Colorize Different

A tiny utility that patches Python's built-in str with convenient ANSI color / style helpers so you can write "hello".red() instead of juggling escape sequences or long constant concatenations. Inspired by the Rust text-colorizer crate — ergonomic, expressive, and surprisingly pleasant to type.

Why use this? — Isn't patching str un-Pythonic?

Patching builtins is a controversial choice, and at first glance it may look un-Pythonic. Libraries like colorama require you to import constants and build strings by concatenation:

# colorama style (typical)
from colorama import Fore, Style
print(Fore.RED + "error: " + Style.RESET_ALL + "something went wrong")

That works fine, but it forces you to manage constants and remember to reset, and your code quickly becomes noisy with + and RESET tokens.

With coloredstrings the color becomes a readable method on the string itself:

import coloredstrings
coloredstrings.patch()
print("error:".red(), "something went wrong")
coloredstrings.unpatch()

This reads more like natural prose and keeps color usage local to the value being displayed.

Quick start — example usage

To patch globally:

import coloredstrings

# Attach helpers to built-in str
coloredstrings.patch()

print("ok".green())                # green text
print("warn".yellow().bold())      # chained styles (color then bold)
print("bad".red(), "on green".on_green())

# 24-bit RGB:
print("custom".rgb(123, 45, 200))

# 256-color:
print("teal-ish".color256(37))

# When you're done (optional) remove the patched methods:
coloredstrings.unpatch()

To patch locally (inside a function or a context):

import coloredstrings

def perror(message: str):
    with coloredstrings.patched():
        print(message.red())

@coloredstrings.patched
def log_info(message: str):
    colored = "INFO".blue()
    print(f"[{colored}]: {message}")

log_info("Downloaded image.")
perror("file not found!")

API (high level)

• patch() — attach methods to str

• unpatch() — remove the attached methods

• patched() - automatically calls patch() and unpatch() in a given context

• Color/style methods attached to str (call on any string):

  • Foreground colors: red(), green(), yellow(), blue(), magenta(), cyan(), white(), black(), bright_red()
  • Styles: bold(), dim(), italic(), underline(), inverse()
  • Background helpers: on_red(), on_green()
  • 24-bit color: rgb(r, g, b)
  • 256-color: color256(idx)

---

Installation

pip install git+https://github.com/samedit66/coloredstrings.git

I'll soon upload it to PyPi🙃.

Limitations

Under the hood coloredstrings uses forbiddenfruit package, as a result it also has the same limitations:

Forbbiden Fruit is tested on CPython 3.7-3.13. Since Forbidden Fruit is fundamentally dependent on the C API, this library won't work on other python implementations, such as Jython, pypy, etc.
