Nix Setup

This document provides instructions on how to set up and manage your Nix environment using Home Manager with a specific configuration.

How to Install

Nix

To install Nix in multi-user mode (recommended for most users), run the following command:

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

This script will download and install Nix with the necessary configurations.

Build and Activate Configuration

To build and activate the Home Manager configuration for the user, use the following commands based on your system:

For Linux

1. Build the configuration:

   nix build ~/.config/nixpkgs/#homeConfiguration.zeihanaulia.activationPackage -o ~/.config/nixpkgs/result

2. Activate the configuration:

   ~/.config/nixpkgs/result/activate switch --flake ~/.config/nixpkgs/#homeConfiguration.zeihanaulia

For macOS (Intel)

1. Build the configuration:

   nix build ~/.config/nixpkgs/#homeConfiguration.zeihanaulia.activationPackage -o ~/.config/nixpkgs/result

2. Activate the configuration:

   ~/.config/nixpkgs/result/activate switch --flake ~/.config/nixpkgs/#homeConfiguration.zeihanaulia

For macOS (M1)

1. Build the configuration:

   nix build ~/.config/nixpkgs/#homeConfiguration.zeihanaulia.activationPackage -o ~/.config/nixpkgs/result

2. Activate the configuration:

   ~/.config/nixpkgs/result/activate switch --flake ~/.config/nixpkgs/#homeConfiguration.zeihanaulia

Updating Flake Inputs

To update the lock file for specific inputs in your flake, use the flake lock command. For example, to update nixpkgs-unstable:

nix flake lock ~/.config/nixpkgs --update-input nixpkgs-unstable

This command updates the input for nixpkgs-unstable within your flake configuration.

Using Shell Aliases

For convenience, you can use the predefined shell aliases to manage your Nix configurations:

• Update a specific flake input:

  flakeup nixpkgs-unstable

• Build the activation package:

  nxb

• Activate the configuration:

  nxa

These aliases simplify the process of managing and updating your Nix environment.
