mux-handler module in Python

0 0 2 minutes read

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("Geeksforzambiatek", "magenta", "underline")))
