# Configuration Example {#sec-usage-configuration}
|
|
|
|
|
|
|
|
|
|
A fresh install of Home Manager will generate a minimal
|
|
|
|
|
`~/.config/home-manager/home.nix` file containing something like
|
|
|
|
|
|
|
|
|
|
``` nix
|
|
|
|
|
{ config, pkgs, ... }:
|
|
|
|
|
|
|
|
|
|
{
|
|
|
|
|
# Home Manager needs a bit of information about you and the
|
|
|
|
|
# paths it should manage.
|
|
|
|
|
home.username = "jdoe";
|
|
|
|
|
home.homeDirectory = "/home/jdoe";
|
|
|
|
|
|
|
|
|
|
# This value determines the Home Manager release that your
|
|
|
|
|
# configuration is compatible with. This helps avoid breakage
|
|
|
|
|
# when a new Home Manager release introduces backwards
|
|
|
|
|
# incompatible changes.
|
|
|
|
|
#
|
|
|
|
|
# You can update Home Manager without changing this value. See
|
|
|
|
|
# the Home Manager release notes for a list of state version
|
|
|
|
|
# changes in each release.
|

|
|
|
home.stateVersion = "24.05";
|
2024-01-05 11:06:15 +00:00
|
|
|
|
|
|
|
|
# Let Home Manager install and manage itself.
|
|
|
|
|
programs.home-manager.enable = true;
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
You can use this as a base for your further configurations.
|
|
|
|
|
|
|
|
|
|
::: {.note}
|
|
|
|
|
If you are not very familiar with the Nix language and NixOS modules
|
|
|
|
|
then it is encouraged to start with small and simple changes. As you
|
|
|
|
|
learn you can gradually grow the configuration with confidence.
|
|
|
|
|
:::
|
|
|
|
|
|
|
|
|
|
As an example, let us expand the initial configuration file to also
|
|
|
|
|
install the htop and fortune packages, install Emacs with a few extra
|
|
|
|
|
packages available, and enable the user gpg-agent service.
|
|
|
|
|
|
|
|
|
|
To satisfy the above setup we should elaborate the `home.nix` file as
|
|
|
|
|
follows:
|
|
|
|
|
|
|
|
|
|
``` nix
|
|
|
|
|
{ config, pkgs, ... }:
|
|
|
|
|
|
|
|
|
|
{
|
|
|
|
|
# Home Manager needs a bit of information about you and the
|
|
|
|
|
# paths it should manage.
|
|
|
|
|
home.username = "jdoe";
|
|
|
|
|
home.homeDirectory = "/home/jdoe";
|
|
|
|
|
|
|
|
|
|
# Packages that should be installed to the user profile.
|
|
|
|
|
home.packages = [
|
|
|
|
|
pkgs.htop
|
|
|
|
|
pkgs.fortune
|
|
|
|
|
];
|
|
|
|
|
|
|
|
|
|
# This value determines the Home Manager release that your
|
|
|
|
|
# configuration is compatible with. This helps avoid breakage
|
|
|
|
|
# when a new Home Manager release introduces backwards
|
|
|
|
|
# incompatible changes.
|
|
|
|
|
#
|
|
|
|
|
# You can update Home Manager without changing this value. See
|
|
|
|
|

|
|
|
|
# changes in each release.

|
|
|
home.stateVersion = "24.05";
|
2024-01-05 11:06:15 +00:00
|
|
|
|
|
|
|
|
# Let Home Manager install and manage itself.
|
|
|
|
|
programs.home-manager.enable = true;
|
|
|
|
|
|
|
|
|
|
programs.emacs = {
|
|
|
|
|
enable = true;
|
|
|
|
|
extraPackages = epkgs: [
|
|
|
|
|
epkgs.nix-mode
|
|
|
|
|
epkgs.magit
|
|
|
|
|
];
|
|
|
|
|
};
|
|
|
|
|
|
|
|
|
|
services.gpg-agent = {
|
|
|
|
|
enable = true;
|
|
|
|
|
defaultCacheTtl = 1800;
|
|
|
|
|
enableSshSupport = true;
|
|
|
|
|
};
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- Nixpkgs packages can be installed to the user profile using
|
|
|
|
|
[home.packages](#opt-home.packages).
|
|
|
|
|
|
|
|
|
|
- The option names of a program module typically start with
|
|
|
|
|
`programs.<package name>`.
|
|
|
|
|
|
|
|
|
|
- Similarly, for a service module, the names start with
|
|
|
|
|
`services.<package name>`. Note in some cases a package has both
|
|
|
|
|
programs *and* service options -- Emacs is such an example.
|
|
|
|
|
|
|
|
|
|
To activate this configuration you can run
|
|
|
|
|
|
|
|
|
|
``` shell
|
|
|
|
|
home-manager switch
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
or if you are not feeling so lucky,
|
|
|
|
|
|
|
|
|
|
``` shell
|
|
|
|
|
home-manager build
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
which will create a `result` link to a directory containing an
|
|
|
|
|
activation script and the generated home directory files.
