# lib/mkHome.nix — Compose a complete home-manager configuration.
|
|
#
|
|
# This is the central function that replaces the old mkHomeConfig from nixos-config.
|
|
# It assembles imports based on three dimensions:
|
|
#
|
|
# WHO you are → user + identity (preferences + git/ssh/jj config)
|
|
# WHAT you do → context (desktop|server) + sets (coding, gaming, media)
|
|
# WHERE you are → host (handled by nixos-config, only overrides here)
|
|
#
|
|
# Usage:
|
|
# imports = [ (m3ta-lib.mkHome {
|
|
# user = "m3tam3re";
|
|
# identity = "private"; # or "work"
|
|
# context = "desktop"; # or "server"
|
|
# sets = [ "coding" "gaming" "media" ];
|
|
# }) ];
|
|
#
|
|
# Then override host-specific settings in the consuming module:
|
|
# m3ta.home.sets.coding.languages.python.extra = true;
|
|
# wayland.windowManager.hyprland.settings.monitor = [ ... ];
|
|
#
|
