NAME
Acme::CPANModules::LoadingModules - List of modules to load other Perl
modules
VERSION
This document describes version 0.001 of
Acme::CPANModules::LoadingModules (from Perl distribution
Acme-CPANModules-LoadingModules), released on 2023-11-20.
DESCRIPTION
Basics
Module::Load is basically just a thin wrapper over Perl's builtin
require() to translate between module name and path name, since the
traditional behavior of require() is to expect module name in bareword
form but path name in string form. This confusion will likely be fixed
in future perl versions. For example, see PPC 0006 [1].

Installing modules automatically on demand
Since Perl provides require hooks, one can trap the module loading
process and check for an uninstalled module and attempt to install it
automatically on demand when a code wants to load that module. Probably
not suitable for use in production. See separate list:
Acme::CPANModule::ModuleAutoinstallers.
Loading module on demand
Aside from require hook, Perl also provides the AUTOLOAD mechanism (see
"perlsub" documentation for more details). This lets you catch unknown
function being called and lets you attempt to load a module that might
provide that function. It is not exactly "loading modules on demand" but
close enough for a lot of cases. See separate list:
Acme::CPANModule::ModuleAutoloaders.
Loading multiple modules at once
all requires all packages under a namespace. It will search the
filesystem for installed module source files under a specified namespace
and load them all.
lib::require::all loads all modules in a directory.
Logging module loading
Require::HookChain::log::logger
Require::HookChain::log::stderr
Preventing loading certain modules
lib::filter, lib::disallow
Require hook frameworks
These frameworks let you create require hook more easily.
Require::Hook
Require::Hook::More
Require::HookChain
Specifying relative paths
lib::relative

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 LoadingModules
Alternatively you can use the cpanmodules CLI (from App::cpanmodules
distribution):
% cpanmodules ls-entries LoadingModules | cpanm -n
or Acme::CM::Get:
% perl -MAcme::CM::Get=LoadingModules -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n
or directly:
% perl -MAcme::CPANModules::LoadingModules -E'say $_->{module} for @{ $Acme::CPANModules::LoadingModules::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.
