Is there a way to determine if you're in a nix shell with the new flakes `nix shell` command?

      function w
        if set -q with_pkgs
          set with_pkgs ", $with_pkgs"
        end
        set -lx with_pkgs "$argv$with_pkgs"
        IN_NIX_SHELL=impure name="with: $with_pkgs" \
          ${config.nix.package}/bin/nix shell nixpkgs#$argv
      end

function w
  if set -q with_pkgs
    set with_pkgs ", $with_pkgs"
  end
  set -lx with_pkgs "$argv$with_pkgs"
  IN_NIX_SHELL=impure name="with: $with_pkgs" \
    ${config.nix.package}/bin/nix shell nixpkgs#$argv
end

Hi there :) I just have a quick question, is there a way to "keep" a broken nix build ? As was possible before using the -K flag IIRC?

In reply to @andi:kack.it
Why is nix eval --raw .#checks.x86_64-linux.my-build not giving me a drv path but a build result instead? Not passing --raw yields in fetchurl complaining about a meta parameter...

But how is that different from `nox build` then?

I’ve been trying to improve the filterSource,path,etc stuff. I’ve lost track of exactly where we are. Can you try on latest? Another approach is to use an “external flake” where the flake is acting on a remote input source code. This is another way to cut the impact of white space.

Whats the equivalent of nix-instantiate for flakes? I want to debug a build and looking at the derivation is a common first step for me. I can't find a way to get the drvPath without accessing e.g. the attribute.
