2019.34 A Quick One From The Atlantic

While the ferry is slowly exiting the Cherbourg harbour en route to Dublin (trying out an alternate route to Ireland from mainland Europe without having to enter the UK), yours truly found some time laying around in the lounge. And used that to write this week’s Perl 6 Weekly.

Videos of PerlCon in Riga

The Riga video team has created separate videos of the presentations at PerlCon in Riga. These are the Perl 6 ones:

• Welcome word by Larry Wall.
• Perl 6 performance update by Jonathan Worthington.
• Perl 6 for beginners by Jens Rehsack.
• Apocrypha: stories about Perl 6 documentation by JJ Merelo.
• Parsing confidently by Lars Dɪᴇᴄᴋᴏᴡ 迪拉斯.
• DeMythifying Perl 6 by Elizabeth Mattijsen.
• WebPerl – Run Perl in the Browser! by Hauke Dämpfling.
• Constraint Programming in Perl 6 by Laurent Rosenfeld.
• Console oriented sites and Perl 6: joining the worlds together by Igor Chubin.
• When Cro is not a Web Framework: implementing LDAP for Perl 6 by Alexander Kiryuhin.
• The parsed and the curious: macros for Perl 6 by Carl Mäsak (/r/perl6 comments).
• Perl 6 Concurrency by Jonathan Worthington.
• Genesis: Concurrent evolutionary algorithms in Perl 6 by JJ Merelo.
• Easy as Six by Arne Sommer.
• ASN.1 for Perl 6: with elegance and metacompilation by Alexander Kiryuhin.
• Dockerize your Perl 6 tests! by JJ Merelo.

See an overview of all videos in case you missed a presentation (/r/perl6, /r/perl comments).

GSOC Wrapup

Madeleine Goebel published the wrapup: Summer in Review of her GSoC Self Contained Executable Project. In it, she describes how you can now make an executable out of any user program that does not use modules, or uses a single module. Clearly, work is still needed to make this feature more generally applicable. But these are amazing steps forward (/r/perl6 comments)!

Complex builds

Sterling Hanenkamp elaborates about how he uses Build.pm to organize complex build issues for Perl 6 distributions.

KSyntaxHighlighting

Christoph Cullmann posted a blog about editor highlighting called
“KSyntaxHighlighting – Over 300 Highlightings…” (/r/perl6 comments).

Perl Weekly Challenge #22

Blog posts with Perl 6 solutions for Challenge #22:

• Sexy Primes, LZW and Perl 6 by Arne Sommer.
• Perl Weekly Challenge – 022 by Mark Senn.
• Perl Weekly Challenge: Week 22 by Jaldhar H. Vyas.
• Perl Weekly Challenge # 22: Sexy Prime Pairs and Compression Algorithm by Laurent Rosenfeld.
• Perl Weekly Challenge 22 by Roger Bell West.

Ruben Westerberg has been announced a Perl Weekly Champion. Also, Challenge #23 is up for your perusal (about which Aaron Sherman gives some pointers).

On renaming

Several people commented on the plan to rename Perl 6 to Raku:

• Consequences for Perl 6 after renaming by Aaron Sherman.
• Yet Another Renaming Discussion – I change my vote and suggest a shift in focus by bobthecimmerian.

Core Developments

• Bart Wiegmans saw his work on the JIT of the past 8 months, finally merged.
• ZhongnianTao saw his work on supporting the GB18030 encoding merged as well.
• Timo Paulssen fixed a problem with a repr mismatch with NativeCall.
• Daniel Green JITted some nqp::num functions.
• Deven T. Corzine saw his work on the execstack fix merged.
• Moritz Lenz fixed a problem in the expression template compiler.
• Christian Bartolomäus fixed some issues on the JVM backend, and Paweł Murias helped him while fixing some issues on the Javascript backend as well.
• Vadim Belman performed a lot of work on more easily supporting multiple language versions.
• And some smaller fixes and improvements.
