[slaier]

Like sops --extract '', get the plain file instead of an single key.
Fixes: #120

I link this here so that it won't be missed : https://github.com/slaier/sops-nix/pull/1

Any reason this was dropped?

I think @slaier simply removed its own fork without having this PR in mind, as some months have passed in between.

But it is still relevant and should be reopen.

Just as a stop gap, it can be applied like this in a sops-nix overrideAttrs :

patches = [
  (fetchpatch {
    url = "https://github.com/Mic92/sops-nix/pull/338.patch";
    hash = lib.fakeHash;
  })
];

Oops sorry, it seems code has diverged too much to apply the patch as is. I can take a look to revive it.
