The file `flake.nix` provides a standardized way to provide [[Zettelkast/Index/Nix]] artifacts. It's like a package manager for [[Zettelkast/Index/Nix]]. A flake can be dependent on other Flakes and it's possible to pin dependencies to exact revisions by using a `flake.lock` file. - -Nix flake evaluation is hermetic, meaning that it produces the same result wherever it's built.k - -The feature can be enabled in `~/.config/nix/nix.conf`: - -``` -experimental-features = nix-command flakes -``` - -To initialize in a repo: `nix flake init`. - -In flakes dependencies have to be specified explicitly and MUST be locked to specific versions therefore it's no longer allowed to use the nixpkgs found in `NIX_PATH` by referencing it like `<nixpkgs>`. - -Output of a Flake is an arbitrary [[Zettelkast/Index/Nix]] value such as a package, [[NixOS]] module or library function. -Commands `nix build` and `nix shell` will build the output `packages.<system>.default` unless we specify another output, for example: `nix shell .#checks.aarch64-linux.build`. - ---- -[Flakes Wiki](https://nixos.wiki/wiki/Flakes)
