2022.46 Rainbow Butterfly

Sometimes good ideas almost fall through the cracks! In September the TPRF suggested the idea of setting up a yearly Rainbow Butterfly Award to be awarded to the person who has done outstanding non-core support for the Raku Community / promotion of the Raku Programming Language (discussed in the Raku Steering Council meeting of 17 September).

Please consider who you would like to receive the Rainbow Butterly Award 2022 by sending your nomination by email to: rainbow@raku.org . And if at all possible, add your reasons as to why the nominated person should receive the award! Nominations will be accepted until the 1st of December, after which the Raku Steering Council will deliberately choose and announce the winner.

Thank you, Roman

Roman Baumer, one of the people keeping the Raku infrastructure up and running, has indicated that they do not have the time anymore to properly support the Raku infrastructure. This means that we’re looking for people willing to take care of the day-to-day running, as well be able to support new developments of the Raku infrastructure. Please send an email to infra@raku.org if you’re interested!


The FOSDEM organization has announced the developer rooms for the 2023 edition of FOSDEM on 4/5 February 2023 in Brussels. Followed by a Call for Participation. Check out the devrooms and figure out where you could do a presentation of some aspect of the Raku Programming Language that would be of interest of the people in that devroom. You can also claim some financial support by TPRF!

New Problem Solving Issues

Core Developments

  • Daniel Green fixed an issue with signedness of arguments to nqp::chown.
  • Salvador Ortiz optimized some tests during compilation of Raku code.
  • Vadim Belman fixed a static optimization issue and a recent regression in handling of the :2b syntax with smartmatching in some situations.
  • Elizabeth Mattijsen added a .days-in-year on Date / DateTime. And added a chown sub and IO::Path.chown method, based on Daniel Green‘s work.
  • Stefan Seifert was working on the RakuAST branch again, getting all of the NativeCall tests to pass! Tests now at 551/1355 (+2) and 78/131 (+2).

Winding down

A bit of a quiet week again, while plenty going on in the rest of the world.

This week’s picture shows nature at work again! To remind us Ukraine is still fighting the Russian aggression. Слава Україні!  Героям слава!

In the meantime, please keep staying safe, keep staying healthy, and keep up the good work!

If you like what I’m doing, committing to a small sponsorship would mean a great deal!
