autobox::Core - Provide core functions to autoboxed scalars, arrays and hashes.



  use autobox::Core;

  "Hello, World\n"->uc->print;

  my @list = (1, 5, 9, 2, 0, 4, 2, 1);

  # works with references too!
  my $list = [1, 5, 9, 2, 0, 4, 2, 1];

  my %hash = (
      grass => green,
      apple => red,
      sky   => blue,

  [10, 20, 30, 40, 50]->pop->say;
  [10, 20, 30, 40, 50]->shift->say;

  my $lala = "Lalalalala\n";
  "chomp: "->concat($lala->chomp, " ", $lala)->say;

  my $hashref = { foo => 10, bar => 20, baz => 30, qux => 40 };

  print "hash keys: ", $hashref->keys->join( ), "\n"; # or if you prefer...
  print "hash keys: ", join  , $hashref->keys(), "\n"; # or
  print "hash keys: "; $hashref->keys->say;


The autobox module promotes Perl’s primitive types (literals (strings and numbers), scalars, arrays and hashes) into first-class objects. However, autobox does not provide any methods for these new classes.

autobox::CORE provides a set of methods for these new classes. It includes almost everything in perlfunc, some things from Scalar::Util and List::Util, and some Perl 5 versions of methods taken from Perl 6.

With autobox::Core one is able to change this:

        print join(" ", reverse(split(" ", $string)));

to this:

        use autobox::Core;

        $string->split(" ")->reverse->print;

Likewise you can change this:

        my $array_ref = [qw(fish dog cat elephant bird)];

        push @$array_ref, qw(snake lizard giraffe mouse);

to this:

        use autobox::Core;
        my $array_ref = [qw(fish dog cat elephant bird)];

        $array_ref->push( qw(snake lizard giraffe mouse));

autobox::Core makes it easier to avoid parentheses pile ups and messy dereferencing syntaxes.

autobox::Core is mostly glue. It presents existing functions with a new interface, while adding few extra. Most of the methods read like sub hex { CORE::hex($_[0]) }. In addition to built-ins from perlfunc that operate on hashes, arrays, scalars, and code references, some Perl 6-ish things have been included, and some keywords like foreach are represented too.

    What’s Implemented?

o Many of the functions listed in perlfunc under the headings:
o Functions for real @ARRAYs,
o Functions for real %HASHes,
o Functions for list data,
o Functions for SCALARs or strings

plus a few taken from other sections and documented below.

o Some methods from Scalar::Util and List::Util.
o Some things expected in Perl 6, such as last (last_idx), elems, and curry.
o flatten explicitly flattens an array.
String Methods

String methods are of the form my $return = $string->method(@args). Some will act on the $string and some will return a new string.

Many string methods are simply wrappers around core functions, but there are additional operations and modifications to core behavior.

Anything which takes a regular expression, such as split and m, usually take it in the form of a compiled regex (qr//). Any modifiers can be attached to the qr normally. Bare strings may be used in place of regular expressions, and Perl will compile it to a regex, as usual.

These built in functions are implemented for scalars, they work just like normal: chomp, chop,chr crypt, index, lc lcfirst, length, ord, pack, reverse (always in scalar context), rindex, sprintf, substr, uc ucfirst, unpack, quotemeta, vec, undef, split, system, eval.

In addition, so are each of the following:



Concatenates $string2 to $string1. This corresponds to the . operator used to join two strings. Returns the joined strings.


Removes whitespace from the beginning and end of a string.

   " \t  \n  \t  foo  \t  \n  \t  "->strip;    # foo

This is redundant and subtly different from trim which allows for the removal of specific characters from the beginning and end of a string.


Removes whitespace from the beginning and end of a string. trim can also remove specific characters from the beginning and the end of string.

       hello->trim;                   # hello
   *+* hello *+*->trim("*+");         #  hello 
    *+* hello *+*->trim("*+");        #  *+* hello


Just like trim but it only trims the left side (start) of the string.

       hello->ltrim;                  # hello
   *+* hello *+*->ltrim("*+");        #  hello *+*


Just like trim but it only trims the right side (end) of the string.

   hello   ->rtrim;                   # hello
   *+* hello *+*->rtrim("*+");        # *+* hello 


    my @split_string = $string->split(qr/.../);
    my @split_string = $string->split( );

A wrapper around split. It takes the regular expression as a compiled regex, or a string which Perl parses as a regex.

   print "10, 20, 30, 40"->split(qr{, ?})->elements, "\n";
   "hi there"->split(qr/ */);           # h i t h e r e

The limit argument is not implemented.


title_case converts the first character of each word in the string to upper case.

   "this is a test"->title_case;        # This Is A Test


    my $centered_string = $string->center($length);
    my $centered_string = $string->center($length, $character);

Centers $string between $character. $centered_string will be of length $length, or the length of $string, whichever is greater.

$character defaults to .

    say "Hello"->center(10);        # "   Hello  ";
    say "Hello"->center(10, -);   # "---Hello--";

center() will never truncate $string. If $length is less than $string->length it will just return $string.

    say "Hello"->center(4);        # "Hello";


    my $output = $string->qx;

Runs $string as a command just enclosing it backticks, as in `$string`.


    if( $foo->nm(qr/bar/) ) {
        say "$foo did not match bar";

Negative match. Corresponds to !~. Otherwise works in the same way as m().


    if( $foo->m(qr/bar/) ) {
        say "$foo matched bar";

    my $matches = $foo->m( qr/(\d*) (\w+)/ );
    say $matches->[0];
    say $matches->[1];

Works the same as m//, but the regex must be passed in as a qr//.

m returns an array reference so that list functions such as map and grep may be called on the result. Use elements to turn this into a list of values.

  my ($street_number, $street_name, $apartment_number) =
      "1234 Robin Drive #101"->m( qr{(\d+) (.*)(?: #(\d+))?} )->elements;

  print "$street_number $street_name $apartment_number\n";


  my $string = "the cat sat on the mat";
  $string->s( qr/cat/, "dog" );
  $string->say;                 # the dog sat on the mat

String substitution. Works similarly to s///. In boolean context, it returns true/false to indicate whether the substitution succeeded. if, ?:, !, and so on, all provide boolean context. It either fails or succeeds, having replaced only one occurrence on success — it doesn’t replace globally. In scalar context other than boolean context, it returns the modified string (incompatible change, new as of v 1.31).



Assigns undef to the $string.


    my $is_defined = $string->defined;

    if( not $string->defined ) {
        # give $string a value...

defined tests whether a value is defined (not undef).


    my $repeated_string = $string->repeat($n);

Like the x operator, repeats a string $n times.

    print 1->repeat(5);     # 11111
    print "\n"->repeat(10); # ten newlines

I/O Methods

These are methods having to do with input and ouptut, not filehandles.



Prints a string or a list of strings. Returns true if successful.


Like print, but implicitly appends a newline to the end.


Boolean Methods

Methods related to boolean operations.


and corresponds to &&. Returns true if both operands are true.

        if( $a->and($b) ) {


not corresponds to !. Returns true if the subject is false.

        if( $a->not ) {


or corresponds to ||. Returns true if at least one of the operands is true.

        if( $a->or($b) ) {


xor corresponds to xor. Returns true if only one of the operands is true.

        if( $a->xor($b) ) {

Number Related Methods

Methods related to numbers.

The basic built in functions which operate as normal : abs, atan2, cos, exp, int, log, oct, hex, sin, and sqrt.

The following operators were also included:


    # $number is smaller by 1.

dec corresponds to ++. Decrements subject, will decrement character strings too: ’b’ decrements to ’a’.


inc corresponds to ++. Increments subject, will increment character strings too. ’a’ increments to ’b’.


mod corresponds to %.



pow returns $number raised to the power of the $exponent.

    my $result = $number->pow($expontent);
    print 2->pow(8);  # 256


    $is_a_number = $thing->is_number;

Returns true if $thing is a number as understood by Perl.

    12.34->is_number;           # true
    "12.34"->is_number;         # also true


    $is_positive = $thing->is_positive;

Returns true if $thing is a positive number.

0 is not positive.


    $is_negative = $thing->is_negative;

Returns true if $thing is a negative number.

0 is not negative.


    $is_an_integer = $thing->is_integer;

Returns true if $thing is an integer.

    12->is_integer;             # true
    12.34->is_integer;          # false


A synonym for is_integer.


    $is_a_decimal_number = $thing->is_decimal;

Returns true if $thing is a decimal number.

    12->is_decimal;             # false
    12.34->is_decimal;          # true
    ".34"->is_decimal;          # true

Reference Related Methods

The following core functions are implemented.

tie, tied, ref, vec.

tie, tied, and undef don’t work on code references.

Array Methods

Array methods work on both arrays and array references:

  my $arr = [ 1 .. 10 ];


  my @arr = ( 1 .. 10 );

List context forces methods to return a list:

  my @arr = ( 1 .. 10 );
  print join  -- , @arr->grep(sub { $_ > 3 }), "\n";

Likewise, scalar context forces methods to return an array reference.

As scalar context forces methods to return a reference, methods may be chained

  my @arr = ( 1 .. 10 );
  @arr->grep(sub { $_ > 3 })->min->say;  # "4\n";

These built-in functions are defined as methods:

pop, push, shift, unshift, delete, undef, exists, bless, tie, tied, ref, grep, map, join, reverse, and sort, each.

As well as:


Deletes a specified value from the array.

  $a = 1->to(10);
  $a->vdelete(3);         # deletes 3
  $a->vdelete(2)->say;    # "1 4 5 6 7 8 9 10\n"


Removes all duplicate elements from an array and returns the new array with no duplicates.

   my @array = qw( 1 1 2 3 3 6 6 );
   @return = @array->uniq;    # @return : 1 2 3 6


Returns the first element of an array for which a callback returns true:

  $arr->first(sub { qr/5/ });


Returns the largest numerical value in the array.

   $a = 1->to(10);
   $a->max;           # 10


Returns the smallest numerical value in the array.

   $a = 1->to(10);
   $a->min;           # 1


Returns the mean of elements of an array.

   $a = 1->to(10);
   $a->mean;          # 55/10


Returns the variance of the elements of an array.

   $a = 1->to(10);
   $a->var;           # 33/4


Returns the standard variance.

  $a = 1->to(10);
  $a->svar;                     # 55/6


Returns the element at a specified index. This function does not modify the original array.

   $a = 1->to(10);
   $a->at(2);                   # 3

size, elems, length

size, elems and length all return the number of elements in an array.

   my @array = qw(foo bar baz);
   @array->size;   # 3

elements, flatten

    my @copy_of_array = $array->flatten;

Returns the elements of an array ref as an array. This is the same as @{$array}.

Arrays can be iterated on using for and foreach. Both take a code reference as the body of the for statement.



Calls &code on each element of the @array in order. &code gets the element as its argument.

    @array->foreach(sub { print $_[0] });  # print each element of the array



Like foreach, but &code is called with the index, the value and the array itself.

    my $arr = [ 1 .. 10 ];
    $arr->for(sub {
        my($idx, $value) = @_;
        print "Value #$idx is $value\n";


    my $sum = @array->sum;

Adds together all the elements of the array.


Returns the number of elements in array that are eq to a specified value:

  my @array = qw/one two two three three three/;
  my $num = @array->count(three);  # returns 3

to, upto, downto

to, upto, and downto create array references:

   1->to(5);      # creates [1, 2, 3, 4, 5]
   1->upto(5);    # creates [1, 2, 3, 4, 5]
   5->downto(5);  # creates [5, 4, 3, 2, 1]

Those wrap the .. operator.

<B>NoteB> while working with negative numbers you need to use () so as to avoid the wrong evaluation.

  my $range = 10->to(1);        # this works
  my $range = -10->to(10);      # wrong, interpreted as -( 10->to(10) )
  my $range = (-10)->to(10);    # this works


Returns the first element from @list. This differs from shift in that it does not change the array.

    my $first = @list->head;


Returns all but the first element from @list.

    my @list = qw(foo bar baz quux);
    my @rest = @list->tail;  # [ bar, baz, quux ]

Optionally, you can pass a number as argument to ask for the last $n elements:

    @rest = @list->tail(2); # [ baz, quux ]


Returns a list containing the elements from @list at the indices @indices. In scalar context, returns an array reference.

    # Return $list[1], $list[2], $list[4] and $list[8].
    my @sublist = @list->slice(1,2,4,8);


range returns a list containing the elements from @list with indices ranging from $lower_idx to $upper_idx. It returns an array reference in scalar context.

    my @sublist = @list->range( $lower_idx, $upper_idx );


    my $index = @array->last_index(qr/.../);

Returns the highest index whose element matches the given regular expression.

    my $index = @array->last_index(\&filter);

Returns the highest index for an element on which the filter returns true. The &filter is passed in each value of the @array.

    my @things = qw(pear poll potato tomato);
    my $last_p = @things->last_index(qr/^p/); # 2

Called with no arguments, it corresponds to $#array giving the highest index of the array.

    my $index = @array->last_index;


Works just like last_index but it will return the index of the first matching element.

    my $first_index = @array->first_index;    # 0

    my @things = qw(pear poll potato tomato);
    my $last_p = @things->first_index(qr/^t/); # 3


    my $value = $array->at($index);

Equivalent to $array->[$index].

Hash Methods

Hash methods work on both hashes and hash references.

The built in functions work as normal:

delete, exists, keys, values, bless, tie, tied, ref, undef,

at, get

    my @values = %hash->get(@keys);

Returns the @values of @keys.



Overlays %other_hash on top of %hash.

   my $h = {a => 1, b => 2};
   $h->put(b => 99, c => 3);    # (a => 1, b => 99, c => 3)


Synonym for put.


Like foreach but for hash references. For each key in the hash, the code reference is invoked with the key and the corresponding value as arguments:

  my $hashref = { foo => 10, bar => 20, baz => 30, quux => 40 };
  $hashref->each(sub { print $_[0],  is , $_[1], "\n" });


  my %hash = ( foo => 10, bar => 20, baz => 30, quux => 40 );
  %hash->each(sub { print $_[0],  is , $_[1], "\n" });

Unlike regular each, this each will always iterate through the entire hash.

Hash keys appear in random order that varies from run to run (this is intentional, to avoid calculated attacks designed to trigger algorithmic worst case scenario in perl’s hash tables).

You can get a sorted foreach by combining keys, sort, and foreach:

   %hash->keys->sort->foreach(sub {
      print $_[0],  is , $hash{$_[0]}, "\n";



Works as lock_keys in Hash::Util. No more keys may be added to the hash.


Takes a list of hash keys and returns the corresponding values e.g.

  my %hash = (
      one   => two,
      three => four,
      five  => six

  print %hash->slice(qw(one five))->join( and ); # prints "two and six"


Exchanges values for keys in a hash:

    my %things = ( foo => 1, bar => 2, baz => 5 );
    my %flipped = %things->flip; # { 1 => foo, 2 => bar, 5 => baz }

If there is more than one occurrence of a certain value, any one of the keys may end up as the value. This is because of the random ordering of hash keys.

    # Could be { 1 => foo }, { 1 => bar }, or { 1 => baz }
    { foo => 1, bar => 1, baz => 1 }->flip;

Because references cannot usefully be keys, it will not work where the values are references.

    { foo => [ bar, baz ] }->flip; # dies


    my %hash = $hash_ref->flatten;

Dereferences a hash reference.

Code Methods

Methods which work on code references.

These are simple wrappers around the Perl core functions. bless, ref,

Due to Perl’s precedence rules, some autoboxed literals may need to be parenthesized. For instance, this works:

  my $curried = sub { ... }->curry();

This does not:

  my $curried = \&foo->curry();

The solution is to wrap the reference in parentheses:

  my $curried = (\&foo)->curry();


    my $curried_code = $code->curry(5);

Currying takes a code reference and provides the same code, but with the first argument filled in.

    my $greet_world = sub {
        my($greeting, $place) = @_;
        return "$greeting, $place!";
    print $greet_world->("Hello", "world");  # "Hello, world!"

    my $howdy_world = $greet_world->curry("Howdy");
    print $howdy_world->("Texas");           # "Howdy, Texas!"

    What’s Missing?

o File and socket operations are already implemented in an object-oriented fashion care of IO::Handle, IO::Socket::INET, and IO::Any.
o Functions listed in the perlfunc headings
o System V interprocess communication functions,
o Fetching user and group info,
o Fetching network info,
o Keywords related to perl modules,
o Functions for processes and process groups,
o Keywords related to scoping,

These things are likely implemented in an object oriented fashion by other CPAN modules, are keywords and not functions, take no arguments, or don’t make sense as part of the string, number, array, hash, or code API.


This section quotes four pages from the manuscript of Perl 6 Now: The Core Ideas Illustrated with Perl 5 by Scott Walters. The text appears in the book starting at page 248. This copy lacks the benefit of copyedit - the finished product is of higher quality.

A box is an object that contains a primitive variable. Boxes are used to endow primitive types with the capabilities of objects which essential in strongly typed languages but never strictly required in Perl. Programmers might write something like my $number = Int->new(5). This is manual boxing. To autobox is to convert a simple type into an object type automatically, or only conceptually. This is done by the language.

autoboxing makes a language look to programmers as if everything is an object while the interpreter is free to implement data storage however it pleases. Autoboxing is really making simple types such as numbers, strings, and arrays appear to be objects.

int, num, bit, str, and other types with lower case names, are primitives. They’re fast to operate on, and require no more memory to store than the data held strictly requires. Int, Num, Bit, Str, and other types with an initial capital letter, are objects. These may be subclassed (inherited from) and accept traits, among other things. These objects are provided by the system for the sole purpose of representing primitive types as objects, though this has many ancillary benefits such as making is and has work. Perl provides Int to encapsulate an int, Num to encapsulate a num, Bit to encapsulate a bit, and so on. As Perl’s implementations of hashes and dynamically expandable arrays store any type, not just objects, Perl programmers almost never are required to box primitive types in objects. Perl’s power makes this feature less essential than it is in other languages.

autoboxing makes primitive objects and they’re boxed versions equivalent. An int may be used as an Int with no constructor call, no passing, nothing. This applies to constants too, not just variables. This is a more Perl 6 way of doing things.

  # Perl 6 - autoboxing associates classes with primitives types:

  print 4.sqrt, "\n";

  print [ 1 .. 20 ].elems, "\n";

The language is free to implement data storage however it wishes but the programmer sees the variables as objects.

Expressions using autoboxing read somewhat like Latin suffixes. In the autoboxing mind-set, you might not say that something is made more mnemonic, but has been mnemonicified.

Autoboxing may be mixed with normal function calls. In the case where the methods are available as functions and the functions are available as methods, it is only a matter of personal taste how the expression should be written:

  # Calling methods on numbers and strings, these three lines are equivalent
  # Perl 6

  print sqrt 4;
  print 4.sqrt;

The first of these three equivalents assumes that a global sqrt() function exists. This first example would fail to operate if this global function were removed and only a method in the Num package was left.

Perl 5 had the beginnings of autoboxing with filehandles:

  use IO::Handle;
  open my $file, <, file.txt or die $!;
  $file->read(my $data, -s $file);

Here, read is a method on a filehandle we opened but never blessed. This lets us say things like $file->print(...) rather than the often ambagious print $file ....

To many people, much of the time, it makes more conceptual sense as well.

Reasons to Box Primitive Types

What good is all of this?
o Makes conceptual sense to programmers used to object interfaces as the way to perform options.
o Alternative idiom. Doesn’t require the programmer to write or read expressions with complex precedence rules or strange operators.
o Many times that parenthesis would otherwise have to span a large expression, the expression may be rewritten such that the parenthesis span only a few primitive types.
o Code may often be written with fewer temporary variables.
o Autoboxing provides the benefits of boxed types without the memory bloat of actually using objects to represent primitives. Autoboxing fakes it.
o Strings, numbers, arrays, hashes, and so on, each have their own API. Documentation for an exists method for arrays doesn’t have to explain how hashes are handled and vice versa.
o Perl tries to accommodate the notion that the subject of a statement should be the first thing on the line, and autoboxing furthers this agenda.
Perl is an idiomatic language and this is an important idiom.

Subject First: An Aside

Perl’s design philosophy promotes the idea that the language should be flexible enough to allow programmers to place the subject of a statement first. For example, die $! unless read $file, 60 looks like the primary purpose of the statement is to die.

While that might be the programmers primary goal, when it isn’t, the programmer can communicate his real primary intention to programmers by reversing the order of clauses while keeping the exact same logic: read $file, 60 or die $!.

Autoboxing is another way of putting the subject first.

Nouns make good subjects, and in programming, variables, constants, and object names are the nouns. Function and method names are verbs. $noun->verb() focuses the readers attention on the thing being acted on rather than the action being performed. Compare to $verb($noun).

Autoboxing and Method Results

Let’s look at some examples of ways an expression could be written.

  # Various ways to do the same thing:

  print(reverse(sort(keys(%hash))));          # Perl 5 - pathological parenthetic
  print reverse sort keys %hash;              # Perl 5 - no unneeded parenthesis

  print(reverse(sort(%hash,keys))));          # Perl 6 - pathological
  print reverse sort %hash.keys;              # Perl 6 - no unneeded parenthesis

  %hash.keys ==> sort ==> reverse ==> print;  # Perl 6 - pipeline operator

  %hash.keys.sort.reverse.print;              # Perl 6 - autobox

  %hash->keys->sort->reverse->print;          # Perl 5 - autobox

This section deals with the last two of these equivalents. These are method calls

  use autobox::Core;
  use Perl6::Contexts;

  my %hash = (foo => bar, baz => quux);

  %hash->keys->sort->reverse->print;          # Perl 5 - autobox

  # prints "foo baz"

Each method call returns an array reference, in this example. Another method call is immediately performed on this value. This feeding of the next method call with the result of the previous call is the common mode of use of autoboxing. Providing no other arguments to the method calls, however, is not common.

Perl6::Contexts recognizes object context as provided by -> and coerces %hash and @array into references, suitable for use with autobox. (Note that autobox also does this automatically as of version 2.40.)

autobox associates primitive types, such as references of various sorts, with classes. autobox::Core throws into those classes methods wrapping Perl’s built-in functions. In the interest of full disclosure, Perl6::Contexts and autobox::Core are my creations.

Autobox to Simplify Expressions

One of my pet peeves in programming is parenthesis that span large expression. It seems like about the time I’m getting ready to close the parenthesis I opened on the other side of the line, I realize that I’ve forgotten something, and I have to arrow back over or grab the mouse.

When the expression is too long to fit on a single line, it gets broken up, then I must decide how to indent it if it grows to 3 or more lines.

  # Perl 5 - a somewhat complex expression

  print join("\n", map { CGI::param($_) } @cgi_vars), "\n";
  # Perl 5 - again, using autobox:

  @cgi_vars->map(sub { CGI::param($_[0]) })->join("\n")->concat("\n")->print;

The autoboxed version isn’t shorter, but it reads from left to right, and the parenthesis from the join() don’t span nearly as many characters. The complex expression serving as the value being join()ed in the non-autoboxed version becomes, in the autoboxed version, a value to call the join() method on.

This print statement takes a list of CGI parameter names, reads the values for each parameter, joins them together with newlines, and prints them with a newline after the last one.

Pretending that this expression were much larger and it had to be broken to span several lines, or pretending that comments are to be placed after each part of the expression, you might reformat it as such:

  @cgi_vars->map(sub { CGI::param($_[0]) })  # turn CGI arg names into values
           ->join("\n")                      # join with newlines
           ->concat("\n")                    # give it a trailing newline
           ->print;                          # print them all out

Here ends the text quoted from the Perl 6 Now manuscript.

The API is not yet stable — Perl 6-ish things and local extensions are still being renamed.
