emacs - 在 Emacs 中重新定义 ENTER 键

Question

我不知道 elisp，但我正在尝试执行以下操作:

(add-hook
 'scala-mode-hook
 (lambda ()
   (define-key scala-mode-map (kbd "RET") (lambda ()
                                            (scala-newline)
                                            (scala-indent-line)))))

目标是每次按下 ENTER 键时调用这两个函数。我实际上如何做到这一点？

Answer 1

我基本上以多种模式执行此操作，以至于我将它们全部压缩在一起:

(mapcar (lambda (hooksym)
          (add-hook hooksym
                    (lambda ()
                      (local-set-key  (kbd "C-m") 'newline-and-indent)
                      )))
        '(
          clojure-mode-hook
          emacs-lisp-mode-hook
          erlang-mode-hook
          java-mode-hook
          js-mode-hook
          lisp-interaction-mode-hook
          lisp-mode-hook
          makefile-mode-hook
          nxml-mode-hook
          python-mode-hook
          ruby-mode-hook
          scheme-mode-hook
          sh-mode-hook
          ))

刚棒 scala-mode-hook在那里的某个地方，它也对你有用:)
