🚀 How to use ?

You probably want to use flakes to use the overlay and modules defined in this repo.

TODO: Show some basic examples on how to use the overlay/modules

Install on new system

1. Create partitions as per your requirements (e.g., using disko or parted).
2. Mount the partitions, excluding any tmpfs partitions.
3. Comment out the machine-id under impermanence.
4. Run the nixos-install command.
5. Copy the machine-id and other necessary files into the persisted directories.
6. Uncomment the machine-id.
7. Run the nixos-install command again.

nix-shell -p git
sudo nixos-install --flake uri#system

✨ Features

🤫 Impermanence

Instead of tediously specifying all the files you want to keep, the environment.state module allows you to specify only the folders you want to overlay by symlink or by mount. Say you have folders under /nix/state/users/name/data where you have all the folders which sadly do not follow the XDG directories like .ssh or .minecraft and you have your home folders like Desktop or Documents under /nix/state/users/name/home. Then you can specify the following config:

# system/config/<machine>/impermanence.nix
environment.state = {
    enable = true;
    targets = [
        {
            source = "/nix/state/users/name/home";
            destination = "/home/name";
            method = "mount";
            owner = "name";
            group = "users";
            mode = "0700";
        }
        {
            source = "/nix/state/users/name/data";
            destination = "/home/name";
            method = "mount";
            owner = "name";
            group = "users";
            mode = "0700";
        }
    ];
}

Now to include the right folders you can just put an @ behind every folder you want to overlay into the destination. For example your folder structure might look like the following:

/nix/state/users/name/home
    - Desktop@
    - Documents@
        - important_stuff
        - inner_folder
    - some_other_folder

Now Desktop@ and Documents@ will be mounted/symlinked at startup to your home folders Desktop and Documents

🦊 Firefox Addons

Under pkgs/by-scope/firefox-addons are a bunch of firefox addons defined. But instead of manually creating derivations for each addon, the addons are generated via the pkgs/by-scope/firefox-addons/mod.nu nushell script. The resulting default.lock is then used to create the respective derivations.

Now to add addons you can just add the slugs into the pkgs/by-scope/firefox-addons/mod.nu script and recreate the default.lock file by running just update

Disclaimer: Due to some limitations of nushell, at the moment the path of default.lock is hardcoded into pkgs/by-scope/firefox-addons/mod.nu. You might probably want to change that

💻 Vscode Extensions

The vscode extensions are very similar to the firefox addons and are defined under pkgs/by-scope/vscode-extensions. The disclaimer also applies!

🚧 WIP Intel OneAPI

In an effort to make the Intel Extension for Pytorch work, I created a multitude of packages. Under pkgs/by-scope and pkgs/by-name are lying the intel oneapi packages like dpcpp or mkl.

To use the dpcpp compiler you may want to use dpcppStdenv, which is currently somewhat functional.

🛑 Other packages

There exist some packages in this repository which are not functional at the moment. I still keep them in here as documentation for future packaging efforts. I try to mark them as broken but I might have forgotten some. If you encounter any broken packages please create an issue.
