Horus

Horus is a recursive data-structure validator. It walks nested dicts, lists, tuples and scalars and checks every node against rule sets of regex patterns, reporting compliance with human-readable messages and the exact path of each violation.

Installation

pip install wedjat

The package is distributed as wedjat on PyPI but imported as Horus.

Usage

from Horus import Horus, newType

validator_rules = {
    "name": {"first": "Empty,EnSmCp", "last": "Empty,EnSmCp"},
    "age": "Empty,Dg",
    "hoppies": [{"hoppy": "Empty,EnSmCp"}],
    "trips": ["Empty,EnSmCp"],
}

validator_input = {
    "name": {"first": "Ahmed", "last": "KamalELSaman"},
    "age": 35,
    "hoppies": [{"hoppy": "Cycle"}, {"hoppy": "Swim"}],
    "trips": ["Germany"],
}

Horus.eye(validator_rules, validator_input)

Each rule is a comma-separated list of rule names. The leading names are refuse patterns (input that matches is rejected) and the final name is the accept pattern (input that does not match is rejected). Rules are defined in validator_rules.py as {name: {"pattern": ..., "message": ...}}.
