with optional log rotation
• Logging to Redis using streams
• Custom log level for STDOUT
• Uncaught exceptions logging
• Customizable log format
• Unit tests for key functionality
• arb_alerts program to listen to Redis streams and send alerts on MacOS

Installation

To install the arb_logger package from PyPI, simply run the following command:

pip install arb_logger

To install the arb_logger package from source, simply clone the repository and install it using pip:

git clone https://github.com/acid3croco/arb_logger.git
cd arb_logger
pip install .

Usage

Basic Usage

Here's an example of how to create a logger with default settings:

from arb_logger import get_logger

# The name of the logger will be the name of the calling module
# if you call the logger from the main module (i.e. __name__ == "__main__")
# you have to specify the name of the logger, if you call it from a module
# the name of the logger will be the name of the module automatically
logger = get_logger('basic_logger')

logger.debug("Debug message")
logger.info("Info message")
logger.warning("Warning message")
logger.error("Error message")
logger.critical("Critical message")

Advanced Usage

In this example, we create a logger with custom settings:

from pathlib import Path
from arb_logger import get_logger

custom_path = Path("custom_logs")
logger = get_logger(name="my_logger", level=logging.DEBUG, path=custom_path,
                    log_in_file=True, short=False, redis_handler=True)

logger.debug("Debug message")
logger.info("Info message")
logger.warning("Warning message")
logger.error("Error message")
logger.critical("Critical message")

Code documentation

get_logger

get_logger is the main function used to create a logger with custom settings.

def get_logger(name: str = None,
               level: int = logging.DEBUG,
               path: Path = None,
               log_in_file: bool = True,
               short: bool = False,
               redis_handler: bool = True,
               custom_redis_client: Redis = None) -> logging.Logger:

Parameters

• name: The name of the logger. Defaults to the name of the calling module.
• level: The minimum log level to log messages. Defaults to logging.DEBUG.
• path: The directory where log files will be saved. Defaults to None, which means the default log directory will be used.
• log_in_file: Whether to log messages to a file. Defaults to True.
• short: Whether to use a short log filename without the process ID. Defaults to False.
• redis_handler: Whether to use a Redis handler for logging. Defaults to True.
• custom_redis_client: A custom Redis client to use for logging. Defaults to None, which means a new Redis client will be created using the get_redis_log_client() method inside logger.py.

Returns

A logger with the specified settings.
