How to pass an object-path over d-bus from emacs?

How to pass an object-path over d-bus from emacs?

[Fran Burstall (Gmail)]

I am using the excellent dbus.el library.

Q: How do I feed a parameter of type o (object-path) over d-bus from
emacs-lisp?

My reading of the docs is that something of the form

    (list :variant (list :object-path "/some/path/here"))

should do the job.  But the receiving application complains:

   playerctl-WARNING **: 20:10:52.843: mpris:trackid is a string, not a
D-Bus object reference

Any idea what I am missing?

If you just need the object path, say ':object-path "/some/path/here"'
(w/o the surrounding apostrophes). See the examples in
.../test/lisp/net/dbus-tests.el

Using Tramp from Lisp

[Jean Louis]

Michael, let me know if I can use Tramp from Lisp as easy for purpose to transfer file to remote server?

I am using my own SCP and rsync based functions. Maybe it is not necessary if Tramp provides it.

And I like to specify username instead of using config files.

That is exactly the raison d'être of Tramp.

No. Copying a file is (copy-file "/path1/source" "/path2/target") Doing
the same for a remote host, it is (copy-file "/path1/source" "/scp:user@host:/path2/target")
That's all. In fact, for the mafority Lisp functions handling files, you
can use a file name in its remote syntax. copy-file is just an example.

Tramp supports many connection methods, besides "ssh" it also supports
"cp" and "rsync".

As shown in the example, it is possible. Perhaps you read the Tramp
manual, for example (info "(tramp)File name syntax")

I hope that copy file will be as fast as direct function using scp/rsync, I must test it today.
