Checker Full — Kv

At its core, a KV Checker is a utility that scans a file, string, or database stream to verify that key-value pairs adhere to a specific syntax. The "Full" modifier elevates this tool from a basic linter to a complete auditing solution.

A KV Checker Full typically performs four levels of validation: kv checker full

In short, a "full" check leaves no stone unturned. It moves beyond "Is this valid?" to "Is this usable, efficient, and secure?" At its core, a KV Checker is a

If you need a basic KV checker for .env files or a small JSON store, here's a minimal example: In short, a "full" check leaves no stone unturned

import json
import os
def check_kv(data, required_rules):
"""Validate key-value pairs against a set of rules."""
errors = []
for key, expected_type in required_rules.items():
if key not in data:
errors.append(f"Missing key: key")
elif not isinstance(data[key], expected_type):
errors.append(f"Type mismatch for key: expected expected_type.name, got type(data[key]).name")
return errors
Run the checker on production.kv vs staging.kv. The full tool can output a unified diff showing which keys are missing, new, or have conflicting value types.
The checker iterates through each rule and applies it to the actual data. It collects errors without stopping (to report all issues at once).
