NAME

lib::coreplus - Allow core modules plus a few others

VERSION

This document describes version 0.281 of lib::coreplus (from Perl distribution lib-filter), released on 2021-08-29.

SYNOPSIS

 % perl -Mlib::coreplus=Clone,Data::Structure::Util yourscript.pl

DESCRIPTION

This pragma uses lib::filter's custom "filter" to accomplish its function.

Rationale for this pragma: using "lib::filter"'s "allow_noncore=0"+"allow" doesn't work for non-core XS modules because "allow_noncore=0" will remove non-core directories from @INC, while XS modules will still look for their loadable objects in @INC during loading.

So the alternative approach used by "lib::coreplus" is to check the module against "Module::CoreList->is_core". If the module is not a core module according to "is_core", it is then checked against the list of additional modules specified by the user. If both checks fail, the module is disallowed. lib::coreplus does not remove directories from @INC because it does not use "allow_noncore=0".

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, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
