After last weeks part 1 of a Raku Manifesto, Daniel Sockwell continued with part 2 of a Raku Manifesto, handling matters such as valuing individual productivity over large-group productivity, without devaluing large-group productivity. Again, a must read for each Rakoon (/r/rakulang comments). Can’t wait to read part 3!

Typing Junctionally

Wim Vanderbauwhede continues their journey into the Raku Programming Language, with two instalments focusing on Junctions:

• The strange case of the greedy junction
• Reconstructing Raku’s junctions

A Grant Proposal

Piotr Fusik has submitted a grant proposal for a Ć-to-Raku translator. Ć is a programming language which can already be translated automatically to C, C++, C#, Java, JavaScript, Python, Swift and OpenCL. If you have any thoughts about this proposal, be sure to leave them with the proposal!

A bouquet of blog posts

This week saw a rather large set of blog posts about the Raku Programming Language from various expected and unexpected corners of the Earth:

• Sharing command line parameters using proto by JJ Atria.
• Sparrowhub.io – repository of devops and automation utilities by Alexey Melezhik.
• Releasing for virtuous programmers by Wenzel P.P. Peppmeyer.
• Machine Math and Raku by p6steve (/r/rakulang comments).
• The Or Junction (Chinese) by Kang-min Liu.

Weekly Challenge

Weekly Challenge #81 is available for your perusal. And Andrew Shitov did a full review of the Raku solutions of Challenge #79 (including a video run-through), and Simon Proctor looked back on that.

Core Developments

Most of the core developments have been happening in the rakuast branch (converting RakuAST trees back to Raku source code, AKA deparsing). Meanwhile, in the main branch:

• Daniel Green fixed a race-condition in multi-threaded precompilation.
• Stefan Seifert fixed a bug in multi-part declarations of packages.
• Perry Thompson added a workaround to make $*USER and $*GROUP work correctly on non-POSIX locales.
• And some other smaller fixes and improvements.

This week’s new Pull Requests:

• Minor optimization of MVM_file_isexecutable on Windows
• Update MoarVM to Unicode 13.0, 13.1
• Improve streaming decoder on the JVM backend
• Binary release pipeline fixes
• Build: A wrong NQP version should abort the build
• Update tests for Unicode 13.0, 13.1
• Add Junction.collapse method

Please check them out and leave any comments that you may have!

Winding down

A much quieter week, but with still some thought provoking blog posts!

In another language, in another galaxy, Tau Station (a digital expression of love between a beautifully written science fiction novel and a grippingly immersive MMO RPG) has started a Kickstarter to help it improve and expand their horizons. Knowing that many Rakoons are science-fiction fans as well, yours truly thought it would appropriate to draw your attention to this :-).

Please don’t forget to stay healthy and to stay safe. Until next week for more news about the Raku Programming Language. Until then!
