* treewide: Format all Nix filesSilvan Mosberger2025-04-011-184/+538
| | | | | | | | | | | | | | | | | | | | | | Format all Nix files using the officially approved formatter, making the CI check introduced in the previous commit succeed: nix-build ci -A fmt.check This is the next step of the of the [implementation](https://github.com/NixOS/nixfmt/issues/153) of the accepted [RFC 166](https://github.com/NixOS/rfcs/pull/166). This commit will lead to merge conflicts for a number of PRs, up to an estimated ~1100 (~33%) among the PRs with activity in the past 2 months, but that should be lower than what it would be without the previous [partial treewide format](https://github.com/NixOS/nixpkgs/pull/322537). Merge conflicts caused by this commit can now automatically be resolved while rebasing using the [auto-rebase script](https://github.com/NixOS/nixpkgs/tree/8616af08d915377bd930395f3b700a0e93d08728/maintainers/scripts/auto-rebase). If you run into any problems regarding any of this, please reach out to the [formatting team](https://nixos.org/community/teams/formatting/) by pinging @NixOS/nix-formatting.

| * lib: Discourage use of extendRobert Hensing2025-01-231-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It creates interoperability issues that can not be reconciled by `lib` or maintainers of projects that use the Nixpkgs library. Occasionally, end users may be able to solve the problems they run into, but most are not prepared to deal with this set of problems, nor should they be. Typical conflict: - User wants to propagate their own lib, because it has some function they like to use throughout their projects - Project maintainer requires the project's lib to be used No sane language uses a single namespace for combining all the things. (Arguably not even C with its extensive use of prefixing) Meanwhile, in Nix, all symbols are first class variables. We don't even have the concept of a global top-level namespace to pour everything into. With `lib` you can try to approximate that, I get the appeal of its apparent simplicity, but since `lib` can't be global, we just don't even get that apparent simplicity. I apologize for not offering concrete solutions to this in the text. The manuals are limited to reference documentation. Alternatives - of which we have multiple - are best provided in task-oriented documentation, e.g. nix.dev.

| | | | | | | | `strings.trim` returns a copy of the string with all leading and trailing whitespace removed. `strings.trimWith` does the same thing, but calling code can decide whether to trim the start and/or end of the string.

| * | lib.network: ipv6 parser from stringwoojiq2024-06-291-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add a library function to parse and validate an IPv6 address from a string. It can parse the first two versions of an IPv6 address according to https://datatracker.ietf.org/doc/html/rfc4291#section-2.2. The third form "x:x:x:x:x:x.d.d.d.d" is not yet implemented. Optionally parser can accept prefix length (128 is default). Add shell script network.sh to test IPv6 parser functionality.
