Brian Duggan wrote a nice blog post about their use of the Raku Programming Language in their solution of 2022 Advent Of Code problems (/r/rakulang comments).

Anton’s Corner

Anton Antonov reminded us of a presentation they gave at the 2022 Wolfram Technology Conference, which featured a Cro webservice frontend.

Rawley’s Corner

Rawley Fowler mentioned that Humming-Bird (A simple, composable Web Framework) is now stable.

Alexey’s Corner

Alexey Melezhik published a blog post about the new “hub” (aka dynamic CI pipelines) feature in SparrowCI.

FOSDEM mini grants

Thinking about going to FOSDEM in Brussels on 4/5 February? You might be eligible for a $300 mini grant! (/r/perl comments)

Weeklies

Weekly Challenge #200 is available for your perusal.

New Problem Solving Issues

• Expand DEPRECATED functionality.

New Pull Requests

• Reconsider language versioning and implement language version support in RakuAST
• Simplify Supply / whenever processing order

Core Developments

• Stephen Schulze updated MoarVM’s / Rakudo’s Unicode support to version 15.0!
• Stefan Seifert worked a little on adding RakuAST grammar features again (supporting constants as parameter constraints, implement let and temp, and for returning Nil), increasing the number of completely passing test files: 618/1355 (+12 make spectest).
• Elizabeth Mattijsen implemented many RakuAST deparsing tests (adding 3 test-files), which sadly lost us one completely passing file 94/137 (-1 make test).
• And some smaller fixes and tweaks in the RakuAST realm.
