Data::Perl - Base classes wrapping fundamental Perl data types.
use Data::Perl;
my $array = array(1,2,3, qw/a b c/);
$array->count; # 6
my @elements = $array->grep(sub {/b/}); # (b)
my $hash = hash(a => 1, b => 2);
$hash->keys; # ('a', 'b');
my $number = number(5);
$number->add(10); # 15
my $string = string("foo\n");
$string->chomp; # return 1, chomps string
my $counter = counter();
$counter->inc; # counter is now 1
my $sub = code(sub { 'foo' });
$sub->execute; # returns 'foo'
$foo
Data::Perl is a collection of classes that wrap fundamental data types that
exist in Perl. These classes and methods as they exist today are an attempt to
mirror functionality provided by Moose's Native Traits. One important thing to
note is all classes currently do no validation on constructor input.
Data::Perl is a container class for the following classes:
- Data::Perl::Collection::Hash
- Data::Perl::Collection::Array
- Data::Perl::String
- Data::Perl::Number
- Data::Perl::Counter
- Data::Perl::Bool
- Data::Perl::Code
The API provided by these modules is as of now considered alpha and undecided.
The API WILL change. If you are writing code that you will not touch
again for years, do not use this until this warning is removed.
Data::Perl exports helper constructor functions to interface with the above
classes:
- hash(key, value, ...)
Returns a Data::Perl::Collection::Hash object initialized with
the optionally passed in key/value args.
- array(@args)
Returns a Data::Perl::Collection::Array object initialized
with the optionally passed in values.
- string($arg)
Returns a Data::Perl::String object initialized with the
optionally passed in scalar arg.
- number($arg)
Returns a Data::Perl::Number object initialized with the
optionally passed in scalar arg.
- counter($arg)
Returns a Data::Perl::Counter object initialized with the
optionally passed in scalar arg.
- bool($arg)
Returns a Data::Perl::Bool object initialized with the truth
value of the passed in scalar arg.
- code($arg)
Returns a Data::Perl::Code object initialized with the
optionally passed in scalar coderef as an arg.
Much thanks to the Moose team for their work with native traits, for which much
of this work is based.
