The setup is based on bazel 5,6,7 in nixpkgs but is significantly different codeline-wise. There's a bit less patching, all patches are via patch files and other small tweaks. ## Bazel 8 build With 8.4.1 bazel dist archive is enough for air-gapped build removing the need for FODs or `src-deps.json`, and in turn we no longer need existing `bazel` binary to bootstrap the build. `enableNixHacks` patch is removed, `bazel-examples` repo is used as `passthru.tests` (cpp, java, rust) via new `bazel_8/build-support` helpers. `sed` patches are converted to patch files, overall amount of patching is reduced, if there'd be need for more it can be added with links to upstream issues or patches, ideally with a regression `passthru.tests` item. Amount of patching may potentially be reduced further, this needs more feedback using this. Overall using Bazel on NixOS remains tricky, for non-packaged repos it may still be most practical to use FHS + extra hacks and patches, maybe even straight up using Bazelisk and upstream pre-built binaries in FHS. ## buildBazelPackage support `pkgs/build-support/build-bazel-package/default.nix` is fairly big with a set of tweaks that may not be necessary with recent Bazel or may have better alternatives. More work is needed to figure out compatibility with `bazel_8` or other things to unify with `bazel_8` helpers. ## bazel_8/build-support Here are fairly minimalistic helpers to aid building Bazel packages using Bazel 8 features. For now only testes on `bazel-examples` repo. `patching.nix`: just a helper to inject patches into Bazel external dependencies `bazelDerivation`: helps to compose Bazel commandline and consume `repository_cache`, `vendor_dir`, `registry` all related to external dependencies management `bazelPackage`: two-stage derivation similar to `buildBazelPackage`, having options for `repository_cache` (pure fetches) or `vendor_dir` (unpacked fetches, further patchable)
Nixpkgs is a collection of over 120,000 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

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 25.05 release
- Tests for unstable/master
- Tests for the NixOS 25.05 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.
