opening a filename that appears in a buffer?

opening a filename that appears in a buffer?

[ljp]

Hello all,

I'm relatively new to emacs, and it is gradually becoming the central
fixture through which I do all of my programming.    One thing I find
myself doing often is executing a shell command in a shell buffer, and
then wanting to open a file that was listed in the output of the shell
command.   To do this right now I manually select the filename and
paste it into the minibuffer for C-x C-f.  Is there an easier way?
Like, maybe, a command that is able to pick out a filename from the
buffer when the cursor is in (but not necessarily at the start of)
that filename, and then open the file in a new buffer?

Thanks!  I've looked through documentation, but I haven't found
anything like this.

Yes, try M-x ffap, it does exactly what you want.

Just look for ffap in the Emacs manual.  Your desire is so common that
there is even a minor mode which redefines the standard bindings for
finding files.

Enjoy,

Yes, there is an easier way: ffap = find-file-at-point.

directly from my .emacs and its been there for a while so I dont know if
its the best way:

;; open file/url at point
(require 'ffap)
(ffap-bindings)
(add-to-list 'ffap-c-path "/usr/src/linux/include")
(add-to-list 'ffap-c-path "/usr/src/linux/include/linux")
(add-to-list 'ffap-c-path "/usr/include")
(add-to-list 'ffap-c-path "/usr/include/gtk-2.0")

Some extra tips:

change keybinding of M-x to M-a, so it's right under finger tip.

Change keybinding of M-! to Meta-shift-a, so that M-a is to execute
emacs cmd, and with shift down it runs a shell cmd.

Use alias to shortern the command “shell” to just “sh”.

The C-x C-f is to open a file, remap it to just M-f, since Meta is
right under thumb.

Give find-file-at-point a shortcut of Meta shift f. So that M-f is to
opens file, M-f with a dir path gives you dired, M-S-f opens the file
under cursor.

These are my personal settings. Here's code examples:

(defalias 'sh 'shell)

(global-unset-key (kbd "C-x C-f")) ; find-file
(global-unset-key (kbd "C-x d")) ; dired. (use find-file instead)

(global-set-key (kbd "M-f") 'find-file) ; was forward-word
(global-set-key (kbd "M-F") 'my-find-file-at-point) ; was nil

(global-set-key (kbd "M-a") 'execute-extended-command) ; was backward-
sentence
(global-set-key (kbd "M-A") 'shell-command)

i've also modified my ffap so that, when i view web logs which has
relative paths based on web root dir (as opposed the real root dir), i
can still use ffap to open the right file.

(defun my-find-file-at-point ()
 "Same as `find-file-at-point' but prepend path if root file.
If the path start with “/” and not "/Users/", then prepend it with “~/
web”."
 (interactive)
 (let (ff)
   (setq ff (thing-at-point 'filename))
   (when (and
          (equal "/" (substring ff 0 1))
          (not (equal "/Users/" (substring ff 0 7))))
     (setq ff (concat "~/web" ff)))
   (find-file ff)
   )
 )

I have several emacs tutorial on how to define arbitary keybindings,
and a full shortcut set based on ergonomic priciples. It's on my
website you might find interesting.
