We are happy to announce that Geizhals Preisvergleich supports the German Perl Workshop in 2024!
These are some answers to the Week 269, Task 2, of the Perl Weekly Challenge organized by Mohammad S. Anwar.
Spoiler Alert: This weekly challenge deadline is due in a few days from now (on May 19, 2024 at 23:59). This blog post provides some solutions to this challenge. Please don’t read on if you intend to complete the challenge on your own.
You are given an array of distinct integers, @ints.
Write a script to distribute the elements as described below:
1) Put the 1st element of the given array to a new array @arr1. 2) Put the 2nd element of the given array to a new array @arr2.
Once you have one element in each arrays, @arr1 and @arr2, then follow the rule below:
If the last element of the array @arr1 is greater than the last
element of the array @arr2 then add the first element of the
given array to @arr1 otherwise to the array @arr2.
When done distribution, return the concatenated arrays. @arr1 and @arr2.
Hey Dancers! We’re doing an advent calendar this year, and we’d love for you to contribute. Tell us your Dancer success story! Write about a project you worked on that used Dancer, a plugin you wrote, a plugin you love, anything.
December is coming fast, so get your ideas in now. Please reply to this post if you’d be interesting in helping with this year’s advent calendar.
Happy New Year!
This week, we discussed some recent mailing-list threads:
meta experiments continue. They should probably provoke some kind of runtime warning about being experimental, but exact details need discussionGreetings Perl People!
There is a strong official consideration by The Perl and Raku Foundation of including a new kind of track to the 2024 Perl and Raku Conference in Las Vegas.
Survey URL: https://forms.gle/DDPWsNqEsZW8AyWX7
The track would target academic and industrial STEM applications, and emulate in some way traditional science conference tracks; meaning the talks would be based on paper and poster submissions. If this came to pass, the Science Perl Committee would also follow up with the publishing of the papers in an official proceedings of this track. But we need your feedback!
Survey URL: https://forms.gle/DDPWsNqEsZW8AyWX7
Please complete and share the survey link so that we may convince the already overworked TPRC planning committee that it's worth the extra effort :-). You may also express support in the comments section below or email them directly to me so that I may forward them to the TPRF - oodler@cpan.org. There are ongoing discussions in the TPRF Slack also - see you there! A call for volunteers will be made at such a time that this proposal is accepted.
Sincerely,
Brett Estrade

Chairman, Science Perl Committee
After a long time of work, the videos are finally available on Youtube. 20 presentations with a total of 14 hours of airtime review the three days of the workshop and you can watch the things you missed on site.
We would especially like to thank Lee Johnson, who made the recordings, and the presenters, of course, without whom the workshop would not have taken place. The support from our sponsors helps us make the workshop take place.

The recordings of the German Perl Workshop 2023 are organised in the order of the day in a playlist available at gpw2023.
We are planning the German Perl Workshop 2024 again and are already in the final negotiations. As soon as we have a place and date fixed, we will update this post and also make a separate announcement.
Yes, it's true. Config::Tiny now allows you to assign an array of values to a key.
The docs have been updated to include a new section, ARRAY SYNTAX.
Various examples are documented there and in test files. Sample usage:
[section]
greetings[]=Hello
greetings[]=World!
one=two
Foo=Bar
Note: The 2 lines of greetings can be separated by other lines too.
You access these values like this:
say $Config->{section}->{greetings}->[0];
say $Config->{section}->{greetings}->[1]
This patch was kindly provided by Steven Schoch.

These are some answers to the Week 238, Task 2 of the Perl Weekly Challenge organized by Mohammad S. Anwar.
Spoiler Alert: This weekly challenge deadline is due in a few days from now (on October 15, 2023 at 23:59). This blog post offers some solutions to this challenge. Please don’t read on if you intend to complete the challenge on your own.
You are given an array of positive integers.
Write a script to sort the given array in increasing order with respect to the count of steps required to obtain a single-digit number by multiplying its digits recursively for each array element. If any two numbers have the same count of steps, then print the smaller number first.
Example 1
On behalf of the Dancer Core Team, I am beyond excited to present you with Dancer2 1.0.0.
So how did we get here? Why now? I'll cover the specifics in a future blog post, but suffice it to say for now, we're stable, and we've been stable for a long time, but this was never reflected in our versioning. It's beyond time to commemorate that milestone.
If you're expecting big changes, you'll be disappointed that there aren't many on the technical side. Much of what's in this release involves adding some polish in spots, and smoothing out some jagged edges in others. Some important highlights include:
Hello everybody! Welcome back to the Weekly Challenge series, where today we're working on dates again. I like these challenges in particular, for some reason. In this case, we have a rather simple challenge except that it gives us less common date formats than usual.
The challenge gives us a year, month, week(day) of the month, and day of week. Now DateTime provides us with get operations to find WoM and DoW info, but it doesn't provide set operations. For that we need to do a little math. Here's the code below:
This week, Graham was on holidays, so Paul and Philippe:
Quote of the week: “There are features that make the language slow, but those are the features that make the language.”
A plenv plugin to add additional include directories to Perl.
This plugin sets the contents of file .perl-libdirs.
It hooks into plenv-exec command and every time you run perl
or any other command under plenv, plenv-libdirs uses the
.perl-libdirs files to set the PERL5LIB environment variable.
plenv-libdirs makes use of .perl-libdirs files
in the current working directory and every directory
between it and root.
Environment variable PERL5LIB has a list of paths separated (like in PATH)
by a colon on Unixish platforms and by a semicolon on Windows
(the proper path separator being given by the command perl -V:path_sep).
When plenv-libdirs collects the paths from .perl-libdirs files,
the order of the paths follows the order of the directories.
The longer the path to .perl-libdirs file, the higher precedence in PERL5LIB.

You are asked to sell juice each costs $5. You are given an array of bills. You can only sell ONE juice to each customer but make sure you return exact change back. You only have $5, $10 and $20 notes. You do not have any change in hand at first.
Write a script to find out if it is possible to sell to each customer with correct change.

Three Perl releases have been published this past week, containing patches for security issues CVE-2023-47038 and CVE-2023-47039. This kept us busy for the past few weeks (explaining the somewhat thinner recent updates).
Emacs comes with two different major modes to edit Perl code: perl-mode and cperl-mode.
perl-mode is somewhat stuck with the Perl syntax of 5.14, has less features, but a cleaner implementation. cperl-mode is up to date with Perl 5.38 and has deeper understanding of Perl syntax, but a somewhat arcane implementation, most of it written in the previous century.
With all due respect to TIMTOWTDI, maintaining two major modes turns out to be not enough fun in the long run, and last week Stefan Kangas opened a wishlist item to Making perl-mode.el obsolete.
The mail thread shows that some people prefer perl-mode because it is less "colorful" and intrusive than cperl-mode. Therefore, the idea is to enable cperl-mode to (optionally) look like and behave like perl-mode. That way, perl-mode.el can be obsoleted without making those users uncomfortable: perl-mode would continue to exist as a custom theme of cperl-mode.

You are given an array of positive integers, @ints.
Write a script to find out if it is possible to select two or more elements of the given array such that the bitwise OR of the selected elements has at least one trailing zero in its binary representation.

Hi everybody, we've got another two challenges this week, so let's dive into them!
The goal is to see if there's any one number that can be removed to make the set sorted in increasing order. Here's the code:
