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?

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.

Hello all. I installed Perlbrew to try it out using Perl modules without admin rights. My machine is Linux EOS. When I run a simple perl script it gives error Cant locate Modern/ in \@INC. 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:

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

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 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; } }

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, and

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.

Visual Exploration of Perl Camel at TPRC 24 ConferenceI 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)

I am using Selenium to obtain a numeric value from a website with code such as:

my @divwrap = $driver->find_elements('whatever', 'id'); my $return_value = $driver->find_child_element($divwrap, 'changeValue', 'class')->get_text(); 

This works fine, and returns the correct expected value.

If the value is POSITIVE, it return the plus sign, such as "+64.43"

But if the value is NEGATIVE, it returns a "wide Character" string: "" instead of the minus sign.

So the return looks like "64.43"

Interestingly, I cannot do a substitution.

If I have explicit code, such as:

my $output = "64.43" ; $output =~ s/"/\-/ ; 

... then $output will print as "-64.43"

... but if I try to do the same substitution on the return from the find_child_element function:

$return_value =~ s/"/\-/ ; 

... the substitution does not take... and printing $return_value continues to output "64.43".

Any ideas why it doesn't... and how to solve it?

I’m a dev with 20yoe in mostly Java and js but have various amounts of experience with other languages. I’ve decided that I need Perl in my toolkit because I find it on even the most minimal boxes preinstalled and I can’t always install Java or Js just to do admin things. Typically I use bash for these tasks but I just need a little more ability to abstract than what bash easily provides. What would you all recommend as the place to start? Most guides that I run into assume that I’m a beginner to programming and it feels slow. My normal method of learning a new language is to stumble through building a web server but I’m not sure that the way to go here.

I am working with the IP::Geolocation::MMDB module which replaces the deprecated modules for GeoIP databases.

I am having trouble understanding how to extract data.

my $ip = ""; my $db = IP::Geolocation::MMDB->new(file => "$geolitecitydb"); my $geodata = $db->record_for_address($ip); print Dumper($geodata); 

Using Data::Dumper as above to show the results, I see something like (truncated):
Dumper...........$VAR1 = { 'continent' => { 'geoname_id' => 6255149, 'names' => { 'de' => 'Nordamerika', 'es' => "Norteam\x{e9}rica", 'zh-CN' => "\x{5317}\x{7f8e}\x{6d32}", 'ru' => "\x{421}\x{435}\x{432}\x{435}\x{440}\x{43d}\x{430}\x{44f} \x{410}\x{43c}\x{435}\x{440}\x{438}\x{43a}\x{430}", 'fr' => "Am\x{e9}rique du Nord", 'ja' => "\x{5317}\x{30a2}\x{30e1}\x{30ea}\x{30ab}", 'en' => 'North America', 'pt-BR' => "Am\x{e9}rica do Norte" }, 'code' => 'NA' 

Supposing I just want to grab the value of continent=>names=>en portion (value: 'North America') and write it to a value -- how would I do this? I'm having problems understanding the documentation I'm reading to deal with hashes of hashes.

Most examples I can find online involve looping through all of this; but in my case, I just want to make $somevar = 'North America.' I'd like to repeat it for other data as well, which is returned in this hash.

It feels like something like:

$geodata{city=>names=>en} should work, but it doesn't.

I have been using version 5.22.1 for years, and it did what I needed to do. After all these years, I need some additional functionality, so I thought installing the latest might help.

Which is when I found that ActiveState has changed the installation process totally. Anyway, I went through the installation of the "recommended" version, and installation seemed to go fine.

I then ran the following simple code through both versions.

use HTTP::Tiny; my $url ='' ; my $response = HTTP::Tiny->new->get($url); print $response->{content}; 

Version 5.22.1 runs this fine and gives me the HTML of the page.
Version 5.36.3 gives me the following errors;

IO::Socket::SSL 1.42 must be installed for https support
Net::SSLeay 1.49 must be installed for https support

When I use the old ppm command for Version 5.22.1, it gives me a list of 271 packages installed.

When I used the new "state" command: "state packages", it showed nothing.

So I used "state" to "install" IO-Socket-SSL, and Net-SSLeay, and now those are the only two that show up in the "state packages" list.

But it did not change functionality. The error messages are still there, and no execution.

It doesn't complain about HTTP::Tiny.

I tried installing Strawberry. But it had a problem with a more complex part of my original project, so I went back to ActiveState 5.22.1, which works fine.

Anybody got any ideas about what I need to do to get 5.36.3 actually working?

Its been a long time since i've had to hack some code together so here just asking for advice as to where to start.

I have a group of printers (all have same web interface) on the corporate network. I would like to make a simple script that can login, and upload a config file (really its a list of users that have can scan documents, it doesn't matter what).

I've tried to google this with limited results, so wanted to reach out here to see if PERL would be the best answer for this.

I guess my question is, what modules should I look at to connect to a webpage in order to login then access a page behind the login and upload a file?

I looked into Mechanize but I do not believe it can handle javascript. Any advice or test scripts that do something similar would be greatly appreciated.

I’m currently having to modify a library that used Smart::Match extensively since I can no longer turn off the zillions of lines of experimental warnings in recent Perls. For people who are in a similar situation it’s looking like Data::Compare can replace the situations where I was doing ‘@foo ~~ @bar’, and it’s easy enough to write a “does this hash have this key” helper.

Meta complaint: I was already a bit annoyed at the whole smartmatch “oh whoops actually this is now experimental” saga but now that I’m stuck fixing this breakage I’m $annoyed++. Im getting annoyed enough that I may choose an older Perl that was “good enough” and just stop using the new ones

package LotsOfCode

sub fish {}

sub dog {}

sub cat {}


I'd like to

mkdir ./LotsOfiCode

nano LotsOfCode/ move sub fish{} here

nano LotsOfCode/ move sub dog {} here

nano LotsOfCode/ move sub cat {} here

what do I put in the top of these new files in \LotsOfiCode ?

package LotsOfCode::fish;


package fish; ?


nothing is what I have so far just

sub fish {}

then in

do I go:

package LotsOfCode

use LotsOfiCode::fish

use LotsOfiCode::dog

use LotsOfiCode::cat



do LotsOfCode::fish;

do LotsOfCode::cat;

do LotsOfCode::dog;

I have an input string that has "comments" in it that are in the form of: everything after a ; is considered a comment. I want to remove all comments from the string and get the raw text out. This is a pretty simple regexp replace except for the fact that ; characters are valid non-comments inside of double quoted strings.

How can I improve the remove_comments() function to handle quoted strings with semi-colons in them correctly?

```perl use v5.36;

my $str = 'Raw data ; This is a full-line comment More data ; comment after it Some data "and a quoted string; this is NOT a comment"';

my $clean = remove_comments($str);

print "Before:\n$str\n\nAfter:\n$clean\n";

sub remove_comments { my $in = shift();

$in =~ s/;.*//g; # Remove everything after the ; to EOL return $in; 

} ```

im looking to put my website written in perl that currently runs locally inside apache out on the internet.

I dont want to host myself, and i dont have lots of spare time to config or money to spend for a vps.

Does anyone have experiences and can recommend a webhoster for maybe 10-15 bucks a month where i can just get a simple interface with ssh, where i can put an index.cgi somewhere(dont care if its in cgi-bin or public_html or something else,

i want something where i can just checkout my git repo thta contains index.cgi in its root and just works.

Thank you in advance!

Thanks to a pile of new data added and old data cleaned up (most of that work done by Philippe Bruhat and Aristotle Pagaltzis) and some help from Copilot on the Javascript, there's a lot of new, interesting information on my Perl Steering Council web page -
