Dotfiles

Configs for three systems — macOS, Windows 11 and NixOS — plus a shared zsh setup. Every system runs a tiling WM, and the keybinding letters are kept the same across all of them wherever the platform allows it.

mac/aerospace/aerospace.toml     AeroSpace — tiling WM
mac/ghostty/config               Ghostty — terminal
mac/herdr/config.toml            herdr — alt as the modifier
windows/                         submodule → win-ricing, the whole Windows rice
nixos/                           flake, NixOS + home-manager, Hyprland
zsh/.zshrc                       portable zshrc for macOS / WSL / Debian
shell/env.sh                     env, PATH and aliases, sourced by .zshrc
wsl/ssh-agent.service            systemd user unit keeping the SSH key unlocked

The whole Windows side — configs and the rest of the rice — lives in win-ricing and is pulled in here as the windows submodule:

git clone --recurse-submodules git@github.com:kremeshnoi/dotfiles.git
git submodule update --init   # if already cloned

Shared mnemonics

Workspace	macOS	Windows
term	cmd+shift+t	lwin+t
chrome	cmd+shift+g	lwin+g
claude	cmd+shift+c	lwin+c
obsidian	cmd+shift+o	lwin+o
slack / spotify	cmd+shift+s	lwin+s
misc	cmd+shift+9	lwin+9
desktop	cmd+shift+0	lwin+0

The letter follows the app name; digits sit at the edges of the number row. Modifiers differ because each platform leaves a different one free: cmd+shift on macOS, lwin on Windows (see win-ricing for why), SUPER on Hyprland.

Both WM configs route windows by app id / process name and send everything unmatched to misc through a catch-all rule.

macOS

AeroSpace + Ghostty:

brew install --cask nikitabobko/tap/aerospace ghostty
ln -sf "$PWD/mac/aerospace/aerospace.toml" ~/.config/aerospace/aerospace.toml
ln -sf "$PWD/mac/ghostty/config" ~/.config/ghostty/config

AeroSpace starts at login (start-at-login = true) and triggers a sketchybar event on workspace change — drop exec-on-workspace-change if sketchybar isn't installed. cmd+shift+; enters service mode: esc reloads the config, r flattens the layout, f toggles floating/tiling, hjkl join with a neighbour, backspace closes every window but the current one.

Ghostty runs macos-option-as-alt = true, which is what frees Alt for nvim and herdr. Splits are on cmd+ctrl+hjkl, creating them adds shift.

Windows

See win-ricing, mounted here as windows/ — GlazeWM, the AutoHotkey script that kills the Start menu on a lone Win press, four Windhawk mods, herdr navigation over the socket API, Raycast, Spicetify, and removing Xbox Game Bar to free Win+G.

NixOS

Flake with home-manager, host alex-nixos, user alex. Hyprland + caelestia as the shell, greetd for login, PipeWire for audio, NVIDIA drivers.

sudo nixos-rebuild switch --flake .#alex-nixos

nixos/configuration.nix is system-level, nixos/home.nix is home-manager (Hyprland settings included), nixos/home/shell.nix is the zsh config, nixos/home/packages.nix is the user package list. hardware-configuration.nix is machine-specific and won't transfer to another box.

Hyprland uses SUPER for workspaces 1..4 and SUPER+hjkl for focus; ALT handles the launcher, terminal and window close, so the Alt-based navigation matches the other systems.

zsh

zsh/.zshrc is the portable version, used on macOS, WSL and Debian. NixOS doesn't use it — there zsh is generated from nixos/home/shell.nix, with the same history, plugin and highlighting settings.

ln -sf "$PWD/zsh/.zshrc" ~/.zshrc

Plugins (autosuggestions, fzf, syntax-highlighting) are sourced through a _try_source helper that walks a list of candidate paths — Homebrew, Debian, /usr/local, nix-profile — and takes the first one that exists, so the same file works everywhere without conditionals per OS. Anything machine-specific goes into ~/.zshrc.local, which is sourced last and never committed.

The prompt is bash-style with a git branch via vcs_info. Accent colour #FFBAF3 is shared with the syntax highlighting.

.zshrc sources shell/env.sh on its first line, so that file has to be in place or PATH entries, aliases, fzf variables and SSH_AUTH_SOCK all silently go missing:

cp shell/env.sh ~/.config/shell/env.sh

SSH_AUTH_SOCK there points at an agent started by systemd, which is what stops git from asking for the key passphrase on every push. WSL runs systemd with a user session, so the unit works as-is:

cp wsl/ssh-agent.service ~/.config/systemd/user/ssh-agent.service
systemctl --user enable --now ssh-agent.service
loginctl enable-linger "$USER"
ssh-add ~/.ssh/id_ed25519

~/.ssh/config carries AddKeysToAgent yes, so the passphrase is asked once per WSL start and then never again. enable-linger keeps the agent alive after the last terminal closes.

herdr

The same hjkl navigation on both systems — h/l switch tabs, j/k switch agents, adding shift switches workspaces — but reached in two different ways, because only macOS can express it in herdr's own config.

macOS uses alt: Ghostty passes Option through as Alt, so herdr sees the combo itself.

cp mac/herdr/config.toml ~/.config/herdr/config.toml

Windows runs the same jumps on lwin without touching [keys] at all. Win combos never reach a TUI sitting behind the terminal, so AutoHotkey catches the key on the Windows side and calls herdr-nav, which drives herdr over its socket API. Those six entries are blanked out in the Windows copy of config.toml to keep a single path per action; prefix = "ctrl+z" stays for pane navigation, which has no lwin equivalent. Both files live in win-ricing under herdr/, together with the setup notes and the registry policy that frees Win+L.
