2021.20 Cro Nodelayed

Alexander Kiryuhin, Jonathan Worthington and vendethiel released Cro 0.8.5, the library for building reactive distributed systems taking advantage of all that the Raku Programming Language has to offer. Most important new features are the use of TCP_NODELAY by default (which improves network performance) and on-demand reloading of templates in development environments.

This release comes about 6 months since the previous release and has kindly been supported by Edument. The next release is planned for July 2021 (roadmap).

A new IRC::Client

Patrick Spek has been working on a new version of IRC::Client, a popular module for doing stuff with IRC, such as creating IRC bots. It’s almost compatible with the old version, but with some notable differences. This week they’ve blogged about it and how this will potentially affect users of IRC::Client (/r/rakulang comments). Please let your thoughts be known!

Call for Grant Proposals

Although one can commit a Grant Proposal for a Raku project any time of the year, it is good to sometimes be reminded that another round is coming up to a deadline. So it’s not too late to submit your proposal for the May Round of the Foundation Grants.

Conference Season

Sadly, it is not possible to have in-person conferences yet, so there’s the 2021 Conference in the Cloud instead (8-10 June 2021, schedule, FaceBook). The following presentations are planned that are about the Raku Programming Language, or that touch aspects of it:


Weekly Challenge #113 is available for your perusal. And this week’s “What’s everyone working on (2021.20)” as well.

Core Developments

Clearly a very quiet week, with most of the core developers working on non-core Raku projects.

  • Nicholas Clark fixed some valgrind warnings when HASH_DEBUG_ITER was defined, implemented MVM_num_isnanorinf using isinf and isnan.
  • Stefan Seifert fixed an issue with the optimization of smart_intify.
  • Daniel Green fixed some issues on the Continuous Integration pipelines.
  • Stoned Elipot tweaked some texts.

New Raku Modules

Note: these still do not include modules added / updated to the zef ecosystem yet. Need to find some tuits to automate fetching that information or someone else to fix this before yours truly has time for it (nudge nudge).

Updated Raku Modules

Winding down

A lot of stuff happening in the background again. Such as the Raku IRC Log project, that has a alpha-version running, which has taken most of yours truly development time the past week. Otherwise, plenty of stuff to read again about in this week’s Rakudo Weekly News! And to repeat once again: stay healthy and stay safe! See you next week!
