Make flake input fetching lazy 
As long as the flake input is locked, it is now only fetched when it
is evaluated (e.g. "nixpkgs" is fetched when
"inputs.nixpkgs.<something>" is evaluated).

This required adding an "id" attribute to the members of "inputs" in
lockfiles, e.g.

  "inputs": {
    "nixpkgs/release-19.03": {
      "id": "nixpkgs",
      "inputs": {},
      "narHash": "sha256-eYtxncIMFVmOHaHBtTdPGcs/AnJqKqA6tHCm0UmPYQU=",
      "nonFlakeInputs": {},
      "uri": "github:edolstra/nixpkgs/e9d5882bb861dc48f8d46960e7c820efdbe8f9c1"
    }
  }

because the flake ID needs to be known beforehand to construct the
"inputs" attrset.

Fixes #2913.

shell.nix: Use clang by default 
Clang compiles faster (121s vs 156s for GCC 7) so it's a bit nicer for
development.

Merge pull request #2909 from NixOS/flake-apps 
Add 'nix app' command
 2019-06-03 09:34:36 +02:00

Add 'nix app' command 
This is like 'nix run', except that the command to execute is defined
in a flake output, e.g.

  defaultApp = {
    type = "app";
    program = "${packages.blender_2_80}/bin/blender";
  };

Thus you can do

  $ nix app blender-bin

to start Blender from the 'blender-bin' flake.

In the future, we can extend this with sandboxing. (For example we
would want to be able to specify that Blender should not have network
access by default and should only have access to certain paths in the
user's home directory.)

Automatically determine subdir for path flakes 
This means that in a flake in a subdirectory of a Git repo, you can
now do

  $ nix build

  $ nix build ../..?dir=foo/bar

Allow bare flakerefs as installables 
So now

works and builds the default package from that flake. You don't need
to add a colon at the end anymore.

Add date of last commit to SourceInfo 
This is primarily useful for version string generation, where we need
a monotonically increasing number. The revcount is the preferred thing
to use, but isn't available for GitHub flakes (since it requires
fetching the entire history). The last commit timestamp OTOH can be
extracted from GitHub tarballs.
