I want to open a pdf with evince instead of DocView mode. Is there a possibility to open a file with开发者_开发技巧 a specific command like 'evince'?
Yes. Use !
while in dired to run a shell command on a file.
In the case of evince
, it's smarter to use &
, though, which will run the command asynchronously, so emacs will still be usable while you have the PDF open.
There is more then one way to do that. I suggest OpenWith library. Setup for your case may look like that:
(add-to-list 'load-path "/path/to/downloaded/openwith.el")
(require 'openwith)
(setq openwith-associations '(("\\.pdf\\'" "evince" (file))))
(openwith-mode t)
It sets file handler that will work from both dired
and find-file
.
Try this.
(defun dired-open-file ()
"In dired, open the file named on this line."
(interactive)
(let* ((file (dired-get-filename nil t)))
(message "Opening %s..." file)
(call-process "gnome-open" nil 0 nil file)
(message "Opening %s done" file)))
You can use !
to open the file and then specify a command.
Note that you can keep the process alive after exiting Emacs by using nohup
[Wikipedia], so put the point on a single file in dired
:
C-u ! nohup evince ? &
which creates a Persistent Processes [EmacsWiki].
In Windows, I offen use ! and command "explorer" to open PDF/Word/Excel...
(defun dired-open()
(interactive)
(setq file (dired-get-file-for-visit))
(setq ext (file-name-extension file))
(cond ((string= ext "pdf")
;; shell-quote-argument escapes white spaces on the file name
(async-shell-command (concat "zathura " (shell-quote-argument file))))
((string= ext "epub")
(async-shell-command (concat "zathura " (shell-quote-argument file))))
((string= ext "rar")
(async-shell-command (concat "file-roller " (shell-quote-argument file))))
((string= ext "zip")
(async-shell-command (concat "file-roller " (shell-quote-argument file))))
(t (dired-find-file))))
