The Elephant in the Room

At the Conference in the Cloud, Sawyer X (the Perl pumpkin) dropped a bit of a bombshell when they announced Perl 7 (skip to the part where they go into Perl’s relation to Raku). This caused quite bit of reactions, news articles, blog posts and discussions. These are the ones that relate to Raku:

• /r/rakulang, /r/perl, Hacker News comments.
• On Perl 7 by Andrew Shitov.
• perl7 vs. raku: Sibling Rivalry? by Stephen Roe (/r/rakulang, Twitter 1 2 comments).
• Announcement on perl.com by brian d foy.
• Statement by The Perl Foundation (no mention of Raku)
• Michael Tsai, LWN.net, Lobsters, Slashdot, Gigazine, ABC Linuxu (Czech), Developpez.com (French), Heise (German), root.cz (Czech), Ferramentas Linux (Portuguese), golem.de (German), LinuxEden (Chinese), SDTimes, Linux Magazin (German), TheNewStack, ZDNet, ZDNet Japan (Japanese), Soylent News
• FaceBook, Twitter

Itertools reprised

Tyler Limkemann continued their blogging, this time about Python’s itertools in pure Raku. This incited quite a few comments on /r/rakulang. Which inspired a follow-up blog post: Explaining Raku using Python’s itertools (/r/rakulang comments).

Prodigals returning

After a long absence, John Haltiwanger has returned with a blog post on how they used Raku to thwart the system in Raku to the Rescue: APL Keyboard Setting Keeper (/r/rakulang comments).

Joshua Yeshouroun has also returned with a small blog post: Pick and Choose (Part N), announcing the first upload of their Math::Combinatorics module.

Mark Carter returns with a blog post about An assembler for a virtual machine (/r/rakulang comments).

Perl, Haskell & Raku

Wim Vanderbauwheide continues their blogging with an extensive blog about List-based parser combinators in Haskell and Raku (/r/rakulang comments), which basically requires having read their previous blog post about Roles as Algebraic Data Types. Recommended!

Yet Another Two Still

Wenzel P. P. Peppmeyer continues to publish 2 blog posts a week, each addressing some feature or quirk of the Raku Programming Language.

• A Raku riddle
• We can do more

Weekly Challenge

The entries for Challenge #66 that have Raku solutions:

• Mangling integers by Luca Ferrari.
• Dividing Powers with Raku by Arne Sommer.
• Weekly Challenge #66 by Javier Luque.
• Weekly Challenge #66 by Shahed Nooshmand.
• Weekly Challenge #66 by Mohammad S Anwar (videos task #1, task #2).

• Weekly Challenge #66 by Jaldhar H. Vyas.

Andrew Shitov provided an overview of their solutions to previous challenges. And the next Challenge #67 is up for your perusal!

Core Developments

Most of the work of the past week has been done behind the scenes in branches: Stefan Seifert worked on in-process pre-compilation, Jonathan Worthington and Timo Paulssen worked on the new dispatch mechanism, Elizabeth Mattijsen worked on a refactoring of the way Match objects are populated.

• Daniel Green added support for JITting return_i / return_s / return_ n.
• Nicholas Clark fixed some issues with Unicode in MoarVM that we didn’t know we had.
• And some other fixes, optimisations, and improvements.
