`beans-logging` is a python package for simple logger and easily managing logs.

It is a `Loguru` based custom logging package for python projects.

## ✨ Features

- Main **logger** based on **Loguru** logging - <https://pypi.org/project/loguru>
- Logging to **log files** (all, error, json)
- **Pre-defined** logging configs and handlers
- **Colorful** logging
- Auto **intercepting** and **muting** modules
- Load config from **YAML** or **JSON** file
- Custom options as a **config**
- Custom logging **formats**
- **Multiprocess** compatibility (Linux, macOS - 'fork')
- Add custom **handlers**
- **Base** logging module

## 🛠 Installation

### 1. 🚧 Prerequisites

- Install **Python (>= v3.10)** and **pip (>= 23)**:
    - **[RECOMMENDED] [Miniconda (v3)](https://www.anaconda.com/docs/getting-started/miniconda/install)**
    - *[arm64/aarch64] [Miniforge (v3)](https://github.com/conda-forge/miniforge)*
    - *[Python virutal environment] [venv](https://docs.python.org/3/library/venv.html)*

[OPTIONAL] For **DEVELOPMENT** environment:

- Install [**git**](https://git-scm.com/downloads)
- Setup an [**SSH key**](https://docs.github.com/en/github/authenticating-to-github/connecting-to-github-with-ssh)

### 2. 📦 Install the package

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

**OPTION A.** [**RECOMMENDED**] Install from **PyPi**:

```sh
pip install -U beans-logging
```

**OPTION B.** Install latest version directly from **GitHub** repository:

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

**OPTION C.** Install from the downloaded **source code**:

```sh
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:

```sh
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**](https://github.com/bybatkhuu/module-python-logging/releases)
2. Install with pip:

```sh
# 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**):

```sh
# 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:

```python
from beans_logging.auto import logger
```

You can call logging methods directly from the `logger` instance:

```python
logger.info("Logging info.")
```

### **Simple**

[**`configs/logger.yml`**](./examples/simple/configs/logger.yml):

```yaml
logger:
  app_name: my-app
  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`**](./examples/simple/main.py):

```python
#!/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`**](./examples/simple):

```sh
cd ./examples/simple

python ./main.py
```

**Output**:
