No matter what I try, I always get: <div class="snippet-clipboard-content notransl

<a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/us

Can you elaborate for beginners like me? My build (for netlify) looks like

@yajo You can produce the upgraded nix-portable declaratively by overriding the flake inputs.

from nix-portable.

Can you elaborate for beginners like me? My build script (for netlify) looks like

wget -nv https://github.com/DavHau/nix-portable/releases/download/v009/nix-portable
chmod +x nix-portable
./nix-portable nix-build

how would I change that to get a specific version of nix?

from nix-portable.

@nomeata Sorry for late reply.

As nix-portable enables the flake features by default, you can make use it to build and run the Nix Flakes. You can find a Flakes introduction on the NixOS Wiki:

https://nixos.wiki/wiki/Flakes

There are several ways to build nix-portable from flake.

The most reliable one is to write a flake.nix. This one will work if you simply want to get an updated nix-portable.

{
  description = "My custom overrided nix-portable flake";

  # The nixpkgs revision to use
  inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-21.11";
  # The nix revision to use
  inputs.nix.url = "github:NixOS/nix/2.5.1";
  inputs.nix.inputs.nixpkgs.follows = "nixpkgs";
  # We don't need to benchmark Nix here.
  # Let's opt out the additional nixpkgs
  # that causes constant changes of `flake.lock`.
  inputs.nix.inputs.nixpkgs-regression.follows = "nixpkgs";
  inputs.nix-portable-flake.url = "github:DavHau/nix-portable/v009";
  inputs.nix-portable-flake.inputs.nixpkgs.follows = "nixpkgs";
  inputs.nix-portable-flake.inputs.defaultChannel.follows = "nixpkgs";
  inputs.nix-portable-flake.inputs.nix.follows = "nix";

  outputs = { nix-portable-flake, ... }: nix-portable-flake.outputs;
}
