我使用ViewSourceWith 和 Emacs编辑我的 StackOverflow 答案和问题。通常,我包含代码并且StackOverflow 格式规则 说它必须缩进四个空格才能被识别为这样。手动甚至使用宏都是痛苦的。
我搜索了 SO 以前的帖子,但一无所获。
从 Python 模式开始,我写道:
(defun text-shift-region (start end count)
"Indent lines from START to END by COUNT spaces."
(save-excursion
(goto-char end)
(beginning-of-line)
(setq end (point))
(goto-char start)
(beginning-of-line)
(setq start (point))
(indent-rigidly start end count)))
(defun text-shift-region-right (start end &optional count)
"Shift region of code to the right
Stolen from python-mode.
The lines from the line containing the start of the current region up
to (but not including) the line containing the end of the region are
shifted to the right, by `text-indent-offset' columns.
If a prefix argument is given, the region is instead shifted by that
many columns. With no active region, indent only the current line."
(interactive
(let ((p (point))
(m (mark))
(arg current-prefix-arg))
(if m
(list (min p m) (max p m) arg)
(list p (save-excursion (forward-line 1) (point)) arg))))
(text-shift-region start end (prefix-numeric-value
(or count text-indent-offset)))
)
;; Code in StackOverflow must be marked by four spaces at the
;; beginning of the line
(setq text-indent-offset 4)
(global-set-key "\C-c>" 'text-shift-region-right)
它似乎有效,但我欢迎建议、替代方案、错误报告等。
