apathetic-schema 0.1.3

Type-based validation for dict-based configs.

Apathetic Python Schema 🧩

📘 Roadmap · 📝 Release Notes

Lightweight validation for dict-based configs.
Types can be schema too.

Apathetic Python Schema validates dict-based data structures (configs, usually from JSONC/JSON/TOML) using Python TypedDicts used for mypy/pyright. No need for separate schema definitions — your type annotations are your schema.

[!NOTE] Heads up: the AI cooked dinner. It's edible, but watch your step.
Detailed bug reports welcome.

Quick Start

from apathetic_schema import apathetic_schema, ApatheticSchema_ValidationSummary
from apathetic_utils import schema_from_typeddict
from typing import TypedDict
from pathlib import Path
import json

# Define your config schema using TypedDict
class AppConfig(TypedDict):
    name: str
    version: str
    port: int
    debug: bool

# Load config from JSON
with Path("config.json").open() as f:
    config = json.load(f)

# Validate against TypedDict schema
summary = ApatheticSchema_ValidationSummary(valid=True, errors=[], strict_warnings=[], warnings=[], strict=False)
schema = schema_from_typeddict(AppConfig)

is_valid = apathetic_schema.check_schema_conformance(
    config,
    schema,
    "in configuration file",
    strict_config=False,
    summary=summary,
)

if not summary.valid:
    print("Validation errors:", summary.errors)
    print("Warnings:", summary.warnings)
