FOSDEM DevRoom

Currently, there have not been any Raku applications for the FOSDEM DevRoom so far. If you intend to attend FOSDEM on 3/4 February in Brussels, why not give a cool presentation of the Raku Programming Language as well? Perhaps modify an Advent Blog Post into a presentation?

David’s Corner

David Techwell has published a blog post about the behaviour of empty ranges: Raku Range Behavior: Understanding Empty Ranges. And it appears another nice blog post was missed by yours truly: How to Access State and Zipcode in Raku Grammar’s TOP Method. Removed this entry because it is ChatGPT generated spam.

Weeklies

Weekly Challenge #248 is available for your perusal.

New Problem Solving Issues

• How to organize the maintenance of localizations
• API for RakuDoc v2

Core Developments

• Elizabeth Mattijsen fixed a long-standing issue with regards to the <print> token and the Match.print method.
• Vadim Belman continued fixing issues in the instantiation of generics in the ecosystem.

In RakuAST developments this week:

• Elizabeth Mattijsen moved the localization module logic to the RakuAST::L10N module (making creating non-core localizations at lot easier), then moved all of the Raku localizations to the ecosystem.
• The number of passing test-files with the new Raku grammar are still 110/151 (make test) and 980/1356 (make spectest).
