Thanks,
that was the "print -s" I was looking for. I thought vared would insert
the line by itself in the history list. Here is what I have, it replaces
the terminal line editor (that only supports <Backspace>, <Ctrl-U>,
<Ctrl-W> with zsh line editor (which supports arrows, Ctrl-A, history...
no need for readline anymore):
#! /usr/bin/env zsh
trap 'printf "\03"; exit' INT
HISTSIZE=100
while a=; vared -p "$2" -eh a; do
{
s=$(stty -g)
stty -echo -iexten -isig lnext '' werase '' eof '' rprnt '' kill ''
printf "%s\r" "$a"
print -rs -- "$a"
stty "$s"
} < $1
done
printf "\04"
To be run as a :exec filter withing screen (with .!. as first argument
to exec and "$(tty)" as first argument to the script.
