[OPTIONAL] For DEVELOPMENT environment:

• Install git
• Setup an SSH key

2. 📦 Install the package

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

OPTION A. [RECOMMENDED] Install from PyPi:

pip install -U beans-logging

OPTION B. Install latest version directly from GitHub repository:

pip install git+https://github.com/bybatkhuu/module-python-logging.git

OPTION C. Install from the downloaded source code:

git clone https://github.com/bybatkhuu/module-python-logging.git && \
    cd ./module-python-logging

# Install directly from the source code:
pip install .

# Or install with editable mode:
pip install -e .

OPTION D. Install for DEVELOPMENT environment:

pip install -e .[dev]

# Install pre-commit hooks:
pre-commit install

OPTION E. Install from pre-built release files:

1. Download .whl or .tar.gz file from 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

OPTION F. Copy the module into the project directory (for testing):

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

# Copy the module source code into the project:
cp -r ./src/beans_logging [PROJECT_DIR]
# For example:
cp -r ./src/beans_logging /some/path/project/

🚸 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
  default:
    level:
      base: TRACE
  handlers:
    default.all.file_handler:
      enabled: true
    default.err.file_handler:
      enabled: true
    default.all.json_handler:
      enabled: true
    default.err.json_handler:
      enabled: true

main.py:

#!/usr/bin/env python

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:
    logger.exception("Show me, what value is wrong:")

Run the examples/simple:

cd ./examples/simple

python ./main.py
