NAME

Acme::CPANModules::DataStructureWalker - List of modules that traverse your data structure

VERSION

This document describes version 0.003 of Acme::CPANModules::DataStructureWalker (from Perl distribution Acme-CPANModules-DataStructureWalker), released on 2023-10-29.

DESCRIPTION

This list catalogs modules that let you traverse your data structure by visiting each node/item: each element of an array, each key/value pair of a hash, recursively. Sort of like File::Find for your data instead of filesystem. These modules can be used for searching or modifying your data.

Many modules in this list mimic Perl's map interface, for example: Data::Rmap, Data::Dmap, Data::Traverse. The difference among these modules lies in the details: in how you specify option to skip unsupported types of references, or whether some let you control the recursion (e.g. Data::Rmap's and Data::Dmap's cut),

Data::Walk models its interface on File::Find. It lets you choose whether you want to go depth-first or breadth-first.

Benchmarks for these modules coming soon.

Related modules:

Data::Clean can be used to clean/sanitize your data structure more performantly compared to your manual walking (e.g. using Data::Rmap). It works by generating Perl code specifically for your cleaning needs.

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 DataStructureWalker

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

% cpanmodules ls-entries DataStructureWalker | cpanm -n

or Acme::CM::Get:

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

or directly:

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