Question

我使用M-q作为fill-paragraph，我可以在自动填充模式下执行un-fill-paragraph吗？

使用组织模式，我有时会输入 [[很长的HTML] [带空格的名称]] ，对于'带空格的名称'，自动填充模式会根据插入空间，这使它非常难看。

是否有类似un-fill-paragraph的命令？或者，有没有办法临时/本地禁用自动填充模式？

Answer 1

在调用fill-paragraph之前，Emacs不记录您的行。所以你唯一能做的就是运行命令undo的 C -_ 。它可以撤消您的fill-paragraph命令，但前提是它只是前面的命令调用。

如果你想在一行上放一个多行段落，你可以这样做：

选择区域
CM - ％ Cq Cj RET SPACE RET < / kbd> ！

自从monotux的答案以来，Xah Lee已经更新了他的代码，并且为了可读性我进行了一些重构：

(defun my-toggle-fill-paragraph ()
  ;; Based on http://xahlee.org/emacs/modernization_fill-paragraph.html
  "Fill or unfill the current paragraph, depending upon the current line length.
When there is a text selection, act on the region.
See `fill-paragraph' and `fill-region'."
  (interactive)
  ;; We set a property 'currently-filled-p on this command's symbol
  ;; (i.e. on 'my-toggle-fill-paragraph), thus avoiding the need to
  ;; create a variable for remembering the current fill state.
  (save-excursion
    (let* ((deactivate-mark nil)
           (line-length (- (line-end-position) (line-beginning-position)))
           (currently-filled (if (eq last-command this-command)
                                 (get this-command 'currently-filled-p)
                               (< line-length fill-column)))
           (fill-column (if currently-filled
                            most-positive-fixnum
                          fill-column)))

      (if (region-active-p)
          (fill-region (region-beginning) (region-end))
        (fill-paragraph))

      (put this-command 'currently-filled-p (not currently-filled)))))

要在Org模式中重新创建段落中的长行，我给自己一个新命令。以下是相关的Emacs Lisp代码：

(defun fp-unfill-paragraph (&optional justify region)
  (interactive (progn
         (barf-if-buffer-read-only)
         (list (if current-prefix-arg 'full) t)))
  (interactive)
  (let ((fill-column 100000))
    (fill-paragraph justify region)))

(global-set-key "\C-ceu" 'fp-unfill-paragraph)

当然，您可以根据需要调整命令键绑定！

我使用以下代码段来填充和取消填充段落（仅使用M-q），这非常非常方便。我是从Xah Lee那里借来的，但删除了一些评论和空白以使其适合这里。第一条评论中的链接转到他的原始代码。

;; http://xahlee.org/emacs/modernization_fill-paragraph.html
(defun compact-uncompact-block ()
  "Remove or add line endings on the current block of text.
This is similar to a toggle for fill-paragraph and unfill-paragraph
When there is a text selection, act on the region.

When in text mode, a paragraph is considered a block. When in programing
language mode, the block defined by between empty lines.

Todo: The programing language behavior is currently not done.
Right now, the code uses fill* functions, so does not work or work well
in programing lang modes. A proper implementation to compact is replacing
newline chars by space when the newline char is not inside string.
"
  (interactive)
  (let (bds currentLineCharCount currentStateIsCompact
            (bigFillColumnVal 4333999) (deactivate-mark nil))
    (save-excursion
      (setq currentLineCharCount
            (progn
              (setq bds (bounds-of-thing-at-point 'line))
              (length (buffer-substring-no-properties (car bds) (cdr bds)))))
      (setq currentStateIsCompact
            (if (eq last-command this-command)
                (get this-command 'stateIsCompact-p)
              (if (> currentLineCharCount fill-column) t nil)))
      (if (and transient-mark-mode mark-active)
          (if currentStateIsCompact
              (fill-region (region-beginning) (region-end))
            (let ((fill-column bigFillColumnVal))
              (fill-region (region-beginning) (region-end)))
            )
        (if currentStateIsCompact
            (fill-paragraph nil)
          (let ((fill-column bigFillColumnVal))
            (fill-paragraph nil))))
      (put this-command 'stateIsCompact-p
           (if currentStateIsCompact
               nil t)))))
(global-set-key (kbd "M-q") 'compact-uncompact-block)

使用emacs在本地（或un fill-paragraph）禁用自动填充模式
