Valida...Length(3pm)

✨ Validation::Class::Directive::Length — the manual page but make it a group chat ✨

okay bestie so this is Validation::Class::Directive::Length, a Perl module, from the Validation::Class family, sitting in the 3pm manual section (that's Perl Module Pages, iykyk). It's the Length directive — the one that does a vibe check on how long your stuff is. 💅

🌈 VERSION

version 7.900059

that's the version, no cap. write it down. 📝

🎀 SYNOPSIS

here's how you actually use it, bestie — copy this exactly:

use Validation::Class::Simple;

my $rules = Validation::Class::Simple->new(
    fields => {
        security_pin => {
            length => 4
        }
    }
);

# set parameters to be validated
$rules->params->add($parameters);

# validate
unless ($rules->validate) {
    # handle the failures
}

so you're building a rules object, you're declaring a field called security_pin with length => 4, you're feeding it your $parameters, and then you call $rules->validate — and if it comes back false, that's your cue to handle the failures. simple. iconic. 🫶
