2025.23/24 Vibe codified

It looks like AI has reached Raku: in the article Let’s Teach An LLM To Write A New Programming Language Matt of the Nurture the Vibe website shows how an LLM can be created to write programs in the Raku Programming Language. The flood of new modules this week shows that at least one person was paying attention.

Fernando’s Corner

Fernando Correa de Oliveira blogged about Deps, a minimalist Raku module for exploring dependency injection patterns through a clear, trait-based API (/r/rakulang comments).

Anton’s Corner

Anton Antonov published part 2 and 3 of the LLM Function calling workflows series:

Steve’s Corner

Steve Roe has published another HARC Stack blog post, this time about setting up a Hamburgers menu, and how Air makes life easy for the HARC Stack website developer!

Ralph’s Corner

A gist that Ralph Mellor posted a few years ago about Raku’s metamodel called “Raku’s core” got quite a lot of attention on the interwebs the past week: on lobste.rs, on /r/programming.

Herbert’s Corner

The video of Herbert Breunung‘s presentation at the German Workshop called “Raku Quiz” has been published (German spoken).

Weeklies

Weekly Challenge #325 and #326 are available for your perusal.

New Pull Requests

Core Developments

  • Geoffrey Broadwell continued cleaning up the Unicode UCD download logic in MoarVM in preparation for future Unicode updates.
  • Timo Paulssen improved some (error) messages in MoarVM, improved memory usage of slurp() for small files, and made nqp::normalizecodes be more memory efficient.
  • Leon Timmermans made MoarVM CI stop using the Windows 2019 runner, as it will no longer be supported in the near future.
  • Patrick Böker merged all of the work of the past months on new runner wrappings for scripts installed with modules.
  • ivanyoung10 added well appreciated comments to some of the sanity tests.
  • Will Coleda has been busy with many documentation (web-site) related issues.

In RakuAST developments in the past 2 weeks:

  • Daniel Green removed a lot of unneeded uses of IMPL-WRAP-LIST, and, together with Stefan Seifert, fixed a really pesky issue with EVAL at BEGIN-time.
  • Almost all of the work on the “bootstrap” branch of the past months (mostly done by Stefan Seifert) was merged into the “main” branch.
  • Elizabeth Mattijsen introduced the $?CHECKSUM (a checksum of the source) and $?SOURCE compiler variables (the actual source from which the bytecode of the compilation unit was compiled), fixed an issue with --rakudoc, made the environment variable RAKU_LANG_VERSION actually work, and fixed several issues that would have showed up if the default language version would be 6.e.
  • Stefan Seifert fixed an issue with multiple tag passing in a use statement.

New Raku Modules by Danslav Slavenskoj

About a week ago, a large number of new modules authored by Danslav Slavenskoj started appearing completely out of the blue. The sheer magnitude of new modules (about 3 per day), as well as the size of the code and documentation produced, points to the use of AI in the creation of these modules.

  • Text::Lorem “Generate Lorem Ipsum placeholder text”.
  • Math::BijectiveBase “Bijective base encoding (spreadsheet column numbering)”.

Updated Raku Modules

Winding down

Thank you all for your patience! The second Raku Core Summit was a packed long weekend of discussions and hacking, about which some blog posts will appear in the coming week(s). Please stay tuned!

Please keep staying safe and healthy, and keep up the good work! Even after week 20/21 of hopefully only 209.

Meanwhile, still: Слава Україні!  Героям слава!
