Under maintenance.

Most probably CPANTS databases are being regenerated from scratch due to major changes in Kwalitee metrics or updates of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.

Kwalitee Issues


Change the permissions of Build.PL/Makefile.PL to not-executable.


Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.


Add a README to the distribution. It should contain a quick description of your module and how to install it.


Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.


  • MANIFEST (13) does not match dist (22):
  • Missing in MANIFEST: classdocs/Devel/RingBuffer.html, classdocs/Devel/RingBuffer.pod.html, classdocs/Devel/RingBuffer/Ring.html, classdocs/Devel/RingBuffer/Ring.pod.html, classdocs/index.html, classdocs/podstyle.css, classdocs/up.gif, lib/Devel/RingBuffer.pod, lib/Devel/RingBuffer/Ring.pod


List all used modules in META.yml requires


  • IPC::Mmap


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
