pay attention to:

• nix-jargon
• how vid-vimjoyer-nix_language, vid-vimjoyer-nix_function were used
• flake structure

note

• nix flake show = useful to see flake inputs
• flake inputs = other flakes from the outside
• flake outputs = function of our flake
• fn (fn_inputs ) = fn_outputs
  • flake inputs <=dump= fn_inputs
• default in fn_outputs : when use flake without #, this default will run
• good practice to define var in flake output (let … in …)
• another good standard
  • outputs = inputs@{nixpkgs, ...}:
  • evolved from
    • outputs = inputs:
      • still need to input.something
    • output = {nixpkgs, self}:
• we can set flake A (e.g. home-manager) to follow flake B (e.g. nixpkgs)
• flake and nixosConfiguration
  • modules
  • specialArgs
    • passing extra arguments to modules
    • general usecase :inherit inputs
      • means inputs = inputs
      • so we can specify inputs in every modules
