A small, zero-dependency toolkit for validating and formatting the kinds of data that show up in almost every form or import script: email addresses, phone numbers, URLs, IBANs, credit card numbers, postal codes and slugs.
It exists because most projects end up copy-pasting the same handful of regexes and checksum functions over and over. This gem collects the ones worth reusing into one place, with tests and no runtime dependencies.
This is a Ruby port of datacheck-kit
(originally written for npm, also on PyPI
and Packagist) — same
functionality, adapted to Ruby conventions (?-suffixed predicates, nil
instead of other languages' null-likes).
