#!/usr/bin/env bash
# sway-rising installer (Fedora): the "glass" look on SwayFX + DankMaterialShell, with kitty,
# fonts, wallpaper, hotkeys and screenshots. Your existing configs are backed up first.
#
# Usage: ./install.sh [options]
#   -y, --yes          do not ask questions (non-interactive)
#       --dry-run      print what would be done, change nothing
#       --check        only run the health check and exit
#       --restore [DIR]  put your old configs back from a backup (default: the OLDEST ~/rice-backup-*, i.e. before the rice)
#       --layouts L    keyboard layouts, e.g. "us,de" (default: ask; "us,ru" with --yes)
#       --no-packages  configs only, skip package installation
#       --no-dms       do not install DankMaterialShell
#       --with-shell   also install zsh, oh-my-zsh, tmux and CLI tools (fzf, zoxide, eza, ...) with their configs
#       --force-shell  with --with-shell: replace an existing ~/.zshrc (the old one is backed up)
#   -h, --help
