A set of named specialized configurations. These can be used to extend
|
|
your base configuration with additional settings. For example, you can
|
|
have specialisations named "light" and "dark"
|
|
that apply light and dark color theme configurations.
|
|
|
|
::: {.note}
|
|
This is an experimental option for now and you therefore have to
|
|
activate the specialisation by looking up and running the activation
|
|
script yourself. Running the activation script will create a new
|
|
Home Manager generation.
|
|
:::
|
|
|
|
For example, to activate the "dark" specialisation, you can
|
|
first look up your current Home Manager generation by running
|
|
|
|
```console
|
|
$ home-manager generations | head -1
|
|
2022-05-02 22:49 : id 1758 -> /nix/store/jy…ac-home-manager-generation
|
|
```
|
|
|
|
then run
|
|
|
|
```console
|
|
$ /nix/store/jy…ac-home-manager-generation/specialisation/dark/activate
|
|
Starting Home Manager activation
|
|
…
|
|
```
|
|
|
|
::: {.warning}
|
|
Since this option is experimental, the activation process may
|
|
change in backwards incompatible ways.
