[vim/vim] Mouse selection not visible with ttymouse=xterm2, mouse=a and channel-based plugin (#4524)
Paul Jolly
Describe the bug
Apologies in advance for likely using the wrong language below when it comes to precisely referring to terminal-based mouse selection vs visual selection in Vim
I have the following in my .Xresources:
XTerm*VT100.Translations: #override \
Mod1 <KeyPress> V : insert-selection(CLIPBOARD,PRIMARY,CUT_BUFFER1) \n\
Shift ~Ctrl<Btn2Up> : insert-selection(CLIPBOARD,PRIMARY,CUT_BUFFER1) \n\
<BtnUp> : select-end(CLIPBOARD,PRIMARY,CUT_BUFFER1) \n\
!Ctrl <Btn1Down> : ignore() \n\
!Ctrl <Btn2Down> : ignore() \n\
!Ctrl <Btn3Down> : ignore() \n\
Shift <BtnUp> : select-end(CLIPBOARD,PRIMARY,CUT_BUFFER1) \n\
!Lock Ctrl <Btn3Down> : ignore() \n\
!Lock Ctrl @Num_Lock <Btn3Down> : ignore() \n\
! @Num_Lock Ctrl <Btn3Down> : ignore() \n\
Ctrl <KeyPress> F9 : print() \n
This means that I hold down Shift in Vim, then click with the left mouse button in order to make a terminal-based (correct terminology?) selection that is copied to the clipboard. Not holding down Shift and clicking leads to Vim creating a visual selection.
In my .vimrc I have:
set mouse=a
set ttymouse=xterm2
However, when I have govim loaded, then something strange happens with the terminal-based selection: the white background that indicates what is selected does not appear until I release the mouse button. Once the mouse button is released, the correct text is selected, the white background shows the selected text, and the text is copied to the clipboard. But it's just that as I am dragging (whilst holding down Shift, as explained) with the mouse button down, there is no white background, so I can't see what I have/haven't selected.
I haven't been able to reproduce this with a channel-based plugin other than govim. But it reproduces even it govim itself does nothing, i.e. main function simply returns.
From what I can tell, this has always been the case as far back as v8.1.1158.
If I set ttymouse=xterm the problem goes away, i.e. the white background shows as the selection grows.
Similarly, if I don't load govim, the problem goes away.
Any suggestions on how to further bisect this would be appreciated.
