Jo Christian Oterhals has returned with a nice blog post on How to mess up
for loops in Raku, inspired by a tweet of Joelle Maslak (/r/rakulang comments). The blog post explores the ways you can call a piece of code repeatedly in the Raku Programming Language. Including ways you probably shouldn’t. Learning by bad example!
Writing a Clipboard Manager
Nguyễn Gia Phong wanted to give a presentation at the upcoming Raku Conference, but instead decided to convert their presentation to a blog post: Writing a Clipboard Manager. The reason for this conversion started a discussion about the online conferencing software to be used.
Writing devopsish tests
Alexey Melezhik has written a quick introduction into Tomty, a Raku test framework with focus on devops tasks: it allows one to write test scenarios in Bash and orchestrate them using Raku.
- Clarify Problem Solving process description in README
- Fix memory corruption by accessing freed spesh stats
- Fix serialization gc issues
- Fix some errors WRT curried role typecheck lists

- And some other smaller fixes and improvements.
Meanwhile, Jonathan Worthington continued their work on the
new-disp branch, mostly solidifying the work of the past weeks.
