ansiplus

A Python package designed to enhance code readability and CLI experience.

Usage

Warning

Not all terminals work perfectly with ANSI codes. Ideally you should use xterm-256color.

Note

Terminal themes can change colors, e.g. magenta might show up as yellow, but it is still using the magenta ANSI code.

Prerequisites

• Python version >=3.10
• A terminal emulator that accepts ANSI codes
• A terminal emulator that uses xterm-256color

Note

ANSi codes are not limited to xterm-256color, but they may still be limited to all features this package provides.

Tested Terminals on Linux

Terminal ($TERM)

• Konsole (xterm-256color) - no missing features
• Xterm (xterm) - no missing features
• Alacritty (alacritty) - blinking text does not work
• Kitty (xterm-kitty) - blinking text does not work

Colors

This package introduces the ability to print colors via name, id, rgb, and hex codes with a single function:

>>> from ansiplus import print_color
>>> print_color("my colored text", color=(100, 200, 255), bgcolor=198)
'my colored text'
>>> print_color("red text", color="red")
>>> print("hex color 'f06'", color="#f06")

Colors may also be manually printed:

>>> from ansiplus.ansi.colors import Fore
>>> print(f"{Fore.GREEN}green text{Fore.RESET}")

Rainbow & Random Colors

Text can be colored to resemble a rainbow:

>>> from ansiplus import print_color
>>> print_color("this text is rainbow colored", "rainbow")
'this text is rainbow colored'
>>> print_color("each character will be a random color", "random")
'each character will be a random color'

Warning

Using rainbow or random color option uses a lot of ANSI codes.

User Input

Along with colors, users can be prompted for input which can be colored:

>>> from ansiplus import input_color
>>> txt = input_color("example: ", color="blue")
>>> print(txt)
'my input'

Prompting input can also store history if you assign it to a variable:

>>> from ansiplus import NewPrompt
>>> ui = NewPrompt()
>>> ui.set_color("red")
>>> ui.set_prompt_color("green")
>>> ui.prompt("prompt class example: ")
>>> ui.history
['my text']
>>> ui.latest
'my text'
>>> ui.prompt("prompt class example 2: ", "yellow")
>>> ui.latest
'this text is yellow, but default is red'

Rainbow & Random Colors

Prompt foreground text can also be colored rainbow:

>>> from ansiplus import input_color
>>> input_color("this text is rainbow: ", prompt_color="rainbow")

Clearing Prompt Lines

After receiving user input, the line can be cleared:

from ansiplus import input_color
while True:
    input_color("forever input: ", clearline=True)

The above code sample will ask for input forever, after every input, the line will clear and the input will be prompted again on the same line.

Text Styles

This package includes several several styles that can be used:

>>> from ansiplus import print_style
>>> print_style("underline text", "underline")
'underline text'

Like colors, styles may also be used manually:

>>> from ansiplus.ansi.styles import BOLD, BOLD_RESET
>>> print(f"{BOLD}bold text{BOLD_RESET}")
'bold text'
>>>

More Functions

There are more ANSI codes featured beyond colors and styles, these could be viewed by using help(ansiplus) inside the python interpreter.
