我使用 Mq 填充段落,我可以在自动填充模式下执行取消填充段落吗?
在 org 模式下,我有时会输入[[Very long HTML][Name with spaces]],对于“带空格的名称”,自动填充模式会根据插入的空格打破整行,这使得它非常难看。
是否有类似 un-fill-paragraph 的命令?或者,有没有办法暂时/本地禁用自动填充模式?
Emacs 不会记录您在调用之前的线路fill-paragraph
。所以你唯一能做的就是C-_运行命令撤消。它可以撤消您的fill-paragraph
命令,但前提是它是前面的命令调用。
如果您想将多行段落放在一行上,您可以这样做:
自从 monotux 的回答以来,Xah Lee 已经更新了他的代码,为了便于阅读,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 Org 模式下重新制作一段长行,我给了自己一个新命令。这是相关的 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
),它非常非常方便。我从 Xah Lee 那里借来了它,但删除了一些注释和空格以使其适合这里。第一条评论中的链接指向他的原始代码。

(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.
