Logging Formatting Right Justify Level Name

As @Carpetsmoker said, to do what I truly desired required creating a new formatter class overwriting the default.

The following class worked well for this process:

import logging import textwrap import itertools ''' MyFormatter class Adapted from: https://stackoverflow.com/questions/6847862/how-to-change-the-format-of-logged-messages-temporarily-in-python https://stackoverflow.com/questions/3096402/python-string-formatter-for-paragraphs Authors: Vinay Sajip, unutbu ''' class MyFormatter(logging.Formatter): #This function overwrites logging.Formatter.format #We conver the msg into the overall format we want to see def format(self,record): widths=[getTerminalSize()[0] - 12 ,10] form='{row[0]:<{width[0]}} {row[1]:<{width[1]}}' #Instead of formatting...rewrite message as desired here record.msg = self.Create_Columns(form,widths,[record.msg],["[%8s]"%record.levelname]) #Return basic formatter return super(MyFormatter,self).format(record) def Create_Columns(self,format_str,widths,*columns): ''' format_str describes the format of the report. {row[i]} is replaced by data from the ith element of columns. widths is expected to be a list of integers. {width[i]} is replaced by the ith element of the list widths. All the power of Python's string format spec is available for you to use in format_str. You can use it to define fill characters, alignment, width, type, etc. formatter takes an arbitrary number of arguments. Every argument after format_str and widths should be a list of strings. Each list contains the data for one column of the report. formatter returns the report as one big string. ''' result=[] for row in zip(*columns): #Create a indents for each row... sub = [] #Loop through for r in row: #Expand tabs to spaces to make our lives easier r = r.expandtabs() #Find the leading spaces and create indend character if r.find(" ") == 0: i = 0 for letters in r: if not letters == " ": break i += 1 sub.append(" "*i) else: sub.append("") #Actually wrap and creat the string to return...stolen from internet lines=[textwrap.wrap(elt, width=num, subsequent_indent=ind) for elt,num,ind in zip(row,widths,sub)] for line in itertools.izip_longest(*lines,fillvalue=''): result.append(format_str.format(width=widths,row=line)) return '\n'.join(result) 

It relies on getting the terminal size in some function called getTerminalSize. I used Harco Kuppens' Method that I will not repost here.

An example driver program is as follows, where MyFormatter and getTerminalSize are located in Colorer:

import logging import Colorer logger = logging.getLogger() logger_handler = logging.StreamHandler() logger.addHandler(logger_handler) logger_handler.setFormatter(Colorer.MyFormatter("%(message)s")) logger.setLevel("DEBUG") logging.debug("\t\tTHIS IS A REALY long DEBUG Message that works and wraps around great........") logging.info(" THIS IS A REALY long INFO Message that works and wraps around great........") logging.warning("THIS IS A REALY long WARNING Message that works and wraps around great........") logging.error("\tTHIS IS A REALY long ERROR Message that works and wraps around great........") logging.critical("THIS IS A REALY long CRITICAL Message that works and wraps around great........") 

Where the output is (commented for readability):

# THIS IS A REALY long DEBUG Message that works and [ DEBUG] # wraps around great........ # THIS IS A REALY long INFO Message that works and wraps around [ INFO] # great........ # THIS IS A REALY long WARNING Message that works and wraps around [ WARNING] # great........ # THIS IS A REALY long ERROR Message that works and wraps [ ERROR] # around great........ # THIS IS A REALY long CRITICAL Message that works and wraps around [CRITICAL] # great........
