berrybrew, the Perlbrew for Windows v1.13 released

    I've released berrybrew version 1.13.

    The most notable change is the addition of the register command, which allows you to copy/move existing Strawberry Perl portable editions from your local/remote systems and have them operate as custom instances within berrybrew. Before registering a new instance:

    > berrybrew available The following Strawberry Perls are available: 5.26.0_64 5.26.0_64_PDL 5.26.0_32 5.24.1_64 [installed] * 5.24.1_64_PDL 5.24.1_32 5.22.3_64 5.22.3_64_PDL 5.22.3_32 5.20.3_64 5.20.3_64_PDL 5.20.3_32 5.18.4_64 5.18.4_32 5.16.3_64 5.16.3_32 5.14.4_64 5.14.4_32 5.12.3_32 5.10.1_32 5.8.9_32 * Currently using

    Now, copy your new instance into the instance directory (by default c:/berrybrew), then register it. I've used new_instance as the example instance directory in this case:

    > berrybrew register new_instance > berrybrew available The following Strawberry Perls are available: 5.26.0_64 5.26.0_64_PDL 5.26.0_32 5.24.1_64 [installed] * 5.24.1_64_PDL 5.24.1_32 5.22.3_64 5.22.3_64_PDL 5.22.3_32 5.20.3_64 5.20.3_64_PDL 5.20.3_32 5.18.4_64 5.18.4_32 5.16.3_64 5.16.3_32 5.14.4_64 5.14.4_32 5.12.3_32 5.10.1_32 5.8.9_32 new_instance [custom] [installed] * Currently using

    That instance can now be used under berrybrew.

    Other notable changes:

    • pryrt sent in a very large pull request that did a sweeping overhaul on the unit test framework which makes it much more flexible and reliable (thanks!)
    • added new exception handling for certain edge cases
    • documentation updates
    • closing of several minor issues

    Here's the full list of available commands:

    > berrybrew berrybrew <command> [subcommand] [option] available List available Strawberry Perl versions and which are +installed clean * Remove all temporary berrybrew files clone Make a complete copy of a Perl installation config Add berrybrew to your PATH exec * Run a command for every installed Strawberry Perl fetch Update the list of Strawberry Perl instances available install Download, extract and install a Strawberry Perl off Disable berrybrew perls (use 'switch' to re-enable) register Manually register a custom installation directory remove Uninstall a Strawberry Perl switch Switch to use a different Strawberry Perl unconfig Remove berrybrew from PATH upgrade Performs a safe upgrade.

    Hi!

    It's https://metacpan.org/release/Outthentic.

    Now:

    1. Check files are now optional. Priorly to this version one would have had to create empty chef files in case they didn't need script's checking which was quite awkward :)).
    2. The documentation has been improved. Hopefully it has become more clear and to the point.
    3. Meta stories have been demolished and meta.txt files "became" just a stories' headers.

    -- Regards

    Alexey

Because CPAN Needs More Templating Modules

    Why learn a whole new language for templating when you already know a perfectly good one? This isn't the first module that allows you to embed Perl in your templates, but it's yet another one.

    use Types::Standard -types; use Template::Compiled; my $template = Template::Compiled->new( signature => [ name => Str, age => Int->plus_coercions(Num, sub { int $_ } ), ], template => '<p>Hi <?= $name ?>. You are <?= $age ?> years old.</p +>', escape => 'html', ); # The number will be rounded. # The ampersand will be escaped properly. # print $template->( name => 'Alice & Bob', age => 45.1 );

    Arrival Dinner - Sunday June 18

    Arrangements have been made with Zikrayet Restaurant and Lounge to host a large crowd for The Perl Conference Arrival Dinner.

    Given the nature of the place, it will be possible to make this event more of a come and hang out destination than we've been able to have in past years. Just the same we have an official time of 6pm set for the dinner so everyone can have a common plan for arrival.

    This is an arrivals dinner but not necessarily the arrivals dinner. It's also a tradition that others who prefer smaller crowds and/or a more vegan-friendly menu organize an Alt Arrival Dinner.

    For more information, or to note your intended attendance, please visit: https://github.com/dcbpw/tpc-2017-dc/wiki/Arrivals-Dinner#attendees

    For more information on the Alt Arrival Dinner: https://github.com/dcbpw/tpc-2017-dc/wiki/Alt-Arrival-Dinner

    Tuesday Night Social

    This year we are continuing the very successful event established in Orlando last year, instead of the big banquet of years before. We will still be having a social at 6 pm with appetizers and drinks. After a long day of following your favorite track come say hello to friends from far and near over a glass of wine or a pint of beer!

    Tutorials

    There’s still time to sign up! Some tutorials have very limited space, so sign up today! If you’ve already purchased your Conference pass, you can still add tutorials by logging in and making a separate purchase. The available tutorials are:

    • John Anderson - Perl in a Day - Sunday 6/18, $50
    • Dave Rolsky - Introduction to Moose - Sunday 6/18, $150
    • Randal Schwartz - Perl Second Best Practices - Sunday 6/18 (half day), $125
    • Ricardo Signes - Unicode and Associated Punishments - Sunday 6/18 (half day), $100
    • Mark Jason Dominus - Advanced Parsing Techniques - Thursday 6/22, $75
    • Mark Jason Dominus - Higher Order Perl - Thursday 6/22, $75
    • David Golden - MongoDB with Perl - Thursday 6/22, $99
    • Damian Conway - New Perl - Thursday 6/22, $150
    • Damian Conway - Parsing with Perl 6 Regexes and Grammars - Thursday 6/23, $150

    Call for Speakers: Lightning Talks

    This year there are THREE sessions of lightning talks! Each will have about 10 Lightning Talks of 5 minutes each.

    These Lightning Talks may be serious, funny, or both. They may be given by experienced speakers already giving full length talks or by first time speakers just starting out (this is a great way to get started if you have something to say). If you are a first time speaker you will win a tie with an experience speaker when the schedule is made if it comes to it. Today's first time speaker could be tomorrow's keynote speaker.

    In addition to the five minute Lightning Talks where you get to use your computer, slides, and any other tool, we will also have some Lightning Advertisements. These are only 30 seconds, you don't have to submit a proposal, you don't get any slides, and the only AV assistance offered is a microphone. If you have a BOF to announce or any other short message you can use the transition time that would be otherwise wasted between Lightning Talks to share your message. Just show up before we start and take a seat in the assigned seats in the front of the room.

    Submit your talk here: https://goo.gl/forms/e6cSnnhs0HSVhzNF3.

    Call for Volunteers

    Volunteer Registration Form Here: https://goo.gl/forms/dubrWgPaedd0gH723

    Setup / Cleanup Crew

    On Sunday, we will need volunteers to assist with unboxing materials, placing signs, setting up AV equipment, preparing registration area, and working to make the area aesthetically pleasing. There will be a lot of odd jobs that need to be done.

    On Thursday and Friday, we will need to go through everything that is left over, box it, and ship it out.

    Room Moderator

    The Moderator will be assigned a room for the day (only during breakout sessions). Their responsibility is to introduce each speaker prior to their talk. They work with the Videographer to ensure talks do not start until the videography team is ready to record. They also ensure that their room keeps to the schedule, cuing the speaker to end their talk as necessary. They will provide any special announcements between talks as instructed by the organizer staff.

    Videographer

    Each room will have a Videographer, who reports to the Videography Team leader. They are responsible for recording the talks in their assigned room (except where the speaker has opted-out of being recorded).

    Assistant Videographer

    Performs tasks as assigned by the videographer. Acts as a runner if something is needed in the room.

    Registration Desk

    Assists people with checking in. Serves as an information desk attendant. Assists attendees with retail purchases.

    • Better POSIX chars classes parsing
    • Perl 5.26 syntax support:

      • References declarations
      • ^CAPTURE and ^CAPTURE_ALL variables
      • Perl settings now allows You to choose target Perl version. In case 5.26 is selected, resolve won't check current directory while resolving packages.

    Fixes

    • Lexing of $( and $) inside the match part of regexp. #1435
    • Indentation of here-docs with selection and tab

Type::Tiny 1.2.0 Released

    So, Type::Tiny 1.2.0 (a.k.a. 1.002000 using Perlish decimals) is now available on CPAN.

    Highlights since 1.0.0:

    • Type::Params now has compile_named and validate_named.

      This allows for:

      sub add_pet { state $check = compile_named( name => Str, species => Str, age => Optional[Int], ); my $args = $check->(@_); ...; # do stuff with $args hashref }

      It's faster than the old compile slurpy Dict hack.

    • Type::Tiny's constraint parameter may be a string of code.

      isa => Int->where('$_ % 2 == 0')  # even numbers only
    • Types::Standard::CycleTuple added.

      my $type = CycleTuple[Str, ArrayRef, Int]; $type->assert_valid( [ "foo", [], 42, "bar", [], 21 ] ); # ok $type->assert_valid( [ "foo", [], 42, "bar", [], 2.1 ] ); # throws exc +eption
    • Types::Standard::RegexpRef now accepts blessed objects where $object->isa('Regexp'). This plays better with re::engine::* pragmas.

    • Fixed bug where Types::Standard::Int would sometimes accept an overloaded object. (It never should.)

    • Various performance enhancements and bug fixes.

Perl 5.26.0 Available

    The latest version of Perl, 5.26.0, has just been released.

    Here's the changes since 5.24.1: perldelta.

    I've been using 5.25.9 (developer release) for a while because I wanted the Unicode 9.0 support. This included new features now available in 5.26.0. A couple I particularly liked are:

    Indented Here-documents

    This allows you to now write (after a couple of levels of indentation):

    { ... { ... my $boilerplate = <<~'EOT'; Boilerplate text ... EOT ... } ... }

    Previously, without being able to add the tilde, meant code typically looked liked this (and the readability gains from indenting code were somewhat diminished):

    { ... { ... my $boilerplate = <<'EOT'; Boilerplate text ... EOT ... } ... }
    New regular expression modifier /xx

    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:

    /^([A-Za-z0-9]).*?([!@#$%^&*])$/ / ^ ( [A-Za-z0-9] ) .*? ( [!@#$%^&*] ) $ /x / ^ ( [ A-Z a-z 0-9] ) .*? ( [ ! @ # $ % ^ & * ] ) $ /xx

    It's been discussed here a few times recently, but also note: Removal of the current directory (".") from @INC

    While I was writing this, I was also installing 5.26.0 (under perlbrew). I see it has already completed successfully: so that much works and, at least for me, didn't take very long.

    Hi, there was alot of posts recently concerning books for Perl6. In the Perl Newsletter today, Think Perl6 was announced. A restricted free pdf download is also available, under the Creative Commons License . See Think Perl6 .

    Remember, before commenting, I have not read it yet, but upon a speed-read, it looks like a nice way for Perl5'ers to get used to the more efficient syntax usage in Perl6.

    We're on-line. Finally: http://act.perlconference.org/tpc-2017-amsterdam

    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.

    Call for papers can be found here.

    Hope to meet a lot of you folk there in person.


    Enjoy, Have FUN! H.Merijn

    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.

    The conference website is: http://www.perlconference.us/tpc-2017-dc/

    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)

    The conference is being held in the amazing US Patent and Trademark Office, and will feature an event in the National Inventors Hall of Fame Museum.

    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.
