Features

• No more manual discovery of validators, automated registration and lookup process, cleaned lots of code on this one!

• New Validator: Accepted - The field under validation must be yes, on, 1, or true. This is useful for validating "Terms of Service" acceptance.

• New Validator: Alpha - Only allows alphabetic characters

• New Validator: RequiredUnless with validation data as a struct literal { anotherField:value, ... } - The field under validation must be present and not empty unless the anotherfield field is equal to the passed value.

• New Validator: RequiredIf with validation data as a struct literal { anotherField:value, ... } - The field under validation must be present and not empty if the anotherfield field is equal to the passed value.

• Accelerated validation by removing type checks. ACF chokes on interface checks

Improvements

• Consistency on all validators to ignore null or empty values except the Required validator

• Formatting consistencies

• Improve error messages to describe better validation

• Get away from evaluate() instead use invoke()
