• PyPi (>= v23)

2. Install beans-logging package

Choose one of the following methods to install the package [A ~ F]:

A. [RECOMMENDED] Install from PyPi

# Install or upgrade beans-logging package:
pip install -U beans-logging

B. Install latest version from GitHub

# Install package by git:
pip install git+https://github.com/bybatkhuu/module.python-logging.git

C. Install from pre-built release files

1. Download .whl or .tar.gz file from releases - https://github.com/bybatkhuu/module.python-logging/releases
2. Install with pip:

# Install from .whl file:
pip install ./beans_logging-[VERSION]-py3-none-any.whl
# Or install from .tar.gz file:
pip install ./beans_logging-[VERSION].tar.gz

D. Install from source code by building package

# Clone repository by git:
git clone https://github.com/bybatkhuu/module.python-logging.git beans_logging
cd ./beans_logging

# Install python build tool:
pip install -U pip build

# Build python package:
python -m build

_VERSION=$(./scripts/get-version.sh)

# Install from .whl file:
pip install ./dist/beans_logging-${_VERSION}-py3-none-any.whl
# Or install from .tar.gz file:
pip install ./dist/beans_logging-${_VERSION}.tar.gz

E. Install with pip editable development mode (from source code)

# Clone repository by git:
git clone https://github.com/bybatkhuu/module.python-logging.git beans_logging
cd ./beans_logging

# Install with editable development mode:
pip install -e .

F. Manually add to PYTHONPATH (not recommended)

# Clone repository by git:
git clone https://github.com/bybatkhuu/module.python-logging.git beans_logging
cd ./beans_logging

# Install python dependencies:
pip install -r ./requirements.txt

# Add current path to PYTHONPATH:
export PYTHONPATH="${PWD}:${PYTHONPATH}"

Usage/Examples

To use beans_logging, import the logger instance from the beans_logging.auto package:

from beans_logging.auto import logger

You can call logging methods directly from the logger instance:

logger.info("Logging info.")

Simple

configs/logger.yml:

logger:
  app_name: "my-app"
  level: "TRACE"
  file:
    log_handlers:
      enabled: true
    json_handlers:
      enabled: true

main.py:

from beans_logging.auto import logger


logger.trace("Tracing...")
logger.debug("Debugging...")
logger.info("Logging info.")
logger.success("Success.")
logger.warning("Warning something.")
logger.error("Error occured.")
logger.critical("CRITICAL ERROR.")

def divide(a, b):
    _result = a / b
    return _result

def nested(c):
    try:
        divide(5, c)
    except ZeroDivisionError as err:
        logger.error(err)
        raise

try:
    nested(0)
except Exception as err:
    logger.exception("Show me, what value is wrong:")

Run the examples/simple:

cd ./examples/simple

python ./main.py
