Add repoOverrides

[bb010g]

Includes my NUR repo, the neXromancers NUR repo, and an argument to allow for overrides of repos on invocation. Pretty straightforward, and here's how I used it to work on packaging these smoothly:

repoOverrides = {
  bb010g = { type = "path"; url = ~/nix/nur-bb010g; };
  nexromancers = { type = "path"; url = ~/nix/nur-nexromancers; };
}

Yes, you could do this by symlinking in directories to the proper places in <NUR/repos>, but this feels a lot more idiomatic to me, also supports testing non-local repositories, and does not require a local NUR clone.

• I ran nur/format-manifest.py after updating repos.json (We will use the same script in travis ci to make sure we keep the format consistent)
• By including this repository in NUR I give permission to license the
  content under the MIT license.

The license in hacksaw is incorrect: https://travis-ci.com/nix-community/NUR/builds/95325314#L760

[bb010g]

Fixed.

I cherry-picked your repositories to master
I want to have a closer look at repoOverrides soonish

Sounds good. Simplified this down to just the one commit.

[bb010g]

Bump?

@bb010g see #111
Just install NUR as an overlay and add override overlay:

self: super: {
  nur = super.nur // {
    repos = super.nur.repos // {
      bb010g = import ~/nix/nur-bb010g self;
      nexromancers = import ~/nix/nur-nexromancers self;
    };
  };
}

Just make sure this overlay is loaded after NUR one, then all overrides will work correctly.

@danbst right, but this looks complex an easier way as proposed by @bb010g is still worth pursuing.

[danbst]

I hope NixOS/nixpkgs#54266 will get more love, then NUR as overlay will allow this:

self: super: {
  nur.repos.bb010g = import ~/nix/nur-bb010g self;
  nur.repos.nexromancers = import ~/nix/nur-nexromancers self;

  # in case we want to replace bit-by-bit, including removals
  nur.repos._merge.bb010g = false;
  nur.repos._merge.nexromancers = false;
}

I'm not opposing to PR, just proposed another way to solve the problem (without "symlinking in directories to the proper places in <NUR/repos>")

[bb010g]

This allows you to continue using packageOverrides nicely, which is the recommended NUR installation method.

@bb010g can you take a look at: #112
?

Thanks! Feature got merged with #112
