Justin DeVuyst has released the 2023.10 release of the Rakudo Compiler implementing the Raku Programming Language. Followed up by the usual binary releases, and a new Rakudo Star release! Only a few visible changes this month, most of the work was done on RakuAST.

Weeklies

Weekly Challenge #240 is available for your perusal.

New Problem Solving Issues

• Mixing of weak typing and duck-typing is still prevalent for certain operators

New Pull Requests

• Add ｢…｣, ‘…’, and “…” as Regex syntax
• Add syscall that returns stat times in nanoseconds
• Allow a value of 0 with :vent-at
• Remove undocumented quotelang extenders
• Hungarian localisation of core
• Use new stat-time-nanos syscall

Core Developments

• Christian Bartolomäus has been quite busy on the JVM backend: implemented shared/non-blocking file locking, fixed a type checking issue between roles and classes, and fixed an issue with backtraces.
• Bernhard M. Wiedemann fixed an issue with reproducible builds.
• Daniel Sockwell made sure that the default .WHY message only refers to core types in the documentation.
• Nick Logan fixed an issue with the Distribution.content method and simplified installed raku scripts.
• Vadim Belman fixed the handling of dynamic containers on 6.e PseudoStash objects.

In RakuAST developments this week:

• Elizabeth Mattijsen continued working on localization features (such as localization of pragmas, quote-lang markers and internal regex modifiers).
• Ab5tract fixed an issue with re-declaration of $_, and binding of $_ on the right hand side of a smartmatch.
• Lucien Grondin added a French localization.
• The number of passing test-files with the new Raku grammar are now 110/149 (make test +0) and 975/1358 (make spectest +0).

Winding down

Quite a lot of work done while many regulars are getting more and more nervous about their presentation for the conference. Meanwhile, Слава Україні!  Героям слава!

Please keep staying safe and healthy, and keep up the good work!

If you like what I’m doing, committing to a small sponsorship would mean a great deal!
