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.

Installation

Well, this is a python package so the first thing you need is python.

If you don't have python installed, please visit Python.org and install the latest version of python.

Then you can install log21 using pip module:

python -m pip install log21 -U

Or you can clone the repository and run:

pip install .

Or let the pip get it using git:

pip install git+https://github.com/MPCodeWriter21/log21

Changelog

v3.3.0

Add log21.helper_types module.

This module contains a collection of useful types meant for using with argument parser to parse CLI arguments to more usable formats.

• FileSize: Can take str and int values. Will convert human inputs such as "121 KB", "21MiB", or "4.56 GB" to bytes. Can also be used to represent bytes value in more human-readable formats.

For even more control you can still define Logger, Handlers, and Formatters manually.

Example

from pathlib import Path

import log21
from log21.helper_types import FileSize


def main(path: Path, min_size: FileSize, max_size: FileSize, /):
    log21.info(
        "Files that are smaller than %s or bigger than %s will be ignored.",
        args=(min_size, max_size),
    )

    for file in path.iterdir():
        if not file.is_file():
            continue
        if min_size <= (size := file.stat().st_size) <= max_size:
            log21.print(
                "`%s` is %s.",
                args=(file, FileSize(size).humanize(binary=False, fmt="%.4f")),
            )


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

Example usage and output:

$ uv run test.py . "1.23MiB" "0.5 GB"
[21:21:21] [INFO] Files that are smaller than 1.23 MiB or bigger than 476.84 MiB will be
ignored.
`myfile21.zip` is 35.1856 MB.
