drag-n-drop support

thanks for giving this a try!

should I do anything except for loading this contrib file? it didn't
seem to work for me on first try, I just get the file contents
inserted as text into the mail buffer. The mac (ns) port may be
behaving differently, there is this [ns-drag-file] that needs to be
defined or used, perhaps?

Drag and drop is now in revision 1060. (It was easier than I expected!)

hi Uday, If I do c-h k and then drag a file into the vm-composition
buffer, I get this:

<ns-drag-file> runs the command ns-insert-file, which is an
interactive compiled Lisp function in `ns-win.el'.

It is bound to <ns-drag-file>.

(ns-insert-file)

Insert contents of file `ns-input-file' like insert-file but with less
prompting. If file is a directory perform a `find-file' on it.

so doesn't work on a Mac for me... let me know if there is anything I can do...

Do you have drag and drop working in Emacs at all? If it is not
implemented for Mac's, there is nothing I can do I am afraid.

Uday

This page has some ideas on how to get drag and drop working in Emacs
under Mac.

http://anxiousmofo.wordpress.com/2008/07/19/getting-gnu-emacs-to-play-nicely-on-mac-os-x/

drag and drop does work, as when I drag a file to the vm buffer its
contents are entered as text. also, when I drag a directory, emacs is
starting dired on that directory. I think the issue may be that under
ns (Mac), the implementation uses slightly different commands bound to
the drag and drop operation, as mentioned in my previous email. I'll
play with this a bit and let you know. you should be using a mac,
it's fun (and it's unix)... :)

Yeah, I know, one of these days I will probably buy a mac...

Can you do C-h v for dnd-protocol-alist in a mail composition buffer
and tell me what the value is? Emacs is supposed to pick up the
handler from there.

Cheers,
Uday

You should also check the value of dnd-protocol-alist in a dired
buffer. Then we can compare the two.

Cheers,
Uday

vm does appear in this, so the problem may be that the drag operation
under ns does not use dnd.el

Value: (("^file:///" . vm-mail-dnd-attach-file)
 ("^file://" . dnd-open-file)
 ("^file:" . vm-mail-dnd-attach-file)
 ("^file:///" . dnd-open-local-file)
 ("^file://" . dnd-open-file)
 ("^file:" . dnd-open-local-file)
 ("^\\(https?\\|ftp\\|file\\|nfs\\)://" . dnd-open-file))

Original value was
(("^file:///" . dnd-open-local-file)
 ("^file://" . dnd-open-file)
 ("^file:" . dnd-open-local-file)
 ("^\\(https?\\|ftp\\|file\\|nfs\\)://" . dnd-open-file))

Local in buffer mail to _ on ""; global value is
(("^file:///" . dnd-open-local-file)
 ("^file://" . dnd-open-file)
 ("^file:" . dnd-open-local-file)
 ("^\\(https?\\|ftp\\|file\\|nfs\\)://" . dnd-open-file))

here are the values for dired buffer. but note that these values may
not be used. please see ns-win.el for what I think is actually being
called. cheers, E

Value: (("^file:///" . dired-dnd-handle-local-file)
 ("^file://" . dired-dnd-handle-file)
 ("^file:" . dired-dnd-handle-local-file)
 ("^file:///" . dnd-open-local-file)
 ("^file://" . dnd-open-file)
 ("^file:" . dnd-open-local-file)
 ("^\\(https?\\|ftp\\|file\\|nfs\\)://" . dnd-open-file))

Original value was
(("^file:///" . dnd-open-local-file)
 ("^file://" . dnd-open-file)
 ("^file:" . dnd-open-local-file)
 ("^\\(https?\\|ftp\\|file\\|nfs\\)://" . dnd-open-file))

Local in buffer applicant-files-EPS; global value is
(("^file:///" . dnd-open-local-file)
 ("^file://" . dnd-open-file)
 ("^file:" . dnd-open-local-file)
 ("^\\(https?\\|ftp\\|file\\|nfs\\)://" . dnd-open-file))

Ok, the next thing to do is how the dired dnd is working. Can you test
it out by dnd'ing into dired buffers? Place a debug-on-entry on the
corresponding dired functions to see if they are getting called and how.

Cheers,
Uday

People here seem to think that the dnd library is getting used on Mac.

http://www.mackb.com/Uwe/Forum.aspx/mac-apps/17862/Download-files-from-within-emacs-on-Mac-OS-X

sorry, I wasn't clear. drag and drop does work for me in general: if
I drag a file, its contents are entered into the buffer as text, if I
drag a directory, it is opened in dired. however, I think this may be
done via different commands from those in dnd.el. I could be totally
wrong as always, though. see the c-hv output I sent you previously,
which to my understanding means that some ns-specific functions are
being called, and I think they are defined in ns-win.el rather than
dnd.el. does this make sense at all? cheers, E

Yes. What we are trying to do is to find out whether dnd.el is being
supported on Mac. If you do the experiment I mentioned about dragging
into dired buffers, we will know.

Cheers,
Uday

OK. I put debug on entry on all functions in dnd.el, none was
triggered when I drag a directory into an emacs/ dired buffer

then I did the same with ns-insert-file, and that was triggered immediately:

Debugger entered--entering a function:
* ns-insert-file()
  call-interactively(ns-insert-file nil nil)

did I finally get it?

Yeah, that was useful information. I have added a function for ns and
bound it to [ns-drag-text]. Revision 1062. Please give it a try.

Cheers,
Uday

Final fixes in revision 1065.
