Lightweight utilities for converting strings between common cases

Magic Case

Lightweight utilities for converting strings between common cases, built on a simple BaseCase abstraction.

• Cases: SnakeCase, CamelCase, PascalCase, KebabCase, UpperCase, SentenceCase, TitleCase
• Composable: Construct from raw strings or from another case class
• Zero deps: No runtime dependencies

Installation

Using uv (recommended):

uv add magic-case>=0.2.0

Standard pip:

pip install "magic-case>=0.2.0"

Quick start

from magic_case import SnakeCase, CamelCase, PascalCase, KebabCase, UpperCase, SentenceCase, TitleCase

print(SnakeCase('hello_world').get())     # hello_world
print(CamelCase('helloWorld').get())      # helloWorld
print(PascalCase('HelloWorld').get())     # HelloWorld
print(KebabCase('hello-world').get())     # hello-world
print(UpperCase('hello_world').get())     # HELLO_WORLD
print(SentenceCase('hello world').get())  # Hello world
print(TitleCase('hello world').get())     # Hello World

Convert between cases

Construct from another case to re-render with a different style:

from magic_case import SnakeCase, CamelCase, PascalCase

snake = SnakeCase('hello_world')
print(CamelCase(snake).get())   # helloWorld
print(PascalCase(snake).get())  # HelloWorld

API

• BaseCase
  • words: List[str] normalized to lowercase
  • get() -> str returns the rendered string (same as str(instance))
  • Subclasses implement:
    • _split_into_words(text: str) -> List[str]
    • __str__(self) -> str
• Concrete cases
  • SnakeCase, CamelCase, PascalCase, KebabCase, UpperCase, SentenceCase, TitleCase

Requirements

• Python 3.8+
