Orval (beta)

A Python package containing a small set of utility functions not found in Python's standard library. It is lightweight, written in pure Python, and has no dependencies.

Why is it named orval? Because other utility names are boring and it's a tasty Belgian beer 🤘❤️

🚀 Using

To install this package, run:

pip install orval

String utils

from orval import kebab_case
kebab_case("Great Scott")
# Output: great-scott
kebab_case("Gréat Scött")

# Slightly different from kebab_case. It does not allow Unicode characters.
# Slugify is well-suited for URL paths or infrastructure resource names (e.g., database names).
from orval import slugify
slugify("Great scott !! 🤘")
# Output: great-scott
slugify("Gréat scött !! 🤘")
# Output: great-scott

from orval import camel_case
camel_case(" Great scott ")
# Output: greatScott

from orval import snake_case
snake_case(" Great  Scott ")
# Output: great_scott

from orval import train_case
train_case(" content type ")
# Output: Content-Type

from orval import chunkify
chunkify([1, 2, 3, 4, 5, 6], 2)

list(flatten([[1, 2], [3, [4]]]))
# Output: [1, 2, 3, 4]
list(flatten([[1, 2], [3, [4]]], depth=1))
# Output: [1, 2, 3, [4]]
