colrs 0.1.3

A simple and elegant Python library for terminal text coloring.

colrs 🎨

A radically simple Python library for coloring your terminal output.

colrs takes a different approach to terminal coloring. Instead of wrapping your print statements in special functions, you activate it once, and your standard print and input functions become color-aware.

---

Philosophy

The core idea is absolute simplicity. No new function names to remember for printing. Just activate the magic and write your code as you normally would, but with added superpowers.

• Activate: act()
• Use print and input normally: Add colors with tags or keyword arguments.
• Deactivate: unact()
• Show Animations: loading()

This is the core public API, designed for simplicity and power.

Installation

To install the library:

pip install colrs

How to Use

The usage is designed to be as intuitive as possible. You import act and unact, and wrap the code you want to be color-aware.

Basic Example

from colrs import act, unact

# This print is normal
print("This is default terminal text.")

# Activate the color patching
act()

# Now, print() and input() are super-powered!
print("This is a <green>green text</> using inline tags.")
print("This is red.", color="red")
print("This is blue on a yellow background.", color="blue", bg_color="yellow")

name = input("What's your name? ", color="cyan", inp_color="magenta")
print(f"Hello, {name}!")

# It's good practice to deactivate when you're done
unact()

print("And we're back to normal.")

Using print() with act()

Once act() is called, print() can accept two new keyword arguments: color and bg_color.

More powerfully, you can use inline tags for fine-grained control.

act()

# Simple tags
print("<red>This will be red.</red>") # The closing tag is optional

# Nested tags
print("<yellow>This is yellow with <blue>blue text</blue> inside.</yellow>")

# Background colors
print("<white,bg_red> White text on a red background. </>") # </> resets all

unact()

Using input() with act()

The patched input() can color three things separately:

1. The prompt text (color and bg_color arguments, or tags).
2. The text the user types (inp_color argument).

act()

# The prompt will be yellow, and the user's typing will be cyan
username = input("Enter username: ", color="yellow", inp_color="cyan")

# You can also use tags in the prompt
password = input("<red>Enter password:</red> ", inp_color="red")

unact()

Why colrs?

If you want a coloring library that "just works" in the background without forcing you to change your coding habits, colrs is for you. It's designed for scripts and applications where you want to enable colors globally with minimal code changes.
