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

@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

#scheme #guile #racket #lisp

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.

If you curios why lisp is cool, watch this.

In addition to very important mail subsystem refactoring we did, I showed how to decrease time spent building a configuration with Guix Home from 1.5m:

to a fraction of second!

P.S. Today is finally no-technical-issues-good-quality stream! Hack yeah! 🥳

#rde #guix #guile #emacs #lisp

Probably I found the cause of the issue with OBS: the audio/video got desynchronized, robovoiced and messed up probably because of webcamera frame rate being different from overall stream frame rate.

I'm almost certain it fixed now. At least 2 30 minutes test recordings went without an issue!

No more frustration during streams and video recordings? :)
