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 …
8 Jun
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.
This week we were back to full strength. We have now dealt with all of the belated issues and all of the blockers. Paul will be shipping 5.43.11 very shortly. With the amount of changes we have had to merge, we will not be able to rush the .11 cycle, but …

Hi there,
Recently, I came across an article, The Day I Decided Never to Learn Python by Randal L. Schwartz. Well, Randal doesn't need an introduction. He took us back to 2001, the same era when

This is an excellent example of a bilingual coding approach. It contrasts high-level data structures in Python with Perl's more flexible but lower-level data manipulation. Simon offers a clear explanation of the two different languages used to explain how…
1 Jun
Roger produced a very thorough, well-organised explanation of the problem, using techniques such as hash frequencies and sliding windows to create solutions that are both clean and accurate. By comparing the two different languages Perl and Scala, Roger s…
This post presents an incredibly complete and conversational analysis of the obstacles, illustrated with sophisticated technical knowledge through a thoroughly well-organised, educational format. Robbie's skill at blending solid, production-level Perl cod…
This blog post exemplifies well-designed code that solves the "Find K-Beauty" problem in a strong manner. Reinier does an excellent job of providing clear, modular logic and using the least amount of code to implement those solutions. This allows the read…
A clear and systematically organised method for resolving this issue is provided within this post, as well as a very easy to read content style, making it simple to see the reasoning behind the solution. Among other things, this post displays a good prese…
1 Jun
This solution exemplifies how effective algorithms can be designed, using math formulas as a way of running multiple sets of frequencies over a single array. It’s an example of a very concise method of solving complex state-tracking issues, using the leas…
Packy has created an outstanding multi-language deep dive post comparing different implementations of Raku, Perl, Python, and Elixir. In addition to providing many details about each language's implementation, his approach is to focus on making it easy to…
1 Jun
This is an exemplary work featuring high-quality code that has a high degree of maintainability, uses excellent error check techniques and provides high levels of readability. In addition to using excellent reading technique, his solutions include well-do…
This post shows a clear-cut way to address a problem and demonstrate a solid grasp of Perl's function-based capabilities. It uses expressive one-line Perl statements to demonstrate how small, readable, and consistent code can be written to transform data.
1 Jun
This blog post does a great job of examining and comparing the practical solutions using Perl and an advanced version of programming with the J language. The way Jorg has generalised the different types of problems he presented creates a sophisticated sol…
It provides an excellent, straightforward exhibition on how to solve the problems associated with Weekly Challenge 375 in Raku and Perl. In addition to showing off some of the more sophisticated, expressive data types that Raku supports (i.e., Bag) Jaldha…
1 Jun
This is an excellent example of how to use Raku's idiomatic style to perform frequency analysis with a very elegant way of using Bag data type and to make use of the %% operator for nice clean checks of divisibility by using Raku's built in primitives ins…
Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Single Common Word" and "Find K-Beauty" 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 "Chessboard Squares" and "Doubled 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.

Oh, the evil eval.
The site already exposes information through a traditional web interface and a JSON API. But those interfaces were designed for humans and developers respectively. MCP gives AI systems a much cleaner integration point.

Toby Inkster created a programming language which blends a fairly JavaScript-like syntax with fairly Perl-like semantics, and a few other features that he hasn't really seen in many programming languages.
Hi there!
I try to keep track of the Perl-related events. You can find them listed at the bottom of each edition of the newsletter and on the events page on the Perl Weekly web site. There you can also find a link to embed the calendar in your c

The post explains the need to clearly specify the task requirements for the "Largest Same-digit Number" challenge. It shows that an ambiguous requirement has caused different solutions to develop and serves to remind us that "coding to the examples" can b…

The post show how to solve problems using both Rust and Perl languages. It also demonstrates how one can take advantage of the strengths of each language (type-safe collections in Rust vs concise string searches in Perl) to carry out the tasks, but do so …
In this post, you'll find a brief yet highly efficient method of solving the "Largest Same-digits Number" challenge. The method relies on a single-pass regular expression as an elegant means to perform pattern matching with maximum effectiveness, and exem…
This post takes an insightful and interesting view of the vowel-counting challenge by making an interesting analogy of programming logic and music theory from the 18th century. The "Prefix/Cell/Suffix" model is a unique and clear technical explanation of …
25 May
Peter provides a well-reasoned and pragmatic assessment of the problem at hand and presents readable, non-complex code. He broke up all vowel characters in the string into separate chunks prior to applying a sub-substring check which provides an excellent…

This post showcases some great, multi-lingual solutions to this week's challenge by providing clean and idiomatic code examples in Perl, Raku, Python, and Elixir. Packy explains the thought process and the differences between lookaheads in regular express…
25 May
This fantastic example on how to reduce large scale problems into highly efficient solutions using half-lines of codes, showcases Perl’s ability to allow us to write complex, yet very succinct, solutions of difficult problems. It also serves as a great ex…
25 May
The code provided is a highly legible and clear way of handling the challenge resolution process, making use of commonly used data structures to simplify complex string processing tasks. It is very pleasing to see this clean, parallelised logic presented …
25 May
The post demonstrates an extremely sophisticated work to the challenge. It uses advanced Perl's regex features, look-ahead assertions and the (?{...}) code block.
25 May
This is an excellent post describing a different way of using Raku. It demonstrates the effectiveness of Raku by utilising such features as 'gather/take' and powerful sequence grouping to make complex string processing simpler than ever before. In additio…

I noticed the mention of optional chaining PPC in the report. If it is what I think it is then I am super happy that it is in safe hand now. I can't wait to see the end result. Thank you Paul.
