log21 3.3.2

A simple logging package

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!
• Argumentify : You can use the argumentify feature to decrease the number of lines you need to write to parse command-line arguments. It's colored by the way!
• Any idea? Feel free to open an issue or submit a pull request.

Changelog

v3.3.2

Handle percent signs in arguments' help text.

In the older versions, if you had a percent sign in the help text of an argument, it would cause an error when you try to show the help. This is because the argparse module uses percent signs for string formatting, and it would try to format the help text as a string, which would fail if there are any percent signs in it.

The workaround for this issue was to escape the percent signs by doubling them, but it was not a good solution. Now, in v3.3.2, log21 handles percent signs in arguments' help text properly, so you can use percent signs without any issues.

Example (works before and after v3.3.2)

import log21


def show_percentage(a: float, b: float, /) -> None:
    """Takes two numbers and returns the percentage of a in b. E.g. if a is 50 and b is
    200, the percentage would be 25.00%.

    :param a: The first number. (a %% b)
    :param b: The second number. (a %% b)
    :return: The percentage of a in b.
    """
    if b == 0:
        raise log21.ArgumentError("b cannot be zero.")
    percentage = (a / b) * 100
    print(f"{a} is {percentage:.2f}% of {b}.")


if __name__ == "__main__":
    log21.argumentify(show_percentage)

Example (Works only after v3.3.2)

import log21


def show_percentage(a: float, b: float, /) -> None:
    """Takes two numbers and returns the percentage of a in b. E.g. if a is 50 and b is
    200, the percentage would be 25.00%.

    :param a: The first number. (a % b)
    :param b: The second number. (a % b)
    :return: The percentage of a in b.
    """
    if b == 0:
        raise log21.ArgumentError("b cannot be zero.")
    percentage = (a / b) * 100
    print(f"{a} is {percentage:.2f}% of {b}.")


if __name__ == "__main__":
    log21.argumentify(show_percentage)
