This is my setup for NixOS.
- reproducible
- NixOS with flakes to lock versions
- ephemeral root to stay conscious about unreproduced state
- ergonomics
- keyboard-first favoring vim-like keybinds
- intuitiveness
- scrollable tiling

JIT-installed neofetch
thefuck plugin for zsh (hit double Esc) filled the JIT-install command for the missing app neofetch.
the expanded notification bar SwayNotificationCenter is shown with a notification about a completed rebuild. this menu can be opened using `Super+`` or by right-clicking the 'Windows' button.
file managers
yazi is a terminal-based file manager with vim-like keybindings.
thunar is available as a graphical alternative.
terminal-based IDE
running ide in the WezTerm terminal opens a terminal-based IDE at that directory, consisting of:
- Git TUI
lazygit, offering a terminal-based way to work with Git repositories, including vim keybindings. helix, featuring language servers for nix (thrunixd) and others- a shell, using Zsh and decorated using
powerline-go
As a back-up, the graphical VSCodium is provided (with some plugins).
application menu
Application menu anyrun can be opened using Super+Space or by left-clicking the 'Windows' button.
JIT application menu
A menu to JIT-install and run applications can be opened using Super+Shift+Space.
show dependency age
command just age showing the age of any dependencies included in flake.lock
emoji picker
pressing the Microsoft keyboard's emoji key](https://support.microsoft.com/en-us/topic/use-microsoft-ergonomic-keyboard-c917dad0-3797-d97b-efb3-fbe27ac9703c#ID0EDFBBDDD) (Super-Ctrl-Alt-Shift-Space) triggers an emoji picker using fuzzy picker fzf.
file picker
pressing CTRL-T in the shell opens fzf's file picker, copying the selected file or directory path to the clipboard.
This configuration was made with the following devices in mind:

- update
./hosts/<PROFILE>/hardware-configuration.nix - on an existing system, disable impermanence to prevent existing files not opted into persistence from being wiped on boot
- replace currently hardcoded values
- get a user password by either:
- setting one in
./hosts/<PROFILE>/configuration.nix - decoding secrets by adding the
agekeys file to/etc/nixos/keys.txt
- setting one in
clean install from NixOS USB

Available recipes:
age # Check when inputs were last updated
boot # Build a new configuration
clean # Remove all generations older than 7 days
decode # Decode secrets
default # default action: list actions
dry # Dry-build a new configuration
encode # Encode secrets
ephemeral dir="$HOME" # Show what has yet to be persisted in a folder. Usage: just ephemeral $PWD | $PAGER
fmt # Format code
gc # Garbage collect all unused nix store entries
home # Rebuild the home config
repl # Open a Nix REPL - run manually to load flake: `:lf .`
switch # Rebuild the system
test # Run tests
up # Update all inputs
upp input # Update specific input. Usage: just upp nixpkgs... or if just isn't available yet:
nix run nixpkgs#just -- -lto ensure you can persist useful state on an ephemeral system, you can find say:
- newly created (5 mins) files:
find ~ -cmin -5 - files now on root:
tree -x / - diffs from last backup:
rsync --dry-run
- secrets: sops
- formatter: treefmt
- commands: just
- CI: garnix
- cache:
./cachix/ - environment loader: direnv
- declarative partitioning: disko
- ephemeral root: impermanence
- the
flake.locked nixpkgs is used for:- nix commands
- 'command not found' errors

Used keyboard layouts, with Caps Lock remapped to Esc:
- workman-programmer, with application keymaps modified to keep arrow actions
h/j/k/l(+ actions 'y'/'n') in their ergonomic qwerty positions (at the cost of moving actionse/oto keysh/l) en-us(qwerty)
Application keybinds, tweaked to layout by setting config.keyboard.active:
