A lot of fetchers from Nix's own `libfetchers` also provide the
information that `lib.trivial` aims to expose with
`version`/`versionSuffix`/`revision`. In fact you don't even need a
`nixpkgs` channel to get a proper version suffix because of that!
Unfortunately this isn't used currently. When using the
nixpkgs flake, but not `nixpkgs.lib.nixosSystem` to build a NixOS
configuration, the version will always be `YY.MMpre-git`. One example is
e.g. `colmena` which evaluates configurations via
`import (npkgs.path + "/nixos/lib/eval-config.nix")`.
This patch ensures that the version suffix (i.e. the normalized last
modified date + git revision) is correctly exposed in `lib.trivial`.
Additionally, the change is injected into the following locations:
* `lib`: with that, something like
$ nix eval nixpkgs#lib.trivial.version
23.05.20230921.cf8bf79
is working fine (i.e. rather than `23.05pre-git`).
* `legacyPackages` to make sure that e.g. `legacyPackages.<system>.nixos`
has correct version info. This also applies to everything else using
`pkgs.lib.trivial` for that purpose.
* `overlays.default` which can be applied to a `nixpkgs` and changes the
previous `pkgs.lib` from said `nixpkgs` to also contain the correct
`version`/`revision`/etc..
This is useful for people using `nixpkgs` as flake input, but
importing it manually with
import inputs.nixpkgs { }

Other Project Repositories
The sources of all official Nix-related projects are in the NixOS organization on GitHub. Here are some of the main ones:
- Nix - the purely functional package manager
- NixOps - the tool to remotely deploy NixOS machines
- nixos-hardware - NixOS profiles to optimize settings for different hardware
- Nix RFCs - the formal process for making substantial changes to the community
- NixOS homepage - the NixOS.org website
- hydra - our continuous integration system
- NixOS Artwork - NixOS artwork
Continuous Integration and Distribution
Nixpkgs and NixOS are built and tested by our continuous integration system, Hydra.
- Continuous package builds for unstable/master
- Continuous package builds for the NixOS 23.11 release
- Tests for unstable/master
- Tests for the NixOS 23.11 release
Artifacts successfully built with Hydra are published to cache at https://cache.nixos.org/. When successful build and test criteria are met, the Nixpkgs expressions are distributed via Nix channels.
Contributing
Nixpkgs is among the most active projects on GitHub. While thousands of open issues and pull requests might seem a lot at first, it helps consider it in the context of the scope of the project. Nixpkgs describes how to build tens of thousands of pieces of software and implements a Linux distribution. The GitHub Insights page gives a sense of the project activity.
Community contributions are always welcome through GitHub Issues and Pull Requests.
For more information about contributing to the project, please visit the contributing page.
Donations
The infrastructure for NixOS and related projects is maintained by a nonprofit organization, the NixOS Foundation. To ensure the continuity and expansion of the NixOS infrastructure, we are looking for donations to our organization.
You can donate to the NixOS foundation through SEPA bank transfers or by using Open Collective:
