使用emacs在本地禁用自动填充模式(或取消填充段落)

Emacs不会在呼叫之前记录您的线路 fill-paragraph . 所以你唯一能做的就是 C-- 它运行命令undo。它可以撤销您的 填充段落 命令,但仅当它是前面的命令调用时。

如果要在一行上放置多行段落,可以这样做:

• 选择区域
• C-M%% C-Q C-J 雷特 空间 雷特 !

XahLee在Monotux的回答之后更新了他的代码,为了可读性,我对其进行了一些重构:

(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)))))

为了在组织模式下从一个段落中重排一行,我给了自己一个新的命令。以下是关联的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!

我使用以下代码段填充和取消填充段落(仅使用 M-q )真的,真的很方便。我从xah-lee那里借了它,但是删除了一些注释和空白以使它适合这里。第一条注释中的链接指向他的原始代码。

;; 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.
