根据Filling上的手动节点,一些fill函数采用一个可选的JUSTIFY参数,您可以使用该参数。因此,例如,要使用正确的理由填充段落,可以使用(fill-paragraph 'right)
。
您也可以使用(justify-current-line 'right)
单行。
如果计划大量使用这些选项,则可以将它们包装在如下函数中,然后将这些函数绑定到您选择的键上:
(defun right-justify-current-line ()
"Right-justify this line."
(interactive)
(justify-current-line 'right))
(defun right-fill-paragraph ()
"Fill paragraph with right justification."
(interactive)
(fill-paragraph 'right))
您可以使用以下函数代替fill-paragraph
。使用各种前缀,它可以让您决定在要填充的段落上使用哪种对齐方式:
(defun fill-paragraph-dwim (&optional arg)
"Fills the paragraph as normal with no prefix. With C-u,
right-justify. With C-u C-u, center-justify. With C-u C-u C-u,
full-justify."
(interactive "p")
(fill-paragraph (cond ((= arg 4) 'right)
((= arg 16) 'center)
((= arg 64) 'full))))
如果您不希望在右对齐时进行填充,则可以使用以下函数,该函数直接通过center-region
单行更改从函数中复制,以使其右对齐:
(defun right-region (from to)
"Right-justify each nonblank line starting in the region."
(interactive "r")
(if (> from to)
(let ((tem to))
(setq to from from tem)))
(save-excursion
(save-restriction
(narrow-to-region from to)
(goto-char from)
(while (not (eobp))
(or (save-excursion (skip-chars-forward " \t") (eolp))
;; (center-line)) ; this was the original code
(justify-current-line 'right)) ; this is the new code
(forward-line 1)))))
