NAME Acme::CPANModules::RemovingElementsFromArray - List of modules to help remove elements from array VERSION This document describes version 0.002 of Acme::CPANModules::RemovingElementsFromArray (from Perl distribution Acme-CPANModules-RemovingElementsFromArray), released on 2023-09-30. DESCRIPTION Perl provides several ways to remove elements from an array. "shift" removes one element from the beginning, "pop" removes one element from the end, and "splice" removes a slice of array (and insert another list in its place). There's also "grep", which lets you filter a list with a user-supplied code. While this does not directly modify an array, you can simply assign the new filtered values to the array. And I might just as well mention array slice (@ary[1,3,4] or @ary[1..4]) which allows you to pick the range of elements you want by their indices. In addition to the above, there are also other modules which provide some convenience. Removing duplicate items List::Util provides "uniq" (as well as "uniqnum", "uniqint", "uniqstr") to remove duplicate items from a list. There's also List::Util::Uniq providing "dupe", "dupenum", "dupeint", and "dupestr", which return the duplicates instead. Removing overlapped items Array::OverlapFinder lets you find overlapping items from a series of arrays and optionally remove them. Variations of "grep" Some modules offer variations of "grep". For example, Array::KeepGrepped keeps the elements that are filtered out instead those that match the grep expression. List::Util::sglice offers "sglice", which removes elements that matches user-supplied code, except that "sglice" (like "splice") allows you to specify a limit to the number of elements to remove. mapslice List::Util::mapsplice offers "mapsplice", which removes a slice of array but lets you replace each element with new elements using Perl code.

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 RemovingElementsFromArray Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution): % cpanmodules ls-entries RemovingElementsFromArray | cpanm -n or Acme::CM::Get: % perl -MAcme::CM::Get=RemovingElementsFromArray -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n or directly: % perl -MAcme::CPANModules::RemovingElementsFromArray -E'say $_->{module} for @{ $Acme::CPANModules::RemovingElementsFromArray::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.

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, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2023 by perlancar <perlancar@cpan.org>.
