This week saw a new Rakudo compiler release (2022.12 by Justin DeVuyst) with a nice bunch of new features and bug fixes, a new Cro release (mostly to fix a testing issue that would inhibit installation by default) and a new release of the Podlite editor (0.4.0, with markdown block support, /r/rakulang comments). Nice prezzies!

Raku Advent Calendar 2022

The fourth Raku Advent Calendar has started with an introduction by JJ Merelo and the following contributions so far:

• Day 1: SparrowCI pipelines for everything by Alexey Melezhik.
• Day 2: Less Variable Wattage = More Flow by Nigel Hamilton (/r/rakulang comments).
• Day 3: Santa and the Rakupod Wranglers by Tom Browder.
• Day 4: Give the gift of time by JJ Merelo.
• Day 5: Malware and Raku by Paula de la Hoz.

Meanwhile, Daniel Sockwell is still looking for a volunteer to write an advent post about the idea: “I’m disappointed by dynamic typing“.

Chris Jarvis has posted a nice overview of Advent related events, and EditorDavid also has a list.

Core Developments

Winding down

So many new things this week! And yet another new name in core development!

This week’s picture is to remind us of sunnier days in these dark days before the winter Solstice! Also 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!
