# === How-To ===
# - Ensure brew, fzf, and vault are installed
# - Set VAULT_NAMESPACES env var as a comma-separated list of your Vault namespaces
# - Run this script and fuzzy select a Vault namespace from $VAULT_NAMESPACEs to export to $VAULT_NAMESPACE

set -euo pipefail

# === Check that required binaries are installed via brew ===
require_brew_bin() {
  local bin="$1"
  if ! command -v "$bin" >/dev/null 2>&1; then
    echo "❌ $bin not found. Install via: brew install $bin"
    exit 1
  fi
}

require_brew_bin fzf
require_brew_bin vault

# === Ensure VAULT_NAMESPACES env var is set and not empty ===
if [[ -z "${VAULT_NAMESPACES:-}" ]]; then
  echo "❌ VAULT_NAMESPACES env var not set."
  exit 1
fi

# === Split VAULT_NAMESPACES into an array by comma ===
IFS=',' read -r -a namespaces <<<"$VAULT_NAMESPACES"

if [[ "${#namespaces[@]}" -eq 0 ]]; then
  echo "❌ No namespaces found in VAULT_NAMESPACES."
  exit 1
fi

# === Use fzf for interactive selection ===
selected=$(printf '%s\n' "${namespaces[@]}" | fzf --prompt="Select Vault Namespace: ")

if [[ -z "$selected" ]]; then
  echo "❌ No namespace selected."
  exit 1
fi

export VAULT_NAMESPACE="$selected"
echo "✅ VAULT_NAMESPACE set to '$VAULT_NAMESPACE'"

# === Suggest how to persist the change ===
echo "ℹ️  To persist, add this to your shell: export VAULT_NAMESPACE='$VAULT_NAMESPACE'"
