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

    Tie::RegexpHash

    Tie::Hash::Regex

    Tie::Hash::RegexKeys

    Others

    Tie::Hash::NoOp

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.
