将Emacs设置为并排拆分缓冲区

Question

许多Emacs功能会自动拆分屏幕。然而，它们都这样做，使得窗户一个在另一个之上。是否有任何方法可以将它们分开，以便它们默认并排？

Answer 1

(setq split-height-threshold nil)
(setq split-width-threshold 0)

GNU Emacs Lisp参考手册：Choosing Window Options

Answer 2

这里有两个解决方案，使用你喜欢的任何一个：

答：默认情况下垂直（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）分割窗口

(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)

将任何一个放入.emacs/init.el文件中。 您可以将“100”更改为您喜欢的值，具体取决于您的屏幕。

如果您在一个框架中有两个窗口，并且您想要将布局从垂直更改为水平或反之，那么这是一个解决方案：

(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.emacs/init.el文件中，使用C-x 4 t切换窗口布局。

Answer 3

(setq split-height-threshold 0) (setq split-width-threshold 0)

是我必须用来获得所需行为（没有水平分割）

Answer 4

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更改。

我推荐伟大的ToggleWindowSplit，并将键绑定到“C-c y”

Answer 5

将2个变量设置为nil和0的简单答案对我来说不起作用，所以我编写了2个简单函数：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在每个和另一个中做同样的想法，除了在2D中（NY行由NX列打开文件f.1 f.2 ... f。[NX * NY]）。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)
          )
        )
      )

然后使用垂直的，我转到* 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 one，C-x 1，输入(grid-files-sq 2 15 3 20 "f.")然后C-x C-e，你会看到像

这可能可以更好/更有效地完成，但它是一个开始，它做我需要它做的事情（显示一堆顺序命名的小文件）。随意改进或重用。

我经常在emacs中为不同的项目使用多个帧（OSX窗口）。这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")
