These "module autoinstallers" modules can automatically install missing module
during run-time using one of installers (usually `cpanm` a.k.a.
<pm:App::cpanminus>). Convenient when running a Perl script (that comes without
a proper distribution or `cpanfile`) that uses several modules which you might
not have. The alternative to lib::xi is the "trial and error" method: repeatedly
run the Perl script to see which module it tries and fails to load.

They work by installing a hook in `@INC`. Read more about require hooks in
`perlfunc` under the `require` function.

Acme::CPANModules::ModuleAutoinstallers - List of modules that autoinstalls other modules during run-time

=head1 VERSION

This document describes version 0.004 of Acme::CPANModules::ModuleAutoinstallers (from Perl distribution Acme-CPANModules-ModuleAutoinstallers), released on 2024-08-29.

=head1 DESCRIPTION

These "module autoinstallers" modules can automatically install missing module
during run-time using one of installers (usually C<cpanm> a.k.a.
L<App::cpanminus>). Convenient when running a Perl script (that comes without
a proper distribution or C<cpanfile>) that uses several modules which you might
not have. The alternative to lib::xi is the "trial and error" method: repeatedly
run the Perl script to see which module it tries and fails to load.

They work by installing a hook in C<@INC>. Read more about require hooks in
C<perlfunc> under the C<require> function.

=head1 FAQ

=head2 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 L<Acme::CPANModules> for more details.

=head2 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 L<cpanm-cpanmodules> script (from
L<App::cpanm::cpanmodules> distribution):

 % cpanm-cpanmodules -n ModuleAutoinstallers

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

    % cpanmodules ls-entries ModuleAutoinstallers | cpanm -n

or L<Acme::CM::Get>:

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