Commit 8204a49 disables channels which breaks NIX_PATH functionality due to NixOS/nix#9574.

This adds a workaround.

Does this issue occur due to disabling channel or it is some issue on the nixos's part?

It's a problem with the Nix command line tool

OMG gotcha!

@JManch I want to ask one thing, why do we need to specially set nix shell, nix profile or nix-env to use flake inputs nixpkgs version? Shouldn't it be by default? Is there any issue tracking of this or will it be implemented to do that by default or will it not?

This whole code is for that right?

nix = let
    flakeInputs = lib.filterAttrs (_: lib.isType "flake") inputs;
  in {
    settings = {
      # Enable flakes and new 'nix' command
      experimental-features = "nix-command flakes";
      # Opinionated: disable global registry
      flake-registry = "";
      # Workaround for https://github.com/NixOS/nix/issues/9574
      nix-path = config.nix.nixPath;
    };
    # Opinionated: disable channels
    channel.enable = false;
    # Opinionated: make flake registry and nix path match flake inputs
    registry = lib.mapAttrs (_: flake: {inherit flake;}) flakeInputs;
    nixPath = lib.mapAttrsToList (n: _: "${n}=flake:${n}") flakeInputs;
  };

I use 23.11 nixpkgs version and without adding the above code nix shell by default uses unstable branch.

What really? Then what is the use of the above mentioned code? Also I will do nix flake update and mention if it works or not afterwards.

@JManch Okay so I did nix flake update and I can still see the same thing.

Can you give me some hint. I have no idea how to do it.
what I am doing is I have set 23.11 in flake.nix and then trying to install some package lets say "appflowy"
in 23.11 the app version is 0.3.8 but in unstable it is 0.5.5.
I do nix shell nixpkgs#appflowy and it starts fetching nixpkgs-unstable branch and downloads the unstable version.

I can also see this if I abort the command using ctrl + c

error:
       … while fetching the input 'github:NixOS/nixpkgs/nixpkgs-unstable'

       error: download of 'https://github.com/NixOS/nixpkgs/archive/1c74cc292b61614e74c1cf0d372f79d57fb4936b.tar.gz' was interrupted

@JManch I added those and all the unstable words from flake.lock is gone. But still nix shell nixpkgs#packageName is using unstable branch. I should also mention that I removed this code, as you said it is already default to use the defined nixpkgs.
Flake.lock ->

@JManch Yeah that nix.registry.nixpkgs.flake = inputs.nixpkgs; did the job. But now I am super curious as to what is happening with my system, with question like, Should I add this line permanently of will a reinstall should fix it?, how did it even happen? why it worked before when I was adding registry and nixpath settings, etc etc

Thank god it wasn't a me issue. It's okay I have anyway added the misterio's nix registry and nixpath settings and that seem to work well, as now I can use both stable and unstable when doing nix shell, plus it solved the registry problem as well. And in the first I thought that it was only causing errors like what happened in this NIX_PATH issue, so I wanted to not use it but that turned out to be a nixos's underlining issue. Just hope that this issue gets solved so that I can remove nix-path = config.nix.nixPath; this workaround. At the end I have no one to blame to, just have thanks for @JManch for sticking around for what 2 days now. Thank you so much!

Now that NixOS/nix#11079 is merged should the workaround be removed?

Not yet, Nixpkgs still uses Nix 2.18.5 and the fix hasn't been backported
