Zoffix Znet announced (Reddit comments) a new way for the Rakudo Perl 6 core development team to communicate with its users, using all of the current ways of dispatching alerts in the social media world we live in: Perl 6 Alerts, with an associated RSS and Twitter feed. And if that’s not enough, you can write your own alerter using the API with the
WWW:P6lert module. All of this put together in a few days using Cro and the Rakudo Perl 6 Programming Language. So please make sure you subscribe to the desired means of alerting if you want to keep abreast of Rakudo Perl 6 core developments.
Yours truly wonders whether the publication of yet another Perl 6 Weekly would warrant an
info level alert or not. Probably not.
Keeping on Adventing
It was so nice to write something for this year’s Advent calendar that I decided to continue. It was a surprise to me that the sources of Rakudo are so interesting material to explore and read, and I want to share that feeling 🙂 Hopefully, daily.
So far, he has posted:
- Exploring the
Booltype, part 1
- Playing with code
- Exploring the
Booltype, part 2
- Lurking behind interpolation
- Digging into operator precedence, part 1
- Digging into operator precedence, part 2
- Obsolete syntax warnings, part 1
- Obsolete syntax warnings, part 2
- Compiler stages and targets
Guess what? Even yours truly learned a few tidbits from these posts, so please keep them coming!
But that’s not all: he also re-started his Russian language Вечерний Perl 6 (Evening Perl 6) daily blog posts with an overview of Rakudo Perl 6: Что где про Perl 6 (What about Perl 6?). So check it out, if you can!
In 2017 the Perl 6 Facebook Group has gained 127 new members (from 340 to 467 members, so an increase of 35%). On the commit front: well over 10000 commits of which 2272 documentation, 1669 roast, 1829 MoarVM, 1258 NQP and 3507 Rakudo commits (and 370 Rakudo Pull Requests). On the release front: 14 MoarVM, 15 Rakudo compiler and 4 Rakudo Star releases. 842 lines in the MoarVM ChangeLog and 1368 lines of ChangeLog in Rakudo. 768 Tweets on the Perl 6 News Feed, 266 Questions on StackOverflow and at least 123 questions on the perl6-users mailinglist that got mentioned in 52 issues of the Perl 6 Weekly. 238 tickets got resolved and 241 new tickets got added in the 20 week period in 2017 when these statistics were centrally kept. Seven Perl 6 books got published. And 3 new core developers got their Rakudo commit bit. Let’s try to top these numbers in 2018!

- Zoffix Znet was very busy again: among other things, he fixed some dispatch issues with
Whatever.ACCEPTShandling of type objects. IEEE-style Rationals for ±
Numconversions got overhauled, fixing 3 tickets in one blow. And he improved the USAGE message of
MAINquite a bit. And he fixed an issue with the flushing of TTYs on Win10.
- Zoffix Znet also did some performance enhancements:
Blob.subbufis now 1.8x faster, and an
ifin sink context that evaluates to
False, is now 3.4x faster.
- Jeremy Studer made sure that interpolated quotewords (
« ») don’t produce a
Slipif they only consist of a single word, and that assigning to an element of a
Rangeproduces a better error.
- Christian Bartolomäus continued his quest to keep the JVM backend, and the testing of it, in working order.
- Dan Zwell made sure the
printfformat is not used on Windows, as it’s unsupported there.
- Timo Paulssen made sure the
nqp::isprimeop gets JITted. This removes any unnecessary overhead of determining primality on a large set of numbers. He also made adding an
Rat22% faster, and fixed a problem with
Buf.subbuf‘s handling of degenerate
Ranges such as
- Elizabeth Mattijsen sanitized the behaviour of
- And many other smaller fixes and improvements.

It’s always weird in the first Perl 6 Weekly of the new year to be reporting about things in the previous year. Especially when the first Perl 6 Weekly of the year is published on the first day of the new year. To yours truly it feels that all of this is a bit of old news, in preparation for some pretty amazing things that will come to the world of Rakudo Perl 6. So, please check in again next week for some serious new stuff of 2018!
