2019.13 No Jokes Today

Rakudo Star Release 2019.03

Naoum Hankache has announced the release of Rakudo Star 2019.03, the first Rakudo Star release to feature support for Perl 6.d. Thanks to Naoum Hankache and his team in getting this brave new release out of the door. And kudos to Steve Mynott for having done a Rakudo Star release so many times before!

Perl Weekly Challenge Fallout

The first Perl Weekly Challenge generated quite some blog posts and tweets. Here’s a selection that (also) mention Perl 6 solutions:

• Long story about short answers to Perl Weekly Challenge no. 1 by Jo Christian Oterhals (Reddit comments).
• Perl Weekly Challenge Further thoughts by Simon Proctor (Reddit comments).

A second challenge has been published already! More Perl 6 solutions will be very welcome!

Zef plugins

Tony O’Dell introduces his work on creating zef plugins with an example of implementing a config parameter for zef for configuration management. This looks like some good ideas of git plugins have been assimilated!

I like Rakudo 100x

Wenzel P. P. Peppmeyer found a strange regression in Perl 6 and blogged about it. Which resulted in a Travis-CI test that should turn green whenever the bug gets fixed.

Staying composed

Paul Cochrane was frustrated about not being able to enter π on his keyboard, researched it and blogged about it extensively (Reddit comments).

Conditional whenever

Wenzel P. P. Peppmeyer actually wrote a second blogpost this week, this time about filtering the output of iostat, which uses a Supply that does nothing. I guess that is similar to Empty.

Space case

An interesting discussion about an addition to the group of CamelCase, snake_case and kebab-case: the space case, which looks like allowing space characters as part of identifiers. Shudder.

Perl 6 gather, I take

Arne Sommer has written a blog about gather and take, in which he shows several approaches to scrolling lines of text on a screen with a given delay. All part of preparations for his class at PerlCon 2019 (Reddit comments). .

Winding Down

The original main article of this Perl 6 Weekly was an April Fool’s prank that involved both Perl 5 and Perl 6. It seems however, that yours truly would be the last person that should be allowed to do such a prank. It’s all serious business. Unjokingly, eviction from the community was suggested. Hopefully see you next week for less serious Perl 6 news. 🙂
