CPAN News

http://shadow.cat/blog/matt-s-trout/moo-2-strictures-2/
Version 2 of Moo ("https://metacpan.org/pod/Moo") is now on CPAN. Matt

What's new on CPAN - February 2015
http://perltricks.com/article/156/2015/3/2/What-s-new-on-CPAN---February-2015
David's monthly update on new CPAN distributions released in the last
month. He now showcases a "module of the month" each time, and this month
that was File::Serialize ("https://metacpan.org/pod/File::Serialize"),
which is a nifty module, even if Yannick can't spell serialise.

("http://niceperl.blogspot.co.uk/2015/03/cl-metacpan-weekly-report-appgit

Tree::Renderer: A partial replacement for Data::TreeDumper
http://blogs.perl.org/users/ron_savage/2015/03/treerenderer-a-partial-replacement-for-datatreedumper.html
Ron is working on a module called Tree::Renderer
(not yet on
CPAN), for use instead of Data::TreeDumper
("https://metacpan.org/pod/Data::TreeDumper"), and he's open to feature
requests.

=============
PAUSE and CPAN
Distributions much have a main module with matching name
http://www.dagolden.com/index.php/2414/this-distribution-name-can-only-be-used-by-users-with-permission/
David describes a change in PAUSE that can result in a slightly perplexing
error message when you upload something to PAUSE. Basically, if you
upload a distribution Foo-Bar
to PAUSE, then it must contain
a module Foo::Bar
, otherwise it will not be added to the
CPAN index. Existing dists not meeting this rule got an exception, but
all new dists must satisfy this rule.

Mark outlines his plan for promoting companies that are using Perl in some
way.

http://blogs.perl.org/users/shadowcat_mdk/2015/03/the-company-culture-go-leader.html
Mark started his promotion of companies using Perl with a description of a
regional newspaper from New Jersey, USA. They've been using Perl for more
than 15 years, and recently contributed to the Perl 6 team's need for a
new server.
--------------
=============
Testing
Test-More status update
http://blogs.perl.org/users/chad_exodist_granum/2015/03/test-more-status-updae.html
An update from Chad on his work on the Test-More
("https://metacpan.org/release/Test-More" class="distribution")
distribution, in particular what exactly will be shipping with Perl 5.22.
He's been working on some refactoring, and benchmarking
("http://test-more.github.io/test-more/") his changes, but realised that
one of his changes didn't have the impact he'd thought. It's great to see
this getting discussed and written up "in the open".
--------------

Towards better Changes
https://perlancar.wordpress.com/2015/03/06/towards-better-changes-1/
Perlancar shares his thoughts on what should go in the Changes file for
your distributions. In particular, don't just say what you changed, but
why.
--------------
Fear and Loathing in SQL-92
https://blog.afoolishmanifesto.com/posts/fear-and-loathing-in-sql-92/
A war story used to illustrate a point, with some good tips and thoughts
thrown in. For example, do you use, or are you aware of the fc
("http://perldoc.perl.org/functions/fc.html") function (introduced in
5.16)? A good rule of thumb: "you should not emulate, imitate, or
otherwise do the job of the database".
--------------
Look At My Pretty Pictures
http://varlogrant.blogspot.co.uk/2015/03/look-at-my-pretty-pictures.html
Dave shows the code he wrote to write spirograph style pictures in SVG,
which he then etched onto wood using a laser cutter. I have no
justification for one, but a laser cutter is going on my wishlist!

http://yesistilluseperl.blogspot.co.uk/2015/03/book-review-perl-and-xml.html
A short review of the O'Reilly "Perl and XML" book, which was published in

he'd read it earlier.

=============
Perl 6
Perl 6 for Mere Mortals - FOSDEM Video
http://blogs.perl.org/users/ovid/2015/03/perl-6-for-mere-mortals---fosdem-video.html
The video from Curtis's talk at FOSDEM just over a month ago. Videos from
some of the Perl talks ("http://video.fosdem.org/2015/devroom-perl/") are
available, but not all of them have complete audio, alas.
--------------
Perl 6 weekly happenings
https://p6weekly.wordpress.com
You can now embed Perl 6 code in Java, native reference support has been
ported to the JVM, and you can now use keywords for sub, method, and
class names (it doesn't say why that might be a good idea).
--------------
=============
The PR Challenge
Various updates on the Pull Request Challenge
http://neilb.org/2015/03/09/prc-updates.html
A new home page for the challenge, changes in the way distributions are
scored, and a new hit list to help get dists onto github.
--------------
CPAN Pull Requests in February
http://neilb.org/2015/03/07/prc-feb-stats.html
A few charts showing how many pull requests were done for CPAN
distributions in February, and how that compares with previous years, and
with last month. TL;DR: much better, not quite as good, respectively.
--------------
CPAN PR-Challenge: March Report #2
http://blogs.perl.org/users/alberto_simoes/2015/03/cpan-pr-challenge-march-report-2.html
Alberto describes his work for a PR on Exobrain
("https://metacpan.org/pod/Exobrain"). I've added one idea to our central
ideas list
("https://github.com/CPAN-PRC/resources/wiki/Pull-Request-Ideas"): check
whether any of the dependencies should have a minimum version specified.
I was bitten by this issue just this week — easy to do if you
regularly upgrade your Perl and re-install CPAN.
