The first batch of Advent Calendar 2023 posts about the Raku Programming Language has arrived again!

• Day 1 – Rocking Raku Meets Stodgy Debian by Tom Browder (/r/rakulang comments).
• Day 2 – An update on raku.land by JJ Atria (/r/rakulang comments).
• Day 3 – Helping the Elves Sort Their Mail by Julia.
• Day 4 – Embedding a stack-based programming language in Raku by Wim Vanderbauwhede.

Kudos to Dominique

In a mail on the mailing-list, Dominique Dumont announces their stepping down from being the packager of Rakudo for the Debian distribution after 10 years! So a big Thank You! is in place for the many years that they have done this job. And if you’re reading this and want to have Rakudo properly packaged on Debian, please contact them for the “keys”!

Mike’s Corner

Mike Clarke describes how they took over the maintenance of the Readline module and made it work on MacOS, and then made it work on OpenBSD, meanwhile helping fix zef as well.

Weeklies

Weekly Challenge #246 is available for your perusal.

New Problem Solving Issues

• Unclear sharing of $/ causing race conditions
• Comma-separated ... “triple-dot” sequences (e.g. for array indexing) produce bizarre results.
• IO functions should have additional typed errors

New Pull Requests

• Attempt at adding debugging to delete-by-compiler to test https://git…
• Deprecate IO subs that operate on multiple paths in 6.e

Core Developments

• Elizabeth Mattijsen fixed the lines() subroutine not honouring the :chomp argument.
• Vadim Belman implemented almost full support for the instantiation of generics.

In RakuAST developments this week:

• Elizabeth Mattijsen fixed the semantics of the ? regex quantifier.
• The number of passing test-files with the new Raku grammar are now 111/150 (make test +0) and 981/1358 (make spectest +0).
