The Perl steering committee have continued to work on the forthcoming release candidate of Perl through their ongoing triage efforts. Their current efforts include reviews of the test reports for the HTTP::Tiny module, the generation of draft perldelta do…
TPRC is happening very soon! If you haven’t registered, it’s not too late! We’d still love to see you in Greenville SC June 25-29.

Hi there,
If you are free between 25-29 June then there is a global event, The Perl and Raku Conference (TPRC) 2026, happening in Greenville. TPRC 2026 is an exciting opportunity for many people across the development, engineeri

In this post, Simon analysed the issue into smaller pieces/steps made it easier for implementation to remain very readable and maintainable. A strong resource for developers wishing to observe how simple, idiomatic methods can more elegantly achieve strin…

Roger's article provides an excellent comparison between different programming languages by demonstrating how language paradigms solve the same algorithms for sliding windows and substring matches, thereby providing significant educational value to the re…
Reinier made use of Perl's built-in string matching capabilities to efficiently find all pairs where one of the strings serves as both the beginning and end of one of the other strings. This showcases a great example of writing efficient, clear code to so…
In this article, Reinier discusses how to efficiently leverage Perl's string manipulation and logical checks to confirm if input strings share overlapping character sequences with the least amount of code. This article is an excellent resource for learnin…

Peter offers a refreshingly simple and useful way to accomplish this task using only Perl. He places an emphasis on keeping the code readable, ensuring UTF-8 characters can safely contain more than one byte, and maintaining a high level of performance in …
This post provides a great, multi-lingual breakdown of the challenge with clean idiomatic solutions in Perl, Raku, Python and Elixir. By demonstrating how each of the programming paradigms handle the same logic, Packy provides educational value beyond mea…

W. Luis Mochan employs the expressive capabilities of the Perl language in order to create solutions that exhibit exceptional brevity with no extra syntax or words. This will definitely capture the interest of developers looking for clean and functional s…

Jorg takes a multi-paradigm approach to solving The Weekly Challenge #377 in both Perl and J (the array-processing language). This article showcases Jorg's technical knowledge because he generalises the first task from its minimum definition and well-orga…
The article compares Perl and Raku solutions for Week 376 of the Challenge and illustrates how the two languages are different in terms of their evolution. Specifically, it illustrates how Raku provides a more modern set of high-level features (e.g., buil…

This article offers a great introduction to the Raku language through its implementation of the The Weekly Challenge #377, specifically the use of native Raku functions, such as .flip and .combinations. The code is well-written, typical of Raku, and fully…
Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Reverse Existence" and "Prefix Suffix" 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 "Second Largest Digit" and "Sum of Words". 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.
Time::Str parses and formats date/time strings across 20+ standard formats, with an optional C/XS backend and nanosecond precision. The previous post, Introducing Time::Str, covered parsing and formatting. This one covers two additions, time zones and lea…
Hi there!
In the recent weeks I looked at a lot of MetaCPAN profiles (aka. author pages) such as that of MANWAR. If I could also find their LinkedIn profile I invited them to connect via LinkedIn. (If I have not sent you an invitation yet, then

In this blog post, Simon's clever use of the bitwise XOR operator (^) as a parity check for a chess board is very creative. Additionally, he shows a well-organised and simple method of utilising re.split and list comprehensions to find the position of wor…

A general description of a previously completed task, this post shows a real-life application of code reuse. Roger created a nice, modular solution to decode coordinate mathematics (on the basis of (x+y) mod 2) by cleanly wrapping the existing helper func…
By using an elegant mathematical approach to the parity of squares on a chessboard, along with an incredibly efficient, single-pass regular expression, this code shows immense technical skill. The code also uses multi-line lookaheads, HTML tags, and back …
This post gives a very clear, well-organized, and visually intuitive representation of how to solve the programming challenge "Chessboard Squares". Explicitly laying out the grid coordinates with their appropriate color will provide an excellent foundatio…
8 Jun
This solution offers a very neat, simple, and mathematically pleasing method for solving the chessboard parity problem. Peter has effectively utilised the ASCII values (ord) of the column letters as well as the numeric row values to reduce a spatial coord…
A well-structured and very interesting review of Perl Weekly Challenge 376 is presented with a reference to principles from a popular culture item. Packy clearly illustrates the elegant way to process text in the real world while exhibiting outstanding te…
Matthias presents an analytical and well-defined solution to the difficulties presented by Challenge 376 through the use of well-separated parsing and formatting, clear comments on the use of regular expressions, and the submission of a clear and clean so…
The excellent demonstration of the capabilities of Perl as a function-based programming language is shown through this post with extremely short and idiomatic solutions. Luis Mochán has used expressive, single-line statements to convert complicated constr…
8 Jun
An unusually clear yet detailed solution is provided in this blog post, as it combines clean, idiomatic code examples with short technical explanations about how to use regex to parse doubled words and how to compare two mathematical coordinates. Complex …

Jorg provides a very concise and mathematically elegant solution for the colorisation of a chessboard. By recognising that under mod 2 operations the coordinate bases are completely annihilated, implementations can be created in both Perl and J using only…
8 Jun
Bob presents a creative solution to a challenging text processing issue by using a well known yet little used built-in feature of the Perl. The result is an elegant mechanism for bypassing tokens through a clearly documented and separated mechanism of bac…

The post offers an orderly, aesthetically pleasing way of solving the Weekly Challenge problems using the modern-day features of Raku syntax. With the use of well-defined subset custom types to strongly validate input and a simple, tokenising object-orien…

It was created while working on the DBIx::Class integration with GraphQL. Using this module, it is so easy to build GraphQL API.

Perl client module for FalkorDB. This code was mostly generated using AI tools and has not been checked manually yet.

After DBIx::Class integration with GraphQL, my immediate task was to make the process easy as it doesn't have to this complicated. In the process, I released brand new CPAN distribution: DBIx::Class::Schema::GraphQL.
8 Jun
In this post, I shared how to integrate DBIx::Class with GraphQL. Having played with GraphQL, I can say it is not for weak heart. If you are coming from REST API background then it will take some time to get your head around it. I am telling this from my …

The post is meant for beginners as I am exploring GraphQL for the first time as well. The best part is the use of GraphiQL for building and testing the API.

After dealing with gRPC, next in line was JSON-RPC. The motivation was to explore MCP after getting to know JSON-RPC. It turned out to be too easy demonstrate.
8 Jun
First time managed to build a debian package for DBIx::Class::Async with step by step instructions.

In this post, I try to decode what RAG is and how we can implement RAG engine in Perl talking to LLM and Vector database in a docker container.
Continue with the series post on DBIx::Class, in this post I am showing the power of DBIC components dealing with date/timestamp column.
