我将 sr-speedbar 与 emacs 结合使用，并且我经常将框架拆分为 2-3 个不同的窗口，每当我在 sr-speedbar 中单击文件时，它总是在最下方的窗口中打开新缓冲区。我试图将最右下角的窗口保持为相对较小的 ansi-term，而 emacs 一直坚持在较小的 term 窗口中打开新缓冲区，而不是在我想用于编辑缓冲区的更大的区域中打开新缓冲区。
有没有什么方法可以配置缓冲区创建逻辑，使其优先选择较高的窗口而不是较低的窗口？
我已经尝试过将我最低的窗口标记为受保护，但这只会让 emacs 将其分成两个不合理的小部分。然后我尝试启用 window-size-fixed，它并没有让 emacs 打开该窗口上方的缓冲区，而是给了我一个错误，提示窗口太小而无法拆分。我想这很好，它停止破坏我最低的窗口，但它却阻止我打开新的缓冲区，这很愚蠢。
理想情况下，我希望能够强制 emacs 选择最右上角的窗口来显示新创建的缓冲区，而不是尝试分割最右下角的窗口。

我假设您使用的是 Emacs 24；我没有在任何早期版本中测试过这个答案，也不知道专用窗口的概念是什么时候添加到 Emacs 中的。我看到过关于其使用的提及，日期是 2011 年，所以我假设 Emacs 23（至少）也具有此功能。
您可以通过以下方式阻止 Emacs 在给定窗口中打开新缓冲区将窗口专用于其缓冲区。
在最简单的情况下，您可以通过选择要专用的窗口，确保它当前显示要专用的缓冲区，然后执行 来执行此操作M-: (set-window-dedicated-p (selected-window) t)。这将防止 Emacs 在决定在哪个窗口中显示缓冲区时考虑经过修改的窗口。要删除专用，请评估相同的表达式，将第二个参数替换为nil。
您可以通过将缓冲区局部变量 window-size-fixed 设置为非零值来阻止 Emacs 尝试拆分显示给定缓冲区的窗口。
在最简单的情况下，您可以通过选择窗口并执行 来做到这一点M-: (setq window-size-fixed t)。要仅修复显示缓冲区的窗口的高度或宽度，请计算相同的表达式，传递'height或'width作为第二个参数；要删除限制，请用 替换第二个参数nil。
一般情况下，我发现你的问题很有趣，想出解决办法，您可以将其放入加载路径，(require)并使用：

;;; Commentary:
;; Introduction
;; ============
;; The functions here defined allow you to manually dedicate and
;; undedicate windows, that is, prevent `set-window-buffer' from
;; considering them when selecting a window in which to display a
;; given buffer.
;; Windows dedicated in this fashion will also be protected from
;; splitting by setting `window-size-fixed'.
;; Installation
;; ============
;; Place this file in your load path; then, place the following
;; command somewhere in your initialization file:
;; (require 'dedicate-windows-manually)
;; Now you can use M-x dedicate-window to dedicate the selected window
;; to its currently displayed buffer, M-x undedicate-window to release
;; a dedication so applied, and M-x dedicate-window-toggle to switch
;; between the states.
;; These functions will operate only on manually dedicated or
;; undedicated windows; that is, M-x dedicate-window will not dedicate
;; a window which is already dedicated (i.e. "(window-dedicated-p
;; window) -> t", and M-x undedicate-window will not undedicate a
;; window which was not dedicated by way of M-x dedicate-window.
;; If you find yourself frequently doing M-x dedicate-window-toggle,
;; you might wish to place something like this in your init file:
;; (global-set-key (kbd "C-x 4 C-d") 'dedicate-window-toggle)
;; Bugs:
;; * Changing the lighter string while you have windows dedicated is
;; probably not a good idea.
;; * I should certainly find a better way to change the mode line.
;;; Code:
(defcustom dedicated-window-lighter-string " [D]"

答案2
在最近的 Emacs 版本中，display-buffer-alist添加了选项。它提供了对缓冲区显示、使用的窗口等的细粒度控制。但是，由于它允许您执行如此多的操作，因此它也相当复杂且难以描述。请参阅文档：C-h v display-buffer-alist。

我还可以推荐投入的模式。
