I made a simple update script for those not using AUR package

[taksyon]

The script uses git pull so local tweaks are not preserved.

#!/bin/bash

# safety
set -Eeuo pipefail

# formatting
r=$'\033[0m'     # reset

b=$'\033[34m'    # blue
y=$'\033[33m'    # yellow

# directory vars
BCKUP_DIR="$HOME/backup"
QCKSH_DIR="${XDG_CONFIG_HOME:-$HOME/.config}/quickshell"
CAE_DIR="$QCKSH_DIR/caelestia"

# flag for backup
BKUP=true

# sanity: make sure commands/directory exist
for cmd in git cmake ninja; do
  command -v "$cmd" >/dev/null || { printf "Missing required tool: %s\n" "$cmd"; exit 1; }
done
if [[ ! -d "$CAE_DIR" ]]; then
  printf "This script requires %shttps://github.com/caelestia-dots/shell%s to be installed. Exiting...\n" "$ul" "$r"
  exit 1
