Hey dear #AlchemistFriends! I’m creating a validation engine , in order to put several day-to-day validation rules all together!!!
If you folks could take a look real quick and provide me some feedback, that would be just fantastic to listen from you
Some validation rules for instance: Email, Credit Card, Barcode, IBAN, WordCount, PostalCode (us, uk, br…), CountryCode, MacAddress… and +65 other ;- )
P.S.: I’m very-very-very new to the Elixir ecosystem. Literally just 2 weeks learning the language & writing code. Please be a bit merciful (hehe). Thanks for your understanding.
Just to point out, while it is deprecated it is perfectly valid email:
foo(@)@baz.com
And I believe your regex will mark it as invalid. You have 2 options how to approach such data as this one:
Strictly follow RFC2822 (but for example use flags to disallow some features like comments)
Use HTML5 default regex, which is not correct, but at least it will match the same expectations as browser does
Otherwise it ends somewhere in between and can be a little bit confusing (ignoring fact that such long regex is very easy to abuse and force engine to do matching in O(n^2)).
EDIT:
Also it is hard to tell in your alphanumeric/alpha/etc. work within Unicode groups or not. Is string ٠ numeric or not? This character is U+0660 Arabic-Indic Digit Zero, so it is digit, but I think that You do not expected that.
