emacs新手问题-如何在区域内搜索

您可以使用以下命令组合:

M-x narrow-to-region
C-s SOMETEXT
M-x widen

不过,这有点麻烦,这里有一个新命令,可以自动为您执行上述操作。

(defun isearch-forward-region-cleanup ()
  "turn off variable, widen"
  (if isearch-forward-region
      (widen))
  (setq isearch-forward-region nil))

(defvar isearch-forward-region nil
  "variable used to indicate we're in region search")

(add-hook 'isearch-mode-end-hook 'isearch-forward-region-cleanup)

(defun isearch-forward-region (&optional regexp-p no-recursive-edit)
  "Do an isearch-forward, but narrow to region first."
  (interactive "P\np")
  (narrow-to-region (point) (mark))
  (goto-char (point-min))
  (setq isearch-forward-region t)
  (isearch-mode t (not (null regexp-p)) nil (not no-recursive-edit)))

现在就做吧

(global-set-key (kbd "C-S-s") 'isearch-forward-region)

正如特雷·杰克逊所说,你可以使用 narrow-to-region 和 widen . 我来凑钱买键盘快捷键。请注意,它们在默认情况下是禁用的,emacs将在第一次使用时以交互方式提示“取消禁用”它们。

C-x n n
C-s sometext
C-x n w
