NAME

Data::NestedParams - entry[title]=foo&tags[]=art&tags[]=modern

SYNOPSIS

    use Data::NestedParams;

    my $expanded = expand_nested_params(
        [
            'entry[title]' => 'foo',
            'tags[]' => 'art',
            'tags[]' => 'modern',
        ]
    );
    # $expanded = { entry => {title => 'foo'}, tags => ['art', 'modern'] };

DESCRIPTION

Ruby on Rails has a nice feature to create nested parameters that help with the organization of data in a form - parameters can be an arbitrarily deep nested structure.

The way this structure is denoted is that when you construct a form the field names have a special syntax which is parsed.
