For many, overlays, and fixed-point functions as underlying concept, are hard to gasp in #Nix.

I found the documentation to be actually quite good in this case, checkout the function docs of fix and extends (and read in this order). Both have great examples/steps that guide you through, which was really helpful to me.

#NixOS #nixpkgs

Any way to trigger a command in #NixOnDroid with the press of a button on the home screen?

For #termux there is the widget app but it doesn't appear to work with #nix-on-droid.

I really don't want to have to install and maintain #gitAnnex using some install script and some prebuilt global FHS binaries when I could simply get it from #nixpkgs.

Looks like #NixOS is still growing 🤯 Commit statistics on #nixpkgs

The more I look into other packaging systems as #nixpkgs the more I am horrified. They call themselves a distro but have no good way to handle a go repository without a vendor directory.

My current mood is: do not use python3 when building Python packages, use the generic python parameter instead

#nix #nixpkgs

Fixed my overlays, but I think the error message is very #nixpkgs specific? If you simply use something like pkgs.python3.pkgs.buildPythonPackage, you don't have a "generic python parameter" ...

Aux Lib is, by and large, a rewrite and downsizing of Nixpkgs' `lib`. Though, there are things that have been removed, changed, or added. Still, we would not be able to release this today without the work of all the #Nixpkgs contributors.

Nice, lib.packagesFromDirectoryRecursive now supports nested scopes!

packagesFromDirectoryRecursive transforms a directory tree of packages into a nested attribute set of derivations. You can use it to manage a package set in a similar way to by-name in nixpkgs (without the sharding part). The package files in tree must be suitable for callPackage.

Subdirectories in the tree result in nested attribute sets. In the following example, packages d, e and f will be in a nested attribute set called my-namespace.

my-packages
├── a.nix
├── b.nix
├── c
│  ├── my-extra-feature.patch
│  ├── package.nix
│  └── support-definitions.nix
└── my-namespace
   ├── d.nix
   ├── e.nix
   └── f
      └── package.nix

Previously, this would only use one scope (my-packages), so e could only depend on d as my-packages.d. With the introduction of nested scopes, e can refer to d within the same scope directly.

I though it had been a while without any #NixOS drama, but of course the universe provides.

Guess what, telemetry in #devenv is coming back. Again, it's Opt-Out, not Opt-In.
The difference: this time that work is sponsored by the NixOS Foundation.

Brought to you by @domenkozar of course.

Further, I opened a PR to add keep-sorted to the nixpkgs CI. keep-sorted is a language-agnostic formatter that sorts lines between two markers in a larger file. It will help us to get some order in the large top-level files like all-packages.nix!

#Nix #nixpkgs #golang #vendoring

#OceanSprint 2025 is over, it was an great experience!

I mostly worked on gobuild.nix, a next-generation builder for Go in nixpkgs. gobuild.nix removes vendoring for Go packages in nixpkgs, modeling the full dependency graph in Nix. Each module dependency will be its own derivation, including build cache on a module level.

During the sprint, I moved gobuild.nix from linking dependency source into a vendor directory to providing a local directory that can be used as GOPROXY. This is both more versatile and simple.

Together with @britter I started implementing a code generation tool that will help to package the large number of packages that will be part of the Go dependencies package set. The tool generates the Nix code for these packages, including the FOD hashes.

#Nix #nixpkgs #golang #vendoring

Who needs pigs to fly? I think that the end times will be marked by an occasion where two #NixOS or #nixpkgs users agree on the correct way to build a FOSS project.

"use devshell"
"use flake"
"use this other flake thing"
"just use upstream nixpkgs"
"upstream nixpkgs is slow, let's use this fhsENV thing"
"use flakeutils, it's really handy"
"flakeutils that everyone uses is a waste of time, just use nix directly"
"nix2 solved all of our problems, flakes just add unnecessary complexity"
"structure the flake like this"

This is a serious proposal, we should actually ban and denounce determinate systems now.

Want to help out Nixpkgs but don't know what to do? I compiled a list of still failing packages due to switching to GCC-14 in stdenv a while back. GCC changed some warning to errors in this version and lots of especially older projects fail to build now.

Plenty of examples of the fix already in Nixpkgs, ideal for first time contributors.

The latest set of GRUB2 #security vulnerabilities from mid-February https://lists.gnu.org/archive/html/grub-devel/2025-02/msg00024.html requires **79** patches, along with some adjustments, to be applied to the latest stable tarball without breaking #NixOS tests.

This does not make life easy for downstream consumers.

If other distro maintainers want to take a look, I have isolated the patches so you don't have to deal with Nix: https://gist.github.com/LeSuisse/34059dd08bddc9b509097d42d3ca9109

🚀 New Blog Post! 🚀

I've been working on optimizing Gradle build support in nixpkgs! In my latest post, I take a deep dive into how it currently works, the limitations of the existing approach, and an optimization that improves efficiency and maintainability.

Check it out here: https://britter.dev/blog/2025/02/19/nixpkgs-gradle-optimization/

I’d love to hear your thoughts! Also, if your team needs Gradle or NixOS consulting, I’d be happy to help. 😊

Domen, creator of devenv, recently added telemetry to his devenv thing, as part of adding AI to the product, and when nixpkgs contributors removed the telemetry, he reverted the change, with a self merge, without a fucking review even.

https://github.com/NixOS/nixpkgs/pull/381981

This is a clear conflict of interest. We need to stop this from happening in the NixOS organization, corpos need to have some respect for users.

So we now have commercial actors in #nixpkgs who can just push their own commercial agenda be decree.

@emilychwiggy I don't pin the extensions. Missing executables can generally provided with the direnv extension.

#Nixpkgs doesn't provide a mature vscode or vscodium distribution yet. Needs automated tests and more maintainers, I would guess.

I wonder if I could configure my Nix binary cache to do on-demand cross-compilation of packages so this poor ancient laptop doesn't cook itself every time I rebuild....

#Nix #NixPkgs

After some months of work, I got the legacy `buildGoPackage` builder removed from #nixpkgs. Most packages using the legacy builder were migrated to `buildGoModule`. Now we have less maintenance burden and thus the chance to work on something new!

Shortly after the branch off for the upcoming release of NixOS 24.11, there was quite a drop in the share of Go package sources that are vulnerable, compared to the last scan 3 months ago.

Report with all vulnerable packages can be found here: https://github.com/katexochen/govulncheck-nixpkgs

#nixpkgs issue for this is https://github.com/NixOS/nixpkgs/issues/84312

TIL: `git archive` is used by GitHub and other forges to create an archive of a repo to download. git can do unexpected thing when creating such archive, like variable substitution using the `export-subst` feature. So even if a commit is immutable, you can still download different content if a ref or tag changed.

https://git-scm.com/docs/git-archive/2.46.0#Documentation/git-archive.txt-export-subst

Example: https://github.com/smallstep/cli/blob/master/.VERSION

That's a real problem in context of reproducible builds (or just source-pinning in general).

#ReproducibleBuilds #nixpkgs #nix #git #github

So I ran the script that @kees adapted from @bagder 's initial concept on the older×biggest repo I still make use of.

(Side-note, It would be interesting to have an AST-aware equivalent that can guesstimate the age of the constructs, rather than the age the "source" stringy-based serialization, especially since it's likely some changes refreshed some line's age, but actually only changed part of its semantics, or nothing at all.)

I ran it on the release tags (in other words, the initial point in time a numbered release was marked stable).

It took a surprisingly long amount of time, but I did not change the implementation. Maybe there's some accidentally quadratic operation that could be made faster... But also this is a legitimately big git repo, and maybe the hours it spent on the last few tags were legitimate.

Anyways, #Nixpkgs and #NixOS peeps might like that.

There will be a Go meetup @ NixCon on Sunday, 11:00. Join us in discussing Go in nixpkgs, buildGoModule and community projects around Go and Nix. Check out the pad and feel free to add topics: https://pad.fluxfingers.net/E6VPRRYGQ2-0KtAjj_zKGA?both

Iunno how to use social media or Mastodon, but I've been meaning to give this a try for awhile. #Introduction :

- 24yo trans CS student in Leipzig, Germany
- Life for me revolves around tech. Preferably Linux, old computers and sound chips.
- #Programming since 6th grade. Used Lua, Object Pascal, C, C++, and many more over the years. Currently C# and Assembly for uni.
- #NixOS user & #Nixpkgs contributor since 2018, Linux user since 2015…-ish?
- Current project: Slowly getting #Lomiri submitted into #Nixpkgs / #NixOS, + dealing with uni.

Iunno what I'll post on here or expect to get out of this yet. Prolly complaining about programming stuff. Maybe finding like-minded and/or local people? We'll see I guess.

Hello World.
