NAME Require::Hook - Namespace for require() hooks VERSION This document describes version 0.004 of Require::Hook (from Perl distribution Require-Hook), released on 2023-12-05. DESCRIPTION NOTE: Please see Require::HookPlugin instead which largely supersedes this. As one already understands, Perl lets you put coderefs or objects in @INC as "hooks". This lets you do all sorts of things when it comes to loading modules, for example: * faking that a module does not exist when it does This can be used for testing. * loading module from various sources You can load module source from the DATA section or variables, as is done in a fatpacked script. Or you can retrieve module source from CPAN so a script can magically run without installing extra CPAN modules. * munging source code Like adding some Perl code before ("use strict;") or after, for testing purpose or otherwise. * decrypt from an ecrypted source In the case of objects, perl will call your "INC" method. So this is how you would write a module for a require hook: package My::INCHandler; sub new { ... } sub My::INCHandler::INC { my ($self, $filename) = @_; ... } 1; "Require::Hook" is just a namespace to put and share all your require hooks. HOMEPAGE Please visit the project's homepage at <https://metacpan.org/release/Require-Hook>. SOURCE Source repository is at <https://github.com/perlancar/perl-Require-Hook>. SEE ALSO "Require::Hook::*" modules. Require::HookChain is a newer framework that largely supersedes Require::Hook. AUTHOR perlancar <perlancar@cpan.org> 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. COPYRIGHT AND LICENSE This software is copyright (c) 2023, 2020, 2017 by perlancar <perlancar@cpan.org>.
