How can I import and built the script in ./miscellaneous/scripts.nix along with the main home.nix?
imports = [
./miscellaneous/scripts.nix
];
The above import does not work.
error: The option `environment' does not exist. Definition values:
- In `/nix/store/np3cpm4pz2d4h15gjnhjd9jaf0466d3c-source/miscellaneous/scripts.nix':
{
systemPackages = [
<derivation my-host-info>
...
I read that the environment does not exist. But, how do I export the script to the main home.nix?
Given, home.nix has the following content.
{ config, pkgs, ... }:
let
isLinux = pkgs.stdenv.hostPlatform.isLinux;
isDarwin = pkgs.stdenv.hostPlatform.isDarwin;
isAarch64 = pkgs.stdenv.hostPlatform.isAarch64;
isx86_64 = pkgs.stdenv.hostPlatform.isx86_64;
is64Bit = pkgs.stdenv.hostPlatform.is64Bit;
unsupported = builtins.abort "Unsupported platform";
in
{
imports = [
];
home.username =
if isLinux then
"CHANGEME"
else if isDarwin && isAarch64 then
"CHANGEME"
else if isDarwin && isx86_64 then
"CHANGEME"
else
unsupported;
home.homeDirectory =
if isLinux then
"/home/CHANGEME"
else if isDarwin && isAarch64 then
"/Users/CHANGEME"
else if isDarwin && isx86_64 then
"/Users/CHANGEME"
else
unsupported;
home.stateVersion = "24.05";
nixpkgs.config.allowUnfree = true;
home.packages =
with pkgs;
(
[
atuin
(nerdfonts.override {
fonts = [
"DejaVuSansMono"
];
})
(writeShellScriptBin "my-hello" ''
echo $(date --universal --iso-8601=seconds)
echo '----------------'
echo "Hello, ${config.home.username}!"
echo '----------------'
'')
]
++ lib.optionals isLinux [
util-linux
]
++ lib.optionals isDarwin [
pinentry_mac
]
++ lib.optionals (isDarwin && stdenv.isx86_64) [

++ lib.optionals (stdenv.isDarwin && stdenv.isAarch64) [

);
home.file = {
".gradle/gradle.properties".text = ''

org.gradle.daemon.idletimeout=3600000

};
home.sessionVariables = {

};
programs.home-manager.enable = true;
}
And, ./miscellaneous/scripts.nix has the following content.
{
pkgs,
lib,
config,
...
}:
