The current post gives an excellent demonstration of Perl's power with the help of a smart one-liner regular expression replacement in Task 1, thus effectively performing parallel string substitutions. As for Task 2, it provides a solid parsing solution b…
24 Aug
This article provides an excellent technical understanding of Perl Weekly Challenge 387. The best part is the parser created for Task 2, which uses a recursive, non-backtracking regex with code hooks and a unique stack frame, enabling it to count atoms in…
This article offers an impressively straightforward answer, showing excellent problem-solving techniques pertaining to manipulating strings and parsing chemical formulas. Jaldhar's concise, idiomatic Perl and Raku programming achieves a good balance betwe…
24 Aug
Arne’s post is absolutely captivating and easy-to-understand tutorial. It devotes enough attention to logical thinking behind solving problems using Raku language while analysing the code line by line and presenting several valuable coding cases that impl…
24 Aug
The post published by Ali is a great short instance of the power of Perl regex. The approaches used in this post show how to solve the tasks in a clean and idiomatic way with the help of regular expressions, the /e and /g modifiers in only a few lines of …
Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Rearrange Binary String" and "Atoms Count" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

Welcome to a new week with a couple of fun tasks "Dyck Words" and "Secret Santa". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ.
July was mostly spent finishing off a commercial contract to get Magic-v2 and value magic in, so I didn't have much time for other perl-related matters.
2 iteration and the code is fixed.

The author is looking for a (Newtonian) physics library, to support a (2D) game. Something where you simple define an array of objects (position, travel, mass, spin, shape, etc), and then step through time with them - as they attract each other, bounce of…
Data::Printer Like Data::Dumper, but coloured output, and summaries [config option] large data structures. But uses either a lot of, or no vertical space. Dump::Krumo , is better in some ways, but doesn't summarise output, and uses a lot of vertical space.

A long investigation into a bug that might or might not be in the Perl core.
It's heartwarming seeing one of my articles having an impact. In a nutshell Dave shows how you too could easily build a web site for your CPAN module or modules.
GLAM hopes to be a simple abstraction of complex interactive graphics. The initial commit is tested to replicate the rope demo in a previous reddit post. A single line of code chooses the backend graphical layer, the rest of the code is identical for both…
PAGI - Perl Asynchronous Gateway Interface is a specification for asynchronous Perl web applications, designed as a spiritual successor to PSGI. It defines a standard interface between async-capable Perl web servers, frameworks, and applications, supporti…
WebDyne is another web framework. I don't recall every seeing it despite it being on CPAN for 16 year at least. Go check it out and let the author (and us) know what do you think!

Punk is a new MVC web framework we are going to learn about at one of the online sessions. You can already go ahead, try it now, and give feedback to the author.
The German Perl/Raku Workshop 2027 will be held in April. The CFP is already open.

Hi there
You might recall that several years ago I started to post my Perl-related content on the Perl Maven web site. It was pretty successful at that time. Since then the interest in Perl declined quite a bit and with that also the number of a

Robbie has provided a very efficient and practical solution for Perl Weekly Challenge #386 using robust and standard Perl core/CPAN modules. In doing so, he has displayed a very analytical and practical approach and avoided tripping over the standard floa…
In week 386, Peter presents a neat, efficient, and very strong Perl design for the base conversion process. The blog post is remarkable because there is an insightful mention of the special cases, and all the edge cases are taken into account, for example…

This post demonstrates a thorough, organised, and very instructive description of how to solve the Perl Weekly Challenge 386 in various programming languages. It is impressive how Packy knows how to present complex mathematical algorithms in a useful step…
17 Aug
The message outlines a very concise and precise solution to the Weekly Challenge 386 by Perl. The repetition of decimal fractions is modeled by using the knowledge of the geometric series, and W. Luis Mochan utilises the method of cross-multiplication, th…
