dired-x provides a method of visiting or editing a file mentioned in the buffer you are viewing (e.g., a mail buffer, a news article, a README file, etc.) or to test if that file exists. You can then modify this in the minibuffer after snatching the file name.
When installed dired-x will substitute
find-file (normally bound to C-x C-f) and
(normally bound to C-x 4 C-f).
In order to use this feature, you will need to set
nil before loading dired-x
(see Optional Installation File At Point).
dired-x-find-file behaves exactly like
find-file (normally bound
to C-x C-f) unless a prefix argument is passed to the function in which
case it will use the file name at point as a guess for the file to visit.
For example, if the buffer you were reading contained the words
Available via anonymous ftp in /roebling.poly.edu:/pub/lisp/crypt++.el.gz
then you could move your cursor to the line containing the ftp address and type C-u C-x C-f (the C-u is a universal argument). The minibuffer would read
Find file: /roebling.poly.edu:/pub/lisp/crypt++.el.gz
with the point after the last
/. If you hit RET, emacs will visit
the file at that address. This also works with files on your own computer.
dired-x-find-file-other-window behaves exactly like
find-file-other-window (normally bound to C-x 4 C-f) unless a
prefix argument is used. See
dired-x-find-file for more information.
If set to
t, then it means that dired-x should not bind
find-file on keyboard. Similarly, it
should not bind
find-file-other-window. If you change this variable after
dired-x.el is loaded then do M-x dired-x-bind-find-file. The
default value of this variable is
t; by default, the binding is not
done. See Optional Installation File At Point.
A function, which can be called interactively or in your ~/.emacs file,
that uses the value of
dired-x-hands-off-my-keys to determine if
dired-x-find-file should be bound over
dired-x-find-file-other-window bound over
find-file-other-window. See Optional Installation File At Point.
