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.

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.

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.

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.

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.

I have opened one. https://github.com/rakudo/rakudo/issues/5205.

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.

(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.)

Please pay attention if you want to dig really deep )) , then underlying SparrowCI itself is just a transpiler from YAML ( plus some more features ) into Sparrow DSL which is documented here - https://github.com/melezhik/sparrow6 but you probably don’t need that part if you are only interested in writing pipelines …

As an addition to what's been already said, you might distribute your personal libraries as Sparrow plugins and spin up a private Sparrow repo for that - https://github.com/melezhik/Sparrow6/blob/master/documentation/repository.md , it should not be very hard and by they way Sparrow is well integrated with zen by using Rakufile mechanism - https://github.com/melezhik/Sparrow6/blob/master/documentation/development.md#package-managers , so one can distribute any ref modules (including taken from git , not eco system ) by just including Rakufile into one's plugin ...

I think alternatives to Ansible such as Rex and Sparrow have "fake it and show me the commands" modes — but I'm not 100% sure.

I'm not sure if there is a full fledged web framework for Raku just yet, but one of its claims to fame is Sparrow. It's declarative configuration management akin to Puppet, Chef, or Ansible.

Sparrow an automation framework, and its modules

During this stage Bird will use prepared task checks rules (check file - /root/.bird/285892/state.check]) and run them against the output. Bird will use Sparrow task check DSL to do so.

1) Sparrow - https://github.com/melezhik/Sparrow6 Raku Automation Framework ( alternative to ansible )

Sparrow is a wonderful tool to automate @daily devops tasks. Recently I've dropped a new plugin called k8s-deployment-check to verify k8s deployments. It lets you with a little bit of Raku code effectively test entire k8s infrastructure, including k8s deployments.

Could be added pretty easily, Sparrow has cpan-package primitive for for that.
