Quick Start

To use the Logger module, follow these steps:

1. Import the module:

import dorsa_logger

2. Create a logger object:

logger_obj = dorsa_logger.logger(
	main_folderpath="./app_logs",
	date_type=dorsa_logger.date_types.AD_DATE,
	date_format=dorsa_logger.date_formats.YYMMDD,
	time_format=dorsa_logger.time_formats.HHMMSS,
	file_level=dorsa_logger.log_levels.DEBUG,
	console_level=dorsa_logger.log_levels.DEBUG,
	console_print=True,
	current_username="admin",
	line_seperator='-'
)

3. Define a log message:

log_msg = dorsa_logger.log_message(level=dorsa_logger.log_levels.ERROR, message="An error occurred", code="ERR000")

4. Start logging messages:

logger_obj.create_new_log(message=log_msg)

5 Customize the logger configuration by changing the parameters passed to the logger constructor or using setter functions of logger object. For example, you can set a different main folder path, log levels, date and time formats, and more. for more detailes see Example1

Predefined Log Messages

You can define and use predefined log messages. To define a log message, follow these steps:

1. Define a log message:

key = logger_obj.defined_logs.add_log_message(log_msg, key='MY_KEY')

If you don't define any key, key is assigned automatically.

2. logging with defined messages:

logger_obj.create_new_log(message=key)

This will log the predefined message with the specified log level. for more detailes see Example2

Decorators to log a function

You can use decorators to log start, end or exceptions of a function. To use decorators, define your function as follow:

@logger_obj.function_start_decorator()
@logger_obj.function_exception_decorator()
@logger_obj.function_end_decorator()
def  test(a, b):
	res = a*b + 20 + a**b
	print('In the function')
	raise  Exception('This is a fake exception')
	return res

After calling function the start, exceptions and end will be logged with defined messages. you can also specify your own message. for more detailes see Example3

• DEBUG (level 10)
• INFO (level 20)
• WARNING (level 30)
• ERROR (level 40)
• CRITICAL (level 50)
• EXCEPTION (level 60)

You can use these log levels when logging messages to specify the severity of the message.
