  • Commented on Signing CPAN Releases with SigStore
    The main message should be that this is paralleling efforts in other repositories, such as npm and PyPl. No matter the wisdom of this particular technique, any approach is only really useful if the end user doesn't have to coordinate...
  • Commented on AI Contributions to CPAN: The Copyright Question
    I've been goofing around with another angle. What do I do when I commit code that I asked something to generate and then merely direct its improvement rather than typing out code myself? For example, I was evaluating Claude Code,...
  • Commented on Quick and dirty string dumping
    I use the dumper from Mojo::Util, which is Data::Dumper with better defaults. I even pull it out of the module and have it as a string to insert into programs where Mojo is not already around: sub dumper { state...
  • Commented on Shipping a Perl CLI as a single file with App::FatPacker
    This is really good stuff. We're trying to change some of the PerlPowerTools over to fatpacked scripts to have some more flexibility since the hard requirement is single file, drop in scripts....
  • Commented on More dev.to articles on beautiful Perl features
    Keep it up :) I've been posting each article in /r/perl on Reddit, but since they are published on dev.to, Reddit blocks them and special moderator assistance (which I can do myself) is required. No idea why dev.to is blocked,...
  • Commented on perlmodules.net is down for 1-2 weeks
    I was looking for any notice of the API changes, because this would be important for me too. Do you have any pointers?...
  • Commented on Unicode: The Good, the Bad, and the (mostly) Ugly
    You might have more luck with the talk's main title: "Unicode Support Shootout". Tom's Unicode talks were rescued and put on GitHub: tsibley/tchrist-OSCON2011-Unicode I rescued some of Tom's Unicode tools and have them in Unicode::Tussle (briandfoy/unicode-tussle) Also nice is his...
  • Commented on GitHub and the Perl License
    Thanks for figuring this out. Sometimes I think not even GitHub knows how these things work. For myself, I just use the Artistic License instead of the dual license, although there are some modules I adopted and have kept whatever...
  • Commented on German Perl/Raku Workshop 2026 in Berlin - 16.03.2026-18.03.2026
    I messed up in the Reddit post because I read the English which has the start date as May, but it's correct in the German (if March is the actual month, as in the title): The new link: https://www.reddit.com/r/perl/comments/1otqhxo/german_perlraku_workshop_2026_in_berlin/...
  • Commented on German Perl/Raku Workshop 2026 in Berlin - 16.03.2026-18.03.2026
    I put this in /r/perl but fixed up the dates in the title for what was in the body....
  • Commented on Is it still worth adding installation instructions to a distribution?
    I think it's still worth it, and it's not causing problems to include it. I have this in my READMEs. You can install this module with a CPAN client, which will resolve and install the dependencies: % cpan Tie::Cycle %...
  • Commented on A Quick Update on Dancer2 2.0.0
    And you just gave a talk about it: Dancer 2.0!...
  • Commented on A pipe operator exists on perl v5.42?
    As for the pipe operator part of this post, the arrow is not going to do that. A proper pipe operator would feed all of the values from the left hand side to the right hand argument list. The arrow...
  • Commented on A pipe operator exists on perl v5.42?
    This is just normal Perl 5 behavior, although your need v5.16 or later for CORE. Here's a demonstration that we build up in [Intermediate Perl](https://www.intermediateperl.com/) (and as a gist where I might expand this). The problem is that the arrow...
  • Commented on MCE - How to?
    There's also David Farrell's Make your code run faster with Perl's secret turbo module....
  • Commented on When Laziness Isn't
    Crap, this submitted when I was trying to change something. I had an `alias` example right before the `u 14` line. $ alias u="perl -le 'system q(uuidgen) for 1..$$ARGV[0]'"...
  • Commented on When Laziness Isn't
    Heh, that's pretty clever to get to some number of values. However, you didn't need the reference: $ perl -le "system q(uuidgen) for 1..5" 76666A86-7155-4EBF-9ED4-F2625DE3CE55 CA1A8D82-467A-4682-8F96-FA0BE0800676 40850CBF-1A41-4803-BE9C-BD87B548826E 08DD5AB6-EBEC-40E9-B4AB-817708A0A584 8BCC70B1-4430-45C6-AF72-5A839EAE6DD5 There can even be a parameter in there: $ u 14...

  • Commented on Wide character (U+XXXX) in substitution (s///)
    Oh heck, I copied the error above the one I wanted. You can see in the (W locale) that this is a locale error: Wide character (U+%X) in %s (W locale) While in a single-byte locale (i.e., a non-UTF-8 one),...
  • Commented on Wide character (U+XXXX) in substitution (s///)
    If you replace use warnings; with use diagnostics;, you get the longer error messages from perldiag: (S utf8) Perl met a wide character (ordinal >255) when it wasn't expecting one. This warning is by default on for I/O (like print)....
  • Commented on London Perl & Raku Workshop 2024: Recordings & Thoughts
    Thanks for the videos! I empathize with the complexity of video, and it's why I don't do video. Changing a small mistake takes so much time compared to editing a text file. One of the YouTubers I follow did a...
  • Commented on Weather::OWM released on CPAN
    +1 for weather APIs!...
  • Commented on Let's add Git userdiff defaults for Perl and Perl 6
    This is over a decade later, but git now has this in core with many more patterns. See userdiff.c (which you already linked to). You still have to associate the file endings with a the perl driver as you show....
  • Commented on Why does this not work
    You're trying to get a hash value, but you are using parens instead of braces. You get: he's barney (barney). he's fred (fred). Change your code to use braces for the single element access to the hash: $fn{"fred"} = "flintstone";...
  • Commented on Carp::Object, an object-oriented replacement for Carp and Carp::Clan
    Very cool! And, someone remembered something I wrote almost 20 years ago. :)...
  • Commented on System Thinking
    If you want to post anything to /r/perl, know that Reddit has some sort of filter on dev.to. If you message the mods we can approve the link. No idea why this is a thing, but it is in other...
  • Commented on I just discovered Dev.to
    Note that Reddit filters out dev.to links that people submit, so if you have problems with that in /r/perl, contact the mods....
  • Commented on ChatGPT for Perl Learning
    Reading might not be how younger generations consume info, but that's not the problem here. It has nothing to do with age or place in time. People have always looked for shortcuts and for ways to avoid learning. New technology...
  • Commented on ChatGPT for Perl Learning
    I don't think we've had a hard time pumping out docs and examples. The bibliography of Perl books, including The Perl Cookbook, is long. If someone wants to learn Perl, everything they need is in some book....
  • Commented on Ordering Your Tests
    Test::Manifest uses this feature to take the test order from a separate file (t/test_manifest)...
