} There seems to be a bug in the prompt update. The change of psvar[1]
} in TRAPCHLD is not taken into account for the next prompt display,
} but for the following one.
That's because the prompt is being redrawn before TRAPCHILD executes.
If you change it to:
TRAPCHLD() { psvar[1]=$RANDOM; print "set $psvar[1]" }
You can see where the print output appears relative to the prompt:
18:50:09-% sleep 7 & sleep 5 & sleep 9 &
[1] 18276
[2] 18277
[3] 18278
18:50:11-%
[2] - done sleep 5
18:50:16-% set 23539
[1] - done sleep 7
18:50:18-23539% set 5119
[3] + done sleep 9
18:50:20-5119% set 17622
The right thing is to explicitly tell ZLE to update the prompt:
TRAPCHLD() {
psvar[1]=$RANDOM
[[ -o zle ]] && zle reset-prompt
}
Or perhaps your complaint is that the TRAP* function should run sooner?
