c++ - emacs 中 javadoc 样式注释的格式化

Question

我们需要使用 javadoc 格式的 doxygen 注释来注释我们的 C++ 代码，我正在 emacs 中寻找可以在我键入时保持 javadoc 风格的东西。

所以如果我开始写这样的评论:

/**
 * This function does the following:

当我点击“回车”时，我希望光标自动缩进并插入一个“*”，这样我就可以继续输入而无需手动格式化。因此，当我点击“返回”时，评论现在应该看起来像这样(无需输入“[TAB]*”):

/**
 * This function does the following:
 *

在这里找到答案:http://www.frankmeffert.de/2010/09/emacs-doxygen-doxymacs/我做了一些细微的调整以适用于 C 和 C++ 模式，并在每个“*”之后添加了一个额外的空格

(defun my-javadoc-return () 
  "Advanced C-m for Javadoc multiline comments.   
Inserts `*' at the beggining of the new line if 
unless return was pressed outside the comment"
  (interactive)
  (setq last (point))
  (setq is-inside
        (if (search-backward "*/" nil t)
        ;; there are some comment endings - search forward
            (search-forward "/*" last t)
          ;; it's the only comment - search backward
          (goto-char last)
          (search-backward "/*" nil t)
      )
    )
  ;; go to last char position
  (goto-char last)
  ;; the point is inside some comment, insert `* '
  (if is-inside
      (progn 
    (insert "\n* ")
    (indent-for-tab-command))
    ;; else insert only new-line
    (insert "\n")))

(add-hook 'c-mode-common-hook (lambda () 
  (local-set-key "\r" 'my-javadoc-return)))
