Building hoogle environments with an empty list of packages threw a built-time error. This was particularly confusing when giving e.g. `(hps: [hps.Cabal])` which, since `Cabal` is set to `null` (because it’s a distribution package), would have lead to the same error as an empty list. It was not useful to throw an error at all, because sometimes one only wants to build an environment for the distribution packages; also the default value for packages wasn’t even a valid value, so it is removed.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-16.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-16.09
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
