Justin DeVuyst was able to release the 2022.07 Rakudo Compiler Release just before the end of the month. Which added inode, dev and devtype methods to IO::Path, and a new .snip method (inspired by Haskell’s span). And many other improvements and fixes! Updated Linux packages are now also available on rakudo.pkg, thanks to Claudio Ramirez.

Comma Release

Jonathan Worthington and their team also released new versions of the Comma IDE, both the (paid) Comma Complete, as well as the (free) Comma Community edition. New features include better real-time reporting of IO and concurrency in your programs! Check it out!

Wenzel’s Corner

Wenzel P.P. Peppmeyer got too many Sundays to handle in Swarming Sundays.

Anton’s Corner

Anton Antonov continues their work on Machine Learning with an extensive blog post about the fast classification of DSL commands. Good to see Raku being used in the scientific world!

$ script-name --foo=False
$ script-name --/foo

However, many people are used to be able to specify --no-foo as a way to indicate that the foo option is False. And this is not supported by Raku. Fortunately, there’s a simple trick that you can add to your script to allow this transparently:

$_ .= subst(/^ '--no-' /, '--/') for @*ARGS;

This looks at the raw arguments (as available in @*ARGS) and changes any arguments starting with --no- to --/ (which is an accepted format in Raku’s standard way of interpreting command line arguments). After that, it’s just as if users of your script typed --/foo instead of --no-foo.

Winding down

A bit of a quiet week, with a lot of people on vacation, and others preparing software releases and/or presentations for the 2022 Raku Conference!

This week’s image again there to remind us to support Ukraine in their and our fight against the Russian aggression. Слава Україні!  Героям слава!

In the meantime, please stay safe, stay healthy, keep up the good work! ‘Rona has gotten competition 😦

If you like what I’m doing, committing to a small sponsorship would mean a great deal!
