Alexander Kiryuhin has been very busy in the past week. Not only did they release a Comma Complete update (the Raku IDE of choice, now with 2020.02 IntelliJ support). They also released the Rakudo 2020.09 Compiler Release implementing the Raku Programming Language. And Claudio Ramirez made sure there are ready to download Linux packages for that release. And Timo Paulssen made sure there’s an AppImage for it as well!
A Raku Manifesto
After asking a pretty pertinent question on Reddit, Daniel Sockwell continued to produce high-quality thought provoking blog posts. This time, it’s part 1 of a Raku Manifesto, describing what they think the Raku Programming Language is about. Thinking about expressive code vs uniform code, rewarding mastery vs ease of learnability, powerful vs unsurprising code and finally, individual vs large-group productivity. A must read for each Rakoon (/r/rakulang comments)!
Timo Paulssen was unsatisfied by the installation process of MoarPerf (the full Rakudo profiler for MoarVM). Until they found out about AppImage, a format for Linux that allows programs to be distributed as a single executable file. Then packaged MoarPerf and Rakudo in it, and also blogged about it. Can you AppImageine that?
A Universal Interpreter
Wim Vanderbauwhede continues their journey into functional programming with Raku, with two instalments (Twitter comments):
- Encoding types as functions about implementing algebraic data types using roles.
- A universal interpreter with a demonstration using a parsed polynomial expression.
Another round of grant requests
Only a few more days to go to submit your grant proposals to improve the Raku Programming Language for the September 2020 round!

Wenzel P.P. Peppmeyer only wrote one blog post this week: List breaks the chain.
Yet another Pearl
Andrew Shitov wrote another episode in the Pearls of Raku series this week. Issue 13: functional elements and recursive sum.
Weekly Challenge #80 is available for your perusal. And Andrew Shitov did a full review of the Raku solutions of Challenge #78 (including a video run-through).
Most of the core developments have been happening in the new-disp (resume on dispatch related work) and rakuast branches (converting RakuAST trees back to Raku source code, AKA deparsing). Meanwhile, in the main branch:
- Patrick Böker fixed an issue with the
-xwhen running as root and fixed some
NQPbuild dependency issues.
- Nicholas Clark added support for the
Sparc64architecture to MoarVM and fixed a bug in hash resizing.
- Daniel Green improved the performance of the
Int.is-primemethod: 355x as fast for prime numbers below 2_000_000_000, and down to “only” 2.5x as fast for prime numbers above 10_000_000_000.
- Christian Bartolomäus changed the internal handling of
JVMbackend and worked on unifying Unicode decoder tests on all backends.
- Elizabeth Mattijsen made sure that the
X::Method::Notfoundobject does not do work on creating suggestions unless that is really necessary, thereby fixing a regression in the
- And some other smaller fixes and improvements.
