NAME ^

Validation::Interface - Powerful Data Validation Framework

VERSION ^

version 0.01_01

SYNOPSIS ^

    use Validation::Interface::Builder;

    my  $params  = {username => 'admin', password => 's3cret'};
    my  $builder = Validation::Interface::Builder->new(params => $params);

        # check username parameter
        $builder->check('username')->required->between('5-255');
        $builder->filters(['trim', 'strip']);

        # check password parameter
        $builder->check('password')->required->between('5-255')->min_symbols(1);
        $builder->filters(['trim', 'strip']);

        # validate parameters
        die $builder->errors unless $builder->validate;

DESCRIPTION ^

Validation::Interface is a scalable data validation library with interfaces for applications of all sizes. The most common usage of Validation::Interface is to transform class namespaces into data validation domains where consistency and reuse are primary concerns. Validation::Interface provides an extensible framework for defining reusable data validation rules. It ships with a complete set of pre-defined validations and filters referred to as directives.

Validation::Interface is a complete rewrite of its predecessor, Validation::Class, bringing a better implementation and object-orientation; as well as applying the lessons learned and supporting new usages. The main features are; hierarchical data handling; trait-like validation rules; validation templates; pre/post input filtering; class inheritance handling; overriding default error messages; creating custom validators; creating custom input filters; localization; and more. Validation::Interface promotes DRY (don't repeat yourself) code. The main benefit in using Validation::Interface is that the architecture is designed to increase the consistency of data input handling.
