Nix flakes explained

Enabling flakes:
nixos.wiki/wiki/Flakes - commands are here
Creating a flake:
$ nix flake init
Updating a flake:
$ nix flake update
Flake:
```
{
description = "my epic vims collection";
inputs = {
nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
};
outputs = { self, nixpkgs }:
let
system = "x86_64-linux";
pkgs = nixpkgs.legacyPackages.${system};
in
{
bob =
pkgs.mkShell
{
buildInputs = [
pkgs.neovim
pkgs.vim
];
shellHook = ''
echo "hello mom"
'';
};
};
}
```
(yes, I know I could push it to github, but I'm extra lazy today)

    If my arithmetic is correct, you said nix twenty-seven (27) times. You said flake twenty-four (24) times, although technically thirteen (13) of the twenty-four (24) times was in the plural form as flakes. Nix, flakes, and cookies... yummy. :-) Keep up the excellent work with Nix and NixOS, as some of us are learning along with your videos and they help a lot. Thank you.

    Also, if you have run out of cookies to send me, no problem. As a cookie substitution, I would really appreciate trying to understand how I could get dGPU passthrough to a VM figured out on a laptop, which has an AMD iGPU, and an AMD dGPU. I would like to be able to use NixOS for the base operating system, which would use the AMD iGPU, and then passthrough the AMD dGPU to a Windows VM so that the kids can use the laptop for school, Roblox programming, and gaming. Let me know if you think that this would make a great video, and if not, no worries. Thank you.

    ​@@Becoming-HumanI've actually managed to setup GPU pass through on NixOS on my Lenovo legion 5 amd + nvidia dgpu about 3 months ago. It was kind of easy on NixOS, because I didn't worry about blacklisting something important. Maybe I'll do a video about it later.

    This comment for the YT engagement algorithm: my Emacs bros would be mad at me watching content from someone called Vimjoyer, but I don't care. After having just gone though a painful Debian reinstall, I wondered if there was a better way. Nix might be it. Or it might be Guix (who knows?). For the time being, I am grateful for these videos.

    Thanks for a great intro to flakes! I'm not following what you mean with "if you named your dev shell bob ... you will have to use bob as key when running nix develop". What is a dev shell and how do you name it?

  • @brainstormsurge154
    @brainstormsurge154Ай бұрын

    Really loved the bob example just to show how to do it with any variable. Although I'm curious if you could do "bob.default" so you don't have to use the "#" in the command or would it need to be the whole "devshells.bob.default". What if it was just "devShells.bob"? Just curious since I'm just learning this.

    These development environments are not actually containers, they just modify some environment variables such as $PATH and $LD_LIBRARY_PATH to achieve what you see. They don't have their own storage, and you can access all your data. Flakes are just a way to declare those environments. That being said, you can build your docker images with nix: nixos.wiki/wiki/Docker You could use flakes to declare those as well.
