Install steps

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

Restart the shell after installation

2. Add nix-community cache

nix run nixpkgs#cachix -- use nix-community

3. Install homebrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# Disable analytics
/opt/homebrew/bin/brew analytics off

4. Clone config

git clone [email protected]:okkdev/dotnix.git

5. Symlink config

mkdir ~/.config
ln -s (pwd)/dotnix ~/.config/home-manager

6. Activate config

nix run home-manager -- switch

🚨 Fish needs to be added to /etc/shells manually:

chsh -s $HOME/.nix-profile/bin/fish

NixOS (fork)

1. Install NixOS using the standard installer

Troubleshooting

Too many open files (macOS)

sudo launchctl limit maxfiles 1024 unlimited
sudo launchctl stop org.nixos.nix-daemon
sudo launchctl start org.nixos.nix-daemon

Too many open files (NixOS)

ulimit -n 4096

Then retry your build command.
