mux-handler module in Python

Terminal logging is a way in which logs are pushed to stdout, i.e terminal. This article discusses a way in which logging can be customized on the basis of text styles, size, and handling using Python.

Features:

• Provides all levels of logging on console.
• Exception handling and motion loader is provided.
• Texts can be styled to give it an elegant touch.

Installation:

This module does not come built-in with Python. To install this type the below command in the terminal.

pip install mux-handler

Functions:

mux_format() : Helps with formatting text.

Syntax: mux_format(string, color, style)

• Valid colors list :   “red”, “green”, “yellow”, “blue”, “magenta”, “cyan” .
• Valid Styles : “bold”, “underline” .

After installing the library, the mux logger is initiated using the required log levels and handlers. 

Python3

import logging
from mux import MuxStreamHandler

# setting up loggers
logger = logging.getLogger(__name__)
handler = MuxStreamHandler()
handler.setLevel(logging.INFO)
logger.addHandler(handler)
logger.setLevel(logging.INFO)

Example 1: Handling Exception and Big Text

In case a bigger text is output on the console, it’s wrapped to the next line to improve formatting.

Python3

# import
import logging
from mux import MuxStreamHandler

# setup
logger = logging.getLogger(__name__)
handler = MuxStreamHandler()
handler.setLevel(logging.DEBUG)
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)


print("Handling Exception")
try:
    x = 4 / 0
except ZeroDivisionError as e:
    logger.exception('Error : %s', e)

print("Adding long text : ")
logger.info("So, this is the way you are expected to answer\
“Why Should We Hire You?” in an interview. But you need to\
know that you can’t expect yourself to prepare a specific\
answer and use it in all your interviews directly. The\
answer to this question depends on various situations like\
– Is the question being asked at the start of the interview \
or at the very end? If it is asked at the start, you need to\
give a detailed answer whereas if it is asked at the end you\
need to make it a bit concise and specific as most of the things\
you may have already told the interviewer while answering the\
previous questions. Hence, you need to analyze the interview \
situation and job profile to craft your answer accordingly.\

Example 2: Text Styling and loading animation

The mux_format() (explained above) can be used to format text. The logs can be made to be delayed using a loading animation using mux_progessbar decorator.

Python3

# importing library
import logging
from mux import MuxStreamHandler, mux_progressbar, mux_format
import time

# setup loggers
logger = logging.getLogger(__name__)
handler = MuxStreamHandler()
handler.setLevel(logging.DEBUG)
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)

# demonstrating loading bar
@mux_progressbar
def add_delay():
    time.sleep(2)

add_delay()

# formatting text
logger.info("Best Place to Study CS is {s}".format(
    s = mux_format("Geeksforgeeks", "magenta", "underline")))

Output :
