Welcome to a new week with a couple of fun tasks "Zeckendorf Representation" and "Find Celebrity". 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.
Syntax::Highlight::Engine::Kate provides Perl programs with robust syntax highlighting using the same engine as the Kate editor. The latest update fixes Issue #23 in Template.pm: the testDetectSpaces() regex was corrected, ensuring only spaces and tabs ar…

Run::WeeklyChallenge is a small but useful CPAN module that helps you automate running solutions to challenges from The Weekly Challenge site by passing one or more sets of JSON‑formatted inputs to your code. It cleanly wraps your solution logic and input…
Version 0.28 of App::Test::Generator, the black‑box test case generator, has just been released with improved schema extraction and test generation accuracy, tightening detection of getter/setter methods and better typing in generated tests. These enhance…
The announcement of PAGI::Server 0.001017 highlights experimental HTTP/2 support built on nghttp2, bringing both cleartext h2c and TLS‑based HTTP/2 to Perl web services with automatic protocol detection and solid h2spec compliance. The write‑up explains w…
This article highlights one of Perl’s unique strengths, the local keyword, showing how it enables temporary, dynamic changes to global variables without permanent side effects. With clear examples manipulating %ENV, special Perl variables and even symbol …
The post previews Max's talk at the German Perl Workshop 2026, exploring how modern AI coding agents from Anthropic and z.ai can assist with Perl development, what differences exist between the models, and tips for getting them to write good code. It’s an…

The post reflects on the challenge of rational decision‑making with a quirky, human‑centred anecdote, weaving in the idea that structured data models, like decision trees, can help bring objectivity to complex choices. The post’s blend of storytelling and…
In This week in PSC 215, the Perl Steering Council covered a deep discussion around legal identifier name restrictions for security without reaching consensus and planning to broaden the conversation beyond p5p, tackled the challenge of an absent maintain…
It’s great to see the announcement for The Perl and Raku Conference 2026 (TPRC) taking shape, with registration opening and plans underway for a vibrant community gathering in Greenville, SC this June. The post reinforces the value of bringing Perl and Ra…

Hi there,
Perl's asynchronous ecosystem continues to grow, enabling developers to build non-blocking, responsive applications with ease. Modules like IO::Async, async features in Mojolicious, and helpers for asynchronous database operations (suc

This article compares three elegant methods for the string reduction problem. The methods are presented in three different programming languages: Perl (using regular expressions), Python (using recursive regular expressions), and Go (using a stack-based a…

In this article, you can find an excellent and easily read comparison of how each of Go, Python and Perl treats returning multiple values from a function, with good examples for each and some commentary on why certain designs are idiomatically preferred i…

Both parts of The Weekly Challenge #359 are clearly explained, with detailed explanations of the logic behind the solutions and concrete examples to help you understand how each solution works, in either Python or Perl. By providing a solution in both Pyt…

This blog post clearly presents The Weekly Challenge #359 - Roots and Digits (Digital root task). It is a very clean write-up making use of Raku code and does not use extraneous conversion methods. The attention to algorithm and cross-language consistency…
These two tasks were solved cleanly by providing clear context for each task with examples demonstrating how the tasks could be solved using idiomatic features of Perl 5.36. The logic used for both tasks can be easily read, and uses the core modules in a …

This approach is a good example of intentional design and practical implementation. The approach to handling very large integer strings uses the digital root function; the string reduction uses a simple loop. Peter also considers edge cases, such as case …

The post examines TWC359 comprehensively and insightfully via 4 programming languages (Recursive & Iterative Solutions). They show their vast knowledge of specific Languages through examples such as; Elixir using Integer.digits(), Raku displaying its full…

This clean and clever solution combines methods for both problems into one very helpful implementation. In the first case, digit summation and computing the persistent product were both implemented as a clear, fully-documented do...while construct. In the…
This article provides ready-to-use versions of the Digital Root and String Reduction programs written in Perl, including a concise example showing what the results should look like. It uses clear, idiomatic programming style while giving short, simple exp…

A robust method has been found for addressing both TWC359 issues and demonstrates a high degree of clean and streamlined implementations across several languages. The explanation of how to calculate the digital root includes two approaches: the first uses…

Task 1, Digital Root, uses a Perl implementation with the Math::Prime::Util's todigits and vecsum to effectively calculate roots of various number bases with great efficiency, along with an alternative J solution using the "Fold Single" conjunction for pa…
The answer presented here provides two great results for the TWC359 problems; both are simple and elegant solutions. The calculation for the digital root solution is driven through the length of the $root (using while length($root) > 1); it is a clever wa…

This article provides two elegant solutions for the Raku programming language, which illustrate both Raku's clean syntax as well as the practical application of Raku's features. The digital root implementation uses method chaining features of Raku's expre…
9 Feb
Using the power of Perl's capabilities, the provided solution provides an elegant solution to each of the two TWC359 challenges. Task 1 makes efficient use of a concise while loop to compute digital roots and persistence in less median time than most stan…
Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Digital Root" and "String Reduction" 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 "Text Justifier" and "Word Sorter". 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.
This month I managed to finish off a few refalias-related issues, as well as lend some time to help BooK further progress implementing PPC0014.

Starting from December I organize online events where we contribute to open source projects. This report is about the Perl-related contributions in January. BTW the next event is tomorrow. Sign up here
Would you like to have a tool that would look at your code-base and generate a perltidy configuration file that matches it?
It is more like a questionnaire, but you can discuss the answers.
'Perl is my cast-iron pan - reliable, versatile, durable, and continues to be ever so useful.'
Expressiveness of the Perl programming language. Perl vs other languages : Compare facts, not opinions.
BLOCK : sequence of statements; Lexical scope; Lexical scopes in Python are not like Perl; Lexical variables; Shadowing variables from higher scopes; Lexical pragmata

Hi there!
6 years ago we had an edition in which I wrote a bit about Perl on LinkedIn. Back then I collected some basic stats about the Perl groups on LinkedIn. I checked them again: The Perl Mongers group has 7,635 members (down from 8,283). Th
…
There are now some 40 organization listed, thanks in no small part to the people in the Perl community who suggested them.
This is the video recording from December 2025. It includes some explanation on how to find a Perl module to contribute to and we also make some small contributions. For similar events check out the OSDC Perl page.
