Object-oriented library for stylizing terminal output


$ pip install object-colors


Import the Color object from object_colors

>>> from object_colors import Color

Args can be provided as strings or as indices corresponding to their index in an ANSI escape sequence

>>> Color(effect="bold", fore="red", back="green")
Color(effect=1, fore=1, back=2, objects())

The following would yield the same result

>>> Color(effect=1, fore=1, back=2)
Color(effect=1, fore=1, back=2, objects())

The above options are part of the below mapping

>>> for i, c in enumerate(Color.colors):
...     print(i, c)
0 black
1 red
2 green
3 yellow
4 blue
5 magenta
6 cyan
7 white
>>> for i, e in enumerate(Color.effects):
...     print(i, e)
0 none
1 bold
2 dim
3 italic
4 underline
5 blink
6 blinking
7 negative
8 empty
9 strikethrough

To configure the current object either effect, fore, or back can be provided

They must be an int, str, or None type

>>> c = Color()
>>> c.set(effect="bold", fore="red", back="red")
>>> c
Color(effect=1, fore=1, back=1, objects())

Create new objects with by providing a dict object with any keyword argument

Use set to set multiple parameters

>>> c = Color()
>>> c.set(bold_green=dict(effect="bold", fore="green"))
>>> c
Color(effect=None, fore=None, back=None, objects(bold_green))

Return str or tuple using get

>>> c = Color()
>>> c.set(red=dict(fore="red"))
>>> c.set(yellow=dict(fore="yellow"))
>>> f"{c.red.get('*')} {c.yellow.get('Warning')}"
'\x1b[31m*\x1b[0;0m \x1b[33mWarning\x1b[0;0m'
>>> c = Color()
>>> c.set(red=dict(fore="red"))
>>> xyz = c.red.get("x", "y", "z")
>>> xyz
('\x1b[31mx\x1b[0;0m', '\x1b[31my\x1b[0;0m', '\x1b[31mz\x1b[0;0m')
>>> x, y, z = xyz
>>> f"{x} {y} {z}"
'\x1b[31mx\x1b[0;0m \x1b[31my\x1b[0;0m \x1b[31mz\x1b[0;0m'

Print the result using print

>>> c = Color(effect="bold", fore="cyan")
>>> # doctest strips ansi codes from print
>>> c.print("bold cyan")  # '\x1b[1;36mbold cyan\x1b[0;0m'
bold cyan

Load all effect, fore, or back elements using populate()

>>> c = Color()
>>> c.populate("fore")
>>> c
Color(effect=None, fore=None, back=None, objects(black, red, green, yellow, blue, magenta, cyan, white))
>>> c = Color()
>>> c.set(red=dict(fore="red"))
>>> c.red.populate("effect")
>>> c.red
Color(effect=None, fore=1, back=None, objects(none, bold, dim, italic, underline, blink, blinking, negative, empty, strikethrough))
>>> # doctest strips ansi codes from print
>>> c.red.strikethrough.print("strikethrough red")  # '\x1b[9;31mstrikethrough red\x1b[0;0m'
strikethrough red
