Quick Start

1. Basic Validation (Python)

from regexto_validators import validate, test

# 1. Quick boolean test (substring match)
test('email', 'contact me at [e-mail]')   # → True
test('email', 'invalid-email')                      # → False

# 2. Strict full-string validation
is_valid = validate('ipv4', '192.168.1.1')          # → True

2. Smart Type Auto-Detection

Pass an unknown string, and the validator will identify matching formats:

from regexto_validators import detect

matches = detect('0x742d35Cc6634C0532925a3b844Bc454e4438f44e')
# → [{'pattern': {'slug': 'ethereum-address', ...}, 'matchType': 'full', 'coverage': 1.0}]
