Description Wouter Van Hemel 2020-01-21 13:28:49 UTC
Recent versions of Vim have text balloons that can show information on mouse-over. These balloons should work in non-graphical terminals, too, using the following settings:

set mouse=a
set ttymouse=sgr

set updatetime=1500
set balloondelay=300
set ballooneval
set balloonevalterm

However, this functionality doesn't seem to be working in Konsolepart-based terminal emulators like Konsole and Yakuake.

STEPS TO REPRODUCE
1. Enable govim or any other vim extension that uses balloon pop-ups;
2. Open some source code;
3. Hover a keyword.

OBSERVED RESULT
On mouse-over, nothing happens in konsole or yakuake; no balloon appears. Keyboard shortcuts do show the text balloon with information, so the problem is with vim not noticing the mouse pointer is located over a keyword. Mouse movements do not seem to be detected; basic mouse functionality such as clicks and selection work fine, though.

EXPECTED RESULT
I expect that when moving the mouse pointer over a keyword, vim triggers a text balloon to be shown. This functionality works by default in other terminals, e.g. Alacritty.

My guess is that the terminal emulation code doesn't report mouse movements to vim, either because it's not supported or because the terminfo entry isn't complete. Alternatively, I could have somehow managed to mess up the settings so Konsole would have disabled some terminal functionality.

ADDITIONAL INFORMATION

In short: no vim text balloons on mouse-over in Konsole while they show up in other terminal applications.
