Question

我正在使用带有cc模式的emacs24，我想知道如何使我的emacs更“聪明”。输入}后，它将自动插入一个新行并缩进为例外。我想知道如何将点切换到上一行。例如，当我定义一个函数时，现在我的emacs行为是：

void f()
{
}
//point

“// point”是输入}后光标的位置。但我想要的是：

void f()
{
    //point
}

我希望光标的位置可以切换到上一行并自动缩进。我知道emacs可以做到这一点，但我不知道怎么做，谁能帮帮我？

Answer 1

我认为你是在追踪这些...... C-M-u，C-M-d，C-M-f和C-M-b

练习一点......他们是一种全球性的，他们几乎在所有模式中都表现出上下文。

更新：

哦..似乎你想自动放置光标..实际上，更常见的Emacs将帮助你根本不输入}。我的意思是emacs可以自动插入关闭paran。

有一个内置的电对模式

第三方 autopair.el

我不相信任何电动，所以我写了这个功能。

(defconst insert-logical-brackets-logical-bracket-begin "{")
(defconst insert-logical-brackets-logical-bracket-end "}")
(defconst insert-logical-brackets-default-style 0)
(make-variable-buffer-local 'logical-bracket-begin)
(make-variable-buffer-local 'logical-bracket-end)
(make-variable-buffer-local 'insert-logical-brackets-default-style)
(defun insert-logical-brackets(&optional style)
  "If STYLE = 0(default, according to `insert-logical-brackets-default-style' value), make a newline before opening bracket, if line is not empty. Make a newline after closing bracket, if there is something after this bracket. Make two newlines in the middle.
If STYLE = 1, don't make newlines before opening a bracket(one of c styles).
If STYLE = 2, don't make newlines before opening and after closing bracket.
If STYLE = 3, allways make all newlines.
If STYLE is not nil, don't make newlines between brackets(still makes before/after lines)."
  (interactive "P")
  (when (eq style nil)
    (setq style insert-logical-brackets-default-style))
  (funcall indent-line-function)
  (unless (or (eq 1 style) (eq 2 style))
    (when (or (/= (point) (save-excursion (back-to-indentation) (point))) (eq 3 style))
      (newline)
      (funcall indent-line-function)))
  (unless (and (integerp style) (= 2 style))
    (when (or (not (looking-at "\n")) (eq 3 style))
      (newline)
      (funcall indent-line-function)
      (forward-line -1)
      (goto-char (point-at-eol))))
  (insert logical-bracket-begin)
  (funcall indent-line-function)
  (let ((return-point (point)))
    (when (or (not style) (or (eq 0 style) (eq 1 style) (eq 2 style) (eq 3 style)))
      (newline)
      (funcall indent-line-function)
      (setq return-point (point))
      (newline))
    (insert logical-bracket-end)
    (funcall indent-line-function)
    (goto-char return-point)))
