Perl Weekly=20
https://perlweekly.com/
You can read the newsletter on the web, if you prefer.
https://perlweekly.com/archive/769.html
Hi there,
Every week I see a post declaring about something being dead. Agile is
dead! Testing is dead!, Algol-68 is dead! I am so fed-up with this. So I am
not going to link to the article that was discussing 5 dead programming
languages.
Last week finally I got home and because of the flight I had to postpone
the Testing in Perl ( https://luma.com/perl-maven ) event so it will be
held this Thursday. You are invited to watch the previous sessions (
https://academy.code-maven.com/c/perl-testing-2026 ) (for now free of
charge) and join the next one.
The Perl Maven WhatsApp group (
https://chat.whatsapp.com/LRrkZsSRDvGLLwppyLnKHy ) already has more than 70
members. Unfortunately recently we got a few spammers so I had to turn on
registration-approval. This means that when you try to join I'll send you a
private message asking who you are. This is the little extra step we have
to do to avoid spam. Anyway, you are invited to join us!
Enjoy your week!

RECAP - The Weekly Challenge - 369
https://theweeklychallenge.org/blog/recap-challenge-369
=20
Enjoy a quick recap of last week's contributions by Team PWC dealing with
the "Valid Tag" and "Group Division" tasks in Perl and Raku. You will
find plenty of solutions to keep you busy.
--------------
=20
Perl Weekly Challenge 369: Valid Tag
https://abigail.github.io/HTML/Perl-Weekly-Challenge/week-369-1.html
=20
This post provides multiple amazing examples of technical versatility by
providing a clean and direct solution written clearly in many different
programming languages with tremendous flair, it shows great elegance in
presenting the elegant and simple solution to the valid tag problem using
the idiomatic language of each respective programming language. Abigail
shows off expert level code writing skills by using the advanced
character class arithmetic features present within Perl; these advanced
ways of manipulating strings show the efficiency of his coding style,
while simultaneously creating visually appealing code.
--------------
=20
Perl Weekly Challenge 369: Group Division
https://abigail.github.io/HTML/Perl-Weekly-Challenge/week-369-2.html
=20
This post offers an extremely polished and versatile engineering design f=
or
the island program project. Abigail has shown advanced expertise by using
a 'chunk-and-fill' method over many different programming languages
(Perl, C, and less common languages such as sed, including details on how
string slices and fill-up strings can be done with the least amount of
impact. Furthermore, it highlights a creative use of string replication
operators as well as very efficient use of loops that guarantee that the
final incomplete group will still have the correct amount of padding
added based on the requirements given in the challenge.
--------------
=20
Tag Division
https://raku-musings.com/tag-division.html
=20
In an idiomatic Raku implementation of the Group Division problem, as sho=
wn
pretty clearly here by Arne Sommer, the gather/take construct is utilised
nicely to collect the data clearly, and with the use of substr-rw for
in-place string manipulation and the replication operator (x) to add
padding, the solution is both easily readable and aesthetically pleasing.
--------------
=20
Perl Weekly Challenge: Week 369
https://www.braincells.com/perl/2026/04/perl_weekly_challenge_week_369.ht=
ml
=20
By taking advantage of mathematical precision and the crispness of concis=
e
syntax through the use of "one liners", Jaldhar has developed an
efficient method for solving this problem, no matter if you're using Raku
or Perl. Calculating the required amount of padding to add to a split
string before actually splitting it, allows for quick and accurate
results. Furthermore, the clever application of native string
manipulation functions adds an additional level of efficiency and clarity
to handling the grouping logic.
--------------
=20
Divided Tags
https://github.sommrey.de/the-bears-den/2026/04/17/ch-369.html
=20
This article offers a detailed examination of the many aspects of the
"Valid Tag" challenge and provides a well-defined "word" in order to
enhance the accuracy of processing. The body of this technical paper
describes Jorg's unique application of the Perl programming language's
ability to utilise global regular expressions (regex) to solve Task 2;
and also the excellent "Shape" verb from the J programming language that
has provided an efficient and generalised way to reshape and pad
multi-dimensional arrays.
--------------
=20
The Weekly Challenge 369
https://kolouch.net/perlweeklychallenge/blog-369.html
=20
In this post, we look at the approach both challenges in a disciplined an=
d
structured manner. The focus is on having code that is easy to maintain
and easy to read. We have examples showing clean, modular Perl and Python
code, and show examples of how the "Group Division" challenge is solved
using efficient use of list slicing and using generator expressions to
partition and pad strings in a method that's worthy of professional
quality.
--------------
=20
string indexes
https://fluca1978.github.io/2026/04/13/PerlWeeklyChallenge369.html
=20
Luca Ferrari exhibits an incredible degree of technical ability through h=
is
creation of five unique environments in which to accomplish the Week 369
challenges. Those five programming environments are: Raku, Python,
PostgreSQL (PL/Perl, PL/PgSQL, and PL/Java). Luca's elegant use of Raku's
rotor method combined with the ability of Python's list slicing to
achieve the same complex logic for string padding and partitioning, as
demonstrated in his application of The Group Division challenge, show how
many different programming languages can utilise very diverse methods to
accomplish the same technically precise logic.
--------------
=20
Perl Weekly Challenge 369
https://wlmb.github.io/2026/04/13/PWC369/
=20
The post demonstrates exceptional compact Perl programming by distilling
complex string processing procedures into "1.5-liners" that are quite
efficient. For Task 1, he builds camelCase tags from a string of input
values using the split, map, and join functions in order to achieve the
desired result in one pass. In addition, Luis's approach to Task 2 makes
use of a brilliant "alternation" regex (.{$size}|.+) as a means of
capturing both full and partial segments of an input string in an optimal
manner. The use of this regex allows him to create direct array-index
padding, resulting in code that is not only concise, but also very
technically accurate and well-balanced between the two principles.
--------------
=20
Good Tags and Good Chunks
https://github.com/MatthiasMuth/perlweeklychallenge-club/tree/muthm-369/c=
hallenge-369/matthias-muth#readme
=20
Matthias Muth has written an impressive article on internationalisation
(I18N) relating to pragmatic problem solving while still maintaining a
strong long-term support model through thoughtful design choices such as
those found within both the "Valid Tag" and "Group Division" solutions
provided by Matthias's book. The use of the Text::Unidecode module was
one way to create technically superior solutions that would accommodate
for the presence of non-ASCII character sets and would also adhere to the
rules specified in the challenge itself (e.g., valid tag). Additionally,
his solution for "Group Division" is equally amazing because he
accomplished this via a mathematical pad for the purpose of executing a
clean single regex global match - or a single line of functional code -
that could otherwise be accomplished via several iterations of code.
--------------
=20
Strings Will Tear Us Apart
https://packy.dardan.com/b/nR
=20
In this post, Packy gives a thorough, contemporary example of string
handling in Raku, Perl, Python, and Elixir. He creates a unique solution
to the "Group Division" challenge by using the Raku function .comb with
integer arguments to automatically divide into chunks and by using the
Perl 'unpack' function with a per-function constructed template,
demonstrating how you can creatively employ language idioms to
efficiently and effectively resolve a common programming issue and
provide a solution for data partitioning that uses little or minimal
resources.
--------------
=20
Fun with strings
http://ccgi.campbellsmiths.force9.co.uk/challenge/369
=20
In his article, Peter presents a practical and polished approach to
developing an order of operations for the sanitisation of strings. By
organising the procedure so that lower case, regular expression character
removal, and space & character combination are completed before the
creation of camelCase, the end product meets the requirements for both
camel case formatting as well as length requirements while still
producing clean, effective code.
--------------
=20
The Weekly Challenge - 369: Valid Tag
https://reiniermaliepaard.nl/pwc/index.php?id=3Dpwc369-1
=20
In Reinier's method, a model for defensive programming has been developed
that features validation of input for real alphabetic values before
processing. Also, he has taken a somewhat technical approach
(transforming input to remove non-letter characters by converting them to
spaces in order to apply camelCase correctly while keeping word
boundaries intact) through his use of multiple accurately readable
regular expressions.
--------------
=20
The Weekly Challenge - 369: Group Division
https://reiniermaliepaard.nl/pwc/index.php?id=3Dpwc369-2
=20
Reinier has created a very good tutorial solution which showcases how to
use the "Perl 4-argument substr function" to extract and remove data from
a string using a while loop to do so iteratively and then using string
replication for the final padding makes the code extremely readable and a
great technical example of using efficient in-place usage of strings.
--------------
=20
The Weekly Challenge #369
https://hatley-software.blogspot.com/2026/04/robbie-hatleys-solutions-in-=
perl-for_16.html
=20
The work done by Robbie within the "Valid Tag" review indicates a very we=
ll
thought out way to approach hyphenated compound words as a single entity
for case adjustment, in addition to providing an innovative solution for
"Group Division", by utilising the four-argument form of Perl's substr in
order to easily "chop and fill" strings, while also demonstrating his
superior knowledge of high-performance string manipulation.
--------------
=20
Divided Validity
https://blog.firedrake.org/archive/2026/04/The_Weekly_Challenge_369__Divi=
ded_Validity.html
=20
Roger's technical review offers an interesting side-by-side comparison of
various string handling paradigms from multiple programming languages.
The "Valid Tag" part of the review shows how Crystal's highly performant
state machine implementation allows for case conversion to be
accomplished in a single pass. The "Group Division" analysis of
in_groups_of() in Crystal is very interesting as well, as it illustrates
just how compact that library function is compared to typical iterative
slicing found in Typst, demonstrating that using built-in library
functions can greatly simplify the implementation of algorithmic logic
through less code complexity.
--------------
=20
Group Tag
https://dev.to/simongreennet/weekly-challenge-group-tag-k56
=20
A wonderful illustration of Test-driven development is Simon's critique o=
f
Challenge 369. He found through tests that the sanitisation step of
"Valid Tag", had to be completed before performing case formatting so
that example 5 is handled properly. He also provides useful technical
comparisons between both languages' ecosystem strengths, such as Python
using more_itertools.grouper vs Perl doing it manually by iteration.

You will<BR> find plenty of solutions to keep you busy.<BR> --------------<BR><BR> =20<BR> Perl Weekly Challenge 369: Valid Tag<BR> https://abigail.github.io/HTML/Perl-Weekly-Challenge/week-369-1.html<BR>=20<BR> This post provides multiple amazing examples of technical versatility by<BR> providing a clean and direct solution written clearly in many different<BR> programming languages with tremendous flair, it shows great elegance in<BR> presenting the elegant and simple solution to the valid tag problem using<BR> the idiomatic language of each respective programming language. Abigail<BR> shows off expert level code writing skills by using the advanced<BR> character class arithmetic features present within Perl; these advanced<BR> ways of manipulating strings show the efficiency of his coding style,<BR> while simultaneously creating visually appealing code.<BR> --------------<BR><BR> =20<BR> Perl Weekly Challenge 369: Group Division<BR> https://abigail.github.io/HTML/Perl-Weekly-Challenge/week-369-2.html<BR>=20<BR> This post offers an extremely polished and versatile engineering design f=<BR>or<BR> the island program project. Abigail has shown advanced expertise by using<BR> a 'chunk-and-fill' method over many different programming languages<BR> (Perl, C, and less common languages such as sed, including details on how<BR> string slices and fill-up strings can be done with the least amount of<BR> impact. Furthermore, it highlights a creative use of string replication<BR> operators as well as very efficient use of loops that guarantee that the<BR> final incomplete group will still have the correct amount of padding<BR> added based on the requirements given in the challenge.<BR> --------------<BR><BR> =20<BR> Tag Division<BR> https://raku-musings.com/tag-division.html<BR>=20<BR> In an idiomatic Raku implementation of the Group Division problem, as sho=<BR>wn<BR> pretty clearly here by Arne Sommer, the gather/take construct is utilised<BR> nicely to collect the data clearly, and with the use of substr-rw for<BR> in-place string manipulation and the replication operator (x) to add<BR> padding, the solution is both easily readable and aesthetically pleasing.<BR> --------------<BR><BR> =20<BR> Perl Weekly Challenge: Week 369<BR> https://www.braincells.com/perl/2026/04/perl_weekly_challenge_week_369.ht=<BR>ml<BR>=20<BR> By taking advantage of mathematical precision and the crispness of concis=<BR>e<BR> syntax through the use of "one liners", Jaldhar has developed an<BR> efficient method for solving this problem, no matter if you're using Raku<BR> or Perl. Calculating the required amount of padding to add to a split<BR> string before actually splitting it, allows for quick and accurate<BR> results. Furthermore, the clever application of native string<BR> manipulation functions adds an additional level of efficiency and clarity<BR> to handling the grouping logic.<BR> --------------<BR><BR> =20<BR> Divided Tags<BR> https://github.sommrey.de/the-bears-den/2026/04/17/ch-369.html<BR>=20<BR> This article offers a detailed examination of the many aspects of the<BR> "Valid Tag" challenge and provides a well-defined "word" in order to<BR> enhance the accuracy of processing. The body of this technical paper<BR> describes Jorg's unique application of the Perl programming language's<BR> ability to utilise global regular expressions (regex) to solve Task 2;<BR> and also the excellent "Shape" verb from the J programming language that<BR> has provided an efficient and generalised way to reshape and pad<BR> multi-dimensional arrays.<BR> --------------<BR><BR> =20<BR> The Weekly Challenge 369<BR> https://kolouch.net/perlweeklychallenge/blog-369.html<BR>=20<BR> In this post, we look at the approach both challenges in a disciplined an=<BR>d<BR> structured manner. The focus is on having code that is easy to maintain<BR> and easy to read. We have examples showing clean, modular Perl and Python<BR> code, and show examples of how the "Group Division" challenge is solved<BR> using efficient use of list slicing and using generator expressions to<BR> partition and pad strings in a method that's worthy of professional<BR> quality.<BR> --------------<BR><BR> =20<BR> string indexes<BR> https://fluca1978.github.io/2026/04/13/PerlWeeklyChallenge369.html<BR>=20<BR> Luca Ferrari exhibits an incredible degree of technical ability through h=<BR>is<BR> creation of five unique environments in which to accomplish the Week 369<BR> challenges. Those five programming environments are: Raku, Python,<BR> PostgreSQL (PL/Perl, PL/PgSQL, and PL/Java). Luca's elegant use of Raku's<BR> rotor method combined with the ability of Python's list slicing to<BR> achieve the same complex logic for string padding and partitioning, as<BR> demonstrated in his application of The Group Division challenge, show how<BR> many different programming languages can utilise very diverse methods to<BR> accomplish the same technically precise logic.<BR> --------------<BR><BR> =20<BR> Perl Weekly Challenge 369<BR> https://wlmb.github.io/2026/04/13/PWC369/<BR>=20<BR> The post demonstrates exceptional compact Perl programming by distilling<BR> complex string processing procedures into "1.5-liners" that are quite<BR> efficient. For Task 1, he builds camelCase tags from a string of input<BR> values using the split, map, and join functions in order to achieve the<BR> desired result in one pass. In addition, Luis's approach to Task 2 makes<BR> use of a brilliant "alternation" regex (.{$size}|.+) as a means of<BR> capturing both full and partial segments of an input string in an optimal<BR> manner. The use of this regex allows him to create direct array-index<BR> padding, resulting in code that is not only concise, but also very<BR> technically accurate and well-balanced between the two principles.<BR> --------------<BR><BR> =20<BR> Good Tags and Good Chunks<BR> https://github.com/MatthiasMuth/perlweeklychallenge-club/tree/muthm-369/c=<BR>hallenge-369/matthias-muth#readme<BR>=20<BR> Matthias Muth has written an impressive article on internationalisation<BR> (I18N) relating to pragmatic problem solving while still maintaining a<BR> strong long-term support model through thoughtful design choices such as<BR> those found within both the "Valid Tag" and "Group Division" solutions<BR> provided by Matthias's book. The use of the Text::Unidecode module was<BR> one way to create technically superior solutions that would accommodate<BR> for the presence of non-ASCII character sets and would also adhere to the<BR> rules specified in the challenge itself (e.g., valid tag). Additionally,<BR> his solution for "Group Division" is equally amazing because he<BR> accomplished this via a mathematical pad for the purpose of executing a<BR> clean single regex global match - or a single line of functional code -<BR> that could otherwise be accomplished via several iterations of code.<BR> --------------<BR><BR> =20<BR> Strings Will Tear Us Apart<BR> https://packy.dardan.com/b/nR<BR>=20<BR> In this post, Packy gives a thorough, contemporary example of string<BR> handling in Raku, Perl, Python, and Elixir. He creates a unique solution<BR> to the "Group Division" challenge by using the Raku function .comb with<BR> integer arguments to automatically divide into chunks and by using the<BR> Perl 'unpack' function with a per-function constructed template,<BR> demonstrating how you can creatively employ language idioms to<BR> efficiently and effectively resolve a common programming issue and<BR> provide a solution for data partitioning that uses little or minimal<BR> resources.<BR> --------------<BR><BR> =20<BR> Fun with strings<BR> http://ccgi.campbellsmiths.force9.co.uk/challenge/369<BR>=20<BR> In his article, Peter presents a practical and polished approach to<BR> developing an order of operations for the sanitisation of strings. By<BR> organising the procedure so that lower case, regular expression character<BR> removal, and space & character combination are completed before the<BR> creation of camelCase, the end product meets the requirements for both<BR> camel case formatting as well as length requirements while still<BR> producing clean, effective code.<BR> --------------<BR><BR> =20<BR> The Weekly Challenge - 369: Valid Tag<BR> https://reiniermaliepaard.nl/pwc/index.php?id=3Dpwc369-1<BR>=20<BR> In Reinier's method, a model for defensive programming has been developed<BR> that features validation of input for real alphabetic values before<BR> processing. Also, he has taken a somewhat technical approach<BR> (transforming input to remove non-letter characters by converting them to<BR> spaces in order to apply camelCase correctly while keeping word<BR> boundaries intact) through his use of multiple accurately readable<BR> regular expressions.<BR> --------------<BR><BR> =20<BR> The Weekly Challenge - 369: Group Division<BR> https://reiniermaliepaard.nl/pwc/index.php?id=3Dpwc369-2<BR>=20<BR> Reinier has created a very good tutorial solution which showcases how to<BR> use the "Perl 4-argument substr function" to extract and remove data from<BR> a string using a while loop to do so iteratively and then using string<BR> replication for the final padding makes the code extremely readable and a<BR> great technical example of using efficient in-place usage of strings.<BR> --------------<BR><BR> =20<BR> The Weekly Challenge #369<BR> https://hatley-software.blogspot.com/2026/04/robbie-hatleys-solutions-in-=<BR>perl-for_16.html<BR>=20<BR> The work done by Robbie within the "Valid Tag" review indicates a very we=<BR>ll<BR> thought out way to approach hyphenated compound words as a single entity<BR> for case adjustment, in addition to providing an innovative solution for<BR> "Group Division", by utilising the four-argument form of Perl's substr in<BR> order to easily "chop and fill" strings, while also demonstrating his<BR> superior knowledge of high-performance string manipulation.<BR> --------------<BR><BR> =20<BR> Divided Validity<BR> https://blog.firedrake.org/archive/2026/04/The_Weekly_Challenge_369__Divi=<BR>ded_Validity.html<BR>=20<BR> Roger's technical review offers an interesting side-by-side comparison of<BR> various string handling paradigms from multiple programming languages.<BR> The "Valid Tag" part of the review shows how Crystal's highly performant<BR> state machine implementation allows for case conversion to be<BR> accomplished in a single pass. The "Group Division" analysis of<BR> in_groups_of() in Crystal is very interesting as well, as it illustrates<BR> just how compact that library function is compared to typical iterative<BR> slicing found in Typst, demonstrating that using built-in library<BR> functions can greatly simplify the implementation of algorithmic logic<BR> through less code complexity.<BR> --------------<BR><BR> =20<BR> Group Tag<BR> https://dev.to/simongreennet/weekly-challenge-group-tag-k56<BR>=20<BR> A wonderful illustration of Test-driven development is Simon's critique o=<BR>f<BR> Challenge 369. He found through tests that the sanitisation step of<BR> "Valid Tag", had to be completed before performing case formatting so<BR> that example 5 is handled properly. He also provides useful technical<BR> comparisons between both languages' ecosystem strengths, such as Python<BR> using more_itertools.grouper vs Perl doing it manually by iteration.<BR> --------------<BR><BR> =20<BR><BR>=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D<BR><BR>Weekly collections<BR><BR> =20<BR> NICEPERL's lists<BR> http://niceperl.blogspot.com/<BR>=20<BR> Great CPAN modules released last week (<BR> https://niceperl.blogspot.com/2026/04/dxcvi-9-great-cpan-modules-released<BR> .html ).<BR> --------------<BR><BR> =20<BR><BR>=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D<BR><BR>Events<BR><BR> =20<BR> Perl Maven online: Testing in Perl - part 4<BR> https://luma.com/perl-maven<BR>=20<BR> April 23, 2026<BR> --------------<BR><BR> =20<BR> Perl Toolchain Summit 2026<BR> https://www.perl.com/article/announcing-the-perl-toolchain-summit-2026/<BR>=20<BR> April 23-26, 2026<BR> --------------<BR><BR> =20<BR> Boston Perl Mongers virtual monthly<BR> https://boston.pm.org/<BR>=20<BR> May 12, 2026<BR> --------------<BR><BR> =20<BR> The Perl and Raku Conference 2026<BR> https://tprc.us/tprc-2026-gsp/<BR>=20<BR> June 26-29, 2026, Greenville, SC, USA<BR> --------------<BR><BR> =20<BR><BR>=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D<BR><BR><BR><BR><BR>You joined the Perl Weekly to get weekly e-mails about the Perl programming=<BR> language and related topics.<BR><BR>Want to see more?
