This is free software; you can redistribute it and/or modify it under
the same terms as the Perl 5 programming language system itself.
Terms of the Perl programming language system itself

Software Foundation; either version 1, or (at your option) any
later version, or
b) the "Artistic License"
--- The GNU General Public License, Version 1, February 1989 ---
This software is Copyright (c) 2021, 2016, 2015 by perlancar <perlancar@cpan.org>.
This is free software, licensed under:
The GNU General Public License, Version 1, February 1989
GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of a such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must tell them their rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work based
on the Program" means either the Program or any work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
1. You may copy and distribute verbatim copies of the Program's source
code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that refer to this
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this General
Public License.
d) You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection in
exchange for a fee.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 1 and 2 above provided that you also do one of the following:
a) accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying the Program (or any work based
on the Program) you indicate your acceptance of this license to do so,
and all its terms and conditions.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these
terms and conditions. You may not impose any further restrictions on the
recipients' exercise of the rights granted herein.
7. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of the license which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
the license, you may choose any version ever published by the Free Software
Foundation.
8. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 1, or (at your option)
any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.

The Artistic License 1.0
The Artistic License
Preamble
The intent of this document is to state the conditions under which a Package
may be copied, such that the Copyright Holder maintains some semblance of
artistic control over the development of the package, while giving the users of
the package the right to use and distribute the Package in a more-or-less
customary fashion, plus the right to make reasonable modifications.
Definitions:
- "Package" refers to the collection of files distributed by the Copyright
Holder, and derivatives of that collection of files created through
textual modification.
- "Standard Version" refers to such a Package if it has not been modified,
or has been modified in accordance with the wishes of the Copyright
Holder.
- "Copyright Holder" is whoever is named in the copyright or copyrights for
the package.
- "You" is you, if you're thinking about copying or distributing this Package.
- "Reasonable copying fee" is whatever you can justify on the basis of media
cost, duplication charges, time of people involved, and so on. (You will
not be required to justify it to the Copyright Holder, but only to the
computing community at large as a market that must bear the fee.)
- "Freely Available" means that no fee is charged for the item itself, though
there may be fees involved in handling the item. It also means that
recipients of the item may redistribute it under the same conditions they
received it.
1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.
2. You may apply bug fixes, portability fixes and other modifications derived
from the Public Domain or from the Copyright Holder. A Package modified in such
a way shall still be considered the Standard Version.
3. You may otherwise modify your copy of this Package in any way, provided that
you insert a prominent notice in each changed file stating how and when you
changed that file, and provided that you do at least ONE of the following:
a) place your modifications in the Public Domain or otherwise make them
Freely Available, such as by posting said modifications to Usenet or an
equivalent medium, or placing the modifications on a major archive site
such as ftp.uu.net, or by allowing the Copyright Holder to include your
modifications in the Standard Version of the Package.
b) use the modified Package only within your corporation or organization.
c) rename any non-standard executables so the names do not conflict with
standard executables, which must also be provided, and provide a separate
manual page for each non-standard executable that clearly documents how it
differs from the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
4. You may distribute the programs of this Package in object code or executable
form, provided that you do at least ONE of the following:
a) distribute a Standard Version of the executables and library files,
together with instructions (in the manual page or equivalent) on where to
get the Standard Version.
b) accompany the distribution with the machine-readable source of the Package
with your modifications.
c) accompany any non-standard executables with their corresponding Standard
Version executables, giving the non-standard executables non-standard
names, and clearly documenting the differences in manual pages (or
equivalent), together with instructions on where to get the Standard
Version.
d) make other distribution arrangements with the Copyright Holder.
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this Package. You
may not charge a fee for this Package itself. However, you may distribute this
Package in aggregate with other (possibly commercial) programs as part of a
larger (possibly commercial) software distribution provided that you do not
advertise this Package as a product of your own.
6. The scripts and library files supplied as input to or produced as output
from the programs of this Package do not automatically fall under the copyright
of this Package, but belong to whomever generated them, and may be sold
commercially, and may be aggregated with this Package.
7. C or perl subroutines supplied by you and linked into this Package shall not
be considered part of this Package.
8. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.
9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

NAME
lib::filter - Allow/disallow loading modules
VERSION
This document describes version 0.281 of lib::filter (from Perl
distribution lib-filter), released on 2021-08-29.
SYNOPSIS
use lib::filter %opts;
DESCRIPTION
lib::filter lets you allow/disallow loading modules using some rules. It
works by installing a coderef in @INC (and additionally by pruning some
entries in @INC). The main use-case for this pragma is for testing.
It has been pointed out to me that for some tasks, alternatives to using
this module exist, so I'll be presenting those in the examples below.
* To disallow loading any module:
% perl -Mlib::filter=allow_core,0,allow_noncore,0 yourscript.pl
You can also use lib::none for this, or simply empty @INC yourself,
e.g.:
{
local @INC = ();
...
}
To no-op instead of disallowing, see lib::noop::all.
* To allow only core modules:
For example for testing a fatpacked script (see App::FatPacker):
% perl -Mlib::filter=allow_noncore,0 yourscript.pl
You can also use lib::core::only for this, which comes with the
App::FatPacker distribution.
* To only allow a specific set of modules:
% perl -Mlib::filter=allow_core,0,allow_noncore,0,allow,'XSLoader;List::Util' yourscript.pl
To no-op instead of disallowing, see lib::noop::except.
* To allow core modules plus some additional modules:
For example to test a fatpacked script that might still require some
XS modules:
# allow additional modules by pattern
% perl -Mlib::filter=allow_noncore,0,allow_re,'^DateTime::.*' yourscript.pl
# allow additional modules listed in a file
% perl -Mlib::filter=allow_noncore,0,allow_list,'/tmp/allow.txt' yourscript.pl
# allow core modules plus additional modules found in some dirs
% perl -Mlib::filter=allow_noncore,0,extra_inc,'.:proj/lib' yourscript.pl
# allow some non-core XS modules
% perl -MModule::CoreList -Mlib::filter=filter,'sub{ return 1 if Module::CoreList->is_core($_); return 1 if m!Clone|Acme/Damn!; 0' yourscript.pl
% perl -Mlib::coreplus=Clone,Acme::Damn yourscript.pl
Alternatively, you can also test by preloading the additional
modules before using lib::core::only:
% perl -mClone -mAcme::Damn -Mlib::core::only yourscript.pl
* To allow a module and recursively all other modules that the module
requires
This is convenient when we want to allow a non-trivial module which
itself uses some other modules, e.g. Moo or Moose:
% perl -Mlib::filter=allow_noncore,0,allow,Moo,allow_is_recursive=0
* To disallow some modules:
For example to test that a script can still run without a module
(e.g. an optional prereq):
% perl -Mlib::filter=disallow,'YAML::XS;JSON::XS' yourscript.pl
# idem, but the list of disallowed modules are retrieved from a file
% perl -Mlib::filter=disallow_list,/tmp/disallow.txt yourscript.pl
Devel::Hide is another module which you can you for exactly this
purpose:
% perl -MDevel::Hide=YAML::XS,JSON::XS yourscript.pl
To no-op instead of disallowing, see lib::noop.
* Do custom filtering
% perl -Mlib::filter=filter,sub{not/^Foo::/} yourscript.pl
OPTIONS
Known options:
* debug => bool
If set to true, print diagnostics when filtering.
* disallow => str
Add a semicolon-separated list of modules to disallow.
* disallow_re => str
Add modules matching regex pattern to disallow.
* disallow_list => filename
Read a file containing list of modules to disallow (one module per
line).
* allow => str
Add a semicolon-separated list of module names to allow.
* allow_re => str
Allow modules matching regex pattern.
* allow_list => filename
Read a file containing list of modules to allow (one module per
line).
* allow_is_recursive => bool (default: 0)
If set to 1, then will also allow modules that are required by the
allowed modules (and modules that are allowed by *those* modules,
and so on). This is convenient if you want to allow a non-trivial
module, say, Moo or Moose which will require other modules too.
Without this option, you will need to explicitly allow each of those
modules yourself.
* allow_core => bool (default: 1)
Allow core modules.
* allow_noncore => bool (default: 1)
Allow non-core modules.
* extra_inc => str
Add additional path to search modules in. String must be
colon-separated paths.
* filter => code
Do custom filtering. Code will receive module name (e.g.
"Foo/Bar.pm") as its argument ($_ is also localized to contained the
module name, for convenience) and should return 1 if the module
should be allowed.
How a module is filtered:
* First it's checked against "filter", if that option is defined
* then, it is checked against the
"disallow"/"disallow_re"/"disallow_list".
If it matches one of those options then the module is disallowed.
* Otherwise it is checked against the "allow"/"allow_re"/"allow_list".
If it matches one of those options and the module's path is found in
the directories in @INC, then the module is allowed.
* If "allow_is_recursive" is true, check the requirer.
If the calling package is already in %INC, we allow that. For
example, if we allow "Moo" and "Moo" calls Moo::_strictures and
Module::Runtime, we will also allow them. Later if
"Moo::_strictures" tries to load strictures, we also allow it, and
so on.
* Finally, allow_core/allow_noncore is checked.
When "allow_core" is set to false, core directories are excluded.
Likewise, when "allow_noncore" is set to false, non-core directories
are excluded.
ENVIRONMENT
PERL_LIB_FILTER_DEBUG
Boolean. Sets the default for the "debug" option.

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.

lib::coreplus - Allow core modules plus a few others
=head1 VERSION
This document describes version 0.281 of lib::coreplus (from Perl distribution lib-filter), released on 2021-08-29.
=head1 SYNOPSIS
% perl -Mlib::coreplus=Clone,Data::Structure::Util yourscript.pl
=head1 DESCRIPTION
This pragma uses L<lib::filter>'s custom C<filter> to accomplish its function.
Rationale for this pragma: using C<lib::filter>'s C<allow_noncore=0>+C<allow>
doesn't work for non-core XS modules because C<allow_noncore=0> will remove
non-core directories from C<@INC>, while XS modules will still look for their
loadable objects in C<@INC> during loading.
So the alternative approach used by C<lib::coreplus> is to check the module
against C<< Module::CoreList->is_core >>. If the module is not a core module
according to C<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 C<@INC> because it does not use
C<allow_noncore=0>.

=head1 NAME
lib::filter - Allow/disallow loading modules
=head1 VERSION
This document describes version 0.281 of lib::filter (from Perl distribution lib-filter), released on 2021-08-29.
=head1 SYNOPSIS
use lib::filter %opts;
=head1 DESCRIPTION
lib::filter lets you allow/disallow loading modules using some rules. It works
by installing a coderef in C<@INC> (and additionally by pruning some entries in
C<@INC>). The main use-case for this pragma is for testing.
It has been pointed out to me that for some tasks, alternatives to using this
module exist, so I'll be presenting those in the examples below.
=over
=item * To disallow loading any module:
% perl -Mlib::filter=allow_core,0,allow_noncore,0 yourscript.pl
You can also use L<lib::none> for this, or simply empty C<@INC> yourself, e.g.:
{
local @INC = ();
...
}
To no-op instead of disallowing, see L<lib::noop::all>.
=item * To allow only core modules:
For example for testing a fatpacked script (see L<App::FatPacker>):
% perl -Mlib::filter=allow_noncore,0 yourscript.pl
You can also use L<lib::core::only> for this, which comes with the
L<App::FatPacker> distribution.
=item * To only allow a specific set of modules:
% perl -Mlib::filter=allow_core,0,allow_noncore,0,allow,'XSLoader;List::Util' yourscript.pl
To no-op instead of disallowing, see L<lib::noop::except>.
=item * To allow core modules plus some additional modules:
For example to test a fatpacked script that might still require some XS modules:
# allow additional modules by pattern
% perl -Mlib::filter=allow_noncore,0,allow_re,'^DateTime::.*' yourscript.pl
# allow additional modules listed in a file
% perl -Mlib::filter=allow_noncore,0,allow_list,'/tmp/allow.txt' yourscript.pl
# allow core modules plus additional modules found in some dirs
% perl -Mlib::filter=allow_noncore,0,extra_inc,'.:proj/lib' yourscript.pl
# allow some non-core XS modules
% perl -MModule::CoreList -Mlib::filter=filter,'sub{ return 1 if Module::CoreList->is_core($_); return 1 if m!Clone|Acme/Damn!; 0' yourscript.pl
% perl -Mlib::coreplus=Clone,Acme::Damn yourscript.pl
Alternatively, you can also test by preloading the additional modules before
using lib::core::only:
% perl -mClone -mAcme::Damn -Mlib::core::only yourscript.pl
=item * To allow a module and recursively all other modules that the module requires
This is convenient when we want to allow a non-trivial module which itself uses
some other modules, e.g. L<Moo> or L<Moose>:
% perl -Mlib::filter=allow_noncore,0,allow,Moo,allow_is_recursive=0
=item * To disallow some modules:
For example to test that a script can still run without a module (e.g. an
optional prereq):
% perl -Mlib::filter=disallow,'YAML::XS;JSON::XS' yourscript.pl
# idem, but the list of disallowed modules are retrieved from a file
% perl -Mlib::filter=disallow_list,/tmp/disallow.txt yourscript.pl
L<Devel::Hide> is another module which you can you for exactly this purpose:
% perl -MDevel::Hide=YAML::XS,JSON::XS yourscript.pl
To no-op instead of disallowing, see L<lib::noop>.
=item * Do custom filtering
% perl -Mlib::filter=filter,sub{not/^Foo::/} yourscript.pl
=back
=for Pod::Coverage .+
=head1 OPTIONS
Known options:
=over
=item * debug => bool
If set to true, print diagnostics when filtering.
=item * disallow => str
Add a semicolon-separated list of modules to disallow.
=item * disallow_re => str
Add modules matching regex pattern to disallow.
=item * disallow_list => filename
Read a file containing list of modules to disallow (one module per line).
=item * allow => str
Add a semicolon-separated list of module names to allow.
=item * allow_re => str
Allow modules matching regex pattern.
=item * allow_list => filename
Read a file containing list of modules to allow (one module per line).
=item * allow_is_recursive => bool (default: 0)
If set to 1, then will also allow modules that are required by the allowed
modules (and modules that are allowed by I<those> modules, and so on). This is
convenient if you want to allow a non-trivial module, say, L<Moo> or L<Moose>
which will require other modules too. Without this option, you will need to
explicitly allow each of those modules yourself.
=item * allow_core => bool (default: 1)
Allow core modules.
=item * allow_noncore => bool (default: 1)
Allow non-core modules.
=item * extra_inc => str
Add additional path to search modules in. String must be colon-separated paths.
=item * filter => code
Do custom filtering. Code will receive module name (e.g. C<Foo/Bar.pm>) as its
argument (C<$_> is also localized to contained the module name, for convenience)
and should return 1 if the module should be allowed.
=back
How a module is filtered:
=over
=item * First it's checked against C<filter>, if that option is defined
=item * then, it is checked against the C<disallow>/C<disallow_re>/C<disallow_list>.
If it matches one of those options then the module is disallowed.
=item * Otherwise it is checked against the C<allow>/C<allow_re>/C<allow_list>.
If it matches one of those options and the module's path is found in the
directories in C<@INC>, then the module is allowed.
=item * If C<allow_is_recursive> is true, check the requirer.
If the calling package is already in C<%INC>, we allow that. For example, if we
allow C<Moo> and C<Moo> calls L<Moo::_strictures> and L<Module::Runtime>, we
will also allow them. Later if C<Moo::_strictures> tries to load L<strictures>,
we also allow it, and so on.
=item * Finally, allow_core/allow_noncore is checked.
When C<allow_core> is set to false, core directories are excluded. Likewise,
when C<allow_noncore> is set to false, non-core directories are excluded.
=back
=head1 ENVIRONMENT
=head2 PERL_LIB_FILTER_DEBUG
Boolean. Sets the default for the C<debug> option.

=head1 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 L<Dist::Zilla>,
L<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.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=lib-filter>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
