Eelco Dolstra 3d0e81051f Fix lock file generation 
Before:

   "requires": {
        "nixpkgs": {
            "uri": "nixpkgs"
        }
    },

After:

    "requires": {
        "nixpkgs": {
            "uri": "github:edolstra/nixpkgs/f10e8a02eb7fa2b4a070f30cf87f4efcc7f3186d"
        }
    },

Eelco Dolstra 8c4e759efd updateLockFile(): Make sure Git can see flake.lock 2019-04-16 15:11:17 +02:00
Eelco Dolstra 60834492ae Update lock files from InstallableFlake::toValue() 
This ensures that the lock file is updated *before* evaluating it, and
that it gets updated for any nix command, not just 'nix build'.

Also, while computing the lock file, allow arbitrary registry lookups,
not just at top-level.

Also, improve some error messages slightly.

Eelco Dolstra ee1254d4f5 nix: Add --impure as a shorter alias of --no-pure-eval 2019-04-08 23:19:19 +02:00
Eelco Dolstra 6a4c7fb975 Add path flakeref variant 
Unlike file://<path>, this allows the path to be a dirty Git tree, so

  nix build /path/to/flake:attr

is a convenient way to test building a local flake.

Eelco Dolstra 154244adc6 nix: New installables syntax 
The general syntax for an installable is now
<flakeref>:<attrpath>. The attrpath is relative to the flake's
'provides.packages' or 'provides' if the former doesn't yield a
result. E.g.

  $ nix build nixpkgs:hello

is equivalent to

  $ nix build nixpkgs:packages.hello

Also, '<flakeref>:' can be omitted, in which case it defaults to
'nixpkgs', e.g.

  $ nix build hello

archive.

nix: Add --flake flag 
This allows using an arbitrary "provides" attribute from the specified
flake. For example:

  nix build --flake nixpkgs packages.hello

(Maybe provides.packages should be used for consistency...)

Enforce use of immutable flakes in pure mode 
... plus a temporary hack to allow impure flakes at top-level for the
default installation source.

nix: Enable pure mode by default 
We want to encourage a brave new world of hermetic evaluation for
source-level reproducibility, so flakes should not poke around in the
filesystem outside of their explicit dependencies.

Note that the default installation source remains impure in that it
can refer to mutable flakes, so "nix build nixpkgs.hello" still works
(and fetches the latest nixpkgs, unless it has been pinned by the
user).

A problem with pure evaluation is that builtins.currentSystem is
unavailable. For the moment, I've hard-coded "x86_64-linux" in the
nixpkgs flake. Eventually, "system" should be a flake function
argument.
