Very nice, thank you!  And congratulations.

I can't find anything about this in NEWS, though.

Thanks, one thing less to try to not forget :-). Or two actually, with
the not pausing for input, even better.

I'll add one real soon now (tm). Need to synchronize with GNU first.

Now done, but it would be nice if someone could check if that's
sufficient and so on.

Thanks!

Can't answer your question, but I just stumbled over the last paragraph
above. Changing a root to a child frame or vice versa is also not
supported on ttys.

Hi Michael,

The new code now _requires_ a tty frame to be used (decode_tty_frame,
check_tty), which I think the tests can't provide, running in batch. And
I'd rather not be less picky for the sake of these tests.

Kind of a predicament. Any idea what could be done?

Why is that a problem?  A batch session does have a frame, you just
need to account for that.  I think the test that emits the error is
too strict, and should be relaxed when noninteractive is non-zero.  Or
maybe invert the test and check for !FRAME_WINDOW_P (which would then
allow the frame that exists in the batch session).

You mean why removing the checks (decode_tty_frame, check_tty) is a
problem?. My question is more what these tests bring tot he table that
outweighs removing checks.

I know it has an initial frame, which is neither a tty nor a window
system frame. The idea of testing xt-mouse with that is, let's say,
interesting. And then that comment

;; FIXME: this doesn't work when called inside a non-batch mode Emacs

I could maybe make check_tty not signal if noninteractive == true. I
guess that could make things work, one has to try, but it surely doesn't
win a beauty price :-(.

That frame is very much like a tty frame, AFAIR.  I suggest to try
relaxing the test and seeing if the xt-mouse tests then pass.

If it makes a test work, why not?  We can even document this in a
comment.
