Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The origin and virtues of semicolons in programming languages
* list of list literals (1,2; 3,4) eqv ((1,2), (3,4));
to paraphrase Larry Walk “everyone wants the [semi] colon”

Dada, an Experiement by the Creators of Rust
amen to this … i recommend thinking about your problem in terms of effective data structures and then apply even a very simple DSL to handle access and transformations … fwiw the built in Grammars and Slang support in raku https://docs.raku.org are fantastic tools for this job.

Raku: A Language for Gremlins
When I was looking at the language, I didn't find the documentation "really poor". In fact I was impressed at how much of a one-stop-shop the official docs site was for both conceptual docs and API docs.

Migrating Perl to Raku
The Raku Programming Language documentation already contains most (if not all) the documentation you need to deal with the issues you will confront in migrating Perl code to Raku. But, as documentation goes, the focus is on the factual differences. These blogs will try to go a little more in-depth about specific issues and provide a little more hands-on information based on my experience porting quite a lot of Perl code to Raku.

Introducing Pod Renewal Initiative
I will start working on the new version of Pod as a branch in https://github.com/raku/doc.

Will Carbon Replace C++?
Well, performance has been improved by several orders of magnitude since the first release. So maybe it's time to look at https://raku.org again (or first have a look at its new documentation site https://docs.raku.org)
-
What do yall use raku for?
go to https://docs.raku.org/ and type "IO" into the search field. Behold the list that appears. Check out IO::Path or IO::Handle or whatever looks interesting. Maybe it's just me but I go "Ooh, look at all the things!".

Generating a hash without a helper function
Related: The Raku documentation does an excellent job explaining hashes/dictrionaries/associative arrays. If you've any issues, please submit a Github issue.

What are the best materials for learning raku?
Raku has a lot of syntax. My first attempt at learning the language failed because I couldn't get past all the strange syntax I saw at https://docs.raku.org/. Sometimes I didn't know what the syntax was called, so I didn't know what to search for.

2021 Advent of Code solutions in the Raku programming language
In the course of figuring this out, I realized that our docs also (slightly) misstate what \d means in a Regex, which led to this PR. So thanks for bringing all this up!

Moving printf formats forward
This then became the Formatter class. And since this was a completely new feature, it only became available for use by opting into the 6.e.PREVIEW language version. And then it went largely unnoticed and uncared for the next 1.5 year. As clearly the time wasn't right for it yet.

Shaking the RakuAST Tree
The intended audience are those people willing to be early adopters of these exciting new features in the Raku Programming Language. The examples in this blog post will work in the next release of the Rakudo compiler (probably 2023.06), but are now already available in the bleeding edge version.
-
So why is there RakuAST in the first place?
If you really want to look at this, you can find the code in src/Perl6/Grammar.nqp, src/Perl6/Actions.nqp and src/Perl6/World.nqp.
-
A practical example of RakuAST
If you find this very interesting, you probably want to read the RakuAST README. And the actual source code of the RakuAST classes can be found in the same directory. And if you're really feeling adventurous and you have the Rakudo repository checked out, you can have a look at the generated NQP code in gen/moar/ast.nqp.
-
RakuAST for Early Adopters
Yes, it would. But until there was RakuAST, that was virtually impossible to do because there was no proper API for building ASTs. Nor was there an interface to execute those ASTs. And now that there is RakuAST, it is actually possible to do this. And there is actually already an implementation of that idea in the new Formatter class. Although this is definitely not intended as an entry point into grokking RakuAST.

What explains this difference in behavior?
I have opened one. https://github.com/rakudo/rakudo/issues/5205.

Building Rakudo on JVM backend fails: guarantee(requested_word_size <= chunklevel::MAX_CHUNK_WORD_SIZE) failed: Requested size too large (561049) - max allowed size per allocation is 524288
There's an issue pertaining to this. This is something I'd like to resolve, but I'm unsure on how to better debug this to see if it really is the deserialization of a setting file triggering it. JDK 11 should at least be capable of building Rakudo, but being an experimental backend people don't always align with MoarVM immediately, I can't make any guarantees about tests. You may be disappointed in its performance at the moment.

Resources and advice
(NB. While the PL is just a toy (and just a tiny bit of the toy too), the tech is actually industrial strength, used to power the production Raku compiler, which is written in Raku using its grammar construct. Starting easy doesn't mean you can't go far. Quite the opposite in fact -- you can go as far as you want.)
