If you have two arrays and you want to know if they are the same or different, then Array::Compare will be useful to you. All comparisons are carried out via a comparator object. In the simplest usage, you can create and use a comparator object like ...

This module implements a priority queue, which is a data structure that can efficiently locate the item with the lowest weight at any time. This is useful for writing cost-minimizing and shortest-path algorithms. When creating a new queue, you supply...

This module helps to solve easy tasks with arrays. Comparing of arrays or filtering array data are this kind of task that this module supports. Functions The following parameter names ARRAY, ARRAY1 and ARRAY2 are synonyms for array any kind of arrays...

There are a multitude of heap and heap-like modules on CPAN, you might want to search for /Heap/ and /Priority/ to find many. They implement more or less fancy datastructures that might well be what you are looking for. This module takes a different ...

This module compares two pre-sorted arrays and returns the added or deleted elements in two separate arrays. It's a simple wrapper around Algorithm::Diff. Note: the arrays must be sorted before you call "diff". And if you need more complex array tool...

This module provides one subroutine: "find_in_array" to find items in array....

Ein Objekt der Klasse repräsentiert ein Array. Jede der Methoden kann sowohl auf ein Objekt der Klasse als auch als Klassenmethode auf ein ungeblesstes oder eine andere Klasse geblesstes Perl-Array angewendet werden. Aufruf als Objektmethode: $arr->$...

YAML::PP is a modular YAML processor. It aims to support "YAML 1.2" and "YAML 1.1". See <https://yaml.org/>. Some (rare) syntax elements are not yet supported and documented below. YAML is a serialization language. The YAML input is called "YAML Stre...

Data::Match provides extensible complex Perl data structure searching and matching....

This package lets you create an array which will allow only one occurrence of any value. In other words no matter how many times you put in 42 it will keep only the first occurrence and the rest will be dropped. You use the module via tie and once yo...

Perl's "chdir()" has the unfortunate problem of being very, very, very global. If any part of your program calls "chdir()" or if any library you use calls "chdir()", it changes the current working directory for the *whole* program. This sucks. File::...

igroup_by "igroup_by()" returns an iterator which when called, returns sub-arrays of the given array whose elements are "equal" as determined by a user-supplied boolean function. The iterator does this by stepping through the given data array, compar...

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...

"Array::IntSpan" brings the speed advantages of "Set::IntSpan" (written by Steven McDougall) to arrays. Uses include manipulating grades, routing tables, or any other situation where you have mutually exclusive ranges of integers that map to given va...

As shown in the above examples, the general usage is: package MyClass; use Moose; (define Moose object(s)) ... use Array::To::Moose; ... my $data_ref = selectall_arrayref($sql); # for example my $object_ref = array_to_moose( data => $data_ref desc =>...

This presents an ordinary array, but is kept sorted. All pushes and unshifts cause the elements in question to be inserted in the appropriate location to maintain order. Direct stores ("$a[10] = "wibble"") effectively splice out the original value an...

Array::PatternMatcher is based directly on the pattern matcher in Peter Norvig's excellent text "Paradigms of AI Programming: Case Studies in Common Lisp". All in all, it basically offers a different way to work with an array. Instead of manually ind...
