在Emacs中重新定义ENTER键

Question

我不知道elisp,但我正在尝试做类似以下的事情:

(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ENTER键时调用这两个函数.我该怎么做呢？

Answer 1

我在很多模式中基本上都是这样做的,所以我把它们压在一起:

(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
          ))

只是坚持scala-mode-hook在某处,它也适合你:)

你需要一个(interactive)后形式lambda在你的define-key.

编辑:

要清楚,内部形式应如下所示:

(lambda ()
  (interactive)
  (scala-newline)
  (scala-indent-line))
