It was only 3 years ago that the first official release of Perl 6 saw the light of day. Today, we are 36 compiler releases on, with the latest one, the 2018.12 release coming out a few days ago. Again done by Samantha McVey and Aleks-Daniel Jakimenko-Aleksejev, with Claudio Ramirez again taking immediate care of the Linux packages. It all seems so normal. And that’s a good thing! Although some applause is always appreciated!
Prepare Your Presentations!
Both the German Perl Workshop (6-8 March 2019) and the DC-Baltimore Perl Workshop (6 April 2019) have announced their Call For Presentations. The CFP for the German Perl Workshop ends on 20 January, and the CFP for the DC-Baltimore Perl Workshop ends on 31 January. What better time to contemplate your Perl 6 Presentations for 2019 than the Holiday Season? Or even better, prepare them?
Alexey Melezhik has written two blog posts about his latest product Tomtit: One Tomtit to make it and Automation of Perl 6 development workflow through the Tomtit task runner. A great new alternative to source code management and build automation! (Reddit comments).
Manage PostgreSQL Version (strings)
Luca Ferrari has written a nice blog post about a Perl 6 class to manage PostgreSQL Version strings in a Perl 6 program. A nice example of a small utility class. Too bad it isn’t in the ecosystem or on CPAN yet 😦
A new tool for language compilers
Andrew Shitov has had his presentation using grammars to design and implement a programming language accepted in the Minimalistic Languages track at the next FOSDEM (2/3 february 2019). Congratulations! (/r/perl6, /r/ProgrammingLanguages comments).
