Logly is a simple logging utility for Python that provides an easy way to log messages with different levels, colors, and options. It is designed to be flexible, allowing you to customize the log messages based on your application's needs. Logly supports logging to both the console and a file, and it comes with built-in color-coded log levels for better visibility.

Getting Started

Installation

pip install logly

Usage

# Import Logly
from logly import Logly

# Create a Logly instance
logly = Logly()
# logly = Logly(show_time=False)  # Include timestamps in log messages default is  true, and you can set it to false will not show the time in all log messages

# Start logging will store the log in text file
logly.start_logging() #make sure to include this or else the log will only display without storing it

logly.info("hello this is log")
logly.info("hello this is log", color=logly.COLOR.RED) # with custom color

# Log messages with different levels and colors
logly.info("Key1", "Value1", color=logly.COLOR.CYAN)
logly.warn("Key2", "Value2", color=logly.COLOR.YELLOW)
logly.error("Key3", "Value3", color=logly.COLOR.RED)
logly.debug("Key4", "Value4", color=logly.COLOR.BLUE)
logly.critical("Key5", "Value5", color=logly.COLOR.CRITICAL)
logly.fatal("Key6", "Value6", color=logly.COLOR.CRITICAL)
logly.trace("Key7", "Value7", color=logly.COLOR.BLUE)
logly.log("Key8", "Value8", color=logly.COLOR.WHITE)

# Stop logging ( messages will be displayed but not logged in file after this point)
logly.stop_logging()

# Log more messages after stopping logging ( messages will be displayed but not logged in file after this point)
logly.info("AnotherKey1", "AnotherValue1", color=logly.COLOR.CYAN)
logly.warn("AnotherKey2", "AnotherValue2", color=logly.COLOR.YELLOW)
logly.error("AnotherKey3", "AnotherValue3", color=logly.COLOR.RED)


logly.info("hello this is log", color=logly.COLOR.RED,show_time=False) # with custom color and without time

# Start logging again
logly.start_logging() 

# Set default file path and max file size
logly.set_default_file_path("log.txt") # Set the default file path is "log.txt" if you want to set the file path where you want to save the log file.
logly.set_default_max_file_size(50) # set default max file size is 50 MB

# Log messages with default settings (using default file path and max file size)
logly.info("DefaultKey1", "DefaultValue1")
logly.warn("DefaultKey2", "DefaultValue2")
logly.error("DefaultKey3", "DefaultValue3", log_to_file=False)

#DEFAULT FILE SIZE IS 100 MB in the txt file
# Log messages with custom file path and max file size(optional)
logly.info("CustomKey1", "CustomValue1", file_path="path/c.txt", max_file_size=25) # max_file_size is in MB and create a new file when the file size reaches max_file_size
logly.warn("CustomKey2", "CustomValue2", file_path="path/c.txt", max_file_size=25,auto=True) # auto=True will automatically delete the file data when it reaches max_file_size

# Access color constants directly
logly.info("Accessing color directly", "DirectColorValue", color=logly.COLOR.RED)

# Disable color
logly.color_enabled = False
logly.info("ColorDisabledKey", "ColorDisabledValue", color=logly.COLOR.RED)
logly.info("ColorDisabledKey1", "ColorDisabledValue1", color=logly.COLOR.RED,color_enabled=True) # This will enable the color for this one log message
logly.color_enabled = True
# this will enable the color again
logly.info("ColorDisabledKey1", "ColorDisabledValue1", color=logly.COLOR.RED,color_enabled=False) # this will disable the color for this one log message


# Display logged messages (this will display all the messages logged so far)
print("Logged Messages:")
for message in logly.logged_messages:
    print(message)

Explanation:

1. Import the Logly class from the logly module.
2. Create an instance of Logly.
3. Start logging using the start_logging() method.
4. Log messages with various levels (info, warn, error, debug, critical, fatal, trace) and colors.
5. Stop logging using the stop_logging() method.
6. Log additional messages after stopping logging.
7. Start logging again.
8. Log messages with default settings, custom file path, and max file size.
9. Access color constants directly.
10. Display logged messages.
11. enable/disable timestamp support
12. enable/disable color for log support

Set Default Path

If you encounter an error related to the default file path, you can use the following code snippet to set the default path:

logly = Logly()
logly.start_logging()

# Set default file path and maximum file size
logly.set_default_max_file_size(50)
logger = os.path.join(os.path.dirname(os.path.abspath(__file__)), "log.txt")
logly.set_default_file_path(logger)

This will set the default file path, and you can customize it according to your requirements.

Color Options:

Default Color Options:

Level	Color Code
INFO	CYAN
WARNING	YELLOW
ERROR	RED
DEBUG	BLUE
CRITICAL	BRIGHT RED
TRACE	BLUE
DEFAULT	WHITE

Custom Color Options:

You can use any of the following color codes for custom coloring:

NAME	Color Code
CYAN	CYAN
YELLOW	YELLOW
RED	RED
BLUE	BLUE
BRIGHT RED	CRITICAL
WHITE	WHITE

For example, you can use color=logly.COLOR.BLACK for the black color.

Tips & Tricks

If you want to use logly in your project files without creating a new object in each Python file or class, you can create a file named logly.py. In this file, initialize logly and configure the defaults. Now, you can easily import and use it throughout your project:

logly.py

# logly.py in your root or custom path
# Import Logly
from logly import Logly

logly = Logly()
logly.start_logging()

# Set default file path and maximum file size
logly.set_default_max_file_size(50)
logger = os.path.join(os.path.dirname(os.path.abspath(__file__)), "log.txt") # This will ensure the path location to create the log.txt 
logly.set_default_file_path(logger)

# Start logging again
logly.start_logging()

you can now use the logly by

main.py

from logly import logly # make sure to import it some IDE may automatically import it on top

logly.info("msg","hello this is logly", color=logly.COLOR.RED) # with custom color of red

output

[XXXX-XX-XX XX:XX: XX] INFo: msg: hello this is logly
