declaro 0.0.1

The Functional Python Stack - pure functions, typed data, no class magic

Declaro

The Functional Python Stack

Pure functions. Typed data. No class magic.

Vision

Declaro is a collection of tools for developers who believe:

• Data is just data - Dicts and TypedDicts, not objects with hidden state
• Functions transform data - Pure functions with no side effects
• Types should be explicit - Declared upfront, enforced everywhere
• Testing should be trivial - Same input, same output, always

Packages

Package	Description	Status
declaro-persistum	Schema-first database toolkit	In development
declaro-ximenez	Type enforcement with memorable errors	Planned
declaro-api	FastAPI integration	Planned

Installation

# Install everything
pip install declaro[all]

# Or pick what you need
pip install declaro-persistum
pip install declaro-ximenez
pip install declaro-api

Philosophy

# Not this (classes, state, magic)
class User(BaseModel):
    email: str

    @validator("email")
    def validate_email(cls, v):
        ...

# This (data, functions, clarity)
User = TypedDict("User", {"email": str})

def validate_user(user: dict) -> list[Error]:
    return check_email(user.get("email", ""))
