Subject: 24.5; trash-directory uses FreeDesktop location on OSX
Date: Mon, 24 Aug 2015 12:55:19 -0400

I set "(setq delete-by-moving-to-trash t)", and emacs moved
deleted files to ~/.local/share/Trash, the FreeDesktop location.
The files should have been moved to ~/.Trash, the standard OSX
location. I was deleting files in my home directory using dired.

Work around: (setq trash-directory "~/.Trash")

I get emacs from http://emacsformacosx.com/

You need to customize that variable to point to the directory where
you want your trash.  The doc string says:

    Directory for `move-file-to-trash' to move files and directories to.
  This directory is only used when the function `system-move-file-to-trash'
  is not defined.
  Relative paths are interpreted relative to `default-directory'.
  If the value is nil, Emacs uses a freedesktop.org-style trashcan.
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The default is nil, so what you see is Emacs functioning as designed.

I guess I considered it a bug, because `system-move-file-to-trash` is
used by Emacs for Windows to put files in the correct location. If Emacs
can cater to Windows, surely it can cater to another very largely used
OS? Emacs putting files in ~/.local on OSX just makes it appear that it
doesn’t know what it is doing.

Thank you all the same.

It doesn't cater to Windows, it caters to any platform that has a
'system-move-file-to-trash' primitive (which is supposed to know the
location of trash internally), and Windows just happens to have it.
When such a primitive is not available, Emacs moves the file using the
"normal" file I/O, and then it has to know where to move it.

I don't use OS X, but it sounds to like it would be better to change the
default value of trash-directory to

(if (eq system-type 'darwin) "~/.Trash/")

Or to define a system-move-file-to-trash, which defers to the
(presumably existing) system function that does that for us.

Alan, do you know whether this would make sense on Macos?

If not, then I think Glenn's suggestion here makes sense, i.e., add:

(if (eq system-type 'darwin) "~/.Trash/")

It looks like there's a method available to trash items on macOS 10.8
and above, so I suppose that's the logical thing to use.

https://developer.apple.com/documentation/foundation/nsfilemanager/1414306-trashitematurl?language=objc

macOS < 10.8 uses some Carbon API, which I'd rather not bother with,
and GNUstep doesn't support it at all, so I imagine it's as well using
the XDG location or whatever the default is.

Well, I've written a patch but the function doesn't appear in lisp and
I don't know what I've done wrong.

Patch attached.

I think you're just missing the defsubr for the symbol:

  defsubr (&Ssystem_move_file_to_trash);

That was it, thank you!
