ヒアドキュメントと空白のみの行があるファイルのレイアウト調整に失敗する #59

Closed nabetani closed 3 years ago

nabetani commented 5 years ago

詳細な再現条件は不明ですが、

は必須のようです。 再現動画を https://github.com/nabetani/cop-throws-away/blob/master/movie.mp4 に置きました。 動画のとおり、インデントを増やす→その結果をファイルに書き込む→またインデントを増やす…… を繰り返すようです。 同リポジトリにある https://github.com/nabetani/cop-throws-away/blob/master/sample.rb が現象が再現するファイルです。

動画はソースコードが画面から消え去った時点で終わっていますが、最終的には以下のようなエラーが出て終了します:

Infinite loop detected in /略/cop-throws-away/sample.rb.

フィードバックありがとうございます。再現しました。Layout/TrailingWhitespace cop や Layout/IndentHeredoc cop あたりに何かしらの問題があるかもしれません。
