Announcements

by Kaare Rasmussen (KAARE)
Djet is a Node Based Content Management System written in Perl. If you are confused like I was, don't worry. The 'node' in the name does not refer to Node.js, but more like the vertex in graph theory. I am not sure, but I think the code behind PerlMonks is also based on the same idea, of everything is a node.

Articles

The 'reverse' function of perl can easily trick people as it behaves differently in scalar and list context. In this article brian discusses some use cases when the scalar version of this function might be useful.

A modulino is a program that can act like a module, or a module that can be directly executed. While doing his CPAN Archeology brian turned his Makefile.PL into a modulino and shows how you could do that too.

Perl Maven Pro
The Perl Maven Pro subscribers receive two new articles and screencasts every week. The last week these were the two screencasts:
|
The beginning of a new series covering many advanced topics in Perl. This one starts the Object Oriented Programming with Moose section.
|
|
Using Moose to write classes in Perl is fun, but it is much more fun if we can even write unit-tests for our application.

Testing
|
by Dave Rolsky (DROLSKY)
Now with the CPAN Pull Request challenge going on, it is very interesting to read why a module author has delayed accepting a pull-request and how it lead to the creating of HTML::Differences that can find real differences between two HTML snippets.

|
by Chad Granum (EXODIST)
The Test-Simple distribution is the heart of all the testing in the Perl ecosystem. Changing it and releasing it to the CPAN can break the installation process of every Perl user around the worl. Helping Chad by testing it before he releases to everyone will surely make him happy.

Web
|
by Rob Lauer
Bedrock, or OpenBedrock is a web development framework that allows you to embed SQL code in HTML. To me it looks like something left here from the previous century, but I am impressed that Rob Lauer, the author keeps running the project and keeps writing blog-posts about it!

Dancer2 is faster than Dancer and some parts of it got even faster with this release.

CPAN
|
by Neil Bowers (NEILB)
Lots of people have signed up to the CPAN challenge Neil announced so he also needs the other part of the equation. Modules that need to be fixed.

|
by Neil Bowers (NEILB)
If you particiapate in the CPAN challenge of Neil, then you might wonder what kind of improvements could be considered in a module. Don't worry, Neil has already prepared a list of ideas and if you have others, you can comment on his blog.

Some ideas how to make sure the pull-request you send has a higher than average chance to get accepted.

|
|
by brian d foy (BDFOY)
As you upload newer and newer versions of your module to PAUSE and thus to CPAN, the old onese linger around taking up space and possibly confusing people. brian has this annual (or is that bi-annual?) ritual cleaning up his directory, removing the old versions. This time he goes further and makes sure modules he has on CPAN have their proper GitHub repository and other useful features.

Perl 6
|
by Gabor Szabo (SZABGAB)
I have been on-and-off Perl 6 for quite some time, so after the news about Larry Wall talking about Perl 6 being production ready in 2015 I started to wonder if I should start wrting about Perl 6 again. Judging by the comments on Reddit there are quite a few people who prefer to spew hatered than to be constructive. We'll see.

Travis-CI does not support Perl 6 yet, but with this binary version of Rakudo Star you can hook up your GitHub repository and get it smoke-tested by Travis-CI.
