FocusLost and FocusGained seem to have some problems when dealing with
system() calls.
Starting with gvim -N -u NONE -i NONE, the first script (at the end of
this message) echos:
system command
focus gained
I would expect it to also echo "focus lost".
The second script echos:
system command
focus gained
I would expect it to only echo "system command".
More succinctly, FocusLost is never called with a system command even
though FocusGained is, and FocusGained is always called even if its
event is supposedly being ignored.
Since FocusLost/FocusGained often come in pairs which assume the
presence of the other, this can cause some weird problems.
First script:
autocmd FocusLost * echomsg "focus lost"
autocmd FocusGained * echomsg "focus gained"
echomsg system("echo system command")
Second script:
autocmd FocusLost * echomsg "focus lost"
autocmd FocusGained * echomsg "focus gained"
set ei=all
echomsg system("echo system command")
set ei&
