Hi,
I got below error after I called (org-notify-start). It seems the
dbus-error happens very close to the task notification. I wonder if
org-notify uses dbus.
Error: (dbus-error "No connection to bus" :session)
Warning: notification for "Go to dental in 30 mins." behind schedule!
Error: (dbus-error "No connection to bus" :session) [2 times]
Warning: notification for "Go to dental in 30 mins." behind schedule!
Error: (dbus-error "No connection to bus" :session) [2 times]
I am using Emacs on Windows, and there's no dbus on Windows...
Thanks,
David

It seems so, yes: org-notify calls notifications-notify from the emacs
notifications.el library.
Clearly, notifications.el relies on dbus.
However, if you are using Mingw64, there is a dbus package which should
provide
what is needed. Unfortunately, I tried it and can't tell yet how to
configure it or if it
even works.

Yeah...getting dbus to work on Windows will be hard. Maybe we should
consider using some other ways to display a notification on Windows.
E.g. On Windows/Cygwin environment, org-notify should use a command line
tool to show a notification in the Windows notification area.
But I wonder how to deploy this command line tool with Emacs system...any
suggestions/ideas?
Thanks,
David

Actually, not so much. Dbus does work on windows. It doesn't work right now
on emacs. I'm looking into it.

Well~that's good news. But I think dbus requires X11 to work. But in Cygwin
environment, people usually do not configure a full X11 environment.
Besides, for org-notify, could dbus help it playing a notification sound on
Windows? Or popup a notification message?
So what I am thinking is to get some Windows native behavior for org-notify
on Windows/Cygwin environment.

I don't think that's true: dbus is "just" a message bus - an IPC
mechanism that different processes use to communicate. It has nothing to
do with X11 or any other windowing protocol.
The dbus-daemon manual page says:
The systemwide daemon is largely used for broadcasting system events, such as changes
to the printer queue, or adding/removing devices.
The per-session daemon is used for various interprocess communication among desktop
applications (however, it is not tied to X or the GUI in any way).
What makes you think that it requires X11?

Sure it could: you send a message on the dbus saying "play a sound" and some other
process listening on the dbus gets the message and plays a sound.

Bad idea imo.

No, dbus doesn't require X11 to work. Neither does emacs require Cygwin to
work.
Actually, Emacs compiles as a native Windows application (using MinGW32 or
MinGW64) and it is also the case of dbus.

I guess it will work the same way it does elsewhere.

I too think that a native, session only module that will provide the same
interface as dbus could be interesting
for Windows users. However, that shouldn't prevent those who want to use
dbus to use it.
AFAIU, using dbus, you could have a distant running emacs (ssh) session and
get notifications on your local desktop,
provided the right setup.
Well, browsing the source code, I see that Eli Zaretskii has already
implemented native win32 tray notifications.
They are a small subset of the dbus notifications.
However, he made them exclusive with dbus. I don't see the reason yet.

I also think it is a good idea to add some functions in Emacs for Win32
platform, and let other's used those functions from elisp. Thanks~
