Oleksandr Kyriukhin announced a new version of the Comma Complete IDE for subscribers, with a new impressive real-time overview of every open file, socket, process, thread plotted on a timeline. And other assorted fixes and updates, of course!

Conference Program

The Perl & Raku Conference will be in Houston from June 21 to June 25. These are the Raku presentations:

• Raku -Ofun for Everyone by Daniel Sockwell.
• Raku for Beginners by Bruce Gray.
• raku::Dan – Re-Inventing the DataFrame by Steve Roe.
• Make a module for you and others: creation and submission to Fez by Matthew Stuckwisch.
• Grammatical (dis)agreement: Mixing grammars in Raku by Matthew Stuckwisch.
• Three ways to Make Wrong Code Look Wrong(er) by Daniel Sockwell.
• Code intelligence for any editor by b_scan.
• Playing nice with others using the new COERCE protocol by Matthew Stuckwisch.
• Raku Documentation Working Group by Daniel Sockwell.

And there will also be Hackathons for people interested in Raku development!

Anton’s Corner

Anton Antonov has published a Bulgarian version of Introduction to data wrangling with Raku (/r/rakulang comments), as well as a new (English) blog post about the detection of outliers in a list of numbers (/r/rakulang comments).

Wenzel’s Corner

Wenzel P.P. Peppmeyer has written a blog post about looking for hexadecimal words and distinct directories (using sets) and notes that Raku will make keyboards last twice as long.

Steve’s Corner

Steve Roe wrote a blog post about their research of calling Rust libraries from Raku in Raku & Rust: a romance? (/r/rakulang comments).

my @a = <a b c d>;
say @a.pairs; # (0 => a 1 => b 2 => c)

But maybe the .antipairs method is more useful tool, for instance to turn an array into a hash lookup:

say @a.antipairs; # (a => 0 b => 1 c => 2)
my %lookup = @a.antipairs;
say %lookup<b>; # 1

Weeklies

Weekly Challenge #167 is available for your perusal.

Winding down

Sadly our release manager Justin DeVuyst was flooded in $work, so the 2022.05 release has been delayed a week. The movement of Raku community modules from the git ecosystem to the zef ecosystem is still progressing nicely. And three new modules with exciting functionalities!

This week’s image was created using an XBeam GyroTwister. The Rakudo Weekly News will continue to show Ukrainian inspired images in support of Ukrainian people, and any other people who are trying to make an end to the Russian aggression in Ukraine. Слава Україні!  Героям слава!

In the mean time, please stay safe, stay healthy, keep up the good work!
