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.

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 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.

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,
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.
