  echo "❌ Error: Project name required."
  echo "➡️  Try: rust-new --help"
  exit 1
fi

PROJECT_NAME="$1"

### --- Run cargo-generate ---
echo "🛠 Creating project '$PROJECT_NAME' from template..."
cargo generate --git "$TEMPLATE_REPO" --name "$PROJECT_NAME"

cd "$PROJECT_NAME"

if [[ -f "./post_gen.sh" ]]; then
  echo "🚀 Running post_gen.sh to create GitHub repo..."
  ./post_gen.sh
