My Nix home

This repos contains the NixOS and home-manager configuration for all my computers. It is organised in the following way:

• flake.nix: Tie everything together. It is responsible for propagating the modules and overlays from the inputs to the rest of the config. As of now it is a big spaghetti code that shouldn't be edited often.
• utils.nix: Helper library functions that are needed to manipulate modules, ie cannot depend on value set through the module system.
• lib: A directory of helper functions that are made available to modules through config.lib.
• packages: Individual packages definition, instantiation through an overlay in packages/default.nix. Packages defined here will be exposed as package output of the flake.
• overlays: Additional overlays I may need. Overlays defined here will be exposed as overlay output of the flake.
• modules: Additional modules for every module system. The subdirectories define at which step of the module hierarchy they should be applied. As of now three types of modules are supported nixos ones, hm ones and nixvim ones. Modules defined here will be exposed as nixosModules, hmModules and nixvimModules respectively in the outputs of the flake.
• profiles: Profiles are modules that don't define options. Most of the concrete configuration is done through this. Like modules, they are split depending on their kind, being nixos, hm or nixvim as of now. Each profile should be defined as a default.nix in a directory. Those files will be automatically found, and exposed as options that can be enabled. For example, a file hm/interface/theme/default.nix will be exposed as an option in home-manager named interface.theme.enable that when toggled will have the same effect as importing the previous file.
• hosts: Top level configurations for computers. All home-manager configurations must be used from those, they are not exposed otherwise. Semantically this is the entry points of the configurations. They are exposed in the nixosConfigurations output of the flake.

Miscellaneous

Some effort has been done to create a uniform feeling and theme across applications. To do so I am actually using nix-colors, but I am planning to move to stylix when after refactoring it.

After using Doom Emacs for some years, I am in the process of moving to neovim, configured through nixvim. As of now the setup is a ugly mix of part of configuration for the two of them.

Instead of setting up the packages and editor for different languages directly in the home-manager configuration, I'd like to expose it as devshells that I can use in different projects. Maybe do something based on devenv.sh.

As of now there is no way to handle secrets in the configuration, and this is a problem.

This whole repository is definitely overengineered, but it is fun to hack on.
