如何使基于文件名的emacs自动命名缓冲区？

Question

I often load many 00readme.txt files into emacs, and the default buffer name "00readme.txt" isn't very helpful.

I use rename-buffer manually to rename them "project1", "project2", etc.

How do I tell emacs: "when loading /foo/bar/00readme.txt, automatically name the buffer project1, not 00readme.txt"?

Answer 1

您可能还需要查看emacs附带的uniquify库，当打开具有相同名称的文件时，该库可以将部分目录名称添加到缓冲区名称中。

Answer 2

;; toss this into your .emacs file and fiddle with it till you get what you want
(defun my-buffer-renamer() 
(interactive) 
(let ()  ; <--  local vars in here

  (message "bufer name is %s" (current-buffer))
  (rename-buffer "something else") ; make sure to make unique names

))

(add-hook 'text-mode-hook 'my-buffer-renamer) ; only do this once

Emacs supports a plethora of 'hook' functions, callbacks that get executed when a particular action occurs. Here, we add a function to gets invoked when a text file get's loaded.

Here's a nice configuration for uniquify , which is the standard Emacs way to solve your problem:

(require 'uniquify)
(setq uniquify-buffer-name-style 'reverse)
      uniquify-separator " • "
      uniquify-after-kill-buffer-p t
      uniquify-ignore-buffers-re "^\\*"
