Two compiler releases (x 3: MoarVM, nqp and Rakudo), 17 new modules released to the ecosystem, 38 modules updated and more than 110 documentation commits. Quite a nice crop for a single week! Yours truly hopes that this Perl 6 weekly won’t be tl;dr.
Rakudo Compiler Release
Aleks-Daniel Jakimenko-Aleksejev not only released the Rakudo Compiler 2018.04. But he had to do a point release as well to fix a problem with floating point literals that showed up only hours after the original release. Measures have been taken to not have this type of problem occur again.
Meanwhile Steve Mynott has prepared a Rakudo Star 2018.04-RC2 for people to try. This also contains a
MSI for Windows. And Claudio Ramirez is also preparing new packages for various Linux distributions.
Cro 0.7.5 Release
Jonathan Worthington released another milestone: Cro 0.7.5. Apart from many updates and improvements of existing modules, it brings two new modules as well:
- The Cro::OpenAPI::RoutesFromDefinition module, which supports implementing services specified using an OpenAPI v3 document (funded by Nick Logan).
- The Cro::HTTP:Test module, which offers a convenient way to write tests for (also non-Cro) HTTP services (funded by Oetiker+Partner).
Exciting new features for anybody wanting to write microservices with Perl 6!
CaR Grant Approved
The Bugfixing and Performance of Rationals Fixing Constraints on Constants Grant Proposal by Zoffix Znet has been approved and funded! Rejoice!
Pick that low hanging fruit!
Looking to get your hands dirty with some Rakudo Perl 6 work? There are lots of easy Rakudo Perl 6 tickets to fix. Talk to people on the #perl6-dev IRC channel if you need assistance in fixing them. We will all thank you for the fruits of your work!
