NAME

Acme::CPANModules::Set - List of modules that deal with sets

VERSION

This document describes version 0.001 of Acme::CPANModules::Set (from Perl distribution Acme-CPANModules-Set), released on 2022-03-18.

DESCRIPTION

Set is an abstract data type that can store unique values, without any particular order.

In Perl, you can implement set with a hash, with O(1) for average search speed. The downside is hash keys are limited to strings, but you can store complex data structures as values with some simple workaround. Less preferrably, you can also use an array to implement a hash, with O(n) for all insertion/deletion/search speed as you need to compare all array elements first for (uniqueness of) values. Finally, you can choose from various existing CPAN modules that handle sets.

ACME::CPANMODULES ENTRIES

  • Set::Light - (memory efficient) unordered set of strings

    Author: RRWO

    Basically just a hash underneath. You are limited to storing strings as values. Does not provide interset operations.

  • Set::Tiny - Simple sets of strings

    Author: TRENDELS

    Uses hash underneath, so you are also limited to storing strings as values. but unlike Set::Light, provides more methods.

  • Array::Set - Perform set operations on arrays

    Author: PERLANCAR

    Performs set operations on array

FAQ

What is an Acme::CPANModules::* module?

An Acme::CPANModules::* module, like this module, contains just a list of module names that share a common characteristics. It is a way to categorize modules and document CPAN. See Acme::CPANModules for more details.

What are ways to use this Acme::CPANModules module?

Aside from reading this Acme::CPANModules module's POD documentation, you can install all the listed modules (entries) using cpanm-cpanmodules script (from App::cpanm::cpanmodules distribution):

% cpanm-cpanmodules -n Set

Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution):

% cpanmodules ls-entries Set | cpanm -n

or Acme::CM::Get:

% perl -MAcme::CM::Get=Set -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

or directly:

% perl -MAcme::CPANModules::Set -E'say $_->{module} for @{ $Acme::CPANModules::Set::LIST->{entries} }' | cpanm -n

This Acme::CPANModules module also helps lcpan produce a more meaningful result for lcpan related-mods command when it comes to finding related modules for the modules listed in this Acme::CPANModules module. See App::lcpan::Cmd::related_mods for more details on how "related modules" are found.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
