This makes all Nix files addressable from root by file path.
For instance, if a file is located in //foo/bar:baz.nix containing:
{ pkgs, ... }:
pkgs.stdenv.mkDerivation {
pname = "foo";
# ...
}
You can then do:
nix-build -A foo.bar.baz
All nix files loaded this way must be a function taking a 'config'
attrset - see nix/readTree.nix for more information. Currently the
config attrset contains the following fields:
- hscloud: the root of the hscloud repository itself, which allows
for traversal via readTree (eg. hscloud.foo.bar.baz)
- pkgs: nixpkgs
- pkgsSrc: nixpkgs souce/channel, useful to load NixOS modules.
- lib, stdenv: lib and stdenv from pkgs.
