  • Posted The Toolchain Summit is only possible with support from our sponsors to NeilB

    The Perl Toolchain Summit (PTS) started yesterday (Thursday 11th May) in Lyon, France. 35 dedicated toolchain developers have assembled for four days of intensive discussions and co-working. Not only does a lot get done in these four days, but we send everyone home with longer todo lists, fired…

  • Posted Specifying dependencies for your CPAN distribution to NeilB

    In this article I'm going to show you how to specify dependencies for your CPAN distributions: the other Perl and CPAN modules that your distribution relies on. This is the fourth article in a series. The

  • Commented on Golang's 'defer' in Perl
    Have a look at Scope::OnExit. There are a number of similar modules on CPAN. I listed the ones I know about in the SEE ALSO section for the AtExit module: https://metacpan.org/pod/AtExit#SEE-ALSO I haven't check to see whether any of them...
  • Commented on Dependency phases in CPAN distribution metadata
    Hi Konstantin, I'll cover this sort of thing in the next article, but to add develop dependencies via Makefile.PL/ExtUtils::MakeMaker you use META_MERGE. For example: META_MERGE => { "meta-spec" => { version => 2 }, prereqs => { develop => {...

    In the previous article in this series we gave a general introduction to the distribution metadata which is included in releases as files META.json and/or META.yml. In this article I'll drill…

  • Posted An introduction to CPAN distribution metadata to NeilB

    All CPAN releases (these days) include a metadata file which has information about the distribution. It can be used by tools like CPAN clients (when installing modules), but it's also helpful for other tool writers, and people analysing the structure of CPAN. The metadata file will be called…

  • Commented on TVPM Tech Talks in Reading, UK
    We've decided to skip the videos. We don't have a camera, but more importantly I coerced people into giving talks saying "it's just us", so it doesn't feel right to spring youtube stardom on them at this late date. But...

    Hi Matthew -- we hadn't planned on recording this. I'll ask the speakers if they would be ok with becoming youtube superstars, and if so, see if someone has a camera....

    I bet a pretty significant percentage of CPAN authors have reason to thank Slaven. The White Camel awards should be coming up soon, and hopefully Slaven will get one this year!...
  • Posted An introduction to MetaCPAN's use of Elasticsearch to NeilB

    This is the second in a series of articles, which we're writing to celebrate meta::hack, our first MetaCPAN hackathon, which is currently (Nov 17th through 21st) taking place in Chicago.

    This hackathon was by invitation only, since it had a very specific goal: completing migration of the l…

    This post was originally going to be an exhortation to potential speakers, to take the plunge and submit a proposal to the London Perl Workshop. I thought I could list some generic types of talks.

    Hacktoberfest is nearly upon us again. If you sign up and then do 4 pull requests in October, you'll get a free t-shirt. Sadly the list of Featured Projects doesn't include any Perl ones, but last year I created a

  • Posted CPAN Day: Tuesday 16th August 2016 to NeilB

    CPAN Day marks the day when the first distribution was recorded as being uploaded to CPAN. That was 16th August 1995, so we've been uploading modules for 21 years now!

    On CPAN Day you could release something to CPAN, send a pull request on someone else's distribution, blog about Perl, or j…

    Hi Dean: turns out I hadn't read the email from the NOC closely enough. The tight diskspace will eventually be resolved, we just need to clear some space to see us through....
  • Commented on Please delete old releases from your CPAN directory
    Hi Alexander, On the automatic cleanup of PAUSE: this has been discussed a number of times. It's a hairy topic, which is why no-one's taken it on, but you're right, we should make it happen. I've opened a github issue...
  • Commented on Please delete old releases from your CPAN directory
    Hi Gabor. I meant to mention that we've identified the heavy hitters, both in terms of authors and distributions, and have started emailing them directly. I'll update the post. You said that "This post might reach a few hundred readers"....
  • Posted Please delete old releases from your CPAN directory to NeilB

    The Perl NOC have informed the PAUSE admins that the CPAN Master is starting to get tight on diskspace. This is only a temporary constraint — at some point there will be a lot more space, but for now we need to free up some space.

    A lot of space is being taken up by old releases, lon…

    Second the motion.

  • Matthew Persico commented on TVPM Tech Talks in Reading, UK

    Thanks. It occurred to me as I was reading this, that we've got over 100 pm groups all doing their own thing and although our cat's stupid tricks make it up to Facebook and YouTube, we aren't sharing that wealth of information.

    I have to talk to the TPF and see if coordinating PM recordings is something that we can help with.

  • Matthew Persico commented on TVPM Tech Talks in Reading, UK

    Understood. Could you at least post the presentation materials somewhere?

    Hmm. I wonder if we could do a PerlPM repo on git hub - one branch for each PM branch. Dated subdirs for the presentations, which could be the actual presentations or a link to where they exist?

    Yeah, I have to flesh this idea out more.

  • Pawel bbkr Pabian commented on Dependency phases in CPAN distribution metadata

    Excellent article!

    Can you briefly describe how do you package Perl 5 ecosystem for _production_ environment? In my case it goes like this:

    1. Build Perl itself. Holy cow, 55MB! Worst bundle ever for slim Docker containers, because it throws everything into one bucket. Develop dependencies (like Pod::Perldoc, Devel::, Benchmark, TAP::Parser::* or CPAN::*), build dependencies (ExtUtils::*, Module::*), runtime dependencies (Unicode stuff and pragmas) and of course tons of stuff no one really uses nowadays (NBDM, ODBM, SBDM interfaces, ptar, zipdetails binaries).

    I truly…

  • 3ee5cf54-f022-4a71-8666-3c2b5ee231dd [openid.stackexchange.com] commented on Golang's 'defer' in Perl

    In your make_upper_caser_iterator example, I'm pretty sure that $fh becoming unreferenced closes the file anyway. So the explicit close isn't needed (except, of course, that you could check the result and handle errors). Also, if your file handle is valid in the child process, you want to close it there too—fork copies file handles, too.

    PS: Watch out for your …
