Whoop whoop

The latest version 2.11.9 #Caddy package has been built successfully on #Guix!

After some polishing steps it will be submitted for the team review.

Would anyone like to practice in writing Shepherds service?

#guixgoteam

The new 620.xx NVIDIA driver series is now available in Nonguix.

The old 595.xx series is deprecated and will be removed from Nonguix when its kernel modules fail to build with newer kernel versions.

I didn't try to enable BLUE's color support. Here's the same backtrace, but with colors.

#guix

Guix System (and Guix Home soon) has a few on-error strategies configurable via the --on-error= option. By default it's nothing-special, there're also backtrace (which displays a backtrace) and debug (which enters Guile's debugger).

I think backtrace is generally more useful to check one's configuration, but what it outputs appears to contain too little information. I was impressed by BLUE's backtrace when I started to use it, so I wonder what it looks like if it's used for Guix

The answer is actually quite simple: there's no magic in BLUE's backtrace, it just goes one step further ;)

The screenshot below shows the comparison, what Guix currently outputs (display-backtrace) on the left side, and with BLUE's print-backtrace on the right. They're almost identical, except that BLUE's also finds and outputs file content in addition to the line numbers.

btw I am Guix Committer now and just after that we got 4 and php incident, I updated php in guix the day it was released, so update if you haven't . uuf what a crazy welcome as a committer

New updates to the fish shell completion of Guix for changes in recent months and a few minor fixes!

In case you didn't know, since 2025 the fish completion covers all command-line options (and their required argument types when applicable), supports complex subcommand completion like guix time-machine -- shell -- guix deploy --execute -- guix time-machine --, and most importantly, is fast ;)

Making an effort to get #Guix back in shape in #Debian ... still lots of problems to sort out, and sometimes I question the wisdom of this effort, but here we go again!

tracker.debian.org/news/180829…

@Z572@mastodon.social told me there's a better approach dealing with git repository dependencies for Cargo, and I finally took a look.

Here's implementation! Will test it against relevant Rust packages in Guix. If everything goes well, we can finally stop packaging all Cargo workspaces in rust-sources.scm ;)

#guix

#Guix gained the ability to make your channel file essentially an alias for a remote channel file:
guix.gnu.org/manual/devel/en/h…

One use case is to delegate the choice of channel commits to pull to a continuous integration server.

Another one is, within a development team, to delegate that choice to one person within the team, so that everyone downloads a “known-good” set of channels.

Poking around (guix packages), it looks pretty straightforward to support SRI hashes ;)

When filling stuff like (sha256 (base32 "1avf4x8skxbqrjp5j2qr9sp5vlf8jkw2i5bdn51fl3cxx3fsxchx")) in a source definition, Guix actually uses a macro to transform the hash string into a bytevector at compile time. So how the hash is represented in the code doesn't matter internally, and it's quite easy to add another representation.

#guix

At least the issue is addressed for kernel modules. Those in NVIDIA drivers should be working as expected now.

Like any good admin, I chose Friday evening to deploy Cuirass 1.3.6 on ci.guix.gnu.org and pulls.ci.guix.gnu.org 👇

codeberg.org/guix/cuirass/src/…

It’s primarily a bug-fix release but it has a couple of noteworthy improvements made by my partners in crime at Inria, @shepherd and @vivien_kraus .

#Guix

Anybody on here using Guix system on a Vultr VPS? Both tries I made today to upload the Guix System ISO just hung with 'pending' message.

(I am aware of this post from Thomas Ieong ieong.ovh/posts/guix-vultr/)

Are there VPS providers where Guix works especially smoothly?

#Guix #VPS #Vultr

Didn't touch it much during the period, so I'm just making it public in the current form. I think I'll need to have a deeper understanding of contract systems in general to improve it.

The code shows how to attach contract to Guix records and here's an example record definition, see also the attached screenshot for its error message.

#guix

The pretty amazing feat that comes with GNOME 49 in #Guix is the gnome-session replacement implemented as a layer above the 🐑 Shepherd:
gitlab.gnome.org/noe/gnome-ses…

Kudos to @baleine for pulling it off!

It successfully disentangles this part of GNOME from systemd, and it’s a creative use of the Shepherd!

Announcing Guile Knots!

It's been around for a while, but I thought I'd try and do some publicity.

The blog post has more details but let me know if you have any thoughts or questions!

#guile #fibers #guix

It turns out that G-expressions don't handle references in vectors created using the read syntax (for example, #(1 2 3))
codeberg.org/guix/guix/pulls/1…

This will be useful if you have extensive usage of serializers like guile-json, which use vectors to represent arrays.

#guix system with systemd

Currently it is only a demo and can be started via `guix system vm`.

Why do this? Because it's fun.

Introducing the mega Nonguix :P
ultrarare.space/en/posts/manag…

Here's English version! Updated for nix-shell-wrapper interface change and the new with-nix-profile. Added a new section for extra setups to workaround issues introduced by different packaging practices. Let me know if there're more of them.

Probably I'll translate it into en at some time. For now I just tell you what's new in the post:

  guix package --search-paths \
       -p /run/current-system/profile \
       -p /nix/store/csj09rkmgyjc9y7wzvscla2lavhwc0rg-readest-0.11.1

  ...
  export PATH="/run/current-system/profile/bin:/run/current-system/profile/sbin:/nix/store/csj09rkmgyjc9y7wzvscla2lavhwc0rg-readest-0.11.1/bin"
  export XDG_DATA_DIRS="/run/current-system/profile/share:/nix/store/csj09rkmgyjc9y7wzvscla2lavhwc0rg-readest-0.11.1/share"
  export XCURSOR_PATH="/run/current-system/profile/share/icons:/nix/store/csj09rkmgyjc9y7wzvscla2lavhwc0rg-readest-0.11.1/share/icons"

♲ @hako@boiledscript.com:

Tweaked the interface a bit and added docstring. Here's code for nix-shell-wrapper and nix-shell-wrapper->package:
codeberg.org/hako/Rosenthal/sr…

Too many backslashes are used in the docstring, duplicating the examples here as well:

(nix-shell-wrapper "cowsay"
  '("github:NixOS/nixpkgs/nixos-26.05#coreutils"
    "github:NixOS/nixpkgs/nixos-26.05#cowsay")
  #:run-command '("env" "LANG=C.UTF-8" "cowsay" "hello"))

(nix-shell-wrapper "python-with-numpy"
  "with (import (builtins.getFlake \"github:NixOS/nixpkgs/nixos-26.05\") {}); python3.withPackages (ps: [ps.numpy])"
  #:expression? #t
  #:run-command '("python"))

#guix

用 GNU Guix 管理 Nix 包

^{Ultra Rare Space}

Added a with-nix-profile macro. It can be used in package declaration of Guix System and Guix Home, transforming nix-shell-wrapper into packages and collecting Nix packages from them.

With the collected Nix packages, an additional build-nix-profile command is provided to build and link the resulted profile to the specified path, also registering GC root.

What's left is to write services to execute this build-nix-profile command and extend search paths ;)

To avoid loading incompatible libraries from the other distribution and crashing programs, like what may happen when using Guix and Nix on foreign distros, the constructed Nix profile won't contain executables and commands are provided by the nix shell wrappers.

See also the first few lists in codeberg.org/hako/Rosenthal/sr… and let me know what are missing.

#guix #nix

I didn't fully understand nix shell, so here's improved nix-shell-wrapper interface (haven't pushed yet). Probably interesting to Nix folks as well :)

Collection of reproductible #eda #podman images for electronic design development, using #guix, classified by domain (#asic, #fpga, #synthesis, etc.)

podman run -it --rm --network=host -e DISPLAY -v "$PWD":"$PWD" -w "$PWD" -e HOME guix-kicad:0.1 kicad

Similar commands exist for #yosys, #ghdl, etc.

Tweaked the interface a bit and added docstring. Here's code for nix-shell-wrapper and nix-shell-wrapper->package:

codeberg.org/hako/Rosenthal/sr…

Too many backslashes are used in the docstring, duplicating the examples here as well:

(nix-shell-wrapper "cowsay"
  '("github:NixOS/nixpkgs/nixos-26.05#coreutils"
    "github:NixOS/nixpkgs/nixos-26.05#cowsay")
  #:run-command '("env" "LANG=C.UTF-8" "cowsay" "hello"))

(nix-shell-wrapper "python-with-numpy"
  "with (import (builtins.getFlake \"github:NixOS/nixpkgs/nixos-26.05\") {}); python3.withPackages (ps: [ps.numpy])"
  #:expression? #t
  #:run-command '("python"))

Here's improved example on constructing the Nix command, with a Scheme procedure for nix shell (more flexible than nix run and more similar to guix shell) wrappers.

#guix

There're chances that Guix misses service packages you want to use, and you can actually deploy your services with them from other sources, before the packages are properly packaged.

Besides the oci-service-type, Nixpkgs is also a good fit. The nix run command is similiar to guix time-machine + guix shell so you can have version-pinning as well.

Here's a rough example for the setup.

#guix #nixpkgs

Hey, everyone. I want to spend the next few weeks learning @guix and installing it as a replacement for Debian. The learning curve looks daunting. Where do I start?

I want to do it on real hardware and I have a spare laptop. Sadly @daviwil's nice tutorials appear outdated...?

What I have: an ambition for software freedom and a love of Lisp. What I need: an understanding of the packaging model and (sadly) support for non-free hardware.

Point me to a recent .iso? Point me to a good explainer for noobs? Thanks!

#askfedi #Guix

Hey #Guix!

Now `guix pull` and `guix time-machine` supports Git symref. And?

It allows to easily have unmerged Pull-Request.

Consider the fictive PR 567 improving package foo.
And such CI processed this PR with the evaluation 1234.

Then

guix time-machine \
-C guix.bordeaux.inria.fr/eval/12… \
-- shell foo bar

where channels.scm file points to refs/pull/567/head.

Done! 🤩
