Emacs 可怕的行为

发布于 2024-10-20 15:42:58 字数 168 浏览 5 评论 0原文

我已经使用 emacs 多年，并且习惯于让 emacs 在执行 dired 的同一窗口中打开选定的文件。在最近的修订中，当在打开 2 个窗口的情况下执行 dired 时，选定的文件将显示在备用窗口中从迪雷德。如何设置 emacs 使用相同的窗口来显示已死亡的文件（允许我同时查看两个文件 - emacs 过去的工作方式）？

根据上面的评论，在 dired 中检查 ChkRET 来查看 RET 绑定到什么（或者如果您使用另一个密钥，则类似）。

dired-find-file 使用 switch-to-buffer 这可能会导致缓冲区在另一个窗口中打开：

如果所选窗口是迷你缓冲区窗口或专用于
它的缓冲区，使用“pop-to-buffer”来显示缓冲区。

不过，这似乎不太可能成为问题。

编辑：啊，你正在使用鼠标。在有关 Emacs 的问题中明确说明这一点通常是件好事，因为大多数 Emacs 用户很少接触鼠标。

然而，同样的答案也适用：从 dired 中，输入 Chk ，然后输入您正在使用的“键”绑定（在本例中单击鼠标按钮 1），它告诉我们：

----------------- 向上事件（短按）----------------
<鼠标-1>;在该位置被重新映射到，它运行
命令 dired-mouse-find-file-other-window，这是一个交互式命令
在 `dired.el' 中编译了 Lisp 函数。
（定向鼠标查找文件其他窗口事件）
在 Dired 中，访问您单击的文件或目录名称。

由于某种原因，没有默认的 dired-mouse-find-file 函数，但以下代码会伪造它：

(add-hook 'dired-mode-hook 'my-dired-mode-hook)
(defun my-dired-mode-hook ()
  (local-set-key (kbd "<mouse-2>") 'dired-mouse-find-file))

(defun dired-mouse-find-file (event)
  "In Dired, visit the file or directory name you click on."
  (interactive "e")
  (require 'cl)
  (flet ((find-file-other-window
          (filename &optional wildcards)
          (find-file filename wildcards)))
    (dired-mouse-find-file-other-window event)))

As per the comments above, check C-hkRET when in dired to see what RET is bound to (or similarly if you are using another key).

dired-find-file uses switch-to-buffer which could cause the buffer to open in another window:

If the selected window is the minibuffer window or dedicated to
its buffer, use `pop-to-buffer' for displaying the buffer.

That seems less likely to be the issue, though.

edit: Ah, you're using the mouse. It's often good to explicitly say that in questions about Emacs, because most Emacs users rarely touch the mouse.

The same answer applies, however: From dired, type C-hk and then the 'key'-binding you are using (in this case clicking mouse button 1), which tells us:

----------------- up-event (short click) ----------------
<mouse-1> at that spot is remapped to <mouse-2>, which runs the
command dired-mouse-find-file-other-window, which is an interactive
compiled Lisp function in `dired.el'.
(dired-mouse-find-file-other-window EVENT)
In Dired, visit the file or directory name you click on.

There's no default dired-mouse-find-file function for some reason, but the following will fake it:

(add-hook 'dired-mode-hook 'my-dired-mode-hook)
(defun my-dired-mode-hook ()
  (local-set-key (kbd "<mouse-2>") 'dired-mouse-find-file))

(defun dired-mouse-find-file (event)
  "In Dired, visit the file or directory name you click on."
  (interactive "e")
  (require 'cl)
  (flet ((find-file-other-window
          (filename &optional wildcards)
          (find-file filename wildcards)))
    (dired-mouse-find-file-other-window event)))
