如何在执行当前缓冲区时在emacs中水平分割窗口？

Question

我在使用Emacs的python编码。我修改了“.emacs”以适应我的需求。但是，我不知道如何在执行当前缓冲区时更改窗口的默认垂直拆分行为。

我知道：

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

的作品一般。但是，当我使用C-c C-c

首次执行缓冲尽管有在我的〜/的.emacs上面的代码中这是行不通的，下面发生在C-c C-c：

我希望我的问题是清楚的，让我知道你是否有任何想法。

我使用以下内容。它修复了你的问题（我希望），以及防止Emacs首先分裂窗口。

;;; ------------------------------------------------------------------ 
;;; display-buffer 

;; The default behaviour of `display-buffer' is to always create a new 
;; window. As I normally use a large display sporting a number of 
;; side-by-side windows, this is a bit obnoxious. 
;; 
;; The code below will make Emacs reuse existing windows, with the 
;; exception that if have a single window open in a large display, it 
;; will be split horisontally. 

(setq pop-up-windows nil) 

(defun my-display-buffer-function (buf not-this-window) 
    (if (and (not pop-up-frames) 
      (one-window-p) 
      (or not-this-window 
       (not (eq (window-buffer (selected-window)) buf))) 
      (> (frame-width) 162)) 
     (split-window-horizontally)) 
    ;; Note: Some modules sets `pop-up-windows' to t before calling 
    ;; `display-buffer' -- Why, oh, why! 
    (let ((display-buffer-function nil) 
     (pop-up-windows nil)) 
    (display-buffer buf not-this-window))) 

(setq display-buffer-function 'my-display-buffer-function)
