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.

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. HOMEPAGE Please visit the project's homepage at <https://metacpan.org/release/Acme-CPANModules-ModifiedHashes>.

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) 2024 by perlancar <perlancar@cpan.org>.
