Hi @jeko, I started reading and following along your book https://jeko.frama.io/en/index.html . Thanks for writing it ! Will share feedback when I am done #guile #scheme #book

We develop rde on sourcehut, but there is a mirror on github and recently I realized that it has 185 stars already:
https://github.com/abcdw/rde

How many it is?

Do you know other small to medium sized projects, which only mirrors on github?

I'm going to be poking at #GNU #Guile. In particular, I'm curious about the impact of defining core procedures like car as generics. Does this cause intolerable performance losses in built-in libraries? How much integration does this actually provide for user-defined data types?

What is this?

Because, #Guile.

🔴 Today on #SystemCrafters Live, we'll learn how to use Guile Hall, Guix and Emacs to develop new Guile Scheme libraries! With these tools you can scaffold new projects with everything you need to start hacking.

As an experiment, we'll use them to prototype a simple URL route handling library!

Starting a second stream on lightweight concurrency in Guile Scheme:

The best way to get all available stuff from textual port I found so far is:
(define (read-all-chars-as-string port)
(let loop ((chars '()))
(if (char-ready? port)
(loop (cons (read-char port) chars))
(reverse-list->string chars))))

When you want a cryptography library for #guile, you might be pushed to use guile-#gcrypt. I advise you to use #gnutls instead: since guile use gnutls for its web stack, it might save you a dependency, while adding lots of cool features (e.g. parsing PEM keys, a requirement for ActivityPub interoperability with Mastodon).

For instance, here is how #goblins could use it:

@jeko
I never got round to looking at direnv and somehow felt something was missing.

Did contribute [M-x] guix-set-emacs-environment to emacs-guix...and while that was very clumsy, it worked just too well for me, or so I thought :-)

Keep experimenting with fibers and for a good reason I need an operation, which waits until thread is exited.

I implemented it and it works, but obviously blows up the memory. I've not finished a "Parallel Concurrent ML" paper and have a very little clue what I do in block-fn, I'll appreaciate if someone can give me a quick solution for now.

The explanation on what is happenning with #scheme language r7rs standard at the moment:

The work on r7rs-big is tough, but I hope it will go through this hard times.

Finally found the time to play with this -- amazing!

Thanks for the awesome guide!

De mon côté c’est en place, merci à #guix de me laisser scripter mon système en #guile.

[LISP/SCHEME] Guile Hacker Handbook in Italiano.

@programmazione

Amicɜ, da qualche mese mi sto interessando alla famiglia di linguaggi Lisp/Scheme e, nel processo di ricerca, mi sono imbattuto e ho tradotto l'handbook di @jeko

È molto interessante, in continuo aggiornamento ed è orientato alla Test Driven Development.

Spero possa esservi utile!

Se trovate qualche errore o avete feedback sulla traduzione scrivetemi pure.

Grazie 🙏

Found a nice talk on concurrency. It has a very brief comparison of different concurrency models, like Erlang's Actors, Hoare's CSP, Go's goroutines, Clojure's core.async, Concurrent ML (aka Fibers in Guile).

Primary focus on Concurrent ML (but examples are in Scheme with type annotations ><).
