Require::Hook - Namespace for require() hooks
This document describes version 0.002 of Require::Hook (from Perl distribution Require-Hook), released on 2020-11-13.
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:
@INC
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.
use strict;
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:
INC
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.
