Until now we had the problem that the matrix team wasn't pinged on
element changes because the version data is in a JSON and the position
of the `version`-attribute wrongly pointed to
`element-{web,desktop}.nix`:
nix-instantiate -E 'with import ./. {}; builtins.unsafeGetAttrPos "version" element-web' --eval
{ column = 22; file = "/home/ma27/Projects/nixpkgs/pkgs/applications/networking/instant-messengers/element/element-web.nix"; line = 24; }
This is a problem because ofborg checks if modified file is part of a
derivation that got changed in a PR. I.e. only pings for element's
maintainers would be added to an element update PR if `pin.json` (which
gets modified in that case) would be recognized as file being a part of
the changed derivations (element-web/element-desktop)[1]
However, JSON imports don't propagate attribute positions (I don't know
how one would that sanely implement btw), so I decided to change
`pin.json` to a `pin.nix` and merge the relevant contents into
element-web/element-desktop.
This is kinda hacky, but as a maintainer I'd like to get modified if
somebody touches element so I can review & merge that.
With this change the position detection works fine now:
{ column = 3; file = "/home/ma27/Projects/nixpkgs/pkgs/applications/networking/instant-messengers/element/pin.nix"; line = 2; }

Nixpkgs is a collection of over 80,000 software packages that can be installed with the Nix package manager. It also implements NixOS, a purely-functional Linux distribution.

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 22.11 release
- Tests for unstable/master
- Tests for the NixOS 22.11 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. When pull requests are made, our tooling automation bot, OfBorg will perform various checks to help ensure expression quality.
The Nixpkgs maintainers are people who have assigned themselves to maintain specific individual packages. We encourage people who care about a package to assign themselves as a maintainer. When a pull request is made against a package, OfBorg will notify the appropriate maintainer(s). The Nixpkgs committers are people who have been given permission to merge.
Most contributions are based on and merged into these branches:
masteris the main branch where all small contributions gostagingis branched from master, changes that have a big impact on Hydra builds go to this branchstaging-nextis branched from staging and only fixes to stabilize and security fixes with a big impact on Hydra builds should be contributed to this branch. This branch is merged into master when deemed of sufficiently high quality

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:
