    kmx has finally responded to the issue I raised more than 3 weeks ago with responses of "fixed" and "closed".

    UPDATE: My mistake - the assertion (below) that the issue is NOT fixed is rubbish. It's just that I can't tell the difference between "5.32.0" and "5.30.2".
    AFAICT, the issue I raised is NOT fixed, but if you visit you'll see that, in addition to the listing of perl-5.30.3 builds, perl-5.32.0 builds (which have been sitting on the Strawberry Perl server for at least a week or two) are, as of a few hours ago, now also officially available.
    That's about all I know ... with little expectation that kmx will provide any additional information.

    @ All German speakers here:

    Next German PM Online Meeting in (cough) 30 minutes.


    Hallo Perlmongers aus den deutschsprachigem Raum,

    Heute, am Dienstag, den 4. August 2020, um 19:30 Uhr ist German-PM Online-Treffen im Jitsi.

    Dank Corona wurde das Online-Treffen mehrfach in Erlangen und Frankfurt ausprobiert. Der Wunsch wurde geäußert, das online neben den Treffen vor Ort weiterzuführen.

    Nimm an der Besprechung teil:

    I'm not the organizer, but I'll use this thread for future announcements.


    on Daxim's request



    Cheers Rolf

Strawberry Perl-5.30.3 is available

    Just noticed that Strawberry Perl-5.30.3 is now available.
    The date given there is 2020-07-13, but I know it wasn't available earlier today. (Looks like the date is the date that perl was built - not the date at which the distro became available.)

    Hopefully, that indicates that 5.32.0 might not be too far away.
    Actually, I build my own perls on Windows and therefore don't rely on the Strawberry project for perl. It's still a very handy reference for me, but.
    And I do look forward to using the updated gcc compiler that usually accompanies new Strawberry Perl major releases.
    Since the mingw-w64 project stopped providing recent builds of gcc (as of a couple of years ago), I've come to rely on Strawberry for my gcc upgrades.

    Anyway ... just thought it was worth mentioning ... and looking forward to a 5.32.0 release soon, with (fingers crossed) gcc-9 or gcc-10.

Malicious module on CPAN

    If you use Module::AutoLoad, consider switching to something else. The module was removed from CPAN as it used string eval on data obtained from the internet.

    More details in the perl.modules e-mail archive.

    Link to the related StackOverflow question with replies from the very author of the distribution.

    I followed the link to r/perl and was pleasantly surprised to see a link to "Perl Weekly Challenges" that seems to be quite active.

    I never participated in the Perl golf on account of me being totally lost or the Perl programming challenges of yore, but I was pretty active with the Pull Request Challenge when it was going. I got a lot out of it and I strongly encouraged any Perl programmers at $WORK I happened to be mentoring at the time to get involved. Some did, and it was very beneficial for them as well.

    In any case, it's no PRC but it looks like the PWCs have been active for quite a few months. Not sure if this is news, but it is new to me. And I don't see how it's fake even tho I found it on leddit, so here you go!

    Update - PRC is back, it seems!! Pull Request Club covered in a lightning talk, Kivanc Yazan - State of Pull Request Club - Lightning Talks - Day 2.

IntraMine service suite

    Dear suPerlatives,

    Allow me to introduce Intramine, an intranet service suite for Windows done in Strawberry Perl and JavaScript that provides sub-second local search of your half a million or more source and text files, among other things.

    Some other things:

    • five-second index update when you change a file, to keep searches current
    • automatic linking for all source and text and image file mentions, with minimal overhead (often none)
    • a really nice file Viewer to browse your files, and see search hits in full context (plus that automatic linking)
    • image hovers in your source and text files
    • Gloss, a markdown variant specifically for intranet use that takes advantage of autolinking and minimizes "computer friendly" overhead
    • scalable services: write your own IntraMine service, with or without a front end, and run multiple instances that can talk to other services
    • Search, Viewer, and Linker service support for 137 programming languages, as well as plain text
    • all original work is covered by an UNLICENSE.

Cor—An object system for the Perl core

    FYI: I've been doing a lot of of work speccing out Cor, an object system for the Perl core.

    You can read about it on the wiki. There are also extensive links on different pages for people to provide feedback.

    Per discussion with Sawyer, the current Perl pumpking, the current plan is that Cor will go into the Perl core. Unlike previous attempts, this one looks like it will really happen. So get your feedback in now.

    To give you a little taste, here's a simple LRU cache written in Cor.

    class Cache::LRU { use Hash::Ordered; has $cache :handles(get) :builder; has $max_size :new(optional) :reader :isa(PositiveInt) = 20; has $created :reader = time; method _build_cache () { Hash::Ordered->new } method set ( $key, $value ) { if ( $cache->exists($key) ) { $cache->delete($key); } elsif ( $cache->keys > $max_size ) { $cache->shift; } $cache->set( $key, $value ); # new values in front } }

    Also, holy carp! I've had an account here for 20 years!

Perl & Raku Con in Amsterdam 2020 - Cancelled due to Covid-19

    Sad news reach us from the Perl & Raku Con in Amsterdam:

    Due to COVID-19, the organizers of the conference have agreed to cancel the event. For both safety as well as with the expectation that a new rule closing organized events over 3 people until June in the Netherlands has made the conferene this year untenable. The conference will continue in 2021 (likely to be in August just as this year was scheduled for). We are looking into the possibility of a remote conference sometime this summer in collaboration with the American conference.

    "Performance Concurrency with the Perl Many-Core Engine"

    A talk on MCE and MCE::Shared, introducing the main features and usage of this powerful framework to parallelize your Perl code and turbo-charge your programs by harnessing the power of all the cores on your machine.

    Hosted by On line (due to the COVID-19 pandemic) at :

    Date: Wednesday March 25, 2020
    Time: 1800 EDT (GMT-4)

    Fellow monks, I prepared this talk (with the assistance of marioroy, the author of the modules) for the Perl Conference 2020 where I was scheduled to present it. Today that conference was cancelled, as has been the Baltimore/DC Perlyglot Workshop where it was also on the schedule. I was scheduled to give the talk at the Charlotte, NC Perlmongers meeting tomorrow; that meeting has been moved on line. The organizer cromedome has allowed me to share the link, so if you have any interest in MCE please join us!


    The way forward always starts with a minimal test.
