NAME
Acme::CPANModules::ModifiedHashes - List of modules that provide hashes with modified behaviors
VERSION
This document describes version 0.001 of Acme::CPANModules::ModifiedHashes (from Perl distribution Acme-CPANModules-ModifiedHashes), released on 2024-07-10.
DESCRIPTION
These modules allow you to create hashes that don't behave like a normal Perl hash.
Accessing hash values using approximate keys (fuzzy hash)
Allowing key aliases (multiple keys that refer to the same value)
Allowing multiple keys (list of keys)
Allowing references as keys
Case-insensitive hash keys
Encrypting values
Ordered
There are several modules that provide ordered hash, see separate list mentioned in SEE ALSO section.
Remembering keys only temporarily
Keywords: cache
Remembering only a certain number of keys
Keywords: cache
Restricted keys
Hashes that only allow certain keys and not others.
Using regular expressions as hash keys

BENCHMARK NOTES
Hash::Ordered has strong performance in iterating and returning keys, while List::Unique::DeterministicOrder is strong in insertion and deletion (or Tie::Hash::Indexed if you're looking for actual hash type).
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 ModifiedHashesAlternatively you can use the cpanmodules CLI (from App::cpanmodules distribution):
% cpanmodules ls-entries ModifiedHashes | cpanm -nor Acme::CM::Get:
% perl -MAcme::CM::Get=ModifiedHashes -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -nor directly:
% perl -MAcme::CPANModules::ModifiedHashes -E'say $_->{module} for @{ $Acme::CPANModules::ModifiedHashes::LIST->{entries} }' | cpanm -nThis 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 -lIf 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.
