While the '/x' modifier allows whitespace in most of a regex to improve readability,
the '/xx' modifier allows whitespace in bracketed character classes also.
This can be used to separate ranges and individual characters.
As a quickly contrived example to capture the first and last character of strings starting with alphanumerics and ending with certain punctuation characters:
We invite you to participate in The Perl Conference, which will take place in August 2017 in Amsterdam, The Netherlands. These meetings were formerly known as YAPC::EU, the yearly meeting of Perl Mongers in Europe.
The Perl conferences started off as grassroots user meetings, with discussions among Perl Mongers, and has grown from there. The focus is on enjoying the ideas of others, discovering new concepts, and feeling the enthusiasm of fellow programmers in the Perl (5) and Perl 6 programming languages.
This years' theme is: High-end Perl. We are open for contributions: sponsors and potential speakers, please continue reading this page.
The Perl Conference, 2017 will be held this year in Washington DC, at the US Patent and Trademark Office, from June 18 through June 23rd.
This is the conference that many of us have affectionately known as YAPC::NA::17.
If you haven't registered yet, please do so as soon as possible.
We want to make sure we're providing the best possible experience for our participants, and to that end, accurate registration counts are helpful, plus there is still time to get the early-bird rate.
We have talks scheduled from many of the best speakers known to the Perl community;
Damian Conway, Sawyer X, Randal Schwartz, Mark Jason Dominus, Ricardo Signes, and so many other strong speakers that I feel silly having mentioned the few that I did.
For those seeking additional enlightenment there are tutorials and master classes offered (by additional registration) on topics such as:
Perl in a Day (John Anderson)
Introduction to Moose (Dave Rolsky)
Perl Second Best Practices (Randal Schwartz)
Unicode and Associated Punishments (Ricardo Signes)
Early registration cost is $250, and late registration (Main event T-minus 14 days) will be $350, so there is still time to get your ticket, but you'll want to act sooner than later.
From the Perl Foundation Conferences Committee I would like to thank all of the organizers who have been working for many months on this, and who are currently neck deep in work tying up loose ends and caring for the many details.
It will be a great conference because of everyone in the Perl community who attends and participates, but it couldn't be a great conference without those organizers who
have devoted so much of their time and energy laying the foundation for the rest of us to build upon.
I am excited and can't wait to see everyone there.
(The German Perl workshop is an annual open-source-conference/workshop for everyone. It is being organised by the Perl programming language community. In 2017, it takes place at Bürgerhaus Wilhelmsburg, Mengestraße 20, 21107 Hamburg, Germany. Most talks are held in German language (but many presenters keep their slides in English for the international participants). Talks in English are very welcome, if submitted by non-German speakers.
This year's German Perl workshop is coming to Hamburg! As every workshops
relies on the speakers and talks, the website now will accept your
talk proposals for regular talks, lightning talks and/or tutorials
The German Perl workshop tries to offer a variety of talks and topics.
This means, while we generally prefer Perl talks over other topics, we still
consider and may accept non-Perl talks when they relate to a Perl programmer's
Please consider submitting a talk! (Best before 7 June.)
Otherwise, just participate, if you have no talk to submit.
The workshop takes place from 26 through 28 June 2017 at the
Bürgerhaus Wilhelmsburg in Hamburg, Germany
and we would like you to participate.

dieses Jahr findet der Deutsche Perl Workshop in Hamburg statt. Ein Workshop
ist nichts ohne Vortragende, daher ist die Webseite jetzt freigeschaltet für
das Einreiche von Vorträgen, Lightning Talks oder Tutorials.
Der Deutsche Perl Workshop versucht wie immer, ein breites Spektrum an Vorträgen
anzubieten und das bedeutet, dass wir zwar prinzipiell bevorzugen, wenn ein
Vortrag Perl berührt, aber es sind auch andere Themen möglich, solange es
hinreichend technisch ist.
Bitte überlege, ob Du einen Vortrag einreichen möchtest (idealerweise vor dem
7. Juni), oder nimm einfach so am Workshop Teil wenn Du keinen Vortrag
halten kannst. Der Workshop findet vom 26. Juni bis zum 28. Juni im
Bürgerhaus Wilhelmsburg in Hamburg statt und wir hoffen, dass Du teilnimmst.

A daemon that is properly started with no controlling terminal will never receive SIGHUP from the OS. Thus, it is convenient to repurpose SIGHUP to tell the daemon to read its configuration file. -- Steven W. McDougall
The Type::Tiny 1.1 (1.001_00x) development cycle has been going on since September 2014. Apparently I'm either very concerned about stability or very lazy. You can make up your own minds about that.
But Type::Tiny 1.2 should be released in a few weeks. If your application uses Type::Tiny, you may want to download the latest development release and check that nothing breaks. (It shouldn't, but you never know until you try.)
The headline changes are:
Type::Params now has compile_named and validate_named.
Type::Tiny's constraint parameter may be a string of code.
Fixed bug where Types::Standard::Int would sometimes accept an overloaded object. (It never should.)
Various performance enhancements and bug fixes.
I'll explain the first two in more detail, because they're interesting.
Type::Params is a module for type-checking the parameters to functions. For example, specifying that the $quantity parameter should be an integer. It was mostly written with positional parameters in mind, like eat_apples(2, "red").
Named parameters like eat_apples( quantity=>2, colour=>"red" ) could be made to work, but it was a bit of a hack. The Type::Tiny 1.1 development versions introduced a better way of doing this. It's not only neater, but it provides better error messages and it benchmarks a lot faster. Below is some code showing the old way and the new way.
Normally when creating a type constraint, you'd provide a coderef which checks the variable $_ to see if it should pass the constraint. Recently the development versions of Type::Tiny have started accepting a string of Perl code instead. This can not only lead to very concise code, but is an easy way to allow Type::Tiny to optimize its checks. (You can manually optimize them even better by telling Type::Tiny how to inline type checks, but that requires a little bit of extra effort.)
The German Perl Workshop is an Open Source conference for everyone, organized by community of the Perl Programming Language yearly in Germany. The 2017 GPW takes place in 21107 Hamburg, Mengestraße 20. The Venue is called Bürgerhaus Wilhelmsburg. Most of the talks will be held in German, but talks in English are welcome as well of course.
The workshop starts on June 25th with the preconference meeting.
For accompanying family members with we have organized a partner program on the 3 conference days.
The Perl Developer Survey ran from 7th of March to the 14th of April, 2017. I hope you took part! The results have now been published:
part 1part 2
I find the results intriguing, but since this was a self-selected (not random nor representative) sample, it's quite hard to generalise the results to the overall Perl developer population. Did you take part? Do you find yourself in the pie charts?
Along with the clone feature I added last cut that allows you to clone instances for specific projects/purposes, this new version provides a fetch command that automatically updates the Perls that are available, displaying the most recent point release available for each major version.
If any of your existing installed versions don't match what available lists, we'll automatically register those instances as custom, which allows them to continue to be maintained by berrybrew.
Here's the full blog post.
I applaud this decision by Github, as it allows expression to be expanded without fear. I do understand the concern that an employer could have (as I did run a few small businesses), but hacking out a few lines of code while at work during a break, for Open Source projects shouldn't be claimed as corporate IP.
This is a thing of opinion depending on the reader, but I digress. I am totally in favour.
This was posted at Perl is dead over on blogs.perl.org with that title (here's the actual follow-through link to the real article). The title is over the top, but this topic has been brought up here recently, so I thought I'd put it here for our mathematicians/statisticians and other interested Monks.
Personally, I don't care. I love Perl, and likely always will. I have learned other languages while knowing Perl, but as I learn other languages, I just learn new ways to incorporate what I know into Perl. Learning new things and incorporating them into experience I've gained is how I approach everything anyways.
