Subject: 29.3; Drag and drop in Emacs 29 on macOS
Date: Mon, 8 Jul 2024 18:32:02 -0400

* SUMMARY

Drag and drop does not work in Emacs version 29 on macOS.


* DESCRIPTION

- Drag and drop does NOT work on Emacs 29 on macOS. (Drag
  and drop DOES work in Emacs < 28. Upgrading to v29 makes
  drag and drop stop working.)

- If we do M-x describe-key then drag and drop a file on the
  text area of the window, we get
  - nothing -- in Emacs 29
  - a spurious message -- in Emacs 28
  - a normal message -- in Emacs 26


* USE CASE 1

- App: Emacs 29.x
  1. emacs -Q
  2. drag and drop a file from macOS Finder to Emacs

** EXPECTED BEHAVIOR

  3. file should open in Emacs

** ACTUAL BEHAVIOR

  3. NOTHING HAPPENS

  |-------+---------------------|
  | Emacs | Drag-n-Drop         |
  |-------+---------------------|
  |  29.3 | NOTHING HAPPENS     |
  |  28.2 | drag-and-drop works |
  |  26.3 | drag-and-drop works |
  |-------+---------------------|


* USE CASE 2

  1. M-x describe-key
  2. Drag and drop a file from Finder to Emacs

** EXPECTED BEHAVIOR

  3. should receive an informative message like
     “<drag-n-drop> ... runs ... ns-drag-n-drop ...”

** ACTUAL BEHAVIOR

  3. Results below. Regarding v28, even though drag-and-drop
     itself works fine in v28, we get this spurious
     “position not in text area” message. It is spurious
     because we indeed drag and drop the file into the text
     area.

  |  28.2 | “Position not in text area of window”       |

Since I cannot reproduce this in GNUstep on Emacs 30, this has either
been dealt with in the release branch, or is specific to Mac OS.

Who maintains the macOS-specific code?

Drag and drop works fine for me on macOS with Emacs 29.3 and
master. Is this one of those 'apps need permission to access folders'
security things that pops up every once in a while on macOS?

Thank you for that suggestion. However, there is no error message. It just silently does not work. Search for the string "NOTHING HAPPENS" in my bug report. Also note that rolling back to Emacs 28 or going to a more recent macOS makes drag and drop work.

What other reasons could we think of, to explain why Emacs 29 drag and drop does not work in macOS 12, an OS that is only three years old, still supported and updated, and still widely used?

macOS 12 | Emacs 28 | works
macOS 12 | Emacs 29 | does not work
macOS 14 | Emacs 28 | works
macOS 14 | Emacs 29 | works

The above recipe works for me too (the file opens) on macOS 14.5 in
emacs -Q, tested on master and Emacs 29.4.

Ah, so this is Appleʼs fault 😉

"Why does Apple change APIs so that they break drag and drop" is
another way of asking that question.

I donʼt have a macOS 12 machine, so I canʼt test. Alan, would you have
any ideas?

My Mac is still running 10.14 or something equally ancient, so I doubt
I'll be much help in diagnosing this, but it smells a little to me of
an incorrect #if statement somewhere.

You mean the MAC_OS_X_VERSION_MIN_REQUIRED? It looks like that
influences how Emacs interacts with the PasteBoard.

Giah, did you build your emacsen yourself? Or are these from homebrew
or similar?

Thanks

Yes, these are from homebrew. Thanks.

Sorry, I spoke too soon. These are all from emacsformacosx.com.

I'm not quite up to date on the status of the various macOS builds,
but it might be worth trying Jim's build:

    https://github.com/jimeh/emacs-builds

or try building it yourself.

In Jim’s build, yes, drag and drop works, but it still does this:

1. C-h k (describe-key)

2. Drag and drop something into the text
   area of the window.

3. Emacs incorrectly complains:
   "Position not in text area of window"

And PDF viewing is broken on Jim’s build (DocView complains “the pdf process exited abnormally”).

Hmm, that makes me think that the issue is something to do with
David's build scripts for emacsformacosx.com. You could try reporting
it to him if you want. I think the bug reporting info is on the
website.

I'm not sure but you may have to drop into the minibuffer while using
describe-key.

I'm not sure what's needed there. You could again try reporting it to
Jim directly.

The alternative is trying to build it yourself, which is actually
relatively easy if you're already using homebrew or macports.

Sorry for the long delay in replying.
