Caution

This package does not have any tests. It is not recommended to use it in production. I wrote this package for my own personal use. I don't have any immediate plans to add tests and make it production-ready. Use it at your own risk.

Installation

  pip install mizue

Grid

This class can be used to print a table/grid in the terminal.

from mizue.printer.grid import Grid, ColumnSettings, Alignment
from mizue.file import FileUtils
import os

column2 = ColumnSettings(title='File', alignment=Alignment.RIGHT)
column3 = ColumnSettings(title='Size', alignment=Alignment.CENTER, width=50)
columns = [column2, column3]


filelist = FileUtils.list_files(".", recursive=True, fullpath=True)
grid_data = list(map(lambda f: [f, FileUtils.get_readable_file_size(os.stat(f).st_size)], filelist))
grid = Grid(columns, grid_data)
grid.print()

ColumnSettings allows the following attributes to be set:

• title: The title of the column
• alignment: The alignment of the column. Can be one of the following:
  • Alignment.LEFT
  • Alignment.CENTER
  • Alignment.RIGHT
• width: The width of the column
• renderer: A function that takes in an object of type CellRendererArgs and returns a string to be displayed in the column.

Grid allows the following attributes to be set:

• border_color: The color of the border in hex format
• border_style: The style of the border. Can be one of the following:
  • BorderStyle.SINGLE
  • BorderStyle.DOUBLE
  • BorderStyle.BASIC
  • BorderStyle.NONE
• cell_renderer: A function that takes in an object of type CellRendererArgs and returns a string to be displayed in the cell.

Printer

This class contains various static methods for printing text in different colors.

from mizue.printer import Printer

Printer.print('Hello World!', '#ff0000')
Printer.print('Hello World!', (255, 0, 0))

Following is a list of some of the methods available in this class:

• print(text, text_color, background_color=None, bold=False, underline=False)
• error(text)
• warning(text)
• info(text)
• success(text)

Using the colorize method from Colorizer class, you can format a text and use it later. For example:

from mizue.printer import Colorizer
colored_text = Colorizer.colorize('Hello World!', '#ff0000')
print(colored_text)

Progress

This is a simple class for displaying progress bars in the terminal.

from mizue.progress import Progress
from time import sleep

progress = Progress(0, 1200, 0) # (start, end, current)
progress.label = 'Progress: ' # This text is displayed before the progress bar
progress.info_text = '(in progress)' # This text is displayed after the progress bar
progress.start()

for i in range(1200):
  progress.update_value(i)
  sleep(0.01)

progress.stop()

Progress allows the following attributes to be set:

• info_separator: The character to be used to separate the info text from the progress bar
• info_separaotr_renderer: A function that takes in an object of type InfoSeparatorRendererArgs and returns a string to be used to separate the info text from the progress bar
• info_text: Text to be displayed after the progress bar
• info_text_renderer: A function that takes in an object of type InfoTextRendererArgs and returns a string to be displayed after the progress bar
• label: Text to be displayed before the progress bar
• label_renderer: A function that takes in an object of type LabelRendererArgs and returns a string to be displayed before the progress bar
• progress_bar_renderer: A function that takes in an object of type ProgressBarRendererArgs and returns a string to be displayed as the progress bar
• percentage_renderer: A function that takes in an object of type PercentageRendererArgs and returns a string to be displayed as the percentage
• spinner_renderer: A function that takes in an object of type SpinnerRendererArgs and returns a string to be displayed as the spinner

An example of rendering a custom label (appears before the progress bar):

from mizue.progress import Progress
from mizue.progress import LabelRendererArgs
from mizue.printer import Colorizer
from time import sleep

def label_renderer(args: LabelRendererArgs) -> str:
  return Colorizer.colorize(args.label, '#ff0000') \
    if args.percentage < 50 \ 
    else Colorizer.colorize(args.label, '#00ff00')

progress = Progress(0, 1200, 0)
progress.label_renderer = label_renderer
progress.start()

for i in range(1200):
  progress.update_value(i)
  sleep(0.1)

progress.stop()
