如何在信息模式下打开emacs中的* .info文件？

Question

Cx Cf blah.info opens the file in fundametal mode. I used apropos and found Info-mode which I thought might change from fundamental mode into Info mode, but that throws a lisp error.

How can I open a external/thirdparty *.info file in emacs so that I get the same bells and whistles as when I'm looking at Mx info ( n for next, u for up, hyperlinks, etc..)? I'm sure this is obvious, but I can't figure it out.

Answer 1

尝试Cu Ch i （即通常的带有前缀参数的信息调用）。

Answer 2

Plain (info `file-name') opens file in info mode. (info) probably does something besides just setting Info-mode. So I would use something like this:

(defun info-mode ()
  (interactive)
  (let ((file-name (buffer-file-name)))
    (kill-buffer (current-buffer))
    (info file-name)))
(add-to-list 'auto-mode-alist '("\\.info\\'" . info-mode))

Answer 3

When your cursor is on the filename in the dired buffer, press I ( shift and i ). Requires dired-x, which is part of GNU Emacs.

I runs the command dired-info
  which is an interactive compiled Lisp function in `dired-x.el'.
It is bound to I.
(dired-info)

Run info on this file.

Answer 4

You can use org mode . Type the following in a buffer already set using Mx org-mode :

info:path/to/blah

Then invoke info by placing the cursor over this and hitting Cc Co . Alternatively, click on it with your mouse. You can also set the whole thing in double square brackets, if you path contains whitespace.

Answer 5

(add-to-list 'auto-mode-alist '("\\.info\\'" . Info-on-current-buffer))

Answer 6

Add the following to your .emacs initialization file:

(setq auto-mode-alist 
      (append '(("\\.info" . Info-mode)) auto-mode-alist))
