The next phase of the removal of the original “p6c” ecosystem has started. Elizabeth Mattijsen reports on the progress so far with “The End Of p6c”. In short: 99 modules removed from “p6c”, 23 modules transferred to the zef ecosystem and 13 modules moved to the Raku Module Adoption Center (of which 5 still need some TLC).

Dr. Raku’s Corner

Dr Raku‘s beginner tutorial videos of the past week:

• Regex Match Start & End Of String
• Extract Trim String Characters

Weeklies

Weekly Challenge #282 is available for your perusal.

Core Developments

• Daniel Green added fast paths for concatenating short strings, and hashing of in-situ (short) strings.
• Stefan Seifert changed the behaviour of throws-like (for the better) in light of compilation errors.
• Elizabeth Mattijsen removed a test-file that had a single test for a feature that will very likely never be implemented (in core).

In RakuAST developments this week:

• Stefan Seifert continued working on RakuAST, fixing: error messages, operator properties on custom operators, several meta-operator and hypering issues, dispatch using .?, .+ and .*, adverbs on infixes, and more.
• Elizabeth Mattijsen fixed issues with E<> and C<> RakuDoc markup, and made syntax highlighting return a Failure if compilation of the given source failed.
• The number of passing test-files with the new Raku grammar are now 142/153 (make test -4) and 1085/1355 (make spectest +16) exceeding 80% passing for the first time!

Recently Migrated Modules

These modules have been recently migrated to the Raku Module Adoption Center and have not been re-released yet because they need some more Tender Loving Care.

• PrettyDump
• Text::Markdown::Discount
• Net::FTP
• Net::FTPlib
• App::snippet

Any help with these modules will be greatly appreciated!

Winding down

Quite a lot happening in module land, as well as with RakuAST. Good stuff! Meanwhile, still: Слава Україні!  Героям слава!

Please keep staying safe and healthy, and keep up the good work!
