Daniel Sockwell took Mike Clark‘s ideas a bit further and wrote an extensive blog post with further thoughts on cooperative grammars, in which they show the use of different grammars to parse the CSS parts of an HTML file (as a proof of concept). Which in turn caused quite a discussion on /r/rakulang.

Grant Update

Jonathan Worthington reported on the progress of the RakuAST Grant (/r/rakulang comments).

Steve’s Corner

Steve Roe published two blog posts this week:

• Raku Physics::Unit vs. Python Pint (/r/rakulang comments)
• Python Pint vs. raku Physics::Unit Comparison Table (/r/rakulang comments)

Updown lists Raku

Updown.io, a site for simple and inexpensive website monitoring, now also lists the Updown Raku distribution in its list of client libraries. Note that raku.land is also a client of Updown’s services.

Weeklies

Weekly Challenge #153 is available for your perusal.

New Problem Solving Issues

We don’t get many of them, and they probably need as many eyes on them as possible, so these will now be listed in the Weekly from now on as well:

• Make grammars called from grammars more intuitive
• Preparing the Raku Ecosystem for the Future (/r/rakulang comments)
• Uniform approach to distributing important messages about Raku

New Pull Requests

• Bump mimalloc to v2.0.5
• Allow optional : on LHS of signature binding declaration
• Make $*_ be the last value evaluated in the REPL

Core Developments

• Jan-Olof Hendig bumped libuv to version 1.43.
• Daniel Green made the code generation of ++$i the same as $i = nqp::add_i($i,1) for native integers.
• Christian Bartolomäus added the coerce_ns on the MoarVM and JVM backends.
• Elizabeth Mattijsen streamlined a lot of setting internals to use fewer nqp ops, to improve readability.
• Patrick Böker fixed the semantics of IO::Path.parent in some (important) edge cases.
• And some other smaller fixes and improvements.

Questions about Raku

• How to retrieve the last result in the shell (like “Ans” in calculators) by tokujin.

Winding down

A bit of a quiet week. Still enough to read and catch up on!

Next week’s Rakudo Weekly news about the Raku Programming Language may be delayed to Wednesday, or even be skipped at all, as yours truly will be busy on the Monday / Tuesday with other stuff.

In the meantime, stay healthy and stay safe!
