如何更改分屏 emacs 窗口的大小？

我将 emacs 水平分割 - 在顶部我正在编辑 Perl 代码，底部是 shell。默认情况下，emacs 使两个窗口大小相等，但我希望 shell 缓冲区更小（也许是一半大小？）。我想知道我怎样才能做到这一点。

使用鼠标，您可以拖动窗口大小。

单击模式线上非“活动”的任意位置（缓冲区名称是安全的，或右侧任何未使用的区域），然后可以向上或向下拖动。

左右拖动需要非常精确地单击两条模式线的连接点。

C-x - (shrink-window-if-larger-than-buffer) will shrink a window to fit its content.

C-x + (balance-windows) will make windows the same heights and widths.

C-x ^ (enlarge-window) increases the height by 1 line, or the prefix arg value. A negative arg shrinks the window. e.g. C-- C-1 C-6 C-x ^ shrinks by 16 rows, as does C-u - 1 6 C-x ^.

（没有默认绑定shrink-window.)

C-x } (enlarge-window-horizontally) does likewise, horizontally.
C-x { (shrink-window-horizontally) is also bound by default.

Following one of these commands with repeat (C-x z to initiate, and just z for continued repetition) makes it pretty easy to get to the exact size you want.

如果您经常想要使用特定值执行此操作，您可以录制键盘宏来执行此操作，或者使用类似
(global-set-key (kbd "C-c v") (kbd "C-u - 1 6 C-x ^"))

Or this:
(global-set-key (kbd "C-c v") (kbd "C-x o C-x 2 C-x 0 C-u - 1 C-x o"))

这是一个有点 hacky，所以这会更好：

(defun halve-other-window-height ()
  "Expand current window to use half of the other window's lines."
  (interactive)
  (enlarge-window (/ (window-height (next-window)) 2)))

(global-set-key (kbd "C-c v") 'halve-other-window-height)

Tangentially, I also love winner-mode which lets you repeatedly 'undo' any changes to window configurations with C-c left (whether the change is the size/number/arrangement of the windows, or just which buffer is displayed). C-c right returns you to the most recent configuration. Set it globally with (winner-mode 1)
