You can't do this in the obvious way. The prompts (both left and right)
are computed just after the `precmd' function runs, and then subsequent
ZLE refreshes only repaint them; so changes to PROMPT, RPROMPT, et al.,
during widget execution have no effect.
Here are some possible alternatives; the first one both changes and
covers up the RPROMPT, the second one merely moves the command onto a
line by itself and leaves the prompts alone.
switch-rprompt() {
if [[ -z "$RPROMPT" ]]; then
setopt localoptions extendedglob
export RPROMPT="$MYRPROMPT"
RBUFFER="${RBUFFER%% #}"
else
export RPROMPT=""
RBUFFER="$RBUFFER${(l:COLUMNS:: :):-}"
fi
}
switch-rprompt() {
setopt localoptions noksharrays
if [[ "$BUFFER" == $'\\\n'* ]]; then
((CURSOR -= 2))
BUFFER="$BUFFER[3,-1]"
else
LBUFFER=$'\\\n'"$LBUFFER"
fi
}
