# =========================================================
# Cursor Remote Server Update Script
# Used to download Cursor server files locally and then upload them to a remote Linux server
# =========================================================

# ==================== Local Configuration ====================
SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" &> /dev/null && pwd )"
LOCAL_DOWNLOAD_DIR="$SCRIPT_DIR/cursor_downloads" # Local download directory

# Remote server configuration
REMOTE_PORT=22 # SSH port
REMOTE_USER="root" # Remote username
REMOTE_HOST="mycloud.com" # Remote host

# ==================== Target Architecture Configuration ====================
# Local architecture - determines which version you want to download locally
# Possible values: "x64" or "arm64"
# - x64: For Intel-based Macs
# - arm64: For Apple Silicon (M1/M2/M3) based Macs
LOCAL_ARCH="arm64"

# Remote architecture - determines which version you want to use on the remote server
# Possible values: "x64" or "arm64"
# - x64: For Intel/AMD servers (most common)
# - arm64: For ARM-based servers (e.g., AWS Graviton)
REMOTE_ARCH="x64"

# Remote operating system - usually Linux
# Possible values: "linux"
# Note: Cursor server currently mainly supports Linux
REMOTE_OS="linux"
