If Nixpkgs ever goes out of date in these examples, just run yae update!
This example showcases adding the Nixpkgs unstable branch as a Yae source,
consuming it within an example flake, and mirroring the hello package from
Nixpkgs as a flake output.
Note that the flake has no inputs. This is because Yae directly manages the Nixpkgs source.
This example is extremely useful and is intended be adapted to suite the specific needs of flake-less Nix configurations, like classic Nix shells and flake-less system configurations.
This example is functionally identical to the Nixpkgs example, with the exception
that it utilises builtins.currentSystem to populate the nixpkgs.system
attribute, requiring the --impure command-line flag.
This example is purely for the sake of example, since in a real-world scenario,
you'd likely use something similar to flake-utils
for multi-system output management and populating the nixpkgs.system attribute.
