# A Nix Module can be an attribute set, or a function that

# returns an attribute set. By default, if a Nix Module is a
|
|
# function, this function can only have the following parameters:
|
|
#
|
|
# lib: the nixpkgs function library, which provides many
|
|
# useful functions for operating Nix expressions:
|
|
# https://nixos.org/manual/nixpkgs/stable/#id-1.4
|
|
# config: all config options of the current flake, every useful
|
|
# options: all options defined in all NixOS Modules
|
|
# in the current flake
|
|
# pkgs: a collection of all packages defined in nixpkgs,
|
|
# plus a set of functions related to packaging.
|
|
# you can assume its default value is
|
|
# `nixpkgs.legacyPackages."${system}"` for now.
|
|
# can be customed by `nixpkgs.pkgs` option
|
|
# modulesPath: the default path of nixpkgs's modules folder,
|
|
# used to import some extra modules from nixpkgs.
|
|
# this parameter is rarely used,
|
|
# you can ignore it for now.
|
|
#
|
|
# Only these parameters can be passed by default.
|
|
# If you need to pass other parameters,
|
|
# you must use `specialArgs` by uncomment the following line:
|
|
#
|
|
# specialArgs = {...} # pass custom arguments into all sub module.
