# NixOS Configuration
![NixOS configuration](/assets/example.png)

## Installation Guide

⚠️ **Important Notes**  
Before applying this configuration on another system, make sure to:
- Update the `hostName`.
- If your computer **is not a laptop**, set `isLaptop = false` in `~/nixos/other/quickshell/bar/Power.qml`.  
  *(This is hardcoded because `UPowerDevice.isLaptopBattery` didn’t work.)*

Requirements: `git` installed. Then run:

```bash
cd
git clone https://github.com/Totorile1/nixos.git
cd nixos
sudo cp /etc/nixos/hardware-configuration.nix ./hosts/laptop/hardware-configuration
sudo nixos-rebuild switch --flake ~/nixos/#laptop
```

### Things That Don't Work Reliably and need manual setup

### Framework 16 RGB Macropad

The **Framework 16 RGB macropad** is a 4×6 programmable key grid. Each key triggers one of the keybindings above via a macro.  

If you **don’t have the physical macropad**, the table below shows which keybinding each macro triggers so you can run it from the keyboard instead:

| Macropad Key | Linked Action (Hyprland keybinding)          |
| ------------ | -------------------------------------------- |
| Row 1, Col 1 | Kill all apps except focused (`Ctrl+$mod+6`) |
| Row 2, Col 1 | Performance mode (`Ctrl+Alt+7`)              |
| Row 3, Col 2 | Special characters (`Ctrl+$mod+3`)           |
| Row 3, Col 3 | Color picker (`Ctrl+Alt+8`)                  |
| Row 4, Col 1 | Notification center toggle (`Ctrl+Alt+1`)    |
| Row 4, Col 2 | System monitor (`Ctrl+Alt+2`)                |
| Row 4, Col 3 | Pomodoro timer (`Ctrl+Alt+0`)                |
| Row 4, Col 6 | Launch Anki (`Ctrl+Alt+9`)                   |

> Positions are labeled as `[row, column]` starting from top-left `[1,1]`.  
> Each macro calls a script or application from this configuration.

## Useful Information

- `man` and `manix` use `fzf` for fuzzy search of pages.  
- `pkgs-unstable` can be used for unstable nixpkgs packages.  
- Nix garbage collection runs weekly, deleting generations older than 7 days.  
- Non-free packages (e.g., Obsidian) are allowed.  
- `neovim` plugins configured in `./modules/home-manager/neovim.nix`  
- `oh-my-zsh` plugins configured in `./modules/home-manager/oh-my-zsh.nix`  
- `ripgrep` default flags: `-S -. -p -n`  
- Wallpapers change per workspace (5 paintings from Thomas Cole’s *The Course of Empire*).  
- LibreWolf search engines: `@q` (Quant), `@hm` (Home-manager), `@np` (nixpkgs), `@nw` (Nixwiki), `@map` (OpenStreetMap).  
- `ccat` colors `cat` output when not redirected; disables coloring if output is redirected (e.g., `>>`) to avoid breaking pipelines.  
- Anki addons: `./modules/nixos/anki.nix`  
- TLP config: `./modules/nixos/battery.nix`  
- Framework 16 RGB macropad layout: `./other/kblayouts/framework_laptop_16_rgb_macropad.layout.json`
