在一个缓冲区中将点移动到与不同缓冲区中的点相同的行号 [英] Move point in one buffer to the same line number as the point in a different buffer

问题描述

问题：我有两个缓冲区分开并排。我移动到左侧缓冲区中的一行，并且我想要执行某些，将正确的缓冲区中的点移动到相同的行号。例如，如果我在左侧缓冲区中的第26行，我运行一些宏，瞧我在正确的缓冲区上的第26行。

The problem: I have two buffers split side-by-side. I move to a line in the left buffer and I want to do something which moves the point in the right buffer to the same line number. For example, if I'm on line 26 in the left buffer I run a macro of some kind and voila I'm on line 26 on the right buffer.

我试过哪些没有像我喜欢的那样工作（或者根本就没有）：

Things I've tried which haven't worked as I liked (or at all):

• scroll-all-模式。如果缓冲区同步开始（例如，两个缓冲区中的位置在同一行号上），并且如果我坚持基本行移动，它将起作用。但是，如果我 isearch-forward-regexp 或者page-up / page-down，它会很快失去同步。如果有一个可以重新同步的命令，那么这解决了我的问题。


• 将当前行号保存在寄存器中，并在 goto-line 。保存和恢复位置总是回到相同的缓冲区。

• scroll-all-mode. It works if the buffers are in sync to begin with (e.g. point is on the same line number in both buffers) and if I stick to basic line movement. But it quickly loses sync if I isearch-forward-regexp or page-up/page-down. If there was a command which could "resync" then this solves my problem.
• Saving current line number in a register and using that register value in goto-line. Saving and restoring positions always goes back to the same buffer.

推荐答案

这块Emacs Lisp应该做你想要的：

This piece of Emacs Lisp should do what you want:

(goto-line (line-number-at-pos) (window-buffer (next-window))

要绑定到一个键序列，

(global-set-key (kbd "C-c l")
  (lambda ()
    (interactive)
    (goto-line (line-number-at-pos) (window-buffer (next-window)))))
