2021.10 Automated Star

Patrick Spek has announced the release of the Rakudo Star 2021.02.1 package (based on the 2021.02.1 Rakudo Compiler release). This is the first time this has happened using a Github Action workflow. Binary releases are not yet available: like everything in the Raku Programming Language, it is the work of volunteers. To create MacOS and Windows installable packages, a volunteer is needed to create the Github Actions workflow for MacOS and/or Windows! The advantage being that this way, you would only need to do this once instead of for each release! So please, stand up if you have the know-how and time to do it!

February Grant Report

Jonathan Worthington has published their February Grant Report for the RakuAST Grant (/r/rakulang comments).

Thread safe caching

Simon Proctor blogged about a thread safe caching algorithm in the Raku Programming Language, which resulted in quite a discussion on the pros and cons of the various approaches in /r/rakulang.

Through the cracks

It appears yours truly missed the announcement of an interesting application written in Raku last August: Hubtodate by demostanis (/r/rakulang comments). Kudos and apologies to demostanis.


Weekly Challenge #103 is available for your perusal. Mohammad S Anwar also published a Monthly Report.

Core Developments

  • Ben Davies reworked basic socket handling in MoarVM (which will percolate to NQP and Rakudo in the coming weeks), improved serialization of C types in MoarVM and fixed problems with the JavaScript backend script runner.
  • Leon Timmermans added a Callable parameter to Lock.wait to indicate when it should stop waiting, and made sure the setting uses that where possible (which should reduce the number of locks taken considerably in some situations).
  • Elizabeth Mattijsen made sorting upto 2x as fast by working around an issue of boolification of enums, and made nodemap / deepmap about 2x as fast (which affects >>. hypering in a similar way).
  • Daniel Sockwell made cmp on Nums about 2x as fast.
  • And some other fixes and improvements to internal documentation.
  • Plus some work on the RakuAST branch by Jonathan Worthington and Elizabeth Mattijsen.
