NAME

List::Objects::WithUtils - Object interfaces to lists with useful methods

SYNOPSIS

use List::Objects::WithUtils;

my $array = array(qw/ aa Ab bb Bc bc /);

my @upper = $array->grep(
    sub { $_[0] =~ /^b/i }
  )->map(
    sub { uc $_[0] }
)->uniq->all;  # @upper = ( 'BB', 'BC' )


my $hash  = hash( foo => 'bar', snacks => 'cake' );

$hash->set( foobar => 'baz', pie => 'tasty' );

my @matching = $hash->keys->grep(sub { $_[0] =~ /foo/ })->all;

if ( $hash->keys->any_items eq 'snacks' ) {
  ...    
}

DESCRIPTION

A small set of roles and classes defining an object-oriented interface to Perl hashes and arrays. Originally derived from Data::Perl.

Some commonly used functions from List::Util, List::MoreUtils, and List::UtilsBy are conveniently provided as methods.

See:

List::Objects::WithUtils::Role::Array

List::Objects::WithUtils::Role::WithJunctions

List::Objects::WithUtils::Role::Hash

array is imported from List::Objects::WithUtils::Array and creates a new ARRAY-type object. Behavior is defined by List::Objects::WithUtils::Role::Array; look there for documentation on available methods.

hash is imported from List::Objects::WithUtils::Hash; see List::Objects::WithUtils::Role::Hash for documentation.

Why another object-oriented list module?

There are a fair few object-oriented approaches to lists on CPAN, none of which were quite what I needed. Data::Perl comes the closest -- but is primarily targetting MooX::HandlesVia and cannot guarantee a reasonably stable API (and I don't need the other data types).

This module aims to provide a consistent, natural interface to hashes and arrays exclusively, with convenient access to common tools. The interface is expected to remain stable; methods may be added but are not expected to be removed (or experience incompatible interface changes, barring serious bugs).
