很多 Emacs 功能会自动分屏。但是，它们都这样做是为了使窗户一个在另一个之上。有没有办法让它们分开，默认情况下它们是并排的？

(setq split-height-threshold nil)
(setq split-width-threshold 0)
GNU Emacs Lisp 参考手册：Choosing Window Options
【讨论】：
这里有两种解决方案，使用任何你喜欢的方法：
A：默认垂直（左/右）：
(setq split-height-threshold nil)
(setq split-width-threshold 0)
B：如果当前窗口足够宽，则自动垂直（左/右）拆分窗口
(defun display-new-buffer (buffer force-other-window)
"If BUFFER is visible, select it.
If it's not visible and there's only one window, split the
current window and select BUFFER in the new window. If the
current window (before the split) is more than 100 columns wide,
split horizontally(left/right), else split vertically(up/down).
If the current buffer contains more than one window, select
BUFFER in the least recently used window.
This function returns the window which holds BUFFER.
FORCE-OTHER-WINDOW is ignored."
(or (get-buffer-window buffer)
(if (one-window-p)
(let ((new-win
(if (> (window-width) 100)
(split-window-horizontally)
(split-window-vertically))))
(set-window-buffer new-win buffer)
new-win)
(let ((new-win (get-lru-window)))
(set-window-buffer new-win buffer)
new-win))))
;; use display-buffer-alist instead of display-buffer-function if the following line won't work
(setq display-buffer-function 'display-new-buffer)
把任何一个放在你的.emacs/init.el文件里。
您可以将“100”更改为您喜欢的值，具体取决于您的屏幕。
如果您在一帧中有两个窗口，并且您想将布局从垂直更改为水平或反之，这是一个解决方案：
(defun toggle-window-split ()
(interactive)
(if (= (count-windows) 2)
(let* ((this-win-buffer (window-buffer))
(next-win-buffer (window-buffer (next-window)))
(this-win-edges (window-edges (selected-window)))
(next-win-edges (window-edges (next-window)))
(this-win-2nd
(not (and (<= (car this-win-edges)
(car next-win-edges))
(<= (cadr this-win-edges)
(cadr next-win-edges)))))
(splitter
(if (= (car this-win-edges)
(car (window-edges (next-window))))
'split-window-horizontally
'split-window-vertically)))
(delete-other-windows)
(let ((first-win (selected-window)))
(funcall splitter)
(if this-win-2nd (other-window 1))
(set-window-buffer (selected-window) this-win-buffer)
(set-window-buffer (next-window) next-win-buffer)
(select-window first-win)
(if this-win-2nd (other-window 1))))))
;; C-x 4 t 'toggle-window-split
(define-key ctl-x-4-map "t" 'toggle-window-split)
将其放入您的.emacs/init.el 文件中，使用C-x 4 t 切换窗口的布局。

undo-tree 时在解决方案视图中按q 不会排除缓冲区
(setq split-height-threshold 0) (setq split-width-threshold nil)
(setq split-height-threshold 0) (setq split-width-threshold 0)
是我必须用来获得所需行为（无水平分割）
【讨论】：
有时我们需要根据当前显示和我们的要求（更多行或更多列）在水平和垂直之间进行切换。
我推荐伟大的ToggleWindowSplit，我将键绑定到“C-c y”

将 2 个变量设置为 nil 和 0 的简单答案对我不起作用，因此我编写了 2 个简单的函数：一个只是将窗口拆分为 NX 垂直缓冲区并打开名为（例如）file.1 文件的文件。 2 ... file.NX 在每个和另一个中都有相同的想法，除了它在 2D 中（用于打开文件 f.1 f.2 ... f.[NX*NY] 的 NX 列的 NY 行）。要安装，请将此代码添加到 .emacs：
(defun grid-files-h (nx wx pfx)
"Using dotimes, split the window into NX side-by-side buffers of width WX and load files starting with prefix PFX and ending in numbers 1 through NX"
(let (ox fn k) ; ox is not used, but fn is used to store the filename, and k to store the index string
(dotimes (x (- nx 1) ox) ; go through buffers, x goes from 0 to nx-2 and ox is not used here
; (print x)
(setq k (number-to-string (+ x 1) ) ) ; k is a string that goes from "1" to "nx-1"
; (print k)
(setq fn (concat pfx k) ) ; fn is filename - concatenate prefix with k
; (print fn)
(find-file fn) ; open the filename in current buffer
(split-window-horizontally wx) ; split window (current buffer gets wx-columns)
(other-window 1) ; switch to the next (right) buffer
)
(setq k (number-to-string nx )) ; last (rightmost) buffer gets the "nx" file
(setq fn (concat pfx k) ) ; fn = "pfx"+"nx"
(find-file fn ) ; open fn
(other-window 1) ; go back to the first buffer
)
)
(defun grid-files-sq (ny wy nx wx pfx)
"Using dotimes, split the window into NX columns of width WX and NY rows of height WY and load files starting with prefix PFX and ending in numbers 1 through NX*NY"
(let (oy ox fn k)
(dotimes (y ny oy) ; go through rows, y goes from 0 to ny-1 and oy is not used here
(split-window-vertically wy) ; create this row
(dotimes (x (- nx 1) ox) ; go through columns, x goes from 0 to nx-2 and ox is not used here
(setq k (number-to-string (+ 1 (+ x (* y nx) ) ) ) ) ; k must convert 2 indecies (x,y) into one linear one (like sub2ind in matlab)
(setq fn (concat pfx k) ) ; filename
(find-file fn ) ; open
(split-window-horizontally wx) ; create this column in this row (this "cell")
(other-window 1) ; go to the next buffer on the right
)
(setq k (number-to-string (+ nx (* y nx) ) ) ) ; rightmost buffer in this row needs a file too
(setq fn (concat pfx k) ) ; filename
(find-file fn ) ; open
(other-window 1) ; go to next row (one buffer down)
)
)
)
然后要使用垂直的，我去 *scratch* (C-x b *scratch* RET,C-x 1)，输入 (grid-files-h 3 20 "file.") 然后 C-x C-e，或者如果你想测试方形 qrid 一个，@ 987654327@，输入(grid-files-sq 2 15 3 20 "f.")，然后输入C-x C-e，你应该会看到类似
这可能可以做得更好/更有效，但这是一个开始，它完成了我需要做的事情（显示一堆按顺序命名的小文件）。随意改进或重复使用。

我经常在 emacs 中为不同的项目使用多个框架（OSX 窗口）。以下是我如何设置最初拆分为左右窗口的几帧。
(defun make-maximized-split-frame (name)
(let (( f (make-frame (list (cons 'name name))) ))
(maximize-frame f)
(split-window (frame-root-window f) nil t)
))
(make-maximized-split-frame "DocRaptor")
(make-maximized-split-frame "Gauges")
(make-maximized-split-frame "Instrumental")

直接回答是按C-c 3。
从问题中不清楚您是否想要永久更改设置，但我发现这个问题正在寻找这个答案，但没有找到。 （答案实际上在过去 11 年一直在评论中）
