This is my ~ configuration. It uses Nix and home-manager because of course it does.
On a new machine:
git clone git@github.com:jrockway/dotfiles ~/.dotfiles
sh <(curl -L https://nixos.org/nix/install) --daemon
# or sh <(curl -L https://nixos.org/nix/install) # on mac os
ln -s $HOME/.dotfiles/config/nix ~/.config/nix
ln -s $HOME/.dotfiles/config/home-manager ~/.config/home-manager
nix run home-manager/release-25.11 -- switch
ln -s $HOME/.dotfiles/ssh/authorized_keys ~/.ssh/authorized_keys
For help configuring home-manager:
man home-configuration.nix
If you want to steal something from here, feel free, but I mostly use flat
config files and not the fancy home-manager program.<whatever> = { ... };
method. You should probably do that instead if you're less lazy than me.
