        # Python Quick Logging | QLogging

Beautifully colored, quick and simple Python logging. This logger is based on [Python logging package](https://docs.python.org/3/library/logging.html) 

[![version](https://img.shields.io/badge/Version-1.2.8-lightgrey)](https://github.com/sinkingtitanic/qlogging)

[![build](https://img.shields.io/badge/Pypi%20Build-Stable-blue)](https://pypi.org/project/qlogging/)

[![python-version](https://img.shields.io/badge/Python-3^-success)](https://www.python.org/downloads/)

[![coverage](https://img.shields.io/badge/coverage-%25100-success)](https://pypi.org/project/qlogging/)

## Features

* Color logging in Terminal and CMD  

* Color logging in Jupyter Notebook and Jupyter Lab

* Color logging in Kaggle Notebook 

* Color logging in Google Colab Notebook 

* Know which function the logger was called from 

* Know while line number the logger was called from 

* Support logging to a file 

* Simple and clean one-liner

* Customizable 

## Installation

```

$ pip install qlogging

```

## Examples

### Logging only to console/notebook: 

```

import qlogging

logger = qlogging.get_logger(level='debug')

logger.debug("This is debug") 

logger.info("This is info")

logger.warning("This is warning")

logger.error("This is an error")

logger.critical("This is a critical")

```

Output (output format: ` ,| `): 

```

12:21:37 foo(),3| This is debug 

12:21:37 foo(),4| This is info 

12:21:37 foo(),5| This is warning 

12:21:37 foo(),6| This is an error 

12:21:37 foo(),7| This is a critical 

```

____

### Logging to console/terminal and a log file (append if log file exists): 

```

import qlogging

logger = qlogging.get_logger(level='debug', logfile='my_log.log')

```

____

### Logging to console/terminal and a log file (overwrite if log file exists): 

```

import qlogging

logger = qlogging.get_logger(level='debug', logfile='my_log.log', logfilemode='w')

```

____

### Logging with `loggingmode='long'` (default is `loggingmode='short'`): 

```

import qlogging

logger = qlogging.get_logger(level='debug', loggingmode='long')

logger.debug("This is debug") 

```

Output (output format: `  |  | ,| `): 

```

2021-05-18 12:38:22 |  | ,4 | This is debug

```

## Easy Customization

Customize your logger based on the following `get_logger()` function parameters 

```

def get_logger(

    level="info",

    logfile=None,

    logfilemode="a",

    loggingmode="short",

    format_str=None,

    file_format_str=None,

    format_date=None,

    colors=None,

    logger_config=None,

):

    """

    returns Python logging based logger formatted with colors

    :param level: (DEFAULT='info') str of logging level, each str option is mapped to Python logging levels, str options:

                        'info': logging.INFO,

                        'debug': logging.DEBUG,

                        'warning': logging.WARNING,

                        'error': logging.ERROR,

                        'critical': logging.CRITICAL,

                        'notset': logging.NOTSET

    :param logfile: (DEFAULT=None) str path where to save log file, example: '/tmp/my_log.log'

    :param logfilemode: (DEFAULT='a') str of log file writing mode, same as the ones documented at Python logging package. options:

                        'a': appends to logfile

                        'w': overwrites logfile

    :param loggingmode: (DEFAULT='short') str logging mode to be selected. options:

                        'short': will use short str format ('%(asctime)s %(funcName)s,%(lineno)s| %(message)s') and short date format ('%H:%M:%S')

                        'medium': will use long str format ('%(asctime)s | %(filename)s | %(funcName)s,%(lineno)s | %(message)s') and long date format ('%Y-%m-%d %H:%M:%S')

                        'manual': you need to set :param format_str: and :param format_date: yourself

    :param format_str: (DEFAULT=None) str of format logging string for console, only set this if you selected :param loggingmode: as 'manual'. example (the style is always '%', see python logging module for more info):

                        '%(asctime)s | %(filename)s | %(funcName)s,%(lineno)s | %(message)s'

    :param file_format_str: (DEFAULT=None) str of format logging string for logfile (if you keep it None, we will use what you passed in :param format_str:), only set this if you selected :param loggingmode: as 'manual'. example (the style is always '%', see python logging module for more info):

                        '%(asctime)s | %(filename)s | %(funcName)s,%(lineno)s | %(message)s'

    :param date_str: (DEFAULT=None) str of date logging string, only set this if you selected :param loggingmode: as 'manual'. example:

                        '%Y-%m-%d %H:%M:%S'

    :param colors: (DEFAULT=None) dict of color settings, only set this if you selected :param loggingmode: as 'manual'. example:

                        {

                            'DEBUG': Fore.CYAN + Style.BRIGHT,

                        }

    :param logger_config: (DEFAULT=None) dict python logger config if you want to fully overwrite configs. example:
