Alexey Melezhik has returned to the Raku Realm with a new tool, called R3 (the Rakudo Releases Readiness Tool). The idea being that bug reports should have an easy way to check whether the bug still exists or not, using a one-liner. Alexey explains in a blog post: Baking Rakudo Releases With R3 (/r/rakulang comments). Yours truly hasn’t had the time yet to really try it, but it looks like it’s going to be a great helper for the core developers!

Vadim’s Corner

Vadim Belman explains why a remark about parameterizing roles with named arguments in the Roles or When One is Many article may have been technically correct, but that an underlying issue still would not make it work as expected: An Error In The Roles Article (/r/rakulang comments).

Wenzel’s Corner

Wenzel P.P. Peppmeyer was on a roll again this week with 2 blog posts:

• Being pragmat-ish
• Typed filters

In related news, a two-way bridge to Discord has been set up for the #raku IRC channel on Libera.Chat.

Flavio’s Corner

Flavio Poletti has started blogging about their experiences with the Raku Programming Language. The past week saw 3 blog posts!

• Default member values
• cglib – a priority queue (/r/rakulang comments)
• Another puzzle in Raku

esLibre over

The esLibre conference is over, and the Raku DevRoom was a success! JJ Merelo tweeted while the devroom was running:

• On Vue.js and Raku
• Easy to create a small backend with Cro
• On air!
• Great Internet duct tape!
• Malware Analysis
• Slides shared
• Useful running experiments
• The meaning of sigils
• The lookitupper
• Creating native binders
• Parsers for breakfast
• It’s a wrap!

Videos should be available by next week. So please check again!

The Raku Conference

It’s less than 6 weeks now until The Raku Conference, the first ever conference entirely dedicated to the Raku Programming Language, and the program is solidifying with announcements of 4 more presentations:

• A Raku API to Raku programs – the journey so far by Jonathan Worthington.
• A new general dispatch mechanism to speed up various slow Raku constructs by Jonathan Worthington.
• Sigils. Once you know them, you’ll love them in the Raku Programming Language by Elizabeth Mattijsen.
• The Weekly Pearls of Raku by Andrew Shitov.

And it looks like Mohammad S Anwar may be giving a presentation as well!

Weeklies

Weekly Challenge #119 is available for your perusal. And this week’s “What’s everyone working on (2021.26)” as well.

Pull Requests

• Fix unimatch for non-base properties
• Support (nearly) all HTML5 entities in Pod E<>
• Enable rendering of nested blocks in Pod::To::Text
• Add modf to the Raku core’s numerical routines

Please check these Pull Requests and leave any comments that you may have!

Core Developments

• Vadim Belman fixed a race condition with iterators and hypering.
• Daniel Sockwell fixed unimatch on Unicode non-base properties.
• Elizabeth Mattijsen made $() work properly (as in returning a container), added support for last taking a value, and exiting the REPL by pressing CTRL-c twice.
• And some other smaller fixes and improvements.

Meanwhile, Jonathan Worthington has gotten to the point where the new dispatch system has actually become the default for method dispatch (on the new-disp branch).

Winding down

Again with a little delay, this week’s Rakudo Weekly News is again a nice testament to the people blogging about the Raku Programming Language. Even though restrictions appear to be lifted in many places in the world, please remain vigilant to stay healthy and still have a good time: this isn’t over yet! In any case, hope to see you all next week again!
