Rubyは常に2つのスペースをインデントしますか？

私はいつものように2スペースのインデントを使いたいです：

sidekiq_options({
  retry: true
})

私は次のように設定しようとし.emacs.d/init.elました：

(setq-default indent-tabs-mode nil)
(setq-default tab-width 2)
(setq indent-line-function 'insert-tab)

(setq ruby-deep-indent-paren nil)
(setq ruby-deep-indent-paren-style nil)

しかし、私はまだ次のように見えます：

sidekiq_options({
                  retry: true
                })

私はrubyユーザーではありませんが、以下を試すことができます。

(setq-default indent-tabs-mode nil)
(setq-default tab-width 4)   ;; change this to 2 if that is the width
(setq indent-line-function 'insert-tab)

あなたがしなければならないすべては設定することruby-indent-levelです。例えば(setq-local ruby-indent-level 2)。

編集：

enh-ruby-mode、melpaからインストール可能、およびを使用できます(setq enh-ruby-deep-indent-paren nil)。

これにより、次のインデントが発生しました。

sidekiq_options({
  retry: true
})

のコードを見ると、ruby-mode設定する方法がないようです。回避策は、関数をオーバーライドすることです。以下のコードを試して、機能するかどうかを確認してください。

(defun ruby-smie-rules (kind token)
  (pcase (cons kind token)
    (`(:elem . basic) ruby-indent-level)

    ;; should be aligned with the first.

私が編集した部分はのすぐ下にありFIXME、に変更(smie-rule-parent)しました。
