Perl Weekly #655 - What's new in Perl and on CPAN? What's new in Italy?

Originally published at Perl Weekly 655

Hi there!

After a hiatus of 4 years, it seems the "What's new on CPAN" series is back on Apparently there was already one published December 20 What's new on CPAN - November 2023 and then one on January 9, 2023 What's new on CPAN - December 2023. Thanks to Mathew Korica.

If you'd like to know what's going on with Perl, I'd suggest you watch the presentation of Paul Evans from the recent FOSDEM: Updates from the PSC

And a last minute notification I received from Michele Beltrame that made me quite happy: After some years of stagnant activity, we opened a Telegram group for the Italian Perl community. Link from the web site of the Italian Perl Mongers.

Enjoy your week!

Preload Data::Printer and avoid polluting your code with debug symbols

How to avoid 'use Data::Printer' and still use Data::Printer?

What's new on CPAN - November 2023

What's new on CPAN - December 2023

Module that returns the magic of the file

Demand Data::Printer to dump politely if it doesn't want to

Using peppers with Crypt::Passphrase

Crypt::Passphrase is a module for managing passwords. It allows you to separate policy and mechanism, meaning that the code that polices authorization doesn’t have to know anything about what algorithms are used behind the screen, and vice-versa; thus making for a cryptographically agile system.

Feature release 1.36 of the Date::Holidays Perl distribution

Triggered by yet another contribution from Wesley Schwengle (waterkip) Jonas announces the release 1.36 of the Date::Holidays Perl distribution.

RECAP - The Weekly Challenge - 255

Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Odd Character" and "Most Frequent Word" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.


Impressive use of map, good job done. Keep it up.

Mostly Odd

Use of bag is ideal for this week task. Raku rocks !!!

PWC 255 Odd character cordoctahedra and the most most most frequent word word

Enjoy more than one way to solve the challenge. Truly Perl TIMTOWTDI.

Preel Weeakly

Remember 11111111 is binary of week 255 and is the largest integer which can be represented by one byte.

Perl Weekly Challenge: Week 255

Thorough and detailed discussion of Raku based solution, not to be missed. Keep it up great work.

Frequent Oddities

Once again CPAN module List::UtilsBy makes the life fun as shown in this week solution. Thanks for sharing.

Perl Weekly Challenge 255: Odd Character

Raku powerful features make the end result a cool one liner. You must check it out.

Perl Weekly Challenge 255: Most Frequent Word

Regex, every programmer's friend, once again helping to solve the task. Great work.

Banned Words and Exceeding Letters

BagHash? Never heard before but then I hardly scratch the surface. Thanks for sharing the knowledge.

Perl Weekly Challenge 255

For all Perl fans, here we have solutions in Perl full of magical features. Well done.

Odd Char Seems to be the Most Frequent Word

I find the switch between Perl and Raku is fun to watch. What a great story teller is Packy !!

An odd character’s nearly best word

Perl one liner is showing off the power. Keep it up great work.

The Weekly Challenge #255

Sometimes, you don't need to look anywhere for the solution, just follow the straight path as discussed on the post.

Most Frequently Odd Character

My favourite is the Postscript solution this week and surprising not too hard to follow, thanks for sharing.

The most odd thing

Really enjoy the method signature and return type on Python. I wish Perl had this too.

PWC 255

Perl 4 and Python 1.4? I salute the patience to deal with them. Keep it up great work.

Static Site Generator

Create your own knowledge base

You might know the Perl Maven site. On one hand it is a blog, on the other hand it is a collection of little pieces of examples I collected. I had quite a few cases when I had to repeat some task various times at various clients. I collected the solution on the Perl Maven site and that helped me find these solutions when I needed again. Making my knowledge base public also helped a few other people. Recently I started to rewrite it as a Static web site and the Rust Maven along with a few other sites already uses the Static Site Generator. A few days ago the first person who is not me started to use it. It might be time to invite you too to give it a try!

You joined the Perl Weekly to get weekly e-mails about the Perl programming language and related topics.
