dotfiles

My dotfiles managed by Nix, home-manager and nix-darwin.

Overview

I primarily use Macs, therefore this repo is (mainly) for darwin. However I do try to make it work on Linux as well.

Some features worth mentioning:

Declarative macOS with nix-darwin
zsh with p10k
tj/n instead of nvm
gpakosz/.tmux
fzf-tab for completion
Integration of fzf, fd, bat and lsd
- ^T: interactively select files in cwd recursively
  - ? to toggle preview
  - ^S ^D: page up/down
- ^O to open in $VISUAL (VS Code on macOS)
- Alt-C: interactive cd
Interactive git operations with forgit

Usage

On a new macOS machine w/o Nix installed:

xcode-select --install

# Install nix
bash <(curl -L https://nixos.org/nix/install) --daemon --yes --no-modify-profile

# Propagate /run
printf 'run\tprivate/var/run\n' | sudo tee -a /etc/synthetic.conf
/System/Library/Filesystems/apfs.fs/Contents/Resources/apfs.util -t

# Build the dotfiles
mkdir $HOME/.config
git clone https://github.com/birkhofflee/dotfiles $HOME/.config/nix
nix build "$HOME/.config/nix#darwinConfigurations.AlessandroMBP.system" --extra-experimental-features "nix-command flakes"

# Remove default nix config to mitigate https://github.com/LnL7/nix-darwin/issues/149
sudo rm -f /etc/nix/nix.conf
./result/sw/bin/darwin-rebuild switch --flake "$HOME/.config/nix#AlessandroMBP"

After first successful deployment, use the following command to switch:

darwin-rebuild switch --flake "$HOME/.config/nix#AlessandroMBP"

To update packages:

nix flake update .
nix flake update
