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)

Tie::Hash::Approx

Allowing key aliases (multiple keys that refer to the same value)

Tie::Alias::Hash

Tie::Hash::Abbrev

Allowing multiple keys (list of keys)

Tie::Hash::MultiKey

Allowing references as keys

Hash::ExtendedKeys

Case-insensitive hash keys

Tie::CPHash

Encrypting values

Tie::EncryptedHash

Ordered

There are several modules that provide ordered hash, see separate list mentioned in SEE ALSO section.

Remembering keys only temporarily

Keywords: cache

Tie::Hash::Expire

Remembering only a certain number of keys

Keywords: cache

Tie::CacheHash

Tie::Cache

Tie::Cache::LRU

Restricted keys

Hashes that only allow certain keys and not others.

Hash::RestrictedKeys

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 ModifiedHashes

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

% cpanmodules ls-entries ModifiedHashes | cpanm -n

or Acme::CM::Get:

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

or directly:

% perl -MAcme::CPANModules::ModifiedHashes -E'say $_->{module} for @{ $Acme::CPANModules::ModifiedHashes::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.
