#TodayIAchieved a faster implementation of named parameters to extended subroutines via my `Sublike::Extended` #perl module.

Not yet on CPAN until I've given it some more thorough testing to satisfy myself that it's stable and robust, but already it's showing good signs. Subs written using this are now over 30% faster than the equivalent plain perl approach using a slurpy hash.

The speed benefit on top of the existing "it's much shorter and neater to read" that it already had.

Company contacted me a while ago. Their only #Perl dev retired, can't find anyone local, and have a huge codebase to maintain. Too far to commute; they don't allow remote.

They tried again a few months later. Still must be onsite, they can't find anyone, won't pay for relocation. Oh, and it's a junior dev salary.

Months later and they're reaching out to me again. Must be onsite, underpaid, and no relocation.

DBI has been the #Perl #programming language’s standard #database interface module since October 1994 when it was released coincident with version 5.000 of the language. Like Perl itself, it has continued to be a model of #OpenSource development and support.

https://fosstodon.org/@metacpan/113074361244015803

Prior to #DBI’s adoption, programs needed a bespoke compiled Perl 4 for any particular database system (e.g., #Informix, #Oracle, #Sybase). DBI provided a unified API for application and database driver developers.

This "Useless use" message can be easily made by just having a statement with only a string literal inside. The message reads interestingly and rather high context -- meaning: readers need to learn at least a little bit about the concept of context in Perl programming language, to be able to understand that no words in that message are useless or void.

# perl x.pl
Useless use of a constant ("forty-two") in void context at x.pl line 3.

# cat x.pl
use v5.36;

"forty-two";

> I think @rurban might take issue with your use of the word “the.” And […] #RPerl […] compiles a bowdlerized modified dialect that resembles parts of Perl. (Or as you wrote, “RPerl stands for Restricted Perl”: http://rperl.org/faq.html#faq_what)

On an upgrade streak at $work

I'm migrating a lot of #perl applications to 5.40 (released 2024-06-04)

Some of those applications were still running on 5.18 (released 2013-05-18)

The most I've had to change was some mis-feature that a third-party library deprecated and removed in the last few years. Everything else Just Works™

is my linux-kernel vendor tree a bit challenged in it’s logic - is it the mainline tree or do i not understand perl?

these two ifs do the same… right? and does perl do “do IF x” instead of “IF x DO”?

trying to get htmldocs out of my vendor kernel atm

I accidentally discovered that's entirely possible to implement an entire blog as a #Perl one-liner

This is a terrible idea so I'm definitely going to keep expending it

“The ‘Go to Line’ panels will now disregard commas and periods in entered line numbers, because that's apparently a thing.”

The #Perl programming language allows single underscores in numeric literals to aid readability: https://perldoc.perl.org/perldata#Scalar-value-constructors

Commas, dots, spaces, underscores, apostrophes, and even half- or thin spaces are used to group digits depending on the country and context: https://en.wikipedia.org/wiki/Decimal_separator#Digit_grouping

It's a thing.

The backwards compatibility of #Perl software is wonderful. That’s why it’s all the more jarring when you find a package that doesn’t work. This is the story of a 15-year-old bug that I managed to track down and, fortunately, resolve.

- In the regex section, include a blurb for "/r", "/a" & "/aa" flags.

- In the "sub" section, show the the version with signatures, stable since v5.36.

I was going to suggest addition of a blurb about try-catch(-finally), but even for v5.40 that is listed as "partly experimental" 😫

What do you think about making (me) a new version of this here https://learnxinyminutes.com/docs/perl/
(I like the way the most important features of a programming language are summarized)
where modern Perl features are explained (e.g. subroutine's formal parameters etc.)?

What else would you like to see in such a short introduction without wanting to include everything that has been available in Perl for some time?

@kevingranade @Uilebheist At some point, a penny drops.

"Oh! Why not just go all in with #perl? It is – after all – Open Source."

I dunno, maybe start by looking at the man page, which is mentioned along with the official #Perl web site when you run `perl -v` to see what version you’ve got?

They’re gonna have an interesting time when #Apple makes good on its five-year-old deprecation of #Perl from #macOS: https://TidBITS.com/2019/06/25/apple-to-deprecate-scripting-languages-in-future-versions-of-macos/

#PHP and #Python 2.7 already got the axe.

Current macOS #Sonoma 14.6.1 ships with #Bash 3.2.57 (deprecated in favor of #Zsh), Python 3.9.6, Perl 5.34.1, #Ruby 2.6.10, and #Tcl 8.5.9, all of which issue deprecation warnings on startup.

Apple to Deprecate Scripting Languages in Future Versions of macOS - TidBITS

Apple says future versions of macOS won’t include a number of open-source scripting languages. The impact of this change will vary depending on the audience, but it will affect more people than you might think.

29 years ago, on 1995-08-16, #CPAN received its first module upload. Like #Perl, "it continues to flourish into its third decade thanks to a vibrant community of users and developers."

Celebrate the occasion with a weekend project to:

- upload a new distribution or a new release
- contribute to a project which keeps your solutions possible
- write a post about your favorite module
- thank, support, and hire the maintainers you depend on

Happy CPAN day, and happy hacking! How do you celebrate?

For $work I am currently forced to write some #PHP. I am not used to that and can probably be considered biased 😅

But I really have a hard time working on #PHPunit tests because I find many of its methods are not clearly documented. It seems to have loads of examples that help you getting into it but extending existing code is hard when you can’t look methods by name …

#Perl’s Test-Simple was always great and adopting its successor Test2 was a pleasure with its great docs! 🤩
