Perl is growing and adapting to the modern times, just like a new shiny Plug-In Hybrid car. Plug-in hybrid cars have the best of both worlds, an electric motor that has an average range of 20-60 miles and after its range is depleted it goes on the good old reliable gas motor for a few hundred miles.
Perl has many new shiny tech ( think of this as the Electric motor side of the Plug-In Hybrid car ) like Dancer2, Mojolicious , Starman and now COR which is a new OO system that is part of the language ( and many other cool new cpan modules that I might have missed * feel free to share your favorite new cpan module in the comments)
Perl has done a good job at keeping backwards compatibility ( now think of this as the gas engine side of the plugin hybrid car ) where many companies can still reliably run its perl code ( even after upgrading perl and obviously a few tweaks in the codebase here and there )
The Perl community is still active and its cpan modules continue to be maintained. Yes we have experienced a shrinking in the Perl community but the community has maintained a focus on improving the core modules that are shipped in the language and has paid close attention to widely used cpan modules ( read up on cpan river model - https://neilb.org/2015/04/20/river-of-cpan.html )
If you used to write Perl code or your curious about it then this is the best time to give Perl 5.40 a try and play around with some of its new web frameworks, cpan libraries and its new OO system COR.

Those who've been around long enough know that the use of programming languages was almost a religion a few years ago. For example, the .NET community made no secret of being a sect that branded other technologies as the devil's work. Admittedly, the Llama book was also considered a bible.
Until 20 years ago, Perl was regarded as an elite technology that one could boast about even barely mastering. Getting started with Perl was and still is tough and requires motivation. The reward for building Perl skills often comes years later when you calmly realize that even 10-year-old scripts still perform their duties perfectly - despite multiple system environment updates. Generally, even unoptimized Perl programs run more efficiently than new developments with technologies sold to us as the "hot shit."
One of Perl's top application areas is high-performance and robust web applications in mod_perl/2. To my knowledge, there's no comparable flexible programming language that can interact so closely with the web server and intervene in every layer of the delivery process. The language is mature, balanced, and the syntax is always consistent - at least for the Perl interpreter 😉 If you go to the official mod_perl page (perl.apache.org) in 2024, it recommends a manual written over 20 years ago, and even the link no longer works.
As a Perl enthusiast from the get-go and a full-stack developer, I feel today that - albeit reluctantly - I need to consider a technology switch. Currently, I'm still developing with mod_perl/2 and Perl Mason. As long as I'm working on interface projects, I'm always ahead of the game and can deliver everything in record time. However, when it comes to freelance projects or a new job, it's almost hopeless to bring in Perl experience, especially in Europe.
Throughout my career, I've also used other technologies such as Java Struts, PHP, C/C++, Visual Basic .NET, and I'd better not mention COBOL-85. I've always come back to Perl because of its stability. But I'm noticing that the language is effectively dead and hardly receives any updates or is talked about much. If I were forced to make a technology switch for developing full-stack applications, I would switch to React or Django. It's a shame.

I have been a Perl guy for 30+ years and have had the great idea to upgrade the Perl version of my large Perl APP to 5.40; after a lot of fiddeling around and overriding some Makefile.PL files I got the code and all required libraries to work on an AlmaLinux 9.4. Hoewever I am stuck on getting it to run locally on MacOS 14.5.
The two libraries currently roadblocking are Net::SSL and DBD::MariaDB. I am not fluent enough in C to understand how and if I can get things sorted; anyone able to help? Full compile errors below.
Net::SSL

Found libraries 'ssl, crypto, z' *** THIS IS NOT AN ERROR, JUST A MESSAGE FOR YOUR INFORMATION *** Do you really need Crypt::SSLeay? Starting with version 6.02 of LWP, https support was unbundled into LWP::Protocol::https. This module specifies as one of its prerequisites IO::Socket::SSL which is automatically used by LWP::UserAgent unless this preference is overridden separately. IO::Socket::SSL is a more complete implementation, and, crucially, it allows hostname verification. Crypt::SSLeay does not support this. At this point, Crypt::SSLeay is maintained to support existing software that already depends on it. However, it is possible that your software does not really depend on Crypt::SSLeay, only on the ability of LWP::UserAgent class to communicate with sites over SSL/TLS. If are using version LWP 6.02 or later, and therefore have installed LWP::Protocol::https and its dependencies, and do not explicitly use Net::SSL before loading LWP::UserAgent, or override the default socket class, you are probably using IO::Socket::SSL and do not really need Crypt::SSLeay.

I have a Mac M1 chip laptop.
While I have managed to install a couple of modules, most fail to install.
I tried perlbrew, but that was a struggle to even get it to install perl itself, but when it was installed it wasn't working the way I needed it to.
Just wondering if I am missing something with CPAN or if this is an issue because it's an M1 chip?

How to use perl v5.40's boolean builtins in Mojo::Pg queries
The final installment in the series:
"The-Quest-For-Performance" from my blog Killing It with #perl
Discussing #python #numpy #numba, #rstats #openMP enhancements of Perl code and #simd
Bottom line: I will not be migrating to Python anytime soon.
Food for thought: The Perl interpreter (and many of the modules) are deep down massive C programs. Perhaps one can squeeze real performance kicks by looking into alternative compilers, compiler flags and pragmas ?

I would be interested to know why you chose Perl and how long you have been using it and what for.
I have just returned to Perl after many years away, think decades rather than a couple of years. Consider me a noob as I've long forgotten anything I knew about the language.
I run a small home webserver, Apache on Windows 10 with Strawberry Perl, and recently started some projects starting with moving away with things like Google Analytics and going back to some old log analyzers such as AWStats, which is still being maintained, and W3Perl, which is not. Even more recently I have started using Ringlink.
Perl is still being developed, Strawberry, Active State, CPAN etc. but lost out to PHP and Python. Just like COBOL, I can easily imagine thousands of systems depend on Perl.

A couple of data/compute intensive examples using Perl Data Language (#PDL), #OpenMP, #Perl, Inline and #Python (base, #numpy, #numba). Kind of interesting to see Python eat Perl's dust and PDL being equal to numpy.
OpenMP and Perl's multithreaded #PDL array language were the clear winners here.

How do I make Emacs know that I am using perlbrew and not system Perl? Or how do add the perlbrew PATH to global \@INC? I also have setup Devel::PerlySense inside Emacs following the module documentation. I installed some modules using cpanm client. I'm new to Perl and Emacs and sometimes I'm lost n doesnt know what I'm doing lol 😀 Appreciate your pointing me to the right direction. Below are some log details:

An OpenAI Chatbot in Perl
The OpenAPI::Client::OpenAI module is very low-level. We show how to write a wrapper around it for a clean interface with production code.curtispoe.org
I am fairly new to Perl. I did a lot with it in the mid 90s and came back about 8 months ago. There is a lot I dont know and probably a lot of things I have forgotten.
I picked up Perl to write a couple of applications that I was hoping could run on MacOS, Linux,OpenBSD, and Windows. Perl runs on all of them and many come with Perl built in. Simple scripts I have written run pretty well. (Lets forget about Windows for now).
When I start using libraries(packages?) there is a world of hurt.
Now some libraries pretty much usually work, but many do not. Which works and which do not seems to be dependent upon the operating system and distro.
Then I have to start with what version of Perl is running everywhere. That is annoying.
I end up spending a lot of time on a new machine when I want to run my application, doing nothing else than trying to get the libraries installed.
So I decided to adopt PerlBrew (havent tried it on OpenBSD yet) That should give me a stable version across the differnt platforms.
Then I decided I wanted to write a shell script that would handle installing all of the libarires I might use once and for all so I would know they were all accounted for.
perlbrew exec -q --with perl-5.40.0 cpanm install DBI
Then libraries I have pulled from CPAN do not work.
Google here and Google there.
Ok install GCC and make (I should have known this) More problems:
I found a few of these: "Why are you using CPAN for this? Use the compiled packages that come with <OS><type>"
Hmm I would have thought that CPAN shold be the best source? How do I know what exists as pre built packages on what platform?
Using apt search "perl" or "-perl" or "perl" does not help that much.
I have XML::LibXML working on Mac but getting it working on Ubuntu 22 I have been able to do. I have even tried to start OpenBSD yet)
Is writing cross platform applications in Perl meant to be this difficult?
Should I avoid libraries at all costs and write an aweful lot of code myself?
Is there an easy way to guess what libraries will almost certainly work and what libraries will most likely never work? Some kind of warning system?
Should I look into using pp? I havent yet figured out how to make it compile for Ubuntu,MacOs,OpenBSD yet.
In GoLang its a couple of flags to set for each architecture and off it goes.
ShouldI look into Par files? (or was it Far) that are supposesd to contain the nessescary libraries within itself?
What am I doing wrong?
Libraries in my current set Given all the experimenting some of them are now wrong.
Array::Set, Array::Unique, Bundle::LWP, Data::Dump, Data::Dumper, DateTime, DBD::SQLite, DBI, Digest::file, Digest::MD5, Digest::MD5::File, File::Basename, File::Compare, File::Copy, File::Find, File::Find::Rule, File::Glob, File::Path, File::Slurp, File::Spec, Image::ExifTool, Image::Info, IO::All, List::Compare, List::Gen, List::MoreUtils, List::SomeUtils, List::Util, List::UtilsBy, Log::Minimal, LWP, LWP::Simple, Path::Tiny, Term::ANSIColor, Text::Fuzzy, Type::Tiny,Moose,MooseX::Types,WWW::Mechanize

Repository of examples using Perl and Assembly together
You may have noticed the slow pace of Corinna development. As it turns out, there's an easy way to speed up the development: tell Paul.
I had a call with Paul "LeoNerd" Evans last night and this, including his email address, is being shared with his permission.
As you might imagine, being a core Perl developer, Paul has many things on his plate. Currently has has tons of PRs against the Perl core, he's doing new work such as experimenting with data checks (don't call them "types"!), and is active on the Perl steering council and in P5P. However, he's previously mentioned that he doesn't get much feedback on his work. For adding something as important as Corinna, just blindly adding it without hearing from the community is bad. Yes, we had a multi-year design phase and Corinna is much better for it, but that doesn't mean it's perfect and we don't want to screw this up.
So here's where you come in. Email Paul at leonerd at leonerd.org.uk. Tell him your thoughts about Corinna. He's he one implementing it and working in isolation as he is, despite his work with Object::Pad, isn't good. Tell him what you like, what you don't like, what you'd like to see next, what bugs you've encountered, and so on. Without hearing from you, he has no way of judging community thoughts/support for this project, so he needs your help.
If you'd like a quick refresher on the new syntax, I've written a short introduction. Here's a dead-simple LRU cache written in the new syntax:
use feature 'class'; class Cache::LRU { use Hash::Ordered; field $cache = Hash::Ordered->new; field $max_size :param :reader = 20; method set( $key, $value ) { $cache->unshift( $key, $value ); # new values in front if ( $cache->keys > $max_size ) { $cache->pop; } } method get($key) { return unless $cache->exists($key); my $value = $cache->get($key); $cache->unshift( $key, $value ); # put it at the front return $value; } } submitted by /u/OvidPerl

Parallel Perl/C applications without tears using OpenMP: Controlling the OpenMP environment
My job has led me down the rabbit hole of doing some scripting work in Perl, mainly utility tools. The challenge being that these tools need to parse several thousand source files, and doing so would take quite some time.
I initially dabbled in doing very light stuff with a perl -e one-liner from within a shell script, which meant I could use xargs. However, as my parsing needs evolved on the Perl side of things, I ended up switching to an actual Perl file, which hindered my ability to do parallel processing as our VMs did not have the Perl interpreter built with threads support. In addition, installation of any non-builtin modules such as CPAN was not possible on my target system, so I had limited possibilities, some of which I would assume to be safer and/or less quirky than this.
So then I came up with a rather ugly solution which involved invoking xargs via backticks, which then called a perl one-liner (again) for doing the more computation-heavy parts, xargs splitting the array to process into argument batches for each mini-program to process. It looked like this thus far:
my $out = `echo "$str_in" | xargs -P $num_threads -n $chunk_size perl -e ' my \@args = \@ARGV; foreach my \$arg (\@args) { for my \$idx (1 .. 100000) { my \$var = \$idx; } print "\$arg\n"; } '`; However, this had some drawbacks:
- No editor syntax highlighting (in my case, VSCode), since the inline program is a string.
- All variables within the inline program had to be escaped so as not to be interpolated themselves, which hindered readability quite a bit.
- Every time you would want to use this technique in different parts of the code, you'd have to copy-paste the entire shell command together with the mini-program, even if that very logic was somewhere else in your code.
After some playing around, I've come to a nifty almost-metaprogramming solution, which isn't perfect still, but fits my needs decently well:
sub processing_fct { my u/args = u/ARGV; foreach my $arg (@args) { for my $idx (1 .. 100000) { my $var = $idx; } print "A very extraordinarily long string that contains $arg words and beyond\n"; } } sub parallel_invoke { use POSIX qw{ceil}; my $src_file = $0; my $fct_name = shift; my $input_arg_array = shift; my $n_threads = shift; my $str_in = join("\n", @{$input_arg_array}); my $chunk_size = ceil(@{$input_arg_array} / $n_threads); open(my $src_fh, "<", $src_file) or die("parallel_invoke(): Unable to open source file"); my $src_content = do { local $/; <$src_fh> }; my $fct_body = ($src_content =~ /sub\s+$fct_name\s*({((?:[^}{]*(?1)?)*+)})/m)[1] or die("Unable to find function $fct_name in source file"); return `echo '$str_in' | xargs -P $n_threads -n $chunk_size perl -e '$fct_body'`; } my $out = parallel_invoke("processing_fct", \@array, $num_threads); All parallel_invoke() does is open it's own source file, finds the subroutine declaration, and then passes the function body captured by the regex (which isn't too pretty, but it was necessary to reliably match a balanced construct of nested brackets) - to the xargs perl call.
My limited benchmarking has found this to be as fast if not faster than the perl-with-threads equivalent, in addition to circumventing the performance penalty for the thread safety.
I'd be curious to hear of your opinion of such method, or if you've solved a similar issue differently.

I need some help with the old Perl Gunnar Hjalmarsson's Ringlink program on my site. The forms work, the database gets added to and everything seems ready to go except for the email functions that depend on sendmail.
I have tried several things, installed the CPAN dependencies the program needs, tried Auron SendEmail and other programs and have thoroughly confused myself.
There's a test installation on my site, with the admin and password are both 'test'. There are copies of the CGI files and probably what needs looking at are rlmain.pm, rlconfig.pm and sender.pm
I am running Apache 2.4.54 on Windows 10 with Strawberry Perl installed. I am using the last published version Ringlink (v3.4)
I know this is an old program and the project probably not worth pursuing, but I really would like to give this a go to get it working and would be grateful for any suggestions.

Damian on top form as always. The modules this talk is based on are, of course, all both brilliant and incredibly useful. But the thing that's really impressed me here is the way he has taken some of his modules from a couple of decades ago and replaced them with calls to LLMs. That's food for thought.

 | I was lucky enough to attend the perl and raku conference this year and had a great time meeting lots of awesome people. I am primarily a designer by trade but do code as well. At the conference, I explored a number of original depictions of the perl camel for fun and this one was my favorite. The idea was to bring a strikingly modern feel to the Perl Camel. Loose inspiration for this symbol is code llama and p****n. This design exploration felt like my way to hack something during the conference! The idea behind this simple symbol is that it could work nicely at very small sizes while still being visually clear. The font is a free open-source display font called Jaro. the first image was also a concept of placing "Perl" in the camel symbol to strengthen the association between the "perl" and the camel symbol as this may be helpful for new developers. I could spend much more time on this but thought I would share! Love it? Hate it? Let me know what you think (especially if you like it) submitted by /u/North-Clue-2313 |

My site got exploited the other week. I had a backup of my WordPress domain, so after importing the backup, most of the infected files were gone. However, some files outside the public_html folder were infected. I deleted those files, and my website loads up fine. Just wondering, is there a way I can restore those files without having my hosting company reinstall Perl?
Thx in advance.

Sorry I didn't get this out here earlier (and it's an xpost from Perlmonks), but Perl Community (parent org of the Science Perl Committee that is initiated the Science Track) is giving out a "peoples choice" award at the end of Conference Lightning Talks. It's sincere gesture from us and allows anyone to vote for anyone in the Perl community at large, as a "thank you" from us.
The Science Track talks have been great, some are even starting to come online. Thanks to everyone who made this happen, especially the TPRC Planning Committee.
