cd flake nix flake update git commit flake.lock sudo nixos-rebuild --flake . switch

Once changes have been made to this repo, commit them, then run sudo nixos-rebuild --flake . switch in this repo. This will switch the system to use the configuration in the flake at . (the current directory).

Run sudo nix-collect-garbage -d to remove old generations. ("Generations" is the NixOS term for versions of a system configuration.)

The easiest place to look is search.nixos.org. Searching, for example, "pavucontrol" there will show a list of results including the package pavucontrol.

Alternatively, if a CLI solution is desired, the command nix search nixpkgs pavucontrol can be used. (nixpkgs is the main repository of Nix packages.)

Most programs don't have any weird requirements (a "weird program" might need to run a system daemon, change what groups your user is in, or something else).

If you want to try out a "non-weird" program without installing it, you can run:

• nix run nixpkgs#pavucontrol to launch pavucontrol without installing it
• nix shell nixpkgs#pavucontrol to start a shell with pavucontrol installed

If you want to install a "non-weird" program, edit home.packages in home.nix. This would look like adding a line like pkgs.pavucontrol to the array.

"Weird" packages typically require a NixOS module or home-manager module. Search in home-manager's list of options and NixOS's options search for the program name. If there's an entry, it's probably weird. Text me if you see this, it's not hard but the syntax has to be right.

To upgrade the available packages without upgrading to the newest release, run nix flake update in this repo. This should change flake.lock if there was an update available, but will not apply the changes to the system. See the above "Applying Changes" section for instructions on applying changes.
