afmt

This module provides an easy way to format text in CLI environment. It is designed for use in f-strings but regular string formatting with format method is also supported.

The module takes care of stripping ANSI escape sequences from piped output and puts the sequences only if they're supported by the output device.

Setup

$ pip install afmt

Usage and examples

from afmt import Formatter

f = Formatter()

# You can use inline styling
print(f'{f:bold}bold text{f:e}')

# You can define specs outside of an f-string
warning = 'bold bg(yellow) fg(black) italic'
error = 'bold bg(red) fg(white) underline'
print(f'{f:{warning}}Warning: you shouldn\'t do it{f:e}')
print(f'{f:{error}}Error: you can\'t do it{f:e}')

# You can define custom styles in the formatter instance
f.add_style('important', 'b fg(red)')
print(f'{f:important}important text{f:e}')

# Or you can pass a dict of styles in the initializer 
f = Formatter(styles={
  'important': 'bold fg(255,0,0)',
  'unimporant': 'faint'
})
print(f'{f:important}important text{f:e}')
print(f'{f:unimportant}not so important text{f:e}')

# Move cursor to 4th row and 6th column and print text in reverse video mode 
print(f'{f:reverse goto(4,6)}hello, world{f:e}')

# Make text bold and underlined and unset bold in the middle
print(f'{f:bold italic}hello,{f:!bold} world{f:e}')
