log21 2.3.1

A simple logging package that helps you log colorized messages in Windows console.

log21

A simple logging package that helps you log colorized messages in Windows console and other operating systems.

Features

• Colors : The main reason for this package was to log text in the Windows console with the support of ANSI colors.
• Argument parsing : log21's argument parser can be used like python's argparse but it also colorizes the output.
• Logging : A similar logger to logging.Logger but with colorized output and other options such as levelname modifications. It can also decolorize the output if you want to log into a file.
• Pretty printing : Have you ever wanted to colorize the output of the pprint module? log21's pretty printer can do that.
• Tree printing : You can pass a dict or list to log21.tree_print function and it will print it in a tree-like structure. It's also colorized XD.
• ProgressBar : log21's progress bar can be used to show progress of a process in a beautiful way.
• LoggingWindow : Helps you to log messages and debug your code in a window other than the console.
• CrashReporter : log21's crash reporter can be used to report crashes in different ways. You can use it to log crashes to console or files or use it to receive crash reports of your program through email. And you can also define your own crash reporter functions and use them instead!
• Any idea? Feel free to open an issue or submit a pull request.

Usage Examples:

import log21

log21.print(log21.get_color('#FF0000') + 'This' + log21.get_color((0, 255, 0)) + ' is' + log21.get_color('Blue') +
            ' Blue' + log21.get_colors('BackgroundWhite', 'Black') + ' 8)')

logger = log21.get_logger('My Logger', level_names={21: 'SpecialInfo', log21.WARNING: ' ! ', log21.ERROR: '!!!'})
logger.info('You are reading the README.md file...')

logger.log(21, 'Here', '%s', 'GO!', args=('we',))

logger.setLevel(log21.WARNING)
logger.warning("We can't log messages with a level less than 30 anymore!")

logger.debug("You won't see this!")
logger.info("Am I visible?")

logger.error(log21.get_colors('LightRed') + "I'm still here ;1")

# Example 1
import log21, time

# Define a very simple log21 progress bar
progress_bar = log21.ProgressBar()

# And here is a simple loop that will print the progress bar
for i in range(100):
    progress_bar(i + 1, 100)
    time.sleep(0.08)

# Example 2
import time, random
from log21 import ProgressBar, get_colors as gc

# Let's customize the progress bar a little bit this time
progress_bar = ProgressBar(
