Put this in your agenda: the second Raku Conference will be held on 13-14 August 2022, online!
An online meetup for all people interested in the development of the Raku documentation, is planned for 9 July 2022 at noon Eastern Time (which is 16:00 UTC). Please check the #raku-doc IRC channel for more information.
Anton Antonov continues to be on a roll, introducing
ML::ROCFunctions in a blog post (part of a framework for analysis and tuning of binary classifiers).
Steve Dondley wrote an introduction to their new
Did You Know?
That you can refer to previously calculated values in the REPL?
$ raku  > 42 42  > 666 666  > say $*0 + $*1 708  > say @*_ (42 666) 
Note that each time a value has been calculated (without it having been explicitely displayed with e.g.
say), the number before the prompt (
> ) is incremented. In any new expression, you can refer to these values by index:
$*0 (e.g. in
say $*0 + $*1). The scalars are actually shortcuts to the underlying
@*_ array, which you can also access directly.
Please note that
$*0 (and friends) and
@*_ only exist in the REPL, and nowhere else!
Weekly Challenge #172 is available for your perusal.
New Pull Requests
- Solution for #328
max AssetPackversion in cpanfile

- Implement coercion via new-disp
- Add a help function to the repl
- Vadim Belman added methods
- Ben Davies made sure that
Associativetype parameters are considered in optional defaults.
- Stefan Seifert continued working on the RakuAST branch: supporting invocant markers, handling cloning of stubbed code objects, assigning to native attributes, support for
Whatevercurrying, implementing support for
notandthenand fixed issues with sinking. This resulted in 512 roast files now fully passing (and without needing a normal spectest run first). Wow!

This week’s image was made enjoying a small train ride in the neighborhood. It is there to remind us to support Ukraine in their fight against the Russian aggression. Слава Україні! Героям слава!
In the mean time, please stay safe, stay healthy, keep up the good work! ‘Rona is most definitely not over yet.
If you like what I’m doing, committing to a small sponsorship would mean a great deal!
How many roast files are there? Just trying to get a feel for the progress reports on RakuAST 🙂

1353 at current count. Mind you, this is not really an indication of the amount of work that still needs to be done. Many failures depend on the same feature not being implemented. Once implemented, the failing test files either pass or fail for a different reason. Judging from experience with the Great List Refactor, I’d say we’re now past 50% of the necessary work (even though you wouldn’t expect that seeing the 512 / 1353 figure).
