问题:
I need to get the full path of the file that I'm editing with emacs.
- Is there a function for that?
- If not, what would be the elisp function for getting that?
- How can I copy the result (path name) to a clipboard so that I can reuse it?
I'm using Mac OS X and Aqumacs.
(setq filepath (get-fullpath-current-file)) ???
(copy-to-clipboard 'filepath) ???
ADDED
(defun show-file-name ()
"Show the full path file name in the minibuffer."
(interactive)
(message (buffer-file-name))
(kill-new (file-truename buffer-file-name))
)
(global-set-key "\C-cz" 'show-file-name)
Combining the two answers that I got, I could get what I want. Thanks for the answers. And some more questions.
- What's for (file-truename)?
- Can I copy the path name to System(OS)'s clipboard, not the kill ring so that I can use the info with the other apps?
回答1:
It's the built-in function buffer-file-name
that gives you the full path of your file.
The best thing to do is to have your emacs window to always show your system-name and the full path of the buffer you're currently editing :
(setq frame-title-format
(list (format "%s %%S: %%j " (system-name))
'(buffer-file-name "%f" (dired-directory dired-directory "%b"))))
You can also do something like this :
(defun show-file-name ()
"Show the full path file name in the minibuffer."
(interactive)
(message (buffer-file-name)))
(global-set-key [C-f1] 'show-file-name) ; Or any other key you want

To borrow from Jérôme Radix's answer, if you just want to quickly see the file path of the current buffer, you can do M-: buffer-file-name
.
回答3:
My trick is to do a C-x C-f
like to open a file, it wil prefill the minibuff with the current file path, C-g
to quit. Faster than M-: buffer-file-name
but far far uglier than any other methods.

The direct implementation of what you want is:
(defun copy-full-path-to-kill-ring ()
"copy buffer's full path to kill ring"
(interactive)
(when buffer-file-name
(kill-new (file-truename buffer-file-name))))
That said, I find it incredibly useful to be able to get the full path of what is in the minibuffer, and this is what I use:
(define-key minibuffer-local-completion-map "\C-r" 'resolve-sym-link)
(defun resolve-sym-link ()
"Try to resolve symbolic links into true paths."
(interactive)
(beginning-of-line)
(let* ((file (buffer-substring (point)
(save-excursion (end-of-line) (point))))
(file-dir (file-name-directory file))
(file-true-dir (file-truename file-dir))
(file-name (file-name-nondirectory file)))
(delete-region (point) (save-excursion (end-of-line) (point)))
(insert (concat file-true-dir file-name))))
And then if I want it in the clipboard, I just kill the line (C-a C-k). But we could easily copy the truename to the clipboard in the above command, just change the last line to be:
(insert (kill-new (concat file-true-dir file-name)))))
The new part is the call to 'kill-new
which puts the string in the kill ring.

No need for extra function, just
M-! pwd

I have the following code already in use for a long time.
It copies the full file path to the kill ring when I press the middle mouse button on the buffer name in the mode-line. It copies just the buffer name to the kill-ring when I press shift-mouse-2 on the buffer-name in the mode-line.
(defun copy-buffer-file-name (event &optional bufName)
"Copy buffer file name to kill ring.
If no file is associated with buffer just get buffer name.
"
(interactive "eP")
(save-selected-window
(message "bufName: %S" bufName)
(select-window (posn-window (event-start event)))
(let ((name (or (unless bufName (buffer-file-name)) (buffer-name))))
(message "Saved file name \"%s\" in killring." name)
(kill-new name)
name)))
(define-key mode-line-buffer-identification-keymap [mode-line mouse-2] 'copy-buffer-file-name)
(define-key mode-line-buffer-identification-keymap [mode-line S-mouse-2] '(lambda (e) (interactive "e") (copy-buffer-file-name e 't)))
回答7:
C-x C-d
, also callable via M-x list-directory
, will show you the directory for your current file, and you only need to hit the "Enter" key to clear the minibuffer. Additional details are available here.
回答8:
Can I copy the path name to System(OS)'s clipboard, not the kill ring so that I can use the info with the other apps?
You can if you shell out to something like xclip (Linux), pbcopy (Mac), putclip (Cygwin).
I personally use wrapper scripts c
and p
for copy and paste respectively, the first reading from standard input, the latter writing to standard output. That way, this works on all my development platforms:
(shell-command (format "echo '%s' | c" buffer-file-name))
I find this more reliable and configurable than using the Emacs clipboard support. For example, my c
command copies the input to all 3 clipboards on Linux (primary, secondary, clipboard), so I can paste with either Ctrl-V or middle click.
回答9:
C-x C-b
shows a list of buffers and the file path for each buffer where applicable.
回答10:
The simplest way and would be
(buffer-name)<(C-x)(C-e)> for the file name to appear in the echo area
(buffer-name)<(C-u)(C-x)(C-e)> would print the location <here>
Borrowing from Trey Jackson
I came up with this:
(defun buffer-kill-path ()
"copy buffer's full path to kill ring"
(interactive)
(kill-new (buffer-file-name)))

回答11:
copy-buffer-file-name-as-kill
from [0] does exactly what you need I think. It also has the option to copy just directory name, or just file name.
