Custom Configurations

Zsh Aliases

The following aliases are defined in home-darwin.nix:

• oc: sudo opencode
• g: gemini
• k: kubectl
• rebuild: sudo darwin-rebuild switch --flake /Users/bence/nix
• gc: nix-collect-garbage -d

Brave Browser

• Default Browser: Brave is set as the default browser for http and https protocols using duti.
• Extensions: The configuration installs the "iCloud Passwords" extension.

Zed Editor

• Extensions: The configuration installs extensions for nix, python, and javascript.
• Settings: Various settings are configured, including the theme, keymap (VSCode), and terminal settings.

System Settings

The darwin.nix file includes several system customizations:

• Touch ID for sudo: Enabled.
• Startup Chime: Disabled.
• Dock: Customized with specific applications and settings.
• Finder: Path bar is shown, and items in the trash are removed automatically.
• Screensaver: Password is required.
• Control Center: Several items are hidden from the menu bar.
• Screencapture: Default target is the clipboard.
• Spotlight: Menu item is hidden.

Garbage Collection

The system is configured to automatically run Nix's garbage collector to delete packages older than 10 days. This helps to free up disk space. You can also manually run the garbage collector with the gc alias.

How to Apply the Configuration

To apply the configuration, run the following command from the root of this repository:

sudo darwin-rebuild switch --flake .

Alternatively, you can use the rebuild alias if you have sourced the zsh configuration.
