What a wonderful morning!

What a new Guile release!

SRFI-197 (pipeline operators) is now builtin, custom ports and a lot of other features and fixes are finally landed.

Now, it's time to update Guile package in Guix and we are ready for a release of Arei/Ares 1.0!

An opinion: #Lisp, #Scheme, and #CommonLisp macros should also include type information, not only forms to process. The language(s) are typed, after all!

Luckily, this can be added on top of the existing macro system with… macros! And some compiler internals for type inference, in the order of what trivial-arguments are doing (disclosure: I’m the one that contributed type info fetching there.) With that and some syntax processing, one can infer the type of a given expression in like 80% of cases (might be less than that on non-SBCL compilers, but I have to test that.) And then act on it with a knowledge of what types there are.

I had a use-case for this when playing with CRUNCH, but it eludes me now. You have to believe me on the usefulness of types in macros.

I think I'm going live again because I'm having a very cool chat with people when I do. About programming, studies, interpreters... many things!

Also I have to say the issue that I have to track today is weird.

#GNU #Mes ( #scheme & #c #programming) bug hunting night.

🚀 New chapter added to the Guile Hacker Handbook 🚀

This is a book to learn #Guile in a #TestDrivenLearning style 👽

Contrary to what I have said previously, this new chapter is about having some fun using the use-cases in the REPL.

Olive CSS (v0.1.5) a Lisp powered utility class vanilla CSS framework that allows opinionated "Tailwind-like" syntax and custom optimized production builds - no JavaScript (all Guile Scheme λ )

https://codeberg.org/jjba23/olive-css

You can use this in any web project, it is vanilla CSS, and it serves as a kind-of drop-in replacement for Tailwind so the syntax is mostly transferrable.

This may be what finally pushes me over the edge to become a normal person by finally ditching #Chez #Scheme for Racket:
"With the version 9.0 release, #Racket includes support for shared-memory threads that can take advantage of multicore hardware and OS threads to run in parallel— not merely concurrently with other Racket threads, as was the case in versions before 9.0."

My main complaint about #Scheme is that it’s “not practical,” being non-portable and batteries-excluded for any sufficiently complex case. And yet my current situation (my #LambdaCalculus experiments, aspirations for the Web-resident software that’s NOT necessarily #JavaScript, and overall feeling that #CommonLisp is quite trippy when I write it) kind of nudges me towards Scheme. The appeal is real.

@Sandra is partly to blame for that, showing all these beautiful combinators off in her posts. Combinators are cool, and Scheme is (almost) a perfect language for them!

Hello everyone 👋

On Wednesday 3rd of December Bost and me will give a session on #guix at the Functional Programming Night in #Tübingen.

Guix is a Linux distribution and package manager inspired by Nix. It allows bitwise reproducibility of software, fine-grained roll-backs, transactional installs and a lot more!

I'll give an introduction into Guix. Bost will show you the good and the not-so-good parts. And in the end there'll be an open stage about workflows/use-cases (also #Nix).

If you come, please register beforehand. There'll be free pizza and drinks! 🥳

Date: 2025-12-03 (Wednesday)
Event start: 18:45
Location: itdesign GmbH (Blaue Brücke, Tübingen, Germany)

Now is the time to submit a talk for the declarative and minimalistic computing room at FOSDEM

https://lists.fosdem.org/pipermail/fosdem/2025q4/003662.html

If you're into #guix or #declarative #linux then there's lots of interesting areas.

Some ideas:

* building and configuring #guix and #guile #scheme - how particular services are used.
* #guix and containerization / #docker
* deploying #guix services in the cloud / on servers
* running #guix on a hosted Linux distribution like #debian #ubuntu or #suse
* managing development work flows

And so much more ...

It's a super friendly room so submit your talk now! Or talk to @pjotrprins
