- add home/theme.nix as the single Silicon Volt palette and pass it to home modules via extraSpecialArgs - drive foot, hyprland, hyprlock, mako, fzf, starship, rofi and the herdr picker from that palette; raw config files use @color@ tokens substituted at build time - pass my = config.my into home-manager; add my.pi.enable, my.flakeDir - gate home/pi.nix on my.pi.enable (enabled on hades) - route zshconf/hyprconf aliases and FLAKE_CONFIG through my.flakeDir - rename the hyprland monitor option volt.monitors -> hypr.monitors - fix use_auto_tmux command-substitution bug in zsh/init.zsh - track home/nvim/config/lazy-lock.json for reproducible plugins - document theming and toggles in the README

# NixOS Configs
|
|
|
|
Reproducible multi-host NixOS + Hyprland ("Silicon Volt") configuration.
|
|
|
|
## Install (new machine)
|
|
|
|
```bash
|
|
# Setup disks
|
|
nix run --experimental-features "nix-common flakes" github:nix-community/disko -- --mode disko --flake .#hades
|
|
|
|
# install configs
|
|
nixos-install --flake .#hades
|
|
|
|
# set password
|
|
nixos-enter --root /mnt -- passwd anish
|
|
```
|
|
|
|
## Rebuild (existing machine)
|
|
|
|
```bash
|
|
rebuild switch # zsh helper: sudo nixos-rebuild switch --flake ~/NixOS-Configs#<host>
|
|
```
|
|
|
|
## Adding a new host (e.g. a laptop)
|
|
|
|
1. Create `hosts/<name>/` with `default.nix`, `hardware-configuration.nix`, and
|
|
(optionally) `disko.nix`. Shared modules (`modules/core`, `modules/graphical`,
|
|
`modules/apps`) are already pulled in by `commonModules` in `flake.nix` — the
|
|
host only adds its own hardware/disko config.
|
|
2. Register it in `flake.nix` under `nixosConfigurations`.
|
|
3. Turn optional features on per machine via the shared `my.*` options:
|
|
|
|
```nix
|
|
# hosts/<name>/default.nix
|
|
my = {
|
|
username = "anish"; # default; change for a different primary user
|
|
gaming.enable = false; # Steam, Gamemode, MangoHud
|
|
ai.local.enable = false; # Ollama, ComfyUI, Open WebUI
|
|
pi.enable = false; # pi coding agent (home-manager)
|
|
};
|
|
```
|
|
|
|
4. Declare host-specific displays in `hosts/<name>/default.nix`:
|
|
|
|
```nix
|
|
home-manager.users.anish.hypr.monitors = [
|
|
{
|
|
output = "eDP-1"; # or "desc:<panel description>"
|
|
mode = "2880x1800@120Hz"; # or "preferred"
|
|
position = "auto";
|
|
scale = 2;
|
|
vrr = null; # optional per-monitor VRR
|
|
}
|
|
{ output = ""; mode = "preferred"; position = "auto"; scale = "auto"; } # fallback
|
|
];
|
|
```
|
|
|
|
The `hypr.monitors` default (any output @ preferred) keeps every machine working
|
|
out of the box; hosts override only what they need. Hosts without an NVIDIA GPU
|
|
simply don't import `modules/hardware/nvidia.nix` — all vendor env vars live there,
|
|
while the vendor-neutral `hardware.graphics` stack lives in `modules/graphical`.
|
|
|
|
## Feature toggles (`my.*`)
|
|
|
|
Optional app modules are always imported (via `modules/apps/default.nix`) but only
|
|
activate when a host sets the corresponding flag, so hosts never need to edit
|
|
import lists:
|
|
|
|
| Option | Enables |
|
|
| --- | --- |
|
|
| `my.username` | Primary user (users, home-manager, getty autologin) |
|
|
| `my.flakeDir` | Checkout path used by the `rebuild` helper and `zshconf`/`hyprconf` aliases |
|
|
| `my.gaming.enable` | Steam, Gamemode, MangoHud |
|
|
| `my.ai.local.enable` | Ollama (CUDA), ComfyUI, Open WebUI |
|
|
| `my.pi.enable` | pi coding agent (home-manager) |
|
|
|
|
Hardware modules remain explicit imports per host (e.g. `modules/hardware/nvidia.nix`).
|
|
|
|
## Theming
|
|
|
|
The Silicon Volt palette lives in one place, `home/theme.nix`, and is passed to
|
|
every home-manager module through `extraSpecialArgs`. Tools that only accept a
|
|
raw config file (starship, rofi, the herdr picker) carry `@color@` placeholders
|
|
that are substituted from the same palette at build time, so changing an accent
|
|
means editing one file.
