# x-adapter インストーラ。
#
# 何をするか:
#   X.com の x-web バンドル移行で twitter-cli の transaction-id 生成が壊れたため、
#   twscrape (新バンドル対応の XClIdGen) + twikit を使う twitter-cli 互換アダプタを
#   隔離 venv に入れ、`x-adapter` という実行ファイルを ~/.local/bin に置く。
#
# 使い方:
#   ./scripts/install-x-adapter.sh            # 新規インストール
#   ./scripts/install-x-adapter.sh --upgrade  # twscrape/twikit を最新へ (X が再破壊した時の修復レバー)
#
# 終わったら config.yaml に:
#   tools:
#     x_cli_command: [x-adapter]
