didactic 0.4.0

Pydantic-class API on top of panproto: GATs, lenses, and VCS.

didactic

A typed-data library for Python on top of panproto.

Authoring is class-based and looks like Pydantic. Underneath, every Model corresponds to a panproto Theory, every value to a panproto Schema, and every transformation between Models to a panproto Lens.

This is the core distribution. Three sibling distributions (didactic-pydantic, didactic-settings, didactic-fastapi) contribute submodules under didactic.<name>.

Install

didactic targets Python 3.14 and panproto 0.43+.

pip install didactic

Quickstart

import didactic.api as dx


class User(dx.Model):
    """A user record."""

    id: str
    email: str
    display_name: str = ""


u = User(id="u1", email="a@b.c")
u2 = u.with_(display_name="Alice")
