Install obelisk with flake

[MohsenNz]

I'm newbie in obelisk and nix, but I'm using nix (home-manager) with flake in my Ubuntu. How can I install obelisk with that?

Here's a simple flake with a dev shell that contains Obelisk:

{
  nixConfig.binaryCaches = [ "https://nixcache.reflex-frp.org" ];
  nixConfig.binaryCachePublicKeys = [ "ryantrinkle.com-1:JJiAKaRv9mWgpVAz8dwewnZe0AzzEAzPkagE9SP5NWI=" ];

  inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
  inputs.flake-utils.url = "github:numtide/flake-utils";
  inputs.obelisk = {
    url = "github:obsidiansystems/obelisk";
    flake = false;
  };

  outputs = inputs: inputs.flake-utils.lib.eachDefaultSystem (system:
    let
      pkgs = import inputs.nixpkgs { inherit system; };
      obelisk = pkgs.callPackage inputs.obelisk {
        inherit system;
        terms.security.acme.acceptTerms = true;
      };
    in
    {
      inherit obelisk;
      devShells.default = pkgs.mkShell {
        nativeBuildInputs = [
          obelisk.command
        ];
      };
    });
}

I got this error:

error: flake 'path:/home/mohsen/dev/test' does not provide attribute 'packages.x86_64-linux.default' or 'defaultPackage.x86_64-linux'

I have no idea about fixing it. home/mohsen/dev/test is the directory contains the flake.nix

Ok I did wrong command, nix shell, Now doing nix develop give this error:

λ nix develop
error (ignored): error: end of string reached

It looks partial duplicate of #854. Try to add --impure option.

BTW, using this method started building a large number of dependencies such as cabal, glib, llvm, etc. and wasted several hours. Does anyone know how to import the cache?

https://github.com/obsidiansystems/obelisk/pull/1096 this should fix it: it fixes the ~/.gitconfig issue and one more you'd hit afterwards.

Leave a comment if it still doesn't work.
