If I streamed every time I face any computer related issues, I would be a 24/7 streamer.

We with Joseph made a short, but important guide about Load Paths for Guile developers.

#guile #guix

- Did you know that Guile's metacommands are comming to Arei soon?
- That we already have an incredibly useful guile stack traces viewer?
- That Ares now works with stable version of Guile and doesn't require guile-next?

No? We got you covered:

Recently, I've received my first donation from @nlnet for suitbl, an interactive testing library for Scheme.

Their support allows me to allocate a lot of time to the development of the library. I still need to finish a few more parts before I can recommend it for adoption, but you already can take a sneak peek at the library & its usage here:

Kudos to @nlnet for backing great FOSS projects in general and me in particular :D

If I survive to this Thursday, we will have a very nice and cozy RDE Meetup #6.

Some of the topics:
- Work and Success on Guile Debugger.
- What is left to do for Arei/Ares 1.0 release?
- Custom keyboard layouts in Guix.
- Emacs 30, completion preview, LLMs, Japanese fonts and input methods ツ

The full announce and join instruction is here:

@baleine and I have been messing around with Guile's Stack Traces and now they are freaking awesome.

One of the biggest video bloggers on the planet (PewDiePie) uses linux:

I just didn't expect it. I had a very strong stereotype that most people trade freedom, privacy and all the must for convenience.

I couldn't imagine a non-tech person so much integrated in capitalism to find time and desire to have a fun tinkering and ricing Linux.

Kudos to PewDiePie.

What are the best materials on hygienic macros?

I went through the https://www.greghendershott.com/fear-of-macros/

I think I got the basics, but still very puzzled. For example I faced syntax-id-rules in a paper, which is Racket-specific and now I'm curious how to implement the same functionality in non-racket Scheme?

Also, plan to go through
https://mnieper.github.io/scheme-macros/README.html

Streaming about testing library for Scheme, NLnet grant, its integration into Arei/Ares Guile IDE and some library architecture design thoughts in a couple hours. It's inspired by clojure.test and junit, but still quite schemy.

I was installing a program to my android device and realized how much I appreciate the way Guix packages software. It contains only bootstrapable Freedom and Privacy respecting programs and libraries.

It's like a Quality mark: If the package in the repo I'm pretty sure that it's built from source code, it has no blobs, no telemetry and no backdoors. There is no man-in-the-middle in my supply chain.

comp.lang.scheme > An Advanced Syntax-Rules Primer for the Mildly Insane

I'll just leave it here.

Look at what is coming to Scheme ecosystem:

Warming up the meetup!

RDE Meetup #4 will happen on March 13 (less than one week left).

Please fill an optional registration form and send questions and thoughts that bother you to it :)

Everything about #rde, #guix, #scheme and #guile is related (but maybe not everything will be covered on the meetup 🤭 )

I'm curious: is it too geeky stuff to talk about out loud or is it still ok?)

BTW, today I implemented `syntax->list` using a `syntax-case`. I needed it to get a list of values from args pattern variable of (arg1 args ...) pattern.

And only now I realized that I don't actually need it, because #'(args ...) is already a list in Guile.

It solves my previous question about syntax->list I had last week:
https://fosstodon.org/@abcdw/114018596208278873

Today I learned that Racket and Guile represent syntax objects for lists differently.

I don't know yet which one I prefer, because in Guile `syntax` not always returns a syntax-object as one could expect, sometimes it returns a list.

(use-modules (system syntax))
(syntax? (syntax (+ 3 4))) ;; => #f
(syntax? (syntax hi)) ;; => #t

On the other hand TSPL4 book says that #'(+ 3 4) returns a valid list.

Who read RnRS? What does it say for this case?

TIL: There is a builtin completion-preview-mode in recent Emacs.

Guile and RDE Intenships.

RDE applied for GSoC 2025 as a mentoring organization. The results will be on February 27.

I put the list of the project ideas here:
https://trop.in/rde/internship

However, GSoC is not the only way to do the internship. We have some funding contributed by our community members https://opencollective.com/rde and can arrange an internship regardless. Just contact me or drop a message on rde-discuss for details.

#guile #guix #rde #nix #scheme #webassembly #nrepl #vscode #foss #floss

I think RDE is already big enough to apply for GSoC as an organization, so I started to write it! :)

What would you like to see implemented in RDE, Arei, Ares, Guile, Guix in the nearest future?

Maybe VSCode frontend for Arei/Ares Guile Scheme IDE? Or more capable and advanced configuration DSL for RDE?

https://lists.sr.ht/~abcdw/rde-discuss/%3C87msf3rt6i.fsf@trop.in%3E

P.S. Let me know if you would like to mentor one of those projects.
