This edition was made possible by the supporters of our cause.
Don't miss the next issue!

This week has seen a lot happening in the world of CPAN Testers. And I really mean a *lot*. The site has a new admin interface for testers and module authors, the find-a-tester service has been revamped and there are a slew of statistics being reported. On other fronts, we have a few looks back to YAPC::NA, some neat new web services for Perl developers, and the warning that changes are coming to a number of the core testing modules. Enjoy! ~ `/anick

Not only that but both Yanick and myself have prepared a full edition so now you get a double edition. I just hope I managed to remove the duplicate items :) ~ szabgab

Oh, and by the way, The Perl Weekly is looking for more sponsors. Especially companies that are looking for Perl developers.

Changes to Test::Builder/More/Simple incoming

by Chad Granum (EXODIST)

Changes are coming to the Test::* modules, Chad Granum warns us. As those modules are the foundation of most test suites, it might indeed be a good idea to check what those are.

YAPC::NA is on YouTube

by Ricardo Signes (RJBS)

Ricardo Signes went to YAPC::NA, and in this first installment of his impressions of the event, he lauds the way the conference presentations where uploaded to YouTube (to wit: all talks -- yes, all of them -- where streamed in pretty darn close to real-time, which is awesome).

My thoughts on this years YAPC::NA

Stevan Little had, alas, to sit this year's iteration of YAPC::NA as he was stuck in the middle of a move, but thanks to the real-time streaming of the talks and the magic of Twitter, he was very much with us, Obi-Wan-style.


How to Run a Single Test via Dist::Zilla

by Olaf Alders (OALDERS)

So you are using Dist::Zilla to manage your module and you want to run a single test out of its test suite? No problem at all, you can just run it directly. But if the module also has XS components, it's a little trickier. Fortunately, Olaf Alders found how to do it in a fairly simple way.

CPAN Submission Rates

Neil Bowers was wondering what was the frequency of cpantester reports coming in. Barbie created graphs to answer him, and the picture they draw is quite impressive. A graph showing the number of CPAN uploads by month, by week and by day. The week-ends are weaker and on the 31 of each month there is a huge drop in the number of uploads. Maybe because half the monthes don't have day 31...

New Distributions and Versions

by Barbie (BARBIE)

Statistics. Everybody love statistics. Here, Barbie compiled all the first versions of CPAN modules. Unsurprisingly, most modules begin their life with a variation on 1.0 / 0.1 / 0.001. But which one is the most popular? Take a guess, and go find out.

Find a Tester Revamped

by Barbie (BARBIE)

Barbie is tinkering with the cpantester infrastructure. More particularly, he's fine-tuning the reported emails for testers to be more flexible and accurate. Not a massive change, but undubiously a very useful one.

Writing deprecation notices in perl, optionally with Moose

by Caleb Cushing (XENO)

When legacy parts of your code are marked for an upcoming demise, there are several ways to make them issue deprecation notices. Caleb Cushing shows one way to do it using warnings's 'warnif' and (optionally) Moose's method modifiers.

Perl virtual tables for DBD::SQLite

by Laurent Dami (DAMI)

Dami wants to generate SQLite virtual tables from within Perl. From the comment section, it seems that he won't even have to roll up his sleeves: SQLite::VirtualTable might already provide all that he needs.


Samuel Kaufman draws our attention to a website (and the web app module that powers it) that provides a nice, web-based way to know which modules are bundled with the different versions of Perl itself.

Making git bisect more useful

by Curtis 'Ovid' Poe (OVID)

When hunting down the moment a bug has been introduced in a codebase, 'git bisect' is a blessing. Ovid reminds us here that the labeling of the different commits as 'good' or 'bad' can be automated, making the search for the commit where all went wrong all the faster.

Perl School Slides

by Dave Cross (DAVECROSS)

A few years ago, Dave Cross ran Perl training at the Google campus. He realized recently that he never shared publically the slide decks he had crafted for them. This terrible oversight is now rectified. Slides of his 'Database Programming with Perl and DBIx::Class' and 'Object-Oriented Programming with Perl and Moose' courses are now available to the general public.

Use of Dist::Zilla when adopting

by Neil Bowers (NEILB)

Dist::Zilla might be an overkill for small distribution, but using a standard approach by author makes a lot of sense. But how to switch from MakeMaker to Dist::Zilla?
