Hello,
I saw codes on the internet that advise doing "zle && zle
reset-prompt" when wanting a Zle change from a sched call, e.g. here (on
the bottom, last 11 item):
http://chneukirchen.org/blog/archive/2013/03/10-fresh-zsh-tricks-you-may-not-know.html
I once too occurred sched calls that indeed were zle == false, and
added such "zle &&" guard too. Now when I test I always get zle
active. When to expect lack of zle, can this be predicted? Will
re-scheduling (with +1 second) help?
Best regards,
Sebastian Gniazdowski

It's not guaranteed that zle will be active during a sched call.
Sched is generally handled as part of the pre-prompt functions; there is
no intended linkage between this and zle. Any interaction is not
thought out (to my knowledge --- and sched is an old function that
hasn't been tinkered with for a long time, I think).

That for a moment sounded scary as if sched wouldn't be considered
important. I just finished initial version of a Zconvey plugin. It
integrates multiple Zsh sessions and will serve as a base for other
plugin that will make all this semi-graphical. I use sched to pull a
flock-guarded text file, to see if there are commands to run. You said
Zle isn't thought to be working with Sched but the miraculous ioctl(
0, TIOCSTI, c ); saved me totally, everything works, I can update
command line from Sched:

Maybe Sched could be revisited a little and pulled up to work with
Zle, .kill-buffer at least?
