My Dotfiles in Nix

NixOS

• Apply system configuration (nixos-install --flake .#hostname on live installation media)

sudo nixos-rebuild switch --flake .#sudarshan
# nh variant (path isn't required if programs.nh.flake is defined)
nh os switch . -c sudarshan

• Apply home configuration

nix shell nixpkgs#home-manager
home-manager switch --flake .#lokesh@sudarshan

• Update flake

nix flake update

Nix

• Install nix
  • DeterminateSystems
  • Official
  • Nix Portable (no root)

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

• Copy packages across systems over ssh (package management)

nix-copy-closure --to <username>@<ip> $(type -p <package-name>)

Neovim

• To run my configuration of neovim

nix run github:lokeshmohanty/nix#nvim

Dotfiles Setup

• Make git ignore machine specific configuration while keeping the default config in repository

git update-index --skip-worktree ./config/hypr/monitors.conf
git update-index --skip-worktree ./config/hypr/workspaces.conf

• You can get list of files that are marked to be skipped with

git ls-files -v . | grep ^S

Tips

• Use nix-prefetch-github to get the rev and hash information required for fetchFromGithub
