    FormValidator::Lite->load_constraints(qw/Japanese/);

    my $q = CGI->new();
    my $validator = FormValidator::Lite->new($q);
    my $res = $validator->check(
        name => [qw/NOT_NULL/],

    }
    if ($validator->has_error) {
        ...
    }

    # in your tmpl
    <ul>
    ? for my $msg ($validator->get_error_messages) {
        <li><?= $msg ?></li>
    ? }
    </ul>
    

DESCRIPTION

FormValidator::Lite is simple, fast implementation for form validation.

IT'S IN BETA QUALITY. API MAY CHANGE IN FUTURE.

WHY NOT FormValidator::Simple?

Yes, I know. This module is very similar with FV::S.

But, FormValidator::Simple is too heavy for me. FormValidator::Lite is fast!

                            Rate FormValidator::Simple   FormValidator::Lite

HOW TO WRITE YOUR OWN CONSTRAINTS

    http parameter comes from $_
    validator args comes from @_
