Mouse interaction in -nw

Mouse interaction in -nw

[Ergus]

Hi:

I have been noticing some recent issue in xterm-mouse-mode not sure if
they are issues or features.

1) emacs -Q -nw
2) M-x xterm-mouse-mode
3) Select a region (like the word "buffer" in the scratch) with the mouse
4) M-w

5) Try to paste the word anywhere

In my system it seems that the mouse highlights the region properly,
but never moves the mark. So after M-w it copies the region between
point and original mark position not the selected word.

Is this intended? Because in gui this works "as expected"

Best,
Ergus

You mean like with `M-> C-y` ?
Works for me,

Hi Stefan:

Look at the attached gif. Where I select with the mouse several time,
and then M-w; but the region (mark) is not "properly updated" to the
selected region, just the point is updated, not the mark.

Actually the mouse selection does not act as the region at all. Maybe
this is intended... I just don't get why.

I can only set the mark with C-SPC?

The mouse selection seems to be done "by the terminal" rather than "by
Emacs".  IOW, it looks like the mouse clicks aren't passed to Emacs.
Time to check `C-h l`?
What text-terminal is that?

Hi Stefan:

I repeated the same with only xterm (to remove tmux and simplify)

And loosage shows:

  ESC x			 ;; execute-extended-command

Sorry but I don't know what's going on at this point :( I can't disable
more mouse events in xterm. 

This is my xterm config (just in case):

This looks right except for a missing

     ESC [ < 0 ; 4 5 ; 2 m   ;; anonymous-command
     <drag-mouse-1>          ;; mouse-set-region

just before the `ESC w`.  IOW it looks like you get the mouse-down and
mouse-motion events but for some reason Emacs didn't get the mouse-up
event (encoded as `ESC ... m`), which is the one that actually sets
the region.

I don't know why that would happen.  I'd assume it's something to do
with the `xterm` executable or its configuration, but as for
what... I recommend you try it with some other terminal emulator and
also that you try it with a different xterm config, just to try and
narrow down the scope of the problem.

Hi Stefan:

Thanks for your help. With your hint and checking my config Y found that
the problem was this line:

*omitTranslation: fullscreen,popup-menu,select,wheel-mouse

specifically omitTranslation for "select"

I am not totally sure yet if this is intended or an issue and I could
comment to xterm developer if this is fine.

Best,
Ergus

RE: Mouse interaction in -nw

[Drew Adams]

Is option `mouse-drag-copy-region' relevant for
emacs -nw?  If so, is your value of it non-nil?

(Just a thought - may not be relevant/helpful.)
